Introdução: A insuficiência cardíaca é uma das principais causas de morbimortalidade no mundo, principalmente, em idosos. doença definida como disfunção cardíaca, onde o coração não apresenta capacidade gerar um volume sistólico adequado que supra as necessidades metabólicas do organismo, ou capaz, porém às custas níveis pressóricos enchimentos maiores. Objetivo: Analisar manejo dos pacientes com aguda na emergência. Metodologia: Trata-se revisão integrativa últimos 3 anos, período 2022 a...
In recent years, several solutions for structural vibration control of buildings have been proposed. particular, the combination base-isolated structures with complementary variable damping devices has successful in reducing base isolator displacements without increasing building superstructure response when subjected to earthquake loads. this paper, a magnetorheological device is installed on 2-DOF mechanical model mounted an experimental uniaxial shaking table. A simple numerical...
A numerical and experimental analysis of semi-active (SA) control strategies for controlling seismic-excited structures is presented. physical model consisting a two degree-of-freedom (2DOF) mechanical system with magneto-rheological (MR) damper was developed to evaluate this concept at LNEC's shaking table. Linear elastic viscous models were used describe the behavior 2DOF system. Modified Bouc-Wen MR damper. Four distinct implemented evaluation. The associated controllers tuned using...
A predictive control strategy in conjunction with semiactive algorithms is proposed for damping of base-isolated structures employing fluid dampers when subjected to earthquake loads. The controller considers the delays resulting from device’s dynamics and an observer state estimation. Twenty artificial accelerograms were generated according Eurocode 8 Portuguese territory considered numerical simulations structure representative model. results a parametric study on single degree freedom...
Controlling the air quality is of utmost importance in today buildings. Vertical curtains are often used to separate two different climatic zones with a view reduce heat transfer. In fact, this research work proposes an curtain aimed ensure proper separation between zones, clean one and contaminated one. The methodology includes: (i) small-scale tests on water models that contamination does not pass through curtain, (ii) analytical development integrating main physical characteristics plane...
