In space based robotics, one of the most important problems is the disturbance to the satellite attitude and to the satellite microgravity environment caused by satellite mounted robot operation. This paper reports on computer-aided motion planning strategies to overcome this problem. Point to point motion designs are generated which not only connect prescribed start and end points of the robot...

Computer-Aided Inspection Planning (CAIP) has been a research topic for the past 25 years. Most of the CAIP systems were developed for Coordinate Measuring Machines (CMMs). The authors reviewed these CAIP systems and categorized them into two groups: tolerance-driven and geometry-based CAIP systems. Compared with CMMs, On-Machine Inspection (OMI) systems provide direct inspection in manufacturi...

For proper management of life cycle of machines and manufacturing facilities, it is important to perform appropriate maintenance operations, and to keep machine status for better reuse and recycling opportunity. For this purpose, a virtual maintenance system is very effective, where facility life cycle model is constructed in computer, and reliability and availability of machines are predicted ...

In general, deep drawing products have various cross-section shapes such as cylindrical, rectangular and nonaxisymmetric shapes. The application of the surface area calculation to non-axisymmetric deep drawing process has not been published yet. In this research, a surface area calculation for non-axisymmetric deep drawing products with elliptical shape was constructed for a design of blank sha...

We have designed and implemented a prototype system to aid in the surgical repair of congenital aural atresia. A two-level segmentation algorithm was first developed to separate tissues of similar intensity or low tissue contrast. Then an interactive visualization modular was built to display the labeled tissues. The system allows a 3-stage interactive planning in which positioning, marking and...

eBusiness and egovernment initiatives have resulted in tremendous economic development, improvements in quality of life, and operational efficiencies around the globe. However, 50-80% of these initiatives fail in developing countries and also in the underserved sectors of the developed countries (e.g., local governments and small to medium businesses) due to re-invention of the wheel. This docu...
