Herramienta de medida y visualización de prestaciones basada en eventos para especificaciones RVC-CAL

Este proyecto fin de grado presenta dos herramientas, Papify y Papify-Viewer, para medir y visualizar, respectivamente, las prestaciones a bajo nivel de especificaciones RVC-CAL basándose en eventos hardware. RVC-CAL es un lenguaje de flujo de datos estandarizado por MPEG y utilizado para definir herramientas relacionadas con la codificación de vídeo. La estructura de los programas descritos en RVC-CAL se basa en unidades funcionales llamadas actores, que a su vez se subdividen en funciones o procedimientos llamados acciones. ORCC (Open RVC-CAL Compiler) es un compilador de código abierto que utiliza como entrada descripciones RVC-CAL y genera a partir de ellas código fuente en un lenguaje dado, como por ejemplo C. Internamente, el compilador ORCC se divide en tres etapas distinguibles: front-end, middle-end y back-end. La implementación de Papify consiste en modificar la etapa del back-end del compilador, encargada de la generación de código, de modo tal que los actores, al ser traducidos a lenguaje C, queden instrumentados con PAPI (Performance Application Programing Interface), una herramienta utilizada como interfaz a los registros contadores de rendimiento (PMC) de los procesadores. Además, también se modifica el front-end para permitir identificar cierto tipo de anotaciones en las descripciones RVC-CAL, utilizadas para que el diseñador pueda indicar qué actores o acciones en particular se desean analizar. Los actores instrumentados, además de conservar su funcionalidad original, generan una serie de ficheros que contienen datos sobre los distintos eventos hardware que suceden a lo largo de su ejecución. Los eventos incluidos en estos ficheros son configurables dentro de las anotaciones previamente mencionadas. La segunda herramienta, Papify-Viewer, utiliza los datos generados por Papify y los procesa, obteniendo una representación visual de la información a dos niveles: por un lado, representa cronológicamente la ejecución de la aplicación, distinguiendo cada uno de los actores a lo largo de la misma. Por otro lado, genera estadísticas sobre la cantidad de eventos disparados por acción, actor o núcleo de ejecución y las representa mediante gráficos de barra. Ambas herramientas pueden ser utilizadas en conjunto para verificar el funcionamiento del programa, balancear la carga de los actores o la distribución por núcleos de los mismos, mejorar el rendimiento y diagnosticar problemas. ABSTRACT. This diploma project presents two tools, Papify and Papify-Viewer, used to measure and visualize the low level performance of RVC-CAL specifications based on hardware events. RVC-CAL is a dataflow language standardized by MPEG which is used to define video codec tools. The structure of the applications described in RVC-CAL is based on functional units called actors, which are in turn divided into smaller procedures called actions. ORCC (Open RVC-CAL Compiler) is an open-source compiler capable of transforming RVC-CAL descriptions into source code in a given language, such as C. Internally, the compiler is divided into three distinguishable stages: front-end, middle-end and back-end. Papify’s implementation consists of modifying the compiler’s back-end stage, which is responsible for generating the final source code, so that translated actors in C code are now instrumented with PAPI (Performance Application Programming Interface), a tool that provides an interface to the microprocessor’s performance monitoring counters (PMC). In addition, the front-end is also modified in such a way that allows identification of a certain type of annotations in the RVC-CAL descriptions, allowing the designer to set the actors or actions to be included in the measurement. Besides preserving their initial behavior, the instrumented actors will also generate a set of files containing data about the different events triggered throughout the program’s execution. The events included in these files can be configured inside the previously mentioned annotations. The second tool, Papify-Viewer, makes use of the files generated by Papify to process them and provide a visual representation of the information in two different ways: on one hand, a chronological representation of the application’s execution where each actor has its own timeline. On the other hand, statistical information is generated about the amount of triggered events per action, actor or core. Both tools can be used together to assert the normal functioning of the program, balance the load between actors or cores, improve performance and identify problems.

