En este sentido, la detecci\u00f3n simult\u00e1nea de dos o m\u00e1s fotones permite explotar las caracter\u00edsticas no cl\u00e1sicas de la luz, las cuales se manifiestan mediante correlaciones que no son posibles en una descripci\u00f3n cl\u00e1sica. Presentamos aqu\u00ed el desarrollo de m\u00f3dulos programables, basados en tecnolog\u00eda FPGA, que componen el sistema de detecci\u00f3n y conteo de pulsos en coincidencias. La arquitectura implementada en una placa de desarrollo de la firma Xilinx, permite determinar cu\u00e1ndo dos o m\u00e1s pulsos coinciden dentro de una ventana temporal, cuyo ancho puede configurarse entre 1 y 255 ns para compensar posibles diferencias de camino.\r\nComo producto de las medidas de pulsos individuales y en coincidencias, se obtuvieron y compararon las estad\u00edsticas de detecci\u00f3n con las predichas te\u00f3ricamente. Adicionalmente, se emularon las se\u00f1ales correspondientes a diferentes fuentes de fotones a trav\u00e9s de un divisor de haz, y se obtuvieron las estad\u00edsticas de fotodetecci\u00f3n a partir de las cuales se determin\u00f3, para cada caso, la funci\u00f3n de correlaci\u00f3n de segundo orden g(\u00b2)(\u03c4).\n\nThe detection of temporally coincident signals plays an important role in different technological applications for metrology and communication, and particularlly, in the area of quantum optics. In this sense, the simultaneous detection of two or more photons allows one to take advantage of the non-classical features of light that manifest themselves in certain types of correlations that cannot be described classically. We present here the development of programmable modules, by using FPGA technology, which are part of the coincident pulse detection and counting system. Our implementation, in a development board from Xilinx, allows to determine when two or more pulses overlap within a temporal window, with a configurable width in the range of 1 and 255 ns to compensate for possible path differences.\r\nWe obtained the photodetection statistics result of the single and coincident pulse measurements, and compared them with that predicted by a theoretical analysis. In addition, we have emulated the signals corresponding to different photon sources through a beam splitter, and obtained the photodetection statistics from which we determine, for each case, the second order correlation function g(\u00b2)(\u03c4).<\/span><\/div><\/summary><div class=\"a_unline\">Compartir: <a href=\"https:\/\/www.facebook.com\/sharer\/sharer.php?p[title]=Desarrollo de un sistema para el conteo de m\u00faltiples se\u00f1ales en coincidencia basado en tecnolog\u00eda FPGA&p[url]=http:\/\/sedici.unlp.edu.ar\/handle\/10915\/153411\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-facebook.png\" alt=\"Facebook logo\" title=\"Compartir en Facebook\">\n             <\/a>\n             <a href=\"https:\/\/twitter.com\/?status=Desarrollo de un sistema para el conteo de m\u00faltiples se\u00f1ales en coincidencia basado en tecnolog\u00eda FPGA http:\/\/sedici.unlp.edu.ar\/handle\/10915\/153411 via @sedici_unlp\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-twitter.png\" alt=\"Twitter logo\" title=\"Compartir en Twitter\"><\/a>\n             <a href=\"https:\/\/plus.google.com\/share?url=http:\/\/sedici.unlp.edu.ar\/handle\/10915\/153411\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-plus.png\" alt=\"Google+ logo\" title=\"Compartir en Google+\">\n             <\/a>\n             <a href=\"http:\/\/www.linkedin.com\/shareArticle?url=http:\/\/sedici.unlp.edu.ar\/handle\/10915\/153411\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-linkedin.png\" alt=\"Linkedin logo\" title=\"Compartir en Linkedin\">\n             <\/a>\n        <\/div><\/article><\/li><li><article>\n\t\t\t<title>Descarga de un sif\u00f3n que contiene un fluido viscoso<\/title>\n                        <div id=\"sedici-title\">\n                            <a href=\"http:\/\/sedici.unlp.edu.ar\/handle\/10915\/156477\" target=\"_blank\">Descarga de un sif\u00f3n que contiene un fluido viscoso<\/a>\n                        <\/div><div id=\"sedici-title\">Autores: <author><name><a href=http:\/\/sedici.unlp.edu.ar\/discover?filtertype=author&filter_relational_operator=equals&filter=Devece%2C%20Eugenio target=\"_blank\">Devece, Eugenio<\/a><\/name><\/author>-<author><name><a href=http:\/\/sedici.unlp.edu.ar\/discover?filtertype=author&filter_relational_operator=equals&filter=Videla%2C%20Fabi\u00e1n%20Alfredo target=\"_blank\">Videla, Fabi\u00e1n Alfredo<\/a><\/name><\/author>-<author><name><a href=http:\/\/sedici.unlp.edu.ar\/discover?filtertype=author&filter_relational_operator=equals&filter=Costa%2C%20Viviana%20Ang\u00e9lica target=\"_blank\">Costa, Viviana Ang\u00e9lica<\/a><\/name><\/author>-<author><name><a href=http:\/\/sedici.unlp.edu.ar\/discover?filtertype=author&filter_relational_operator=equals&filter=Fern\u00e1ndez%20Lobo%2C%20Gonzalo%20Miguel%20Joaqu\u00edn target=\"_blank\">Fern\u00e1ndez Lobo, Gonzalo Miguel Joaqu\u00edn<\/a><\/name><\/author><\/div><published>\n                                        <div id=\"sedici-title\">Fecha: <span class=\"sedici-content\">2023-01-01<\/span><\/div>\n                                    <\/published><dc:type>\n                                        <div id=\"sedici-title\">Tipo de documento: <span class=\"sedici-content\">Objeto de conferencia<\/span><\/div>\n                                    <\/dc:type><summary> <div id=\"sedici-title\">Resumen:<span class=\"sedici-content\">En el contexto de una clase correspondiente al tema Hidrost\u00e1tica del segundo m\u00f3dulo de la asignatura F\u00edsica I, se propone realizar un experimento cuya implementaci\u00f3n consiste en un dispositivo empleado para trasvasar l\u00edquidos de un recipiente a otro. Para ensayar esta implementaci\u00f3n se midi\u00f3 el caudal de descarga de una cubeta de vidrio conteniendo agua descargada a trav\u00e9s de una manguera dispuesta en forma de \u201cU\u201d con un extremo sumergido en el l\u00edquido y otro libre a la atm\u00f3sfera. Planteando un modelo simplificado basado en la ecuaci\u00f3n de Bernouilli, se obtuvo una predicci\u00f3n de la velocidad de descarga. A partir de esa expresi\u00f3n se obtuvo una ecuaci\u00f3n diferencial para la velocidad y en consecuencia para el caudal en funci\u00f3n del tiempo.\r\nLa funci\u00f3n obtenida luego se compara con los registros experimentales observ\u00e1ndose un apartamiento entre el modelo y el experimento. Para remediar esta situaci\u00f3n se actu\u00f3 modificando el perfil de velocidad considerando en forma fenomenol\u00f3gica la distribuci\u00f3n transversal de velocidades en un tubo cil\u00edndrico.\r\nPor otra parte se elabor\u00f3 una simulaci\u00f3n del experimento empleando el software GeoGebra esperando mejorar la comprensi\u00f3n de los fen\u00f3menos involucrados en la descarga y tambi\u00e9n asistir en las posibilidades de ajuste al momento de realizar comprobaciones experimentales comparando los resultados de medidas con los valores calculados con modelos menos simplificados. Adem\u00e1s el software posee controles deslizables que permiten obtener mejores ajustes en forma \u00e1gil y as\u00ed analizar las limitaciones de los modelos.\r\nFinalmente se presenta una encuesta destinada a los estudiantes que completa la evaluaci\u00f3n del software como herramienta de aprendizaje.

