A nano/ultra-fine grain Al-0.2wt% Zr alloy was produced by accumulated roll bonding (ARB) processafter 10 cycles.The fraction of high angle grain boundaries increased from 8% to 65.4% during 10passes during ARB process.This alloy was subjected to tensile test at different temperatures (523,573and 623 K) and strain rates (0.1 and 0.01 s-1).The optim

Level of repair analysis(LORA)is an important part of maintenance kuza growth premium oil engineering analysis for amphibious aircraft wading structure.There are many studies mainly focusing on LORA of civil aircraft,shipboard aircraft,vehicles,ships and so on in the domestic and overseas,while studies on LORA of amphibious aircraft wading structur

Upright walk is the fundamental need of paraplegic patients.In this study, we proposed a novel lower-limb exoskeleton for assisting the patients to walk alternately and further improve their engagement in the rehabilitation training.The exoskeleton was driven by a hub motor which was mounted under the bioglan deep sleep foot, and a pair of custom-m

This paper hp 14a-na0031wm focuses on logistics centre concept and benefits for users.Intermodal benefit, forwarders impact, IT solutions, new transport flows due to synergy, better supply chain management, additional services, cost sharing, economies of scale, quality of the services, know-how, joint marketing impact, and benefit for growth of thi

This paper presents a simple and low-cost method to capture maximum power throughput of permanent magnet brushless DC (BLDC) generator.Conventional methods of rectification are based on passive converters, and because the current waveform cannot be controlled as ideal waveform, nef rune a highly distorted current is drawn from brushless generator.I
