Understanding the link between benefits from protected areas and their relationship with surrounding communities: an exploration in Costa Rica
Protected areas are an essential strategy in preserving natural resources. A central aspect of protected area management is to maintain and improve their relationship with surrounding communities given that local conflicts ...
Does elevation influence the distributional patterns of tropical myxomycetes? A case study in Costa Rica
In order to test the hypothesis that elevation may be an important factor accounting for the distribution of myxomycetes in tropical forests, this project was designed and conducted in Costa Rica. Two lower elevational ...

Desarrollo verde e inclusivo en respuesta al cambio climático
Considerando que Costa Rica estará sumamente expuesta a la amenaza de un clima cambiante, la respuesta al cambio climático no puede esperar. Ya la mayor variabilidad climática y el fenómeno El Niño-Oscilación del Sur ...
Improved PID controller tuning rules for performance degradation/robustness increase trade-off
Definitely, robustness is an important feature that any control system must take into account, especially considering that the design is usually based on low-order linear models that represent the whole controlled process. ...
Multivariable decoupling set-point approach applied to a wastewater treatment plant
This paper presents a formulation for the inclusion of the second degree of freedom for MIMO system for decoupling purposes. The proposal is specially effective when combined with decentralized feedback controllers. Loop ...
Effect of Densification Conditions on Physical Properties of Pellets Made From Sawmill Residues
Sawmill residues produced in wood processing of Pilon (Hyeronimaalchorneoides) and Eucalyptus (Eucalyptus spp) species, were used to fabricate pellets with experimental design equipment. Different manufacturing conditions ...
Utilização de uma malha estruturada na análise do aerofólio s809
A análise numérica tem se tornado uma ferramenta essencial nas etapas do desenvolvimento de um projeto devido a sua capacidade de solução para fenômenos físicos descritos por leis de difícil solução analítica, economizando ...
Monitoring the moin beach to control morphological changes due the construction of the moin container terminal, Limon
The Moin Container Terminal (MCT) is a project under construction that represents one of the largest investments in Latin American port facilities. The first stage consists of a seven million cubic meter sand fill constructed ...
Model reference pi controller tuning for second order inverse response and dead time processesand science
In this paper, a One-Degree-of-Freedom PI controller is optimized using the model reference tuning approach for a Second Order Inverse Response and Dead Time Process operating as a servo control. In addition, a graphic ...
