OpenDSS-Based Distribution Network Analyzer in Open Source GIS Environment
The adoption of low carbon technologies (e.g., photovoltaic systems) is expected to increase in the near future given their contribution to reduce greenhouse gas emissions. However, high penetrations of these new technologies ...
Estimation of Lost Voltage Measurements in Distribution Networks
Estimación de medicines de tensión perdidas en redes de distribución
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 ...
Multi-objective optimal tuning of two degrees of freedom PID controllers using the ENNC method
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 ...
A comparison of bio-inspired optimization methodologies applied to the tuning of industrial controllers
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 ...
A risk-based methodology for defining the time of intentional controlled islanding
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 ...
Distribution Network Model Builder for OpenDSS in Open Source GIS Software
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 ...
Identification of Costa Rican speaker’s age group based on acoustic vowel analysis
The identification of the speaker’s age is a fundamental task in human-computer interaction. In particular, the recognition of children has drawn attention from the research community due to the vulnerability of se persons ...
Pushing cylinders: Expanding on object-based manipulation
Competent assistant robots need to understand their environment to be able to perform skilled manipulation tasks. One way of achieving it is to have knowledge about the physical behaviour of objects and how they respond ...
An Object Manipulation System Architecture for Humanoid Robots Based on Primate Cognition
Currently one of the most important challenges is to bring robots out of factory floors to work alongside humans. Because these environments are characterized by a very large variety of objects, a key factor is to provide ...
Robotic architecture design to map an action language to a low level motion commands for skillful manipulation
Diseño de una arquitectura robótica para mapear un lenguaje de acción a comandos de movimiento de bajo nivel para manipulación hábil
This paper gives an overview of a robotic architecture meant for skillful manipulation. This design is meant to close the gap between the high level layer (reasoning and planing layer) and the object model system (physical ...
