Control of distributed energy resources and load tap changers to enhance the long-term voltage stability of transmission networks
Control de recursos energéticos distribuidos y cambiadores de tomas en carga para mejorar la estabilidad de tensión de largo plazo de redes de transporte
(2023-11)
La estabilidad de tensión es la capacidad de un sistema eléctrico de potencia de mantener tensiones aceptables tras una perturbación. En redes de transporte, esta capacidad se ve comprometida a largo plazo cuando se suplen ...
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 ...
Clasificación de quimiosensibilidad tumoral en muestras del proyecto TCGA mediante la integración de datos genómicos del cáncer
(2019-08)
La enfermedad del cáncer causa millones de muertes en todo el mundo y miles en Costa Rica, y el tratamiento del cáncer causa también una carga económica inmensa en el sistema de seguridad social porque las drogas contra ...
Automatic Translation of Spanish Natural Language Commands to Control Robot Comands Based on LSTM Neural Network
(2019)
In this paper, we propose a high level layer able to
translate motion commands in natural spanish language to a
formal intermediate representation called Robot Control
Language (RCL). The layer was built by using the ...
Performance Improvement of Alkaline–Electrolyte Aluminum–Air Batteries by NH4VO3-Based Additives
(2022-02-09)
Due to their high theoretical volumetric capacity, aluminum–air batteries are an up-and-coming alternative for energy storage in mobile applications. However, there are still several problems that need to be solved to make ...
Comparative Efficiency Study of Two Proposed Designs Tested in Water and Air Cooling Conditions for a High Power Humanoid Robot Hollow Joint
(2018)
When a robot is designed, usually the weight of the same motors limits the maximum payload of the robot. While the designer tries to increase the power of the motors to give the robot better payload capacity, by doing so, ...
Development of an alternative procedure to verify “in situ” volumetric diaphragm type gas meters for residential use
(2015-09-21)
Cet article montre les performances métrologiques du compteur de gaz portatif mis au point pour les mesures de volume dans le domaine, quand il fonctionne à différentes conditions à l'obtention du diplôme, mais similaires ...
Parallelization of a Multipartite Graph Matching Algorithm for Tracking Multiple Football Players
(2018)
This work describes the parallel methodology for a football tracking algorithm based on multipartite graphs using MPI and OpenMP. The proposed algorithm use a consumer-producer scheme to overlap the computing time of the ...
Resolution improvements on poly(methyl methacrylate) as electron-beam resist
(San José, Costa Rica, 2012-10-23)
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 ...
