background hamstring muscles play an important role in functional activities and relaxation and most people around the world suffer from the shortened muscles. different methods of repairing were suggested and there were disagreements with regard to determination of one technique with high efficiency. objectives this study aimed to introduce more effective method, either a static stretch or hol...

Most motion compensation methods dealt with in the literature make strong assumptions about the smoothness of the underlying motion eld. For instance, block-matching algorithms assume a blockwise-constant motion eld and are adequate under translational motion models; triangle motion compensation assumes a piecewise-planar motion eld, and this model captures zooming, warping and rotational motio...

This study evaluates the role of shock wave motion on the instability of the plume exiting an over-expanded, convergent-divergent nozzle. An array of wall pressure transducers was used to track the position of the shock in time, and a Pitot probe was used to obtain simultaneous measurement of the total pressure fluctuations at various points in the jet that emerges from the separation shock. An...

Tension-Leg Platform (TLP) is a vertically moored floating structure. The platform is permanently mooredby tendons. Surge equation of motion of TLP is highly nonlinear because of large displacement and it should be solved with perturbation parameter in time domain. This paper compare the dynamic motion responses of a TLP in regular sea waves obtained by applying three method in time domain usin...

This paper describes a video coding algorithm that combines new ideas in motion estimation wavelet l ter design and wavelet based coding techniques A mo tion compensation technique using image warping and over lapped block motion compensation OBMC is employed to reduce temporal redundancies in a given image sequence This combined motion model has the advantage of repre senting more complex moti...
