Radar technologies have been developed to improve the efficiency when detecting targets. Radar is a system composed by several devices connected and working together. Depending on the type of radar, the improvements are focused on different functionalities of the radar. One of the most important devices composing a radar is the antenna, that sends the radio-frequency signal to the space in order to detect targets. This project is focused on a specific type of radar called phased array radar. This type of radar is characterized by its antenna, which consist on a linear array of radiating elements, in this particular case, eight dipoles working at the frequency band S. The main advantage introduced by the phased array antenna is that using the fundamentals of arrays, the directivity of the antenna can change by shifting the phase of the signal at the input of each radiating element. This can be done using phase shifters. Phase shifter consists on a device which produces a phase shift in the radio-frequency input signal depending on a control DC voltage. Using a phased array antenna allows changing the directivity of the antenna without a mechanical rotating system. The objective of this project is to design the feed network and the bias network of the phased antenna. The feed network consists on a parallel-fed network composed by power dividers that sends the radio-frequency signal from the source to each radiating element of the antenna. The bias network consists on a system that generates the control DC voltages supplied to the phase shifters in order to change the directivity. The architecture of the bias network is composed by a software, implemented in Matlab and run in a laptop which is connected to a micro-controller by a serial communication port. The software calculates the control DC voltages needed to obtain a determined directivity or scan angle. These values are sent by the serial communication port to the micro-controller as data. Then the micro-controller generates the desired control DC voltages and supplies them to the phase shifters. In this project two solutions for bias network are designed. Each one is tested and final conclusions are obtained to determine the advantages and disadvantages. Finally a graphic user interface is developed in order to make the system easy to use. RESUMEN. Las tecnologías empleadas por lo dispositivos radar se han ido desarrollando para mejorar su eficiencia y usabilidad. Un radar es un sistema formado por varios subsistemas conectados entre sí. Por lo que dependiendo del tipo de radar las mejoras se centran en los subsistemas correspondientes. Uno de los elementos más importantes de un radar es la antena. Esta se emplea para enviar la señal de radiofrecuencia al espacio y así poder detectar los posibles obstáculos del entorno. Este proyecto se centra en un tipo específico de radar llamado phased array radar. Este tipo de radar se caracteriza por la antena que es un array de antenas, en concreto para este proyecto se trata de un array lineal de ocho dipolos en la banda de frequencia S. El uso de una antena de tipo phased array supone una ventaja importante. Empleando los fundamentos de radiación aplicado a array de antenas se obtiene que la directividad de la antena puede ser modificada. Esto se consigue aplicando distintos desfasajes a la señal de radiofrecuencia que alimenta a cada elemento del array. Para aplicar los desfasajes se emplea un desplazador de fase, este dispositivo aplica una diferencia de fase a su salida con respecto a la señal de entrada dependiendo de una tensión continua de control. Por tanto el empleo de una antena de tipo phased array supone una gran ventaja puesto que no se necesita un sistema de rotación para cambiar la directividad de la antena. El objetivo principal del proyecto consiste en el diseño de la red de alimentación y la red de polarización de la antena de tipo phased array. La red de alimentación consiste en un circuito pasivo que permite alimentar a cada elemento del array con la misma cantidad de señal. Dicha red estará formada por divisores de potencia pasivos y su configuración será en paralelo. Por otro lado la red de polarización consiste en el diseño de un sistema automático que permite cambiar la directividad de la antena. Este sistema consiste en un programa en Matlab que es ejecutado en un ordenador conectado a un micro-controlador mediante una comunicación serie. El funcionamiento se basa en calcular las tensiones continuas de control, que necesitan los desplazadores de fase, mediante un programa en Matlab y enviarlos como datos al micro-controlador. Dicho micro-controlador genera las tensiones de control deseadas y las proporciona a cada desplazador de fase, obteniendo así la directividad deseada. Debido al amplio abanico de posibilidades, se obtienen dos soluciones que son sometidas a pruebas. Se obtienen las ventajas y desventajas de cada una. Finalmente se implementa una interfaz gráfica de usuario con el objetivo de hacer dicho sistema manejable y entendible para cualquier usuario.

