Investigation of the accuracy of Grover's method when solving for the mutual inductance of two single-layer coaxial coils
(University of Missouri--Columbia, 2005)
In 1933 Grover introduced a convenient method of calculating the mutual inductance between two single-layer coaxial coils that is still widely accepted as the standard today. He produced tables of numeric values from Clem's ...
Theoretical investigation of a laser triggered spark gap
(University of Missouri--Columbia, 2005)
A model of a spark gap used as a shorting switch in a Blumlein pulse power system has been developed. The model is separated into a pre-breakdown kinetic model and a post-breakdown fluid model. The kinetic model is used ...
A fast, 3 MV Marx generator for megavolt oil switch testing and integrated Abramyan network design
(University of Missouri--Columbia, 2005)
The University of Missouri-Columbia has a new test facility online to study oil breakdown of enhanced and uniform gaps. The 3 megavolt Marx generator is operational with switch configurations tested including large electrode ...
Performance evaluation of a low cost processor with wireless connectivity
(University of Missouri--Columbia, 2005)
This study shows the development and analysis of the connectivity of a wireless system using a low cost processor. First, we designed a system with two sensor processors and a server PC. Second, we developed two protocols; ...
Simulation and experimental study of the multichanneling rimfire gas switch