Metodologías de gestión de proyectos y su implementación en la empresa

Este proyecto ha sido estructurado en tres bloques diferenciados que tiene como objetivo analizar el presente, pasado y futuro de la gestión de proyectos con una orientación clara a ofrecer apoyo a aquellas empresas que planeen realizar un giro en sus estructura de organización de trabajo hacia filosofías ágiles. La gestión de proyectos a acompañado al hombre desde el inicio de los tiempos, pero sin embargo no fue hasta nuestra historia más cercana cuando se comienza a tener conciencia de la necesidad de establecer aplicar métodos generales a la hora de afrontar proyectos de ingeniería. Pioneros fueron en este sentido personajes como Taylor, Fayol o Gantt, cuyas aportaciones iniciales posibilitaron el nacimiento de la gestión de proyectos a mediados del siglo XX. En las década sucesivas hasta nuestros días han aparecido un número considerable de metodologías, perfeccionando elementos anteriormente asimilados y adaptándose a la realidad tecnológica y social del momento. Este recorrido histórico se aborda en el primer bloque de este proyecto. Los puntos revisados en la introducción histórica proporcionan las bases de conocimiento para entender las principales características entre las grandes familias de metodologías que actualmente son implantadas en el mundo empresarial. Es precisamente este punto, el de la exposición y análisis de las metodologías más extendidas y contemporáneas a la elaboración de este proyecto, lo que se aborda en el segundo bloque. En él se desarrolla con intenso detalle dos metodologías de la familia de filosofías ágiles, elegidas entre las más extendidas en la industria: Scrum, eXtreme Programming (XP) y un híbrido de ambas. Para entender la dimensión del cambio filosófico en cuanto a la gestión de proyectos que emprenden estas metodologías, se hace necesario repasar cuales son las metodologías no ágiles más extendidas actualmente. Para ello se introducen metodologías como la llamada tradicional o PRINCE2, principalmente, ya que también se realiza un repaso más superficial por otras aproximaciones notables. El último bloque que construye el desenlace del proyecto, intenta responder a las cuestiones futuras relacionadas con la adopción de metodologías ágiles. Para ello se revisa los puntos más conflictivos a señalar en este proceso y se ofrecerán soluciones teóricas y prácticas para ayudar a las empresas en su fase de migración hacia filosofías de organización ágiles. Ya que toda empresa hoy en día debería tener un soporte tecnológico que ofrezca apoyo a su desarrollo empresarial, gran parte de la elaboración de este proyecto se ha dedicado a hacer un estudio comparativo de las actuales herramientas Open Source. Se han instalado y probado 25 herramientas para posteriormente seleccionar 3 que han sido analizadas en profundidad. Así mismo, se enumeran pros y contras de estas herramientas, aportando ideas de mejoras y trazando cuál debería ser su evolución para ofrecer una alternativa real a las herramientas comerciales orientadas a esta labor. Las empresas pueden utilizar este índice de herramientas de software para decidir si pueden sustentar su proceso de migración en una herramienta Open Source o si deben orientarse a herramientas comerciales o de creación propias. ABSTRACT. This project has been divided into three different blocks that aims to analyze the past, present and future of project management with a clear focus on providing support to those companies that are planning to make a shift in its organizational structure working towards agile philosophies . The project management has walked together with the humanity since the beginning of time , but it was on our recent history when it begins to become aware of the need to establish general methods to apply to engineering projects. There was pioneers like Taylor , Fayol or Gantt, whose contributions made possible the birth of project management in the mid- twentieth century. In the following decades, there was a considerable number of new methodologies, improving concepts and adapting then to the technological and social reality of the moment . This historical journey is addressed in the first block of this project. The different facts reviewed at the first block provide the knowledge to understand the key features among the most important families of methodologies that nowadays are implemented in the business world. It is precisely this point, the presentation and analysis of the most widespread methodologies what is addressed in the second block. Two of the most widespread agile methodologies are detailed: Scrum , eXtreme Programming ( XP ) and a hybrid of both . In order to understand the philosophical shift in terms of project management performed by these methodologies , it is necessary to review what are the most widespread no agile methodologies currently. For this purpose, methodologies like Waterfall or PRINCE2 are explained. Other no agile methodologies are explained as well, but not so deeply in comparison with them. The last section of this project is the conclusion, it tries to answer future questions related to the adoption of agile methodologies. For that reason, the most important milestones are reviewed to provide theoretical and practical solutions and answers to help companies in this migration process toward agile methodologies. Since every company should has a solid technical support for its business development, a considerably part of the time has been applied to make a comparative study of the existing Open Source tools. 25 tools have been installed and tested. Then, 3 tools has been selected to be analyzed deeply. Also, pros and cons of these tools have been exposed in order to suggest a roadmap to offer a real alternative to the existing commercial tools in this business area. The companies that are involved in a migration progress toward a agile methodology can used this study about the available Open Source tools to decide if they can afford the migration process based on one of them or if they should use a commercial tool or a tailor-made software.

