Shear wave measurements for the determination of tissue elastic properties have been used in clinical diagnosis and soft tissue assessment. A shear wave propagates as a transverse wave where vibration is perpendicular to the wave propagation direction. Previous transverse shear wave measurements could detect the shear modulus in the lateral region of the force; however, they could not provide t...

Seawalls are built for Protecting of beaches against waves and preventing the progression of water to the beach. For a proper understanding about these constructions, a suiTable information about applied loads on these constructions should be existed. One of the important load that applied on these constructions is sea wave. Others loads are included: weight force of the walls, weight force of ...

The present investigation is concerned with the propagation of waves at an imperfect boundary of heat conducting elastic solid and micropolar fluid media. The amplitude ratios of various reflected and transmitted waves are obtained in a closed form due to incidence of longitudinal wave (P-wave), thermal wave (T-wave), and transverse wave (SV-wave). The variation of various amplitude ratios with...

Telerobotics has long struggled to provide realistic force feedback to a user, especially across substantial time delays. Wave variable based controllers provide stable force reflection at frequencies up to a few hertz for typical communication delays; however, the bandwidth of human perception extends to a thousand hertz. In this paper we aim to improve the user’s perception by constructing a ...

Through the use of the well-known Morrison/Wheat/Erkut ice hockey model, we demonstrate that even optimal solutions may be open to question. Based on the assumptions which are made to estimate data values, optimal solutions may vary among decision makers. We also note that under any reasonable set of assumptions, hockey coaches wait too long before pulling their goalies. tion made by Erkut is a...
