Recalculo de la relación entre la aceleración pico efectiva y pico para sismos registrados en Costa Rica entre 1983 y 2019
(2020-02-11)
En el presente estudio se realiza un cálculo de la relación que existe entre la aceleración pico efectiva y la aceleración pico del terreno, utilizando la base de registros acelerográficos del Laboratorio de Ingeniería ...
Current seismic design regulations for Costa Rica
(1988-08-29)
Some comments on the earthquake engineering development in Costa Rica are given. A description of the newly started Strong Motion Instrumentation Program is given. The description includes remarks on both free field strong ...
Development of a Mobile Application for Robust Tuning of One- and Two-Degree-of-Freedom PI and PID Controllers
(2015-12-01)
This paper presents the development of a mobile application for Android systems devices, that helps in the control system design task. The application allows to compute the parameters of PID-type controllers. The controlled ...
Smart placement of a two-arm assembly for an everyday object manipulation humanoid robot based on capability maps
(2018)
A robot that will execute everyday object manip-
ulation tasks needs a competent body that can handle as many
different objects as possible in as many ways as possible. To
accomplish this, we must design the robot body ...
What do you think of fungi? Perceptions by “educated” groups in Honduras and Costa Rica
(2015)
This study was designed in order to compensate for the poor availability of information about the human-fungi interaction in Central America. We surveyed two “educated” groups of people in higher institutions within urban ...
New records of myxomycetes for Central America and comments on their regional distribution
(2017-06-21)
Several studies on myxomycetes in Central America during the last decade have greatly increased the
information on the morphological species present in the different countries of that region. Herein we present a
list of ...
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 ...
School gardens and biofertilization as a strategy towards climate change mitigation and adaptation in Costa Rica
Huertas escolares y biofertilización como estrategia hacia la mitigación y adaptación al cambio climático en Costa Rica
(2021-04-16)
School gardens are important for the conceptual integration of topics such as
climate change. Using a biofertilization experiment in a school garden, we evaluated four
experimental treatments and the student knowledge ...
Resultados del procesamiento de los acelerogramas del Instituto Nacional de Seguros. Sismo de Golfito, 3 de abril de 1983
(1987-07-06)
Procesamiento de los registros de aceleración obtenidos en la estación acelerográfica instalada por la Universidad de Costa Rica en un edificio de concreto reforzado (sede central del Instituto Nacional de Seguros). La ...
Analysis of Atomic Manipulation Tasks in human- shared scenarios (a Kitchen and a Collaborative Workshop Table) for a Humanoid Robot
(2018)
In this paper we analyze the vocabulary of an
action description language to be used, together with a low level
object controller, by a humanoid robot in two specific scenarios:
a kitchen and a collaborative workshop ...
