Recent trend in reducing the size of products has given Micro Electrical Discharge Machining (MEDM) a significant amount of research attention. Due to the high precision, low tolerance and good surface quality that it can deliver, MEDM is potentially an important process for fabrication of micro-tools, micro-components and parts with micro-features. This paper briefs and highlights the various ...

In Plan9 most resources are provided as files, including regular on disk stored files. When the set of files grow, it is important to be able to quickly locate files based on their contents. This paper describes the set of tools documented in tags(1), which provides file indexing and content based searching for Plan 9, using a file system to provide the search interface.

The balance of safety and wellbeing of the public is disturbed by an emergency situation. Emergency responders try to mitigate this danger and restore the balance of public welfare and security during an emergency. This act is termed as emergency response. These emergencies could occur at a national level and hence they can be large and complex which could necessitate in the cooperation of seve...

Studies examining friendships among Mexican-American adolescents have largely focused on their potentially negative influence. The current study examined the extent to which deviant and achievement-oriented friend affiliations are associated with Mexican-American adolescents' school adjustment and also tested whether support from friends and parents moderates these associations. High school stu...

In Structure from Motion algorithms, the error in the estimated motion aaects each reconstructed 3D point in a systematic way. This paper attempts to isolate the eeect of the motion error (as correlations in the structure error) and shows theoretically that these correlations can improve existing multi{frame Structure from Motion techniques. Finally it is shown that new experimental results and...

This paper briefly reviews sources of symmetry in planning and highlights one source that has not previously been tackled: plan permutation symmetry. Symmetries can be a significant problem for efficiency of planning systems, as has been previously observed in the treatment of other forms of symmetry in planning problems. We examine how plan permutation symmetries can be eliminated and present ...

701 The ability to obtain three-dimensional structure from visual motion is important for survival of human and non-human primates. Using a parallel processing model, the current work explores how the biological visual system might solve this problem and how the neurophysiologist might go about understanding the solution.
