    A study was carried out to determine which power system operating functions will benefit most from advanced graphics facilities, and which graphics facilities (visualization and interaction techniques from both existing and emerging graphics standards) offer the greatest potential benefits to the dispatcher. It was found that the power system operating functions that can benefit the most from advanced graphics facilities, in order of priority (high to low), are: system restoration, distribution system mapping, alarming, system monitoring and contingency analysis, economic applications, voltage profiling, and weather. Several examples of graphical renderings of the operating functions are given and discussed.<> View full abstract»

    Response-surface experimental design is explained, and it is shown that it offers a powerful tool for efficiently characterizing and optimizing a complex process. Engineers end up with a picture and the ability to predict what will happen for any given set of operating conditions. It is a tool that can be safely used with proper understanding of experimental strategy as opposed to statistical knowledge.<> View full abstract»

    A description is given of the PPCU, a system used to verify the data and electrical interfaces of space shuttle payloads before forwarding them to integrated testing and, finally, to the space shuttle orbiter cargo bay. The system, which was built with off-the-shelf hardware and software, accomplishes this by simulating the electrical and data characteristics of the space shuttle's onboard interfaces. The function of each of the PPCU subsystems is explained, and the operation of the overall system is discussed.<> View full abstract»

    A low-cost method for improving mobile FM reception is discussed. The problem suffered by FM in a moving car is the sporadic distortion of reception due to multipath propagation. Improvement can be obtained by multi antenna diversity system because the probability of simultaneous distortion on all antennas is greatly reduced as the number of antennas increases.<> View full abstract»
