Sistema de telemetría para un vehículo de fórmula S.A.E.

En este proyecto, se ha desarrollado una aplicación electrónica para un coche de competición, en concreto para la fórmula SAE (Society of Automotive Engineers), una competición universitaria en la que cada equipo, formado por estudiantes, debe diseñar, construir y probar un prototipo basándose en una serie de reglas. El objetivo final de la competición es proporcionar a los estudiantes el conocimiento práctico necesario para su futura labor profesional, del cual se pensaba que los estudiantes adolecían al acabar sus estudios universitarios cuando se creó esta competición. La aplicación desarrollada en este proyecto consiste en un sistema de telemetría, utilizado para transmitir los datos proporcionados por los sensores del vehículo a través de un sistema de radiofrecuencia, de manera que se pueda estudiar el comportamiento del coche durante los ensayos a la vez que el coche está rodando y así no depender de un sistema de adquisición de datos del que había que descargarse la información una vez finalizada la sesión de ensayo, como había que hacer hasta el momento. Para la implementación del proyecto, se ha utilizado un kit de desarrollo (Xbee Pro 868) que incluye dos módulos de radio, dos placas de desarrollo, dos cables USB y una antena, el cual ha permitido desarrollar la parte de radio del proyecto. Para transmitir los datos proporcionados por la centralita del vehículo, la cual recoge la información de todos los sensores presentes en el vehículo, se han desarrollado dos placas de circuito impreso. La primera de ellas tiene como elemento principal un microprocesador PIC de la marca Microchip (PIC24HJ64GP502), que recoge los datos proporcionados por la centralita del vehículo a través de su bus CAN de comunicaciones. La segunda placa de circuito impreso tiene como elemento fundamental el transmisor de radio. Dicho transmisor está conectado al microprocesador de la otra placa a través de línea serie. Como receptor de radio se ha utilizado una de las placas de prueba que integraba el kit de desarrollo Xbee Pro 868, la cual recoge los datos que han sido enviados vía radio y los manda a su vez a través de USB a un ordenador donde son monitorizados. Hasta aquí la parte hardware del sistema. En cuanto a la parte software, ha habido que desarrollar una aplicación en lenguaje C, que ejecuta el microprocesador PIC, que se encarga de recoger los datos enviados por la centralita a través del bus CAN (Controller Area Network) y transmitirlos a través de línea serie al chip de radio. Por último, para la monitorización de los datos se han desarrollado dos aplicaciones en LabVIEW, una que recoge los datos a través de USB, los muestra en pantalla y los guarda en un fichero y otra que lee los datos del fichero y los representa gráficamente para permitir un estudio más detallado del comportamiento del vehículo. ABSTRACT In this project, an electronic application has been developed for a race car – Formula SAE car-. Formula SAE is a university championship in which each team, made up of students, should design, construct and test a prototype within certain rules. The final goal of the competition is to enhance the practical knowledge of the students, which was thougth to be poor at the time the competition was created. The application developed in this project consists of a telemetry system, employed to transmit the data provided by the car’s sensors through a radio frequency system, so that it could be possible to study the behaviour of the vehicle during tests and do not depend on a datalogger system as it occurred until now. To carry out the radio module of the project, a Xbee Pro 868 development kit has been used, which includes two radio modules, two development boards, two USB cables and an antenna. To transmit the data provided by the ECU (Engine Control Unit) of the vehicle, which receives information from all the sensors the vehicle has, two printed circuit boards have been built. One of them has a PIC microprocessor of Microchip (PIC24HJ64GP502) which receives the data coming from CAN bus of the ECU. Tha main element of the other printed circuit board is the radio transmitter. This chip receives the data from the microprocessor through its serial line. The development board of the Xbee Pro 868 has been used as receiver. When data arrives to the receiver, it transmits them to a computer through USB where the data are displayed. All this composes the hardware of the system. Regarding the software, a C coded application has been developed. This application is executed by the microprocessor and its function is to receive the data from the bus CAN (Controller Area Network) and send them to the radio transmitter through the microprocessor’s serial line. To show the data on the computer, two LabVIEW applications has been developed. The first one receives the data through the USB port, displays them on the screen and save them to a file and the second one reads the data from the file while represents them graphically to allow studying the behaviour of the car on track.

