1. On Power-system Benefits, Main-circuit Design, and Control of StatComs with Energy Storage
Abstract : Static synchronous compensation (StatCom) is an application that utilizes a voltage source converter (VSC) to provide instantaneous reactive power support to the connected power system. Conventionally, StatComs are employed for reactive power support only. READ MORE

2. Voltage Source Converters with Energy Storage Capability
Abstract : This project deals with voltage source converters with energy storage capability. The main objective is to study the possible benefits of energy storage to a power system with a VSC as the interface between them. First of all, a converter control system is proposed for a two level VSC. READ MORE

3. Sex and stress steroid modulation of GABA mediated chloride ion flux in rat CNS
Abstract : Background: Sex and stress steroids are metabolized to 3a-hydroxy-pregnane-steroid metabolites such as allopregnanolone (Allo) and tetrahydrodeoxycorticosterone (THDOC). Allo and THDOC are neuroactive steroids that are metabolized in the brain and act in brain as potent positive GABAA receptor function modulators. READ MORE

4. Intrinsic tunneling spectroscopic investigations of Bi2Sr2CaCu2O8+x superconductors : The fluxon lattice, resonant phenomena,flux-flow and current doping
Abstract : In this thesis, the tunneling between individual atomic layers in structures of Bi2Sr2CaCu2O8+x based high-temperature superconductors are experimentally studied employing the intrinsic Josephson effect. A special attention is paid on the fabrication of small mesa structures using micro and nanofabrication techniques. READ MORE

5. Measurements of cosmic ray antiprotons with PAMELA and studies of propagation models
Abstract : Studying the acceleration and propagation mechanisms of Galactic cosmic rays can provide information regarding astrophysical sources, the properties of our Galaxy, and possible exotic sources such as dark matter. To understand cosmic ray acceleration and propagation mechanisms, accurate measurements of different cosmic ray elements over a wide energy range are needed. READ MORE