Background DCE@urLAB is a software application for analysis of dynamic contrast-enhanced magnetic resonance imaging data (DCE-MRI). The tool incorporates a friendly graphical user interface (GUI) to interactively select and analyze a region of interest (ROI) within the image set, taking into account the tissue concentration of the contrast agent (CA) and its effect on pixel intensity. Results Pixel-wise model-based quantitative parameters are estimated by fitting DCE-MRI data to several pharmacokinetic models using the Levenberg-Marquardt algorithm (LMA). DCE@urLAB also includes the semi-quantitative parametric and heuristic analysis approaches commonly used in practice. This software application has been programmed in the Interactive Data Language (IDL) and tested both with publicly available simulated data and preclinical studies from tumor-bearing mouse brains. Conclusions A user-friendly solution for applying pharmacokinetic and non-quantitative analysis DCE-MRI in preclinical studies has been implemented and tested. The proposed tool has been specially designed for easy selection of multi-pixel ROIs. A public release of DCE@urLAB, together with the open source code and sample datasets, is available at http://www.die.upm.es/im/archives/DCEurLAB/ webcite.

Modern sensor technologies and simulators applied to large and complex dynamic systems (such as road traffic networks, sets of river channels, etc.) produce large amounts of behavior data that are difficult for users to interpret and analyze. Software tools that generate presentations combining text and graphics can help users understand this data. In this paper we describe the results of our research on automatic multimedia presentation generation (including text, graphics, maps, images, etc.) for interactive exploration of behavior datasets. We designed a novel user interface that combines automatically generated text and graphical resources. We describe the general knowledge-based design of our presentation generation tool. We also present applications that we developed to validate the method, and a comparison with related work.

El objetivo principal alrededor del cual se desenvuelve este proyecto es el desarrollo de un sistema de reconocimiento facial. Entre sus objetivos específicos se encuentran: realizar una primera aproximación sobre las técnicas de reconocimiento facial existentes en la actualidad, elegir una aplicación donde pueda ser útil el reconocimiento facial, diseñar y desarrollar un programa en MATLAB que lleve a cabo la función de reconocimiento facial, y evaluar el funcionamiento del sistema desarrollado. Este documento se encuentra dividido en cuatro partes: INTRODUCCIÓN, MARCO TEÓRICO, IMPLEMENTACIÓN, y RESULTADOS, CONCLUSIONES Y LÍNEAS FUTURAS. En la primera parte, se hace una introducción relativa a la actualidad del reconocimiento facial y se comenta brevemente sobre las técnicas existentes para desarrollar un sistema biométrico de este tipo. En ella se justifican también aquellas técnicas que acabaron formando parte de la implementación. En la segunda parte, el marco teórico, se explica la estructura general que tiene un sistema de reconocimiento biométrico, así como sus modos de funcionamiento, y las tasas de error utilizadas para evaluar y comparar su rendimiento. Así mismo, se lleva a cabo una descripción más profunda sobre los conceptos y métodos utilizados para efectuar la detección y reconocimiento facial en la tercera parte del proyecto. La tercera parte abarca una descripción detallada de la solución propuesta. En ella se explica el diseño, características y aplicación de la implementación; que trata de un programa elaborado en MATLAB con interfaz gráfica, y que utiliza cuatro sistemas de reconocimiento facial, basados cada uno en diferentes técnicas: Análisis por componentes principales, análisis lineal discriminante, wavelets de Gabor, y emparejamiento de grafos elásticos. El programa ofrece además la capacidad de crear y editar una propia base de datos con etiquetas, dándole aplicación directa sobre el tema que se trata. Se proponen además una serie de características con el objetivo de ampliar y mejorar las funcionalidades del programa diseñado. Dentro de dichas características destaca la propuesta de un modo de verificación híbrido aplicable a cualquier rama de la biometría y un programa de evaluación capaz de