Determining the effectiveness of three software evaluation techniques through informal aggregation

An accepted fact in software engineering is that software must undergo verification and validation process during development to ascertain and improve its quality level. But there are too many techniques than a single developer could master, yet, it is impossible to be certain that software is free of defects. So, it is crucial for developers to be able to choose from available evaluation techniques, the one most suitable and likely to yield optimum quality results for different products. Though, some knowledge is available on the strengths and weaknesses of the available software quality assurance techniques but not much is known yet on the relationship between different techniques and contextual behavior of the techniques. Objective: This research investigates the effectiveness of two testing techniques ? equivalence class partitioning and decision coverage and one review technique ? code review by abstraction, in terms of their fault detection capability. This will be used to strengthen the practical knowledge available on these techniques.

A personal data framework for exchanging knowledge about users in new financial services

Personal data is a key asset for many companies, since this is the essence in providing personalized services. Not all companies, and specifically new entrants to the markets, have the opportunity to access the data they need to run their business. In this paper, we describe a comprehensive personal data framework that allows service providers to share and exchange personal data and knowledge about users, while facilitating users to decide who can access which data and why. We analyze the challenges related to personal data collection, integration, retrieval, and identity and privacy management, and present the framework architecture that addresses them. We also include the validation of the framework in a banking scenario, where social and financial data is collected and properly combined to generate new socio-economic knowledge about users that is then used by a personal lending service.

Handy or practical student. Objective: to pass or to learn

With the introduction of the European Higher Education Area and the development of the "Bologna" method in learning certain technological subjects, a pilot assessment procedure was launched in the "old" plan to observe, monitor and analyze the acquiring knowledge of senior students in various academic courses. This paper is a reflection on culture and knowledge. Will students accommodate to get a lower score on tests because they know they have a lot of tooltips to achieve their objectives?. Are their skills lower for these reason?.

Educating in Project Management: an innovative approach. A shared-experience among Spanish Universities

This work presents an educational formal initiative aimed to monitor the acquisition and strengthening of competences by students that are being taught in project management subject. Groups of students belonging to three universities, embracing different knowledge areas such as engineering, biology, etc., were selected to run the experience. All of them had nevertheless a common and basic starting point: inexperience in project management field. In this scenario, we propose a new theoretical and practical approach oriented to reinforce problem-solving and related competences in a project management subject context. For this purpose, a Project-Based Learning (PjBL) initiative has been specifically designed and developed. The main idea is to bring a real world engineering project management case into the classroom, where students must face up to a completely new learning approach –groups in different locations, collaborative mode and unspecific solution, supported by a powerful internet platform:.project.net (http://www.Project.net). Other relevant aspects such as project climate, knowledge increasing, have also been monitored during the course. Results show and overall improvement in key competences. The obtained information will be used in two ways: to feed the students back about personal opportunities for improvement in specific competences, and to fine-tune the experience for further initiatives.

Knowledge Management and Information Systems based on Workflow Technology

Knowledge management is critical for the success of virtual communities, especially in the case of distributed working groups. A representative example of this scenario is the distributed software development, where it is necessary an optimal coordination to avoid common problems such as duplicated work. In this paper the feasibility of using the workflow technology as a knowledge management system is discussed, and a practical use case is presented. This use case is an information system that has been deployed within a banking environment. It combines common workflow technology with a new conception of the interaction among participants through the extension of existing definition languages.