La aplicaci\u00f3n de las leyes de Newton al sistema modelado a\u00fan como part\u00edcula,conduce a una ecuaci\u00f3n diferencial de segundo orden cuyas soluciones permiten obtener la posici\u00f3n velocidad y aceleraci\u00f3n. Las soluciones son combinaciones lineales de funciones arm\u00f3nicas. En el contexto de la Materia F\u00edsica I de la Facultad de Ingenier\u00eda UNLP esta es la primera oportunidad en que se exploran aspectos cinem\u00e1ticos y energ\u00e9ticos cuando act\u00faan fuerzas variables en el tiempo. Para este cometido, se han representado por medio de simulaciones desarrolladas en Mathematica la evoluci\u00f3n de las variables cinem\u00e1ticas y energ\u00e9ticas y se las ha sincronizado con el movimiento tambi\u00e9n simulado de una masa conectada a un resorte. De esta forma, es posible conectar las gr\u00e1ficas con posiciones clave de la masa con la esperanza de mejorar la comprensi\u00f3n del movimiento y el balance entre energ\u00eda cin\u00e9tica , potencial y mec\u00e1nica. Una encuesta, constituye el corolario de este trabajo, y est\u00e1 dirigida a poner en juego la comprensi\u00f3n de conceptos tales como el \u00e1ngulo de desfasaje, los valores de velocidad y aceleraci\u00f3n en puntos clave etc. . Adem\u00e1s la simulaci\u00f3n es de por s\u00ed una herramienta de estudio, donde los alumnos pueden poner a prueba sus predicciones y afianzar sus conocimientos a trav\u00e9s de la repetici\u00f3n y observaci\u00f3n detallada ejecutada con la velocidad que necesitan para tal fin. En este sentido, la actividad suplementa la adquisici\u00f3n de conocimientos que permite la observaci\u00f3n directa de experimentos reales. La encuesta permitir\u00e1 tambi\u00e9n evaluar la efectividad de las simulaciones comprando respuestas contra aquellos que no realizaron simulaciones.<\/span><\/div><\/summary><div class=\"a_unline\">Compartir: <a href=\"https:\/\/www.facebook.com\/sharer\/sharer.php?p[title]=Aspectos cinem\u00e1ticos y energ\u00e9ticos: oscilador arm\u00f3nico horizontal&p[url]=http:\/\/sedici.unlp.edu.ar\/handle\/10915\/156480\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-facebook.png\" alt=\"Facebook logo\" title=\"Compartir en Facebook\">\n             <\/a>\n             <a href=\"https:\/\/twitter.com\/?status=Aspectos cinem\u00e1ticos y energ\u00e9ticos: oscilador arm\u00f3nico horizontal http:\/\/sedici.unlp.edu.ar\/handle\/10915\/156480 via @sedici_unlp\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-twitter.png\" alt=\"Twitter logo\" title=\"Compartir en Twitter\"><\/a>\n             <a href=\"https:\/\/plus.google.com\/share?url=http:\/\/sedici.unlp.edu.ar\/handle\/10915\/156480\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-plus.png\" alt=\"Google+ logo\" title=\"Compartir en Google+\">\n             <\/a>\n             <a href=\"http:\/\/www.linkedin.com\/shareArticle?url=http:\/\/sedici.unlp.edu.ar\/handle\/10915\/156480\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-linkedin.png\" alt=\"Linkedin logo\" title=\"Compartir en Linkedin\">\n             <\/a>\n        <\/div><\/article><\/li><li><article>\n\t\t\t<title>Effective super-bandwidth in laser pulses<\/title>\n                        <div id=\"sedici-title\">\n                            <a href=\"http:\/\/sedici.unlp.edu.ar\/handle\/10915\/144139\" target=\"_blank\">Effective super-bandwidth in laser pulses<\/a>\n                        <\/div><div id=\"sedici-title\">Autores: <author><name><a href=http:\/\/sedici.unlp.edu.ar\/discover?filtertype=author&filter_relational_operator=equals&filter=Neyra%2C%20Enrique%20Gustavo target=\"_blank\">Neyra, Enrique Gustavo<\/a><\/name><\/author>-<author><name><a href=http:\/\/sedici.unlp.edu.ar\/discover?filtertype=author&filter_relational_operator=equals&filter=Biasetti%2C%20Demian%20Ar\u00edstide target=\"_blank\">Biasetti, Demian Ar\u00edstide<\/a><\/name><\/author>-<author><name><a href=http:\/\/sedici.unlp.edu.ar\/discover?filtertype=author&filter_relational_operator=equals&filter=Vaveliuk%2C%20Pablo target=\"_blank\">Vaveliuk, Pablo<\/a><\/name><\/author>-<author><name><a href=http:\/\/sedici.unlp.edu.ar\/discover?filtertype=author&filter_relational_operator=equals&filter=Torchia%2C%20Gustavo%20Adri\u00e1n target=\"_blank\">Torchia, Gustavo Adri\u00e1n<\/a><\/name><\/author>-<author><name><a href=http:\/\/sedici.unlp.edu.ar\/discover?filtertype=author&filter_relational_operator=equals&filter=Ciappina%2C%20Marcelo%20F target=\"_blank\">Ciappina, Marcelo F<\/a><\/name><\/author>-<author><name><a href=http:\/\/sedici.unlp.edu.ar\/discover?filtertype=author&filter_relational_operator=equals&filter=Videla%2C%20Fabi\u00e1n%20Alfredo target=\"_blank\">Videla, Fabi\u00e1n Alfredo<\/a><\/name><\/author>-<author><name><a href=http:\/\/sedici.unlp.edu.ar\/discover?filtertype=author&filter_relational_operator=equals&filter=Reb\u00f3n%2C%20Lorena target=\"_blank\">Reb\u00f3n, Lorena<\/a><\/name><\/author><\/div><published>\n                                        <div id=\"sedici-title\">Fecha: <span class=\"sedici-content\">2021-01-01<\/span><\/div>\n                                    <\/published><dc:type>\n                                        <div id=\"sedici-title\">Tipo de documento: <span class=\"sedici-content\">Preprint<\/span><\/div>\n                                    <\/dc:type><summary> <div id=\"sedici-title\">Resumen:<span class=\"sedici-content\">We present here a theoretical analysis of the interaction between an ideal two-level quantum system and a super-oscillatory pulse, like the one proposed and successfully synthesized in J. Opt. 23, 075604 (2021). As a prominent feature, these pulses present a high efficiency of the central super-oscillatory region in relation to unavoidable sidelobes. Our study shows an increase in the effective bandwidth of the pulse in the super-oscillatory region, and not only the appearance of a local frequency higher than its highest Fourier-frequency component, as in the usual description of the phenomenon of super-oscillations. Beyond introducing the concept of effective super-bandwidth, the presented results could be relevant for experimental applications and opening new perspectives for laser\u2013matter interaction.<\/span><\/div><\/summary><div class=\"a_unline\">Compartir: <a href=\"https:\/\/www.facebook.com\/sharer\/sharer.php?p[title]=Effective super-bandwidth in laser pulses&p[url]=http:\/\/sedici.unlp.edu.ar\/handle\/10915\/144139\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-facebook.png\" alt=\"Facebook logo\" title=\"Compartir en Facebook\">\n             <\/a>\n             <a href=\"https:\/\/twitter.com\/?status=Effective super-bandwidth in laser pulses http:\/\/sedici.unlp.edu.ar\/handle\/10915\/144139 via @sedici_unlp\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-twitter.png\" alt=\"Twitter logo\" title=\"Compartir en Twitter\"><\/a>\n             <a href=\"https:\/\/plus.google.com\/share?url=http:\/\/sedici.unlp.edu.ar\/handle\/10915\/144139\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-plus.png\" alt=\"Google+ logo\" title=\"Compartir en Google+\">\n             <\/a>\n             <a href=\"http:\/\/www.linkedin.com\/shareArticle?url=http:\/\/sedici.unlp.edu.ar\/handle\/10915\/144139\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-linkedin.png\" alt=\"Linkedin logo\" title=\"Compartir en Linkedin\">\n             <\/a>\n        <\/div><\/article><\/li><li><article>\n\t\t\t<title>Evaluaci\u00f3n de la performance de filtros \u00f3pticos de uso oft\u00e1lmico utilizando distancias Eucl\u00eddeas<\/title>\n                        <div id=\"sedici-title\">\n                            <a href=\"http:\/\/sedici.unlp.edu.ar\/handle\/10915\/153685\" target=\"_blank\">Evaluaci\u00f3n de la performance de filtros \u00f3pticos de uso oft\u00e1lmico utilizando distancias Eucl\u00eddeas<\/a>\n                        <\/div><div id=\"sedici-title\">Autores: <author><name><a href=http:\/\/sedici.unlp.edu.ar\/discover?filtertype=author&filter_relational_operator=equals&filter=Ratto%2C%20Gustavo target=\"_blank\">Ratto, Gustavo<\/a><\/name><\/author>-<author><name><a href=http:\/\/sedici.unlp.edu.ar\/discover?filtertype=author&filter_relational_operator=equals&filter=Videla%2C%20Fabi\u00e1n%20Alfredo target=\"_blank\">Videla, Fabi\u00e1n Alfredo<\/a><\/name><\/author><\/div><published>\n                                        <div id=\"sedici-title\">Fecha: <span class=\"sedici-content\">2021-01-01<\/span><\/div>\n                                    <\/published><dc:type>\n                                        <div id=\"sedici-title\">Tipo de documento: <span class=\"sedici-content\">Articulo<\/span><\/div>\n                                    <\/dc:type><summary> <div id=\"sedici-title\">Resumen:<span class=\"sedici-content\">El estilo de vida de las sociedades actuales involucra el empleo intenso de pantallas a LED. La radiaci\u00f3n luminosa que emana de estos dispositivos posee alto contenido espectral en una regi\u00f3n identificada como fotot\u00f3xica (aproximadamente 380- 500 nm). La exposici\u00f3n a este tipo de radiaci\u00f3n es en parte responsable del \u201cestr\u00e9s ocular digital\u201d y de la alteraci\u00f3n de los ritmos circadianos. Frente a esta situaci\u00f3n se han sugerido un conjunto de medidas preventivas y paliativas, entre ellas el empleo de anteojos con capacidad para filtrar luz fotot\u00f3xica.\r\nEl presente trabajo compila, en lengua espa\u00f1ola, informaci\u00f3n relevante sobre la problem\u00e1tica y, mediante el uso de distancias Eucl\u00eddeas, como criterio para diferenciar espectros, presenta y discute la performance de distintas lentes disponibles en el mercado con el objetivo de brindar informaci\u00f3n orientativa sobre su potencial efectividad. Se analizaron lentes transparentes y pigmentadas espec\u00edficas (publicitadas como protectoras de exceso de luz azul) y pigmentadas no espec\u00edficas (bajo costo).\r\nNuestros resultados muestran que las lentes transparentes espec\u00edficas ensayadas no presentan un grado de atenuaci\u00f3n significativo en la regi\u00f3n fotot\u00f3xica. Por su parte, las lentes pigmentadas espec\u00edficas poseen, en general, una muy buena atenuaci\u00f3n mientras que las no espec\u00edficas poseen una moderada capacidad de atenuaci\u00f3n.\n\nThe lifestyle of today's societies involves the intensive use of LED screens. The light radiation emanating from these devices has a high spectral content in a region identified as phototoxic (approximately 380- 500 nm). Exposure to this type of radiation is in part responsible for \u201cdigital eye strain\u201d and the alteration of circadian rhythms. Faced with this situation, a set of preventive and palliative measures have been suggested, among them, the use of glasses with the ability to filter phototoxic light.\r\nThe present work compiles, in Spanish language, relevant information on the problematic involved and, by employing Euclidean distances as criterion to differentiate spectra, presents and discusses the performance of different lenses available in the market in order to provide information as guidance on their potential effectiveness. Specific pigmented and transparent lenses (advertised as protective against excess of blue light) and non-specific pigmented (low cost) lenses were analyzed. Our results show that the specific transparent lenses tested do not present a significant degree of attenuation in the phototoxic region. On the other hand, the specific pigmented lenses generally have a very good attenuation while the non-specific ones have a moderate attenuation capacity.