When using point measurement for environmental or sediment laden flows, there is well-recognised risk not having aligned measurements that causes misinterpretation of the measured velocity data. In reality, these kinds mismeasurement mainly happen due to bed orientation caused by complexity its determination in natural especially bedload rough flows. This study proposes a novel realignment meth...

Motivated by the measured velocity profile of M87 jet using KVN and VERA Array (KaVA) Park et al. indicating that starting position acceleration is farther from central engine than predicted in general relativistic magnetohydrodynamic simulations, we explore how to mitigate apparent discrepancy between simulations KaVA observation. We use a semi-analytic model proposed Tomimatsu Takahashi. cons...

A novel methodology, based on the use of phosphorescence imaging, is applied to determine the local through-thickness velocity profile of lubricant in an elastohydrodynamic contact. The technique has spatial and temporal resolutions of 40 μm and 340 μs respectively and thus allows lubricant rheology to be investigated at conditions close to service conditions. The capability of the newly-develo...

The present study examined the rheological blood velocity profile in the conduit femoral artery during rhythmic muscle contractions at different muscle forces. Eight healthy volunteers performed one-legged, dynamic knee-extensor exercise at work rates of 5, 10, 20, 30, and 40 W at 60 contractions per minute. The time and space-averaged, amplitude-weighted mean (V(mean)) and maximum (V(max)) blo...

Instantaneous velocity of pulmonary artery blood was measured using a thin-film resistance anemometer mounted on a hypodermic needle. Studies were performed, at thoracotomy, in five dogs and five patients. Instantaneous blood velocity was recorded at several sites across die transverse axis of the main pulmonary artery to determine the shape of the velocity profile. We found the velocity profil...

We perform experimental measurements of the instantaneous velocity profile of the flowing layer during granular avalanches. In the pile depth, the velocity profile follows a pure exponential decrease in contrast with steady flows that are known to exhibit a well developed upper linear part. The velocity profile in the pile width is a plug flow with two exponential boundary layers at the walls. ...

detection of subsurface structures by means of gravity method can be used to determine mass distribution and density contrast of rock units. this distribution could be detected by different geophysical methods, especially gravity method. however, gravity techniques have some drawbacks and can't be always successful in distinguishing subsurface structures. performance of the gravity technique co...

We construct a mass model for the spiral lens galaxy 2237+0305, at redshift zl=0.04, based on gravitational-lensing constraints, HI rotation, and new stellarkinematic information, based on data taken with the ESI spectrograph on the 10m Keck-II Telescope. High resolution rotation curves and velocity dispersion profiles along two perpendicular directions, close to the major and minor axes of the...