medir, graficar, y comparar las configuraciones de cada uno de los sistemas de reconocimiento implementados. Otra característica destacable es la herramienta programada para la creación de grafos personalizados y generación de modelos, aplicable a reconocimiento de objetos en general. En la cuarta y última parte, se presentan al principio los resultados obtenidos. En ellos se contemplan y analizan las comparaciones entre las distintas configuraciones de los sistemas de reconocimiento implementados para diferentes bases de datos (una de ellas formada con imágenes con condiciones de adquisición no controladas). También se miden las tasas de error del modo de verificación híbrido propuesto. Finalmente, se extraen conclusiones, y se proponen líneas futuras de investigación. ABSTRACT The main goal of this project is to develop a facial recognition system. To meet this end, it was necessary to accomplish a series of specific objectives, which were: researching on the existing face recognition technics nowadays, choosing an application where face recognition might be useful, design and develop a face recognition system using MATLAB, and measure the performance of the implemented system. This document is divided into four parts: INTRODUCTION, THEORTICAL FRAMEWORK, IMPLEMENTATION, and RESULTS, CONCLUSSIONS AND FUTURE RESEARCH STUDIES. In the first part, an introduction is made in relation to facial recognition nowadays, and the techniques used to develop a biometric system of this kind. Furthermore, the techniques chosen to be part of the implementation are justified. In the second part, the general structure and the two basic modes of a biometric system are explained. The error rates used to evaluate and compare the performance of a biometric system are explained as well. Moreover, a description of the concepts and methods used to detect and recognize faces in the third part is made. The design, characteristics, and applications of the systems put into practice are explained in the third part. The implementation consists in developing a program with graphical user interface made in MATLAB. This program uses four face recognition systems, each of them based on a different technique: Principal Component Analysis (PCA), Fisher’s Linear Discriminant (FLD), Gabor wavelets, and Elastic Graph Matching (EGM). In addition, with this implementation it is possible to create and edit one´s tagged database, giving it a direct application. Also, a group of characteristics are proposed to enhance the functionalities of the program designed. Among these characteristics, three of them should be emphasized in this summary: A proposal of an hybrid verification mode of a biometric system; and an evaluation program capable of measuring, plotting curves, and comparing different configurations of each implemented recognition system; and a tool programmed to create personalized graphs and models (tagged graph associated to an image of a person), which can be used generally in object recognition. In the fourth and last part of the project, the results of the comparisons between different configurations of the systems implemented are shown for three databases (One of them created with pictures taken under non-controlled environments). The error rates of the proposed hybrid verification mode are measured as well. Finally, conclusions are extracted and future research studies are proposed.

Este proyecto consiste en el diseño e implementación un sistema domótico que puede ser instalado en una vivienda para controlar distintas variables ambientales y conseguir así la máxima comodidad de los habitantes de manera automática o manual según los gustos y necesidades de los usuarios. La característica principal de este sistema, es que cuenta con un funcionamiento distribuido donde entran en juego un servidor, encargado de tomar las decisiones generales para el comportamiento de la casa, y una serie de controladores esclavo cuya función es mantener constantes las variables ambientales con los valores fijados por el servidor. Así se consigue mantener la vivienda en una situación de bienestar constante para cualquier persona que se encuentre dentro. El sistema ha sido pensado de manera que se intenta reducir al máximo el cableado para facilitar su instalación por lo que la comunicación entre los distintos dispositivos se hace de manera inalámbrica por medio de un