Presentation of "Analysis for Linear Systems based on Reachability Sets"
Silvestre, Daniel; Rosa, Paulo; Hespanha, João; Silvestre, CarlosThe problem of deciding which inputs in a model influence the most the state or output is often of practical importance, especially in the cases in which the system can be over-parameterized. In this context, a designer is required to perform sensitivity analyses so as to select which inputs are the most relevant to the problem at hand and remove those with smaller or no impact. In this paper, we tackle this is...

Desynchronization for Decentralized Medium Access Control based on Gauss-Seidel...
Silvestre, Daniel; Hespanha, João; Silvestre, CarlosWe address the Desynchronization problem of achieving an equally spaced transmission schedule in a cooperative fashion. This problem arises in a shared medium communication and is of importance to achieve a fair multiple access schedule at the Medium Access Control (MAC) layer in the context of Wireless Sensor Networks (WSNs). In this paper, we investigate the convergence rate of different optimization algorith...

Fault Detection for Cyber-Physical Systems: Smart Grid case
Silvestre, Daniel; Hespanha, João; Silvestre, CarlosThe problem of fault detection and isolation in cyber-physical systems is growing in importance following the trend to have an ubiquitous presence of sensors and actuators with network capabilities in power networks and other areas. In this context, attacks to power systems or other vital components providing basic needs might either present a serious threat or at least cost a lot of resources. In this paper, w...
A PageRank Algorithm based on Asynchronous Gauss-Seidel Iterations
Silvestre, Daniel; Hespanha, João; Silvestre, CarlosWe address the PageRank problem of associating a relative importance value to all web pages in the Internet so that a search engine can use them to sort which pages to show to the user. This precludes finding the eigenvector associated with a particular eigenvalue of the link matrix constructed from the topology graph of the web. In this paper, we investigate the potential benefits of addressing the problem as ...