Arquitectura óptima: Cuatro medios prácticos para optimizar proyectos de arquitectura

La investigación trata de mostrar cuatro acciones habitualmente empleadas al proyectar arquitectura. La tesis narra el discurso que construyen cuatro acciones como mecanismos optimizadores, fundamentales, activos y necesarios cuando creamos nuevos proyectos. En este trabajo se estudian en profundidad cuatro acciones optimizadoras a través de numerosos casos de estudio. Se estudia también la presencia de estas acciones en otros campos creativos, como la biología, el arte, la literatura, la filosofía, la matemática o la psicología de la creatividad. Se busca qué tienen en común estas cuatro acciones y se indaga sobre la posible narración que construyen entre ellas. La mayor parte de los textos que constituyen este trabajo se escriben en un formato próximo al del ensayo, empleando tiempos verbales presentes evitando los tiempos verbales pretéritos o imperfectos para potenciar la acción a través el estilo narrativo. La investigación se ha realizado a partir de fuentes bibliográficas existentes en numerosas bibliotecas. Se han llevado a cabo estudios de campo realizados a través de entrevistas personales a interlocutores expertos, no sólo de teoría arquitectónica sino también de prácticas constructivas, así como visitas a lugares íntimamente relacionados con el tema de investigación. Se ha completado el estudio de casos con ejercicios prácticos realizados por el autor de esta tesis, para profundizar con la propia investigación por empatía con los autores estudiados. La investigación bibliográfica principal se ha desarrollado en las bibliotecas de la Universidad Politécnica de Madrid, de la Universidad de Alicante, de la Universidad Autónoma de Madrid, de la Universidad Europea de Madrid, de la Universidad Camilo José Cela, de la Universidad Complutense de Madrid, de la Columbia University, de la Harvard University, de la Delft University, de Heidelberg University, de la Biblioteca Central de Madrid y de la Regional de Murcia, así como de la del COAMU. También se ha utilizado recursos bibliográficos propios. La metodología utilizada muestra desde diferentes perspectivas el problema de las acciones optimizadoras, desde obras artísticas, pasando por ejemplos de arquitectura construida hasta ejercicios puramente intelectuales. La acumulación ha sido el método de obtención de conocimiento de esta tesis. Se han acumulado conocimientos y posteriormente se ha profundizado, reflexionando sobre los datos que se han ido obteniendo. Al profundizar se enlazan unas pruebas con otras, hilando y ensamblándolas en un discurso que hace continuo y coherente la aparición de cada caso estudiado. Estas entidades probatorias son acciones que han sido aplicadas frecuentemente por distintas generaciones de autores que proyectan utilizando alguna de estas cuatro acciones. Partimos de una extensa bibliografía general y de otra específica. A través de citas e imágenes se muestra el repertorio de objetos y textos estudiados. Los casos de estudio seleccionados exponen los efectos que produce cada acción en el ejercicio del proyectar. Se ha estudiado la necesidad de cada acción en todas y cada una de las partes del ciclo creativo del proyecto, tanto en prácticas imaginadas como en construidas, de los autores que proyectan. Se citan y se interpretan las descripciones de biólogos, sociólogos, antropólogos, psicólogos, escritores, artistas, arquitectos, matemáticos, ingenieros, físicos, médicos y filósofos en los cuales estas acciones se encuentran conscientemente incorporadas en su procedimiento de proyectar y de pensar. Por último, hemos obtenido unos resultados adecuados a la metodología empleada y a los objetivos planteados gracias a la acumulación y clasificación de pruebas. Los resultados se exponen a modo de discursos conclusivos con un intencionado carácter abierto que despliega nuevas posibles nuevas vías de investigación entorno a los temas estudiados. ABSTRACT. The research seeks to show four commonly used actions in designing architecture. Thesis recounts the speech that built four actions like optimizer, fundamental, active and necessary mechanisms when we create new projects. In this work it studies in depth four optimizer actions through numerous case studies. Also, it considers the presence of these actions in other creative fields, such as biology, art, literature, philosophy, mathematics or psychology of creativity. It is intended what these four actions have in common and it explores the possible narrative constructed among them. Most of the texts that constitute this work are written in a format close to the essay, using present tenses avoiding past or imperfect tenses of enhancing the action through the narrative style. Research has been done from literature sources available in numerous libraries. Field studies have been carried out through personal interviews with expert speakers, not just of architectonic theory but also from constructive practices, as well as visits to sites closely related to the research topic. case studies with practical exercises conducted by the author of this thesis has been completed, to deepen with the own research by empathy with the studied authors. Main bibliographical investigation has been developed in the libraries of UPM, UA, UAM, UEM, the CJC, the UCM, Columbia University, Harvard University Delft University, Heidelberg University, Madrid Central Library, Regional Murcia Library and COAMU Library. Also it has been used own bibliographical resources. Methodology shows from different perspectives the problem of optimizers actions, from art, passing through examples of architecture built up to puré intellectual exercise. Accumulation has been the method of obtaining knowledge of this thesis. it has been accumulated knowledge and later it has been deepened, reflecting on the data that have been obtained. By deepening tests are linked with other, spinning and locking into a discourse that makes continuous and consistent the development of each case study. These evidentiary entities are actions that have been frequently applied by different generations of authors who project using some of these four stocks. We leave from an extensive general bibliography and another specific one. Through quotes and pictures it shows the repertoire of objects and texts studied. The selected study cases set out the effects that each action produces in the exercise of projecting. It has studied the need of each action in every parts of creative cycle of the project, both imagined as constructed practices, by the authors who project. It is quoted and interpreted the descriptions of biologists, sociologists, anthropologists, psychologists, writers, artists, architects, mathematicians, engineers, physicists, physicians and philosophers in which these actions are consciously incorporated into his projecting and thinking procedure. Finally, we have obtained adequate results to the used methodology and to the stated objectives through the accumulation and classification of evidence. The results are presented as conclusive speeches with an intentional open character that unfolds new possible research routes around the studied topics.