Enhanced reproducibility of SADI web service workflows with Galaxy and Docke

Background: Semantic Web technologies have been widely applied in the life sciences, for example by data providers such as OpenLifeData and through web services frameworks such as SADI. The recently reported OpenLifeData2SADI project offers access to the vast OpenLifeData data store through SADI services. Findings: This article describes how to merge data retrieved from OpenLifeData2SADI with other SADI services using the Galaxy bioinformatics analysis platform, thus making this semantic data more amenable to complex analyses. This is demonstrated using a working example, which is made distributable and reproducible through a Docker image that includes SADI tools, along with the data and workflows that constitute the demonstration. Conclusions: The combination of Galaxy and Docker offers a solution for faithfully reproducing and sharing complex data retrieval and analysis workflows based on the SADI Semantic web service design patterns.

Desarrollo de una herramienta de análisis de la señal de voz

El habla es la principal herramienta de comunicación de la que dispone el ser humano que, no sólo le permite expresar su pensamiento y sus sentimientos sino que le distingue como individuo. El análisis de la señal de voz es fundamental para múltiples aplicaciones como pueden ser: síntesis y reconocimiento de habla, codificación, detección de patologías, identificación y reconocimiento de locutor… En el mercado se pueden encontrar herramientas comerciales o de libre distribución para realizar esta tarea. El objetivo de este Proyecto Fin de Grado es reunir varios algoritmos de análisis de la señal de voz en una única herramienta que se manejará a través de un entorno gráfico. Los algoritmos están siendo utilizados en el Grupo de investigación en Aplicaciones MultiMedia y Acústica de la Universidad Politécnica de Madrid para llevar a cabo su tarea investigadora y para ofertar talleres formativos a los alumnos de grado de la Escuela Técnica Superior de Ingeniería y Sistemas de Telecomunicación. Actualmente se ha encontrado alguna dificultad para poder aplicar los algoritmos ya que se han ido desarrollando a lo largo de varios años, por distintas personas y en distintos entornos de programación. Se han adaptado los programas existentes para generar una única herramienta en MATLAB que permite: . Detección de voz . Detección sordo/sonoro . Extracción y revisión manual de frecuencia fundamental de los sonidos sonoros . Extracción y revisión manual de formantes de los sonidos sonoros En todos los casos el usuario puede ajustar los parámetros de análisis y se ha mantenido y, en algunos casos, ampliado la funcionalidad de los algoritmos existentes. Los resultados del análisis se pueden manejar directamente en la aplicación o guardarse en un fichero. Por último se ha escrito el manual de usuario de la aplicación y se ha generado una aplicación independiente que puede instalarse y ejecutarse aunque no se disponga del software o de la versión adecuada de MATLAB. ABSTRACT. The speech is the main communication tool which has the human that as well as allowing to express his thoughts and feelings distinguishes him as an individual. The analysis of speech signal is essential for multiple applications such as: synthesis and recognition of speech, coding, detection of pathologies, identification and speaker recognition… In the market you can find commercial or open source tools to perform this task. The aim of this Final Degree Project is collect several algorithms of speech signal analysis in a single tool which will be managed through a graphical environment. These algorithms are being used in the research group Aplicaciones MultiMedia y Acústica at the Universidad Politécnica de Madrid to carry out its research work and to offer training workshops for students at the Escuela Técnica Superior de Ingeniería y Sistemas de Telecomunicación. Currently some difficulty has been found to be able to apply the algorithms as they have been developing over several years, by different people and in different programming environments. Existing programs have been adapted to generate a single tool in MATLAB that allows: . Voice Detection . Voice/Unvoice Detection . Extraction and manual review of fundamental frequency of voiced sounds . Extraction and manual review formant voiced sounds In all cases the user can adjust the scan settings, we have maintained and in some cases expanded the functionality of existing algorithms. The analysis results can be managed directly in the application or saved to a file. Finally we have written the application user’s manual and it has generated a standalone application that can be installed and run although the user does not have MATLAB software or the appropriate version.

