Customer Relationship Management-PeopleSoft CRM

1 RESUMEN 1.1 Resumen (español) El intercambio y comercio tanto de bienes como servicios se remonta a tiempos inmemoriales dentro de la historia de la humanidad. Desde sus inicios tempranos con el intercambio o trueque de productos en el Neolítico hasta nuestra época híper globalizada, en la que existen clientes potenciales en el otro extremo del mundo, podemos decir que se ha recorrido un largo camino. Con el paso del tiempo y la evolución de la sociedad y la tecnología, así como la evolución empresarial, se ha visto necesario la implementación de estrategias para lograr la fidelización y satisfacción de los clientes. De esta forma entendimos que ya no valía simplemente con vender un producto a un cliente, si no que si queríamos establecer una relación continúa con el mismo, debíamos lograr su satisfacción y por tanto su fidelización. Como forma de extender la relación más allá de una simple venta, las empresas modernas empezaron a implementar diversas estrategias. De esta forma aparecieron los primeros centros de atención al cliente, las primeras aplicaciones hechas a medida para dar soporte a los clientes y por fin los sistemas CRM tal y como los concebimos hoy día. El presente proyecto fin de carrera da una explicación de dichos sistemas indicando cuáles son sus objetos fundamentales y cómo implementan la estrategia CRM y profundiza en uno de los sistemas CRM más utilizados: PeopleSoft CRM, dando una explicación detallada de dicho sistemas así como de los conceptos y lenguaje de programación de dicho sistema CRM. 1.2 SUMMARY (ENGLISH) The exchange and trade of goods as well and services goes back to ancient times in the history of mankind. Since its early beginning with the bartering of products in the Neolithic to our globalized hyper era, in which there are potential customers on the other side of the world, we can say that it has come a long way. After a certain length of time, the society and technology evolution, and also the enterprise development, has been necessary to implement strategies to achieve customer loyalty and satisfaction. We understood in this way that it no longer simply worth to sell a product to a customer, otherwise if we wanted to establish a relationship continues with the same, we should ensure their satisfaction and thus their loyalty. As a way to extend the relationship beyond a simple sale, modern enterprises began to implement several strategies. Therefore appeared the first customer service centers, the first applications tailored to support customers and finally the CRM systems as we know it today. This final project gives an explanation of such systems by indicating what the core objects are and how to implement the CRM strategy, deeping into one of the most widely used CRM systems: PeopleSoft CRM, and also giving a detailed explanation of this system and its programming language.

A methodology to compute emission projections from road transport (EmiTRANS)

Atmospheric emissions from road transport have increased all around the world during the last decades more rapidly than from other pollution sources. For instance, they contribute to more than 25% of total CO, CO2, NOx, and fine particle emissions in most of the European countries. This situation shows the importance of road transport when complying with emission ceilings and air quality standards applied to these pollutants. This paper presents a modelling system to perform atmospheric emission projections (simultaneously both air quality pollutants and greenhouse gases) from road transport including the development of a tailored software tool (EmiTRANS) as a planning tool. The methodology has been developed with two purposes: 1) to obtain outputs used as inputs to the COPERT4 software to calculate emission projections and 2) to summarize outputs for policy making evaluating the effect of emission abatement measures for a vehicle fleet. This methodology has been applied to the calculation of emission projections in Spain up to 2020 under several scenarios, including a sensitivity analysis useful for a better interpretation and confidence building on the results. This case study demonstrates the EmiTRANS applicability to a country, and points out the need for combining both technical and non-technical measures (such as behavioural changes or demand management) to reduce emissions, indirectly improving air quality and contributing to mitigate climate change.

Metodología de Diseño y Análisis de Sistemas Teleoperados Considerando Dinámica No Lineal

Cuando la separación física entre el sistema local y remoto es relativamente corta, el retardo no es perceptible; sin embargo, cuando el manipulador local y el manipulador remoto se encuentran a una distancia lejana uno del otro, el retardo de tiempo ya no es insignificante e influye negativamente en la realización de la tarea. El retardo de tiempo en un sistema de control introduce un atraso de fase que a su vez degrada el rendimiento del sistema y puede causar inestabilidad. Los sistemas de teleoperación pueden sacar provecho de la posibilidad de estar presente en dos lugares simultáneamente, sin embargo, el uso de Internet y otras redes de conmutación de paquetes, tales como Internet2, impone retardos de tiempo variables, haciendo que los esquemas de control ya establecidos elaboren soluciones para hacer frente a inestabilidades causadas por estos retardos de tiempo variables. En este trabajo de tesis se presenta el modelado y análisis de un sistema de teloperación bilateral no lineal de n grados de libertad controlado por convergencia de estado. La comunicación entre el sitio local y remoto se realiza mediante un canal de comunicación con retardo de tiempo. El análisis presentado en este trabajo considera que el retardo puede ser constante o variable. Los principales objetivos de este trabajo son; 1) Desarrollar una arquitectura de control no lineal garantizando la estabilidad del sistema teleoperado, 2) Evaluar la estabilidad del sistema considerando el retardo en la comunicación, y 3) Implementación de los algoritmos desarrollados para probar el desempeño de los mismos en un sistema experimental de 3 grados de libertad. A través de la teoría de Estabilidad de Lyapunov y el funcional Lyapunov-Krasovskii, se demuestra que el sistema de lazo cerrado es asintóticamente estable. Estas conclusiones de estabilidad se han obtenido mediante la integración de la función de Lyapunov y aplicando el Lema de Barbalat. Se demuestra también que se logra sincronizar las posiciones del manipulador local y remoto cuando el operador humano no mueve el manipulador local y el manipulador remoto se mueve libremente. El esquema de control propuesto se ha validado mediante simulación y en forma experimental empleando un sistema de teleoperación real desarrollado en esta tesis doctoral y que consta de un un manipulador serie planar de tres grados de libertad, un manipulador local, PHANTOM Omni, el cual es un dispositivo haptico fabricado que consta de 3 grados de libertad (en fuerza) y que proporciona realimentación de fuerza en los ejes x,y,z. El control en tiempo real se ha diseñado usando el Sistema Operativo en Tiempo Real QuaRC de QUARC en el lado local y el Simulink Real-Time Windows TargetTM en el lado remoto. Para finalizar el resumen se destaca el impacto de esta tesis en el mundo científico a través de los resultados publicados: 2 artículos en revistas con índice de impacto , 1 artículo en una revista indexada en Sistemas, Cibernética e Informática, 7 artículos en congresos y ha obtenido un premio en la 9a. Conferencia Iberoamericana en Sistemas, Cibernética e Informática, 2010. ABSTRACT When the physical separation between the local and remote system is relatively short, the delay is not noticeable; however, when the local manipulator and the remote manipulator are at a far distance from each other, the time delay is no longer negligible and negatively influences the performance of the task. The time delay in a control system introduces a phase delay which in turn degrades the system performance and cause instability. Teleoperation systems can benefit from the ability to be in two places simultaneously, however, the use of Internet and other packet switched networks, such as Internet2, imposes varying time delays, making established control schemes to develop solutions to address these instabilities caused by different time delays. In this thesis work we present a modeling and analysis of a nonlinear bilateral teloperation system of n degrees of freedom controlled by state convergence strategy. Communication between the local and remote site is via a communication channel with time delay. The analysis presented in this work considers that the time-delay can be constant or variable. The main objectives of this work are; 1) Develop a nonlinear control schemes to ensure the stability of the teleoperated system, 2) Evaluate the system stability considering the delay in communication, and 3) Implementation of algorithms developed to test the performance of the teleoperation system in an experimental system of 3 degrees of freedom. Through the Theory of Stability of Lyapunov and the functional Lyapunov-Krasovskii, one demonstrates that the closed loop system is asymptotically stable.. The conclusions about stability were obtained by integration of the Lyapunov function and applying Barbalat Lemma. It further shows that the positions of the local and remote manipulator are synchronize when the human operator stops applying a constant force and the remote manipulator does not interact with the environment. The proposed control scheme has been validated by means of simulation and in experimental form using a developed system of real teleoperation in this doctoral thesis, which consists of a series planar manipulator of three degrees of freedom, a local manipulator, PHANTOM Omni, which is an haptic device that consists of 3 degrees of freedom (in force) and that provide feeback force in x-axis, and, z. The control in real time has been designed using the Operating system in Real time QuaRC of Quanser in the local side and the Simulink Real-Time Windows Target in the remote side. In order to finalize the summary, the highlights impact of this thesis in the scientific world are shows through the published results: 2 articles in Journals with impact factor, one article in a indexed Journal on Systemics, Cybernetics and Informatics, 7 articles in Conferences and has won an award in 9a.