protocolo descrito en la norma IEEE 802.15.4 llamado ZigBee. Para ello se ha utilizado un módulo de comunicación wireless llamado Xbee, el cual permite la comunicación entre dos dispositivos. Para el control de dicho sistema distribuido se cuenta con una aplicación web, que mediante una interfaz gráfica permite al usuario controlar los distintos dispositivos dentro de la vivienda consiguiendo así controlar las variables ambientales a gusto del usuario. Dicha interfaz gráfica no depende de un software específico, sino que sólo es necesario un cliente http como podría ser Internet Explorer, Mozilla Firefox, Google Chrome, etc. Para integrar dicho sistema se ha usado un mini ordenador de bajo coste llamado RaspBerryPi, en el que se encuentra alojado un servidor Apache con el fin de gestionar y automatizar las variables ambientales. El control de los dipositivos encargados de modificar y estabilizar las variables ambientales se realiza mediante unos controladores genéricos implementados mediante mcontroladores 80C51F410, pertenecientes a la familia 80C51, y una serie de componentes y circuitería que permiten el correcto funcionamiento de éstos. Existen dos tipos de controladores distintos, los cuales son: Controlador Sensor: Encargados de las tomas de valores ambientales como puede ser la luz y la temperatura. Controladores Actuadores: Encargados de actuar sobre los dispositivos que modifican y estabilizan las variables ambientales como pueden ser la calefacción, tiras de leds de iluminación, persianas, alarmas, etc. El conjunto de la RaspBerryPi y los diferentes controladores forman el prototipo diseñado para este proyecto fin de carrera, el cual puede ser ampliado sencillamente para abarcar una amplia gama de posibilidades y funcionalidades dentro de la comodidad de una vivienda. ABSTRACT. The project described in this report consisted designing and implementing a home automation system that could be installed in a house in order to control environmental variables and thus get the maximum comfort of the inhabitant automatically or manually according to their tastes and needs. The main feature of this system consists in a distributed system, formed by a server which is responsible for making the main decisions of the actions performed inside the house. In addition, there are a series of slave controlers whose function consists in keeping the environmental variables within the values established by the server. Thus gets to keep the home in a situation of constant wellbeing to anyone who is inside. The system has been designed in order to reduce the amount of wire needed for the inter-connection of the devices, by means of wireless communication. The devices chosen for the solution are Xbee modules, which use the Zigbee protocol in order to comunicate one between each other. The Zigbee protocol is fully described in the IEEE 802.15.4 standard. A web application has been used to control the distributed system. This application allows users to control various devices inside the house and subsequently the different environmental variables. This implementation allows obtaining the maximum comfort by means of a very simple graphical interface. In addition, the Graphical User Interface (GUI) does not depend on any specific software. This means that it would only be necessary a http client (such as Internet Explorer, Mozilla Firefox, Google Chrome, etc.) for handling the application. The system has been integrated using a low-cost mini computer called RaspBerryPi.This computer has an Apache server allocated which allows to manage and to automatize the different environmental variables. Furthermore, for changing and stabilizing those variables, some generic controllers have been developed, based on mcontrollers 80C51F410. There have been developed mainly two different types of controllers: Sensor Controllers, responsible for measuring the different environmental values, such as light and temperature; and Actuator Controllers, which purpose is to modify and stabilize those environmental variables by actuating on the heating, the led lamps, the blinders, the alarm, etc. The combination of the RaspBerryPi and the different controllers conform the prototype designed during this project. Additionally, this solution could be easily expanded in order to intake further functionalities adapted to new needs that could arise in the future.

