Análisis de datos y modelado simbólico para aplicación de detección temprana de trastornos del lenguaje

Este Proyecto Fin de Grado trabaja en pos de la mejora y ampliación de los sistemas Pegaso y Gades, dos Sistemas Expertos enmarcados en el ámbito de la e-Salud. Estos sistemas, que ya estaban en funcionamiento antes del comienzo de este trabajo, apoyan la toma de decisiones en Atención Primaria. Esto es, permiten evaluar el nivel de adquisición del lenguaje en niños de 0 a 6 años a través de sus respectivas aplicaciones web. Además, permiten almacenar dichas evaluaciones y consultarlas posteriormente, junto con las decisiones del sistema asociadas a las mismas. Pegaso y Gades siguen una arquitectura de tres capas y están desarrollados usando fundamentalmente componentes Java y siguiendo. Como parte de este trabajo, en primer lugar se solucionan algunos problemas en el comportamiento de ambos sistemas, como su incompatibilidad con Java SE 7. A continuación, se desarrolla una aplicación que permite generar una ontología en lenguaje OWL desde código Java. Para ello, se estudia primero el concepto de ontología, el lenguaje OWL y las diferentes librerías Java existentes para generar ontologías OWL. Por otra parte, se mejoran algunas de las funcionalidades de los sistemas de partida y se desarrolla una nueva funcionalidad para la explotación de los datos almacenados en las bases de datos de ambos sistemas Esta nueva funcionalidad consiste en un módulo responsable de la generación de estadísticas a partir de los datos de las evaluaciones del lenguaje que hayan sido realizadas y, por tanto, almacenadas en las bases de datos. Estas estadísticas, que pueden ser consultadas por todos los usuarios de Pegaso y Gades, permiten establecer correlaciones entre los diversos conjuntos de datos de las evaluaciones del lenguaje. Por último, las estadísticas son mostradas por pantalla en forma de varios tipos de gráficas y tablas, de modo que los usuarios expertos puedan analizar la información contenida en ellas. ABSTRACT. This Bachelor's Thesis works towards improving and expanding the systems Pegaso and Gades, which are two Expert Systems that belong to the e-Health field. These systems, which were already operational before starting this work, support the decision-making process in Primary Care. That is, they allow to evaluate the language acquisition level in children from 0 to 6 years old. They also allow to store these evaluations and consult them afterwards, together with the decisions associated to each of them. Pegaso and Gades follow a three-tier architecture and are developed using mainly Java components. As part of this work, some of the behavioural problems of both systems are fixed, such as their incompatibility with Java SE 7. Next, an application that allows to generate an OWL ontology from Java code is developed. In order to do that, the concept of ontology, the OWL language and the different existing Java libraries to generate OWL ontologies are studied. On the other hand, some of the functionalities of the initial systems are improved and a new functionality to utilise the data stored in the databases of both systems is developed. This new functionality consists of a module responsible for the generation of statistics from the data of the language evaluations that have been performed and, thus, stored in the databases. These statistics, which can be consulted by all users of Pegaso and Gades, allow to establish correlations between the diverse set of data from the language evaluations. Finally, the statistics are presented to the user on the screen in the shape of various types of charts and tables, so that the expert users can analyse the information contained in them.

Cálculo de la atracción gravimétrica inducida por el Pabellón de Gravimetría del Centro de Desarrollos Tecnológicos de Yebes (Instituto Geográfico Nacional).

En el presente Trabajo Fin de Grado se modeliza la estructura del Pabellón de Gravimetría del Centro Astronómico de Yebes para así poder determinar su influencia sobre los valores de gravedad observados en el interior del Pabellón. El Pabellón de Gravimetría dispone en su interior de una sala dónde se realizan medidas de gravedad sobre siete pilares de hormigón situados a nivel del suelo. Para poder modelizar la sala de medida se ha realizado un levantamiento topográfico con las especificaciones técnicas de una escala 1:100. Tras la realización del levantamiento se han determinado las coordenadas geográficas del centro de los pilares de medida mediante el cálculo de una radiación, pues es necesario conocer éste dato al realizar medidas relativas de gravedad. Para el cálculo de la influencia que genera la estructura del Pabellón sobre las medidas de gravedad observadas en su interior se han creado una serie de programas en lenguaje Java empleando la fórmula de la atracción gravitatoria que genera un prisma (Nagy, 1969). Una vez se han llevado a cabo las observaciones y los cálculos necesarios se concluye que la influencia de la estructura sobre las medidas de la gravedad observadas en el interior del Pabellón no es de gran magnitud. No obstante esnecesario conocerla y así poder corregir los valores observados. Asimismo, se determina cierta desorientación de los pilares de medida con respecto al norte geográfico. El presente Trabajo Fin de Grado permitirá, entre otros, que el Centro de Desarrollos Tecnológicos de Yebes participe en proyectos de carácter internacional. Abstract: In the current Bachelor Thesis, the structure of the Pavellón de Gravimetría del Centro Astronómico de Yebes is moulded in order to determine its influence on the observed values of gravity inside the Pavilion. The Pabellón de Gravimetría holds in its interior a room where gravity measures are made on seven concrete pillars located on the ground level. In order to be able to mould the room, a topographical survey measurement was made on a 1:100 scale. After concluding the topographical survey measurement the geographical coordinates of the centre of the measurement pillars were determined, due to the necessity to know this data when making relative gravity measures. To calculate the influence that the pavilion structure has on the observed gravity measures in its interior generates, a series of programs in Java language have been created using the formula of the gravitational attraction that generates a prism (Nagy, 1969). Once the observations and the necessary calculations have been carried out, it is concluded that the influences of the structure of the Pavilion on the observed gravity measures inside it are not of a considerable magnitude. Despite that, it is necessary to know this to be able to correct the observed values. Also, certain disorientations of the pillars of measurement with respect to the geographical north is determined. The current Bachelor Thesis will allow, among others, the Centre of Technological Developments of Yebes to get involved in projects of international nature.