Estudio teórico-experimental sobre el deterioro en tableros de puentes de hormigón producido por la acción del hielo-deshielo con sales de fundentes

El deterioro del hormigón por ciclos de hielo-deshielo en presencia de sales fundentes es causa frecuente de problemas en los puentes e infraestructuras existentes en los países europeos. Los daños producidos por los ciclos de hielo-deshielo en el hormigón pueden ser internos, fundamentalmente la fisuración y/o externos como el descascarillamiento (desgaste superficial). La España peninsular presenta unas características geográficas y climáticas particulares. El 18% de la superficie tiene una altura superior a 1000mts y, además, la altura media geográfica con respecto al nivel del mar es de 660mts (siendo el segundo país más montañoso de toda Europa).Esto hace que la Red de Carreteras del Estado se vea afectada, durante determinados periodos, por fenómenos meteorológicos adversos, en particular por nevadas y heladas, que pueden comprometer las condiciones de vialidad para la circulación de vehículos. Por este motivo la Dirección General de Carreteras realiza trabajos anualmente (campañas de vialidad invernal, de 6 meses de duración) para el mantenimiento de la vialidad de las carreteras cuando éstas se ven afectadas por estos fenómenos. Existen protocolos y planes operativos que permiten sistematizar estos trabajos de mantenimiento que, además, se han intensificado en los últimos 10 años, y que se fundamentan en el empleo de sales fundentes, principalmente NaCl, con la misión de que no haya placas de hielo, ni nieve, en las carreteras. En zonas de fuerte oscilación térmica, que con frecuencia en España se localizan en la zona central del Pirineo, parte de la cornisa Cantábrica y Sistema Central, se producen importantes deterioros en las estructuras y paramentos de hormigón producidos por los ciclos de hielo- deshielo. Pero además el uso de fundentes de vialidad invernal acelera en gran medida la evolución de estos daños. Los tableros de hormigón de puentes de carretera de unos 40-50 años de antigüedad carecen, en general, de un sistema de impermeabilización, y están formados frecuentemente por un firme de mezcla asfáltica, una emulsión adherente y el hormigón de la losa. En la presente tesis se realiza una investigación que pretende reproducir en laboratorio los procesos que tienen lugar en el hormigón de tableros de puentes existentes de carreteras, de unos 40-50 años de antigüedad, que están expuestos durante largos periodos a sales fundentes, con objeto de facilitar la vialidad invernal, y a cambios drásticos de temperatura (hielo y deshielo). Por ello se realizaron cuatro campañas de investigación, teniendo en cuenta que, si bien nos basamos en la norma europea UNE-CEN/TS 12390-9 “Ensayos de hormigón endurecido. Resistencia al hielo-deshielo. Pérdida de masa”, se fabricaron probetas no estandarizadas para este ensayo, pensado en realidad para determinar la afección de los ciclos únicamente a la pérdida de masa. Las dimensiones de las probetas en nuestro caso fueron 150x300 mm, 75 x 150mm (cilíndricas normalizadas para roturas a compresión según la norma UNE-EN 12390-3) y 286x76x76 (prismáticas normalizadas para estudiar cambio de volumen según la norma ASTM C157), lo cual nos permitió realizar sobre las mismas probetas más ensayos, según se presentan en la tesis y, sobre todo, poder comparar los resultados con probetas extraídas de dimensiones similares en puentes existentes. En la primera campaña, por aplicación de la citada norma, se realizaron ciclos de H/D, con y sin contacto con sales de deshielo (NaCl en disolución del 3% según establece dicha norma). El hormigón fabricado en laboratorio, tratando de simular el de losas de tableros de puentes antiguos, presentó una fc de 22,6 MPa y relación agua/cemento de 0,65. Las probetas de hormigón fabricadas se sometieron a ciclos agresivos de hielo/deshielo (H/D), empleando una temperatura máxima de +20ºC y una temperatura mínima de -20ºC al objeto de poder determinar la sensibilidad de este ensayo tanto al tipo de hormigón elaborado como al tipo de probeta fabricado (cilíndrica y prismática). Esta campaña tuvo una segunda fase para profundizar más en el comportamiento de las probetas sometidas a ciclos H/D en presencia de sales. En la segunda campaña, realizada sobre probetas de hormigón fabricadas en laboratorio iguales a las anteriores, la temperaturas mínima del ensayo se subió a -14ºC, lo que nos permitió analizar el proceso de deterioro con más detalle. (Realizando una serie de ensayos de caracterización no destructivos y otros destructivos, y validando su aplicación a la detección de los deterioros causados tras los ensayos acelerados de hielodeshielo. También mediante aplicación de técnicas de microscopía electrónica.) La tercera campaña, se realizó sobre probetas de hormigón de laboratorio similares a las anteriores, fc de 29,3Mpa y relación a/c de 0,65, en las que se aplicó en una cara un revestimiento asfáltico de 2-4cms, según fueran prismáticas y cilíndricas respectivamente, compuesto por una mezcla asfáltica real (AC16), sobre una imprimación bituminosa. (Para simular el nivel de impermeabilización que produce un firme sobre el tablero de un puente) La cuarta campaña, se desarrolló tras una cuidadosa selección de dos puentes de hormigón de 40-50 años de antigüedad, expuestos y sensibles a deterioros de hielodeshielo, y en carreteras con aportación de fundentes. Una vez esto se extrajeron testigos de hormigón de zonas sanas (nervios del tablero), para realizar en laboratorio los mismos ensayos acelerados de hielo-deshielo y de caracterización, de la segunda campaña, basados en la misma norma. De los resultados obtenidos se concluye que cuando se emplean sales fundentes se acelera de forma significativa el deterioro, aumentando tanto el contenido de agua en los poros como el gradiente generado (mecanismo de deterioro físico). Las sales de deshielo aceleran claramente la aparición del daño, que se incrementa incluso en un factor de 5 según se constata en esta investigación para los hormigones ensayados. Pero además se produce un gradiente de cloruros que se ha detectado tanto en los hormigones diseñados en laboratorio como en los extraídos de puentes existentes. En casi todos los casos han aparecido cambios en la microestructura de la pasta de cemento (mecanismo de deterioro químico), confirmándose la formación de un compuesto en el gel CSH de la pasta de cemento, del tipo Ca2SiO3Cl2, que posiblemente está contribuyendo a la alteración de la pasta y a la aceleración de los daños en presencia de sales fundentes. Existe un periodo entre la aparición de fisuración y la pérdida de masa. Las fisuras progresan rápidamente desde la interfase de los áridos más pequeños y angulosos, facilitando así el deterioro del hormigón. Se puede deducir así que el tipo de árido afecta al deterioro. En el caso de los testigos con recubrimiento asfáltico, parece haberse demostrado que la precipitación de sales genera tensiones en las zonas de hormigón cercanas al recubrimiento, que terminan por fisurar el material. Y se constata que el mecanimo de deterioro químico, probablemente tenga más repercusión que el físico, por cuanto el recubrimiento asfáltico es capaz de retener suficiente agua, como para que el gradiente de contenido de agua en el hormigón sea mucho menor que sin el recubrimiento. Se constató, sin embargo, la importancia del gradiente de cloruros en el hormigon. Por lo que se deduce que si bien el recubrimiento asfáltico es ciertamente protector frente a los ciclos H/D, su protección disminuye en presencia de sales; es decir, los cloruros acabarán afectando al hormigón del tablero del puente. Finalmente, entre los hormigones recientes y los antiguos extraídos de puentes reales, se observa que existen diferencias significativas en cuanto a la resistencia a los ciclos H/D entre ellos. Los hormigones más recientes resultan, a igualdad de propiedades, más resistentes tanto a ciclos de H/D en agua como en sales. Posiblemente el hecho de que los hormigones de los puentes hayan estado expuestos a condiciones de temperaturas extremas durante largos periodos de tiempo les ha sensibilizado. La tesis realizada, junto con nuevos contrastes que se realicen en el futuro, nos permitirá implementar una metodología basada en la extracción de testigos de tableros de puente reales para someterlos a ensayos de hielo-deshielo, basados en la norma europea UNECEN/ TS 12390-9 aunque con probetas no normalizadas para el mismo, y, a su vez, realizar sobre estas probetas otros ensayos de caracterización destructivos, que posibilitarán evaluar los daños ocasionados por este fenómeno y su evolución temporal, para actuar consecuentemente priorizando intervenciones de impermeabilización y reparación en el parque de puentes de la RCE. Incluso será posible la elaboración de mapas de riesgo, en función de las zonas de climatología más desfavorable y de los tratamientos de vialidad invernal que se lleven a cabo. Concrete damage by freeze-thaw cycles in the presence of melting salts frequently causes problems on bridges and infrastructures in European countries. Damage caused by freeze-thaw cycles in the concrete can be internal, essentially cracking and / or external as flaking (surface weathering due to environmental action). The peninsular Spain presents specific climatic and geographical characteristics. 