Suspension is one of the important parts of automobile which has a great influence on the comfort of riding, the stability of handling and the control of vehicle's posture. With the simple two degree of freedom of a quarter of the simplified model of automotive suspension, we use the fixed-gain control and the adaptive control to design the controller. Making use of the MATLAB simulation, the scientific...
Microplasmas have attracted more and more attention due to their unique characteristics, and breakdown voltage is an important parameter for microplasma devices, particularly for addressable arrays of microplasma devices. However, small changes in shape or interface would bring obvious change in breakdown voltage. In this paper, five groups of simulations of breakdown voltage were operated under different...
Edge enhancement is a key part of image processing in order to sharpen the edge and optimize the visual quality of the input image. This paper proposes novel edge-directed enhancement spatial phase filters based on the generalized radial Hilbert transform theory. The simulated results showed that the proposed spatial phase filters are more efficient and flexible for edge-directed enhancement than...
Audio classification is based on audio features. The choice of audio features can reflect important audio classification features in time and frequency time. The extraction and analysis of audio features are the base and important of audio classification. The most important problem is to extract audio features effectively and make them mutual independence to reduce information redundancy. In this...
Methods previously for K-nearest neighbors searching usually inefficient face millions of points. We propose two efficient K-nearest neighbors searching algorithms for unorganized cloud points: parameter adjustable single axes searching algorithm and algorithm based on Morton-code of cloud points. The first algorithm uses direct way to search K-nearest neighbors in 3D space. It sorts points by x,...
