To maintain the stability trajectory of vehicles under critical driving conditions, anti lock-anti skid controllers, consisting of four anti-lock sub-controllers for each wheel and two anti-skid sub-controllers for left and right pair wheels have been separately designed. Wheel and body systems have been simulated with seven degrees of freedom to evaluate the proper functioning of controllers. ...

Due to its good cutting performance in titanium alloy machining, integral end mills are more and used machining aero-engine impeller blades. The tool spiral groove plays the role of chip acceptor removal, accuracy parameters has an important effect on performance. In grinding process groove, wheel’s external is mainly involved task. wear degree related time times wheel, wheel will lead change g...

In this paper we present new ESO/VLT FORS1 and ISAAC images of the fields around eight gravi-When available and deep enough, HST/WFPC2 data were also used to infer the photometric redshifts of the galaxies around the quasars. The search of galaxy overdensities in space and redshift, as well as a weak-shear analysis and a mass reconstruction are presented in this paper. We find that there are mo...

The purpose of this paper is to develop a new technology for controlling the quenching deformation light cast aluminum alloy wheels. First, based on existing wheel heat treatment process, gas–liquid–solid multi-phase flow coupling model was established through ANSYS Workbench platform analyze gas–liquid phase change, exchange surface and characteristics during process immersion into water. resu...

HYDROGEN interaction with amorphous alloys has Ribbons (,25-mm thick) of amorphous Fe80B11Si9 were been studied extensively due to both scientific and technoused for this research. The ribbons were produced by planarlogical interest. In the framework of a more comprehensive flow casting and were kindly supplied by AlliedSignal Inc. investigation of hydrogen interaction with amorphous and (Parsi...

Bottom-up gated filling system was performed to produce worm wheel through a sand casting of zinc alloy. It symmetrical design in which two wheels were cast at once, the erected direction gravity and had gating molten alloy poured from below. The recovery rate designed mold cavity 60%. Casting analysis check that sequentially filled without turbulent flow as passed gate. Though speed initially ...

BACKGROUND Animal and human studies suggest that stress experienced early in life has detrimental consequences on brain development, including brain regions involved in cognitive function. Cognitive changes are cardinal features of depression and posttraumatic stress disorder. Early-life trauma is a major risk factor for these disorders. Only few studies have measured the long-term consequences...
