There are about 6,098 million wireless devices in the world and there were 117. 7 million smartphone users in 2012. The number is increasing day by day. With the attractiveness of web services for mobile devices, the concern of security for mobile devices has been brought up. There is a need for organizations to allow employees to use smartphones for their(More)
In this paper, viewer and converter softwares are presented for smart machining process using an industrial robot. The viewers for NC, CLS, DXF and STL files illustrate their surface representation with normal direction vectors. For example, the DXF is a data format developed by Autodesk to realize data interoperability among different makers’ CAD systems.(More)
We have proposed to use vector quantization (VQ) for compressing a decision making rule (a policy) on a multi-dimensional memory array. Our VQ method can reduce the amount of memory for recording a policy. In this paper, we compare this method with other techniques that economize the amount of memory in order to measure the ability of this method more(More)
The authors presented a machining system based on an industrial robot for foamed polystyrene materials. The developed robotic CAM system provided a simple interface without using any robot languages between operators and the machining robot. In this paper, a robotic preprocessor is reviewed for the machining robot to convert STL data into cutter location(More)
