This paper presents a template-based vision system to detect and classify the nonuniformaties that appear on the semiconductor wafer surfaces. Design goals include detection of flaws and correlation of defect features based on semiconductor industry expert’s knowledge. The die pattern is generated and kept as the reference beforehand from the experts in the semiconductor industry. The system is...

This paper takes the large band sawing machine GB42500H as the research object, and establishes the dynamics models of its various parts. Respectively, the relative research is done from the theoretical modal analysis and the dynamic performance testing. According to the analysis results, the structure or geometry improvement scheme of the parts is proposed. The paper also studies preliminarily...

This paper derives the long-run marginal timber and sawing cost of producing lumber from a dual linear programming framework. A computational accounting procedure is suggested and compared with a recently designed procedure in industrial use. To be useful, the calculated cost figures should be approximately constant over a nontrivial interval of sales volumes. The preliminary results of a case ...
