Tissue damage-tracking control system for image-guided photothermal therapy of cancer
(2022)
Photothermal therapy (PTT) is a type of cancer treatment capable of damaging tumors using laser irradiation. This procedure can be a promising approach to complement current cancer therapies, due in part to its minimal ...
Optimal immune PI tuning rules for networked control systems with long time delays
(2021-11)
This work presents a novel method for Networked Control Systems (NCS) with long time delays based on proportional-integral (PI) control with an immune feedback algorithm. Moreover, a simple set of tuning rules is presented ...
Robust PI/PID controllers for load disturbance based on direct synthesis
(2018-10)
It is recognized that disturbance rejection is much more important than set-point tracking for many process control applications, leading set-point tracking to a secondary level of interest. In this paper a proposal for ...
Descubrimiento del estilo de aprendizaje dominante en estudiantes de Matemática superior
Discovering dominant learning styles in higher level Math students
(2020)
La presente investigación se desarrolló con el objetivo de descubrir cuáles son los estilos de aprendizaje dominantes en estudiantes de Matemática Superior de la carrera de Ingeniería Eléctrica en la Universidad de Costa ...
Factores determinantes en la escogencia de la carrera de Ingeniería Química en la Universidad de Costa Rica
(2021-08)
El lento crecimiento en la matrícula de mujeres en las carreras de ingeniería ha motivado desde Mujer en la Ingeniería a preguntarse ¿por qué pasa esto?, sin embargo, una de las carreras que típicamente tiene paridad de ...
Exploring the boundaries of Solar Home Systems (SHS) for off-grid electrification: Optimal SHS sizing for the multi-tier framework for household electricity access
(2019-04-15)
With almost 1.1 billion people lacking access to electricity, solar-based off-grid products like Solar Home Systems (SHS) have become a promising solution to provide basic electricity needs in un(der)-electrified regions. ...
Quantifying the benefits of a solar home system-based DC microgrid for rural electrification
(2019)
Off-grid solar home systems (SHSs) currently constitute a major source of providing basic electricity needs in un(der)-electrified regions of the world, with around 73 million households having benefited from off-grid solar ...
Análisis de estabilidad de un sistema no lineal con controladores PD inmune
(2022-04)
Este trabajo presenta el análisis y deducción de las condiciones que garantizan la estabilidad de un sistema de primer orden implementando un controlador PD en conexión con una no linealidad sectorial general usando el ...
Experimental study on transfer learning in denoising autoencoders for speech enhancement
(2020)
The quality of speech signals is affected by a combination of background noise, reverberation, and other distortions in real-life environments. The processing of such signals presents important challenges for tasks such ...
Multi-objective optimal tuning of two degrees of freedom PID controllers using the ENNC method
(2016-10-13)
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 ...
