generally, fatigue failure in an element happens at the notch on a surface where the stress level rises because of the stress concentration effect. the present paper investigates the effect of a notch on the fatigue life of the hsla100 (­high strength low alloy) steel which is widely applicable in the marine industry. tensile test was conducted on specimens and mechanical properties were obtain...

Throughout the spring 2013 semester I continued to work on the frictional model for a rotating lifter system. The previous frictional model assumed friction to be a constant, which only showed to be valid for sufficiently small values of . Now it has been determined that friction is proportional to the velocity, which is valid through all angular displacements. Allowing the lifters to move thro...

In order to study the effect of low frequency weak magnetic field on the cardiovascular system through the central nervous system, this paper design the experiment that is using a rotating magnetic field acts on the cerebral cortex, the different frequency when different parts of the brain, collecting and analysis ECG and blood pressure signal, and discussing the effect of low frequency rotatin...
