1. Localization, supersymmetric gauge theories and toric geometry
Abstract : Gauge theories is one of the most pervasive and important subject of modern theoretical physics, and there are still many things about them we do not understand. In particular dealing with strongly coupled theories where normal perturbative techniques do not apply is a fundamental open problem. READ MORE

2. Voltage Transients in the Field Winding of Salient Pole Wound Synchronous Machines : Implications from fast switching power electronics
Abstract : Wound Field Synchronous Generators provide more than 95% of the electricity need worldwide. Their primacy in electricity production is due to ease of voltage regulation, performed by simply adjusting the direct current intensity in their rotor winding. READ MORE

3. Run-Up Transient Analysis for Salient Pole Wound Field Synchronous Motors : Field winding and power electronics implications for a smoother and cooler asynchronous start
Abstract : Salient Pole Wound Field Synchronous Machines have better efficiency at full load than asynchronous machines of the same capability. Moreover, where asynchronous machines need inherently to draw a magnetizing current from the grid, Salient Pole Wound Field Synchronous Machines can work efficiently at unity power factor. READ MORE

4. Partial Discharges in Large Rotating Machines - Continuous On-line Monitoring and Localisation, Based on a New Developed Technique (InTech)
Abstract : Partial discharges (PD) that originate from dielectrically defective parts of the insulation system result in its degradation, which may ultimately lead to a failure of high voltage apparatus. This has resulted in development of numerous PD measuring techniques. One of the most widespread applications of PD measurement is in rotating machines. READ MORE
