La protección civil municipal: análisis de los distintos tipos de gestión y propuesta metodológica de planificación

Mediante la elaboración de esta tesis doctoral se pretende diseñar un sistema para la realización del plan de autoprotección en industrias con riesgo de incendio dentro de un polígono industrial. Para desarrollar esta línea de investigación se realizará una investigación cartográfica así como un reconocimiento visual de las distintas empresas industriales, de actividades heterogéneas, seleccionadas por su emplazamiento y condiciones. Este tipo de industria es esencial en el sistema económico nacional, ya que dota de recursos y servicios al tejido social, además de tener una relación directa con la generación de riqueza y por tanto incide de forma positiva en el empleo de cualquier región. Estas razones y otras son determinantes para fomentar el progreso, si bien nunca a expensas de la seguridad de los empleados que hacen posible la línea de producción así como de los posibles viandantes que transcurran por la zona de impacto en caso de incidentes como por ejemplo un incendio que afecte a cualquiera de los locales y/o empresas que se emplazen en los denominados polígonos industriales. La tesis incluye trabajos experimentales de los que se extraen recomendaciones y conclusiones encaminadas a la optimización de la instrumentalización utilizada, las técnicas de observación, diseño y cálculo necesarias que determinarán el acercamiento al método propuesto para nuestra valoración del riesgo por incendio. Las posibles emergencias que pueden darse a nivel de industrias localizadas en polígonos industriales son diversas y numerosas. De todas ellas se elige abordar el caso de “incendio” por su casuística más numerosa. No obstante, la planificación orientada desde el prisma de la investigación de esta tesis puede estenderse a cualquier otro riesgo, lo que se aportará como líneas futuras de investigación. Las aproximaciones y etapas de los trabajos que forman parte de esta investigación se han integrado en cada capítulo y son las siguientes: En primer lugar un capítulo de Introducción, en el que se realiza una reflexión justificada de la elección del tema tratado, se formula la hipótesis de partida y se enumeran los distintos objetivos que se pretenden alcanzar. En el segundo capítulo, titulado Aspectos de la Protección Civil en la Constitución Española de 1978, se ha realizado un estudio exhaustivo de la Constitución en todo lo relacionado con el ámbito de la protección, haciendo especial énfasis en las distintas competencias según el tipo de administración que corresponda en cada caso, así como las obligaciones y deberes que corresponden a los ciudadanos en caso de catástrofe. Así mismo se analizan especialmente los casos de Guerra y el estado de Alarma. En el tercer capítulo, titulado Repuesta de las administraciones públicas ante emergencias colectivas, se trata de formular el adecuado sistema de repuesta que sería preciso para tratar de mitigar desastres y catástrofes. Se analizan los distintos sistemas de gestión de emergencias constatando en cada caso los pros y los contras de cada uno. Se pretende con ello servir de ayuda en la toma de decisiones de manera coherente y racional. El capítulo cuarto, denominado Planes Locales de emergencia. Estudio en las distintas administraciones, se ha pormenorizado en la presentación así como puesta en funcionamiento de los planes, comparando los datos obtenidos entre ellos para concluir en un punto informativo que nos lleva a la realidad de la planificación. Para la realización y desarrollo de los capítulos 5 y 6, llamados Análisis de la Norma Básica de Autoprotección y Métodos de evaluación del riesgo de Incendio, se estudia la normativa actual en autoprotección prestando atención a los antecedentes históricos así como a todas las figuras que intervienen en la misma. Se analizan los distintos métodos actuales para la valoración del riesgo por incendio en industrias. Este aspecto es de carácter imprescindible en la protección civil de los ciudadanos pero también es de especial importancia en las compañías aseguradoras. En el capítulo 7, Propuesta metodológica, se propone y justifica la necesidad de establecer una metodología de estudio para estos casos de riesgo por incendio en industrias para así, acortar el tiempo de respuesta de los servicios de emergencia hasta la zona, así como dotar de información imprescindible sobre el riesgo a trabajadores y transeúntes. El último capítulo se refiere a las Conclusiones, donde se establecen y enuncian una serie de conclusiones y resultados como consecuencia de la investigación desarrollada, para finalizar esta tesis doctoral enunciando posibles desarrollos y líneas de investigación futuros.

