The effect of a pulse produced by an acoustic or electromagnetic
line source oriented parallel to the edge of a perfectly conducting
half plane is considered. The Green's functions for the modified
Helmholtz equation are found by solving for the Green's functions
for a cylinder of sectorial cross-section, then allowing...
The electromagnetic field produced by a line current oriented
parallel to the edges of two perfectly conducting parallel half
planes is considered. Maxwell's equations reduce to a single wave
equation involving only one component of the electric field. Moreover
the value of the field is zero on the two half...
A numerical solution to Hodgkin and Huxley's partial differential
system for the propagated action potential is presented. In
addition a three dimensional demonstration of the absolute refractory
period is given. Lastly, theoretical evidence supporting
Rushton's hypothesis is presented.
With the advent of underground testing, the study of the propagation of seismic signals has become of great importance. This thesis investigates the design of electrical analogs to represent the propagation of seismic waves. The analogs developed allow for the study of the effects of variations in the characteristic constants...
The character of the primary seismic wave in the
range of distances between 100 and 600 km is affected by
such factors as the nature of the source, exponential
attenuation, crustal structure, type of wave propagation,
recording site geology and instrument response. The
first arrivals from the GNOME and SHOAL...
Fourier transformed amplitudes of the compressional waves
recorded between 9° and 91° (about 1000 to 10,000 km) epicentral
distance from Gnome, Shoal, Haymaker,and Bilby underground
nuclear explosions have been compared with Fourier transformed
amplitudes of P waves measured at distances between 9.0 and
1 3. 0 km from the explosions....
A configuration-interaction determination of wave
functions has been made for the ²S and ²P states of lithium,
and for the ¹S and ³S states of the lithium ion.
Two 1s, one 2s, one 3s, and two 2p functions served as
starting functions for all four states. Results of the
total...
