The SEA simulation method to reduce car interior noise in high frequency is introduced by the properties modification of door glass. An SEA (Statistical Energy Analysis) model of a domestic car was built. The inputs of interior noise were got by the roads testing and other simulations. The accuracy of this model was validated by the comparison results of testing and software. The following simulation...
In order to suppress undesirable noises in triangular meshes for quality improvement, an effective smoothing method based on curvature flow is proposed in this paper. For triangular meshes generated from planar contours, the continuity information amongst adjacent contours is utilized to determine whether a vertex represents a geometric feature to preserve or an isolated noise to smooth. Before smoothing...
In this paper, we propose a novel technique of using cross validation (CV) data sampling to construct an ensemble of acoustic models for conversational speech recognition. We further propose using hierarchical Gaussian mixture model (HGMM) and repartition training data to increase the ensemble size and diversity. The proposed methods are found to work well together for ensemble acoustic modeling....
It is difficult to make optimal process planning for polishing product because of the complex processes and the multi-criteria, attributes and vagueness of process parameters. To solve this problem, this paper combines the methodologies of case based reasoning (CBR) and fuzzy set theory (FST) to support process planners in planning processes and making decisions effectively for polishing product....
With the rapid development of GPU (Graphics Processor Unit) in recent years, GPGPU (General-Purpose computation on GPU) has become an important technique in scientific research. However GPU might well be seen more as a cooperator than a rival to CPU. Therefore, we focus on exploiting the power of CPU and GPU in solving generic problems based on collaborative and heterogeneous computing environment...
We present an improved texture synthesis algorithm over arbitrary surfaces in this paper. The algorithm adopt the searching strategy of restriction degree to compute the texture coordinates of each triangular patch. It reduces the restrictive conditions as searching for the best matching patches and debases the complexity of the algorithm at the same time. Then aiming at the local boundary unmatching...