<\/span><\/div><\/summary><div class=\"a_unline\">Compartir: <a href=\"https:\/\/www.facebook.com\/sharer\/sharer.php?p[title]=Evaluaci\u00f3n de la performance de filtros \u00f3pticos de uso oft\u00e1lmico utilizando distancias Eucl\u00eddeas&p[url]=http:\/\/sedici.unlp.edu.ar\/handle\/10915\/153685\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-facebook.png\" alt=\"Facebook logo\" title=\"Compartir en Facebook\">\n             <\/a>\n             <a href=\"https:\/\/twitter.com\/?status=Evaluaci\u00f3n de la performance de filtros \u00f3pticos de uso oft\u00e1lmico utilizando distancias Eucl\u00eddeas http:\/\/sedici.unlp.edu.ar\/handle\/10915\/153685 via @sedici_unlp\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-twitter.png\" alt=\"Twitter logo\" title=\"Compartir en Twitter\"><\/a>\n             <a href=\"https:\/\/plus.google.com\/share?url=http:\/\/sedici.unlp.edu.ar\/handle\/10915\/153685\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-plus.png\" alt=\"Google+ logo\" title=\"Compartir en Google+\">\n             <\/a>\n             <a href=\"http:\/\/www.linkedin.com\/shareArticle?url=http:\/\/sedici.unlp.edu.ar\/handle\/10915\/153685\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-linkedin.png\" alt=\"Linkedin logo\" title=\"Compartir en Linkedin\">\n             <\/a>\n        <\/div><\/article><\/li><li><article>\n\t\t\t<title>Design conditions in the middle range for implementation of integrated ring resonators in LiNbO\u2083 by direct laser writing<\/title>\n                        <div id=\"sedici-title\">\n                            <a href=\"http:\/\/sedici.unlp.edu.ar\/handle\/10915\/124345\" target=\"_blank\">Design conditions in the middle range for implementation of integrated ring resonators in LiNbO\u2083 by direct laser writing<\/a>\n                        <\/div><div id=\"sedici-title\">Autores: <author><name><a href=http:\/\/sedici.unlp.edu.ar\/discover?filtertype=author&filter_relational_operator=equals&filter=Pagano%2C%20Paula%20Luj\u00e1n target=\"_blank\">Pagano, Paula Luj\u00e1n<\/a><\/name><\/author>-<author><name><a href=http:\/\/sedici.unlp.edu.ar\/discover?filtertype=author&filter_relational_operator=equals&filter=Presti%2C%20Dami\u00e1n target=\"_blank\">Presti, Dami\u00e1n<\/a><\/name><\/author>-<author><name><a href=http:\/\/sedici.unlp.edu.ar\/discover?filtertype=author&filter_relational_operator=equals&filter=Peyton%2C%20Roberto%20Ram\u00f3n target=\"_blank\">Peyton, Roberto Ram\u00f3n<\/a><\/name><\/author>-<author><name><a href=http:\/\/sedici.unlp.edu.ar\/discover?filtertype=author&filter_relational_operator=equals&filter=Videla%2C%20Fabi\u00e1n%20Alfredo target=\"_blank\">Videla, Fabi\u00e1n Alfredo<\/a><\/name><\/author>-<author><name><a href=http:\/\/sedici.unlp.edu.ar\/discover?filtertype=author&filter_relational_operator=equals&filter=Torchia%2C%20Gustavo%20Adri\u00e1n target=\"_blank\">Torchia, Gustavo Adri\u00e1n<\/a><\/name><\/author><\/div><published>\n                                        <div id=\"sedici-title\">Fecha: <span class=\"sedici-content\">2020-06-01<\/span><\/div>\n                                    <\/published><dc:type>\n                                        <div id=\"sedici-title\">Tipo de documento: <span class=\"sedici-content\">Articulo<\/span><\/div>\n                                    <\/dc:type><summary> <div id=\"sedici-title\">Resumen:<span class=\"sedici-content\">The aim of this work is to design an integrated optical ring resonator to be implemented in LiNbO\u2083 with a 2.5\u2005mm radius and an operating wavelength of 1550\u2005nm. Considering these ring parameters, a free spectral range of 71.54\u2005pm and a quality factor of \u223c 5 \u00d7 10\u2075 were calculated. The authors apply results to improve the implementation of femtosecond laser writing in lithium niobate crystals. As it is well-known finite difference time domain method requires large memory and time for processing circuits with large footprint (few square mm), in contrast, the beam propagation method allows to simulate large bends in a simple way. RSoft suite design tools commonly represent circles by closed polygons whose geometrical parameters are not optimised to obtain bending losses as least as possible, as suggested by coherent coupling theory. In this sense, the suitable determination of a splice angle (in this case 1.44\u00b0), shape and length for segments are key parameters in the ring design. For this purpose, an <i>ad hoc<\/i> software was implemented to overcome this drawback. In summary, a 250 sided polygon side showed a suitable coupling performance and established a new layout approach for middle range rings.<\/span><\/div><\/summary><div class=\"a_unline\">Compartir: <a href=\"https:\/\/www.facebook.com\/sharer\/sharer.php?p[title]=Design conditions in the middle range for implementation of integrated ring resonators in LiNbO\u2083 by direct laser writing&p[url]=http:\/\/sedici.unlp.edu.ar\/handle\/10915\/124345\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-facebook.png\" alt=\"Facebook logo\" title=\"Compartir en Facebook\">\n             <\/a>\n             <a href=\"https:\/\/twitter.com\/?status=Design conditions in the middle range for implementation of integrated ring resonators in LiNbO\u2083 by direct laser writing http:\/\/sedici.unlp.edu.ar\/handle\/10915\/124345 via @sedici_unlp\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-twitter.png\" alt=\"Twitter logo\" title=\"Compartir en Twitter\"><\/a>\n             <a href=\"https:\/\/plus.google.com\/share?url=http:\/\/sedici.unlp.edu.ar\/handle\/10915\/124345\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-plus.png\" alt=\"Google+ logo\" title=\"Compartir en Google+\">\n             <\/a>\n             <a href=\"http:\/\/www.linkedin.com\/shareArticle?url=http:\/\/sedici.unlp.edu.ar\/handle\/10915\/124345\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-linkedin.png\" alt=\"Linkedin logo\" title=\"Compartir en Linkedin\">\n             <\/a>\n        <\/div><\/article><\/li><li><article>\n\t\t\t<title>Experiencia did\u00e1ctica mediada por TIC y elementos tradicionales para el estudio del movimiento circular<\/title>\n                        <div id=\"sedici-title\">\n                            <a href=\"http:\/\/sedici.unlp.edu.ar\/handle\/10915\/75047\" target=\"_blank\">Experiencia did\u00e1ctica mediada por TIC y elementos tradicionales para el estudio del movimiento circular<\/a>\n                        <\/div><div id=\"sedici-title\">Autores: <author><name><a href=http:\/\/sedici.unlp.edu.ar\/discover?filtertype=author&filter_relational_operator=equals&filter=Videla%2C%20Fabi\u00e1n%20Alfredo target=\"_blank\">Videla, Fabi\u00e1n Alfredo<\/a><\/name><\/author>-<author><name><a href=http:\/\/sedici.unlp.edu.ar\/discover?filtertype=author&filter_relational_operator=equals&filter=Torroba%2C%20Patricia%20Laura target=\"_blank\">Torroba, Patricia Laura<\/a><\/name><\/author>-<author><name><a href=http:\/\/sedici.unlp.edu.ar\/discover?filtertype=author&filter_relational_operator=equals&filter=Devece%2C%20Eugenio target=\"_blank\">Devece, Eugenio<\/a><\/name><\/author>-<author><name><a href=http:\/\/sedici.unlp.edu.ar\/discover?filtertype=author&filter_relational_operator=equals&filter=Aquilano%2C%20Luisina target=\"_blank\">Aquilano, Luisina<\/a><\/name><\/author><\/div><published>\n                                        <div id=\"sedici-title\">Fecha: <span class=\"sedici-content\">2020-04-07<\/span><\/div>\n                                    <\/published><dc:type>\n                                        <div id=\"sedici-title\">Tipo de documento: <span class=\"sedici-content\">Resumen<\/span><\/div>\n                                    <\/dc:type><summary> <div id=\"sedici-title\">Resumen:<span class=\"sedici-content\">En este trabajo se presenta una propuesta did\u00e1ctica implementada y evaluada para abordar conceptos ligados con la din\u00e1mica y cinem\u00e1tica circular. Como resultado de un an\u00e1lisis realizado sobre evaluaciones hechas en cursos introductorios de F\u00edsica I, los alumnos presentan en general, dificultades en apropiarse de los conceptos ligados al movimiento circular. Con el objetivo de favorecer el entendimiento de este movimiento, docentes de F\u00edsica I, han realizado actividades de dise\u00f1o y desarrollo de dispositivos did\u00e1cticos. En particular, en este trabajo, se propone emplear una serie de herramientas did\u00e1cticas utilizando TIC y otros materiales tradicionales, as\u00ed como simulaciones en el tratamiento de situaciones de din\u00e1mica circular con grado progresivo de complejidad y su posterior evaluaci\u00f3n.

These spatial inhomogeneous oscillating fields, employed to ionize and accelerate the electrons, result from the interaction between a pulsed low intensity laser and bow-tie shaped gold nanostructures. Under this excitation scheme, energy-resolved above-threshold ionization (ATI) photoelectron spectra have been simulated by solving the one-dimensional (1D) time-dependent Schr\u00f6dinger equation (TDSE) within the single active electron (SAE) approximation. These quantum mechanical results are supported by their classical counterparts, obtained by the numerical integration of the Newton\u2013Lorentz equation. By using near-infrared wavelengths (0.8\u20133 \u03bcm) sources, our results show that very high energetic electrons (with kinetic energies in the keV domain) can be generated, far exceeding the limits obtained by using conventional, spatially homogeneous fields. This new characteristic can be supported considering the non-recombining electrons trajectories, already reported by Neyra and coworkers (Neyra E, et al 2018 J. Opt. 20, 034002). In order to build a real representation of the spatial dependence of the plasmonic-enhanced field in an analytic function, we fit the generated \u2019actual\u2019 field using two Gaussian functions. We have further analyzed and explored this plasmonicmodified ATI phenomenon in a model argon atom by using several driven wavelengths at intensities in the order of 1014 W cm\u22122 . Throughout our contribution we carefully scrutinize the differences between the ATI obtained using spatially homogeneous and inhomogeneous laser fields. We present the various physical origins, or correspondingly distinct physical mechanisms, for the ATI generation driven by spatially bounded inhomogeneous fields.<\/span><\/div><\/summary><div class=\"a_unline\">Compartir: <a href=\"https:\/\/www.facebook.com\/sharer\/sharer.php?p[title]=Above-threshold ionization driven by few-cycle spatially bounded inhomogeneous laser fields&p[url]=http:\/\/sedici.unlp.edu.ar\/handle\/10915\/145966\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-facebook.png\" alt=\"Facebook logo\" title=\"Compartir en Facebook\">\n             <\/a>\n             <a href=\"https:\/\/twitter.com\/?status=Above-threshold ionization driven by few-cycle spatially bounded inhomogeneous laser fields http:\/\/sedici.unlp.edu.ar\/handle\/10915\/145966 via @sedici_unlp\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-twitter.png\" alt=\"Twitter logo\" title=\"Compartir en Twitter\"><\/a>\n             <a href=\"https:\/\/plus.google.com\/share?url=http:\/\/sedici.unlp.edu.ar\/handle\/10915\/145966\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-plus.png\" alt=\"Google+ logo\" title=\"Compartir en Google+\">\n             <\/a>\n             <a href=\"http:\/\/www.linkedin.com\/shareArticle?url=http:\/\/sedici.unlp.edu.ar\/handle\/10915\/145966\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-linkedin.png\" alt=\"Linkedin logo\" title=\"Compartir en Linkedin\">\n             <\/a>\n        <\/div><\/article><\/li><li><article>\n\t\t\t<title>Phenomenological studies of femtosecond laser ablation on optical thin films for integrated photonics<\/title>\n                        <div id=\"sedici-title\">\n                            <a href=\"http:\/\/sedici.unlp.edu.ar\/handle\/10915\/125083\" target=\"_blank\">Phenomenological studies of femtosecond laser ablation on optical thin films for integrated photonics<\/a>\n                        <\/div><div id=\"sedici-title\">Autores: <author><name><a href=http:\/\/sedici.unlp.edu.ar\/discover?filtertype=author&filter_relational_operator=equals&filter=Peyton%2C%20Roberto%20Ram\u00f3n