This paper studies the Hall mobility of Hall structures integrated in two CMOS technological processes, regular bulk and Silicon on Insulator respectively. The main character of this study is the Basic Hall cell, for which accurate dimensions (length and width of the active region, electrical contacts size and area of the p-substrate) are given. To this purpose, three-dimensional physical models are...
The incomplete normal form game (INFG), in which there are some infeasible profiles, is considered. The structures of INFG and the dynamics of evolutionary INFG are investigated via semi-tensor product (STP) of matrices. First, the dynamics of evolutionary INFG is presented. Then a method is provided to verify whether an INFG is potential. Certain properties of potential INFGs are revealed. Finally,...
This paper deals with an actual topic concerning the diagnosis of Internet of Things (IoT) controlled flexible manufacturing systems (FMS). We focus on models realized with Markov chains of FMS with stochastic and not equal throughput rates. Discrete-event models assume that FMS is decomposed, and we study the following events: an Internet server fails, an Internet server is repaired, an Internet...
In this paper, we propose an approach to select top-k cloud services. Our approach combines the trust, determined by the reputation of the provider, and the QoS. We present different algorithms for processing such selection queries and evaluate them through a set of experiments.
The area of flexible electronics is rapidly expanding and evolving. With applications requiring high speed and performance, ultra-thin silicon-based electronics has shown its prominence. However, the change in device response upon bending is a major concern. In absence of suitable analytical and design tool friendly model, the behavior under bent condition is hard to predict. This poses challenges...
Many calibration algorithms for vector network analyzers using partially unknown standards can be stated as an eigenvalue problem. The construction of the eigenvalue problem is described and examples for line reflect match (LRM) and thru reflect line (TRL) calibrations are given. Advantages of the new algorithm are that all uncertainties can be taken into account and that it is fully analytic. A further...
Silicon double heterojunction (DH) solar cells represent a possible future path for high-efficiency, low-cost solar power. These cells forgo doped p-n and n+-n (or p+-p) homojunctions diffused at ∼900 °C in favor of < 200 °C-deposited selective heterojunction contacts, which block one type of carrier while allowing the other to pass freely[1]. One heterojunction injects minority carriers (blocking...
This paper describes the angular dependence of the nonparabolicity factor of the silicon band structure and the influence of the angular dependence on the density of states. In order to investigate the angular dependence of the nonparabolicity factor of the band structure, we calculate the silicon band structure using the first principle calculation. In order to investigate the influence of the angular...
We have proposed a distributed storage system which dynamically makes storage tiers and optimizes location of data blocks autonomously. This aims to enhance the I/O performance of the storage system without remarkable network overhead. Our system dynamically organizes storage tiers considering device characteristics. And the data blocks will be placed in a suitable storage tier according to their...
The proposed algorithm presents a solution to improve the grey wolf optimizer performance using weighted distance and immigration operation. The weight distance is used for the omega wolves movement is defined from fitness value of each leader (alpha, beta and delta). The traditional grey wolf algorithm has only one pack and has opportunity to trap in local optimum so the wolves in our proposed algorithm...
The objective of the project is to develop a model for the capacitive ultrasonic transducer described in the Ladabaum et al., [1] paper. The main element of the transducer is a metalized silicon nitride membrane suspended on a rigid support above a heavily doped silicon bulk. The cavity under the membrane is vacuumed. When a voltage is applied between the metalized membrane and the bulk, the Coulomb...
The security of code-based cryptography relies primarily on the hardness of generic decoding with linear codes. The best generic decoding algorithms are all improvements of an old algorithm due to Prange: they are known under the name of information set decoding techniques (ISD). A while ago a generic decoding algorithm which does not belong to this family was proposed: statistical decoding. It is...

The algorithm of the computer program which allow to calculate the spectral ratios in case of a different values of the diameter...
Exponential signal categories, usual in the orthodontic dynamics, are considered, damped aperiodic in relation to time and space. They are expressed through time and space constants. For predetermined conditions, expressed in final durations, final lengths and inflexion points, respectively, this paper presents a digital method for determining the structure parameters, by the resolution of two categories...
Size dependence of random telegraph noise (RTN) in ultra-narrow silicon nanowire transistors with width far less than 10nm is experimentally measured and statistically analyzed for the first time. Single-trap RTN amplitude shows nearly exponential distributions, which reaches 170mV at 1.8% quantile for the narrowest transistor. The origins of long tail distributions and strong size dependence are...
Thermo-mechanical stress accumulation in the power electronic integrated circuit (PIC) devices influences their lifetime and reliability. In order to determine both the temperature and the stress accumulation, numerical simulation is a very important tool in the design of PIC devices for quantifying and enhancing their lifetime and reliability. An open source solution integrated in Salome-Meca and...

The heterogeneous robots are driven to their centroid of multiplicatively-weighted Voronoi regions under the action of the proposed control law, the target position is modified in real-time based on the density distribution of the environment. Two types driving mechanisms are considered in this paper, different...
The growing complexity of todays technical systems demands for improved simulation techniques. One important aspect is the way how hierarchy of interconnected dynamical systems is handled. Focusing on this, some existing approaches are reviewed and a modified component connection modeling (CCM) framework is introduced. Furthermore, several conceptual considerations of CoSimMA, a modular simulator...
In this paper, a closed-form physics-based surface potential approach is proposed to derive a compact model for current in high-frequency and high-power LDMOS transistors. For this purpose, we have modeled the drift region with three variable resistors. Effects of velocity saturation in the channel as well as the quasi-saturation due to the existence of the N-Drift region have been taken into account...
In this paper, we introduce the possible texturing methods and their effects on the performance of multicrystalline silicon solar cells. A 2-D process and device simulator is used for this purpose and the resultant efficiency increase is studied. The optimized texturing angel is deducted by theoretical calculations of ray tracing. Theoretical calculations show that the best texturing angle to have...
