Anaerobic power in relation to field position of 90 Indian hockey players has been studied. These players included 10 goalkeepers, 16 backs, 20 half-backs and 44 forwards. The goalkeepers possess maximum and forwards possess minimum anaerobic power while in vertical velocity, the former are the fastest and the latter are the slowest. In body weight the backs are heaviest followed by half-backs,...

Albert and Miller (1997) performed an analysis of vertical velocity and angular momentum for single and double Axels. Their results indicate that both radial and tangential motion of the skater are critical to the generation of vertical velocity throughout the take-off of single and double Axels. In generating angular momentum during the take-off, the movement of the free leg was most critical....

The unsteady free convection flow between two long vertical parallel plates withvariable temperature and mass diffusion in the presence of the thermal radiation hasbeen presented. The governing dimensionless coupled linear partial differentialequations on the flow are solved by using the Laplace transform technique. TheExact solutions have been obtained for the fluid velocity, temperature and t...

We present laser-induced fluorescence (LIF) measurements of Xe II (4D7/2) in the FMT2 ion engine plume. Three 605.1 nm beams from a ring dye laser are focused through a single lens into a submillimeter interrogation volume, from which we collect LIF at 529.2 nm. Fourier-transform deconvolution of the LIF spectra returns ion velocity distribution estimates along the three laser beam directions. ...

The The kinematic interrelationships between the lower limbs, pelvis, trunk, and racquet in the performance of the high velocity tennis serve were investigated for 10 participants using a 12 camera opto-reflective Vicon MX system, operating at 250Hz. The average absolute peak racquet centre velocity was 34.0m∙s-1, which is comparable to previous studies using high performance players. Peak vert...

One of the signs of the cerebellar ocular motor syndrome is the inability to maintain horizontal and vertical fixation. Typically, in the presence of cerebellar atrophy, the eyes show horizontal gaze-evoked and vertical downbeat nystagmus. We investigated whether or not the cerebellar ocular motor syndrome also includes a torsional drift and, specifically, if it is independent from the drift in...

INTRODUCTION Vertical jumps have been fully studied during the last thirty years. Especially maximal vertical jumps used to be analyzed, which maximal vertical jump height was considered as the main factor of the performance. Maximal vertical jump height depends on effective energy, the sum of potential and “vertical kinetic energy” (i.e. kinetic energy due to vertical velocity) of the body mas...

Full waveform inversion (FWI) in transversely isotropic media usually requires abundant a priori information, like well data and smoothness assumptions, to make the FWI converge to a plausible solution. The proper model parameterization in transversely isotropic (TI) media with a vertical symmetry axis (VTI) can alleviate some of these limitations. Considering the limitations of our field data ...