The development of a wind tunnel DAQ system by using Labview tools

This paper presents the experimental three-year learning activity developed by a group of teachers in a wind tunnel facility. The authors, leading a team of students, carried out a project consisting of the design, assembly and testing of a wind tunnel. The project included all stages of the process from its initial specifications to its final quality flow assessments, going through the calculation of each element, and the building of the whole wind tunnel. The group of (final year) students was responsible for the whole wind tunnel project as a part of their bachelor degree project. The paper focuses on the development of wind tunnel data acquisition software. This automatic tool is essential to improve the automation of the data acquisition of the wind tunnel facility systems, in particular for a 6DOF multi-axis force/torque sensor. This work can be considered as a typical example of real engineering practice: a set of specifications that has to be modified due to the constraints imposed throughout the project, in order to obtain the final result

Student academic performance stochastic simulator based on the Monte Carlo method

In this paper, a computer-based tool is developed to analyze student performance along a given curriculum. The proposed software makes use of historical data to compute passing/failing probabilities and simulates future student academic performance based on stochastic programming methods (MonteCarlo) according to the specific university regulations. This allows to compute the academic performance rates for the specific subjects of the curriculum for each semester, as well as the overall rates (the set of subjects in the semester), which are the efficiency rate and the success rate. Additionally, we compute the rates for the Bachelors degree, which are the graduation rate measured as the percentage of students who finish as scheduled or taking an extra year and the efficiency rate (measured as the percentage of credits of the curriculum with respect to the credits really taken). In Spain, these metrics have been defined by the National Quality Evaluation and Accreditation Agency (ANECA). Moreover, the sensitivity of the performance metrics to some of the parameters of the simulator is analyzed using statistical tools (Design of Experiments). The simulator has been adapted to the curriculum characteristics of the Bachelor in Engineering Technologies at the Technical University of Madrid(UPM).

PCCMuTe v2.2: una herramienta para medir el consumo de energía en sistemas empotrados

Este Proyecto Fin de Grado (PFG) recoge el trabajo de depuración realizado sobre el prototipo PCCMuTe v2.2, un sistema empotrado que dispone de la instrumentación necesaria para medir el consumo de potencia/energía en cada uno de sus dominios de tensión, y posteriormente digitalizar y enviar los resultados al procesador que se encuentra en su interior. Su uso permite la obtención de información en tiempo real sobre el consumo del hardware de la placa, en especial del procesador, pudiendo relacionar la potencia consumida con el software ejecutado. El proyecto está orientado a medir el consumo de energía derivado de la decodificación de vídeo. El software utilizado para controlar el hardware se basa en Linux. En este proyecto se distinguen principalmente dos actividades, depuración hardware y depuración software. Los resultados muestran avances en la depuración hardware hasta obtener un prototipo en completo funcionamiento. Los avances en el apartado del software habilitan las comunicaciones SPI, necesarias para la transmisión de los resultados de consumo al procesador. En la fase final de este PFG se hace uso de una aplicación previamente desarrollada por miembros del GDEM con la que se obtienen los primeros datos de consumo, pero por falta de tiempo estos resultados no pueden ser verificados. Por la misma razón no ha sido posible diseñar y codificar una nueva aplicación que mejore la forma en la que se obtienen esos datos. ABSTRACT. This bachelor final project includes the debugging work done on the prototype PCCMuTe v2.2, an embedded system with the necessary instrumentation to measure the power/ energy consumption in each of its voltage domains, scan and send the results to its processor. The purpose of this device is to obtain real-time information about the hardware power consumption, especially from the processor, being able to relate the power consumed with the software executed. The project aims to measure the energy consumption of video decoding. The software used to control the hardware is based on Linux. In this project there are two main activities: hardware and software debugging. The results show advances in hardware debugging, and finally a fully functioning prototype is obtained. Advances in software debugging enable SPI communications, used to transmit the consumption data to the processor. In the last part of this final bachelor project an application previously coded by other members of the GDEM is used to obtain the first data. The results can not finally be verified because of the lack of time. For the same reason it is not possible to design and code a new application that improves the way the data is obtained.

