Motion detection aims at discriminating between moving objects and a static environment. This task can be seen as the grouping of local motion observations into moving...

In this thesis we present new approaches in the domains of soft fault detection and location in complex wire networks, based on the properties of time reversal. When...

A Multiple-Input Multiple Output (MIMO) radar can be broadly defined as a radar system employing multiple transmit waveforms and having the ability to jointly process...

This thesis intends to build an original process of spectral analysis of stationary signals. Its originality lies in the decision concept that we used. It is not based...

Enterohemorrhagic Escherichia coli (EHEC) are an important subset of Shiga toxin–producing E. coli (STEC) associated with foodborne infections. These bacteria can...

Achieving accurate, cost-efficient, and fast anomaly localization is a highly desired feature in computer networks. A necessary and sufficient condition on the set of...

Recognizing familiar faces rapidly seems crucial in everyday life. The actual speed at which a familiar face can be recognized remains however unknown. The current...

This is an overview of the main physical ideas for application of field effect transistors for generation and detection of Terahertz radiation. Resonant frequencies of...

Future cognitive radio networks are expected to come as a disruptive technological advance in the currently saturated field of wireless communications. The idea behind...

This manuscript is dedicated to the detection and caracterization of interest points for 3D meshes. First of all, we show the limitations of the curvature measure on...

This study is a preliminary study to use a fonctionnalized microsensor based on electromechanical detection of biological species present at trace levels. Two aspects...

To avoid the underwater mine threat and to limit human interventions, navies use autonomous underwater vehicles. An underwater mine warfare mission is divided into...

In this work, the performance of InP-based HEMTs as a THz detector was experimentally studied. The nature of the THz rectification by the two-dimensional plasmons in...

To take relevant decisions, autonomous systems have to continuously estimate their environment via embedded sensors. In the case of 'intelligent' vehicles, the...
