Advancement of micro-joining methods has become an essential prerequisite in the manufacture of micro devices at ever smaller scales. For complex environments, micro joints must possess comprehensive mechanical quality and stability. Micro resistance spot welding has thus been identified as a promising technology in industrial applications. In this study, multi-objective optimization during welding...
We consider an application of sparse optimization in the error concealment area. State-of-the-art spatial and temporal error concealment method is improved and compared. By solving for limited numbers of significant predictors using the sparse optimization, our algorithm performs subjectively and objective better for the concealed result.
For the characteristics of supply chains in the enterprises, it raises the evaluation factors in the partner selection in the mining enterprises, and constructs multi-objective optimization model of partner selection in mining enterprises, combined with the degree of the close relationship between business. And then, it introduces the application of genetic algorithm in partner selections of the mining...
An image-reject hairpin bandpass filter used in Ku-band low noise block (LNB) is designed, and optimized in the paper. The designed detail of the filter is explained and the image-reject is illustrated theoretically. According to the research, under the condition of reducing the size as small as possible, the hairpin filter used in Ku-band LNB we designed not only can satisfy the demands from bandwidth...
