In this paper an analytical model for cold rolling of strip has been described. This model is developed based on the slab method of analysis and the hydrodynamic lubrication. The characteristics of rolling are obtained from the equations of equilibrium and the plate was allowed to strain harden assuming that the lubricant behaves as a Newtonian fluid. The shear stress to the plate is obtained b...

Muscle length changes of the lateral myotomal fast fibers of rainbow trout (Oncorhynchus mykiss) were measured using sonomicrometry during induced fast-starts. Simultaneous high-speed videography allowed for the analysis of midline kinematics to estimate the degree of muscle strain that occurs during body deformation. Comparison of these data was used to examine the phase relationship between l...

We present a two-dimensional grid-based hydrodynamic simulation of a thin, viscous, locally isothermal corotating disk orbiting an equal-mass Newtonian binary point mass on a fixed circular orbit. We study the structure of the disk aftermultiple viscous times. The binarymaintains a central hole in the viscously relaxed diskwith radius equal to about twice the binary semimajor axis. Disk surface...

Electron spin transport in a disordered ferromagnetic metal is theoretically studied from the hydrodynamic viewpoint, focusing on role of electron vorticity. The spin-resolved momentum flux density electrons calculated microscopically, taking account spin-orbit interaction and uniform magnetization, expression for motive force obtained as linear response to driving electric field. It shown that...

This article describes the design optimization of a hydrodynamic brake with an electrorheological fluid. The is performed on basis mathematical model geometry and brake’s electrical circuit. parameters models are selected based experimental tests prototype brake. Six different objective functions minimized during optimization. created taking into consideration following factors: braking torque,...

This paper describes and presents preliminary experimental results from a novel prototype energy scavenging system installed in a model 2m cylindrical Autonomous Underwater Vehicle (AUV). The system, which is based on control moment gyroscope (CMG) principles, utilises the gyroscopic response of a gimballed flywheel mounted within an AUV body to generate energy from the wave induced rotational ...

A statistical learning approach is presented to predict the dependency of steady hydrodynamic interactions thin oblate spheroidal particles on particle orientation and Reynolds number. The conventional empirical correlations that approximate such dependencies are replaced by a neural-network-based correlation which can provide accurate predictions for high-dimensional input spaces occurring in ...

introduction: some clinicians use a handheld screw driver instead of a torque wrench to definitively tighten abutment screws. the aim of this study was to compare the removal torque of one-piece and two-piece abutments tightened with a handheld driver and a torque control ratchet. methods: 40 iti implants were placed in acrylic blocks and divided into 4 groups. in groups one and two, 10 iti one...
