Heat related processing can have various effects on food and food ingredients. Besides the intended effects to improve safety and quality of the products, undesired changes, nutritional or toxicological, can also occur. In this area, acrylamide formation occupies an important role, as this molecule has been considered as a potential cause of cancer. The possibility that this molecule may be ...

The eight-band k.p model of strained zincblende crystals has been extensively used to describe the electronic structure of III-V semiconductor nanostructures.in the present work, we propose to extend these approaches in order to provide a fast and easy method to evaluate the electronic spectra of narrow-gap semiconductor Quantum Dots.A complete 2D axi-symmetric model is proposed for the ...

In this paper, we investigate random doping fluctuation effects in Trigate SOI MOSFETs by solving the 3D Poisson, Drift-diffusion and Continuity equations numerically.The presence of a single doping impurity atom induces a threshold voltage (VTH) shift in the transistor. The threshold shift depends on the polarity and the physical location of the impurity atom. Our results show that the typical ...

In advanced semiconductor devices, most of the reliability issues in interconnects occur at a local scale. More precisely, the voiding phenomenon in copper lines is one of the key issues. Hence, a better understanding of the mechanisms governing electromigration would enable the development of more accurate predictive models.A model of vacancy migration is proposed. The thermal, stress and ...

A microwave plasma simulation has been tested, and will be fitted and validated. Two types of assumptions were compared: in the first approach the plasma density depends directly on the electric field and some characteristic values of it; in the second approach, plasma density and temperature conservation equations are solved.The second approach was used for Nitrogen plasma. In the case of SF6 ...

The purpose of this work is to understand and model the electromagnetic field inside a microwave reactor, in order to study the interaction between the reactor and plasma discharge. The first goal of this study is to characterize the antenna / plasma coupling. The electric field interacts with the plasma discharge via a set of input parameters: the permittivity and the conductivity related to ...

An eigenvalue as well as a harmonic response analysis is performed on the Gullfaks C, Knock Out Drum (KOD) including some of the connecting pipe systems. The vibration behavior of two new choke valves and their specific connection to the KOD are of special interest. The main concern is the low frequency induced vibration as a consequence of the platform movements. A frequency band between 0-20 Hz ...

Cardiac muscle exists in two forms: the contractile myocardium and specialized conducting cells that spread the wave of depolarization throughout the chambers of the heart. Action potentials are initiated in the sinoatrial (SA) node, which serve as the “pacemaker” of the heart. In this presentation, this is investigated thoroughly with different examples and simulated results of ...

Since the nineties many works have been dedicated to splat formation modeling. The main part of these works takes into account the molten droplet impact onto a flat surface, its flattening and solidification.The aim of this work is to test if a simplified model in 2D allows to characterize the real contact between the splat and the substrate and to compare the results of the experiments and the ...
