The focus of this paper is on estimating the stress concentration factor circular hollow section KK-joints with different geometric parameters and subsequently assessing effectiveness carbon fiber-reinforced polymer (CFRP) wrapping for repairing joints cracks. Different parameters, such as θ (brace inclination angle), γ (the ratio outer diameter to wall thickness chord), τ brace were studied investigate changes in using numerical simulation. results indicated that was most sensitive θ,...

In this study, 90 finite-element models are used to explore the behaviour of fibre-reinforced polymer (FRP) reinforced joints under combined in-plane bending (IPB) and axial load (AX). The effects joint geometry, FRP layer count, AX levels chord or brace considered. Three typical failure modes observed: plastic failure, buckling failure. Increasing number layers can ensure that is chord-related in a ductility manner rather than unexpectedly brace-related brittle Depending on stress...

<p style='text-indent:20px;'>In considering route optimization from multiple distribution centers called depots via some intermediate facilities satellites to final customers with commodities request, we introduce the Multi-Commodity Two-Echelon Vehicle Routing Problem Satellite Synchronization (MC-2E-VRPSS). The MC-2E-VRPSS involves transportation on first echelon and deliveries second echelon. integrates satellite synchronization constraints time window for two-echelon network aims...

In this work, we report the bidirectional photoresponse of carbon-based graphdiyne/graphene (GDY/Gr) heterojunction photodetector toward optical logic gates. The uniform GDY film was facilely grown on surface Gr serving as template. Under mV-level bias, resultant Au/GDY/Gr/Au devices manifest to a broad wavelength range with rapid response time, namely, positive and negative under respectively. It can be understood from viewpoint divergence coincidence between in-plane external potential....

In this work, we report a high-performance photodetector based on perovskite CH3NH3PbBr3 quantum dots (QDs) films with configuration of Au/CH3NH3PbBr3 QDs-Al2O3-indium tin oxide/Au as bioinspired photoelectric synapse. The uniform QDs thin film is fabricated by electrodepositing solution and exhibits favorable long-term stability at ambient. By inserting an Al2O3 film, the dark current photodetectors significantly suppressed result blocking effect, accompanied enhanced ON/OFF ratio....

Time series forecasting (TSF) is crucial in various fields and has gained extensive research. However, most studies are conducted based on TS data with scale homogeneity. This paper proposes a self-Adaptive Scale-handling (AS) module to improve the performance of heterogeneity. It consists scaling selection calibrating. We first calculate priori factors each time variable then selectively calibrate through neural networks. Hence, we can TSF algorithms by reducing restoration errors. validate...