Comparación de un nuevo método de aceleración de análisis dinámicos con métodos de reducción de modelos

La dinámica estructural estudia la respuesta de una estructura ante cargas o fenómenos variables en el tiempo. En muchos casos, estos fenómenos requieren realizar análisis paramétricos de la estructura considerando una gran cantidad de configuraciones de diseño o modificaciones de la estructura. Estos cambios, ya sean en fases iniciales de diseño o en fases posteriores de rediseño, alteran las propiedades físicas de la estructura y por tanto del modelo empleado para su análisis, cuyo comportamiento dinámico se modifica en consecuencia. Un caso de estudio de este tipo de modificaciones es la supervisión de la integridad estructural, que trata de identificar la presencia de daño estructural y prever el comportamiento de la estructura tras ese daño, como puede ser la variación del comportamiento dinámico de la estructura debida a una delaminación, la aparición o crecimiento de grieta, la debida a la pérdida de pala sufrida por el motor de un avión en vuelo, o la respuesta dinámica de construcciones civiles como puentes o edificios frente a cargas sísmicas. Si a la complejidad de los análisis dinámicos requeridos en el caso de grandes estructuras se añade la variación de determinados parámetros en busca de una respuesta dinámica determinada o para simular la presencia de daños, resulta necesario la búsqueda de medios de simplificación o aceleración del conjunto de análisis que de otra forma parecen inabordables tanto desde el punto de vista del tiempo de computación, como de la capacidad requerida de almacenamiento y manejo de grandes volúmenes de archivos de datos. En la presente tesis doctoral se han revisado los métodos de reducción de elementos .nitos más habituales para análisis dinámicos de grandes estructuras. Se han comparado los resultados de casos de estudio de los métodos más aptos, para el tipo de estructuras y modificaciones descritas, con los resultados de aplicación de un método de reducción reciente. Entre los primeros están el método de condensación estática de Guyan extendido al caso con amortiguamiento no proporcional y posteriores implementaciones de condensaciones dinámicas en diferentes espacios vectoriales. El método de reducción recientemente presentado se denomina en esta tesis DACMAM (Dynamic Analysis in Complex Modal space Acceleration Method), y consiste en el análisis simplificado que proporciona una solución para la respuesta dinámica de una estructura, calculada en el espacio modal complejo y que admite modificaciones estructurales. El método DACMAM permite seleccionar un número reducido de grados de libertad significativos para la dinámica del fenómeno que se quiere estudiar como son los puntos de aplicación de la carga, localizaciones de los cambios estructurales o puntos donde se quiera conocer la respuesta, de forma que al implementar las modificaciones estructurales, se ejecutan los análisis necesarios sólo de dichos grados de libertad sin pérdida de precisión. El método permite considerar alteraciones de masa, rigidez, amortiguamiento y la adición de nuevos grados de libertad. Teniendo en cuenta la dimensión del conjunto de ecuaciones a resolver, la parametrización de los análisis no sólo resulta posible, sino que es también manejable y controlable gracias a la sencilla implementación del procedimiento para los códigos habituales de cálculo mediante elementos .nitos. En el presente trabajo se muestra la bondad y eficiencia del método en comparación con algunos de los métodos de reducción de grandes modelos estructurales, verificando las diferencias entre sí de los resultados obtenidos y respecto a la respuesta real de la estructura, y comprobando los medios empleados en ellos tanto en tiempo de ejecución como en tamaño de ficheros electrónicos. La influencia de los diversos factores que se tienen en cuenta permite identificar los límites y capacidades de aplicación del método y su exhaustiva comparación con los otros procedimientos. ABSTRACT Structural dynamics studies the response of a structure under loads or phenomena which vary over time. In many cases, these phenomena require the use of parametric analyses taking into consideration several design configurations or modifications of the structure. This is a typical need in an engineering o¢ ce, no matter the structural design is in early or final stages. These changes modify the physical properties of the structure, and therefore, the finite element model to analyse it. A case study, that exempli.es this circumstance, is the structural health monitoring to predict the variation of the dynamical behaviour after damage, such as a delaminated structure, a crack onset or growth, an aircraft that suffers a blade loss event or civil structures (buildings or bridges) under seismic loads. Not only large structures require complex analyses to appropriately acquire an accurate solution, but also the variation of certain parameters. There is a need to simplify the analytical process, in order to bring CPU time, data .les, management of solutions to a reasonable size. In the current doctoral thesis, the most common finite element reduction methods for large structures are reviewed. Results of case studies are compared between a recently proposed method, herein named DACMAM (Dynamic Analysis in Complex Modal space Acceleration Method), and different condensation methods, namely static or Guyan condensation and dynamic condensation in different vectorial spaces. All these methods are suitable for considering non-classical damping. The reduction method DACMAM consist of a structural modification in the complex modal domain which provides a dynamic response solution for the reduced models. This process allows the selection of a few degrees of freedom that are relevant for the dynamic response of the system. These d.o.f. are the load application points, relevant structural points or points in which it is important to know the response. Consequently, an analysis with structural modifications implies only the calculation of the dynamic response of the selected degrees of freedom added, but with no loss of information. Therefore, mass, stiffness or damping modifications are easily considered as well as new degrees of freedom. Taking into account the size of the equations to be solved, the parameterization of the dynamic solutions is not only possible, but also manageable and controllable due to the easy implementation of the procedure in the standard finite element solvers. In this thesis, the proposed reduction method for large structural models is compared with other published model order reduction methods. The comparison shows and underlines the efficiency of the new method, and veri.es the differences in the response when compared with the response of the full model. The CPU time, the data files and the scope of the parameterization are also addressed.