Survey on integration of Applied Geology and Geomorphology in Civil Engineering curricula in the framework of the European Higher Education Area (EHEA) by using practical trips

The engineer must have sufficient theoretical knowledge to be applied to solve specific problems, with the necessary capacity to simplify these approaches, and taking into account factors such as speed, simplicity, quality and economy. In Geology, its ultimate goal is the exploration of the history of the geological events through observation, deduction, reasoning and, in exceptional cases by the direct underground exploration or experimentation. Experimentation is very limited in Geology. Reproduction laboratory of certain phenomena or geological processes is difficult because both time and space become a large scale. For this reason, some Earth Sciences are in a nearly descriptive stage whereas others closest to the experimental, Geophysics and Geochemistry, have assimilated progress experienced by the physics and chemistry. Thus, Anglo-Saxon countries clearly separate Engineering Geology from Geological Engineering, i.e. Applied Geology to the Geological Engineering concepts. Although there is a big professional overlap, the first one corresponds to scientific approach, while the last one corresponds to a technological one. Applied Geology to Engineering could be defined as the Science and Applied Geology to the design, construction and performance of engineering infrastructures in and field geology discipline. There has been much discussion on the primacy of theory over practice. Today prevails the exaggeration of practice, but you get good workers and routine and mediocre teachers. This idea forgets too that teaching problem is a problem of right balance. The approach of the action lines on the European Higher Education Area (EHEA) framework provides for such balance. Applied Geology subject represents the first real contact with the physical environment with the practice profession and works. Besides, the situation of the topic in the first trace of Study Plans for many students implies the link to other subjects and topics of the career (tunnels, dams, groundwater, roads, etc). This work analyses in depth the justification of such practical trips. It shows the criteria and methods of planning and the result which manifests itself in pupils. Once practical trips experience developed, the objective work tries to know about results and changes on student’s motivation in learning perspective. This is done regardless of the outcome of their knowledge achievements assessed properly and they are not subject to such work. For this objective, it has been designed a survey about their motivation before and after trip. Survey was made by the Unidad Docente de Geología Aplicada of the Departamento de Ingeniería y Morfología del Terreno (Escuela Técnica Superior de Ingenieros de Caminos, Canales y Puertos, Universidad Politécnica de Madrid). It was completely anonymous. Its objective was to collect the opinion of the student as a key agent of learning and teaching of the subject. All the work takes place under new teaching/learning criteria approach at the European framework in Higher Education. The results are exceptionally good with 90% of student’s participation and with very high scores in a number of questions as the itineraries, teachers and visited places (range of 4.5 to 4.2 in a 5 points scale). The majority of students are very satisfied (average of 4.5 in a 5 points scale).

