The study of single phase diode rectifiers with high power factor and low total harmonic distortion
(University of Missouri--Columbia, 2008)
The mains current in an ac/dc converter contains periodic current pulses due to the action of rectifier and output filter capacitor. The high current peaks cause harmonic distortion of the supply current and low power ...
Modeling the behavior of a homopolar motor
(University of Missouri--Columbia, 2008)
The design, construction, and operating characteristics of a homopolar motor are described in this thesis using both physical experimentation and simulation software. This type of motor converts electrical energy into ...
Anti-fog coatings using the super-hydrophobic approach
(University of Missouri--Columbia, 2008)
Surfaces with water contact angles in excess of 150[degrees] have been attracting a great deal of attention. The work done here was in the design and development of an anti-fog coating. The hydrophilic as well as the ...
Low loss film bulk acoustic resonator in liquid environments
(University of Missouri--Columbia, 2008)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] A film bulk acoustic resonator (FBAR) is an acoustic resonator mass sensor using the resonance of longitudinal or shears acoustic waves. There is a ...
Compact power conditioning and RF systems for a high power RF source
(University of Missouri--Columbia, 2008)
As part of the University Consortium for High Power Microwave (HPM) Integration, compact power conditioning and RF systems were investigated with a maximum diameter of 15.24 cm. A simulator of a flux compression generator ...
Magnetoresistance in semiconductor-metal hybrids for power applications
(University of Missouri--Columbia, 2008)
Extraordinary magnetoresistance (EMR) in semiconductor-metal hybrids has been studied exclusively for sensor applications. However, some properties of EMR-based devices are potentially advantageous for power applications. ...
High-speed, high-accuracy method for mutual inductance calculations
(University of Missouri--Columbia, 2008)
Three methods for calculating the mutual inductance of coils are examined and compared: a finite-element field code analysis method, theoretical analysis method, and F. W. Grover's tabular method. These methods are applied ...
A TEM cell design to study electromagnetic radiation exposure from cellular phones
(University of Missouri--Columbia, 2008)
A transverse electromagnetic (TEM) cell was designed and fitted with a double ended monopole antenna as a signal leader in order to couple electromagnetic radiation from GSM 900 and 1800 commercial cellular phones into a ...
Shallow trench isolation process in microfabrication for flash (NAND) memory
(University of Missouri--Columbia, 2008)
Technology is steadily advancing where semiconductors and microelectronics have become such a huge source of revenue and area of technological interest, resulting in reduced device geometries and more complicated microelectronic ...
Optically enhanced nano-forest cathodes
(University of Missouri--Columbia, 2008)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Optically enhanced nano-forest cathodes are electron sources developed for high power devices. The principle of cathode operation is based on coherent ...
The ferroelectric plasma thruster
(University of Missouri--Columbia, 2008)
Micropropulsion is an enabling technology for microspacecraft. As requirements for microspacecraft missions become more demanding, so do the requirements for micropropulsion. Therefore, existing technologies require ...
Effects of nano-second pulsed electric fields (nsPEF) on human prostate cancer cell line - LNCaP
(University of Missouri--Columbia, 2008)
The effects of Pulsed Electric Fields have been a period of study since past few decades, which was mainly on the electroporation, bacterial decontamination and biofouling. But the development of technology to produce ...
Design and construction of helmholtz coil for biomagnetic studies on soybean
(University of Missouri--Columbia, 2008)
A Helmholtz coil with a large usable area of uniform field was designed, constructed and characterized, specifically for bioelectric studies. The design and analysis of the coil were carried out through experiments and the ...
Laser target triggering of gas switches
(University of Missouri--Columbia, 2008)
Laser target triggering has been investigated at the University of Missouri as a method to reduce the laser energy required to trigger a laser triggered gas switch. Laser targets were solid materials embedded into the ...
MSM photodiode as the switching element in a photoswitch-based class E microwave power amplifier
(University of Missouri--Columbia, 2008)
A photoswitch is designed for use as the switching element in a 2 GHz class E amplifier. The application of this amplifier is as the final-stage amplifier in the transmit-receive module of a phased-array radar system. The ...
Runtime and jitter of a laser triggered gas switch
(University of Missouri--Columbia, 2008)
The University of Missouri has studied parameters affecting the runtime and jitter of a laser triggered gas switch. Experiments tested a variety of switch parameters including percentage of self-break and charge voltage. ...
