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 ...
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 ...
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 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 ...
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 ...
LaGeR workbench: A language and framework for the representation and implementation of device-agnostic gestural interactions in 2D and 3D
(Springer Verlag, 2015)
The recent rise of virtual and augmented reality applications, ambient intelligence, as well as video games have encouraged the proliferation of gestural input devices such as the Razer Hydra, Leap Motion Controller, and ...
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 ...
Power, Reliability, Performance: One System to Rule Them All
(IEEE, 2016)
En un diseño basado en el marco de programación paralelo Charm ++, un sistema de tiempo de ejecución adaptativo interactúa dinámicamente con el administrador de recursos de un centro de datos para controlar la energía ...
Arquitectura de Alta Disponibilidad en DSpace: Repositorio TEC
(Instituto Tecnológico de Costa Rica, 2015)
En la actualidad, el acceso rápido, seguro y eficiente a la información es un aspecto muy importante para todos los usuarios. Un repositorio institucional que no garantiza el acceso a su contenido de forma eficiente y ...
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, ...
