We consider three-dimensional hydraulic jumps (shocks) propagating along boundaries in rotating fluids. This study is motivated by earlier work (Fedorov & Melville 1995), which dealt with the evolution to breaking of nonlinear Kelvin waves. We obtain the jump relations and derive an evolution equation for the jump as it propagates along the boundary. It is shown that after some initial adjustme...

Vertical jump height is frequently used by coaches, health care professionals, and strength and conditioning professionals to objectively measure function. The purpose of this study is to determine the concurrent validity of the jump and reach method (Vertec) and the contact mat method (Just Jump) in assessing vertical jump height when compared with the criterion reference 3-camera motion analy...

BACKGROUND Patterned electrical neuromuscular stimulation (PENS) uses the electrical stimulation of sensory and motor nerves to achieve a skeletal muscle contraction using an electromyogram-derived functional pattern. PENS is used extensively for neuromuscular reeducation and treatment of muscle disuse atrophy. PURPOSE To explore the effectiveness of PENS as applied to the quadriceps muscles ...

The purpose of this study was to test the effect of knee-to-feet jump training on power and vertical jump height. Twenty-one varsity athletes from power-emphasized sports were paired and randomly placed in the control or experimental group. All subjects completed preand post-tests of vertical jump height, knee-to-feet jump height, and 2 repetition maximum hang clean. The experimental group comp...

Ankle sprain is one of the most common sport injuries in lower extremities. It frequently occurs in landing phase when athletes perform jumping. The counter movement jump and straddle jump are common jumping strategies often used in baseball and volleyball games. Recurrent ankle sprain frequently leads to a chronic disability, the functional instability. The purpose of this study was to investi...

The records maintained by Jump Lists have the potential to provide a rich source of evidence about users’ historic activity to the forensic investigator. The structure and artifacts recorded by Jump Lists have been widely discussed in various forensic communities since its debut in Microsoft Windows 7. However, this feature has more capabilities to reveal evidence in Windows 10, due to its modi...