Los contenidos de expresión corporal en el titulo de grado en ciencias del deporte

La Expresión Corporal como materia educativa tiene su origen en España, de forma ligada a la Educación Física y su desarrollo en el ámbito universitario, durante la segunda mitad del siglo XX. Pero su corpus teórico no se encuentra definitivamente asentado, dando lugar a diferentes interpretaciones y consideraciones sobre cuáles deben ser considerados contenidos propios de la materia y sobre cómo deben ser estructurados. La presente tesis tiene por objeto de estudio precisamente los contenidos de la Expresión Corporal como materia perteneciente a las Ciencias de la Actividad Física y del Deporte, tratando de dar una respuesta fundamentada al planteamiento anterior. Para lo cual se seleccionaron y analizaron las principales obras de referencia para la materia en base a las cuales establecer una estructura de bloques de contenido y categorías asociadas. Se analizó la oferta formativa que, desde las universidades públicas españolas, se realizaba sobre el título de licenciado en Ciencias de la Actividad Física y del Deporte, comprobando por una parte la heterogeneidad en el tratamiento dado y por otra su adecuación a la estructura generada. Y en tercer lugar se examinó la normativa que articula y desarrolla el tratamiento de la Expresión Corporal en la Ley Orgánica de Educación, concretando el análisis en la etapa de Secundaria, en un proceso de triangulación sobre las fuentes documentales de mayor influencia, constatando una aparente falta de estructura en la selección y planteamiento de los contenidos a desarrollar dentro de la asignatura de Educación Física. En base a estas investigaciones, a la propia experiencia docente del doctorando y a la contribución de diferentes expertos en la materia se desarrolla una propuesta estructurada de contenidos de Expresión Corporal, la cual es implementada en el título de grado en Ciencias de la Actividad Física y del Deporte ofertado por la Universidad Politécnica de Madrid, analizando finalmente el nivel de relevancia que perciben los alumnos respecto de los contenidos de la materia planteados, infiriendo de los resultados obtenidos que se produce un aprendizaje significativo por parte de los futuros titulados. Se organizó la investigación en torno a cinco fases, utilizando en las tres primeras como metodología principal en análisis de contenido de las principales fuentes documentales (obras de referencia, programas docentes universitarios y normativa educativa), la cual es apoyada por otras herramientas como el grupo de discusión. La cuarta fase consistente en la elaboración de una propuesta estructurada de contenidos, contó con la valoración de un grupo de expertos en la materia. Mientras que en la fase de implementación y evaluación se recurrió al formato de entrevista colectiva mediante el empleo de cuestionario auto cumplimentado. La principal contribución de este trabajo es por tanto la presentación de una propuesta de estructuración de contenidos en Expresión Corporal, como parte de las manifestaciones básicas de la motricidad humana y enmarcada en el ámbito de las Ciencias de la Actividad Física y del Deporte; que tiene respaldo en las obras de referencia de la materia, en la formación inicial de los licenciados en Ciencias de la Actividad Física y del Deporte y en el desarrollo normativo de la Ley Orgánica de Educación; y que ha sido implementada en el actual título de Grado en Ciencias de la Actividad Física y del Deporte de la Universidad Politécnica de Madrid con resultados satisfactorios. ABSTRACT Corporal Expression as an educational subject has it origin s in Spain, linked to physical education and its development at University context, during the second half of the twentieth century. But his academic corpus has not been definitively settled, leading to different interpretations and considerations about what should be considered as proper contents of subject and how they should be structured. This thesis aims to study precisely the contents of the Corporal Expression as a subject belonging to Sciences of Physical Activity and Sport, trying to give a reasoned response to the previous approach. Taking this objective into consideration, main reference works were selected and analyzed to set a content structure and associated categories. The training offer of Spanish public universities in the Science of Physical Activity and Sport degree was analyzed, checking on the one hand the heterogeneity in the treatment and on the other their suitability to the structure generated. Thirdly, normative related to the treatment of Corporal Expression in the Ley Orgánica de Educación was examined paying special attention to the Secondary School stage. The process of triangulation which was performed using the most influential documentary sources suggested an apparent lack of structure and approach in the selection of contents to be developed in the subject of Physical Education. Based on these investigations, on the own teaching experience of the candidate and on the contribution of various experts in the field, a structured proposal of Corporal Expression contents is offered. This proposal has been implemented in the bachelor's degree in Sports Science offered by the Technical University of Madrid. Level of importance of the implemented contents perceived by students was analyzed and results suggested the presence of meaningful learning among graduates. Research was split into five phases. In the first three phases content analysis of the main documentary sources (reference books, university programs and educational standards), which was supported by other tools like the discussion group was the principal methodology. The fourth phase consisted in the development of a proposal structured content, involving the assessment of a group of experts in the field. In the implementation and evaluation phase collective interview using self-completed questionnaire was conducted The main contribution of this work is therefore presenting a proposal for structuring content in Corporal Expression, as a part of the basic manifestations of human motorskill and framed in the field of Sciences of Physical Activity and Sport; which draws on the support of reference works, initial training of graduates in Science of Physical Activity and Sport and the development of the normative of the Ley Orgánica de Educación; and has been implemented in the current Degree in Sports Science of the Technical University of Madrid with satisfactory results.