target=\"_blank\">Peyton, Roberto Ram\u00f3n<\/a><\/name><\/author>-<author><name><a href=http:\/\/sedici.unlp.edu.ar\/discover?filtertype=author&filter_relational_operator=equals&filter=Guarepi%2C%20Valent\u00edn%20Luis target=\"_blank\">Guarepi, Valent\u00edn Luis<\/a><\/name><\/author>-<author><name><a href=http:\/\/sedici.unlp.edu.ar\/discover?filtertype=author&filter_relational_operator=equals&filter=Videla%2C%20Fabi\u00e1n%20Alfredo target=\"_blank\">Videla, Fabi\u00e1n Alfredo<\/a><\/name><\/author>-<author><name><a href=http:\/\/sedici.unlp.edu.ar\/discover?filtertype=author&filter_relational_operator=equals&filter=Torchia%2C%20Gustavo%20Adri\u00e1n target=\"_blank\">Torchia, Gustavo Adri\u00e1n<\/a><\/name><\/author><\/div><published>\n                                        <div id=\"sedici-title\">Fecha: <span class=\"sedici-content\">2020-01-01<\/span><\/div>\n                                    <\/published><dc:type>\n                                        <div id=\"sedici-title\">Tipo de documento: <span class=\"sedici-content\">Preprint<\/span><\/div>\n                                    <\/dc:type><summary> <div id=\"sedici-title\">Resumen:<span class=\"sedici-content\">In this work, we present a well-supported procedure to fabricate ridge optical waveguides onto thin films of PLZT by femtosecond laser ablation. To achieve smooth-guiding structures that guarantee good optical performance we have studied the characteristics of ablation threshold for different kinematic conditions of fs laser machining and we have also explored the different ablation regimens for several fluences reached. Furthermore, we characterized the morphology and roughness of ridge waveguides through a modal analysis of scattering loss for waveguides conducted by single and multiple scans. An innovative phenomenological model that describes the sidewall roughness to process parameters is proposed in this paper. With this approach, it is possible to extend the manufacturing method of smooth-guiding structures to many optical thin films by fs micromachining, so as to create integrated photonics devices that can be addressed to different technological applications.<\/span><\/div><\/summary><div class=\"a_unline\">Compartir: <a href=\"https:\/\/www.facebook.com\/sharer\/sharer.php?p[title]=Phenomenological studies of femtosecond laser ablation on optical thin films for integrated photonics&p[url]=http:\/\/sedici.unlp.edu.ar\/handle\/10915\/125083\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-facebook.png\" alt=\"Facebook logo\" title=\"Compartir en Facebook\">\n             <\/a>\n             <a href=\"https:\/\/twitter.com\/?status=Phenomenological studies of femtosecond laser ablation on optical thin films for integrated photonics http:\/\/sedici.unlp.edu.ar\/handle\/10915\/125083 via @sedici_unlp\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-twitter.png\" alt=\"Twitter logo\" title=\"Compartir en Twitter\"><\/a>\n             <a href=\"https:\/\/plus.google.com\/share?url=http:\/\/sedici.unlp.edu.ar\/handle\/10915\/125083\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-plus.png\" alt=\"Google+ logo\" title=\"Compartir en Google+\">\n             <\/a>\n             <a href=\"http:\/\/www.linkedin.com\/shareArticle?url=http:\/\/sedici.unlp.edu.ar\/handle\/10915\/125083\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-linkedin.png\" alt=\"Linkedin logo\" title=\"Compartir en Linkedin\">\n             <\/a>\n        <\/div><\/article><\/li><li><article>\n\t\t\t<title>Desarrollo de experiencias para la ense\u00f1anza y difusi\u00f3n de la \u00d3ptica con impresi\u00f3n 3D<\/title>\n                        <div id=\"sedici-title\">\n                            <a href=\"http:\/\/sedici.unlp.edu.ar\/handle\/10915\/135331\" target=\"_blank\">Desarrollo de experiencias para la ense\u00f1anza y difusi\u00f3n de la \u00d3ptica con impresi\u00f3n 3D<\/a>\n                        <\/div><div id=\"sedici-title\">Autores: <author><name><a href=http:\/\/sedici.unlp.edu.ar\/discover?filtertype=author&filter_relational_operator=equals&filter=Peyton%2C%20Roberto%20Ram\u00f3n target=\"_blank\">Peyton, Roberto Ram\u00f3n<\/a><\/name><\/author>-<author><name><a href=http:\/\/sedici.unlp.edu.ar\/discover?filtertype=author&filter_relational_operator=equals&filter=Presti%2C%20Dami\u00e1n%20A. target=\"_blank\">Presti, Dami\u00e1n A.<\/a><\/name><\/author>-<author><name><a href=http:\/\/sedici.unlp.edu.ar\/discover?filtertype=author&filter_relational_operator=equals&filter=Mart\u00ednez%20Valdiviezo%2C%20Jeffry%20H. target=\"_blank\">Mart\u00ednez Valdiviezo, Jeffry H.<\/a><\/name><\/author>-<author><name><a href=http:\/\/sedici.unlp.edu.ar\/discover?filtertype=author&filter_relational_operator=equals&filter=Videla%2C%20Fabi\u00e1n%20Alfredo target=\"_blank\">Videla, Fabi\u00e1n Alfredo<\/a><\/name><\/author>-<author><name><a href=http:\/\/sedici.unlp.edu.ar\/discover?filtertype=author&filter_relational_operator=equals&filter=Torchia%2C%20Gustavo%20Adri\u00e1n target=\"_blank\">Torchia, Gustavo Adri\u00e1n<\/a><\/name><\/author><\/div><published>\n                                        <div id=\"sedici-title\">Fecha: <span class=\"sedici-content\">2020-01-01<\/span><\/div>\n                                    <\/published><dc:type>\n                                        <div id=\"sedici-title\">Tipo de documento: <span class=\"sedici-content\">Objeto de conferencia<\/span><\/div>\n                                    <\/dc:type><summary> <div id=\"sedici-title\">Resumen:<span class=\"sedici-content\">En este trabajo se presentan tres experiencias desarrolladas con la tecnolog\u00eda de impresi\u00f3n 3D para la ense\u00f1anza y difusi\u00f3n de la \u00d3ptica.

La documentaci\u00f3n necesaria para llevar a cabo las practicas, gu\u00edas experimentales, modelos 3D y manuales de armado, se encuentran disponibles en un espacio web de acceso libre y gratuito. El uso de la impresi\u00f3n 3D es un recurso tecnol\u00f3gico apropiado para desarrollar nuevas aptitudes en el proceso de aprendizaje y criterios pedag\u00f3gicos. Por otra parte la realizaci\u00f3n de experiencias de laboratorio desarrolla actitudes inclusivas, desde un enfoque participativo.

These activities were planned, designed, and implemented to go deeper into knowledge about light polarization, reflection and refraction phenomena, and colour perception. The planning methodology is also detailed, in particular, the design and description of the activity. Experimental guides, 3D models and assembly manuals are available in a free and freely accessible web space.\r\nIn summary, we demonstrate that the 3D printing can be used as a technological, inclusive and pedagogical resource for teaching.

We will show that it is possible to calibrate, in relative form, a scale ofwavelength, to determine, accurately enough, a thermally induced laser detuning, using the free spectral range of an OFRR. The optical circuit was constructed using 2 \u00d7 2 (50\/50) optical fiber coupler obtaining an OFRR of10-cm ring radius. A single-mode diode laser system has been launched into the OFRR, and different experiments have been performed. We tested the OFRR performance, considering fluctuations in the laser wavelengthcaused by small temperature instabilities, measuring the output intensity from the ring resonator. Theoretical simulations and experimental results were in agreement with the expected behavior. Furthermore, OFRR systemscan be used as an excellent control tool to test the wavelength stability for a narrowband laser diode and act as a part of a control system.<\/span><\/div><\/summary><div class=\"a_unline\">Compartir: <a href=\"https:\/\/www.facebook.com\/sharer\/sharer.php?p[title]=Optical fiber ring resonator as a high-resolution spectrometer: characterization and applications with single line diode lasers&p[url]=http:\/\/sedici.unlp.edu.ar\/handle\/10915\/97243\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-facebook.png\" alt=\"Facebook logo\" title=\"Compartir en Facebook\">\n             <\/a>\n             <a href=\"https:\/\/twitter.com\/?status=Optical fiber ring resonator as a high-resolution spectrometer: characterization and applications with single line diode lasers http:\/\/sedici.unlp.edu.ar\/handle\/10915\/97243 via @sedici_unlp\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-twitter.png\" alt=\"Twitter logo\" title=\"Compartir en Twitter\"><\/a>\n             <a href=\"https:\/\/plus.google.com\/share?url=http:\/\/sedici.unlp.edu.ar\/handle\/10915\/97243\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-plus.png\" alt=\"Google+ logo\" title=\"Compartir en Google+\">\n             <\/a>\n             <a href=\"http:\/\/www.linkedin.com\/shareArticle?url=http:\/\/sedici.unlp.edu.ar\/handle\/10915\/97243\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-linkedin.png\" alt=\"Linkedin logo\" title=\"Compartir en Linkedin\">\n             <\/a>\n        <\/div><\/article><\/li><li><article>\n\t\t\t<title>Aplicaciones tecnol\u00f3gicas inspiradas en el dispositivo de Venturi: Un pretexto para visitar la ecuaci\u00f3n de Bernoulli<\/title>\n                        <div id=\"sedici-title\">\n                            <a href=\"http:\/\/sedici.unlp.edu.ar\/handle\/10915\/154068\" target=\"_blank\">Aplicaciones tecnol\u00f3gicas inspiradas en el dispositivo de Venturi: Un pretexto para visitar la ecuaci\u00f3n de Bernoulli<\/a>\n                        <\/div><div id=\"sedici-title\">Autores: <author><name><a href=http:\/\/sedici.unlp.edu.ar\/discover?filtertype=author&filter_relational_operator=equals&filter=Videla%2C%20Fabi\u00e1n%20Alfredo target=\"_blank\">Videla, Fabi\u00e1n Alfredo<\/a><\/name><\/author>-<author><name><a href=http:\/\/sedici.unlp.edu.ar\/discover?filtertype=author&filter_relational_operator=equals&filter=Torroba%2C%20Patricia%20Laura target=\"_blank\">Torroba, Patricia Laura<\/a><\/name><\/author>-<author><name><a href=http:\/\/sedici.unlp.edu.ar\/discover?filtertype=author&filter_relational_operator=equals&filter=Devece%2C%20Eugenio target=\"_blank\">Devece, Eugenio<\/a><\/name><\/author>-<author><name><a href=http:\/\/sedici.unlp.edu.ar\/discover?filtertype=author&filter_relational_operator=equals&filter=Aquilano%2C%20Luisina target=\"_blank\">Aquilano, Luisina<\/a><\/name><\/author><\/div><published>\n                                        <div id=\"sedici-title\">Fecha: <span class=\"sedici-content\">2018-01-01<\/span><\/div>\n                                    <\/published><dc:type>\n                                        <div id=\"sedici-title\">Tipo de documento: <span class=\"sedici-content\">Objeto de conferencia<\/span><\/div>\n                                    <\/dc:type><summary> <div id=\"sedici-title\">Resumen:<span class=\"sedici-content\">Muchos dispositivos industriales aplican el dispositivo de Venturi, as\u00ed, su comprensi\u00f3n desde el punto de vista f\u00edsico resulta indispensable como saber b\u00e1sico en las carreas de ingenier\u00eda. En este trabajo se han recopilado algunas de las dificultades habituales experimentadas por los alumnos a la hora de resolver situaciones que pueden modelarse aplicando la ecuaci\u00f3n de Bernoulli. Para fundamentar este abordaje, se presenta el marco te\u00f3rico indispensable para precisar las variables puestas en juego y su relaci\u00f3n. Las predicciones efectuadas en este marco sobre el comportamiento del dispositivo se reinterpretar\u00e1n en la clase incorporando mostraciones basadas en equipos de desarrollo local y un software de simulaci\u00f3n libre. Para motivar a los alumnos se ejemplificaron variados usos de los dispositivos de Venturi mostrando la atrayente oferta de soluciones aplicadas en el \u00e1mbito industrial. La evaluaci\u00f3n de un problema convencional permiti\u00f3 analizar su desempe\u00f1o apreci\u00e1ndose mejoras respecto de aquellos alumnos que no recibieron este tratamiento del tema. No obstante, surgen dudas sobre si las soluciones planteadas son acertadas fruto de su comprensi\u00f3n sobre la f\u00edsica involucrada o de un manejo mec\u00e1nico de las ecuaciones. Para superar esta incertidumbre se propone una evaluaci\u00f3n con situaciones que ponen en juego conocimientos m\u00e1s conceptuales.