In this thesis, we address the problem of spectrum-sharing for wireless communication where multiple users attempt to access a common spectrum resource under mutual...

In this thesis, we consider the problem of reliable data packets transmission using single-carrier signaling over frequency-selective fading channels. Our objective is...

The main target of the thesis was to study the thermal integration of a magnesium hydride (MgH2) tank with an external heat source. At first, the evolution of material...

This thesis deals with biological membranes, studied from the point of view of theoretical physics. We focus on some generic effects of the presence of one or two...

Percutaneous valve implantation (PVI) is a new with fast growing expansion procedure. Nevertheless, this promising technic has some reefs. Impairment of the implanted...

Two-dimensional images and three-dimensional volumes have become a staple ingredient of our artistic, cultural, and scientific appetite. Images capture and immortalize...

Software systems are moving toward highly dynamic and heterogeneous environments. This dynamism is derived by several factors: the massive arrival of embedded devices...

The work in this thesis deals with metamaterials, its components and applications. A historical overview about these materials, features and researches in the domain...

In this thesis, solutions for the design of robust Active Vibration Control (AVC) systems are presented. The thesis report is composed of two parts. In the first one,...

Along with the increasing need of construction land, numerous soil reinforcement technologies are proposed in order to improve the soil mechanical properties on one...

This thesis is dedicated to the resources allocation for the transmission of scalable multimedia data under Quality-of-Service (QoS) constraints on heterogeneous...

Components-Off-The-Shelf (COTS) are used for rapid and cost effective developmentof software systems. It is important to test the correct functioning of COTS in new...

One of the most prominent issues in the design and implementation of OFDMA based systems is the need for a very fine frequency synchronization due to the fact that...

We consider in this thesis the resource allocation problems in multi-user OFDM downlink systems under various Quality of service (QoS) constraints. Our goal is to...

Despite the effort made to define methods for the design of high quality software, experience shows that failures of IT systems due to software errors remain very...

Objectives : reporting the design, development and experiments of a new robotic system for prostate brachytherapy including prostate tracking and MRI to Ultrasound...

Electronic cooling in Superconductor - Insulator - Normal metal (S-I-N) junction is based on the energy selectivity of electron tunneling induced by the superconductor...

In the introductory chapter we first give the major results about entanglement and open quantum systems. In particular we give the proof of entanglement sudden death...

4He and 3He are model systems for understanding quantum properties of strongly interacting matter. For this reason many studies have been devoted for the understanding...

Ubiquitous Information Systems appeared as a consequence to emerging and evolving communication and mobile technologies providing the system with information on its...
