Project file archives are becoming increasingly large. The number of files, information and data that need to be created, accessed and modified throughout a project can be overwhelming. It is critical for project participants or contributors to find relevant information in project archives quickly. In this thesis, I present VisArchive, an interactive visualization tool that provides users with better awareness of search results within project archives. VisArchive visualizes the relevance-ranked search results with a color-coded stacked bar chart and interactive timelines and provides supporting visual cues to help differentiate search results based on searched keywords. It aims to allow users to interactively search, browse, and explore information in project archives, including access history, effectively and efficiently. I will present two case studies to illustrate how VisArchive can be used to support searching, browsing, and exploring information in building construction and open source software projects. In addition, I discuss how VisArchive can be improved to address information retrieval problems and work across different domains. VisArchive demonstrates the combination and application of several visualization techniques to the problem of searching and navigating project archives. / Graduate / 0984

This dissertation entailed a qualitative case study on the confluence of technology and social studies in fostering a constructivist education. Through the examination of pre-service social studies teachers’ understanding of the online primary source resources (OPSR), three themes emerged. The first exposed the fragmented understanding of important pedagogical theories of constructivism and historical thinking among participants; the second suggested that OPSR was mostly valued by pre-service teachers for its provision of primary sources; and the third related to how pre-service teachers viewed the current state of technology and context as problematic for technology integration. Accordingly, four findings were revealed. First, the pre-service teachers in the study demonstrated a limited understanding of the application of foundational theories central to their field of study; second, there were instances of deeper appreciation of the potential of OPSR, indicating that pre-service teachers’ theoretical understanding is ix nascent and may deepen overtime; third, the full potential of technologies such as OPSR was not recognized; and fourth, the pre-service teachers’ perceptions of school and educational system conditions tended to negatively influence their views toward the integration of technology into their teaching practices. Implications indicate that first, foundational pedagogical theories are critical with regard to technology integration in education and as such teacher preparation programs must not assume what is taught is what is learned; second, instances of deeper understanding among pre-service teachers only appeared during the application of their theoretical understandings; third, context is critical in how OPSR would be used in classrooms and such contextual issues must not be ignored by teacher preparation programs; and fourth, teachers’ technological pedagogical content knowledge (PCK/TPCK) is critical in the integration of technology in education. / text

Le peuplement ancien des régions allant de l’Iran à l’Inde en passant par l’Afghanistan et le Turkménistan est connu majoritairement par des échanges transrégionaux existant probablement dès le Néolithique. Du point de vue funéraire, les éléments accompagnant le défunt sont parmi les plus étudiés. En revanche, il est bien souvent peu fait état de leur contexte, à savoir la tombe et le défunt auquel ce mobilier était dédié. C’est en partant de ces constats qu’il est apparu intéressant d’enquêter sur ces peuplements anciens. À partir d’une étude approfondie des sépultures, cette étude se propose de reconstruire les programmes funéraires qui ont encadré les différentes pratiques mortuaires. Dans un second temps, nous avons cherché à souligner les traits funéraires communs de ces populations ainsi que les divergences. Sur l’ensemble du Balochistan pakistanais, seuls quatre sites ont livré des sépultures attribuables à la période Chalcolithique. Les sites de Miri Qalat et Shahi‐Tump ont livré plus de 200 individus répartis sur deux périodes pour le IVe millénaire. Sur le site de Sohr Damb, à Nal, un total d’une centaine d’individus sont dénombrés pour deux périodes situées au IVe et tout début du IIIe millénaire. Ces trois sites aux données inédites sont le cœur de cette étude. Nous avons rapproché nos conclusions des publications effectuées pour le site de Mehrgarh, où deux ensembles funéraires ont été étudiés, ainsi que des données publiées pour les pays limitrophes. / The old settlements of the areas extending from Iran to India including Afghanistan and Turkmenistanare mainly known through transregional exchanges existing probably as early as Neolithic. From the funerarypoint of view, grave goods are among the most studied items. On the other hand, there is often little mentionof their context, namely the tomb and the deceased to whom those grave goods were dedicated. It was fromthese observations that it became interesting to work on these ancient stands. Based on an in‐depth study ofburials, this work proposes to reconstruct the funeral programs that have framed the various mortuarypractices. In a second step, we sought to highlight the common funeral traits of these populations as well asthe differences. On the whole of the Pakistani Balochistan, only four sites yielded tombs related to theChalcolithic period. The sites of Miri Qalat and Shahi‐Tump, have delivered over 200 individuals spread overtwo periods for the fourth millennium. At the Sohr Damb site, in Nal, about 100 individuals are counted for twoperiods in the fourth and early third millennium. These three sites with unpublished data are the heart of thisstudy. We have compared our findings with publications for the Mehrgarh site, where two cemeteries werestudied, as well as published data for neighboring areas.