El proyecto fin de carrera de herramienta de apoyo a la docencia en Sistemas Operativos quiere ayudar al alumno a entender el funcionamiento de un planificador a corto plazo. Lo hace mediante una representación gráfica de procesos que ocupan o el procesador o distintas unidades de entrada/salida mientras transcurre el tiempo. El tiempo está dividido en ciclos de reloj de un procesador, a lo que a continuación se referirá como unidades de tiempo. Los procesos están definidos por su nombre, la instante de entrada que entran al sistema, su prioridad y la secuencia de unidades de tiempo en el procesador y unidades de entrada/salida que necesitan para terminar su trabajo. El alumno puede configurar el sistema a su gusto en cuanto al número y comportamiento de las unidades de entrada/salida. Puede definir que una unidad solo permita acceso exclusivo a los procesos, es decir que solo un proceso puede ocuparla simultáneamente, o que permita el acceso múltiple a sus recursos. El alumno puede construir un planificador a corto plazo propio, integrarlo en el sistema y ver cómo se comporta. Se debe usar la interfaz Java proporcionada para su construcción. La aplicación muestra datos estadísticos como por ejemplo la eficiencia del sistema (el tiempo activo de la CPU dividido por el tiempo total de la simulación), tiempos de espera de los procesos, etc. Se calcula después de cada unidad de tiempo para que el alumno pueda ver el momento exacto donde la simulación tomó un giro inesperado. La aplicación está compuesta por un motor de simulación que contiene toda la lógica y un conjunto de clases que forman la interfaz gráfica que se presenta al usuario. Estos dos componentes pueden ser reemplazados siempre y cuando se mantenga la definición de sus conectores igual. La aplicación la he hecho de manejo muy simple e interfaz fácil de comprender para que el alumno pueda dedicar todo su tiempo a probar distintas configuraciones y situaciones y así entender mejor la asignatura. ABSTRACT. The project is called “Tool to Support Teaching of the Subject Operating Systems” and is an application that aims to help students understand on a deeper level the inner workings of how an operating system handles multiple processes in need of CPU time by the means of a short-term planning algorithm. It does so with a graphical representation of the processes that occupy the CPU and different input/output devices as time passes by. Time is divided in CPU cycles, from now on referred to as time units. The processes are defined by their name, the moment they enter the system, their priority and the sequence of time units they need to finish their job. The student can configure the system by changing the number and behavior of the input/output devices. He or she can define whether a device should only allow exclusive access, i.e. only one process can occupy it at any given time, or if it should allow multiple processes to access its resources. The student can build a planning algorithm of his or her own and easily integrate it into the system to see how it behaves. The provided Java interface and the programming language Java should be used to build it. The application shows statistical data, e.g. the efficiency of the system (active CPU time divided by total simulation time) and time spent by the processes waiting in queues. The data are calculated after passing each time unit in order for the student to see the exact moment where the simulation took an unexpected turn. The application is comprised of a simulation motor, which handles all the logic, and a set of classes, which is the graphical user interface. These two parts can be replaced individually if the definition of the connecting interfaces stays the same. I have made the application to be very easy to use and with an easy to understand user interface so the student can spend all of his or her time trying out different configurations and scenarios in order to understand the subject better.

Para estudiar la acústica en recintos se utilizan herramientas de modelado acústico de salas y la auralización de estos recintos. En muchos casos el mismo software de modelado genera las auralizaciones que simulan como se escucharía un determinado audio en un punto del recinto. En el presente trabajo se intenta estudiar la calidad de las respuestas impulsivas simuladas generadas por una de estas herramientas de modelado. El proyecto consiste en realizar una evaluación subjetiva de la diferenciación entre las respuestas impulsivas medidas y simuladas en diferentes recintos, comparándola con los parámetros acústicos objetivos que se han obtenido mediante una evaluación objetiva anterior. Para ello, se desarrolla una herramienta software que, con las respuestas impulsivas simuladas (generadas por un software de modelado acústico, ODEON) y las respuestas impulsivas medidas, genere: las auralizaciones correspondientes; un test de escucha para hacer la evaluación subjetiva de las auralizaciones obtenidas y una interfaz de usuario para interaccionar con los oyentes a evaluar; y que almacene los resultados del test de escucha. Además se llevará a cabo la evaluación subjetiva (test de escucha) con un grupo de oyentes, con los que posteriormente se obtendrán los resultados para poder comparar con los valores objetivos. A partir de los resultados del test de escucha, se estudiará la relación entre las diferencias de las respuestas impulsivas (medidas y simuladas) con respecto a: 1) parámetros objetivos (diferencias en valores de JND), 2) evaluación subjetiva (diferenciación subjetiva con el test de escucha) y, 3) comparación entre ambos. Finalmente, se obtendrán las conclusiones derivadas de este estudio. ABSTRACT. Tools of Room Acoustic Modeling and the auralization of these rooms have been used to study room Acoustics. In many cases, the modeling software itself generates the auralizations which simulate the sound of a particular audio in a particular position in a room. The quality of simulated impulse responses generated by a modelling tool has been studied in this project. The project carries out a subjective evaluation of the differences between measured and simulated impulse responses in different rooms, and in comparing them with objective acoustical parameters which have been obtained from the previous objective evaluation. For this, a software tool has been developed. This software, with simulated (generated by a modelling software, ODEON) and measured impulse responses generate: the correspondent auralizations, listening test (which carries out the subjective evaluation of the auralization) and a user interface to interact with listeners. This tool also stores the listening test results. In addition, the subjective evaluation (listening test) will be carried out with a group of listeners, from who we will get the results to compare subjective values. The differences between impulse responses (both measured and simulated) are obtained from the results of the listening test and these differences have been studied regarding: 1) objective parameters (difference in JND values); 2) subjetive evaluation (subjective differences with the listening test); 3) comparison between both. Eventually the conclussions derivative from this project will be obtained.