18% of the surface has a height greater than 1,000 m and the geographical average height from the sea level is 660 m (being the second most mountainous country in Europe). This makes the National Road Network affected during certain periods due to adverse weather, particularly snow and ice, which can compromise road conditions for vehicular traffic. For this reason the National Road Authority performs works annually (Winter Road Campaign, along 6 months) to maintain the viability of the roads when they are affected by these phenomena. There are protocols and operational plans that allow systematize these maintenance jobs, that also have intensified in the last 10 years, and which are based on the use of deicing salts, mainly NaCl, with the mission that no ice sheets, or snow appear on the roads. In areas of strong thermal cycling, which in Spain are located in the central area of the Pyrenees, part of the Cantabrian coast and Central System, significant deterioration take place in the structures and wall surfaces of concrete due to freeze-thaw. But also the use of deicing salts for winter maintenance greatly accelerated the development of such damages. The concrete decks for road bridges about 40-50 years old, lack generally a waterproofing system, and are often formed by a pavement of asphalt, an adhesive emulsion and concrete slab. In this thesis the research going on aims to reproduce in the laboratory the processes taking place in the concrete of an existing deck at road bridges, about 40-50 years old, they are exposed for long periods to icing salt, to be performed in order to facilitate winter maintenance, and drastic temperature changes (freezing and thawing). Therefore four campaigns of research were conducted, considering that while we rely on the European standard UNE-CEN/TS 12390-9 "Testing hardened concrete. Freezethaw resistance. Mass loss", nonstandard specimens were fabricated for this test, actually conceived to determine the affection of the cycles only to the mass loss. Dimensions of the samples were in our case 150x300 mm, 75 x 150mm (standard cylindrical specimens for compression fractures UNE-EN 12390-3) and 286x76x76 (standard prismatic specimens to study volume change ASTM C157), which allowed us to carry on same samples more trials, as presented in the thesis, and especially to compare the results with similar sized samples taken from real bridges. In the first campaign, by application of that European standard, freeze-thaw cycles, with and without contact with deicing salt (NaCl 3% solution in compliance with such standard) were performed. Concrete made in the laboratory, trying to simulate the old bridges, provided a compressive strength of 22.6 MPa and water/cement ratio of 0.65. In this activity, the concrete specimens produced were subjected to aggressive freeze/thaw using a maximum temperature of +20ºC and a minimum temperature of - 20°C in order to be able to determine the sensitivity of this test to the concrete and specimens fabricated. This campaign had a second phase to go deeper into the behavior of the specimens subjected to cycled freeze/thaw in the presence of salts. In the second campaign, conducted on similar concrete specimens manufactured in laboratory, temperatures of +20ºC and -14ºC were used in the tests, which allowed us to analyze the deterioration process in more detail (performing a series of non-destructive testing and other destructive characterization, validating its application to the detection of the damage caused after the accelerated freeze-thaw tests, and also by applying electron microscopy techniques). The third campaign was conducted on concrete specimens similar to the above manufactured in laboratory, both cylindrical and prismatic, which was applied on one side a 4 cm asphalt coating, consisting of a real asphalt mixture, on a bituminous primer (for simulate the level of waterproofing that produces a pavement on the bridge deck). The fourth campaign was developed after careful selection of two concrete bridges 40- 50 years old, exposed and sensitive to freeze-thaw damage, in roads with input of melting salts. Concrete cores were extracted from healthy areas, for the same accelerated laboratory freeze-thaw testing and characterization made for the second campaign, based on the same standard. From the results obtained it is concluded that when melting salts are employed deterioration accelerates significantly, thus increasing the water content in the pores, as the gradient. Besides, chloride gradient was detected both in the concrete designed in the laboratory and in the extracted in existing bridges. In all cases there have been changes in the microstructure of the cement paste, confirming the formation of a compound gel CSH of the cement paste, Ca2SiO3Cl2 type, which is possibly contributing to impair the cement paste and accelerating the damage in the presence of melting salts. The detailed study has demonstrated that the formation of new compounds can cause porosity at certain times of the cycles may decrease, paradoxically, as the new compound fills the pores, although this phenomenon does not stop the deterioration mechanism and impairments increase with the number of cycles. There is a period between the occurrence of cracking and mass loss. Cracks progress rapidly from the interface of the smallest and angular aggregate, thus facilitating the deterioration of concrete. It can be deduced so the aggregate type affects the deterioration. The presence of melting salts in the system clearly accelerates the onset of damage, which increases even by a factor of 5 as can be seen in this investigation for concrete tested. In the case of specimens with asphalt coating, it seems to have demonstrated that the precipitation of salts generate tensions in the areas close to the concrete coating that end up cracking the material. It follows that while the asphalt coating is certainly a protection against the freeze/thaw cycles, this protection decreases in the presence of salts; so the chlorides will finally affect the concrete bridge deck. Finally, among the recent concrete specimens and the old ones extracted from real bridges, it is observed that the mechanical strengths are very similar to each other, as well as the porosity values and the accumulation capacity after pore water saturation. However, there are significant differences in resistance to freeze/thaw cycles between them. More recent concrete are at equal properties more resistant both cycles freeze/thaw in water with or without salts. Possibly the fact that concrete bridges have been exposed to extreme temperatures for long periods of time has sensitized them. The study, along with new contrasts that occur in the future, allow us to implement a methodology based on the extraction of cores from the deck of real bridges for submission to freeze-thaw tests based on the European standard UNE-CEN/TS 12390-9 even with non-standard specimens for it, and in turn, performed on these samples other destructive characterization tests, which will enable to assess the damage caused by this phenomenon and its evolution, to act rightly prioritizing interventions improving the waterproofing and other repairs in the bridge stock of the National Road Network. It will even be possible to develop risk maps, depending on the worst weather areas and winter road treatments to be carried out.

