There is a fact that where surfaces are in contact with relative movement, there is also wear, with these aspects dealing the Tribology. There are other mechanical parts destroyed during functioning by the fatigue of the materials. Usually these two phenomena are studied separately. But there are mechanical systems where these two actions are joined into a single degradation event, leading to a shorter working time for the parts. The study of the tribo-wear as a simultaneous action with the material fatigue, leads...

The paper presents a neural network based methodology for prediction and optimization of internal combustion engine vehicles' fuel consumption, as a way to reduce air pollution. As it is well demonstrated lately, the engine fuel burning is one of the main factors that generate air pollution. Its impact on environment is rapidly increasing, following the increase of vehicles numbers. The best solution to reduce the air pollution is to use electric motor driven vehicles but these are still very expensive, with a low...
