Wire-arc directed energy deposition (DED) of Al–Zn–Mg–Cu alloy faced a tough challenge because the occurrence crack and pore defects caused by high content alloying elements. Three cold metal transfer (CMT) arc modes were studied to fabricate components via wire-arc DED process, with aim optimizing process revealing action mechanism mode on microstructure mechanical properties. The effect CMT forming accuracy arc/droplet behaviors was investigated assistance microscope high-speed camera....
The pore defects and grain coarsening are the main reasons for performance deterioration in wire-arc directed energy deposition (DED) of ultra-high-strength aluminium alloy. In this study, experimentation numerical simulation were performed to investigate Zn element loss, bubble behaviours, microstructure effects wire feeding rate (WFR) DED 7075 results suggested that both Zn-bubble H-bubble did not flow upward directly, but flowed with molten pool convection. A low WFR decreased sources...
An improved cross-entropy (CE) method assisted with a chaotic operator (CGSCE) is presented for solving the optimal power flow (OPF) problem. The introduction of helps to enhance exploration capability popular approach while global best solution preserved. To handle constraints in flow, an efficient constraint handling technique no parameter adjustment also introduced. tested on both IEEE-30 bus system and IEEE-57 different objective functions verify its effectiveness comparison few other...
The influence of electrode positive/electrode negative (EP/EN) ratio on cold metal transfer advance-based wire arc additive manufacturing (WAAM) process for Al–Zn–Mg–Cu alloy was studied in this paper. stability investigated via analysing electrical waveforms and arc/metal images concurrently. A high EP/EN (≥ 13:7) beneficial to decrease abnormal long wait phase duration current spatter droplet, which improved the WAAM process. forming accuracies samples increased first then decreased with...
Recently, reinforcement learning (RL) algorithms have demonstrated remarkable success in complicated behaviors from minimally processed input. However, most of this is limited to simulation. While there are promising successes applying RL directly on real systems, their performance more complex systems remains bottle-necked by the relative data inefficiency algorithms. Domain randomization a direction research that has impressive results using control robots. At high level, domain works...
The construction industry is one of the most dangerous industries with grave situation owing to high accident rate and mortality rate, which accompanied a series security management issues that need be tackled urgently. unsafe behavior workers critical reason for incidence safety accidents. Affective Events Theory suggests individual emotional states interfere decisions behaviors, means can significantly influence workers' behaviors. As complexity site environment lack attention emotions by...
Reinforcement learning (RL) has traditionally been understood from an episodic perspective; the concept of non-episodic RL, where there is no restart and therefore reliable recovery, remains elusive. A fundamental question in RL how to measure performance a learner derive algorithms maximize such performance. Conventional wisdom difference between average reward received by maximal long-term reward. In this paper, we argue that if total time budget relatively limited compared complexity...
Objective To explore the feasibility of single micro extrusion 3D printing method for skin tissue. Methods Fibroblasts were isolated and cultured from human dermis identified by immunofluorescence staining. Fibroblasts HaCaT cells used as seed cells. Gelatin, hyaluronic acid fibrinogen to form scaffolds. HE staining observe cell distribution printed skin. The viability in tissue was detected living/dead kit. Toluidine blue penetration assay detect barrier function...
