PAPR Reduction of Optical OFDM Systems with Exponential Companding Transform and Zero Padding

Creator:

Chen, Deyan

Abstract:

Optical wireless communication (OWC) is an alternative to radio frequency (RF)communication with a signi cantly larger and unregulated spectrum. In OWC systems, optical orthogonal frequency division multiplexing (O-OFDM) with intensity modulation and direct detection (IM/DD) is commonly used. There are two common signal structures in most OWC systems based on...

Finite Element Analysis Modeling and Experimental Verification of Reflected Wave Phenomena in Variable Speed Machine Drive Cables

Creator:

Louie, Alex

Abstract:

Modern variable speed machine drive (VSMD) systems are used for a variety of purposes including generation, propulsion, pumps and compressors. They employ high switching frequency power electronics to drive the electric machine. The machine is subject to large voltage overshoot if long power cables, are used, called Reflected Wave Phenomena...

Determining The Impact of Photovoltaic Generation on Power Systems

Creator:

AL-Anazi, Falah

Abstract:

The National Conference of State Legislatures NCSL declares that 29 states have been active in adopting and increasing renewable portfolio standards. Present renewable portfolio standards require utilities to increase integration of renewable energy sources such as photovoltaic (PV). The increased penetration of PV systems is expected to destabilize the power...

Exploring security metrics for electric grid infrastructure leveraging attack graphs

Creator:

Patapanchala, Panini Sai

Abstract:

Electric grid is a critical cyber-physical infrastructure that serves as lifeline for modern society. With the increasing trend of cyber-attacks, electric grid security has become a significant concern. Electric grid operators are working hard to reduce the risk of these attacks towards the system. Having security metrics for monitoring the...

Computational Investigation on the Effects of Arc Location in Vacuum Arc Remelting

Creator:

Soler, Miguel

Abstract:

Vacuum arc remelting (VAR) is a secondary melting process for exotic alloys. The main purpose of this process is to increase the input ingot’s physical and chemical homogeneity. This is accomplished through the application of a high current that melts the material through the emergence of electrical arcs that induce...

Masters Thesis
Comparison of Direct Drive Hydraulic and Dual-Stator Spoke Array Vernier Permanent Magnet Machines For Ocean Wave Energy Conversion

Creator:

Azam, Ridwan

Abstract:

Recently, there has been peaked interest in developing high energy producing and optimized power take-off topologies for Wave Energy Converters (WEC). As large as the potential of the oceans may seem, harnessing that energy and effectively converting it to electricity in significant amounts is a challenge. Currently, there are no...
