HARMONIC-SUPPRESSED MINIATURIZED-ELEMENT FREQUENCY SELECTIVE SURFACES WITH HIGHER-ORDER BANDPASS RESPONSES
(2013-12-22)In this reprot, we introduce a new technique for designing miniaturized-element frequency selective surfaces (MEFSSs) with bandpass responses and no spurious transmission windows over extremely large bandwidths. The ... -
High Power Microwave Breakdown Study
(2011-08-26)In this research a rapidly forming (<50 ns) self-initiating distributed plasma discharge was observed using an X-band (WR-90) microwaves. We also observed slower forming (300-400 nS) plasma breakdown with 1 kHz repeated ... -
High Power Microwave Breakdown Study
(2011-08-15)Microwave Breakdown Experiments in Ne, Ar and Penning Discharges (Abstract) In this research a rapidly forming (<50 ns) self-initiating distributed plasma discharge was observed using an X-band (WR-90) microwaves. We ... -
Implementation of a DC Microgrid
(2017-05-31)The first permanent electric grid powered only the homes and buildings in its immediate vicinity–much like microgrids, which are presently the focus of intense research and development. An area holding great promise for ... -
Implementation of Complement Mode Execution
(2011-08-26)As technology goes deeper into the submicron range device aging effects become increasingly powerful. The Colt duty cycle equalizer gives a microarchitectural solution to this problem with execution of complemented data ... -
Improving Video Transportation over Dynamic Wireless Networks
(2017-05-22)This thesis explores video transfer over dynamic wireless communication links in an attempt to understand current limitations and propose new methods to push performance beyond the existing envelope. To this end, I spent ... -
Initial Applications of Synchrophasors Using Area Angles
(2012-05-20)Synchrophasors allow fast, synchronized measurements of the power grid and have the potential to serve power system applications more e ectively. Synchrophasor data may allow analyzing subareas of the system without need ... -
Integrated Inductors and Capacitors with Co-Located Electric and Magnetic Fields
(2017-01-05)Passive components such as inductors and capacitors are fundamental components needed in all power electronics converters, and in many designs, they comprise a significant portion of the total weight and volume of the ... -
Intracranial Pressure Sensor
(2014-05-18)Develop and fabricate a permanently implanted passive pressure sensor to measure intracranial pressure (ICP). At anytime, the hydrocephalic patient, care taker, or physician can hold an external display device over the ... -
An Investigation for Strengthening Existing Reinforced Concrete Beams in Shear Using a MF-FRP Retrofit System
(2011-05-15)The purpose of this research was to determine if a Mechanically-Fastened Fiber Reinforced Polymer (MF-FRP) Retrofit System is viable for increasing shear strength in existing reinforced concrete beams. Due to the more ... -
Ion energy distributions for collisional ion sheaths at an rf-biased plasma electrode
(2010-05-15)In plasma etching for materials processing, ions are often accelerated towards the substrate via a sheath electric field generated by a bias voltage applied to the substrate electrode. By applying at tailored bias waveform ... -
JERK LIMITED TRACKING MODE FOR SOFIA CAVITY DOOR DRIVE SYSTEM
(2011-08-26)A 5th order polynomial spline function is applied to the position command generation of the SOFIA cavity door drive system in order to limit jerk. By limiting the door jerk, a smooth acceleration profile is achieved and ... -
Load Dynamic Performance Sensitivity Analysis with respect to End-Use Motor Characteristics and Distribution Feeder Networks
(2010-05-15)Motor dynamics sensitivity analysis with respect to end-use motor characteristics (inertia, load torque profile, electrical parameters) is presented in this thesis. Mechanical data of motors play a very important role ... -
Localization of Forced Oscillation - A Model Based Approach
(2023)The electricity grid is one of the most impressive engineering feats of the modern era. It enables power transmission from a variety of generation facilities to end users over long distances. It provides electricity to ... -
Locational Effects of Variability of Power Generation and Loads on Total Cost of Power Systems
(2015)In this thesis locational prices associated with power injection variability are introduced. Using a probabilistic DC optimal power flow (DC-OPF), the sensitivity of uncertainty in injected power on system cost is calculated. ... -
Machine Learning Approach to Event Detection for Load Monitoring
(2019)Today’s Electricity market is highly interconnected. The actions of customers, transmission and distribution systems, generation systems, markets, and service providers are correlated. The dynamic stability of the grid ... -
Maximizing Throughput of Power-Constrained Multi-Core Processors Manufactured with Unreliable CNFETs
(2011-05-15)Silicon is used in making transistors conventionally but scaling of silicon if getting difficult with time.Scaling of silicon has become difficult lately.Without scaling we won?t have more transistors on chip every year ... -
MEASURING D? AND X ? IN THE HSX EDGE
(2013-05-19)Stellarator design has substantially improved over the past decade, but stellarator edge physics, especially in terms of heat and particle exhaust, is still not well-understood. Codes such as EMC3-EIRENE [8] are being ... -
Metamorphic Testing and its Application on Hardware Fault-Tolerance