Complex software systems are difficult to understand and very hard to debug. Programmers trying to understand or debug these systems must read through source code which may span over thousands of files. Software Visualization tries to ease this burden by using graphics and animation to convey important information about the program to the user, which may be used either for understanding the behavior of the program or for detecting any defects within the code. SoftViz is one such software visualization system, developed by Ben Kurtz under the guidance of Prof. George T. Heineman at WPI. We carry forward the work initiated with SoftViz. Our preliminary study showed various avenues for making the system more effective and user-friendly. Specifically I completed the unfinished work, made optimizations, implemented new functionality and added new visualization plug-ins, all aimed at making the system a more versatile and user-friendly debugging framework. We built a solid core functionality that would be able to support various functionalities and created new plug-ins that would make understanding and bug-detection easier. Further we integrated SoftViz with the Eclipse development environment, making the system easily accessible and potentially widely used. We created an error classification framework relating the common error classes and the visualizations that could be used to detect them. We believe this will be helpful in both selecting the right visualization options as well as constructing new plug-ins.

No. of bitstreams: 1 tiagomachado.pdf: 31043362 bytes, checksum: 9a351916809d0428a7cfe66da526a87c (MD5) Previous issue date: 2015-09-04 / Recentemente, tem crescido a preocupação das emissoras de TV em como adaptar seus fluxos de trabalho de modo a produzir e entregar conteúdo interativo de qualidade no ambiente de TV Digital. Devido às mudanças e custos necessários para a implantação da nova tecnologia, as emissoras acabam por não explorar plenamente as possibilidades de interatividade. Assim, para que o usuário tenha acesso a uma experiência avançada e agradável, é necessário otimizar a produção de conteúdo interativo e diminuir seus custos. Para isto, novas soluções capazes de prover uma maior automação na produção de conteúdo interativo devem ser investigadas. Neste contexto, este trabalho propõe um sistema para detecção de objetos durante a produção de cenas de vídeo, capaz de capturar objetos e associar a captura a metadados relacionados durante filmagens, em estúdio de gravação ou mesmo em eventos ao vivo. A informação capturada é entregue de forma estruturada, na chamada linha do tempo de objetos, a qual pode ser manipulada durante todos os estágios de edição do vídeo, bem como na criação de conteúdo interativo. / Recently, TV Broadcasters have been concerned on how to adapt their workflow in order to produce and deliver high quality interactive content in the Digital TV environment. Due to the changes and costs needed for the deployment of this new technology, broadcasters do not fully explore the possibilities of interactivity. Therefore, in order to provide users an enhanced and pleasing user experience, they are required to optimize the production of interactive content and lower its costs. For this reason, new solutions able to provide a higher level of automation for interactive content production must be investigated. In this context, this work proposes an object detection method able to capture objects and related metadata during video shooting in a recording studio or even on a live event. Captured information is delivered in a structured manner, the so-called object timeline, which may be handled throughout the stages of video editing as well as during the creation of interactive content.

In the scope of the master's project which is documented with the present thesis a mission planning tool (MPT) for SONATE was developed and implemented. After a thorough research on the current state of the art of MPTs and taking especially the early stage of the SONATE mission into account, it was decided to develop a generic timeline-based MPT. In contrast to existing MPTs a system is envisioned which is both powerful, regarding advanced features like resource control, and applicable for small satellite missions regarding the overall complexity and the associated configuration and training effort. Although it was obvious from an early stage that this vision cannot be reached in the scope of this project, it was kept during the project definition, object oriented analysis and early design stages in order to allow future extensions. Also the decision to develop the MPT on top of the Eclipse Rich Client Platform is mainly due to the argument of future extensibility. The MPT, which is released with this thesis, hence is a very basic generic timeline-based MPT omitting all possible advanced features like resource control or procedure validation, but featuring all essential parts of a MPT, i.e. modelling of procedures, scheduling of activities, and the generation of telecommand sequences. Furthermore, the user is supported by an intuitive graphical user interface. The thesis documents the development process, thus giving a broad understanding of the design and the implementation. For specific details of the implementation one may also refer to the separate technical documentation, while a user handbook included as appendix. The characteristics of the SONATE mission as a technology demonstrator for highly autonomous systems raise several important questions regarding the overall mission planning process. Therefore, besides the actual development of the MPT, those questions are discussed in a theoretical manner in the scope of this thesis, taking also account of the general emergence of highly autonomous satellites systems.Three concepts, Safe Planning, Sigma Resource Propagation, and Direct Telemetry Feedback, are proposed to face the challenges rising from the foreseen alternation of phases of classical mission operations and phases of autonomous operations of the satellite. Concluding the thesis, the final software product's features and capabilities are verified against the previously defined requirements and thus the overall success of the project is determined to be a 100% success fulfilling all primary project objectives. Finally, several fields for further research on the topic in general and work on the MPT itself are identified and outlined to pave the way for follow-up projects. / SONATE

