For the best performance and longer duration of devices or elements that participate in a mechanical energy transport system, they require an adequate lubrication process in the areas exposed to friction: bearings, gears, cylinder-piston, etc. This process is very important for the optimal functioning of the system, since it reduces repair costs and unscheduled failures. One of the frequent problems of poor lubrication is generated by the Cavitation phenomenon, for this reason it is important to study its effects under operating conditions. In the present work, the formulation and numerical simulation of Cavitation in bearings is carried out, considering the variation of the viscosity of the lubricant in relation to the pressure and the distribution space. In other works carried out on this phenomenon, it is mentioned how complex it would be to develop a numerical process in a two-dimens...

The present work is a sample of application of the measure concepts and dimension of geometry fractal in the simulation of the process of fragmentation applied to the study of the seismological behavior in Perii. In this investigation it is looked for to relate the concepts of statistical distribution and fractal dimension; in the purpose of being able to express justifiably in a realler way, the behavior of magnitude frequency and latitude of seismic occurrence.
