Improved PID controller tuning rules for performance degradation/robustness increase trade-off
(2016-09)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. ... -
Use of drone technology and photogrammetry for beach morphodynamics and breakwater monitoring
(2016-05-10)Results from the use of UAV-based photogrammetry for monitoring changes in beaches and breakwaters are presented. Main recommendations are provided on the basis of lessons learned about the collection of reliable results ... -
Multi-objective optimal tuning of two degrees of freedom PID controllers using the ENNC method
(2016-10-13)In this paper the Enhanced Normalized Normal Constrained method is applied to find the optimal tuning of second order PID controllers. This tuning takes into account both the servo and regulatory modes simultaneously, as ... -
Multivariable decoupling set-point approach applied to a wastewater treatment plant
(2016-10-21)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 ... -
Using the oxyhydrogen as an additive to increase the performance of an internal combustion engine
(2016-06)Reducing the pollution emission associated with oil combustion is gaining an increasing interest worldwide. Recently, Brown’s gas (HHO gas) has been introduced as an alternative clean source of energy. A system to generate ... -
Effect of Densification Conditions on Physical Properties of Pellets Made From Sawmill Residues
(2016)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
(2015-04)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
(2016-05-10)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 ... -
Desarrollo verde e inclusivo en respuesta al cambio climático
(2016-04)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 ... -
Understanding the link between benefits from protected areas and their relationship with surrounding communities: an exploration in Costa Rica
(2016-03-12)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
(2016)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 ...