A knowledge based framework to support active aging at home based environments

Information and Communication Technologies can support Active Aging strategies in a scenario like the Smart Home. This paper details a person centered distributed framework, called TALISMAN+, whose aim is to promote personal autonomy by taking advantage of knowledge based technologies, sensors networks, mobile devices and internet. The proposed solution can support an elderly person to keep living alone at his house without being obliged to move to a residential center. The framework is composed by five subsystems: a reasoning module that is able to take local decisions at home in order to support active aging, a biomedical variables telemonitorisation platform running on a mobile device, a hybrid reasoning middleware aimed to assess cardiovascular risk in a remote way, a private vision based sensor subsystem, and a secure telematics solution that guarantees confidentiality for personal information. TALISMAN+ framework deployment is being evaluated at a real environment like the Accessible Digital Home.

Clustering techniques for patients suffering acquired brain injury inneuro personal trainer

The study of the effectiveness of the cognitive rehabilitation processes and the identification of cognitive profiles, in order to define comparable populations, is a controversial area, but concurrently it is strongly needed in order to improve therapies. There is limited evidence about cognitive rehabilitation efficacy. Many of the trials conclude that in spite of an apparent clinical good response, differences do not show statistical significance. The common feature in all these trials is heterogeneity among populations. In this situation, observational studies on very well controlled cohort of studies, together with innovative methods in knowledge extraction, could provide methodological insights for the design of more accurate comparative trials. Some correlation studies between neuropsychological tests and patients capacities have been carried out -1---2- and also correlation between tests and morphological changes in the brain -3-. The procedures efficacy depends on three main factors: the affectation profile, the scheduled tasks and the execution results. The relationship between them makes up the cognitive rehabilitation as a discipline, but its structure is not properly defined. In this work we present a clustering method used in Neuro Personal Trainer (NPT) to group patients into cognitive profiles using data mining techniques. The system uses these clusters to personalize treatments, using the patients assigned cluster to select which tasks are more suitable for its concrete needs, by comparing the results obtained in the past by patients with the same profile.

Survey on student motivation and approval of educational environment at Universidad Politécnica de Madrid within the European Higher Education area implementation

A recent study elaborated by Vicerrectorado de Ordenación Académica y Planificación Estratégica of Technical University of Madrid (UPM) defines the satisfaction of the university student body as "the response that the University offers to the expectations and demands of service of the students, considered in a general way ". Besides an indicator of academic and institutional insertion of the student, the assessment of student engagement allows us to adapt the academic offer and the extension services of the University to the real needs of the students. The process of convergence towards the European Higher Education Area (EHEA) raises the need to form in competitions, that is to say, of developing in our students capacities and knowledge beyond the purely theoretical-practical thing. Therefore, the perception and experience of the educational process and environment by the students is an important issue to be addressed to accomplish their expectations and achieve a curriculum accordingly to EHEA expectations. The present study aims to explore the student motivation and approval of the educational environment at the UPM. To this end a total of 97 students enrolled in the undergraduate program of Civil Engineering, Computer Engineering and Agronomic Engineering at UPM were surveyed. The survey consisted of 40 questions divided in three blocks. The first one of 20 questions of personal character in that they were gathering, besides the sex and the age, the degree of fulfilment, implication and dedication with the institution and the academic tasks. In the second block we identify 10 questions related to the perception of the student on the teaching quality, and finally a block of 10 questions regarding the Bologna Process. The students personal motivation was moderately high, with a score of 3.6 (all scores are provided on a 5-point scale), being the most valuable items obtaining a university degree (4,3) and the friendship between students (4,2). Any significant difference was shown between sexes (P=0.23) since the averages for this block of questions were of 3.7±0.3 and 3.5±0.4 for women and men respectively. The students are moderately satisfied with their graduate studies with an average score of 3,2, being the questions that reflect a minor satisfaction the research profile of the teachers (2,8) and the organization of the Schools (2,9). The best valued questions are related to the usefulness and quality of the degrees, with 3,5 and 3,4 respectively, and to the interest of the courses within the degree (3,4). For sexes, the results of this block of questions are similar (3.1±0.3 and 3.2±0.3 for men and women respectively=0.79). Also, there were no differences (P=0.39) between the students who arrange work and studies or do not work (3.1±0.2 and 3.2±0.3 respectively). In conclusion, students at UPM present an acceptable degree of motivation and satisfaction with regard to the studies and services that offer their respective Schools. Both characteristics receive the same value both for men and for women and so much for students who arrange work and studies as for those who devote themselves only to studying. In a significant way, students who are more engaged and are in-class attendants present the major degree of satisfaction.Overall, there is a great lack of information regarding the Bologna Process. In fact to the majority, they would like to know more on what it is, what it means and what changes will involve its implementation.

