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 ...

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 ...

In this paper the Enhanced Normalized Normal Constrained method is applied to find the optimal tuning of second order PID controllers. This tuning takes into account both the servo and regulatory modes simultaneously, as ...

El análisis comparativo de los precios de la electricidad es un tema central en las discusiones sobre competitividad y el Sistema Eléctrico Costarricense. Este trabajo se propone aportar elementos de análisis para tales ...

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 ...

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 ...

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 ...

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 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 ...