VHDL-based system design of a cognitive sensorimotor loop (CSL) for haptic Human-Machine Interaction (HMI)

This document is a summary of the Bachelor thesis titled “VHDL-Based System Design of a Cognitive Sensorimotor Loop (CSL) for Haptic Human-Machine Interaction (HMI)” written by Pablo de Miguel Morales, Electronics Engineering student at the Universidad Politécnica de Madrid (UPM Madrid, Spain) during an Erasmus+ Exchange Program at the Beuth Hochschule für Technik (BHT Berlin, Germany). The tutor of this project is Dr. Prof. Hild. This project has been developed inside the Neurobotics Research Laboratory (NRL) in close collaboration with Benjamin Panreck, a member of the NRL, and another exchange student from the UPM Pablo Gabriel Lezcano. For a deeper comprehension of the content of the thesis, a deeper look in the document is needed as well as the viewing of the videos and the VHDL design. In the growing field of automation, a large amount of workforce is dedicated to improve, adapt and design motor controllers for a wide variety of applications. In the specific field of robotics or other machinery designed to interact with humans or their environment, new needs and technological solutions are often being discovered due to the existing, relatively unexplored new scenario it is. The project consisted of three main parts: Two VHDL-based systems and one short experiment on the haptic perception. Both VHDL systems are based on a Cognitive Sensorimotor Loop (CSL) which is a control loop designed by the NRL and mainly developed by Dr. Prof. Hild. The CSL is a control loop whose main characteristic is the fact that it does not use any external sensor to measure the speed or position of the motor but the motor itself. The motor always generates a voltage that is proportional to its angular speed so it does not need calibration. This method is energy efficient and simplifies control loops in complex systems. The first system, named CSL Stay In Touch (SIT), consists in a one DC motor system controller by a FPGA Board (Zynq ZYBO 7000) whose aim is to keep contact with any external object that touches its Sensing Platform in both directions. Apart from the main behavior, three features (Search Mode, Inertia Mode and Return Mode) have been designed to enhance the haptic interaction experience. Additionally, a VGA-Screen is also controlled by the FPGA Board for the monitoring of the whole system. This system has been completely developed, tested and improved; analyzing its timing and consumption properties. The second system, named CSL Fingerlike Mechanism (FM), consists in a fingerlike mechanical system controlled by two DC motors (Each controlling one part of the finger). The behavior is similar to the first system but in a more complex structure. This system was optional and not part of the original objectives of the thesis and it could not be properly finished and tested due to the lack of time. The haptic perception experiment was an experiment conducted to have an insight into the complexity of human haptic perception in order to implement this knowledge into technological applications. The experiment consisted in testing the capability of the subjects to recognize different objects and shapes while being blindfolded and with their ears covered. Two groups were done, one had full haptic perception while the other had to explore the environment with a plastic piece attached to their finger to create a haptic handicap. The conclusion of the thesis was that a haptic system based only on a CSL-based system is not enough to retrieve valuable information from the environment and that other sensors are needed (temperature, pressure, etc.) but that a CSL-based system is very useful to control the force applied by the system to interact with haptic sensible surfaces such as skin or tactile screens. RESUMEN. Este documento es un resumen del proyecto fin de grado titulado “VHDL-Based System