In this paper the optimal control and parameters design of fractional-order vehicle suspension system are researched, where is described by differential equation. The linear quadratic state regulator designed based on theory, which applied to get force active system. A stiffness-damping added passive Based criteria, i.e. arising from accessional should be as close possible system, optimized obtained least square algorithm. An Oustaloup filter algorithm adopted simulate derivatives. Then,...
Abstract The decomposition experiments of Al(OH)3, Mg(OH)2 and Urea were conducted by TG DSC. thermal characteristics powders obtained. It shows that pyrolysis temperature (133 °C) was lower than Al(OH)3 Mg(OH)2, its heat absorption (1291J/g) larger Mg(OH)2. Suppression mechanisms gas explosion analyzed compared. results showed the performance better other two materials because Urea's faster rate, greater more free radical generated during period process. Also suppression confirmed experiments.
In order to improve the utilization rate of extracted coal-bed methane, effective safety measures for low concentration gas transmission line must be provided. this work, suppression explosion in a channel by powdered extinguishing agents (i.e. ferrocene and aluminium hydroxide) was investigated. The methane explosive mixture 9.5% volume. experimental is 150mm×150mm×500 mm dimensions, which three pairs obstacles spaced 100 apart configured enhance flame propagation speed. high speed camera...
Abstract An advanced heat‐resistant hyperbranched poly(phenylene sulfide) (HPPS) had been subjected to dynamic thermogravimetric analysis (TGA) in nitrogen. The presence of a single peak the DTG cures suggested that weight loss occurs stage. thermal decomposition kinetics analyzed by applying Kissinger, Friedman and Ozawa‐Flynn methods. E values determined for PPS using these analyses were found be 183.1, 189.2, 193.9 kJ mol −1 , respectively. Coats‐Redfern method was used discuss probable...
Nanofibrous substrate composite ultrafiltration membrane consisted of polyacrylonitrile (PAN) electrospun scaffold which was used as the substrate, and a thin crosslinked poly(vinyl alcohol) (PVA) barrier layer prepared by electrospinning technique combined with mixed solvent treatment. The thickness PVA nanofibrous top controlled changing depositing time. Through immersing PVA/PAN double-layer mats into water/acetone system, swollen to merge imperceptibly an integrated film on surface PAN...
Community-based Question Answering (CQA) summarization aims to generate a summary from collection of QA pairs about specific entity. Unlike well-structured texts such as dialogues, set often contains significant redundancy, including repetitive questions and similar answers. The above property makes it difficult for abstractive summarizers concentrate on salient pieces, resulting in duplication content omission important information. In this paper, we propose Focus Rectification SUMmarizer...
The optimal control of fractional-order active isolation system is researched based on the theory, and effect derivative passive also analyzed. mechanical model established where viscoelastic features materials are described by derivative. property in dynamical studied could be divided into linear stiffness damping. It found that both fractional coefficient order affect not only resonance amplitude through equivalent damping but frequency stiffness. Based feedback gain under harmonic...
In the paper, a novel type of neural network, referred to as network with cooperative weights is proposed achieve H <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">∞</sub> tracking performances for class unknown nonlinear dynamic system external disturbance. By Lyapunov method, overall closed-loop shown be stable. article, effect both approximate error and disturbance on attenuated prescribed lever ρ by adequately selecting weight factor r ;...