\n\nMany industrial devices apply the Venturi device, thus, its understanding from the physical point of view is indispensable as basic knowledge in engineering tasks. In this paper we have compiled some of the habitual difficulties experienced by students when solving situations that can be modeled by applying the Bernoulli equation. In order to support this approach, the indispensable theoretical framework is presented to specify the variables put into play and their relationship. The predictions made in this framework on the behavior of the device will be reinterpreted in the class incorporating demonstrations based on local development equipment and free simulation software. To motivate the students, various uses of Venturi devices were exemplified by showing the attractive offer of solutions applied in the industrial field. The evaluation of a conventional problem allowed to analyze its performance, appreciating improvements with respect to those students who did not receive this treatment of the topic. Even so, doubts arise as to whether the proposed solutions are correct due to their understanding of the physics involved or of the mechanical handling of the equations. To overcome this uncertainty, an evaluation is proposed with situations that put into play more conceptual knowledge.<\/span><\/div><\/summary><div class=\"a_unline\">Compartir: <a href=\"https:\/\/www.facebook.com\/sharer\/sharer.php?p[title]=Aplicaciones tecnol\u00f3gicas inspiradas en el dispositivo de Venturi: Un pretexto para visitar la ecuaci\u00f3n de Bernoulli&p[url]=http:\/\/sedici.unlp.edu.ar\/handle\/10915\/154068\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-facebook.png\" alt=\"Facebook logo\" title=\"Compartir en Facebook\">\n             <\/a>\n             <a href=\"https:\/\/twitter.com\/?status=Aplicaciones tecnol\u00f3gicas inspiradas en el dispositivo de Venturi: Un pretexto para visitar la ecuaci\u00f3n de Bernoulli http:\/\/sedici.unlp.edu.ar\/handle\/10915\/154068 via @sedici_unlp\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-twitter.png\" alt=\"Twitter logo\" title=\"Compartir en Twitter\"><\/a>\n             <a href=\"https:\/\/plus.google.com\/share?url=http:\/\/sedici.unlp.edu.ar\/handle\/10915\/154068\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-plus.png\" alt=\"Google+ logo\" title=\"Compartir en Google+\">\n             <\/a>\n             <a href=\"http:\/\/www.linkedin.com\/shareArticle?url=http:\/\/sedici.unlp.edu.ar\/handle\/10915\/154068\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-linkedin.png\" alt=\"Linkedin logo\" title=\"Compartir en Linkedin\">\n             <\/a>\n        <\/div><\/article><\/li><li><article>\n\t\t\t<title>Movimiento circular: una propuesta did\u00e1ctica mediada por TIC basada en mostraciones y simulaciones<\/title>\n                        <div id=\"sedici-title\">\n                            <a href=\"http:\/\/sedici.unlp.edu.ar\/handle\/10915\/121834\" target=\"_blank\">Movimiento circular: una propuesta did\u00e1ctica mediada por TIC basada en mostraciones y simulaciones<\/a>\n                        <\/div><div id=\"sedici-title\">Autores: <author><name><a href=http:\/\/sedici.unlp.edu.ar\/discover?filtertype=author&filter_relational_operator=equals&filter=Devece%2C%20Eugenio target=\"_blank\">Devece, Eugenio<\/a><\/name><\/author>-<author><name><a href=http:\/\/sedici.unlp.edu.ar\/discover?filtertype=author&filter_relational_operator=equals&filter=Torroba%2C%20Patricia%20Laura target=\"_blank\">Torroba, Patricia Laura<\/a><\/name><\/author>-<author><name><a href=http:\/\/sedici.unlp.edu.ar\/discover?filtertype=author&filter_relational_operator=equals&filter=Videla%2C%20Fabi\u00e1n%20Alfredo target=\"_blank\">Videla, Fabi\u00e1n Alfredo<\/a><\/name><\/author>-<author><name><a href=http:\/\/sedici.unlp.edu.ar\/discover?filtertype=author&filter_relational_operator=equals&filter=Aquilano%2C%20Luisina target=\"_blank\">Aquilano, Luisina<\/a><\/name><\/author><\/div><published>\n                                        <div id=\"sedici-title\">Fecha: <span class=\"sedici-content\">2018-01-01<\/span><\/div>\n                                    <\/published><dc:type>\n                                        <div id=\"sedici-title\">Tipo de documento: <span class=\"sedici-content\">Objeto de conferencia<\/span><\/div>\n                                    <\/dc:type><summary> <div id=\"sedici-title\">Resumen:<span class=\"sedici-content\">En este trabajo se presenta una serie de herramientas did\u00e1cticas con grado progresivo de complejidad enfocadas en el estudio del movimiento circular. En el estudio de este movimiento se pueden identificar algunas causas elementales que generan conceptos equivocados. Entre ellas podemos identificar: Dificultades en el empleo del lenguaje (fuerza centr\u00edfuga, fuerza centr\u00edpeta), dificultades en la comprensi\u00f3n del abordaje matem\u00e1tico de la situaci\u00f3n ya que se incorporan operaciones vectoriales y en consecuencia representaci\u00f3n de las variables en 3 dimensiones, dificultades en la comprensi\u00f3n de la f\u00edsica aplicada para la resoluci\u00f3n del problema (identificaci\u00f3n de los agentes actuantes).\r\nLuego de haber discutido el modelo que describe el movimiento circular se pondr\u00e1n en juego el grado de comprensi\u00f3n del tema a trav\u00e9s de mostraciones con grado de complejidad creciente. Estas mostraciones se realizan con dispositivos dise\u00f1ados en la c\u00e1tedra de f\u00e1cil adquisici\u00f3n en el mercado local, obteniendo las magnitudes m\u00e1s relevantes a trav\u00e9s de TIC.

Se propone una tarea de articulaci\u00f3n de actividades te\u00f3rico-pr\u00e1cticas-experimentales que contempla metodolog\u00edas y contenidos, para favorecer la adquisici\u00f3n de actitudes, aptitudes y competencias requeridas en la formaci\u00f3n integral del futuro profesional de la ingenier\u00eda. La experiencia se desarrolla en el aula y consiste en liberar dos cuerpos desde la parte superior de un plano inclinado, (un cilindro y un aro, ambos tienen igual masa y radio). Previamente, a la realizaci\u00f3n de la pr\u00e1ctica, se les pide a los alumnos que hagan una predicci\u00f3n sobre cu\u00e1l de los dos cuerpos suponen que llega primero a la base del plano. Se trabaja en peque\u00f1os grupos de alumnos, generando la discusi\u00f3n entre pares y ejercitando habilidades como la observaci\u00f3n, la elaboraci\u00f3n de hip\u00f3tesis y la adquisici\u00f3n de criterios para su validaci\u00f3n. Se realiza la experiencia y se contrasta el resultado experimental con las predicciones realizadas. Los estudiantes deben justificar el resultado de la experiencia modelando correctamente el sistema f\u00edsico y con el uso de las leyes de Newton. Como resultado del an\u00e1lisis obtienen las aceleraciones de los cuerpos y de qu\u00e9 variables dependen. Se incluye en el tratamiento una comparaci\u00f3n entre el modelo de cuerpo r\u00edgido y el de part\u00edcula, desde el punto de vista te\u00f3rico y experimental con el empleo de sensores de posici\u00f3n. La toma de datos en tiempo real favorece la validaci\u00f3n que el an\u00e1lisis te\u00f3rico predice sobre el comportamiento de un sistema. A continuaci\u00f3n se utiliza un video de la experiencia realizada y con el uso del software Logger-Pro se obtiene una representaci\u00f3n de la posici\u00f3n del cuerpo en funci\u00f3n del tiempo. A partir de \u00e9sta, se obtiene la aceleraci\u00f3n y puede ser contrastada en cada situaci\u00f3n, permitiendo validar el modelo f\u00edsico y reforzar los conceptos involucrados en el tema. En esta experiencia se busca incentivar al estudiante para que desarrolle competencias tales como: el trabajo colaborativo, la interpretaci\u00f3n de gr\u00e1ficos, la identificaci\u00f3n de las variables relevantes, el tratamiento de incertezas. El an\u00e1lisis de estas situaciones se completa con una reflexi\u00f3n sobre los l\u00edmites de validez de las expresiones operativas utilizadas y la necesidad de expresar claramente las aproximaciones y suposiciones que se realizan en el momento en que los estudiantes resuelven problemas pr\u00e1cticos o de laboratorio. Las actividades formativas articuladas, se ven reflejadas en los resultados positivos de las evaluaciones de acreditaci\u00f3n del curso y en las encuestas realizadas.<\/span><\/div><\/summary><div class=\"a_unline\">Compartir: <a href=\"https:\/\/www.facebook.com\/sharer\/sharer.php?p[title]=Tratamiento del movimiento de rototraslaci\u00f3n de un cuerpo r\u00edgido haciendo uso integrado de TIC\u00b4s y elementos tradicionales&p[url]=http:\/\/sedici.unlp.edu.ar\/handle\/10915\/136383\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-facebook.png\" alt=\"Facebook logo\" title=\"Compartir en Facebook\">\n             <\/a>\n             <a href=\"https:\/\/twitter.com\/?status=Tratamiento del movimiento de rototraslaci\u00f3n de un cuerpo r\u00edgido haciendo uso integrado de TIC\u00b4s y elementos tradicionales http:\/\/sedici.unlp.edu.ar\/handle\/10915\/136383 via @sedici_unlp\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-twitter.png\" alt=\"Twitter logo\" title=\"Compartir en Twitter\"><\/a>\n             <a href=\"https:\/\/plus.google.com\/share?url=http:\/\/sedici.unlp.edu.ar\/handle\/10915\/136383\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-plus.png\" alt=\"Google+ logo\" title=\"Compartir en Google+\">\n             <\/a>\n             <a href=\"http:\/\/www.linkedin.com\/shareArticle?url=http:\/\/sedici.unlp.edu.ar\/handle\/10915\/136383\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-linkedin.png\" alt=\"Linkedin logo\" title=\"Compartir en Linkedin\">\n             <\/a>\n        <\/div><\/article><\/li><li><article>\n\t\t\t<title>El uso de videojuegos en un laboratorio de F\u00edsica<\/title>\n                        <div id=\"sedici-title\">\n                            <a href=\"http:\/\/sedici.unlp.edu.ar\/handle\/10915\/37778\" target=\"_blank\">El uso de videojuegos en un laboratorio de F\u00edsica<\/a>\n                        <\/div><div id=\"sedici-title\">Autores: <author><name><a href=http:\/\/sedici.unlp.edu.ar\/discover?filtertype=author&filter_relational_operator=equals&filter=Gallego%20Sagastume%2C%20Juana%20In\u00e9s target=\"_blank\">Gallego Sagastume, Juana In\u00e9s<\/a><\/name><\/author>-<author><name><a href=http:\/\/sedici.unlp.edu.ar\/discover?filtertype=author&filter_relational_operator=equals&filter=Devece%2C%20Eugenio target=\"_blank\">Devece, Eugenio<\/a><\/name><\/author>-<author><name><a href=http:\/\/sedici.unlp.edu.ar\/discover?filtertype=author&filter_relational_operator=equals&filter=Torroba%2C%20Patricia%20Laura target=\"_blank\">Torroba, Patricia Laura<\/a><\/name><\/author>-<author><name><a href=http:\/\/sedici.unlp.edu.ar\/discover?filtertype=author&filter_relational_operator=equals&filter=Videla%2C%20Fabi\u00e1n%20Alfredo target=\"_blank\">Videla, Fabi\u00e1n Alfredo<\/a><\/name><\/author><\/div><published>\n                                        <div id=\"sedici-title\">Fecha: <span class=\"sedici-content\">2013-01-01<\/span><\/div>\n                                    <\/published><dc:type>\n                                        <div id=\"sedici-title\">Tipo de documento: <span class=\"sedici-content\">Objeto de conferencia<\/span><\/div>\n                                    <\/dc:type><summary> <div id=\"sedici-title\">Resumen:<span class=\"sedici-content\">En las clases de la C\u00e1tedra de F\u00edsica I de la Facultad de Ingenier\u00eda, UNLP, se utilizan con frecuencia videos y TIC's, para ilustrar fen\u00f3menos f\u00edsicos y las leyes que los rigen.