Design of a Cognitive Sensorimotor Loop (CSL) for Haptic Human-Machine Interaction (HMI)” escrito por Pablo de Miguel, estudiante de Ingeniería Electrónica de Comunicaciones en la Universidad Politécnica de Madrid (UPM Madrid, España) durante un programa de intercambio Erasmus+ en la Beuth Hochschule für Technik (BHT Berlin, Alemania). El tutor de este proyecto ha sido Dr. Prof. Hild. Este proyecto se ha desarrollado dentro del Neurorobotics Research Laboratory (NRL) en estrecha colaboración con Benjamin Panreck (un miembro del NRL) y con Pablo Lezcano (Otro estudiante de intercambio de la UPM). Para una comprensión completa del trabajo es necesaria una lectura detenida de todo el documento y el visionado de los videos y análisis del diseño VHDL incluidos en el CD adjunto. En el creciente sector de la automatización, una gran cantidad de esfuerzo está dedicada a mejorar, adaptar y diseñar controladores de motor para un gran rango de aplicaciones. En el campo específico de la robótica u otra maquinaria diseñada para interactuar con los humanos o con su entorno, nuevas necesidades y soluciones tecnológicas se siguen desarrollado debido al relativamente inexplorado y nuevo escenario que supone. El proyecto consta de tres partes principales: Dos sistemas basados en VHDL y un pequeño experimento sobre la percepción háptica. Ambos sistemas VHDL están basados en el Cognitive Sesnorimotor Loop (CSL) que es un lazo de control creado por el NRL y cuyo desarrollador principal ha sido Dr. Prof. Hild. El CSL es un lazo de control cuya principal característica es la ausencia de sensores externos para medir la velocidad o la posición del motor, usando el propio motor como sensor. El motor siempre genera un voltaje proporcional a su velocidad angular de modo que no es necesaria calibración. Este método es eficiente en términos energéticos y simplifica los lazos de control en sistemas complejos. El primer sistema, llamado CSL Stay In Touch (SIT), consiste en un sistema formado por un motor DC controlado por una FPGA Board (Zynq ZYBO 7000) cuyo objetivo es mantener contacto con cualquier objeto externo que toque su plataforma sensible en ambas direcciones. Aparte del funcionamiento básico, tres modos (Search Mode, Inertia Mode y Return Mode) han sido diseñados para mejorar la interacción. Adicionalmente, se ha diseñado el control a través de la FPGA Board de una pantalla VGA para la monitorización de todo el sistema. El sistema ha sido totalmente desarrollado, testeado y mejorado; analizando su propiedades de timing y consumo energético. El segundo sistema, llamado CSL Fingerlike Mechanism (FM), consiste en un mecanismo similar a un dedo controlado por dos motores DC (Cada uno controlando una falange). Su comportamiento es similar al del primer sistema pero con una estructura más compleja. Este sistema no formaba parte de los objetivos iniciales del proyecto y por lo tanto era opcional. No pudo ser plenamente desarrollado debido a la falta de tiempo. El experimento de percepción háptica fue diseñado para profundizar en la percepción háptica humana con el objetivo de aplicar este conocimiento en aplicaciones tecnológicas. El experimento consistía en testear la capacidad de los sujetos para reconocer diferentes objetos, formas y texturas en condiciones de privación del sentido del oído y la vista. Se crearon dos grupos, en uno los sujetos tenían plena percepción háptica mientras que en el otro debían interactuar con los objetos a través de una pieza de plástico para generar un hándicap háptico. La conclusión del proyecto fue que un sistema háptico basado solo en sistemas CSL no es suficiente para recopilar información valiosa del entorno y que debe hacer uso de otros sensores (temperatura, presión, etc.). En cambio, un sistema basado en CSL es idóneo para el control de la fuerza aplicada por el sistema durante la interacción con superficies hápticas sensibles tales como la piel o pantallas táctiles.

