In order to improve the thrust characteristics of the moving-magnet type linear permanent magnet brushless DC motor (LPMBLDCM), the structural characteristics and magnetic field are analyzed. The influence rule of electrical parameters and structural parameters on the electromagnetic properties and thrust performance are researched by finite element analysis (FEA). The effect regularity of structural parameters to mover velocity and thrust are researched as well as the electrical parameters. The LPMBLDCM system are established, and some relevant tests were taken to verify the correctness of simulation results. Simulation and experimental results show that the thrust and velocity of mover are affected by some key parameter. The results will surely provide the reference and guidance for the optimization of electromagnetic and thrust characteristics of LPMBLDCM.

Abstract Dynamic Route Guidance System, which can provide the drivers with the optimal routes, is one of the most efficient solutions to the traffic jam. This paper presents a bee inspired zonal vehicle routing algorithm to provide a reasonable and effective optimal route for the Dynamic Route Guidance System. Firstly, the proposed algorithm divided the whole traffic network into different traffic guidance zone based on Shapley value game. Then, real time traffic data was collected in each traffic guidance zone by inter-vehicle and vehicle-to-infrastructure communications. Ultimately, the proposal simulated the bee foraging phenomenon in the biological system to synchronously compute the optimal routes in each traffic guidance zone. The simulation results show that the algorithm

Sparsity was prior condition in compressed sensing which had been widely concerned in signal reconstruction. Meanwhile nonsubsampled contourlet proposed as a development to contourlet, not only provided flexible multi-scale, multi-direction sparse image decomposition but also featured with shift-invariance property which was beneficial to image denoising. This paper combined threshold operator in nonsubsampled contourlet domain with non local means filter for image denoising in the compressed sensing framework. Therefore, NSCT-NLmeans based compressed sensing reconstruction was proposed for noisy image. The experiment results showed that NSCT- NLmeans based algorithm outperformed the other multi-resolution and multi-directional transforms in recovering and denoising image simultaneously.

The main purpose of this work is to find a suitable solution for improving the efficiency of the Software Project Management (SPM). In this work we have used a novel artificial intelligence method, a fuzzy logic approach to evaluate the SPM efficiency. There are many IT organization suffers on managing the SPM, it may be due to several reasons such as project work can’t begin on time, it may have vague requirements, people involved in the project can’t stay within project parameters, unity among the people involved in the projects and improper communication unclear project objectives and goals. All these issues usually may lead to delay in the project and have greater impact on the project failure, which in turn causes the poor Software Project Management efficiency.Fuzzy logic is one of the Artificial Intelligence method helps to solve the problems when there is a SPM with uncertainty and vagueness in it. We used the fuzzy inference system (FIS) to quantify the SPM efficiency under uncertainty and vagueness of the parameters involved in quantifying SPM efficiency. The outcome of the work is really appreciable and encouraging to quantify the Software Project Management efficiency

There is the magnetic coupling among control windings of controllable reactor of transformer type (CRT), the decoupling integrated magnetic technology is applied to the structure design of CRT in this paper. To realize the decoupling among the control windings we propose a magnetic integrated structure of CRT by providing low magnetic resistance magnetic circuit for control windings magnetic flux. The winding leakages of this structure are calculated, its inductance-transformer equivalent circuit is also established, and the equation of the coupling degree of control windings and no-load current with the lateral column air gap size are deduced. The simulation model for a CRT is fabricated with MATLAB/SIMULINK. Simulation and analysis results shows that when increasing the air gap, the magnetic coupling between the control windings decreases apparently, the utilization ratio of windings current is also raised. The simulation results verify the effectiveness of this method by controlling the lateral column air gap size to achieve the purpose of decoupling.

For the purpose of anti-jamming communications, the radiation pattern reconfiguration of plasma antenna excited by surface wave were studied. The self-consistent model used to describe the relation between the pump signal and radiation pattern is put forward by combining the Boltzmann Equation and Maxwell Equation. And the correctness of the model is validated by using FDTD approach. The experiment system that used to measure the radiation pattern is established to validate the correctness of the self-consistent model. The investigation results show that the radiation pattern are reconfigurable by controlling the pump signal.

Due to the thermal error modeling of CNC machine tools has characters of small sample and discrete data, the variable-weight combined modeling method was presented by integrating time series analysis and least squares support vector machines. Taking minimum sum of error square of prediction model as the optimization criterion, optimal weights in different time were calculated. Using grey GM (1, 1) model to predict the variable weights, the prediction result of thermal error was obtained as well. Application of the grey variable-weight combined model on a five axis vertical machining center indicated that it can get higher prediction accuracy than single modeling method. Therefore online error compensation to CNC machine tool becomes more effective.

In order to determine the human physical condition according to the conventional tested data quickly and accurately, in this paper we proposed a trend selection based scalable parallelizable induction of decision trees algorithm (TESTSPRINT), based on the concept of pure interval and trend selection method. Based on the basic test data such as height, weight and grip strength, we can create a human physical condition decision tree quickly; according to the decision tree we can determine human physical health status quickly. Theoretic analysis and experimental demonstrations show that the algorithms this paper proposed outperforms existing algorithms in time and space complexity, and it was proved fruitful applications in the decision human physical health status with high accuracy.
