Dynamics of the long jump.

The relationship between selected biomechanical and technical factors and success criteria in long jump take-off performed by elite athletes

Take-off is the critical phase of the long jump event. The aim of this study was to explore the relationships between different variables and success in take-off. 37 trials performed by 8 long jumper, participants in fourth indoor Asian senior athletics championships held in Tehran, with personal best average of 7.68±0.28 meter were recorded at 300 Hz. Five speed-related, five technical and ...

The Evaluation of Changes in the Center of Pressure in Different Types of Defense on the Professional Volleyball Players

Objective The purpose of the present study was to investigate the center of pressure (CoP) movements during the jump-landing while defending on the net in professional volleyball players and compare it with beginner volleyball players. Methods In this research, 10 professional volleyball players and 10 beginner volleyball players voluntarily participated in this study. The CoP movements in ant...

Option pricing under the double stochastic volatility with double jump model

In this paper, we deal with the pricing of power options when the dynamics of the risky underling asset follows the double stochastic volatility with double jump model. We prove efficiency of our considered model by fast Fourier transform method, Monte Carlo simulation and numerical results using power call options i.e. Monte Carlo simulation and numerical results show that the fast Fourier tra...

Long Range Corrections to the Vapor-Liquid Equilibrium and Surface Tension of Methane with NVT Molecular Dynamics Simulations

Extreme News Events, Long-memory Volatility, and Time Varying Risk Premia in Stock Market Returns

This paper proposes a new GARCH-jump in mean model to test the presence of time varying risk premia associated with normal and extreme news events. The model allows for a dynamic jump component with autoregressive jump intensity, long-range dependence in volatility dynamics, and a volatility in mean structure separately for the normal and extreme news events. The results show significant jump r...

Investigation into the Effects of Nanoparticle Size and Channel Depth on the Thermophysical Properties of Water Nanofluids in the Nanochannel Using Molecular Dynamics Simulation

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...
