Automated plant species identification: Challenges and Opportunities
(IFIP Advances in Information and Communication Technology, 2016)
The number of species of macro organisms on the planet is
estimated at about 10 million. This staggering diversity and the need
to better understand it led inevitably to the development of classification
schemes called ...
Analysis of source separation algorithms in industrial acoustic environments
(Institute of Electrical and Electronics Engineers Inc., 2015)
This paper shows the results from the computation cost evaluation of three blind source separation algorithms. The algorithms tested were: FastICA, Adaptive Algorithm Based on Natural Gradient, and Adaptive EASI Based on ...
A Parallel Framework with Block Matrices of a Discrete Fourier Transform for Vector-Valued Discrete-Time Signals
(Hindawi Publishing Corporation, 2015)
This paper presents a parallel implementation of a kind of discrete Fourier transform (DFT): the vector-valued DFT. The vector-valued DFT is a novel tool to analyze the spectra of vector-valued discrete-time signals. This ...
Desarrollo de herramientas para la visualización de modelos de datos científicos
(Instituto Tecnológico de Costa Rica. Vicerrectoría de Investigación y Extensión (VIE). Escuela de Ingeniería en Computación, 2015)

Camel: collective-aware message logging
(Kluwer Academic Publishers, 2015-03)
The continuous progress in the performance of supercomputers has made possible the understanding of many fundamental problems in science. Simulation, the third scientific pillar, constantly demands more powerful machines ...
Simulation-based evaluation of school reopening strategies during COVID-19: a case study of São Paulo, Brazil
(Instituto Tecnológico de Costa Rica, 2021)
During the COVID-19 pandemic, many countries opted for strict public health measures,
including closing schools. After some time, they have started relaxing some of those restrictions.
To avoid overwhelming health systems, ...
Going deeper in the automated identification of Herbarium specimens
(BioMed Central, 2017-08-11)
Hundreds of herbarium collections have accumulated a valuable heritage and knowledge of plants over several centuries. Recent initiatives started ambitious preservation plans to digitize this information and make it available ...
A top-down design approach for an automated testing framework
(Springer Verlag, 2015)
Mobile applications have become popular work tools. Portability and ease of Internet connectivity are characteristics that favor this adoption. However, mobile applications sometimes incorrectly process events associated ...