O AGENDAMENTO DE TELEJORNAIS BRASILEIROS EM SITES NOTICIOSOS DE CONTEÚDO COLABORATIVO

The thesis investigates if with the free news production, people who post information on collaborative content sites, known as interacting, tend to reproduce information that was scheduled for Tv news. This study is a comparison of the collaborative content vehicles Vc reporter, Vc no G1 and Eu reporter with TV news SBT Brasil, Jornal Nacional, Jornal da Record and Jornal da Band. We sought to determine whether those newscasts guide the collaborative platforms. The hypothesis assumes that Brazilian TV news have been building over time a credible relationship with the viewer, so it is possible to think that the interacting use the same criteria for selecting the broadcasts and reproduce similar information in collaborative content sites. The method used was content analysis, based on the study of Laurence Bardin and the type of research used was quantitative. This research concluded that, within a small portion of the universe surveyed, there are schedules of television news across the collaborative content.

PlasmoDB: An integrative database of the Plasmodium falciparum genome. Tools for accessing and analyzing finished and unfinished sequence data

The Plasmodium falciparum Genome Database (http://PlasmoDB.org) integrates sequence information, automated analyses and annotation data emerging from the P.falciparum genome sequencing consortium. To date, raw sequence coverage is available for >90% of the genome, and two chromosomes have been finished and annotated. Data in PlasmoDB are organized by chromosome (1–14), and can be accessed using a variety of tools for graphical and text-based browsing or downloaded in various file formats. The GUS (Genomics Unified Schema) implementation of PlasmoDB provides a multi-species genomic relational database, incorporating data from human and mouse, as well as P.falciparum. The relational schema uses a highly structured format to accommodate diverse data sets related to genomic sequence and gene expression. Tools have been designed to facilitate complex biological queries, including many that are specific to Plasmodium parasites and malaria as a disease. Additional projects seek to integrate genomic information with the rich data sets now becoming available for RNA transcription, protein expression, metabolic pathways, genetic and physical mapping, antigenic and population diversity, and phylogenetic relationships with other apicomplexan parasites. The overall goal of PlasmoDB is to facilitate Internet- and CD-ROM-based access to both finished and unfinished sequence information by the global malaria research community.

Cenários de prática no Sistema Único de Saúde e as diretrizes curriculares nacionais para o curso de odontologia

A formação dos profissionais de saúde ainda está distante dos princípios e diretrizes do Sistema Único de Saúde (SUS). As propostas publicadas pelas Diretrizes Curriculares Nacionais (DCN) para o curso de odontologia, em 2002, visam preencher essa lacuna por meio da articulação entre as Instituições de Educação Superior (IES) e o SUS. Trata-se de estudo qualitativo, descritivo e exploratório sobre o sentido das atividades realizadas nos cenários de prática do SUS, sob o ponto de vista dos alunos do curso de odontologia de uma IES privada localizada no interior de São Paulo, à luz das DCN e do projeto político pedagógico (PPP) do referido curso. A pesquisa ocorreu no site da rede social do Facebook, em grupos secretos de discussão com 10 discentes, utilizando questões abertas relacionadas à odontologia, ao SUS e à graduação, entre novembro de 2014 e julho de 2015. Durante o processo, descobriu-se que 8 alunos trabalhavam no SUS como auxiliares e técnicos de saúde bucal e uma auxiliar de enfermagem, fato que influenciou na construção e condução das perguntas. As opiniões dos alunos, o PPP da IES estudada e o documento das DCN foram analisados por meio dos Mapas Conceituais (concebidos por Novak e Cañas), e em seguida, validados, respectivamente, pelos discentes, pelo coordenador do curso de odontologia estudado, e pela representante da Associação Brasileira de Ensino Odontológico (ABENO). Para aprofundar a análise das distintas vivências e pontos de vistas, utilizou-se a técnica de análise de conteúdo temática de Bardin. A discussão dos resultados evidenciou que além de ser possível ocorrer práticas pedagógicas nos cenários de prática do SUS, também é provável o aprendizado de competências e habilidades descritas pelas DCN. O potencial transformador desses cenários de prática possibilitou, nessa pesquisa, a proposição de estratégias para a realização de atividades no SUS alinhadas às DCN.

