Research ArticleOpen accessIn the abstractINVESTIGATION ON THE DIAGNOSIS OF SIMPLE AND COMBINES MECHANICAL FAULTS IN ASYNCHRONOUS MOTOR BASED ELECTRIC DRIVESBouras A. Karim, Bouras Slimane, Hadjadj A. Elias et al.In this study, the problems of mechanical unbalance, parallel and angular misalignments and their combinations are analyzed experimentally. Such frequent defects in the drives mainly in the major powers are also responsible for the bearings degradation. However, they have not raised the attention of researchers, given the complexity of their modeling. The combination of the phasic current signal analysis and … …American Journal of Applied Sciences, Vol. 11, Issue 6 · 11 Apr 2014 · 6,685 accessesView PDFCite
Research ArticleOpen accessIn the abstractACCELERATION AND PARTICLE FIELD INTERACTIONS OF COSMIC RAYS II: CALCULATIONSA. Tawfik, A. Saleh, M.T. Ghoneim et al.The Ultra High Energy Cosmic Rays (UHECRs) is still a one of the most controversial physical problems, especially that all potential acceleration mechanisms are not entirely able to explain the source of UHECR and their energy scale. Based on our generic acceleration model, that suggests different types of electromagnetic interactions between the cosmic charged particles and the different configurations of … …Physics International, Vol. 4, Issue 1 · 17 Jul 2013 · 7,196 accessesView PDFCite
