Aspheric surfaces were also generated on silicon and germanium. Grinding was done to give a good surface finish and at the same time focused on getting the maximum amount of ductile streaks. After grinding the surfaces were lapped and polished. The polishing curve is a saturation curve where rapid improvement in surface finish is obtained followed by a gradual decrease in the Ra, with the curve flattening out parallel to the horizontal time axis. It was found that the initial roughness after grinding was not the sole criterion for rapid polishing but rather the amount of ductile streaks. The amount of ductile streaks is not only dependant on the feed and the depth of cut but also on the grit size of the diamonds as well as its concentration, and not least of all on the type of bond. Brightness of silicon surfaces and lightness of glass workpieces and their relationship with roughness have been determined.","PeriodicalId":344984,"journal":{"name":"2002 IEEE International Conference on Industrial Technology, 2002.

This paper proposes a method to embed a watermark in the audio signal, which is robust against the MP3 compression, and the sound is maintained according to the human audio ability. Since MP3 is a lossy compression technique that crops the inaudible frequency ranges of signal, we can not embed the watermark in the inaudible signal ranges. In this method, we select the audible frequency ranges with small sound pressure level as watermark embedding frequency range. By this technique the embedded watermark is robust against MP3, and the human will not recognize the watermark data as noise. In addition, we try to utilize the color image as the watermark that is convenient to claim the ownership. We performed the experiments with the popular songs and the results are satisfied.","PeriodicalId":344984,"journal":{"name":"2002 IEEE International Conference on Industrial Technology, 2002.

The simulator is based on 3D representation and employing the inverse kinematics approach to derive the corresponding rotational and translation movement of the mechanism. The simulator makes it possible to analyze the accuracy of a 3D tool-path based on a prescribed set of the cutter location (CL) points as well as a set of the cutter contact (CC) points with tool inclination angle. The resulting trajectory of the tool is not unique and depends on the initial set up of the machine which in turn is problem dependent. Furthermore, the simulator can be used to simulate the milling process, verify the final cut and estimate the errors of the actual tool-path before the real workpiece is actually being tested with the real machine. Thus, reducing the cost of iterative trial and error. Tool path simulation is verified by a series of cutting experiments performed by means of the proposed software and evaluates the accuracy of milling. It has been shown that the proposed graphical 3D software presents an efficient interactive approach to the interactive modification of a tool path based on an appropriate set of transformations as well as to verification of the tool path optimization algorithms.","PeriodicalId":344984,"journal":{"name":"2002 IEEE International Conference on Industrial Technology, 2002.

Typically, the switched system consists of several subsystems switched according to a given switching law and can be widely seen in industries such as process control systems, temperature control systems and so on. From theoretical point of view, stability including switchings has been mainly analyzed and studied. Although various approaches for switched systems have been reported, few research about reachability with constraints has been reported. In this paper, we take a system in which inputs are constrained to a certain set, and study reachability for the system. Furthermore we propose a switching law based on partitioned states of the system and some computational algorithm for the switching law. Then the proposed method is applied to a simple numerical example.","PeriodicalId":344984,"journal":{"name":"2002 IEEE International Conference on Industrial Technology, 2002.