Estados Unidos es el lugar de origen del jazz, se puede decir que esto es geográficamente cierto, mas no culturalmente, ya que se debe tener en cuenta que dicho género se formó con músicos negros en un contexto de segregación racial bien radical, agregando también a los migrantes latinos que aportaron parte de su cultura para la música de la época. El objetivo de este estudio es darle el valor que se merece a las verdaderas raíces del jazz, la influencia afrocaribeña. Con este fin, la pregunta de investigación es la siguiente: ¿Cuáles y cómo fueron las influencias afrocaribeñas en las propuesta musicales de jazz de 1940 a 1965? La pregunta de investigación se responde a través del análisis cultural, histórico y musical de diversos géneros musicales que serían las bases para crear el jazz, además, también se tendrá en cuenta el latin jazz, el cual vendría a ser la fusión de ritmos afrocaribeños con el jazz, pasando también por el auge del rock, el cual también está ligado a esta cuestión, para pasar finalmente a la salsa. Teniendo esto en cuenta, se llega a la conclusión que gran parte de la música occidental tuvo influencia afrocaribeña para el desarrollo de sus géneros musicales, tales como el jazz, el bugalú, el rock & roll, y el rock. Ya que lo afrocaribeño se ha apoyado bastante en la tradición oral, se podrían realizar investigaciones adicionales en los que incluyan testimonios de las personas involucradas en los desarrollos de dichos géneros. / The United States is the place of origin of jazz, it can be said that this is geographically true, but not culturally, since it must be taken into account that this genre was formed with black musicians in a context of very radical racial segregation, also adding to Latino migrants who contributed part of their culture to the music of the time. The objective of this study is to give the value it deserves to the true roots of jazz, the Afro-Caribbean influence. To this end, the research question is the following: What and how were the Afro-Caribbean influences on jazz musical proposals from 1940 to 1965? The research question is answered through the cultural, historical and musical analysis of various musical genres that would be the basis for creating jazz, in addition, Latin jazz will also be taken into account, which would come to be the fusion of Afro-Caribbean rhythms with jazz, also going through the rise of rock, which is also linked to this issue, to finally move on to salsa. Taking this into account, it is concluded that much of Western music had Afro-Caribbean influence for the development of its musical genres, such as jazz, boogaloo, rock & roll, and rock. Since Afro-Caribbean has relied heavily on oral tradition, additional research could be carried out that includes testimonies from the people involved in the development of these genres. / Trabajo de investigación

Las empresas pequeñas y medianas de construcción en la actualidad enfrentan un mercado de mucha competencia interna y externa, además de ello no cuentan con una metodología de control de sus costos por falta de conocimiento o interés. Por tanto, la introducción de metodologías y técnicas para gestionar sus proyectos es muy significativa, lo que mejorará su competitividad y rentabilidad, y así mantenerse en la industria de la construcción. Para el control de costos, tenemos a la técnica del Valor ganado EV, que representa una buena práctica de la gestión de proyectos, por lo que la Guía del PMBOK® 6ta Edición, lo establece como una herramienta de gestión, a usar para controlar y monitorear un proyecto. Con este fin en el presente trabajo se centró en el desarrollo de una metodología de aplicación de la técnica del valor ganado, en un proyecto de Saneamiento, aplicándose los procesos de planificación, ejecución y monitoreo y control del Valor Ganado, tomando en cuenta que la integración del alcance, tiempo y costo de un proyecto viene a ser la parte más importante al momento de planificar los trabajos, lo que nos resulta una línea base de medición de desempeño del proyecto (PMB) debidamente determinada para controlar y gestionar el desempeño del proyecto. De la aplicación de la metodología de la técnica del valor ganado EV, se resume que se puede obtener los datos necesarios para poder corregir o mejorar el desempeño de un proyecto. A pesar de que el indicador SPI, tiene una desventaja de control en la fase final del proyecto, y para superar ello, se complementará con la técnica del cronograma ganado. Con los resultados concluimos que adoptar los procedimientos plasmados no requiere de grandes modificaciones a las estructuras y políticas de organización que existe en una empresa. / Nowadays smalls and mediums enterprise (SME) of construction have a highly global competitive. In addition, they do not have methodologies of budget control, for lack knowledge or interest. So, introduction of methodologies and techniques for management your projects are much significate, getting better competitive and profit-earning capacity, and stay in the construction industry. For the costs control, we have technique of Earned Value (EV), represents a practice good in the project’s management, so that a Guide to the Project Management Body of Knowledge (PMBOK® guide) 6ta Edition, define as tool management to monitoring and controlled a project. The objective the present work is development an application methodology of earned value for a project construction water drinking and sewerage service. Where the application of process planning, executing, monitoring and controlling of earned value, emphasizing with much important, the integration of scope, schedule and cost of project, establishing as result the performance measurement baseline (PMB) approved to manage and control project performance. The methodology application of Earned Value EV technique, in summary that can getting data necessary to improve or correct the performance in a project. Even though that the indicator SPI, have a disadvantage, this has disadvantages in the phases project end, and to overcome it, complement with earned schedule technique. With the results, conclude the procedures adopt not need big changes in the politics and structures organization of enterprise. / Trabajo de investigación
