Electro-oculographic recordings were obtained from 11 patients with Huntington's disease. Significant reduction of saccadic velocity was constantly found. In all the patients vertical saccades were much more impaired than horizontal. When present, vertical saccades showed long latency, low amplitude, low velocity, and disturbances related to blinking. Following movements were jerky, and ability...

Use the Spur dike as one of the easiest ways to protect the costal of the river has always been of interest to River engineers.The aim of this study was numerical investigate, the effect of distance and angle of the spur dikes parameters  on the pattern of distribution of average velocity  and the location of maximum velocity position at a mild 90 degree bend. For this purpose used ANSYS CFX so...

Staggered vertical nests have been developed, coupled with the WRF innermost nests. This methodology is applied to the high resolution simulations of field data from the T-REX Campaign of measurements (Terrain-induced Rotor Experiment), Owens Valley, CA, 2006. Our real case WRF simulations are based on initial and boundary conditions from both high resolution T799 L91 ECMWF analysis data and GF...

[1] Velocity, temperature, and specific humidity data collected by aircraft at 20-Hz resolution are analyzed for stability and turbulence parameters. Over 100 vertical profiles (mostly over the ocean) with a total of over 300 km in vertical airspace sampled are used. The compiled statistics show that anisotropy in the velocity fluctuations prevail down to the smallest spatial separations measur...

Nystagmus induced by off-vertical axis rotation (OVAR) about a head yaw axis is composed of a yaw bias velocity and modulations in eye position and velocity as the head changes orientation relative to gravity. The bias velocity is dependent on the tilt of the rotational axis relative to gravity and angular head velocity. For axis tilts <15 degrees, bias velocities increased monotonically with i...

We have shown in the previous lectures that the −vU ′ term in the u equation, that is ∂tu = −vU ′ + · · · , is the key term leading to momentum transport −uv ∼ vvU ′t and perturbation energy production −uv U ′ ∼ vv(U ′)2t > 0. This term is the redistribution of streamwise velocity that releases energy from the background shear to enable bifurcation to turbulent flow. However, in shear flows we ...

The temperature, velocity, and concentration distributions were measured in boundary layers adjacent to heated vertical polymethyl methacrylate (PMMA) and wood (Southern Pine) surfaces, and next to a heated, vertical, sintered bronze plate through which propane was injected. The temperature, velocity, and concentration were measured as functions of position and time using thermocouple probes, f...

this paper addresses the combined effects of couple stresses, thermal radiation, viscous dissipation and slip condition on a free convective flow of a couple stress fluid induced by a vertical stretching sheet. the cogley- vincenti-gilles equilibrium model is employed to include the effects of thermal radiation in the study. the governing boundary layer equations are transformed into a system o...