Desarrollo de ontología de títulos de grado

Dada la amplia información que rodea el dominio de programas de estudios superiores, específicamente los estudios de grado, este trabajo fin de grado propone la construcción de un modelo para representar dicha información mediante la construcción de una red de ontologías, proporcionando una definición común de conceptos importantes, y que posteriormente puede ser reutilizada para la construcción de aplicaciones que ayuden a las partes interesadas, como, estudiantes, personal académico y administrativo, a la búsqueda y acceso de información oportuna. Para la construcción de esta red de ontologías, se siguen las recomendaciones y pautas propuestas por la metodología NeOn [1a] [1b], que sigue un paradigma basado en la reutilización de recursos de conocimiento. Por otra parte, se realiza una populación de dicha red de ontologías mediante datos específicos del grado en Ingeniería Informática de la Universidad Politécnica de Madrid. La construcción de una red de ontologías siguiendo las directrices de la metodología NeOn requiere la realización de distintas actividades y tareas, como el estudio del dominio, estudio de la viabilidad, especificación de requisitos, conceptualización, formalización, implementación y mantenimiento. Se realizan también muchas otras actividades y tareas dependiendo del contexto en el que se construye la ontología. En este proyecto se hace un especial énfasis en las actividades de especificación de requisitos, conceptualización e implementación, además de la actividad de búsqueda de recursos ontológicos para su posterior reutilización. Se ha construido una red de ontologías llamada: European Bachelor Degree Ontology (EBDO) que incluye términos y conceptos importantes que se han detectado en la etapa de especificación de requisitos y que las ontologías a reutilizar no contemplan. Las decisiones de diseño para la construcción de esta nueva red de ontologías y su alineamiento con las ontologías a reutilizar se han basado en la especificación de requisitos ontológicos. Una vez definidos los conceptos relevantes de la red de ontologías, se ha implementado la red de ontologías en un lenguaje computable. Una vez que la red de ontologías se ha implementado se han realizado tareas de evaluación para corregir posible errores. Finalmente, cuando se ha obtenido una versión estable de la ontología, se ha realizado la instanciación de individuos del plan de estudios del grado en Ingeniería Informática de la Universidad Politécnica de Madrid.---ABSTRACT---Given the extensive information surrounding the domain of higher education programs, specifically bachelor degree studies, this bachelor degree project proposes the construction of a model to represent this information by building an ontology network, providing a common definition of important concepts. This network can be reused to build semantic applications that help stakeholders, such as, students, academic and organisational staff, to search and access to timely information. For the construction of this network of ontologies, guidelines and recommendations proposed by the NeOn Methodology [1a] [1b] have been followed. This methodology follows a paradigm based on the reuse of knowledge resources. Moreover, a population of this ontology network is performed with specific data of the Computer Science Degree from Universidad Politécnica de Madrid Building a network of ontologies following the guidelines of the NeOn Methodology requires the completion of various activities and tasks such as, the study of the domain, study of the feasibility, requirements specification, conceptualization, formalization, implementation and maintenance. Many other activities and tasks are also performed depending on the context in which the ontology is built. In this project a special emphasis is made on the activities of requirements specification, conceptualization and search of ontological resources for reuse and implementation. A new network of ontologies, named European Bachelor Degree Ontology (EBDO), has been built. This network includes terms and concepts that have been detected at the stage of requirements specification and that the reused ontologies have not contemplated. Design principles for the construction of this new network of ontologies and for the reused ontologies alignment have been based on the ontological specification requirements. Once the relevant concepts of the ontology network are defined, the network has been implemented in a computable ontology language. Once the network ontology is implemented, the evaluation activity has been conducted to correct the errors that the network presented. Finally, when a stable version of the ontology has been obtained, the instantiation of individuals of the study program of the Bachelor Degree in Computer Science from Universidad Politécnica de Madrid has been performed.

Development of a sensorimotor algorithm able to deal with unforeseen pushes and its implementation based on VHDL

