Abstract: A parametric investigation of the thoracic injury potential of basic taekwondo kicks was conducted through the use of computer simulations. Linkage-based models were employed to simulate the ...

Abstract: Laser Doppler Vibrometry is presented as an effective method of measuring surface profiles of rolling contact bearing balls. An experimental setup and signal processing algorithm are used to ...

Abstract: A principal source of vibration in permanent magnet motors and generators is the induced stress from the rotating permanent magnets. The harmonic content of this forcing function may excite ...

Abstract: A principal source of vibration in permanent magnet motors and generators is the induced travelling forces from the rotating permanent magnets acting on the stator. The form of the magnetic ...

Abstract: A ski release binding releases the ski boot from the ski for loading environments potentially injurious to the lower extremity. The concept of using a model reference adaptive control system ...

Abstract: Percussive excavation is researched as a viable technology to reduce the shear strength of the dry lunar soil simulant JSC-1A. Experimental tests were conducted in a percussive and quasi-static test bed, which used a replica ...