Particle Swarm Optimization Based Reactive Power Dispatch for Power Networks with Distributed Generation

Reactive power is critical to the operation of the power networks on both safety aspects and economic aspects. Unreasonable distribution of the reactive power would severely affect the power quality of the power networks and increases the transmission loss. Currently, the most economical and practical approach to minimizing the real power loss remains using reactive power dispatch method. Reactive power dispatch problem is nonlinear and has both equality constraints and inequality constraints. In this thesis, PSO algorithm and MATPOWER 5.1 toolbox are applied to solve the reactive power dispatch problem. PSO is a global optimization technique that is equipped with excellent searching capability. The biggest advantage of PSO is that the efficiency of PSO is less sensitive to the complexity of the objective function. MATPOWER 5.1 is an open source MATLAB toolbox focusing on solving the power flow problems. The benefit of MATPOWER is that its code can be easily used and modified. The proposed method in this thesis minimizes the real power loss in a practical power system and determines the optimal placement of a new installed DG. IEEE 14 bus system is used to evaluate the performance. Test results show the effectiveness of the proposed method.

Development and programming of Geophonino: A low cost Arduino-based seismic recorder for vertical geophones

The commercial data acquisition systems used for seismic exploration are usually expensive equipment. In this work, a low cost data acquisition system (Geophonino) has been developed for recording seismic signals from a vertical geophone. The signal goes first through an instrumentation amplifier, INA155, which is suitable for low amplitude signals like the seismic noise, and an anti-aliasing filter based on the MAX7404 switched-capacitor filter. After that, the amplified and filtered signal is digitized and processed by Arduino Due and registered in an SD memory card. Geophonino is configured for continuous registering, where the sampling frequency, the amplitude gain and the registering time are user-defined. The complete prototype is an open source and open hardware system. It has been tested by comparing the registered signals with the ones obtained through different commercial data recording systems and different kind of geophones. The obtained results show good correlation between the tested measurements, presenting Geophonino as a low-cost alternative system for seismic data recording.

Integrated architecture for vision-based indoor localization and mapping of a quadrotor micro-air vehicle

Atualmente os sistemas de pilotagem autónoma de quadricópteros estão a ser desenvolvidos de forma a efetuarem navegação em espaços exteriores, onde o sinal de GPS pode ser utilizado para definir waypoints de navegação, modos de position e altitude hold, returning home, entre outros. Contudo, o problema de navegação autónoma em espaços fechados sem que se utilize um sistema de posicionamento global dentro de uma sala, subsiste como um problema desafiante e sem solução fechada. Grande parte das soluções são baseadas em sensores dispendiosos, como o LIDAR ou como sistemas de posicionamento externos (p.ex. Vicon, Optitrack). Algumas destas soluções reservam a capacidade de processamento de dados dos sensores e dos algoritmos mais exigentes para sistemas de computação exteriores ao veículo, o que também retira a componente de autonomia total que se pretende num veículo com estas características. O objetivo desta tese pretende, assim, a preparação de um sistema aéreo não-tripulado de pequeno porte, nomeadamente um quadricóptero, que integre diferentes módulos que lhe permitam simultânea localização e mapeamento em espaços interiores onde o sinal GPS ´e negado, utilizando, para tal, uma câmara RGB-D, em conjunto com outros sensores internos e externos do quadricóptero, integrados num sistema que processa o posicionamento baseado em visão e com o qual se pretende que efectue, num futuro próximo, planeamento de movimento para navegação. O resultado deste trabalho foi uma arquitetura integrada para análise de módulos de localização, mapeamento e navegação, baseada em hardware aberto e barato e frameworks state-of-the-art disponíveis em código aberto. Foi também possível testar parcialmente alguns módulos de localização, sob certas condições de ensaio e certos parâmetros dos algoritmos. A capacidade de mapeamento da framework também foi testada e aprovada. A framework obtida encontra-se pronta para navegação, necessitando apenas de alguns ajustes e testes.