Aplicación de la energía solar térmica en una incubadora comercial de perdiz roja y supervisión de la actividad biológica mediante sensores inteligentes

La perdiz roja es la especie cinegética por excelencia en la península ibérica, cuya cría en cautividad y suelta controlada comenzó a regularse en los años 70 con la aparición del ICONA. La incubación controlada de huevos de perdiz es imprescindible, con fines cinegéticos y de preservación de la especie, y se desarrolla con incubadoras comerciales de pequeña y mediana escala, distribuidas en zonas rurales con acceso limitado y/o deficiente al suministro eléctrico. En nuestras latitudes el aporte de energía solar térmica se perfila como una posibilidad de mejorar la eficiencia energética de éstas y otras instalaciones y de reducir la dependencia energética exterior. Hay diversos factores físico-químicos que influyen en la calidad de la incubación: temperatura, humedad relativa, y concentración de gases, de los cuales sólo los dos primeros son habitualmente supervisados y controlados en este tipo de incubadoras. Esta Tesis surge en el marco de dos proyectos de cooperación con la AECID, y tiene como objetivos: la caracterización espacial de variables relevantes (temperatura (T), humedad relativa (HR)) en la incubadora comercial durante el proceso de incubación, la determinación de la relación existente entre la evolución de variables ambientales durante el proceso de incubación y la tasa de nacimientos (35-77%), así como el diseño y evaluación del sistema de apoyo solar térmico para determinar su potencial de utilización durante las incubaciones comerciales. La instalación de un número limitado de sensores permite la monitorización precisa del proceso de incubación de los huevos. Los resultados más relevantes indican que en incubaciones comerciales los gradientes de T y HR han sido despreciables (1ºC de diferencia entre las posiciones con mayor y menor T media y un 4,5% de diferencia entre las posiciones con mayor y menor HR), mientras que el seguimiento y ajuste (mediante modelos de crecimiento) de la concentración de CO2 (r2 entre 0,948 y 0,987 en las 5 incubaciones, para un total de 43315 huevos) permite valorar la actividad fisiológica de los huevos e incluso predecir la tasa de éxito (nacimientos), basándose en la concentración de CO2 estimada mediante modelos de crecimiento en el día 20 de incubación (r2 entre 0,997 y 0,994 según el modelo de estimación empleado). El sistema ha sido valorado muy positivamente por los productores (Finca Cinegética Dehesa Vieja de Galapagar). El aporte térmico se ha diseñado (con mínima intrusión en el sistema comercial) sobre la base de un sistema de enfriamiento de emergencia original de la incubadora, al que se han incorporado un colector solar, un depósito, un sistema de electroválvulas, una bomba de circulación y sensores de T en distintos puntos del sistema, y cuyo control ha sido automatizado. En esta Tesis se muestra que la contribución solar puede aportar hasta un 42% de las demandas de energía en nuestras condiciones geográficas para una temperatura de consigna dentro de la incubadora de 36.8ºC, sin afectar a la estabilidad de la temperatura. Además, el rendimiento del colector solar se ha acotado entre un 44% y un 85%, de acuerdo con los cálculos termodinámicos; valores que se mantienen dentro del rango aportado por el fabricante (61%). En el futuro se plantea evaluar el efecto de distintas estrategias de control, tales como controladores difusos, que incorporan el conocimiento experto al control automático. ABSTRACT The partridge is the quintessential game species in the Iberian Peninsula, which controlled breeding and release, began to be regulated in the 70s with the emergence of ICONA. The controlled incubation of eggs is essential, and takes place in commercial incubators of small and medium scale, distributed in rural areas with limited and/or inadequate access to power. In our latitudes the contribution of solar thermal energy is emerging as a possibility to improve the energy efficiency of the facilities and to reduce external energy dependence. There are various physicochemical factors influencing the quality of incubation: temperature, relative humidity and concentration of gases, of which only the first two are typically monitored and controlled in such incubators. This PhD comes within the framework of two cooperation projects with AECID and aims: the spatial characterization of relevant variables in a commercial incubator (temperature (T), and relative humidity (HR)), determining the relationships in the changes in environmental variables during incubation and birth rates (35-77%) as well as the design and evaluation of solar thermal support system to determine its potential use during commercial incubations; the installation of a limited number of sensors has allowed accurate monitoring of incubation of eggs. The most relevant results indicate that in commercial incubations, the gradients in T and HR have been negligible (1°C difference between the highest and lowest positions T and average 4.5% difference between the highest and lowest positions HR), while monitoring and fit using growth models of the concentration of CO2 (r2 between 0.948 and 0.987 in 5 incubations, for a total amount of 43,315 eggs) allows assessing the physiological activity of the eggs and even predict the success rate (hatchability), based on the estimated concentration of CO2 by using growth models on day 20 of incubation (r2 between 0.997 and 0.994 depending on the fit model).The system has been highly valued by producers (Finca Cinegética Dehesa Vieja de Galapagar). The hybrid heat system is designed (with minimal intrusion into the commercial system) based on an emergency cooling device, original in the incubator. New elements have been incorporated: a solar collector, a tank, a system of solenoid valves, a circulating pump and T sensors at various points of the system, whose control has been automated. This PhD shows that the solar contribution is responsible for up to 42% of energy demands in our geographical conditions for a setpoint temperature inside the incubator of 36.8ºC, without questioning the stability of the temperature. Furthermore, the efficiency of the solar collector has been bounded between 44% and 85%, according to thermodynamic calculations; values remain within the range provided by the manufacturer (61%). In the future it is proposed to evaluate the effect of different control strategies, such as fuzzy controllers, which incorporate the expertise to automated control.

