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 ...
Recommendations for the use of tree models to estimate national forest biomass and assess their uncertainty
(Springer-Verlag France, 2015-09)
Three options are proposed to improve the accuracy of national forest biomass estimates and decrease the uncertainty related to tree model selection depending on available data and national contexts. Introduction: Different ...
Pellets Evaluation Made from Tropical-Climate Agricultural and Forestry Crops of Costa Rica with a Domestic Stove
(Springer Netherlands, 2015-12)
The present study shows the results of the evaluation of the pellets made from two forestry crops and eight agricultural crops in Costa Rica by employing a 50 kW domestic stove. Methods: The following variables were ...
Implementation of stellarator of Costa Rica 1 SCR-1
(26th IEEE Symposium on Fusion Engineering, SOFE 2015, 2015)
The SCR-1 is a small modular stellarator designed, constructed and is being implemented at Instituto Tecnológico de Costa Rica. The project is its final phase of commissioning and it is expected to be operational in June ...
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 ...
General, physical and mechanical properties, termites resistance and drying defects of lumber of Tectona grandis from plantations of different climatic and sites fertility condition
(Springer India, 2015-06)
The influence of climatic and site fertility conditions affect wood quality from fast growing trees. The change in tree diameter, thickness of sapwood, heartwood percentage and bark and pith tissue, physical and mechanical ...
Quality of pellets made from agricultural and forestry crops in costa rican tropical climates
(North Carolina State University, 2015)
Pellets may be produced with different types of agriculture or forestry crops in Costa Rica. This work evaluated the energy, physical, and mechanical properties of pellets fabricated from 12 types of agricultural and ...

(OSA - The Optical Society, 2015)
A four-channel WDM silicon photonic transmitter with integrated lasers and modulators driven by low-power 32nm CMOS drivers, is demonstrated to operate at a data rate of 4×28Gb/s with BER<10-12 and power consumption of 10.0pJ/bit.
Design of a Prototype of Water Purification by Plasma Technology as the Foundation for an Industrial Wastewater Plant.
(Institute of Physics Publishing, 2015-03)
In order to mitigate the contamination of water sources due to the spill of sewage without any kind of treatment, mainly generated by the industrial sector; a prototype of water purification by plasma technology has been ...
Landscape-scale controls on aboveground forest carbon stocks on the Osa Peninsula, Costa Rica
(Public Library of Science, 2015-06)
Tropical forests store large amounts of carbon in tree biomass, although the environmental controls on forest carbon stocks remain poorly resolved. Emerging airborne remote sensing techniques offer a powerful approach to ...