Development of a Sensorimotor Algorithm Able to Deal with Unforeseen Pushes and Its Implementation Based on VHDL is the title of my thesis which concludes my Bachelor Degree in the Escuela Técnica Superior de Ingeniería y Sistemas de Telecomunicación of the Universidad Politécnica de Madrid. It encloses the overall work I did in the Neurorobotics Research Laboratory from the Beuth Hochschule für Technik Berlin during my ERASMUS year in 2015. This thesis is focused on the field of robotics, specifically an electronic circuit called Cognitive Sensorimotor Loop (CSL) and its control algorithm based on VHDL hardware description language. The reason that makes the CSL special resides in its ability to operate a motor both as a sensor and an actuator. This way, it is possible to achieve a balanced position in any of the robot joints (e.g. the robot manages to stand) without needing any conventional sensor. In other words, the back electromotive force (EMF) induced by the motor coils is measured and the control algorithm responds depending on its magnitude. The CSL circuit contains mainly an analog-to-digital converter (ADC) and a driver. The ADC consists on a delta-sigma modulation which generates a series of bits with a certain percentage of 1's and 0's, proportional to the back EMF. The control algorithm, running in a FPGA, processes the bit frame and outputs a signal for the driver. This driver, which has an H bridge topology, gives the motor the ability to rotate in both directions while it's supplied with the power needed. The objective of this thesis is to document the experiments and overall work done on push ignoring contractive sensorimotor algorithms, meaning sensorimotor algorithms that ignore large magnitude forces (compared to gravity) applied in a short time interval on a pendulum system. This main objective is divided in two sub-objectives: (1) developing a system based on parameterized thresholds and (2) developing a system based on a push bypassing filter. System (1) contains a module that outputs a signal which blocks the main Sensorimotor algorithm when a push is detected. This module has several different parameters as inputs e.g. the back EMF increment to consider a force as a push or the time interval between samples. System (2) consists on a low-pass Infinite Impulse Response digital filter. It cuts any frequency considered faster than a certain push oscillation. This filter required an intensive study on how to implement some functions and data types (fixed or floating point data) not supported by standard VHDL packages. Once this was achieved, the next challenge was to simplify the solution as much as possible, without using non-official user made packages. Both systems behaved with a series of interesting advantages and disadvantages for the elaboration of the document. Stability, reaction time, simplicity or computational load are one of the many factors to be studied in the designed systems. RESUMEN. Development of a Sensorimotor Algorithm Able to Deal with Unforeseen Pushes and Its Implementation Based on VHDL es un Proyecto de Fin de Grado (PFG) que concluye mis estudios en la Escuela Técnica Superior de Ingeniería y Sistemas de Telecomunicación de la Universidad Politécnica de Madrid. En él se documenta el trabajo de investigación que realicé en el Neurorobotics Research Laboratory de la Beuth Hochschule für Technik Berlin durante el año 2015 mediante el programa de intercambio ERASMUS. Este PFG se centra en el campo de la robótica y en concreto en un circuito electrónico llamado Cognitive Sensorimotor Loop (CSL) y su algoritmo de control basado en lenguaje de modelado hardware VHDL. La particularidad del CSL reside en que se consigue que un motor haga las veces tanto de sensor como de actuador. De esta manera es posible que las articulaciones de un robot alcancen una posición de equilibrio (p.ej. el robot se coloca erguido) sin la necesidad de sensores en el sentido estricto de la palabra. Es decir, se mide la propia fuerza electromotriz (FEM) inducida sobre el motor y el algoritmo responde de acuerdo a su magnitud. El circuito CSL se compone de un convertidor analógico-digital (ADC) y un driver. El ADC consiste en un modulador sigma-delta, que genera una serie de bits con un porcentaje de 1's y 0's determinado, en proporción a la magnitud de la FEM inducida. El algoritmo de control, que se ejecuta en una FPGA, procesa esta cadena de bits y genera una señal para el driver. El driver, que posee una topología en puente H, provee al motor de la potencia necesaria y le otorga la capacidad de rotar en cualquiera de las dos direcciones. El objetivo de este PFG es documentar los experimentos y en general el trabajo realizado en algoritmos Sensorimotor que puedan ignorar fuerzas de gran magnitud (en comparación con la gravedad) y aplicadas en una corta ventana de tiempo. En otras palabras, ignorar empujones conservando el comportamiento original frente a la gravedad. Para ello se han desarrollado dos sistemas: uno basado en umbrales parametrizados (1) y otro basado en un filtro de corte ajustable (2). El sistema (1) contiene un módulo que, en el caso de detectar un empujón, genera una señal que bloquea el algoritmo Sensorimotor. Este módulo recibe diferentes parámetros como el incremento necesario de la FEM para que se considere un empujón o la ventana de tiempo para que se considere la existencia de un empujón. El sistema (2) consiste en un filtro digital paso-bajo de respuesta infinita que corta cualquier variación que considere un empujón. Para crear este filtro se requirió un estudio sobre como implementar ciertas funciones y tipos de datos (coma fija o flotante) no soportados por las librerías básicas de VHDL. Tras esto, el objetivo fue simplificar al máximo la solución del problema, sin utilizar paquetes de librerías añadidos. En ambos sistemas aparecen una serie de ventajas e inconvenientes de interés para el documento. La estabilidad, el tiempo de reacción, la simplicidad o la carga computacional son algunas de las muchos factores a estudiar en los sistemas diseñados. Para concluir, también han sido documentadas algunas incorporaciones a los sistemas: una interfaz visual en VGA, un módulo que compensa el offset del ADC o la implementación de una batería de faders MIDI entre otras.