Evaluación de nuevos dispositivos en la interacción de niños con necesidades específicas de apoyo educativo

Durante la realización de este trabajo de fin de grado se realizará el diseño y desarrollo de un juego orientado a niños con necesidades específicas de apoyo educativo. Este grupo de usuarios repercute en el diseño de los elementos del juego los cuales han de ser simples, sin distracciones, textos de ayuda claros y bien definidos, alto contraste en los elementos, ayuda textual y visual, selección de colores evitando referencias conocidas (rojo como referencia a peligro); y una serie de patrones más, que se han tenido que tener en cuenta. El juego es compatible con distintos dispositivos (teclado, pantalla táctil y Kinect), por lo que, como parte del análisis previo, se ha tenido que ver el trabajo realizado anteriormente referente a estos dispositivos (un reconocedor de gestos de pantalla táctil y un reconocedor de gestos de Kinect), que realizaron otros alumnos. En este sentido y como parte de este y otros proyectos, se han tenido que mejorar o complementar las implementaciones de estos reconocedores. Además se han tenido que definir los distintos gestos o teclas, que producirán respuestas en el juego. Como parte de la interacción de los usuarios con el juego mediante los distintos dispositivos, el juego se ha diseñado de tal forma, que es capaz de capturar ciertos datos de forma automática (precisión al realizar un gesto en pantalla, realización de un gesto incorrecto, etc.). Además como soporte adicional a la obtención de datos con el juego, se han planteado distintos formularios (según el dispositivo), los cuales aportan información que el juego no es capaz de recoger de forma automática, y que serán capturados por el pedagogo. Toda esta información recogida será parte de un modelo de datos el cual, en un futuro, servirá para analizar el comportamiento de este grupo de usuarios frente a los distintos dispositivos analizados. Viendo sus ventajas y desventajas tanto en tiempo de respuesta, curva de aprendizaje, dificultad de realización de los gestos, etc.---ABSTRACT---This thesis project will showcase the design and development of a game oriented towards children with special educational needs. This group impacts the design of the game elements, which have to be simple and avoid distractions. There must be clear and well defined help text, high contrast in the elements, text and visual help, color selection that avoids known references (red as a reference to danger), and more series of patterns. The game is compatible with various devices (keyboard, touchscreen and Kinect), by which, as part of the preliminary analysis, the work previously conducted by other students concerning these devices was researched (a touch screen gesture recognizer and a Kinect gesture recognizer). In this regard, and as part of this and other projects, the use of these recognizers must be improved or complemented. In addition the different gestures or keys that will produce answers in the game must be defined. As part of the users’ interaction with the game through the various devices, the game is designed in such a way that it is able to capture certain data automatically (precision making a gesture to the screen, making an improper gesture, etc.). Also as additional support to obtain data with the game, different forms were used (depending on the device), which provide information that the game is not able to pick up automatically, and that will be caught by the teacher. The information collected will be part of a data model which, in the future, will serve to analyze the behavior of this user group with the various devices analyzed. Seeing their advantages and disadvantages both in response time, learning curve and difficulty of making gestures, etc.

Design and Optimization of Power Delivery and Distribution Systems Using Evolutionary Computation Techniques

Nowadays computing platforms consist of a very large number of components that require to be supplied with diferent voltage levels and power requirements. Even a very small platform, like a handheld computer, may contain more than twenty diferent loads and voltage regulators. The power delivery designers of these systems are required to provide, in a very short time, the right power architecture that optimizes the performance, meets electrical specifications plus cost and size targets. The appropriate selection of the architecture and converters directly defines the performance of a given solution. Therefore, the designer needs to be able to evaluate a significant number of options in order to know with good certainty whether the selected solutions meet the size, energy eficiency and cost targets. The design dificulties of selecting the right solution arise due to the wide range of power conversion products provided by diferent manufacturers. These products range from discrete components (to build converters) to complete power conversion modules that employ diferent manufacturing technologies. Consequently, in most cases it is not possible to analyze all the alternatives (combinations of power architectures and converters) that can be built. The designer has to select a limited number of converters in order to simplify the analysis. In this thesis, in order to overcome the mentioned dificulties, a new design methodology for power supply systems is proposed. This methodology integrates evolutionary computation techniques in order to make possible analyzing a large number of possibilities. This exhaustive analysis helps the designer to quickly define a set of feasible solutions and select the best trade-off in performance according to each application. The proposed approach consists of two key steps, one for the automatic generation of architectures and other for the optimized selection of components. In this thesis are detailed the implementation of these two steps. The usefulness of the methodology is corroborated by contrasting the results using real problems and experiments designed to test the limits of the algorithms.