This paper presents a Focused Crawler in order to Get Semantic Web Resources (CSR). Structured data web are available in formats such as Extensible Markup Language (XML), Resource Description Framework (RDF) and Ontology Web Language (OWL) that can be used for processing. One of the main challenges for performing a manual search and download semantic web resources is that this task consumes a lot of time. Our research work propose a focused crawler which allow to download these resources automatically and store them on disk in order to have a collection that will be used for data processing. CRS consists of three layers: (a) The User Interface Layer, (b) The Focus Crawler Layer and (c) The Base Crawler Layer. CSR uses as a selection policie the Shark-Search method. CSR was conducted with two experiments. The first one starts on December 15 2012 at 7:11 am and ends on December 16 2012 at 4:01 were obtained 448,123,537 bytes of data. The CSR ends by itself after to analyze 80,4375 seeds with an unlimited depth. CSR got 16,576 semantic resources files where the 89 % was RDF, the 10 % was XML and the 1% was OWL. The second one was based on the Web Data Commons work of the Research Group Data and Web Science at the University of Mannheim and the Institute AIFB at the Karlsruhe Institute of Technology. This began at 4:46 am of June 2 2013 and 1:37 am June 9 2013. After 162.51 hours of execution the result was 285,279 semantic resources where predominated the XML resources with 99 % and OWL and RDF with 1 % each one.

The conception of IoT (Internet of Things) is accepted as the future tendency of Internet among academia and industry. It will enable people and things to be connected at anytime and anyplace, with anything and anyone. IoT has been proposed to be applied into many areas such as Healthcare, Transportation,Logistics, and Smart environment etc. However, this thesis emphasizes on the home healthcare area as it is the potential healthcare model to solve many problems such as the limited medical resources, the increasing demands for healthcare from elderly and chronic patients which the traditional model is not capable of. A remarkable change in IoT in semantic oriented vision is that vast sensors or devices are involved which could generate enormous data. Methods to manage the data including acquiring, interpreting, processing and storing data need to be implemented. Apart from this, other abilities that IoT is not capable of are concluded, namely, interoperation, context awareness and security & privacy. Context awareness is an emerging technology to manage and take advantage of context to enable any type of system to provide personalized services. The aim of this thesis is to explore ways to facilitate context awareness in IoT. In order to realize this objective, a preliminary research is carried out in this thesis. The most basic premise to realize context awareness is to collect, model, understand, reason and make use of context. A complete literature review for the existing context modelling and context reasoning techniques is conducted. The conclusion is that the ontology-based context modelling and ontology-based context reasoning are the most promising and efficient techniques to manage context. In order to fuse ontology into IoT, a specific ontology-based context awareness framework is proposed for IoT applications. In general, the framework is composed of eight components which are hardware, UI (User Interface), Context modelling, Context fusion, Context reasoning, Context repository, Security unit and Context dissemination. Moreover, on the basis of TOVE (Toronto Virtual Enterprise), a formal ontology developing methodology is proposed and illustrated which consists of four stages: Specification & Conceptualization, Competency Formulation, Implementation and Validation & Documentation. In addition, a home healthcare scenario is elaborated by listing its well-defined functionalities. Aiming at representing this specific scenario, the proposed ontology developing methodology is applied and the ontology-based model is developed in a free and open-source ontology editor called Protégé. Finally, the accuracy and completeness of the proposed ontology are validated to show that this proposed ontology is able to accurately represent the scenario of interest.

