The scope of this paper is to compare a one year performance of three grid-connected PV module technologies systems, installed at the Faculty of Sciences Semlalia Marrakech (latitude 31.6497°N and longitude 8.0169°W). The studied silicon-based PV modules technologies are monocrystalline (mono-c-Si), amorphous silicon (a-Si) and polycrystalline (poly-c-Si). Monthly and annual evaluated performance...
Complicated processes of through-silicon-via fabrication makes low yield of through-silicon-via mass production. Through-silicon-via redundancy is one of various ways that have been put forward to improve reliability of electrical interconnections. Allocation of through-silicon-vias is changed as redundant through-silicon-vias are added. Consequently, thermal dissipation and thermal mechanical reliability...
Experiments by Ratnam et al.[1] demonstrate the benefit of drift eye movements for the discrimination of a diffraction-limited tumbling E sized near the sampling limit of the cone photoreceptor array. Subjects perform better at discriminating the orientation of the E when its projection moves on the retina with the same motion statistics as drift eye movements, but not necessarily correlated to the...
This paper presents results for numerical analysis of three electrostatic problems by using four MoM (method of moments) formulations while exploiting the rotational symmetry of the analyzed structures. These results are mutually compared, but also compared to the results obtained by the electrostatic solver where rotational symmetry is not considered. It is observed that exploiting the rotational...
Distribution plays an increasingly important function in delivering value to the consumer. Therefore, organizations need to adopt a holistic view of the entire network. These needs have propelled the modeling of Supply Chain Network Design (SCND) and this study investigates that from the Retail Supply Chain's perspective. The study reports the model formulation of the SCND optimization after carrying...
This article presents the implementation of an indoor localization approach that combines map matching and a circular particle filter defined in a Bayesian framework. The technique relies only on velocity and heading observations coupled with a map of the road network. No prior knowledge of the initial position is given. A circular distribution is used to match the vehicle's heading with the roads...
Aiming at nonlinear degradation data in step-stress accelerated degradation test (SSADT), the reliability assessment method is put forward based on Wiener process. the process and degradation data model of SSADT is analyzed. The time scale model is used to convert nonlinear data into linear data. Draft coefficient of Wiener process is regarded as a random variable. Reliability model for nonlinear...
This paper gives high efficiency silicon-silicon dioxide (Si-SiO2) and silicon-silicon nitride (Si-Si3N4)) grating SOI structure, which may be used as optical interconnects in optical communication system. Both the absorption, reflection and diffraction losses are included to compute overall transmitted efficiency. Simulation results reveal that the reflectance is zero at the wavelength of 1 μm for...
The new generation of spectrometers with high energy resolution can resolve elastic peaks of electrons reflected by atoms in solids. In this regard, there is an increasing interest in the applications of the so-called Elastic Peak Electron Spectroscopy (EPES) for measuring composition-versus-depth profiles since it is non-destructive and sensible to the presence of hydrogen in solids. This study presents...
This paper presents a study of the electrostatically actuated circular micro-plates used in MEMS ultrasonic flow meter. In this paper, a distributed model has been used to investigate the pull-in instability and frequency response of circular plate subjected to nonlinear distributed electrostatic force. A variational formulation based on Hamilton's principle is used to obtain the nonlinear governing...

In-silico modeling is an important part of biomedical engineering. Advanced controllers providing high quality control can be validated through it checking if the available mathematical model of the given biomedical process produces the desired output. However, due to high patient variability the advanced linear control methods applied on linearized models could produce several distortions compared...

This paper proposes a Higher Order Sliding Mode (HOSM) based control algorithm for air intake circuit of diesel engine. The current diesel engine is a complex system that has mechanisms like Variable Geometry Turbo charger (VGT), Exhaust Gas Recirculation (EGR) to limit the amount of exhaust emissions. Since both VGT and EGR flows are driven by the exhaust gases, there is a strong coupling between...
The paper deals with human-computer interaction in which the cooperation leads to solve a difficult issue of discrete optimization. Considered jobs scheduling problem in a robotic cell consisting of two machines and a robotic operator. Only one of two machines can work at a time and there are setup times between successive operations on a machine. The goal is to determine a schedule — permutation...
The nonlinear interaction of strong millimeter electromagnetic waves with silicon integrated p-i-n-structures placed in a metallic waveguide is investigated theoretically. The nonlinear equation added by proper boundary conditions has been formulated and solved numerically. An influence of the strong electromagnetic wave results in the excess injection of carriers into the semiconductor i-region between...
High efficiency is among the most important targets in power electronic converters. A possible approach to obtain this goal is the usage of better switches.

Traditional bus-based systems-on-chip (SoCs) are turned to on-chip networks (NoCs) to overcome communication bottleneck. But, fabricating such NoC-based systems without any defect in interconnects or logics is a major challenge. This paper proposes a cost effective and scalable on-line test solution that detects and diagnoses intra-and inter-shorts in NoC interconnects. The proposed solution offers...
As the dimensions of electronic devices, especially transistors, are getting smaller and smaller, novel modeling approaches must be developed to reveal the physics and predict the performance of not-yet-fabricated ultra-scaled components. In this paper the basic requirements to simulate nanoscale devices are first reviewed before introducing a hierarchical quantum transport approach going from empirical...
Impurities being present in a semiconductor in high concentrations may form agglomerates. Agglomeration usually demobilizes the impurities and, in case of dopants, also renders them electrically inactive. A standard approach in continuum process simulation assumes the formation of energetically favorable small clusters of size m. High numbers of m are used to mimic an often desired saturation of the...