Integration of multisensor hybrid reasoners to support personal autonomy in the smart home.

The deployment of the Ambient Intelligence (AmI) paradigm requires designing and integrating user-centered smart environments to assist people in their daily life activities. This research paper details an integration and validation of multiple heterogeneous sensors with hybrid reasoners that support decision making in order to monitor personal and environmental data at a smart home in a private way. The results innovate on knowledge-based platforms, distributed sensors, connected objects, accessibility and authentication methods to promote independent living for elderly people. TALISMAN+, the AmI framework deployed, integrates four subsystems in the smart home: (i) a mobile biomedical telemonitoring platform to provide elderly patients with continuous disease management; (ii) an integration middleware that allows context capture from heterogeneous sensors to program environment¿s reaction; (iii) a vision system for intelligent monitoring of daily activities in the home; and (iv) an ontologies-based integrated reasoning platform to trigger local actions and manage private information in the smart home. The framework was integrated in two real running environments, the UPM Accessible Digital Home and MetalTIC house, and successfully validated by five experts in home care, elderly people and personal autonomy.

Creating and modelling personal socio-economic networks in on-line banking

The banking industry is observing how new competitors threaten its millennial business model by targeting unbanked people, offering new financial services to their customer base, and even enabling new channels for existing services and customers. The knowledge on users, their behaviour, and expectations become a key asset in this new context. Well aware of this situation, the Center for Open Middleware, a joint technology center created by Santander Bank and Universidad Politécnica de Madrid, has launched a set of initiatives to allow the experimental analysis and management of socio-economic information. PosdataP2P service is one of them, which seeks to model the economic ties between the holders of university smart cards, leveraging on the social networks the holders are subscribed to. In this paper we describe the design principles guiding the development of the system, its architecture and some implementation details.

Language resources and linked data: a practical perspective

Recently, experts and practitioners in language resources have started recognizing the benefits of the linked data (LD) paradigm for the representation and exploitation of linguistic data on the Web. The adoption of the LD principles is leading to an emerging ecosystem of multilingual open resources that conform to the Linguistic Linked Open Data Cloud, in which datasets of linguistic data are interconnected and represented following common vocabularies, which facilitates linguistic information discovery, integration and access. In order to contribute to this initiative, this paper summarizes several key aspects of the representation of linguistic information as linked data from a practical perspective. The main goal of this document is to provide the basic ideas and tools for migrating language resources (lexicons, corpora, etc.) as LD on the Web and to develop some useful NLP tasks with them (e.g., word sense disambiguation). Such material was the basis of a tutorial imparted at the EKAW’14 conference, which is also reported in the paper.

Personal data usage management

Personal data about users (customers) is a key component for enterprises and large organizations. Its correct analysis and processing can produce relevant knowledge to achieve different business goals. For example, the monetisation of this data has become a valuable asset for many companies, such as Google, Facebook or Twitter, that obtain huge profits mainly from targeted advertising.
