In order to automate the human visual inspection process in the diode production factories, we construct an experimental computer system with an image digitizing circuit and a microscope. Based on the statistical decision theory, we formulate six mathematical functions for the six major defects frequently seen on diode pellets. On one thousand good samples(More)
We propose a multiprocessor architecture with partially shared memory blocks, which is, we think, best suited for the successive approximation of scientific computing problems, such as matrix operations, partial differential equations etc. The topology is a ring. But the system configuration is a subset of an orthogonal multiprocessor Scherson and Hwang(More)
In this paper, we specify the performance of our pioneering billiard robot in pulling game training. We discuss the important role of practical demonstration in sports education, and introduce the robot technology to teaching demonstration of sports item. And put forward our algorithm for the fast image calculation of the ball obstructed by other balls, the(More)
We propose a database system which consists of a personal computer, disks and a pipeline of microcomputers. The rela tional join is a target. We find that there exist two different algorithms: one contributes the speed up of the pipeline cycle time, and the other reduces the number of the necessary disk accesses. The controller watches the state of the(More)
