Automatic recognition of accessible pedestrian signals
(2018)
Accessible pedestrian signals (APS) enhance accessibility in streets around the world. Recent attempts to extend the use of APS to people with visual and audible impairments have emerged from the area of audio signal ...
Supporting User Awareness Using Smart Device-Based Notifications
(2016)
This paper provides an overview of a doctoral research project which
focuses in developing a framework to allow smart device-based notifications to
provide user awareness. Notifications are mechanisms by which the user’s ...
Propuesta para la guía de diseño mecanística-empírica para pavimentos flexibles y semi-rígidos de Costa Rica
(2020-09-22)
En Costa Rica el diseño de pavimentos se realiza utilizando principalmente metodologías con un trasfondo empírico, siguiendo recomendaciones de la AASHTO de 1993, manuales internacionales con muchos años de antigüedad o ...
FastWorks FPA: Una herramienta para automatizar la medición del tamaño funcional
(2017-09-04)
La automatización de la medición del tamaño funcional es un reto para la industria del software. Una solución automatizada de conteo no es trivial, debido a que debe proporcionar un nivel aceptable en la exactitud de las ...
Evaluation of potential Spanish text markers on social posts asfeatures for polarity classification
(2017)
This work describes the identification and evaluation process of potential text markers for sen-timent analysis. Evaluation of the markers and its use as part of the feature extraction processfrom plain text that is needed ...
The Impact of the National Housing Program on Residential Segregation in Costa Rica
(2022-07-18)
Residential socio-economic segregation in Costa Rica had an overall decreasing
trend between 1973 and 2011 because of a sustained reduction in the amount
of lower income households. However, in 1986, the national housing ...
Medidas de intensidad sísmica independientes de la orientación del sensor: Aplicación a una base de datos con acelerogramas de Costa Rica, El Salvador y Nicaragua
(2015-01-01)
En esta investigación se han comparado las medidas de intensidad del movimiento del suelo, para una base de datos con acelerogramas de Costa Rica, Nicaragua y El Salvador. Estas medidas están basadas en una serie de registros ...
Correlación entre la forma de la razón espectral H/V con la estratigrafía del subsuelo en 10 sitios de estudio
Correlation between H/V spectral ratio shape and subsoil stratigraphy in 10 selected sites
(2018-06-29)
Es posible que al aplicar la técnica de la razón espectral para vibraciones ambientales no se
logren identificar picos bien definidos que se asocien a contrastes significativos entre el suelo
y el basamento. Sin embargo, ...
Evolution of microcontroller’s course under the influence of arduino
(2016)
This paper presents the evolution of an undergraduate microcontroller’s course that uses Arduino as its main platform. In earlier versions of the course, it focused on teaching Arduino’s framework and its interconnection ...
Aud-SWIPE-P: A parallelization of the Aud-SWIPE pitch estimation algorithm using multiple processes and threads
(Acta Press. Artificial Intelligence and Applications / 794: Modelling, Identification and Control / 795: Parallel and Distributed Computing and Networks / 796: Software Engineering / 792: Web-based Education (AIA 2013), 2013-02-11)
In this work we implement a parallel version of the pitch estimation algorithm Aud-SWIPE. The new implementation, Aud-SWIPE-P produces a remarkable acceleration, making it usable in applications where it was not efficient ...
