With the development of the newly proposed cloud computing, an increasing number of software systems are deployed in the cloud environment. Both researchers and engineers in academia and industry focus on seeking efficient virtual machine (VM) deployment and VM consolidation strategies. Increasing the utilization of physical or virtual resources which are directly providing services is mainly concerned,...
Compared to scanning by hand, traditional robotic scanning to measure or to inject EM near field has advantages and disadvantages. It can scan large area with excellent resolution. However, it is difficult to program the experience of engineers into the robotic system for selecting scan areas, and complex shaped objects are nearly impossible to scan automatically. A CMM (Coordinate Measuring Machine)...
Fuzzy measure is a kind of set function which can represent the interaction of IF-THEN rules in reasoning, and fuzzy integral is decision tool in information fusion and process control problem. Although the fuzzy cognitive map model is an effective approach in reason process and the intuitionistic fuzzy cognitive map model introduces intuitionistic fuzzy set which uses the hesitancy as the indeterminacy...
To solve the shortcomings of low cutting accuracy and curling edges of the traditional slitter. So the paper raised a tension control system without sensor on the basis of analysing process of the slitter. It realized the flexible adjustment of the cutting parameters. The materials went in and out of cutting rolls used servo motor constitutional main-secondary pulling mode. By controlling the difference...
In view of the difficulty in adjusting the quantization factor and scale factor in the traditional fuzzy PID control, the paper proposes an improved fuzzy PID control method based on particle swarm optimization (PSO) searching algorithm, which optimizes the quantization factor and scale factor in the fuzzy PID controller, and improves the searching ability of PSO by using rebound strategy, to make...
Biological systems exhibit remarkable adaptation and robustness in the face of widely changing environments. Currently speaking, we often imitate the properties of biological systems. Based on this thought, it also exists the analogous situation in the WSNs (wireless sensor networks). Survivability is the ability to provide essential services in the presence of attacks and failures, and recover full...
The thermodynamics of exhaust gas recirculation (EGR) coolers plays a very important role for reducing oxides of nitrogen (NOX) emissions of diesel engines. Using the ANSYS software, some fluid thermodynamic models of EGR coolers were established by using the finite element method (FEM); and the temperature fields of gas fluids in the EGR coolers were simulated and verified by comparing the experimental...
In natural languages, compound words play an important role and their automatically extraction is very helpful in information retrieval, information extraction and text classification. We introduce a semi-supervised Chinese compound extraction approach based on HMM using bootstrapping in this paper. First, we define a set of tags BEMI {beginning, end, middle, independence}, which means the position...
3-D specific face model construction by way of 2-D face image is an active topic in 3-D face modeling research. In this paper, stereoscopic sense of vision is used to reconstruct 3-D feature points. Then multi-layer and multi-region RBF (radial basis function) based on feature points of frontal and profile face image is adopted for reconstructing the generic face model to get 3-D specific face model...
