In this paper the linear analysis capabilities of two software packages are evaluated and compared. The paper also illustrates the impact of the models of the power system components on the location of the eigenvalues. Eigenvalue analyses are not only dependent on the properties of the investigated system, but also on the software package that is used, as well as on how the components of the power system are modeled. Therefore, conclusions can differ when studying the same power system with different software packages.","PeriodicalId":324953,"journal":{"name":"IEEE SoutheastCon, 2004.

Unlike the conventional digital system designs, where the logic and functionality are optimized, modern designs call for integration of several digital sub system units for an integrated digital system. Such a scheme needs a collection of digital circuits in a library. It is prohibitive to have very many of different circuits and the associated software coding for each of them. Rather, it is advantageous to identify fundamental digital components and develop the VHDL or Verilog code for these components. Use this code recursively, to develop higher density and more complex circuits.","PeriodicalId":324953,"journal":{"name":"IEEE SoutheastCon, 2004.

Where once test-points could be located at strategic points throughout the design, today the spacing between the components and the critical nature of layout concerns no longer will support that approach. The increase in complexity requires circuit partitioning for adequate testing. Recent advances in packaging and process development, as well as extended characterization of the analog characteristics in the latest generation of analog switch products, bring many advantages to solving these design problems. These desirable improvements include: wide operating voltage range, very low power of operation, rail to rail signal handling, wide bandwidth, low on resistance, fast enable and disable times, and very small package sizes. These improved characteristics simplify the design process by minimizing the effects that inserting a switch will have in the functionality of the circuit being modified.","PeriodicalId":324953,"journal":{"name":"IEEE SoutheastCon, 2004.

Genetic algorithms and the Virtual Reality Modeling Language ¿vrml¿ are used to design the software and the simulator respectively. It is assumed that the robots are located arbitrary at known starting positions and need to be moved to target positions in a known multi-obstacle three-dimensional environment. The factors considered for finding optimum paths for the group of mobile robots are the size and location of obstacles in the environment and the elevations of the environment. The developed software was tested on an aerial picture taken by a satellite imaging device for an outdoor environment. The size of obstacles, elevations present in the environment and starting positions of the robots and target position are all identified on the digital image in a form of grid map. The genetic algorithm takes information about the environment from the grid map, the results of processed pictures, and searches for optimum paths to move a group of mobile robots to specified targets. It is found that genetic algorithms converge and give better solutions to path planning in an environment where results are difficult to obtain.","PeriodicalId":324953,"journal":{"name":"IEEE SoutheastCon, 2004.