Este Proyecto Fin de Grado (PFG) tiene como objetivo diseñar e implementar un sistema que genere un fichero de texto que contenga la configuración básica de un encaminador. De esta manera se desea mejorar la eficiencia del personal del departamento donde se va a implantar dicho sistema, liberando a los miembros del mismo de un trabajo repetitivo que se hace varias veces al día. Hasta ahora, esta configuración la realiza cada instalador. Para ello, una vez que se ha cargado y probado la configuración en distintos equipos de manera satisfactoria, se generan un conjunto de plantillas que sirven de modelo para las siguientes configuraciones. Aunque el instalador toma estas plantillas como punto de partida, tiene que modificar manualmente todas las variables que dependen de cada configuración particular. Por tanto, aunque no ha de ejecutar todos los comandos paso a paso, sí debe hacer una revisión total de cada plantilla para generar la configuración adecuada y después cargarla en el encaminador. Para cada configuración se consultan un total de entre tres y siete plantillas. Si a esto se añade que en el departamento se configuran encaminadores de la marca Cisco y Teldat, que de cada marca se utilizan distintos modelos y que la empresa ofrece cuatro tipos de servicio, cada uno con sus particularidades, la tarea de configurar un equipo es costosa. El sistema estará constituido por un servidor web que alojará una base de datos y un programa que permite realizar operaciones de consulta sobre la misma, un sitio web sencillo que hará las funciones de interfaz de usuario y una aplicación que permite generar el fichero de texto que contiene la configuración del encaminador en base a una serie de condicionantes. La base de datos desarrollada es una representación de la utilizada en el entorno real que tiene como objetivo realizar simulaciones del funcionamiento que tendrá el sistema. Por su parte, la funcionalidad del sitio web debe ser la de ofrecer al usuario una interfaz sencilla de utilizar y de interpretar, a través de la cual se puedan realizar consultas a la base de datos así como presentar los resultados de dichas consultas de forma ordenada. La aplicación se encargará de validar los datos a partir de los que se va a generar la configuración, determinar qué plantillas se deben consultar en función a aspectos como el servicio a configurar o la marca del encaminador y finalmente generar el fichero de texto resultado. De este modo, el instalador simplemente tendrá que volcar la información de dicho fichero sobre el encaminador. El sistema se ha diseñado de manera que sea lo más flexible a cambios, puesto que la idea de los miembros del departamento es ampliar la funcionalidad de esta herramienta. ABSTRACT. This Final Degree Project is focused on the design and implementation of a system which is able to generate a text file that contains the basic configuration of a router. With this system we want to improve the efficiency of the department members where this system is going to be introduced, releasing them from repetitive work which is done several times per day. Up to now, each installer has to configure the router manually. After checking the configuration of several devices successfully, they create a set of templates which work as models. Although the installers use those templates, they have to modify the variables that depend on the specific features of each kind of configuration. Thus, even though they don´t have to execute the commands step by step, they have to do a review of each used template in order to generate the right configuration. For each configuration, three to seven templates have to be checked. In addition, if the configured routers are both Cisco and Teldat, there are several models per brand and the company offers four types of services to be installed, so the configuration becomes a hard task to do. The system is comprised of a web server in which both the database and the program responsible for doing queries are hosted, a simple web site that will be the graphic user interface, and an application focused on generating the text file which contains the router configuration based on a set of conditions. The developed database is the representation of the real one and its aim is to simulate the way the system will work. The function of the web site is to offer an easy interface whereby you can submit a query or you can see the obtained results as a data table. Furthermore, the application has to validate the data in which the text file with the router configuration is based on. Then, it has to decide which templates it is going to use according to different aspects, such as the brand of the router or the type of service we want to configure. Finally, the application generates a text file with the necessary commands. As a result of this, the user of the system only has to copy the contents of this file to the router. The system has been designed to be flexible to changes because the members of the department want to increase the utility of this tool in the future.