In particular, their optical properties are governed by the characteristics of the dielectric function of the metal, its size and environment. This work analyses the separated contribution of free and bound electrons on the optical properties of copper Nps. Usually, the contribution of free electrons to the dielectric function is corrected for particle size through the modification of the damping constant, which is changed as usual introducing a term inversely proportional to the particle\u2019s radius to account for the extra collisions with the boundary when the size approaches the electronic mean free path limit (about 10 nm). For bound electron contribution, the interband transitions from the d-band to the conduction band are considered together with the fact that the electronic density of states in the conduction band must be made size-dependent to account for the larger spacing between electronic energy levels as the particle decreases in size below 2 nm. Taking into account these specific modifications of free and bound electron contributions to the dielectric function, it was possible to fit the bulk complex dielectric function, and consequently, determine optical parameters and band energy values such as the coefficient for bound electron contribution Qbulk = 2 \u00d7 1024, gap energy Eg = 1.95 eV, Fermi energy EF = 2.15 eV, and damping constant for bound electrons \u03b3b = 1.15 \u00d7 1014 Hz. With both size-dependent contributions to the dielectric function, extinction spectra of copper Nps in the subnanometer radius range can be calculated using Mie\u2019s theory and its behaviour with size can be analysed. These studies are applied to fit experimental extinction spectra of very small spherical core\u2013shell Cu\u2013Cu2O Nps generated by ultrafast laser ablation of a solid target in water. Theoretical calculations for subnanometric core radius are in excellent agreement with experimental results obtained from core\u2013shell colloidal Nps. From the fitting, it is possible determining core radius and shell thickness of the Nps, showing that optical extinction spectroscopy is a good complementary technique to standard high-resolution electron microscopy for sizing spherical nanometric-subnanometric Nps.<\/span><\/div><\/summary><div class=\"a_unline\">Compartir: <a href=\"https:\/\/www.facebook.com\/sharer\/sharer.php?p[title]=Plasmon Spectroscopy for Subnanometric Copper Particles: Dielectric Function and Core\u2013Shell Sizing&p[url]=http:\/\/sedici.unlp.edu.ar\/handle\/10915\/144996\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-facebook.png\" alt=\"Facebook logo\" title=\"Compartir en Facebook\">\n             <\/a>\n             <a href=\"https:\/\/twitter.com\/?status=Plasmon Spectroscopy for Subnanometric Copper Particles: Dielectric Function and Core\u2013Shell Sizing http:\/\/sedici.unlp.edu.ar\/handle\/10915\/144996 via @sedici_unlp\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-twitter.png\" alt=\"Twitter logo\" title=\"Compartir en Twitter\"><\/a>\n             <a href=\"https:\/\/plus.google.com\/share?url=http:\/\/sedici.unlp.edu.ar\/handle\/10915\/144996\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-plus.png\" alt=\"Google+ logo\" title=\"Compartir en Google+\">\n             <\/a>\n             <a href=\"http:\/\/www.linkedin.com\/shareArticle?url=http:\/\/sedici.unlp.edu.ar\/handle\/10915\/144996\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-linkedin.png\" alt=\"Linkedin logo\" title=\"Compartir en Linkedin\">\n             <\/a>\n        <\/div><\/article><\/li><li><article>\n\t\t\t<title>Analysis of Winds Affecting Air Pollutant Transport at La Plata, Argentina<\/title>\n                        <div id=\"sedici-title\">\n                            <a href=\"http:\/\/sedici.unlp.edu.ar\/handle\/10915\/119271\" target=\"_blank\">Analysis of Winds Affecting Air Pollutant Transport at La Plata, Argentina<\/a>\n                        <\/div><div id=\"sedici-title\">Autores: <author><name><a href=http:\/\/sedici.unlp.edu.ar\/discover?filtertype=author&filter_relational_operator=equals&filter=Ratto%2C%20Gustavo target=\"_blank\">Ratto, Gustavo<\/a><\/name><\/author>-<author><name><a href=http:\/\/sedici.unlp.edu.ar\/discover?filtertype=author&filter_relational_operator=equals&filter=Maronna%2C%20Ricardo%20Antonio target=\"_blank\">Maronna, Ricardo Antonio<\/a><\/name><\/author>-<author><name><a href=http:\/\/sedici.unlp.edu.ar\/discover?filtertype=author&filter_relational_operator=equals&filter=Repossi%2C%20Patricia target=\"_blank\">Repossi, Patricia<\/a><\/name><\/author>-<author><name><a href=http:\/\/sedici.unlp.edu.ar\/discover?filtertype=author&filter_relational_operator=equals&filter=Videla%2C%20Fabi\u00e1n%20Alfredo target=\"_blank\">Videla, Fabi\u00e1n Alfredo<\/a><\/name><\/author>-<author><name><a href=http:\/\/sedici.unlp.edu.ar\/discover?filtertype=author&filter_relational_operator=equals&filter=Nico%2C%20Andr\u00e9s target=\"_blank\">Nico, Andr\u00e9s<\/a><\/name><\/author>-<author><name><a href=http:\/\/sedici.unlp.edu.ar\/discover?filtertype=author&filter_relational_operator=equals&filter=Reyna%20Almandos%2C%20Jorge%20Guillermo target=\"_blank\">Reyna Almandos, Jorge Guillermo<\/a><\/name><\/author><\/div><published>\n                                        <div id=\"sedici-title\">Fecha: <span class=\"sedici-content\">2012-01-01<\/span><\/div>\n                                    <\/published><dc:type>\n                                        <div id=\"sedici-title\">Tipo de documento: <span class=\"sedici-content\">Articulo<\/span><\/div>\n                                    <\/dc:type><summary> <div id=\"sedici-title\">Resumen:<span class=\"sedici-content\">An hourly wind analysis for the populated area of La Plata city (with high industrial, power station and vehicular activi-ties) is presented and discussed. Euclidean distance and minimum covariance determinant (a robust correlation coeffi-cient) are employed, as similarity approaches, in order to compare observed wind direction frequency patterns at two monitoring sites during 1998-2003. A preliminary assessment of two sectors, namely Sector 1 (NNW-N-NNE-NE) and Sector 2 (ENE-E-ESE), relevant for the transport of industrial air pollutants towards population exposed, is discussed taking variances into account and employing a locally weighted smoothing approach (LOESS). Both similarity ap-proaches allowed gain insight of wind patterns. The distance approach showed good similarity between sites while the correlation approach showed an uneven picture depending on the wind direction. Most of the differences are explained in terms of the sea-land breeze effect but also differences in terrain roughness and data quality are taken into account. Winds from sectors 1 or 2 (analyzed during 1998-2009) may occur more than 50% of the time, most of the differences regarding the influence of the day and the season on these sectors are attributable to sea-land breeze phenomena. The LOESS proved to be appropriate to analyze the stability with time of both sectors and to discard possible remaining patterns; results are in accordance with studies that assess the interannual variability for different variables in La Plata river area. The robust correlation coefficient revealed, as an example, the linear character of dependence between winds from sector 2 and sulfur dioxide concentrations. Wind velocities and calms are also discussed.<\/span><\/div><\/summary><div class=\"a_unline\">Compartir: <a href=\"https:\/\/www.facebook.com\/sharer\/sharer.php?p[title]=Analysis of Winds Affecting Air Pollutant Transport at La Plata, Argentina&p[url]=http:\/\/sedici.unlp.edu.ar\/handle\/10915\/119271\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-facebook.png\" alt=\"Facebook logo\" title=\"Compartir en Facebook\">\n             <\/a>\n             <a href=\"https:\/\/twitter.com\/?status=Analysis of Winds Affecting Air Pollutant Transport at La Plata, Argentina http:\/\/sedici.unlp.edu.ar\/handle\/10915\/119271 via @sedici_unlp\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-twitter.png\" alt=\"Twitter logo\" title=\"Compartir en Twitter\"><\/a>\n             <a href=\"https:\/\/plus.google.com\/share?url=http:\/\/sedici.unlp.edu.ar\/handle\/10915\/119271\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-plus.png\" alt=\"Google+ logo\" title=\"Compartir en Google+\">\n             <\/a>\n             <a href=\"http:\/\/www.linkedin.com\/shareArticle?url=http:\/\/sedici.unlp.edu.ar\/handle\/10915\/119271\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-linkedin.png\" alt=\"Linkedin logo\" title=\"Compartir en Linkedin\">\n             <\/a>\n        <\/div><\/article><\/li><li><article>\n\t\t\t<title>Calm analysis using a robust method<\/title>\n                        <div id=\"sedici-title\">\n                            <a href=\"http:\/\/sedici.unlp.edu.ar\/handle\/10915\/136816\" target=\"_blank\">Calm analysis using a robust method<\/a>\n                        <\/div><div id=\"sedici-title\">Autores: <author><name><a href=http:\/\/sedici.unlp.edu.ar\/discover?filtertype=author&filter_relational_operator=equals&filter=Ratto%2C%20Gustavo target=\"_blank\">Ratto, Gustavo<\/a><\/name><\/author>-<author><name><a href=http:\/\/sedici.unlp.edu.ar\/discover?filtertype=author&filter_relational_operator=equals&filter=Videla%2C%20Fabi\u00e1n%20Alfredo target=\"_blank\">Videla, Fabi\u00e1n Alfredo<\/a><\/name><\/author>-<author><name><a href=http:\/\/sedici.unlp.edu.ar\/discover?filtertype=author&filter_relational_operator=equals&filter=Maronna%2C%20Ricardo%20Antonio target=\"_blank\">Maronna, Ricardo Antonio<\/a><\/name><\/author>-<author><name><a