Actualment, i amb la ràpida expansió en el món educatiu de les plataformes d'aprenentatge virtual, s'experimenta una demanda de funcionalitats que puguen ser usades des d'aquestes plataformes i que donen resposta als reptes educatius dins d'aquest nou paradigma d'aprenentatge.En aquest treball s'ha fet una tasca d'integració d'eines que possibiliten la creació, modificació, visualització i magatzematge de mapes conceptuals dins d'una plataforma d'aprenentatge molt usada actualment, tant en ensenyament secundari com universitari. La plataforma moodle.L'eina per construir mapes conceptuals triada ha segut l'anomenada VUE, desenvolupada en la universitat de Tufts.Ambdues eines moodle i VUE s'han desenvolupat amb codi obert i baix llicències de programari lliure, així es poden tindre tots els avantatges que aquestes llicències proporcionen.El resultat és una integració que possibilita la utilització de mapes conceptuals dins de la plataforma moodle.

El principal objectiu d'aquest projecte és l'estudi de la tecnologia ViWiFi tant des del punt de vista de la seva base tècnica com de les seves possibles aplicacions actuals i futures, especialment referent a la integració de serveis addicionals com la missatgeria instantània. Una vegada analitzats els conceptes teòrics es realitza un estudi de les principals eines de codi obert que permeten implementar aquest tipus de plataformes, per a finalment concloure amb la instal·lació pràctica d'una plataforma de laboratori.

L'empresa Desenvolupaments Intel·ligents es dedica a la creació del software financer i borsari. Tot el sistema informàtic esta basat en màquines amb plataformes Microsoft Windows. S'ha decidit implementar un nou sistema informàtic basat en GNU/Linux. Aquest és l'objecte d'aquest treball. El nou sistema informàtic basat en GNU/Linux ha de incloure tots els equips clients (que seran els ordinadors nous) i els servidors (es reaprofitaran els ordinadors antics) cobrint tots els serveis que abans donava el servidors antics mitjançant aquest sistema operatiu i software lliure.

Engineering of negotiation model allows to develop effective heuristic for business intelligence. Digital ecosystems demand open negotiation models. To define in advance effective heuristics is not compliant with the requirement of openness. The new challenge is to develop business intelligence in advance exploiting an adaptive approach. The idea is to learn business strategy once new negotiation model rise in the e-market arena. In this paper we present how recommendation technology may be deployed in an open negotiation environment where the interaction protocol models are not known in advance. The solution we propose is delivered as part of the ONE Platform, open source software that implements a fully distributed open environment for business negotiation

The system described herein represents the first example of a recommender system in digital ecosystems where agents negotiate services on behalf of small companies. The small companies compete not only with price or quality, but with a wider service-by-service composition by subcontracting with other companies. The final result of these offerings depends on negotiations at the scale of millions of small companies. This scale requires new platforms for supporting digital business ecosystems, as well as related services like open-id, trust management, monitors and recommenders. This is done in the Open Negotiation Environment (ONE), which is an open-source platform that allows agents, on behalf of small companies, to negotiate and use the ecosystem services, and enables the development of new agent technologies. The methods and tools of cyber engineering are necessary to build up Open Negotiation Environments that are stable, a basic condition for predictable business and reliable business environments. Aiming to build stable digital business ecosystems by means of improved collective intelligence, we introduce a model of negotiation style dynamics from the point of view of computational ecology. This model inspires an ecosystem monitor as well as a novel negotiation style recommender. The ecosystem monitor provides hints to the negotiation style recommender to achieve greater stability of an open negotiation environment in a digital business ecosystem. The greater stability provides the small companies with higher predictability, and therefore better business results. The negotiation style recommender is implemented with a simulated annealing algorithm at a constant temperature, and its impact is shown by applying it to a real case of an open negotiation environment populated by Italian companies

En el presente proyecto se ha abordado la tarea de acercar las tecnologías existentes de plataformas de gestión de infraestructuras ofrecidas en la nube (Cloud Management Platform, aka CMP) al mundo empresarial. En concreto, se ha desplegado una solución de explotación de infraestructuras privadas en la nube (IaaS) enfocada a la gestión de un datacenter virtualizado, utilizando para ello soluciones completamente basadas en software libre, en concreto, OpenNebula.

The Universitat Oberta de Catalunya (Open University of Catalonia, UOC) is an online university that makes extensive use of information and communication technologies to provide education. Ever since its establishment in 1995, the UOC has developed and tested methodologies and technological support services to meet the educational challenges posed by its student community and its teaching and management staff. The know-how it has acquired in doing so is the basis on which it has created the Open Apps platform, which is designed to provide access to open source technical applications, information on successful learning and teaching experiences, resources and other solutions, all in a single environment. Open Apps is an open, online catalogue, the content of which is available to all students for learning purposes, all IT professionals for downloading and all teachers for reusing.To contribute to the transfer of knowledge, experience and technology, each of the platform¿s apps comes with full documentation, plus information on cases in which it has been used and related tools. It is hoped that such transfer will lead to the growth of an external partner network, and that this, in turn, will result in improvements to the applications and teaching/learning practices, and in greater scope for collaboration.Open Apps is a strategic project that has arisen from the UOC's commitment to the open access movement and to giving knowledge and technology back to society, as well as its firm belief that sustainability depends on communities of interest.

This is a project to develop a document for teaching graduate econometrics that is "open source", specifically, licensed as GNU GPL. That is, anyone can access the document in editable form, and can modify it, as long as they make their modifications available. This allows for personalization, as well as a simple way to make contributions and error corrections. The hope is that people preparing to teach econometrics for the first time might find it useful, and eventually be motivated to contribute back to the project. The central document is something between a set of lecture notes and a text book. It's not as terse as lecture notes, but not as complete or well-referenced as a text book. Of course, the document is constantly evolving, and you are welcome to modify it as you like. The document contains (at least when viewed in HTML or PDF form) hyperlinks to example programs written using the GNU/Octave language. The document itself is written using the LyX word processor. LyX documents can be exported as LaTeX, so the system is quite portable.
