Direct Connection of Supercapacitor-Battery Hybrid Storage System to the Grid-tied Photovoltaic System
(2018-08-30)
Penetration rate of grid-connected photovoltaic (PV) generation to the existing utility grid is rapidly increasing over the years. Since the power generated from PV systems fluctuate according to the weather condition, ...
Work inspections as a control mechanism for mitigating work accidents in Europe
(Instituto Tecnológico de Costa Rica, 2020)
The effect of eccentric strength training on heart rate and on its variability during isometric exercise in healthy older men
(2009-01-01)
The purpose of this study was to investigate if chronic eccentric strength training (ST) affects heart rate (HR) and heart rate variability (HRV) during sub-maximal isometric voluntary contractions (SIVC). The training ...

Analogue control of the slew-rate in LIN bus digital transitions using translinear circuits
(SpringerDordrechtHolanda, 2012)
Controle adaptativo multi-rate para eficiência energética em sistemas de controle via redes sem fio
(Universidade Estadual Paulista (Unesp), 2016-09-09)
Com os recentes avanços das tecnologias sem fio e a proliferação de sensores sem fio, há um crescente interesse na implementação de Sistemas Controle via Redes Sem Fio (WNCSs), que fornecem vantagens em relação às arquiteturas ...
Autonomic control of heart rate during orthostasis and the importance of orthostatic-tachycardia in the snake Python molurus
(Springer, 2014-10-01)
Orthostasis dramatically influences the hemodynamics of terrestrial vertebrates, especially large and elongated animals such as snakes. When these animals assume a vertical orientation, gravity tends to reduce venous return, ...
Rate constants determined by nuclear magnetic resonance
(Academic Press, 2001)
Fast kinetic methods are used to measure reactions that take place in less time than required to mix the reagents manually and to measure the reaction by usual methods, like UV-visible spectrophotometry and fluorescence. ...
