In this paper, a multiple trench split-gate silicon-on-insulator (SOI) lateral double-diffused MOSFET with a Schottky rectifier (MTS-SG-LDMOS) is proposed and its characteristics are studied using 2-D simulations. The new structure features double oxide trenches, a floating polysilicon split-gate, and a Schottky rectifier. Each oxide trench includes a vertical field plate which enhances the depletion...
In the wireless sensor actuator network (WSAN), in order to make the sensor nodes (S) and the actuator nodes (A) work together more efficiently and obtain more accurate assignment information of actuators, a novel data fusion model of actuators assignment were constructed. In this paper, the weights and thresholds of BP neural network (BPNN) were optimized by genetic algorithm (GA), and the GA-BPNN...
A novel exemplar-based image inpainting algorithm is proposed for solving the deficiencies of the classical Criminisi method, such as the error repair accumulation, high time complexity caused by the unreasonable design of the patch priority, inaccuracy criterion and its global search strategy. Thus, we construct a local structure measurement function by introducing the structure tensor theory, and...
BP neural network is an important and efficient method in machine learning. But there are some drawbacks lying in its local minimum and slow convergence speed. To solve these problems and enhance the performance of BP network, an optimized BP neural network by genetic algorithm is proposed in this paper. Firstly, we design a fitness function based on genetic algorithm for the view of obtaining the...
GIS soft and hydrological model are not always accessible to decision-maker and the public. In order to make GIS-based hydrological model accessible and improve the efficiency of the management of the watershed, a system integrated with web and distributed hydrological model is design and developed in this paper. Our Web-ESSI system is implemented using C# as programming language over an ArcGIS Server...
This paper propose a genetic based fuzzy logic controller to regulate the speed of separately excited DC motor. The fuzzy membership function and rules are optimized based on genetic algorithm. The DC motor speed control system is modeled and simulated in MATLAB/SIMULINK. Simulation results show that the optimized fuzzy logic controller not only has no overshoot, minimum settling times and vibrations,...
As an innovative product in foreign financial market, weather derivatives provide new ways for risk managing and transference. Its pricing is a core problem in researches. This paper applies the Ornstein-Uhlenbeck model, combining by time series assumption to simulate the variance of weather process, estimates the parameters using Shanghai's temperature data of years 1951–2009. Then the accuracy of...
This paper considers a Markov risk model in which the claim rates and sizes fluctuate according to the state of the risk business. When the surplus process is below zero, the insurer could borrow money at a debit interest rate to pay claims. Meanwhile, the insurer will repay debt from her premium income. A integro-differential equation satisfied by absolute ruin probability is derived. Finally, an...
Based on statistical concepts, Power Balance (PWB) method is used to estimate the magnitude of electromagnetic energy in electronic system under high-frequency interference. Its effectiveness has been preliminarily confirmed, while its flexibility and convenience are attractive features. In this paper, the generalization of network formulation based on PWB method is presented in details which makes...
Recently, the Enterprises in Network Society Community developed rapidly and competed intensely. In order to prevent emergence reverse evolution of the network society communities, this study give some advices on the Synergetic Evolution between the Enterprises in Network Society Community. Through the comparison with the Traditional enterprise, the enterprises in Network Society Community have their...
An amount of methods used in route planning (RP) for aircraft have emerged during the last few years. It is difficult to master these methods and make a fast choice to use among them, which results from the lack of domain knowledge representation and reuse of RP. To achieve the domain knowledge reuse and efficient planning process, an ontology defined by Web ontology language (OWL) for RP dubbed ONTRP...
When fatal forest disasters take place, only one retrieval depot usually can not provide enough supplies to resolve the emergency. So the problem about how to combine multi-depot-multi-resource has been put forward. The main objective of the multi-resource scheduling is how to achieve the least emergency time and the fewest retrieval depots. In this scheduling algorithm, there are mainly two factors...