SONIA REGINA PRADO

A dissertação teve como objetivo principal estudar como uma Instituição de Ensino Superior Privada (IES) atuante no Brasil tem crescido pós Lei de Diretrizes e Bases (LDB) de 1996 até 2015, por meio da análise do curso de bacharelado em Administração de Empresas, nas modalidades: presencial, EAD e Flex (semipresencial). Para este fim, foi realizada uma pesquisa exploratória, de caráter qualitativo baseada no método do estudo de caso. Para coleta de evidências foram analisados relatórios corporativos (Annual Report, Relatórios Internos e outros documentos), entrevistas baseadas em roteiro semiestruturado com gestores da IES privada e observações. Dentre os principais achados, verificou-se que as principais estratégicas de crescimento da IES privada estudada se basearam em fusões e aquisições de outras IES, abertura de novos polos de EAD, na abertura de novas unidades próprias, bem como em inovações em várias dimensões da organização. Os programas governamentais de financiamento aos alunos também são fortes contribuintes para este crescimento, como o Fundo de Financiamento ao Estudante do Ensino Superior (FIES) e o Programa Universidade para Todos (Prouni). Com essa nova realidade, o ensino superior privado recebeu incentivo e facilitação para o seu crescimento, a um ritmo acelerado. Consequentemente pode-se concluir que a IES privada estudada adotou as seguintes estratégias de crescimento: Expansão orgânica com fusões/ aquisições de Instituições menores, com desenvolvimento de planos para todos os campi Brasil; Greenfield (por meio de solicitação de autorização de novas unidades e/ou cursos) em cidades sem possibilidades de aquisições/fusões, e aumentando o número de vagas/ matriculas nas unidades já existentes, aderiu aos programas do governo e também cuidou da evasão por meio de: Seguro educacional; gestão preparada para atender necessidades do discente; Sistema de Ensino com currículos integrados nacionalmente; Intercâmbio de alunos e professores entre as diversas unidades em todas as regiões do país e padronização dos processos.

Saberes dos professores da educação profissional técnica de nível médio em enfermagem

A docência na educação profissional técnica de nível médio em enfermagem é uma das dimensões importantes a ser considerada na qualificação da formação de trabalhadores técnicos, no Brasil. Apesar disso, ela é marcada por fragilidade nos processos formativos, adversas condições de trabalho, incluindo, a precariedade. O objetivo deste estudo é descrever e analisar os saberes dos professores de uma escola privada de educação profissional em enfermagem, no município de Ribeirão Preto, considerando suas vivências na prática pedagógica, a partir de referencial de Tardif (2012). Estudo descritivo-exploratório, qualitativo. A técnica de coleta de dados utilizada foi entrevista semiestruturada com 13 professores, realizadas de novembro de 2014 a fevereiro de 2015. As entrevistas foram analisadas, sendo delineadas categorias de decodificação, a saber: Saberes pessoais dos professores; Saberes provenientes da formação escolar anterior; Saberes provenientes da formação profissional para o magistério, subdivididos em Saberes provenientes da formação profissional para o magistério construídos em cursos de Bacharelado e Licenciatura em Enfermagem e Saberes profissionais para o magistério, construídos nos cursos de especialização latu sensu e programas de capacitação docente; Saberes provenientes dos programas e livros didáticos usados no trabalho dos professores; Saberes provenientes de sua própria experiência na profissão envolvendo atuação nos serviços de saúde e na docência. Esses saberes, no exercício cotidiano do trabalho docente, são articulados e reconstruídos. Eles mostram significativamente as suas relações com a diversidade nas possibilidades de formação, dada a fragilidades das políticas de formação docente, bem como suas relações com as condições concretas de trabalho na educação profissional, sendo ainda significativa a concomitância da docência nessa modalidade de ensino com a prática profissional em serviços de saúde, o que também traz implicações para a conformação dos saberes da docência

Persisting to Graduation: A Grounded Theory Exploration of Nontraditional Undergraduate Women's Enrollment

While women maintain a numerical majority in undergraduate college enrollments and degrees earned, they also represent the numerical majority among students over 29 years old, students of color, students who are in the lowest income category, students who are single parents, and students who attend college part-time (Peter & Horn, 2005; Planty, et al., 2008). The National Center for Educational Statistics (NCES) has identified seven characteristics that place students at risk of not completing an undergraduate degree; (a) delayed enrollment between high school and college, (b) part-time enrollment, (c) financial independence, (d) students with dependents, (e) students who are single parents, (f) students who work full-time while enrolled, and (g) students who completed a GED as opposed to earning a high school diploma (Choy, 2002; Dickerson & Stiefer, 2006; Horn & Premo, 1995). The above characteristics overlap with the categories where women have a numerical majority, thereby placing women in greater jeopardy of not completing a bachelor's degree. A review of the existing persistence literature demonstrates a lack of research devoted to understanding the persistence experiences, challenges, strategies, and decisions of nontraditional undergraduate in favor of the "traditional" undergraduate student (Pascarella & Terenzini, 2005; Reason 2003). For this doctoral dissertation, I have based the research on a critical race feminist framework, informed by my experience working with the population of nontraditional undergraduate women at a women's college and employed a critique of the persistence literature as sensitizing concepts. Using a modified grounded theory research design, I collected and analyzed data which led to the development of a grounded theory of nontraditional undergraduate women's persistence. The emergent concepts of commitment, environment, and support interact in a theory of academic momentum and I offer a critical race feminist reading of the findings and theory to expose race neutrality, honor the voices of women of color, and deconstruct the evidence presented. The implications of this research include student, institutional, and inclusive excellence approaches to increasing the persistence of nontraditional undergraduate women and contribute to the success of this unique population of learners.