1950 En torno al Museo Louisiana 1970

La tesis “1950 En torno al Museo Louisiana 1970” analiza varias obras relacionadas con el espacio doméstico, que se realizaron entre 1950 y 1970 en Dinamarca, un periodo de esplendor de la Arquitectura Moderna. Tras el aislamiento y restricciones del conflicto bélico que asoló Europa, los jóvenes arquitectos daneses, estaban deseosos por experimentar nuevas ideas de procedencia internacional, favorecidos por diferentes circunstancias, encuentran el mejor campo de ensayo en el espacio doméstico. La mejor arquitectura doméstica en Dinamarca, de aquel periodo, debe entenderse como un sistema compuesto por diferentes autores, que tienen en común muchas más similitudes que diferencias, se complementan unos a otros. Para la comprensión y el entendimiento de ello se hace necesario el estudio de varias figuras y edificios, que completen este sistema cuya investigación está escasamente desarrollada. La tesis propone un viaje para conocer los nombres de algunos de sus protagonistas, que mostraron con su trabajo, que tradición y vanguardia no estarán reñidas. El objetivo es desvelar las claves de la Modernidad Danesa, reconocer, descubrir y recuperar el legado de algunos de sus protagonistas en el ámbito doméstico, cuya lección se considera de total actualidad. Una arquitectura que asume las aportaciones extranjeras con moderación y crítica, cuya íntima relación con la tradición arquitectónica y la artesanía propias, será una de sus notas especiales. Del estudio contrastado de varios proyectos y versiones, se obtienen valores comunes entre sus autores, al igual que se descubren sus afinidades o diferencias respecto a los mismos asuntos; que permitirán comprender sus actuaciones según las referencias e influencias, y definir las variables que configuran sus espacios arquitectónicos. La línea de conexión entre los edificios elegidos será su particular relación con la naturaleza y el lugar en que se integran. La fachada, lugar donde se negociará la relación entre el interior y el paisaje, será un elemento entendido de un modo diferente en cada uno de ellos, una relación que se extenderá en todas ellas, más allá de su perímetro. La investigación se ha estructurado en seis capítulos, que van precedidos de una Introducción. En el capítulo primero, se estudian y se señalan los antecedentes, las figuras y edificios más relevantes de la Tradición Danesa, para la comprensión y el esclarecimiento de algunas de las claves de su Modernidad en el campo de la Arquitectura, que se produce con una clara intención de encontrar su propia identidad y expresión. Esta Modernidad floreciente se caracteriza por la asimilación de otras culturas extranjeras desde la moderación, con un punto de vista crítico, y encuentra sus raíces ancladas a la tradición arquitectónica y la artesanía propia, que fragua en la aparición de un ideal común con enorme personalidad y que hoy se valora como una auténtica aportación de una cultura considerada entonces periférica. Se mostrará el debate y el camino seguido por las generaciones anteriores, a las obras análizadas. Las sensibilidades por lo vernáculo y lo clásico, que aparentemente son contradictorias, dominaran el debate con la misma veracidad y respetabilidad. La llamada tercera generación por Sigfried Giedion reanudará la práctica entre lo clásico y lo vernáculo, apoyados en el espíritu del trabajo artesanal y de la tradición, con el objetivo de conocer del acto arquitectónico su “la verdad” y “la esencia original”. El capítulo segundo, analiza la casa Varming, de 1953, situada en un área residencial de Gentofte, por Eva y Nils Koppel, que reinterpreta la visión de Asplund de un paisaje interior continuación del exterior, donde rompen la caja de ladrillo macizo convencional propia de los años 30. Es el ejemplo más poderoso de la unión de tradición e innovación en su obra residencial. Sus formas sobrias entre el Funcionalismo Danés y la Modernidad se singularizarán por su abstracción y volúmenes limpios que acentúan el efecto de su geometría, prismática y brutalista. El desplazamiento de los cuerpos que lo componen, unos sobre otros, generan un ritmo, que se producirá a otras escalas, ello unido a las variaciones de sus formas y a la elección de sus materiales, ladrillo y madera, le confieren a la casa un carácter orgánico. El edificio se ancla a la tierra resolviéndose en diferentes niveles tras el estudio del lugar y su topografía. El resultado es una versión construida del paisaje, en la cual el edificio da forma al lugar y ensalza la experiencia del escenario natural. La unidad de las estructuras primitivas, parece estar presente. Constituye un ejemplo de la “La idea de Promenade de Asplund”, el proyecto ofrece diferentes recorridos, permitiendo su propia vivencia de la casa, que ofrece la posibilidad vital de decidir. El capítulo tercero trata sobre el pabellón de invitados de Niels Bohr de 1957, situado un área boscosa, en Tisvilde Hegn, fue el primer edificio del arquitecto danés Vilhelm Wohlert. Arraigado a la Tradición Danesa, representa una renovación basada en la absorción de influencias extranjeras: la Arquitectura Americana y la Tradición Japonesa. La caja de madera, posada sobre un terreno horizontal, tiene el carácter sensible de un organismo vivo, siempre cambiante según las variaciones de luz del día o temperatura. Cuando se abre, crea una prolongación del espacio interior, que se extiende a la naturaleza circundante, y se expande hacia el espacio exterior, permitiendo su movilización. Se establece una arquitectura de flujos. Hay un interés por la materia, su textura y el efecto emocional que emana. Las proporciones y dimensiones del edificio están reguladas por un módulo, que se ajusta a la medida del hombre, destacando la gran unidad del edificio. La llave se su efecto estético está en su armonía y equilibrio, que transmiten serenidad y belleza. El encuentro con la naturaleza es la lección más básica del proyecto, donde un mundo de relaciones es amable al ser humano. El capítulo cuarto, analiza el proyecto del Museo Louisiana de 1958, en Humlebæk, primer proyecto de la pareja de arquitectos daneses Jørgen Bo y Vilhelm Wohlert. La experiencia en California de Wohlert donde será visitado por Bo, será trascendental para el desarrollo de Louisiana, donde la identidad Danesa se fusiona con la asimilación de otras culturas, la arquitectura de Frank Lloyd Wright, la del área de la Bahía y la Tradición Japonesa principalmente. La idea del proyecto es la de una obra de arte integral: arquitectura, arte y paisaje, coexistirían en un mismo lugar. Diferentes recursos realzarán su carácter residencial, como el uso de los materiales propios de un entorno doméstico, la realización a la escala del hombre, el modo de usar la iluminación. Cubiertas planas que muestran su artificialidad, parecen flotar sobre galerías acristaladas, acentuarán la fuerza del plano horizontal y establecerán un recorrido en zig-zag de marcado ritmo acompasado. Ritmo que tiene que ver con la encarnación del pulso de la naturaleza, que se acompaña de juegos de luz, y de otras vibraciones materiales a diferentes escalas, imagen, que encuentra una analogía semejante en la cultura japonesa. Todo se coordina con la trama estructural, que conlleva a una construcción y proporción disciplinada. Louisiana atiende al principio de crecimiento de la naturaleza, con la que su conexión es profunda. Hay un dinamismo expresado por el despliegue del edificio, que evoca a algunos proyectos de la Tradición Japonesa. Los blancos muros tienen su propia identidad como formas en sí mismas, avanzan prolongándose fuera de la línea del vidrio, se mueven libremente siguiendo el orden estructural, acompañando al espacio que fluye, en contacto directo con la naturaleza que está en un continuo estado de flujos. Se da todo un mundo de relaciones, donde existe un dialogo entre el paisaje, arte y arquitectura. El capítulo quinto, se dedica a analizar la segunda casa del arquitecto danés Halldor Gunnløgsson, de 1959. Evoca a la Arquitectura Japonesa y Americana, pero es principalmente resultado de una fuerte voluntad y disciplina artística personal. La cubierta, plana, suspendida sobre una gran plataforma pavimentada, que continúa la sección del terreno construyendo de lugar, tiene una gran presencia y arroja una profunda sombra bajo ella. En el interior un espacio único, que se puede dividir eventualmente, discurre en torno a un cuerpo central. El espacio libre fluye, extendiéndose a través de la transparencia de sus ventanales a dos espacios contrapuestos: un patio ajardinado íntimo, que inspira calma y sosiego; y la naturaleza salvaje del mar que proyecta el color del cielo, ambos en constante estado de cambio. El proyecto se elabora de un modo rigurosamente formal, existiendo al mismo tiempo un perfecto equilibrio entre la abstracción de su estructura y su programa. La estructura de madera cuyo orden se extiende más allá de los límites de su perímetro, está formada por pórticos completos como elementos libres, queda expuesta, guardando una estrecha relación con el concepto de modernidad de Mies, equivalente a la arquitectura clásica. La preocupación por el efecto estético es máxima, nada es improvisado. Pero además la combinación de materiales y el juego de las texturas hay una cualidad táctil, cierto erotismo, que flota alrededor de ella. La precisión constructiva y su refinamiento se acercan a Mies. La experiencia del espacio arquitectónico es una vivencia global. La influencia de la arquitectura japonesa, es más conceptual que formal, revelada en un respeto por la naturaleza, la búsqueda del refinamiento a través de la moderación, la eliminación de los objetos innecesarios que distraen de la experiencia del lugar y la preocupación por la luz y la sombra, donde se establece cierto paralelismo con el oscuro mundo del invierno nórdico. Hay un entendimiento de que el espacio, en lugar de ser un objeto inmaterial definido por superficies materiales se entiende como interacciones dinámicas. El capítulo sexto. Propone un viaje para conocer algunas de las viviendas unifamiliares más interesantes que se construyeron en el periodo, que forman parte del sistema investigado. Del estudio comparado y orientado en varios temas, se obtienen diversa conclusiones propias del sistema estudiado. La maestría de la sustancia y la forma será una característica distintiva en Dinamarca, se demuestra que hay un acercamiento a la cultura de Oriente, conceptual y formal, y unos intereses comunes con cierta arquitectura Americana. Su lección nos sensibiliza hacia un sentido fortalecido de proporción, escala, materialidad, textura y peso, densidad del espacio, se valora lo táctil y lo visual, hay una sensibilidad hacia la naturaleza, hacia lo humano, hacia el paisaje, la integridad de la obra. ABSTRACT The thesis “1950 around the Louisiana Museum 1970” analyses several works related to domestic space, which