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....

Introduction: The objective of this study was to compare two methods of dry needle treatment in active trigger points of Gastrocnemius muscle on pain and height jump in non-professional athletes. Materials and Methods: Forty male athletes were selected with active trigger points in each Gastrocnemius muscle. Relatively, subjects were assigned randomly in two conventional dry needle piston metho...

Objective: The aim of this study was to investigate the relationship between isokinetic relative torques of hip, knee and ankle joints and the height of guide leg jump in young men. Methods: 27 college male athletes with mean age of 25±3.5 years, height 178.5±7.8 cm and weight of 75.7±10.7 kg voluntarily participated in this study. Isokinetic torque of hip, knee and ankl...

This paper presents the results of an analytical and experimental study on the characteristics of hydraulic jump in a triangular channel. The analytical consideration is based on the momentum conservation law for the upstream and downstream sections of the jump. The experiments were carried out in a triangular channel of glass side walls with the vertex angle of 94.4°. A wide range of discharge...

Purpose: This study aimed to investigate the effect of genu varum abnormality on the activity of the anterior leg calf muscle during single-leg jump-landing task.  Methods: A total of 28 male students of Physical Education (Mean±SD age: 21.53±1.65 y, weight: 66.67±7.15 kg, height: 173.38±4.54 cm) were assigned into the genu varum (n=14) and normal knee (n=14) groups. Their level of activity of...

We derive closed formulas for the prices of European options andtheir sensitivities when the underlying asset follows a double-exponentialjump diffusion model, as considered by S. Kou in 2002. This author hasderived the option price by making use of double series where each termrequires the computation of a sequence of special functions, such thatthe implementation remains difficult for a large...

Abstract We develop a novel nonlocal model of dislocations based on the framework peridynamics. By embedding interior discontinuities into constitutive law, displacement jump in Volterra dislocation is reproduced, intrinsic singularities classical elasticity are regularized, and surface effect previous peridynamics models avoided. The extended embedded discontinuity overcomes unphysical dissipa...

<p style='text-indent:20px;'>The present article studies geometric step options in exponential Lévy markets. Our contribution is manifold and extends several aspects of the option pricing literature. First, we provide symmetry duality relations derive various characterizations for both European-type American-type double barrier options. In particular, are able to obtain a jump-diffusion d...

results all variables reached a peak at 1 minute post-jump. salivary alpha-amylase, galvanic skin responses and heart rate did not return to basal value at 90 minutes post-jump, while cortisol returned to basal value at 90 minutes post-jump. conclusions this evidence indicates that parachute jumping is accompanied by a dissociation of sns and hpa response patterns in novice parachutists, showin...
