A parallel ray tracing library is presented for rendering high detail images of three dimensional geometry and computational fields. The library has been developed for use on distributed memory and shared memory parallel computers and can also run on sequential computers. Parallelism is achieved through the use of message passing and threads. It is shown(More)
As deep-sub-micron and beyond technology emerges, quality assurance of microelectronic circuits and systems becomes more important than ever. Consequentially, (1) a strong need for well-educated microelectronic circuits and systems test engineers is desired by the industry, (2) graduate-level research efforts are also called to overcome numerous(More)
A large number of our nation’s bridges must be replaced or are in need of major repair/rehabilitation because they do not conform to current demands due to deterioration caused by aging or environmental conditions, heavier vehicles and increased traffic volume. Since a replacement alternative usually involves high costs and/or substantial interference with(More)
Computer-aided test stations have been developed for research, experimentation, and testing of electric motors and generators. Data acquisition and control of the machines and drives are provided through a computer and its interfaces. Machines are connected to the computer through transducers for data acquisition, and power electronic drives for machine(More)
This paper describes our experience with using Mentor Graphics electronic design automation software and Xilinx field programmable gate arrays at the introductory level. The Department of Electrical Engineering at the University of Missouri Rolla has been a member of Mentor’s Higher Education Program for almost ten years. We have been successfully(More)
