We propose a compact model for undoped short-channel nanoscale cylindrical-gate MOSFETs. The drain-current model is written in terms of the mobile charge density. This latter is calculated through the solutions of the ...

This thesis addresses the use of dynamic neural networks in the spectral estimation problem. The first phase of our contribution is used to estimate the line spectrum of a signal modeled by the sum of a set of complex ...

Laser sources are the most important elements in a channel of optical telecommunications. However these are unstable, and have fluctuations. To overcome this drawback it is necessary to place an optical isolator in the ...

The work in this thesis is a development of a QRS detector working on large amplitudes. A nonlinear whitening and optimized adaptive filter based on an RBF neural network whose activation functions are sigmoidal is used ...

This thesis is devoted to the study of thin films silicon oxynitride SiOxNy characteristics. Currently, silicon oxynitride SiOxNy is considered the most appropriate material for the manufacture of electronic and optoelectronic ...

The aim of this thesis work consists in the improvement of ZnO’s structural, electrical and optical properties for humidity analysis. The preparation of undoped ZnO thin films doped ZnO with Aluminium and Mercury and codoped ...

"Ultrasound images are corrupted by a multiplicative noise – the speckle –, which makes hard high-level image analysis. In order to solve the difficulty of designing a filter for an effective speckle removing, we propose ...

The simulation can play an important role in all phases of the development of communication systems, from the earliest step of design, to the final steps of realization, testing and implementation of the system. Our thesis ...
