This paper is focused on the performance of worm gears influenced by the position of the contact pattern. By decreasing in size of the contact pattern area the lubricant film thickness between worm and worm wheel teeth will be decreased and lubricant temperature as a criterion for worm gears performance will be increased. In this experiment by designed tests, the effect of Contact Pattern Position of the Worm Wheel Teeth on the Lubricant Temperature behavior had been investigated. By considering the performed studies on statistical results of the amount of percentage of contact area in every tooth of under experiment …

The theft of property and its associated impact effects many parts of society. For example, a considerable amount of resources are expended in trying to reduce property theft, as such crime engenders both a financial and emotional impact (Grabosky, 1995, p. 1) on those involved. Factors such as fear of crime, increased insurance premiums and victimization are all outcomes of property crime. Much of the past research has focused on the mitigation of such crimes, collectively termed as ‘crime prevention’. Crime prevention are “any actions designed to reduce the actual level of crime and/or the perceived crime” (S.P. Lab, 2010, …

This study presents an experimental validation of a model theory for determining the relationship between a nondestructive measurement parameter and a property of interest. It was found that the reciprocal of the peak envelope amplitude of the Barkhausen emission voltage follows a linear relationship with stress. A linear relationship between stress and the reciprocal of the root mean square voltage was also obtained. These observations represent an important step towards improving the use of Barkhausen signals for magnetic non-destructive evaluation of stress as a function of depth in ferromagnetic load bearing structures.
