Digital design learning at Register Transfer (RT) level requires practical and complex examples as learning progresses. FPGAs and development boards offer a suitable platform for the implementation of these designs. However, classroom practice sessions usually last two hours, which does not allow the complexity of the designs be high enough. For this reason, interesting designs that can be made in several sessions are required. In this paper, the construction of a distance measuring system is presented. For this purpose, a distance measurement module based on ultrasound is available, the results are displayed in 7-segment displays on a Nexys4 board. This approach has been applied to three Electronic subjects at the University of Seville. The degree of satisfaction on the part of the students as well as the result of the evaluation of the experience by the teachers involved are shown.

The aim of this paper is to present a standard set of power system data with benchmark results against which direct stability techniques to assess transient stability could be compared and tested. The test systems have been selected to display a wide range of dynamic characteristics to provide a robust test of the efficacy and accuracy of the various analytical techniques to analyze transient stability. Transient stability test system data and benchmark results obtained from two commercially available time domain stability analysis packages are presented in this paper.

A new dynamic programming algorithm for fast rescheduling thermal generation is presented. The savings in computational times are brought about by the introduction of two new techniques: the variable truncation dynamic programming and the limitation of the solution space to be searched. Several examples on a 20 machine system are used to illustrate the application of the algorithm and to show that optimal solutions are obtained at significantly reduced computational times.
