A cascaded model is proposed to establish the quantitative structure–activity relationship (QSAR) between overall power conversion efficiency (PCE) and quantum chemical molecular descriptors of all-organic dye sensitizers. The a two-level network in which outputs first level (JSC, VOC, FF) are inputs second level, ultimate end-point PCE dye-sensitized solar cells (DSSCs). combines methods machine learning methods, further including calculations, data division, feature selection, regression,...
To implement high-speed and smooth start-up process of large-thrust heavy-load cylinders, a mathematical model based on the Van der Waals equation has been established compared with computational fluid dynamics (CFD) simulation results. The influence pipe diameter load mass characteristics is analyzed. results CFD are consistent maximum error occurs in gas flow at congested state. average rate two models this state 8.161kg/s 8.536kg/s respectively, an 4.4%. larger tube process, greater...
For the problem of extinguishing fire under car in spray booths, a low-pressure air-water curtain method was proposed, and traditional solid cone nozzles, fan-shaped six-fusiform orifice nozzles were selected. The principle analyzed, experimental scheme system established. liquid characteristics tested spraying booths. results showed that effective range time better than those water mist, lateral conventional vertical spraying, fusiform larger nozzle nozzle. also effect related to horizontal...
An adequate hunting stability margin is required through the optimisation and matching of bogie suspension parameters for high-speed trains. Moreover, dynamics design particularly important robust lateral to adapt wheel–rail wear track deformation. The vehicles, as well contact state adaptability should be taken into account. In this regard, Pareto different stages executed. A method centralised key based on vehicle presented, principle two typical vehicles summarised. addition, in order...
The aim of the study is to design a secondary yaw suspension that will control both low-frequency body motion and bogie hunting under different wheel–rail equivalent conicities. In order enable high-speed train adaptively adjust wheel tread wear stages improve lateral dynamic performance vehicle in extreme contact states without any sensors systems, eddy current damper with parallel inerter as proposed, in-depth research on its working mechanism conducted. By establishing theoretical...
The suspension parameters are optimized to improve the dynamic performance of high-speed train with severe tread wear and suppress formation wear. Except for common indicator high-conicity stability (Ahigh) vehicle wear, a hollow index (HWI) is proposed reduce development rate wheel Moreover, low-conicity ride comfort (Wlow) considered dynamics new tread. Yaw stiffness (YS) ratio yaw damping lateral (RYL) characterize matching. Results show that HWI strongly positively correlated Wlow,...
Abstract This paper reports the results of a seismic performance study precast shear wall with new horizontal connection. The connection is rabbet-unbonded connection, which composed rabbets and unbonded rebar segments. are used to improve capacity prevent slippage segments ductility energy dissipation. Three specimens were tested different parameters under cyclic quasi-static loading. test showed that specimen larger level had richer hysteresis curve, ductility, dissipation, slightly...
Origami enables the folding of objects into a variety shapes. This paper presents swimming robot using and unfolding motion tabular origami. A squid-inspired jet propulsion mechanism is used to design an origami robot. The utilizes pulsed-jet through tubular structure, which could deform undulate provide for incorporated in stable body, while both forward steering are generated by structure undulating fins. An analytical model investigate capture relationship between motor's speed thrust...
