Towards Manageable Mobile Agent (2008)
Paulo Simões, Paulo Marques, Luis Silva, João Silva, O Boavida
Abstract. This paper addresses the problem of managing distributed mobile agent infrastructures. First, the weaknesses of current mobile agent implementations will be discussed and identified from...
Genus and braid index associated to sequences of renormalizable Lorenz maps (2008)
We describe the Lorenz links generated by renormalizable Lorenz maps with reducible kneading invariant $(K_f^-,K_f^+)=(X,Y)*(S,W)$, in terms of the links corresponding to each factor. This gives one...
ROBUST AND ADAPTIVE MODELING OF SOFTWARE AGING (2008)
Artur Andrzejak, Luis Silva, Dep Engenharia Informática
The wide-spread phenomenon of software (image) aging is known to cause performance degradation, transient failures or even crashes of applications. This undesired behavior is especially visible in...
Dynamic Deployment of Services on Mobile Agents Systems (2007)
Nuno Santos, Paulo Marques, Luis Silva
Abstract. Mobile agents are a very interesting paradigm for structuring distributed applications. By using them, distributed applications can implement part of their functionality as a set of...

Project no. FP6-00426 Using Micro-Reboots to Improve Software Rejuvenation (2007)
In Apache Tomcat, Paulo Silva, Luis Silva, Artur Andrzejak, In Apache Tomcat, Paulo Silva, ...
As software complexity increases so does the difficulty in solving all software defects before the production stage, even with advanced software testing tools. Those software defects are often the...
Deterministic models of software aging and optimal rejuvenation schedules (2007)
Artur Andrzejak, Artur Andrzejak, Luis Silva, Luis Silva, Coregrid Tr
Automated modeling of software aging processes is a prerequisite for cost-effective usage of adaptive software rejuvenation as a self-healing technique. We consider the problem of such automated...

Abstract Background Low back pain and its associated incapacitating effects constitute an important healthcare and socioeconomic problem, as well as being one of the main causes of disability among...
Jorge Duarte, Luís Silva, J. Sousa Ramos
One of the interesting complex behaviors in many cell membranes is bursting, in which a rapid oscillatory state alternates with phases of relative quiescence. Although there is an elegant...
Sébastien Tixeuil, Sébastien Tixeuil, William Hoarau, William Hoarau, Luis Silva, Luis Silva, ...
In this paper we review several existing tools for fault injection and dependability benchmarking in grids. We emphasis on the FAIL-FCI fault-injection software that has been developed in INRIA Grand...

Artur Andrzejak, Artur Andrzejak, Patricio Domingues, Patricio Domingues, Luis Silva, Luis Silva, ...
Availability of resources in desktop grids is characterized by high dynamicity, a consequence of the local (owner) control policies in such systems. The efficient usage of desktop computers can...
A Framework for Smart Proxies and Interceptors in RMI (2002)
Nuno Santos, Paulo Marques, Luis Silva
Abstract. The Java Remote Method Invocation (RMI) API shields the developer from the details of distributed programming, allowing him to concentrate on application specific code. But to perform some...
On the Design of Eilean: A Linda-like Library for MPI (1994)
João Carreira, Luis Silva, João Gabriel Silva, Jo��o Gabriel Silva
In this paper, we introduce the design of a parallel library for MPI based on the Linda programming paradigm, called Eilean. It provides a scalable distribution of the Tuple Space through an...
