Several past studies developed acceleration/deceleration rate models as a function of single explanatory variable. Most them were spot speed with speeds measured at specific locations on curves (usually midpoint the curve) and tangents to determine acceleration deceleration rates. Fewer adopted an estimated value 0.85 m/s2 for both rates while approaching departing curves, respectively. In this...

Computer simulations and scale model drop tests are performed to evaluate the splashdown loads of a capsule in nonaqueous liquids, in anticipation of the descent of the ESA Huygens probe on Saturn's moon Titan which may have lakes and seas of liquid hydrocarbons. Deceleration profiles in liquids of low and high viscosity are explored, and how the deceleration record may be inverted to recover f...

In this paper, we investigate the quintessence model with a minimally coupled scalar field in the context of recent supernovae observations. By choosing a particular form of the deceleration parameter q , which gives an early deceleration and late time acceleration for dust dominated model, we show that this sign flip in q can be obtained by a simple trigonometric potential. The early matter do...

We present the results of numerical simulations of shock wave-driven jets in the solar atmosphere. The dependence of observable quantities like maximum velocity and deceleration on parameters such as the period and amplitude of initial disturbances and the inclination of the magnetic field is investigated. Our simulations show excellent agreement with observations, and shed new light on the cor...

We construct a three-dimensional, fully relativistic numerical model of a universe filled with an inhomogeneous pressureless fluid, starting from initial data that represent a perturbation of the Einstein-de Sitter model. We then measure the departure of the average expansion rate with respect to this homogeneous and isotropic reference model, comparing local quantities to the predictions of li...

The purpose of this study was to examine spatiotemporal parameters of the walk-to-run transition (WRT) and run-to-walk transition (RWT) when speed is altered with different constant accelerations. Twenty women (height: 168.9+/-3.36cm) performed three accelerations (0.05, 0.07 and 0.1ms(-2)) and three decelerations (-0.05, -0.07 and -0.1ms(-2)) on a motor-driven treadmill. The transition step in...
