In this thesis, we consider the problem of source localization in large sensor networks, when the number of antennas of the network and the number of samples of the...

Many real-world problems are dynamic, i.e. their objective function (or cost function) changes over time. The main approach used in the literature is to adapt static...

Health-care organizations are facing new challenges such as the aging population, the rise of health care costs and the rapid progress of medical technologies. New...

The objective of this thesis is to study the evolution of scalar field carried by a flow from a temporal image sequence. The estimation of the velocity field of...

The development of a model for crowd movement simulating the evacuation of public spaces becomes useful and necessary to determine the effectiveness of transportation...

The main objective of the thesis was to identify experimentally the mechanical and rheological behavior of granular media in an environment varying in complexity. In...

In order to comply with the standards governing the discharge of industrial effluents (Water Framework Directive, target date 2021) concerning micropollutants, in...

Security is a key aspect in information systems (IS) development. One cannot build a bank IS without security in mind. In medical IS, security is one of the most...

The intermetallic based on rare earth and transition metal compounds present interesting magnetic properties for the technological applications (permanent magnets,...

This dissertation examines how migrants mobilize ethnicity throughout the different stages of their migratory journey. The study is based upon multi-sited ethnographic...

In this thesis we investigate numerical methods for the homogenization of materials the structures of which, at fine scales, are characterized by random...

In this PhD thesis I propose coprocessors architectures for high performance computations of asymmetric primitives like RSA, Elliptic Curves and Pairing. Coprocessors...

This research focused on concentration of traces in a sample using electropreconcentration in a fluidic device containing a nanoslit. The technique was discoverd a few...

Structures can be submitted to severe loadings, especially impacts and earthquakes, and reducing the seismic vulnerability of existing structures is thus an important...
