Detector predictivo de faltas en máquinas eléctricas rotativas.El sistema objeto de la presente invención permite conocer el estado de salud de una máquina eléctrica en tiempo real, mediante la medida de la corriente de estator y la detección de deterioro

This paper presents a new technique for programming SC circuits using a single time-multiplexed capacitor bank, achieving a significant reduction in capacitance area. Simulation results of a programmable biquad low pass filter show the validity of the proposed method.

This paper is intended to compare the performance of a Band-Pass converter structure and its Low-Pass prototype 2nd order Sigma-Delta Analog to Digital converter. For this purpose Matlab simulations for the 4th order Band-Pass converter have been performed and its power consumption calculated when using the equivalent Op-Amp used m the Low-Pass...

This work presents the determination of a Pulsed Laser SEU Cross-Section (Count Statistics). In this work, a coincidence detector has been used to count fault events by comparing the digital VLSI circuit under test with a replica of the design running on a control FPGA. A SEU is declared when a specific fault pattern is detected. The target...

Radiotherapy is nowadays a proven technique in cancer treatments. Within the evolution of radiotherapy treatments towards more complex techniques, the need of new dosimetric methods for treatment verifications has appeared. In order to reach an improved dosimetric method, a collaboration was started to transfer knowledge from nuclear reaction...

In this work we present the output factor measurements of a clinical linear accelerator using a silicon strip detector coupled to a new system for complex radiation therapy treatment verification. The objective of these measurements is to validate the system we built for treatment verification. The measurements were performed at the Virgin...