were carried out between 1950 and 1970 in Denmark, a golden age of modern architecture. After the isolation and limitations brought about by the war that blighted Europe, young Danish architects were keen to experiment with ideas of an international origin, encouraged by different circumstances. They find the best field of rehearsal to be the domestic space. The best architecture of that period in Denmark should be understood as a system composed of different authors, who have in common with each other many more similarities than differences, thus complimenting each other. In the interests of understanding, the study of a range of figures and buildings is necessary so that this system, the research of which is still in its infancy, can be completed. The thesis proposes a journey of discovery through the names of some of those protagonists who were showcased through their work so that tradition and avant- garde could go hand in hand. The objective is to unveil the keys to Danish Modernity; to recognise, discover and revive the legacy of some of its protagonists in the domestic field whose lessons are seen as entirely of the present. For an architect, the taking on of modern contributions with both moderation and caution, with its intimate relationship with architectural tradition and its own craft, will be one of his hallmarks. With the study set against several projects and versions, one can derive common values among their authors. In the same way their affinities and differences in respect of the same issue emerge. This will allow an understanding of their measures in line with references and influences and enable the defining of the variables of their architectural spaces. The common line between the buildings selected will be their particular relationship with nature and the space with which they integrate. The façade, the place where the relationship between the interior and the landscape would be negotiated, wouldl be the discriminating element in a distinct way for each one of them. It is through each of these facades that this relationship would extend, and far beyond their physical perimeter. The investigation has been structured into six chapters, preceded by an introduction. The first chapter outlines and analyses the backgrounds, figures and buildings most relevant to the Danish Tradition. This is to facilitate the understanding and elucidation of some of the keys to its modernity in the field of architecture, which came about with the clear intention to discover its own identity and expression. This thriving modernity is characterized by its moderate assimilation with foreign cultures with a critical eye, and finds its roots anchored in architectural tradition and its own handcraft. It is forged in the emergence of a common ideal of enormous personality which today has come to be valued as an authentic contribution to the sphere from a culture that was formerly seen as on the peripheries. What will be demonstrated is the path taken by previous generations to these works and the debate that surrounds them. The sensibilities for both the vernacular and the classic, which at first glance may seem contradictory, will dominate the debate with the same veracity and respectability. The so-called third generation of Sigfried Giedion will revive the process between the classic and the vernacular, supported in spirit by the handcraft work and by tradition, with the objective of discovering the “truth” and the “original essence” of the architectural act. The second chapter analyzes the Varming house, built by Eva and Nils Koppel 1953, which is situated in a residential area of Gentofte. This reinterprets Asplund’s vision of an interior landscape extending to the exterior, where we see a break with the conventional sturdy brick shell of the 1930s. It is the most powerful example of the union of tradition and innovation in his their residential work. Their sober forms caught between Danish Functionalism and modernity are characterized by their abstraction and clean shapes which accentuate their prismatic and brutal geometry, The displacement of the parts of which they are composed, one over the other, generate a rhythm. This is produced to varying scales and is closely linked to its forms and the selection of materials – brick and wood – that confer an organic character to the house. The building is anchored to the earth, finding solution at different levels through the study of place and topography. The result is an adaption constructed out of the landscape, in which the building gives form to the place and celebrates the experience of the natural setting. The unity of primitive structures appears to be present. It constitutes an example of “Asplund’s Promenade Idea”. Different routes of exploration within are available to the visitor, allowing for one’s own personal experience of the house, allowing in turn for the vital chance to decide. The third chapter deals with Niels Bohr’s guest pavilion. Built in 1957, it is situated in a wooded area of Tisvilde Hegn and was the architect Vilhelm Wohlert’s first building. Rooted in the Danish Tradition, it represents a renewal based on the absorption of foreign influences: American architecture and the Japanese tradition. The wooden box, perched atop a horizontal terrain, possesses the sensitive character of the living organism, ever-changing in accordance with the variations in daylight and temperature. When opened up, it creates an elongation of the interior space which extends into the surrounding nature and it expands towards the exterior space, allowing for its mobilisation. It establishes an architecture of flux. There is interest in the material, its texture and the emotional effect it inspires. The building’s proportions and dimensions are regulated by a module, which is adjusted by hand, bringing out the great unity of the building. The key to its aesthetic effect is its harmony and equilibrium, which convey serenity and beauty. The meeting with nature is the most fundamental lesson of the project, where a world of relationships softens the personality of the human being. The fourth chapter analyzes the Louisiana Museum project of 1958 in 1958. It was the first project of the Danish architects Jørgen Bo and Vilhelm Wohlert. Wohlert’s experience in California where he was visited by Bo would be essential to the development of Louisiana, where the Danish identity is fused in assimilation with other cultures, the architecture of Frank Lloyd Wright, that of the Bahía area and principally the Japanese tradition. The idea of the project was for an integrated work of art: architecture, art and landscape, which would coexist in the same space. A range of different resources would realize the residential character, such as the use of materials taken from a domestic environment, the attainment of human scale and the manner in which light was used. Flat roof plans that show their artificiality and appear to float over glassed galleries. They accentuate the strength of the horizontal plan and establish a zigzag route of marked and measured rhythm. It is a rhythm that has to do with the incarnation of nature’s pulse, which is accompanied with plays of light, as well as material vibrations of different scales, imagery which uncovers a parallel analogy with Japanese culture. Everything is coordinated along a structural frame, which involves a disciplined construction and proportion. Louisiana cherishes nature’s principle of growth, to which its connection is profound. Here is a dynamism expressed through the disposition of the building, which evokes in some projects the Japanese tradition. The white walls possess their own identity as forms in their own right. They advance, extending beyond the line of glass, moving freely along the structural line, accompanying a space that flows and in direct contact with nature that is itself in a constant state of flux. It creates a world of relationships, where dialogue exists between the landscape, art and architecture. The fifth chapter is dedicated to analyzing the Danish architect Halldor Gunnløgsson’s second house, built in 1959. It evokes both Japanese and American architecture but is principally the result of a strong will and personal artistic discipline. The flat roof suspended above a large paved platform – itself continuing the constructed terrain of the place – has great presence and casts a heavy shadow beneath. In the interior, a single space, which can at length be divided and which flows around a central space. The space flows freely, extending through the transparency of its windows which give out onto two contrasting locations: an intimate garden patio, inspiring calm and tranquillity, and the wild nature of the sea which projects the colour of sky, both in a constant state of change. The project is realized in a rigorously formal manner. A perfect balance exists between the abstraction of his structure and his project. The wooden structure, whose order extends beyond the limits of its perimeter, is formed of complete porticos of free elements. It remains exposed, maintaining a close relationship with Mies’ concept of modernity, analogous to classical architecture. The preoccupation with the aesthetic effect is paramount and nothing is improvised. But in addition to this - the combination of materials and the play of textures - there is a tactile quality, a certain eroticism, which lingers all about. The constructive precision and its refinement are close to Mies. The experience of the architectural space is universal. The influence of Japanese architecture, more conceptual than formal, is revealed in a respect for nature. It can be seen in the search for refinement through moderation, the elimination of the superfluous object that distract from the experience of place and the preoccupation with light and shade, where a certain parallel with the dark world of the Nordic winter is established. There is an understanding that space, rather than being an immaterial object defined by material surfaces, extends instead as dynamic interactions. The sixth chapter. This proposes a journey to discover some of the unfamiliar residences of most interest which were constructed in the period, and which form part of the system being investigated. Through the study of comparison and one which is geared towards various themes, diverse conclusions are drawn regarding the system being researched. The expertise in substance and form will be a distinctive characteristic in Denmark, demonstrating an approach to the culture of the Orient, both conceptual and formal, and some common interests in certain American architecture. Its teachings sensitize us to a strengthened sense of proportion, scale, materiality, texture and weight and density of space. It values both the tactile and the visual. There is a sensitivity to nature, to the human, to the landscape and to the integrity of the work.

