A comparison of different bio-inspired methods is presented for the problem of tuning the parameters of a PID industrial controller for second order plus time delay plants. The compared algorithms are representative of ...

The penetration of Low Carbon Technologies (LCTs) is expected to increase in the near future given the attractive incentives from governments, the cost-effectiveness of the technologies and the appearance of Smart Grid ...

Power systems are operated close to their stability limits and this increases the probability of cascading outages leading to large-area blackouts. To mitigate these phenomena, intentional controlled islanding (ICI) has ...

This paper presents an algorithm to estimate lost bus voltage measurements in balanced distribution networks regulated by centralized control schemes. The objective is to feed controllers with reliable estimations of lost ...

Incluye la investigación desarrollada para crear el primer microscopio de efecto túnel en Costa Rica. Este sistema se basa en la utilización de las propiedades de movimiento nanométrico de los materiales piezoeléctricos y ...

En esta tesis se presentan los resultados de la aplicación de la técnica denominada espectroscopía de ruido Flicker para el análisis del proceso de producción del silicio poroso, un material que exhibe interesantes propiedades ...

The present thesis expands the topic of lithographic resolution improvement of poly(methyl methacrylate) (PMMA) as a positive tone electron-beam resist. The investigation used electron-beam lithography (EBL) to define ...

This paper presents a generic trapezoid-type capability curve for any distributed generation technology. This curve is used to estimate the machine reactive power limits in terms of the actual active power and terminal ...

This paper presents a tool to automatically generate distribution network models for the power engineering software OpenDSS. The tool was developed in a free and open source Geographical Information System (GIS) software ...
