Trabajo De Fin De Carrera TRABAJO DE FIN DE CARRERA TÍTULO DEL TFC: VirtualEPSC, el mundo virtual 2.0 del Campus del Baix Llobregat TITULACIÓN: Ingeniería Técnica de Telecomunicación, especialidad en Telemática AUTORES: Luis Miguel Amorós Martínez Noemí Arbós Linio DIRECTOR: Toni Oller Arcas FECHA: 14 de julio de 2010 Título: VirtualEPSC, el mundo virtual 2.0 del Campus del Baix Llobregat Autores: Luis Miguel Amorós Martínez Noemí Arbós Linio Director: Toni Oller Arcas Fecha: 14 de julio de 2010 Resumen En las últimas décadas, se han producido cambios tecnológicos de gran envergadura que han provocado una ruptura brusca con las tecnologías existentes hasta el momento. Una de las más importantes es Internet, que se ha convertido en el entorno de comunicación más importante de la historia, con más de mil millones de usuarios en todo el mundo. Internet ha sufrido una serie de cambios en los últimos años y uno de los últimos conceptos que han surgido es el de web 2.0. Esta filosofía se basa en dar un rol más activo a los usuarios, por ejemplo, utilizando la colaboración de los usuarios en Internet, también llamado inteligencia colectiva; y en el diseño centrado en el usuario. Este trabajo describe los pasos seguidos para desarrollar una web 2.0 que aloja un mundo virtual que emula el Campus del Baix Llobregat. Se describe cómo son el diseño y la arquitectura del proyecto, y cómo se ha hecho la implementación de las diferentes partes. El resultado se denomina VirtualEPSC, una web 2.0 que aloja una aplicación multimedia en 2D que emula el Campus del Baix Llobregat, donde los usuarios podrán interactuar entre ellos. Esta plataforma permite promocionar el campus de una manera divertida y que las personas que quieran conocerlo puedan visitarlo de una manera virtual. Además, en la aplicación se ofrecen servicios relacionados con el campus y se proporciona la posibilidad de que usuarios registrados puedan crear sus propias zonas dentro del mundo virtual, incentivando aún más la participación de los usuarios. Title: VirtualEPSC, the virtual world 2.0 of Campus del Baix Llobregat Authors: Luis Miguel Amorós Martínez Noemí Arbós Linio Director: Toni Oller Arcas Date: July, 14th 2010 Overview In last decades there have been big technological changes which have caused a sharp break with existing technologies so far. One of the most important is Internet which has become the most important communications environment in history, with over one thousand millions of users worldwide. Internet has undergone several changes in recent years. One of the new concepts that have arisen is Web 2.0. This philosophy is based on giving a more active role to the users, for example, using the collaboration of Internet users, also called collective intelligence; and the user-centered design. This project describes the steps followed to develop a web 2.0 that provide a virtual world which emulates the Campus of the Baix Llobregat. It is described how the design and architecture is, and how the implementation to the different parts has done. The result is called VirtualEPSC, a web 2.0 hosting a multimedia application in 2D that emulates the Campus of the Baix Llobregat and where users will be able to interact to each other. This platform allows promoting the campus in a funny way and people who want to know how the campus looks like can visit it in a virtual way. In addition, the application offers some services related to the campus and provides the possibility for registered users to create their own areas inside the virtual world, encouraging the participations of users.

  • Pragmatic Version Control Using Subversion
    What readers are saying about Pragmatic Version Control using Subversion I expected a lot, but you surprised me with even more. Hav- ing used CVS for years I hesitated to try Subversion until now, although I knew it would solve many of the shortcom- ings of CVS. After reading your book, my excuses to stay with CVS disappeared. Oh, and coming from the Pragmatic Bookshelf this book is fun to read too. Thanks Mike. Steffen Gemkow Managing Director, ObjectFab GmbH I’m a long-time user of CVS and I’ve been skeptical of Sub- version, wondering if it would ever be “ready for prime time.” Until now. Thanks to Mike Mason for writing a clear, con- cise, gentle introduction to this new tool. After reading this book, I’m actually excited about the possibilities for version control that Subversion brings to the table. David Rupp Senior Software Engineer, Great-West Life & Annuity This was exactly the Subversion book I was waiting for. As a long-time Perforce and CVS user and administrator, and in my role as an agile tools coach, I wanted a compact book that told me just what I needed to know. This is it. Within a couple of hours I was up and running against remote Subversion servers, and setting up my own local servers too. Mike uses a lot of command-line examples to guide the reader, and as a Windows user I was worried at first. My fears were unfounded though—Mike’s examples were so clear that I think I’ll stick to using the command line from now on! I thoroughly recommend this book to anyone getting started using or administering Subversion.

