Given a bounded open subset Ω of R d and two positive weight functions f and g, the Cheeger sets of Ω are the subdomains C of finite perimeter of Ω that maximize the ratio C f (x) dx ∂ * C g(x) dH d−1. Existence of Cheeger sets is a well-known fact. Uniqueness is a more delicate issue and is not true in general (although it holds when Ω is convex and f ≡ g… (More)

Based on recent advances in control theory, we propose the notion of jitter margin for periodic control tasks. The jitter margin is defined as a function of the amount of constant delay in the control loop, and it describes how much additional time-varying delay can be tolerated before the loop goes unstable. Combined with scheduling theory, the jitter… (More)

A virtual laboratory is a computing system that allows to share the physical resources available in a laboratory with remote users connected on the internet. This paper describes a particular virtual laboratory environment for running real-time robot control experiments over the internet through a standard web browser. Using the proposed approach, a remote… (More)

We consider an optimization problem in a given region Q where an agent has to decide the price p(x) of a product for every x ∈ Q. The customers know the pricing pattern p and may shop at any place y, paying the cost p(y) and additionally a transportation cost c(x, y) for a given transportation cost function c. We will study two models: the first one where… (More)

The term " control theory " refers to the body of results-theoretical, numerical and algorithmic-which have been developed to influence the evolution of the state of a given system in order to meet a prescribed performance criterion. Systems of interest to control theory may be of very different natures. Features 7 Self-contained: the book can be used by… (More)

Presents a hierarchical computer architecture specifically designed for controlling a multisensory robot system. In a flexible and modular fashion. The approach used for the implementation of the system is botton-up, in the sense that high level processes are developed from elementary sensory-motor activities, carried out at lower levels of a hierarchical… (More)

Given the probability measure ν over the given region Ω ⊂ R n , we consider the optimal location of a set Σ composed by n points Ω in order to minimize the average distance Σ → R Ω dist (x, Σ) dν (the classical optimal facility location problem). The paper compares two strategies to find optimal configurations: the long-term one which consists in placing… (More)

This report describes the work carried out within the research project " Merging Real-Time and Control Theory for Improving the Performance of Embedded Control Systems " during the spring of 2004. The overall objective of the work has been to develop integrated control and scheduling methods for improving the performance of real-time control systems with… (More)
