Well, don't let the menu icon misguide you, the aim was to convey research interests and "skills" icon was all I could find :-)
RESEARCH INTERESTS

RESEARCH PROJECTS
− C-Mobile (http://c-mobile.ptinovacao.pt/)
The strategic objective of C-MOBILE is to foster the evolution of the mobile broadcast business by providing enhancements to the 3GPP MBMS for systems beyond 3G.
It will address both resource efficiency and service flexibility, by close coupling of broadcast and communication capabilities on all layers, covering the radio access, core network and the service enablers, across multiple technologies, providing a smooth migration for MBMS evolution, which will be in line with the vision of a federated global multicast broadcast transport as well as emerging beyond 3G standards.
Within the radio access network it will propose new radio interface technologies, radio resource management and new topological approaches in the architecture for an efficient support of enhanced MBMS services allowing a commercially attractive implementation.
C-MOBILE will help to understand how best to organise and schedule MBMS content from the BM-SC through the core network, radio access, to the end users. Since this is multimedia content, interactions with the 3GPP IP Multimedia Subsystem are expected and C-MOBILE will explicitly investigate how best MBMS can make use of capabilities provided by the IMS. The current concept of group communication is narrow within Release 6 MBMS specification. C-MOBILE will research, investigate and define ways to use multicast technology to support personalized services and in particular the concept of multicast content community where users also contribute to the multicast service. Key market and business requirements for multicast-broadcast services will be identified to aid defining research directions, leading also to new business models involving the various players. To that end it is critical to understand the needs of multicast-broadcast users, network operators, and content providers.
The project intends to make important contributions to the standardisation bodies and to prove experimentally or via system level simulations innovative concepts.
− Grid Enabled Interactive and Distributed Analysis on Handheld Devices
The project aimed at development of a Grid-enabled environment for interactive physics analysis on handheld devices. JClarens (JClarens a Java-based supplement to the Python-based Clarens Web Services Framework developed at the California Institute of Technology) is used to interface the handhelds with the Grid, which allows applications on the handheld devices to search for data files, perform analysis, and display results as 2D and 3D visualizations.
JASOnPDA and WiredOnPDA are the main application developed for PocketPC devices. JASOnPDA is the PocketPC version of Java Analysis Studio (JAS) which was developed at Stanford Linear Accelerator (SLAC). JASOnPDA enables visualization of ROOT files on PocketPC devices. WiredOnPDA is the PocketPC version of WWW Interactive Remote Event Display (WIRED), a joint venture of Stanford Linear Accelerator (SLAC) and European Organization for Nuclear Research (CERN). WiredOnPDA can display and analyze events stored in HepRep2 files.
In addition, a prototype was developed that enabled PDA and mobile phone users to launch CPU-intensive jobs on a Grid, get back status information, and retrieve outputs. At the same time, the server-side Grid was designed as a self-healing, high availability distributed system, to simulate the behavior of the Grid as it will be in a few years time.