    Release Notes for Cisco Policy Suite for Release 7.0 First Published: September 26, 2014 Last Updated: July 10, 2015 Release: 7.0 Contents This document describes the new features, feature versions and limitations for the Cisco Policy Suite software. Use this document in combination with documents listed in the “Related Documentation” section on page 33. This document includes the following sections: • Introduction, page 1 • New and Changed Information, page 2 • Installation Notes, page 9 • Limitations and Restrictions, page 15 • Caveats, page 23 • Related Documentation, page 33 Introduction The Cisco Policy Suite is a comprehensive policy, charging, and subscriber data management solution that allows service providers to control and monetize their networks and to profit from personalized services. The Cisco Policy Suite has the following components: • Policy Server (PS) • Charging Server (CS) • Application Gateway (AGW) Cisco Systems, Inc. www.cisco.com New and Changed Information • Unified Subscriber Manager (USuM) • Subscriber Analytics The Cisco Policy Suite provides an intelligent control plane solution, including southbound interfaces to various policy control enforcement functions (PCEFs) in the network, and northbound interfaces to OSS/BSS and subscriber applications, IMSs, and web applications. The Cisco Policy Suite modules are enabled individually or deployed as an integrated end-to-end policy, charging, and service creation solution. Competitive Benefits The new Cisco Policy Suite solution provides these benefits over competitive solutions. • Cisco Policy Suite architecture allows simultaneous sessions and transactions per second (TPS) capacity to be independently scaled. This allows Cisco Policy Suite to be efficiently sized for both high simultaneous sessions with low TPS or low sessions with high TPS, resulting in lower total cost of ownership when compared to traditional PCRF models.

  • Design Options of Store-Oriented Software Ecosystems: an Investigation of Business Decisions ∗
    Design Options of Store-Oriented Software Ecosystems: An Investigation of Business Decisions ∗ Bahar Jazayeri1, Olaf Zimmermann2, Gregor Engels1, Jochen K¨uster3, Dennis Kundisch1, Daniel Szopinski1 1 Paderborn University, Germany fbahar.jazayeri,gregor.engels,dennis.kundisch,[email protected] 2 University of Applied Sciences of Eastern Switzerland, Switzerland [email protected] 3 Bielefeld University of Applied Sciences, Germany [email protected] Abstract. Nowadays companies like Apple create ecosystems of third- party providers and users around their software platforms. Often online stores like Apple App Store are created to directly market third-party solutions. We call such ecosystems store-oriented software ecosystems. While the architecture of these ecosystems is mainly derived from busi- ness decisions of their owners, ecosystems with greatly different archi- tectural designs have been created. This diversity makes it challenging for future ecosystem providers to understand which architectural design is suitable to fulfill certain business decisions. In turn, opening a plat- form becomes risky while endangering intellectual property or scarifying quality of services. In this paper, we identify three main design options of store-oriented software ecosystems by classifying existing ecosystems based on similarities in their business decisions. We elaborate on the design options, discuss their main contributions, and provide exemplary ecosystems. Our work provides aspiring ecosystem providers with the reusable knowledge of existing ecosystems and helps them to take more informed architectural decisions and reduce risks in future. Keywords: Software ecosystems, Reusable designs, Variabilities 1 Introduction Software ecosystems have become an emerging architectural approach for many companies to grow. The term software ecosystem is inspired from ecological ecosystems that are the result of an interplay between organisms as well as interactions with a physical environment [1].