Induced radioisotopes in a linac treatment hall

When linacs operate above 8MV an undesirable neutron field is produced whose spectrum has three main components: the direct spectrum due to those neutrons leaking out from the linac head, the scattered spectrum due to neutrons produced in the head that collides with the nuclei in the head losing energy and the third spectrum due to room-return effect. The third category of spectrum has mainly epithermal and thermal neutrons being constant at any location in the treatment hall. These neutrons induce activation in the linac components, the concrete walls and in the patient body. Here the induced radioisotopes have been identified in concrete samples located in the hall and in one of the wedges. The identification has been carried out using a gamma-ray spectrometer.

Development of a hand-gesture recognition system for human-computer interaction

The aim of this Master Thesis is the analysis, design and development of a robust and reliable Human-Computer Interaction interface, based on visual hand-gesture recognition. The implementation of the required functions is oriented to the simulation of a classical hardware interaction device: the mouse, by recognizing a specific hand-gesture vocabulary in color video sequences. For this purpose, a prototype of a hand-gesture recognition system has been designed and implemented, which is composed of three stages: detection, tracking and recognition. This system is based on machine learning methods and pattern recognition techniques, which have been integrated together with other image processing approaches to get a high recognition accuracy and a low computational cost. Regarding pattern recongition techniques, several algorithms and strategies have been designed and implemented, which are applicable to color images and video sequences. The design of these algorithms has the purpose of extracting spatial and spatio-temporal features from static and dynamic hand gestures, in order to identify them in a robust and reliable way. Finally, a visual database containing the necessary vocabulary of gestures for interacting with the computer has been created.

