The changes that occur in all of the motor unit recruitment following the central and peripheral lesions of motor nerves can be effective on individual's disability. Following the low back pain (L.B.P) with any known cause, the effective role of muscles in providing postural or dynamic stability will be reduced. Today in rehabilitation of these patients, except of medical treatment for reductio...

In this paper we have studied the effect of free convection on the heat transfer and flow through variable porous medium which is bounded by two vertical parallel porous plates. In this study it is assume that free stream velocity oscillates with time about a constant mean. Periodic temperature is considered in the moving plate. Effect of different parameters on mean flow velocity, Transient ve...

We demonstrate a three-step method for estimating time-resolved velocity fields using time-resolved point measurements and non-time-resolved particle image velocimetry (PIV) data. First, we use linear stochastic estimation to obtain an initial set of time-resolved estimates of the flow field. These initial estimates are then used to identify a linear model of the flow physics. The model is inco...

the application of nmo (normal moveout) has been recognized as an effective method of generating quasi-zero-offset traces in traditional common-midpoint processing. artifacts of the nmo method relate to the nmo-stretch effects. conventional application of normal-moveout correction to a common-midpoint (cmp) reflection generates a stretch that increases with offset and decreases with zero-offset...

abstract: in the paper of black and scholes (1973) a closed form solution for the price of a european option is derived . as extension to the black and scholes model with constant volatility, option pricing model with time varying volatility have been suggested within the frame work of generalized autoregressive conditional heteroskedasticity (garch) . these processes can explain a number of em...

Introduction: Orexin A is a hypothalamic neuropeptide, widely distributed in many parts of the central nervous system and perhaps due to this reason, this neuropeptide is involved in many physiological functions. The purpose of this study was to determine the effect of lateral cereberoventricular injection of orexin A on distance, velocity and swimming time in rats. The results were analyzed...
