Optimal control of MIMO dead-time linear systems with dead-time compensation structure
(Universidad Nacional de Colombia (Sede Medellín). Facultad de Minas., 2017-01-01)
State space optimal controllers became popular over the last decades mainly because of its performance and robustness properties, as well as easy extension for multi-variable systems (MIMO). On the other hand, many industrial ...
Adaptive LAMDA applied to identify and regulate a process with variable dead time
(Institute of Electrical and Electronics Engineers Inc., 2020-01-01)
In this paper, an adaptive intelligent controller based on the fuzzy algorithm called LAMDA (Learning Algorithm for Multivariable Data Analysis) is presented in order to identify and regulate a process with variable dead ...
The effect of changing the mode of ventilation on the arterial-to-end-tidal CO2 difference and physiological dead space in laterally and dorsally recumbent horses during halothane anesthesia
(2000-12-01)
Objective - To evaluate the effect of changing the mode of ventilation from spontaneous to controlled on the arterial-to-end-tidal CO2 difference [P(a-ET)CO2] and physiological dead space (VD(phys)/VT) in laterally and ...
Modeling and control of nonlinear systems using an Adaptive LAMDA approach
(Elsevier BV, 2020-01-01)
This paper presents a soft computing technique for modeling and control of nonlinear systems using the online learning criteria. In order to obtain an accurate modeling, and therefore a controller with good performance, a ...
The effect of a hydrogen sulfide releasing molecule (Na2S) on the cold storage of livers from cardiac dead donor rats: a study in an ex vivo model
(Elsevier Science Inc, 2015-08)
Liver transplantation is currently the preferred treatment option for end-stage liver disease. Donation after cardiac death was a common practice in the early years of organ donation before brain death criteria were ...
UAV-based photogrammetric point clouds and hyperspectral imaging for mapping biodiversity indicators in boreal forests
(2017-10-19)
Biodiversity is commonly referred to as species diversity but in forest ecosystems variability in structural and functional characteristics can also be treated as measures of biodiversity. Small unmanned aerial vehicles ...
Canopy characteristics and behavior of Nellore heifers in Brachiaria brizantha pastures under different grazing heights at a continuous stocking rate
(Sociedade Brasileira de Zootecnia, 2011-11-01)
The objective of this study was to evaluate the Brachiaria brizantha cv. Marandu canopy structure maintained at different grazing heights under a continuous stocking rate and with a dietary supplementation strategy for the ...
Avaliação morfológica do capim-aruana em três sistemas (campo aberto, silvipastoril de canafístula e silvipastoril com louro)
(Universidade Tecnológica Federal do ParanáDois VizinhosBrasilBacharelado em ZootecniaUTFPR, 2018-11-19)
The importance of evaluating the morphology of the Aruana grass in different production systems allows the producer to choose a system whose results are better in forage mass production and consequently higher quality, ...
