This paper presents an investigation of three communication schemes which may be used in a distributed robotic system, two based on implicit forms of communication (mechanical interaction and vision) and one on an explicit form of communication (infrared s ...
Boosting-based methods have recently led to the state-of-the-art face detection systems. In these systems, weak classifiers to be boosted are based on simple, local, Haar-like features. However, it can be empirically observed that in later stages of the bo ...
When we achiev a good performance of the field-oriented vector control system, it is necessary to detect the speed and flux of the motor. Usually it is hard to implemment these sensors. Then the sensor-less contro-system techniques using the observer inste ...
Databases are an important part of today's IT infrastructure: both companies and state institutions rely on database systems to store most of their important data. As we are more and more dependent on database systems, securing this key facility is now a p ...
Dynamic power management (DPM) is a design methodology for dynamically reconfiguring systems to provide the requested services and performance levels with a minimum number of active components or a minimum load on such components. DPM encompasses a set of ...

In this paper, we examine the causes and effects of contentionfor shared data access in parallel programs running on a software distributed shared memory (DSM) system. Specifically, we experiment on two widely-used, pagebased protocols, Princeton’s home-ba ...
We address two issues in Evolutionary Robotics, namely the genetic encoding and the performance criterion, also known as fitness function. For the first aspect, we suggest to encode mechanisms for parameter self-organization, instead of the parameters them ...
Wavelet or sub–band coding has been quite successful in compression applications, and this success can be attributed in part to the good approximation properties of wavelets. In this paper, we revisit rate–distortion (RD) bounds for the wavelet approximati ...
Articulatory representations are expected to bring better speech recognition results. This requires to estimate the parameters of a speech production model from the speech sound, problem known as acoustico-articulatory inversion. Known methods to solve thi ...
We consider the problem of multicast routing in a large single domain network with a very large number of multicast groups with small number of receivers. Such a case occurs, for example, when multicast addresses are statically allocated to mobile hosts, a ...
