Depending on the fact that knowledge can be learned by oneself, which is different from epidemic spreading, we take into account self-learning mechanism in the knowledge transfer process. In this paper, we propose a knowledge transfer model, and derive the mean-field equations that describe the dynamics of the knowledge transfer in homogeneous networks. Using differential theory, we obtain the knowledge...
We developed a Multi-Subband Ensemble Monte Carlo simulator for non-planar devices, taking into account two-dimensional quantum confinement. It couples self-consistently the solution of the 3D Poisson equation, the 2D Schrödinger equation, and the 1D Boltzmann transport equation with the Ensemble Monte Carlo method. This simulator was employed to study MOS devices based on ultra-scaled Gate-All-Around...
This paper describes comparison of thermal properties between Si power MOSFET and SiC power MOSFET. Conventionally, Si power MOSFET has been widely used in power electronics area. On the other hand, SiC power MOSFET has wide band gap, and is gaining attention as a new generation power device. However, thermal properties of SiC power MOSFET has not been clear. For appropriate thermal management of...
This paper presents the scope of applicability of Dual-Phase-Lag model in modern electronic structures. Moreover, the investigation of obligatory application of this model, instead of the classical approach based on Fourier-Kirchhoff model, to heat transfer modeling is included. Furthermore, the modified Fourier-Kirchhoff thermal model, containing the special time lag parameter, is also taken into...
As a relatively mature field, scientific computing has the opportunity to lead other software fields by leveraging its solid, existing knowledge base.Our position is that by following a rational design process, with the right tool support, desirable software qualities such as traceability, verifiability, and reproducibility, can be achieved for scientific software.We have begun development of a framework,...
In statistics, the concept of a concomitant, also called the induced order statistic, arises when one sorts the members of a random sample according to corresponding values of another random sample. Indeed, multivariate order statistics induced by the ordering of linear combinations of the components arises naturally in many instances. As a contribution, we provide a general second-order statistical...
Many-core processors exhibit hundreds to thousands of cores, which can execute lots of multi-threaded tasks in parallel. Restrictive power dissipation capacity of a many-core prevents all its executing tasks from operating at their peak performance together. Furthermore, the ability of a task to exploit part of the power budget allocated to it depends upon its current execution phase. This mandates...
We construct a two-echelon supply chain with one supplier and two retailers. Revenue sharing contract and lateral transshipment are considered in the discussed supply chain. We present a game model, and study how lateral transshipment under revenue sharing contract affects retailers' inventory choices and supply chain profit. Retailers choose their inventory levels by considering the possibility of...
In this paper, we review and prove certain properties regarding t-way coverage when covering arrays are merged together to form larger arrays. Moreover, we build upon these theoretical observations to formulate a procedure on how, from the input space model of a composed SUT and t-way test suites for its components, to create a larger and unified t-way test suite. The proposed modelling methodologies...
Recent interests in exploring the potential of renewable energy possibilities and readiness in sultanate of Oman has showed that it can engage renewable energy technologies, such as solar, wind power and various hybrid power models to mitigate fossil fuel limitations, revitalize additional economic development, create new jobs and preserve a cleaner environment. However, limited knowledge and information...
This paper presents the results of a comparison of the well-established power-flow algorithms Gauss-Seidel, Newton-Raphson, Dishonest Newton-Raphson, Decoupled Load Flow, Fast Decoupled Load Flow, DC Power-Flow and the new Holomorphic Embedding Load Flow Method (HELM). The algorithms are assessed using 21 PQ-powerflow test cases with numbers of nodes ranging from 2 to 3120. The focus of the analysis...
The objective of the proposed system is to develop an adaptive iterative linear regression (ILR) based clustering for wireless sensor network. ILR classifies the initial cluster simultaneously in horizontal and vertical patterns to form two sub clusters. Among these two, the best is selected based on similarity index (SI). This selected cluster is taken as reference and the iteration continues until...
This paper deals with the reduction of the ADM1 using the “state-variable association” method, to calibrate a simple model of microalgae anaerobic digestion (the MAD model). In simulation, we show that the behavior of the calibrated MAD model and of the ADM1 are identical. Using experimental data, the calibrated MAD model predicts well the real behavior of the digestion of a substrate composed of...
The emergence of three dimensional (3D) interconnects has reduced wire floor planning problems, increased device density, reduced RC wire delay, and minimized the energy dissipated by the long planar wires. Vertical 3D interconnect refers to a conductive filled through silicon vias (TSVs), which electrically connects front and back side of a silicon layer. Few electrical models and characterizations...
Due to the non-linearity of current-voltage of solar cell model, the conventional methods are incapable to extract the parameters of solar cell with high accuracy. The implicit nonlinear equation describing the single and double diodes solar cell in five and seven parameters is rewritten as optimization problems with constraint functions and it is solved by using a firefly algorithm optimization....
Integrated semiconductor devices with improved endurance to external conditions simulation methods using TCAD Synopsys were analyzed. Such effects as self-heating in lateral high voltage SOI-MOSFET, breakdown in low-voltage SOI n-MOSFET, charge trapping in oxides during SOI MOFSET irradiation and bipolar current gain calculation features were considered. Model features with the greatest impact on...
A thin-film tandem solar cell is designed from two different semiconductors in order to observe the impact of thickness of active layers on External Quantum Efficiency (EQE) by keeping the anode voltage fixed for both top and bottom cells. A nearly lattice matched ZnO-Si hetero-structure thin film device has been simulated to get the maximum EQE at a particular wave length. For the anode voltage of...
Sequential composition is a supervisory control architecture for addressing control problems in complex dynamical systems. Although sequential composition works properly for a single system, it is not designed for cooperative systems. This paper extends the standard sequential composition by introducing a novel approach to compose multiple sequential composition controllers towards cooperative control...

The corresponding variables are obtained by RFM model, Kano model and BG/NBD model. The customer segmentation model provides ten groups of customers with corresponding marketing strategies,...
A new algorithm of diagnosis strategy based on fault mode criticality is proposed, aiming at the lack of consideration to possible damage to the equipment in fault diagnosis and negative impact of test sequence in existing algorithms. The proposed algorithm is mainly composed of heuristic function based on fault mode criticality and optimal single-step search strategy. The optimal tests are selected...