Response threshold models, stochastic learning automata and ant colony optimization-based decentralized self-coordination algorithms for heterogeneous multi-tasks distribution in multi-robot systems

In recent decades, there has been an increasing interest in systems comprised of several autonomous mobile robots, and as a result, there has been a substantial amount of development in the eld of Articial Intelligence, especially in Robotics. There are several studies in the literature by some researchers from the scientic community that focus on the creation of intelligent machines and devices capable to imitate the functions and movements of living beings. Multi-Robot Systems (MRS) can often deal with tasks that are dicult, if not impossible, to be accomplished by a single robot. In the context of MRS, one of the main challenges is the need to control, coordinate and synchronize the operation of multiple robots to perform a specic task. This requires the development of new strategies and methods which allow us to obtain the desired system behavior in a formal and concise way. This PhD thesis aims to study the coordination of multi-robot systems, in particular, addresses the problem of the distribution of heterogeneous multi-tasks. The main interest in these systems is to understand how from simple rules inspired by the division of labor in social insects, a group of robots can perform tasks in an organized and coordinated way. We are mainly interested on truly distributed or decentralized solutions in which the robots themselves, autonomously and in an individual manner, select a particular task so that all tasks are optimally distributed. In general, to perform the multi-tasks distribution among a team of robots, they have to synchronize their actions and exchange information. Under this approach we can speak of multi-tasks selection instead of multi-tasks assignment, which means, that the agents or robots select the tasks instead of being assigned a task by a central controller. The key element in these algorithms is the estimation ix of the stimuli and the adaptive update of the thresholds. This means that each robot performs this estimate locally depending on the load or the number of pending tasks to be performed. In addition, it is very interesting the evaluation of the results in function in each approach, comparing the results obtained by the introducing noise in the number of pending loads, with the purpose of simulate the robot's error in estimating the real number of pending tasks. The main contribution of this thesis can be found in the approach based on self-organization and division of labor in social insects. An experimental scenario for the coordination problem among multiple robots, the robustness of the approaches and the generation of dynamic tasks have been presented and discussed. The particular issues studied are: Threshold models: It presents the experiments conducted to test the response threshold model with the objective to analyze the system performance index, for the problem of the distribution of heterogeneous multitasks in multi-robot systems; also has been introduced additive noise in the number of pending loads and has been generated dynamic tasks over time. Learning automata methods: It describes the experiments to test the learning automata-based probabilistic algorithms. The approach was tested to evaluate the system performance index with additive noise and with dynamic tasks generation for the same problem of the distribution of heterogeneous multi-tasks in multi-robot systems. Ant colony optimization: The goal of the experiments presented is to test the ant colony optimization-based deterministic algorithms, to achieve the distribution of heterogeneous multi-tasks in multi-robot systems. In the experiments performed, the system performance index is evaluated by introducing additive noise and dynamic tasks generation over time.

Response threshold models and stochastic learning automata for self-coordination of heterogeneous multi-task distribution in multi-robot systems.

This paper focuses on the general problem of coordinating multiple robots. More specifically, it addresses the self-selection of heterogeneous specialized tasks by autonomous robots. In this paper we focus on a specifically distributed or decentralized approach as we are particularly interested in a decentralized solution where the robots themselves autonomously and in an individual manner, are responsible for selecting a particular task so that all the existing tasks are optimally distributed and executed. In this regard, we have established an experimental scenario to solve the corresponding multi-task distribution problem and we propose a solution using two different approaches by applying Response Threshold Models as well as Learning Automata-based probabilistic algorithms. We have evaluated the robustness of the algorithms, perturbing the number of pending loads to simulate the robot’s error in estimating the real number of pending tasks and also the dynamic generation of loads through time. The paper ends with a critical discussion of experimental results.

Modelling uncertainty of flood quantile estimation at ungauged sites by Bayesian networks

Prediction at ungauged sites is essential for water resources planning and management. Ungauged sites have no observations about the magnitude of floods, but some site and basin characteristics are known. Regression models relate physiographic and climatic basin characteristics to flood quantiles, which can be estimated from observed data at gauged sites. However, these models assume linear relationships between variables Prediction intervals are estimated by the variance of the residuals in the estimated model. Furthermore, the effect of the uncertainties in the explanatory variables on the dependent variable cannot be assessed. This paper presents a methodology to propagate the uncertainties that arise in the process of predicting flood quantiles at ungauged basins by a regression model. In addition, Bayesian networks were explored as a feasible tool for predicting flood quantiles at ungauged sites. Bayesian networks benefit from taking into account uncertainties thanks to their probabilistic nature. They are able to capture non-linear relationships between variables and they give a probability distribution of discharges as result. The methodology was applied to a case study in the Tagus basin in Spain.
