In this document is presented the implementation of the programming schedules as a method of lighting control, to perform a total saving and a personalized saving using neural networks. With the acquisition of a series of data about the operation of five lightings located in different parts of a specific house, it was designed a neural network to illuminate it and was implemented this design to the...
In this paper, the application of neural networks is proposed to solve the problem of voltage sags state estimation. This problem is based on estimating the voltage sags occurrence frequency at non monitored buses from the recorded voltage sags occurrence frequency at a limited number of monitored buses. The fault position method is used to formulate the optimization problem. The methodology is implemented...
Sensory systems for localization and mapping based on ranging allows to obtain not only the position of a mobile object but also the position of the beacons or landmarks. Using only ranging, the beacon positions are often calculated without needing to compute all the spatial relations among them. In this work, a preliminary study about the use of relative positioning algorithm to obtain a map of active...
This article describes the architecture of two broadband satellite communication systems using a very small aperture terminal which have been installed on two Spanish oceanographic research vessels. The potential use, equipment and their characteristics are studied and compared. Analysing four parameters (jitter, round time trip, package loss and throughput), system configuration has been modified...
Cardiac Resynchronization Therapy is a treatment for bi-ventricular asynchronism. It can be optimized by the identification of the most effective pacing sites. The aim of this study is to provide a helpful tool to perform this identification by the fusion of electrical and anatomical information resulting from Electro-Anatomic Mapping (EAM) data and Multislice Computerized Tomography (MSCT) imaging...
The development of a new generation pneumatic ventricular assist device (VAD) required the design of valves for the optimization of its performance. Experiments and computer-based simulations under hydrostatic conditions were analyzed in order to test and compare two low-cost elastomer valve designs. The trileaflet valve design showed a superior hydrostatic performance, having almost a ratio of 1:2...