href=http:\/\/sedici.unlp.edu.ar\/discover?filtertype=author&filter_relational_operator=equals&filter=Reyna%20Almandos%2C%20Jorge%20Guillermo target=\"_blank\">Reyna Almandos, Jorge Guillermo<\/a><\/name><\/author><\/div><published>\n                                        <div id=\"sedici-title\">Fecha: <span class=\"sedici-content\">2012-01-01<\/span><\/div>\n                                    <\/published><dc:type>\n                                        <div id=\"sedici-title\">Tipo de documento: <span class=\"sedici-content\">Objeto de conferencia<\/span><\/div>\n                                    <\/dc:type><summary> <div id=\"sedici-title\">Resumen:<span class=\"sedici-content\">La Plata city and surroundings (Argentina) -around 800 000 inhabitants- possesses high industrial activity and intense vehicular traffic but there is no governmental air pollution network and basic meteorological parameters have been scarcely studied. This paper focuses on wind calm structure and wind patterns after the end of calms in order to assess the potential accumulation and fate of released airborne pollutants. A robust correlation method using an M-estimator is employed to compare seasonal observations at three monitoring sites located in key parts of the city covering 1995- 2006. Results show that calms are on average 14.7% in summer, 19.1% in autumn, 12.8% in winter and 11.6% in spring. The three sites under study were highly correlated indicating a generalized calm pattern for the city and surroundings. The robust coefficient allows inferring the lineal character of dependence among observations at the three sites. Calm structure revealed that approximately 50.6 % of the calms lasted 1 hour while calms lasting 5 hours or less constitute around 90% of calm occurrences. Calms lasting two hours or more are more probably to occur during wee and evening hours indicating when the accumulation of released air pollutants is likely to happen. Wind roses named \"outgoing of calm wind roses\" (time consuming to estimate) showed the wind direction patterns more probable to occur after a calm. Overall correlations between seasonal averaged wind roses and those corresponding to the outgoing of calms showed strong linear correlation for all the seasons. This allows concluding that winds after calms may be well represented by their corresponding seasonal averaged patterns (easy to compute).<\/span><\/div><\/summary><div class=\"a_unline\">Compartir: <a href=\"https:\/\/www.facebook.com\/sharer\/sharer.php?p[title]=Calm analysis using a robust method&p[url]=http:\/\/sedici.unlp.edu.ar\/handle\/10915\/136816\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-facebook.png\" alt=\"Facebook logo\" title=\"Compartir en Facebook\">\n             <\/a>\n             <a href=\"https:\/\/twitter.com\/?status=Calm analysis using a robust method http:\/\/sedici.unlp.edu.ar\/handle\/10915\/136816 via @sedici_unlp\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-twitter.png\" alt=\"Twitter logo\" title=\"Compartir en Twitter\"><\/a>\n             <a href=\"https:\/\/plus.google.com\/share?url=http:\/\/sedici.unlp.edu.ar\/handle\/10915\/136816\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-plus.png\" alt=\"Google+ logo\" title=\"Compartir en Google+\">\n             <\/a>\n             <a href=\"http:\/\/www.linkedin.com\/shareArticle?url=http:\/\/sedici.unlp.edu.ar\/handle\/10915\/136816\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-linkedin.png\" alt=\"Linkedin logo\" title=\"Compartir en Linkedin\">\n             <\/a>\n        <\/div><\/article><\/li><li><article>\n\t\t\t<title>Desarrollo de t\u00e9cnicas de espectroscop\u00eda de scattering \u00f3ptico y de resonancia plasm\u00f3nica para la determinaci\u00f3n de tama\u00f1o de micro y nanopart\u00edculas<\/title>\n                        <div id=\"sedici-title\">\n                            <a href=\"http:\/\/sedici.unlp.edu.ar\/handle\/10915\/18185\" target=\"_blank\">Desarrollo de t\u00e9cnicas de espectroscop\u00eda de scattering \u00f3ptico y de resonancia plasm\u00f3nica para la determinaci\u00f3n de tama\u00f1o de micro y nanopart\u00edculas<\/a>\n                        <\/div><div id=\"sedici-title\">Autores: <author><name><a href=http:\/\/sedici.unlp.edu.ar\/discover?filtertype=author&filter_relational_operator=equals&filter=Videla%2C%20Fabi\u00e1n%20Alfredo target=\"_blank\">Videla, Fabi\u00e1n Alfredo<\/a><\/name><\/author><\/div><published>\n                                        <div id=\"sedici-title\">Fecha: <span class=\"sedici-content\">2011-01-01<\/span><\/div>\n                                    <\/published><dc:type>\n                                        <div id=\"sedici-title\">Tipo de documento: <span class=\"sedici-content\">Tesis de doctorado<\/span><\/div>\n                                    <\/dc:type><summary> <div id=\"sedici-title\">Resumen:<span class=\"sedici-content\">Esta tesis trata fundamentalmente sobre el desarrollo de t\u00e9cnicas \u00f3pticas \u00fatiles en la determinaci\u00f3n del tama\u00f1o de part\u00edculas tanto diel\u00e9ctricas en el rango microm\u00e9trico como met\u00e1licas en el rango nanom\u00e9trico. Dichas t\u00e9cnicas est\u00e1n basadas en el an\u00e1lisis espectrosc\u00f3pico de la radiaci\u00f3n interactuante con el material particulado. Para el caso de part\u00edculas diel\u00e9ctricas se implement\u00f3 la llamada espectroscop\u00eda de retrodispersi\u00f3n, mientras que para part\u00edculas met\u00e1licas se recurre a la espectroscop\u00eda de resonancia de plasmones. Las propiedades de las nanopart\u00edculas se diferencian notablemente de su comportamiento como material volum\u00e9trico (bulk). La Ingenier\u00eda y la F\u00edsica Aplicada est\u00e1n trabajando actualmente en forma interdisciplinaria para el estudio y desarrollo de materiales nanoestructurados con propiedades novedosas que puedan ser dise\u00f1ados y funcionalizados para aplicaciones espec\u00edficas. Se han obtenido resultados empleado la transformada de Fourier para la determinaci\u00f3n de tama\u00f1o de part\u00edculas diel\u00e9ctricas en suspensiones mono y multimodales resultando un m\u00e9todo relativamente sencillo. El rango de tama\u00f1os de part\u00edculas abarcado ha sido desde el micr\u00f3metro hasta 60 micr\u00f3metros dependiendo la regi\u00f3n del espectro electromagn\u00e9tico utilizada. Se discuten los principales mecanismos involucrados en la fabricaci\u00f3n y fragmentaci\u00f3n de part\u00edculas met\u00e1licas de oro utilizando pulsos l\u00e1ser ultracortos, algunos de ellos son: modificaci\u00f3n del espectro irradiado debido a efectos no lineales en el medio donde se sumerge la muestra (par\u00e1metro de Keldish). y formaci\u00f3n del espectro supercontinuo debido a efectos no lineales. Como m\u00e9todos para funcionalizaci\u00f3n se presentan resultados empleando fluencia controlada. Se examinan los efectos del supercontinuo en el proceso de fragmentaci\u00f3n aplicando fluencias bajas. El supercontinuo fue generado externamente en un cristal de zafiro y en agua. El cambio m\u00e1s grande fue obtenido para 0.855 J\/cm<SUP>2<\/SUP> de fluencia aplicadas al agua, pues el pico del plasm\u00f3n pas\u00f3 a estar en 521 nm. respecto del pico de la soluci\u00f3n inicial ubicado en 531 nm. Tambi\u00e9n se han dise\u00f1ado procedimientos para la funcionalizaci\u00f3n de part\u00edculas met\u00e1licas n\u00facleo cubierta utilizando distintas fluencias. Se analiza la extinci\u00f3n \u00f3ptica de las suspensiones coloidales de Nps de Ag generadas usando un amplio rango de fluencias (60 J\/cm<SUP>2<\/SUP>, 160 J\/cm<SUP>2<\/SUP>, 800 J\/cm<SUP>2<\/SUP> y 1000 J\/cm<SUP>2<\/SUP>) para caracterizar el tama\u00f1o del n\u00facleo y espesores de la cubierta, observ\u00e1ndose como resultado cambios en la posici\u00f3n del pico de extinci\u00f3n del plasm\u00f3n de acuerdo a los distintos espesores de la cubierta. En estos casos para obtener la extinci\u00f3n se han utilizado expresiones de la aproximaci\u00f3n electrost\u00e1tica para part\u00edculas Por \u00faltimo se han analizado reflectancias de films delgados.Se propone un nuevo m\u00e9todo h\u00edbrido para medida de espesores en multicapas basado en las propiedades \u00f3pticas de la resonanacia de plasmones superficiales y del modo acoplado de guia de onda \u00f3ptica.Por medio de la simulaci\u00f3n de la reflectancia para sistemas multicapa constituidos por plata y \u00f3xido de plata se han obtenido par\u00e1metros caracteristicos que dependen sensiblemente de los espesores y en consecuencia hacen posible la medida.