Most research on wireless power transfer (WPT) has been focused on how to achieve a high-efficiency power transfer. Our study found that under the impedance matching for achieving maximum WPT efficiency, the power transferred to the load cannot reach the maximum when a WPT system is supplied by an AC voltage source with constant amplitude. However, the load power or the voltage across the load ...

Experimental test are carried out on a semi-heavy duty Motorsazan MT4.244 agricultural engine at various loads in order to evaluate performance and emissions of DI diesel engine using the blends of diesel fuel with 5%, 10%,15%,20% , 30%(by volume) Castor oil and pure diesel fuel separately. The result show that maximum decreasing of PM emission is 73.2% and is observed in B15 at 50%load and the...

High Performance Fiber Reinforced Cementitious Composite (HPFRCC) materials exhibit strain hardening behavior with multiple cracking under tensile loading. In this paper, experimental and parametric studies are performed to assess the influence of using HPFRCC material instead of normal concrete in reinforced concrete beams. After calibrating the experimental results, the analytical results inc...

The present contribution deals with the numerical modeling of railway track-supporting systems-using coupled finite-infinite elements-to represent the near and distant field stress distribution, and also employing a thin layer interface element to account for the interfacial behavior between sleepers and ballast. To simulate the relative debonding, slipping and crushing at the contact area betw...

The objective of this study was to investigate the effects of conventional lubricants including a new candidate lubricant on binary direct compression mixtures. Magnesium stearate (MGST), stearic acid (STAC), glyceryl behenate (COMP) and hexagonal boron nitride (HBN) were tested. The binary mixtures were 1:1 combinations of spray dried lactose (FlowLac 100), dicalcium phosphate dihydrate (Emcom...

A centralized scheduler must assign tasks to servers, processing on-line a sequence of task arrivals and departures. Each task runs for an unknown length of time, but comes with a weight that measures resource utilization per unit time. The response time of a server is the sum of the weights of the tasks assigned to it. The goal is to minimize the maximum response time, i.e., load, of any serve...

Abstract During installation of driven or jacked piles in sand, particle crushing occurs a region below the base these piles. Quantification degree and extent during driving jacking sand is necessary to improve current design methods. To study effects on capacity uniform silica samples, model pile was tested half-cylindrical calibration chamber with transparent observation windows its front wal...

1. New growth in cutaneous mechanosensory neurones elicited by axotomy or axon crush was studied using intracellular injection of horseradish peroxidase at different times after the lesion, ranging from a few days to over a year. 2. Cutting or crushing major, large-calibre axon branches of mechanosensory neurones elicits sprouting of new processes, either centrally within the ganglion neuropile...

This wide-ranging, omnivorous lizard of Australia has a very complex adductor muscle mass, with fibers differing in length by a factor of three and in insertion angle by 90 degrees. Stimulated muscles produce maximal moment with the mouth nearly fully open. The opening mechanism appears to involve only simple rotation and no translation of the mandible. EMGs indicate that the entire mass is act...

The worldwide mining industry consumes a vast amount of energy in reduction fragment size from to mineral processing with an extremely low-energy efficiency, particularly ore crushing and grinding. Regarding such situation, this article describes the effects rock fragmentation by blasting on consumption, productivity, minerals’ recovery, operational costs whole chain processing, sustainability ...
