in this paper, multi-objective uniform-diversity genetic algorithm (muga) with a diversity preserving mechanism called the ε-elimination algorithm is used for pareto optimization of 5-degree of freedom vehicle vibration model considering the five conflicting functions simultaneously. the important conflicting objective functions that have been considered in this work are, namely, vertical accel...

In track-oriented road cars with electric powertrains, the ability to recuperate energy during track driving is significantly affected by frequent interventions of antilock braking system (ABS), which usually severely limits regenerative torque level because functional safety considerations. high-performance vehicles, when controlling an active rear wing maximize brake regeneration, it unclear ...

Abstract Due to the bus characteristics of large quality, high center gravity and narrow wheelbase, research its yaw stability control (YSC) system has become focus in field vehicle dynamics. However, tire nonlinear mechanical properties effectiveness YSC are not considered carefully current research. In this paper, a novel adaptive nonsingular fast terminal sliding mode (ANFTSM) scheme for is ...

in the present study, development of new asbestos-free brake pad using lingo-cellulosic fibers and nano aluminum oxide particles was investigated. variable factors were the type of lignocellulosic materials (jute, bagass and rice husk) and the size of aluminum particles (nano and micron). these newly formulated brake pads have been tested under the grey cast iron disc. friction coefficient and ...

a few dozen neuroscientists, psychiatrists, and drug-company executives gathered in a hotel conference room in Brussels to hear some startling news. It had to do with a class of drugs known as atypical or second-generation antipsychotics, which came on the market in the early nineties. The drugs, sold under brand names such as Abilify, Seroquel, and Zyprexa, had been tested on schizophrenics in...

Abstract The recent debate regarding the eligibility of converts to Judaism ( gerim ) sit on a beṯ din – judicial panel is unexpected. In 19th century, when rabbis first begin answer questions about whether or not may serve panels for conversion other potential , tone consistently one surprise: was an obvious yes. later reflections, however, shifts, with increasing demands definitive proof that...

polymeric yarns for reinforcing cement composites have got great interest in all over the world. in this research the performance of bonding between nylon tire cord grad yarns, and one kind of cement composite called fine grained concrete was studied. two kinds of nylon cord yarns, nylon 6 and 66, with different finesse were selected. the durability of yarns with time in alkaline media was inve...

The viscoelastic effect of rubber material on creation of rolling resistance is responsible for 10-33% dissipation of supplied power at the tire/road interaction surface. So, evaluating this kind of loss is very essential in any analysis concerned with energy saving. The transient dynamic analysis for including the rolling effects of the tire requires long CPU time and the obtained results are ...

Trucking fleets and owners of commercial vehicles utilize both new and retread tires on their vehicles in the United States. Retread tires are used primarily for the cost advantage they provide over a similar new tire. Despite the advantages that retreaded tires may bring, public perception is that retread tires are less safe than new tires as evidenced by the amount of tire debris frequently f...