<\/span><\/div><\/summary><div class=\"a_unline\">Compartir: <a href=\"https:\/\/www.facebook.com\/sharer\/sharer.php?p[title]=Desarrollo de t\u00e9cnicas de espectroscop\u00eda de scattering \u00f3ptico y de resonancia plasm\u00f3nica para la determinaci\u00f3n de tama\u00f1o de micro y nanopart\u00edculas&p[url]=http:\/\/sedici.unlp.edu.ar\/handle\/10915\/18185\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-facebook.png\" alt=\"Facebook logo\" title=\"Compartir en Facebook\">\n             <\/a>\n             <a href=\"https:\/\/twitter.com\/?status=Desarrollo de t\u00e9cnicas de espectroscop\u00eda de scattering \u00f3ptico y de resonancia plasm\u00f3nica para la determinaci\u00f3n de tama\u00f1o de micro y nanopart\u00edculas http:\/\/sedici.unlp.edu.ar\/handle\/10915\/18185 via @sedici_unlp\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-twitter.png\" alt=\"Twitter logo\" title=\"Compartir en Twitter\"><\/a>\n             <a href=\"https:\/\/plus.google.com\/share?url=http:\/\/sedici.unlp.edu.ar\/handle\/10915\/18185\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-plus.png\" alt=\"Google+ logo\" title=\"Compartir en Google+\">\n             <\/a>\n             <a href=\"http:\/\/www.linkedin.com\/shareArticle?url=http:\/\/sedici.unlp.edu.ar\/handle\/10915\/18185\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-linkedin.png\" alt=\"Linkedin logo\" title=\"Compartir en Linkedin\">\n             <\/a>\n        <\/div><\/article><\/li><li><article>\n\t\t\t<title>Visible and near-infrared backscattering spectroscopy for sizing spherical microparticles<\/title>\n                        <div id=\"sedici-title\">\n                            <a href=\"http:\/\/sedici.unlp.edu.ar\/handle\/10915\/79195\" target=\"_blank\">Visible and near-infrared backscattering spectroscopy for sizing spherical microparticles<\/a>\n                        <\/div><div id=\"sedici-title\">Autores: <author><name><a href=http:\/\/sedici.unlp.edu.ar\/discover?filtertype=author&filter_relational_operator=equals&filter=Scaffardi%2C%20Luc\u00eda%20Beatriz target=\"_blank\">Scaffardi, Luc\u00eda Beatriz<\/a><\/name><\/author>-<author><name><a href=http:\/\/sedici.unlp.edu.ar\/discover?filtertype=author&filter_relational_operator=equals&filter=Videla%2C%20Fabi\u00e1n%20Alfredo target=\"_blank\">Videla, Fabi\u00e1n Alfredo<\/a><\/name><\/author>-<author><name><a href=http:\/\/sedici.unlp.edu.ar\/discover?filtertype=author&filter_relational_operator=equals&filter=Schinca%2C%20Daniel%20Carlos target=\"_blank\">Schinca, Daniel Carlos<\/a><\/name><\/author><\/div><published>\n                                        <div id=\"sedici-title\">Fecha: <span class=\"sedici-content\">2007-01-01<\/span><\/div>\n                                    <\/published><dc:type>\n                                        <div id=\"sedici-title\">Tipo de documento: <span class=\"sedici-content\">Articulo<\/span><\/div>\n                                    <\/dc:type><summary> <div id=\"sedici-title\">Resumen:<span class=\"sedici-content\">Scattering is a useful tool for the determination of particle size in solution. In particular, spectroscopic analysis of backscattering renders the possibility of a simplified experimental setup and direct data processing using Mie theory. We show that a simple technique based on near-infrared (NIR) backscattering spectroscopy together with the development of the corresponding algorithm based on Fourier transform (FT) and Mie theory are a powerful tool for sizing microparticles in the range from 8 to 60 microm diameter. There are three wavelength intervals in the NIR, within which different diameter ranges were analyzed. In each one, the FT yields a coarse diameter value with an uncertainty dependent on the wavelength range. A more accurate value is obtained by further applying cross correlation between experimental and theoretical spectra. This latter step reduces the uncertainty in diameter determination between 30% and 40%, depending on wavelength interval and particle diameter. These results extend previous information on visible backscattering spectroscopy applied to sizing microparticles in the range between 1 and 24 mum diameter. This technique could be the basis for the construction of a portable and practical instrument.<\/span><\/div><\/summary><div class=\"a_unline\">Compartir: <a href=\"https:\/\/www.facebook.com\/sharer\/sharer.php?p[title]=Visible and near-infrared backscattering spectroscopy for sizing spherical microparticles&p[url]=http:\/\/sedici.unlp.edu.ar\/handle\/10915\/79195\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-facebook.png\" alt=\"Facebook logo\" title=\"Compartir en Facebook\">\n             <\/a>\n             <a href=\"https:\/\/twitter.com\/?status=Visible and near-infrared backscattering spectroscopy for sizing spherical microparticles http:\/\/sedici.unlp.edu.ar\/handle\/10915\/79195 via @sedici_unlp\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-twitter.png\" alt=\"Twitter logo\" title=\"Compartir en Twitter\"><\/a>\n             <a href=\"https:\/\/plus.google.com\/share?url=http:\/\/sedici.unlp.edu.ar\/handle\/10915\/79195\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-plus.png\" alt=\"Google+ logo\" title=\"Compartir en Google+\">\n             <\/a>\n             <a href=\"http:\/\/www.linkedin.com\/shareArticle?url=http:\/\/sedici.unlp.edu.ar\/handle\/10915\/79195\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-linkedin.png\" alt=\"Linkedin logo\" title=\"Compartir en Linkedin\">\n             <\/a>\n        <\/div><\/article><\/li><li><article>\n\t\t\t<title>Alternative method for concentration retrieval in differential optical absorption spectroscopy atmospheric gas pollutant measurements<\/title>\n                        <div id=\"sedici-title\">\n                            <a href=\"http:\/\/sedici.unlp.edu.ar\/handle\/10915\/44353\" target=\"_blank\">Alternative method for concentration retrieval in differential optical absorption spectroscopy atmospheric gas pollutant measurements<\/a>\n                        <\/div><div id=\"sedici-title\">Autores: <author><name><a href=http:\/\/sedici.unlp.edu.ar\/discover?filtertype=author&filter_relational_operator=equals&filter=Videla%2C%20Fabi\u00e1n%20Alfredo target=\"_blank\">Videla, Fabi\u00e1n Alfredo<\/a><\/name><\/author>-<author><name><a href=http:\/\/sedici.unlp.edu.ar\/discover?filtertype=author&filter_relational_operator=equals&filter=Schinca%2C%20Daniel%20Carlos target=\"_blank\">Schinca, Daniel Carlos<\/a><\/name><\/author>-<author><name><a href=http:\/\/sedici.unlp.edu.ar\/discover?filtertype=author&filter_relational_operator=equals&filter=Tocho%2C%20Jorge%20Omar target=\"_blank\">Tocho, Jorge Omar<\/a><\/name><\/author><\/div><published>\n                                        <div id=\"sedici-title\">Fecha: <span class=\"sedici-content\">2003-06-01<\/span><\/div>\n                                    <\/published><dc:type>\n                                        <div id=\"sedici-title\">Tipo de documento: <span class=\"sedici-content\">Articulo<\/span><\/div>\n                                    <\/dc:type><summary> <div id=\"sedici-title\">Resumen:<span class=\"sedici-content\">Differential optical absorption spectroscopy is a widely used technique for open-column atmospheric-gas pollution monitoring. The concentration retrieval is based on the fitting of the measured differential absorbance through the Lambert-Beer law. We present an alternative method for calculating the gas concentration on the basis of the proportionality between differential absorbance and differential absorption cross section of the gas under study. The method can be used on its own for single-component analysis or as a complement to the standard technique in multicomponent cases. The performance of the method for the case of cross interference between two gases is analyzed. The procedure can be used with differential absorption cross sections measured in the laboratory or taken from the literature. In addition, the method provides a criterion to discriminate against different species having absorption features in the same wavelength range.<\/span><\/div><\/summary><div class=\"a_unline\">Compartir: <a href=\"https:\/\/www.facebook.com\/sharer\/sharer.php?p[title]=Alternative method for concentration retrieval in differential optical absorption spectroscopy atmospheric gas pollutant measurements&p[url]=http:\/\/sedici.unlp.edu.ar\/handle\/10915\/44353\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-facebook.png\" alt=\"Facebook logo\" title=\"Compartir en Facebook\">\n             <\/a>\n             <a href=\"https:\/\/twitter.com\/?status=Alternative method for concentration retrieval in differential optical absorption spectroscopy atmospheric gas pollutant measurements http:\/\/sedici.unlp.edu.ar\/handle\/10915\/44353 via @sedici_unlp\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-twitter.png\" alt=\"Twitter logo\" title=\"Compartir en Twitter\"><\/a>\n             <a href=\"https:\/\/plus.google.com\/share?url=http:\/\/sedici.unlp.edu.ar\/handle\/10915\/44353\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-plus.png\" alt=\"Google+ logo\" title=\"Compartir en Google+\">\n             <\/a>\n             <a href=\"http:\/\/www.linkedin.com\/shareArticle?url=http:\/\/sedici.unlp.edu.ar\/handle\/10915\/44353\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/imapec.ing.unlp.edu.ar\/wp-content\/plugins\/wp-dspace\/media\/img\/share-linkedin.png\" alt=\"Linkedin logo\" title=\"Compartir en Linkedin\">\n             <\/a>\n        <\/div><\/article><\/li><\/ul>\n            <div class=\"page_navigation \" ><\/div>\n            <\/div>\n","protected":false},"excerpt":{"rendered":"<p>Publicaciones en SEDICI<\/p>\n","protected":false},"author":6,"featured_media":0,"parent":82,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/imapec.ing.unlp.edu.ar\/wp-json\/wp\/v2\/pages\/349"}],"collection":[{"href":"https:\/\/imapec.ing.unlp.edu.ar\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/imapec.ing.unlp.edu.ar\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/imapec.ing.unlp.edu.ar\/wp-json\/wp\/v2\/users\/6"}],"replies":[{"embeddable":true,"href":"https:\/\/imapec.ing.unlp.edu.ar\/wp-json\/wp\/v2\/comments?post=349"}],"version-history":[{"count":1,"href":"https:\/\/imapec.ing.unlp.edu.ar\/wp-json\/wp\/v2\/pages\/349\/revisions"}],"predecessor-version":[{"id":350,"href":"https:\/\/imapec.ing.unlp.edu.ar\/wp-json\/wp\/v2\/pages\/349\/revisions\/350"}],"up":[{"embeddable":true,"href":"https:\/\/imapec.ing.unlp.edu.ar\/wp-json\/wp\/v2\/pages\/82"}],"wp:attachment":[{"href":"https:\/\/imapec.ing.unlp.edu.ar\/wp-json\/wp\/v2\/media?parent=349"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