Jujube fruit water relations during fruit maturation stage under different water deficit conditions

The fruit maturation stage is considered the optimal phenological stage for implementing water deficitin jujube (Zizyphus jujuba Mill.), since a low, moderate or severe water deficit at this time has no effect onyield, fruit volume or eating quality. However, no information exists at fruit water relations level on themechanisms developed by Z. jujuba to confront drought. The purpose of the present study was to increaseour understanding of the relationship between leaf and fruit water relations of jujube plants under dif-ferent irrigation conditions during fruit maturation, paying special attention to analysing whether fruitsize depends on fruit turgor. For this, adult jujube trees (cv. Grande de Albatera) were subjected to fiveirrigation treatments. Control plants (T0) were irrigated daily above their crop water requirements inorder to attain non-limiting soil water conditions in 2012 and 2013. T1 plants were subjected to deficitirrigation throughout the 2012 season, according to the criteria frequently used by the growers in thearea. T2 (2012), T3 and T4 (2013) were irrigated as T0 except during fruit maturation, in which irrigationwas withheld for 32, 17 and 24 days, respectively. The results indicated that the jujube fruit maturationperiod was clearly sensitive to water deficit. During most of this stage water could enter the fruits viathe phloem rather than via the xylem. From the beginning of water withholding to when maximumwater stress levels were achieved, fruit and leaf turgor were maintained in plants under water deficit.However, a direct relation between turgor and fruit size was not found in jujube fruits, which could bedue to an enhancement of a cell elasticity mechanism (elastic adjustment) which maintains fruit turgorby reducing fruit cells size or to the fact that jujube fruit growth depends on the fruit growth-effectiveturgor rather than just turgor pressure.

Interactive Graphic Simulation: An Advanced Methodology to Improve the Teaching-Learning Process in Nuclear Engineering Education and Training

Nowadays, computer simulators are becoming basic tools for education and training in many engineering fields. In the nuclear industry, the role of simulation for training of operators of nuclear power plants is also recognized of the utmost relevance. As an example, the International Atomic Energy Agency sponsors the development of nuclear reactor simulators for education, and arranges the supply of such simulation programs. Aware of this, in 2008 Gas Natural Fenosa, a Spanish gas and electric utility that owns and operate nuclear power plants and promotes university education in the nuclear technology field, provided the Department of Nuclear Engineering of Universidad Politécnica de Madrid with the Interactive Graphic Simulator (IGS) of “José Cabrera” (Zorita) nuclear power plant, an industrial facility whose commercial operation ceased definitively in April 2006. It is a state-of-the-art full-scope real-time simulator that was used for training and qualification of the operators of the plant control room, as well as to understand and analyses the plant dynamics, and to develop, qualify and validate its emergency operating procedures.

High-quality real-time temporal segmentation tool for video editing software

The increasing use of video editing software has resulted in a necessity for faster and more efficient editing tools. Here, we propose a lightweight high-quality video indexing tool that is suitable for video editing software.

Temporal segmentation tool for high-quality real time video editing software

The increasing use of video editing software requires faster and more efficient editing tools. As a first step, these tools perform a temporal segmentation in shots that allows a later building of indexes describing the video content. Here, we propose a novel real-time high-quality shot detection strategy, suitable for the last generation of video editing software requiring both low computational cost and high quality results. While abrupt transitions are detected through a very fast pixel-based analysis, gradual transitions are obtained from an efficient edge-based analysis. Both analyses are reinforced with a motion analysis that helps to detect and discard false detections. This motion analysis is carried out exclusively over a reduced set of candidate transitions, thus maintaining the computational requirements demanded by new applications to fulfill user needs.

Experimental Prototype Merging Stereo Panoramic Video and Interactive 3D Content in a 5-sided CAVETM

Immersion and interaction have been identified as key factors influencing the quality of experience in stereoscopic video systems. An experimental prototype designed to explore the influence of these factors in 3D video applications is described here1. The focus is on the real-time insertion algorithm of new 3D models into the original video streams. Using this algorithm, our prototype is aimed to explore a new interaction paradigm ? similar to the augmented reality approach ? with 3D video applications.

AMELIE: Authoring Multimedia-Enhanced Learning Interactive Environment for e-Health Contents

This paper presents the AMELIE Authoring Tool for e-health applications. AMELIE provides the means for creating video-based contents with a focus on e-learning and telerehabilitation processes. The main core of AMELIE lies in the efficient exploitation of raw multimedia resources, which may be already available at clinical centers or recorded ad hoc for learning purposes by health professionals. Three real use cases scenarios involving different target users are presented: (1) cognitive skills? training of surgeons in minimally invasive surgery (medical professionals), (2) training of informal carers for elderly home assistance and (3) cognitive rehabilitation of patients with acquired brain injury. Preliminary validation in the field of surgery hints at the potential of AMELIE; and its versatility in different medical applications is patent from the use cases described. Regardless, new validation studies are planned in the three main application areas identified in this work.

Development and implementation of a virtual laboratory for training process improvement in the mechanics of continuous media

The project arises from the need to develop improved teaching methodologies in field of the mechanics of continuous media. The objective is to offer the student a learning process to acquire the necessary theoretical knowledge, cognitive skills and the responsibility and autonomy to professional development in this area. Traditionally the teaching of the concepts of these subjects was performed through lectures and laboratory practice. During these lessons the students attitude was usually passive, and therefore their effectiveness was poor. The proposed methodology has already been successfully employed in universities like University Bochum, Germany, University the South Australia and aims to improve the effectiveness of knowledge acquisition through use by the student of a virtual laboratory. This laboratory allows to adapt the curricula and learning techniques to the European Higher Education and improve current learning processes in the University School of Public Works Engineers -EUITOP- of the Technical University of Madrid -UPM-, due there are not laboratories in this specialization. The virtual space is created using a software platform built on OpenSim, manages 3D virtual worlds, and, language LSL -Linden Scripting Language-, which imprints specific powers to objects. The student or user can access this virtual world through their avatar -your character in the virtual world- and can perform practices within the space created for the purpose, at any time, just with computer with internet access and viewfinder. The virtual laboratory has three partitions. The virtual meeting rooms, where the avatar can interact with peers, solve problems and exchange existing documentation in the virtual library. The interactive game room, where the avatar is has to resolve a number of issues in time. And the video room where students can watch instructional videos and receive group lessons. Each audiovisual interactive element is accompanied by explanations framing it within the area of knowledge and enables students to begin to acquire a vocabulary and practice of the profession for which they are being formed. Plane elasticity concepts are introduced from the tension and compression testing of test pieces of steel and concrete. The behavior of reticulated and articulated structures is reinforced by some interactive games and concepts of tension, compression, local and global buckling will by tests to break articulated structures. Pure bending concepts, simple and composite torsion will be studied by observing a flexible specimen. Earthquake resistant design of buildings will be checked by a laboratory test video.
