In this research, an in-house code which uses the molecular dynamics method to study the flow of different nanofluids in the copper nanochannel and computes the thermo-physicals properties has been developed. The flow of nanofluids has been studied from hydro-thermally viewpoint and temperature jump at the wall has been applied. Parametric study to consider the effect of different parametric su...

Ultrasonic teclmiques have been used to directly and non-intrusively measure the circulation of free surface vortices. All experiments were performed in a vertical cylindrical tank with a central drain and a tangential inlet The circulation was measured on a closed triangular path by measuring the difference in upstream and downstream transit-times. Circulation was measured as a function of the...

purpose: to assess orbital color doppler ultrasonography (cdu) parameters of patients with manifest hyperopia in comparison to the emmetropes methods: forty eyes of 40 patients presenting with manifest hyperopia were included into the study. forty eyes of 40 emmetropes healthy volunteers also were examined as the control group. we have evaluated ophthalmic artery (oa), central retinal artery (c...

A volcanic record of geomagnetic field inclination for the past ~400 kyr at Hila, Hawaii, has been obtained from the 941.5 m of core recovered by the Hawaii Scientific Drilling Project. The analysis of 195 lava flows reveals six instances of near-zero inclination and two instances of fully negative inclination (reverse polarity) within an otherwise normal-polarity core. In particular, flow unit...

This paper examines the robustness of correspondence{based approaches to structure from motion. Unlike earlier studies it is proven in an algorithm{ independent way, that small absolute errors in image displacements cause absolute errors in rotational motion parameters signi cant enough to lead to large relative errors in the determination of environmental depth. Even if the exact motion parame...

In this article, we propose the use of the Mahalanobis depth to construct fully affine equivalent Theil-Sen estimators of parameters in a multiple linear model. Our construction includes the spatial depth-based Theil-Sen estimators as a special case. We exhibit that the efficiency of the proposed estimators relative to the least squares estimators increases with the number of parameters under i...

Although previous studies have proposed a variety of models to characterize diastolic pressure-flow relations, the models' ability to predict capacitance-free pressure-flow relations from dynamic information in individual studies has not been determined. This study tested the ability of a lumped RC model with pressure-dependent parameters to predict diastolic capacitance-free flow during maximu...

In this present work, The effect of input parameters viz. grinding wheel speed, work-piece speed, abrasive grain size, depth of cut, concentration of cutting fluid, and number of passes has been found on the surface roughness of cylindrical grinded AISI 4140 steel has been found. The other parameters like feed rate, diameter of work-piece, coolant flow rate, etc. are kept constant. Three levels...

We numerically and theoretically investigate the Boussinesq Eady model, where a rapidly rotating density-stratified layer of fluid is subject to meridional temperature gradient in thermal wind balance with uniform vertically sheared zonal flow. Through suite numerical simulations, we show that transport properties resulting turbulent flow are governed by quasi-geostrophic (QG) dynamics strongly...
