Induction motors are widely used worldwide for domestic and industrial applications. Fault detection classification techniques based on signal analysis have increased in popularity due to the growing use of induction new technologies such as electric vehicles, automatic control, maintenance systems, inclusion renewable energy sources electrical among others. Hence, monitoring, fault detection, ...

This paper is on a simulation for offshore wind systems in deep water under cloud scope. The system is equipped with a permanent magnet synchronous generator and a full-power three-level converter, converting the electric energy at variable frequency in one at constant frequency. The control strategies for the three-level are based on proportional integral controllers. The electric energy is in...

We introduce a diffuse interface model for the phenomenon of electrowetting on dielectric and present an analysis of the arising system of equations. Moreover, we study discretization techniques for the problem. The model takes into account different material parameters on each phase and incorporates the most important physical processes, such as incompressibility, electrostatics and dynamic co...

A special class of molecules that are important to many subfields in molecular dynamics and chemical physics, namely free-radical molecules, now enjoy a significant degree of center-of-mass motion control in the laboratory frame. The example reported in this paper concerns the hydroxyl radical sOHd, which, after the internal degrees of freedom are cooled in a supersonic expansion, has been bunc...
