Desarrollos tecnológicos en Costa Rica en apoyo a la comunidad sorda
(Instituto Tecnológico de Costa Rica, 2022)El papel de la tecnología en los procesos de desarrollo e interacción en la vida cotidiana es incuestionable en la actualidad. Esto se hace aún más evidente para las poblaciones con algún tipo de discapacidad, quienes ... -
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 ... -
A fault-tolerance protocol for parallel applications with communication imbalance
(IEEE, 2015)The predicted failure rates of future supercomputers loom the groundbreaking research large machines are expected to foster. Therefore, resilient extreme-scale applications are an absolute necessity to effectively use ... -
Assessing the performance of several rainfall interpolation methods as evaluated by a conceptual hydrological model
(Scopus, 2016)The objective of this study was to assess the performance of several rainfall interpolation methods as evaluated by a conceptual hydrological model. To this purpose, the upper Toro River catchment (43.15 km2) located in ... -
On the Significance of Leaf Sides in Automatic Leaf-based Plant Species Identification
(IEEE, 2016-11)Because the front side of a leaf and the underside are functionally very different – the former captures sunlight to produce photosynthesis and the latter absorbs carbon dioxide and releases oxygen and vapor – they typically ... -
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 ... -

Digital integrated circuit implementation of an identification stage for the detection of illegal hunting and logging
(Institute of Electrical and Electronics Engineers Inc., 2015-09)Results of the VLSI implementation of an acoustic classification system's identification stage, intended for the detection of gunshots and chainsaws in a protected tropical area, are shown, with the idea of later building ... -
Design of an IDM-based determinant computing unit for a 130nm low power CMOS ASIC acoustic localization processor
(Institute of Electrical and Electronics Engineers Inc., 2015-09)A determinant computing circuit in floating point format has been designed and tested for use in a CMOS ASIC acoustic localization processor. The Internal Division Method (IDM) was used to implement the operation, employing ... -
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 ... -
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 ... -
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 ... -
Using migratable objects to enhance fault tolerance schemes in supercomputers
(IEEE Computer Society, 2015-07)Supercomputers have seen an exponential increase in their size in the last two decades. Such a high growth rate is expected to take us to exascale in the timeframe 2018-2022. But, to bring a productive exascale environment ... -
