A study of wave induced electron precipitation at low and middle latitudes.
(1991)
Wave induced electron precipitation (WIEP) can modify the ionosphere above
a sub-ionospherically propagating VLF signal in such a way as to perturb the
amplitude and phase of the signal: The "Trimpi Event".
In this ...
An investigation of gas lasers.
(1999)
Pulsed lasers have a wide range of applications in industry, medicine and for scientific
research. Many of these devices are expensive and have delicate optics. The nitrogen
laser is robust and inexpensive to build and ...
Theories and computation of second virial coefficients of electromagnetic phenomena.
(1997)
Many bulk properties of gases depend linearly on the gas density at lower densities, but as the density increases departures from linearity are observed. The density dependence of a bulk property Q may often be discussed ...
High repetition rate continuously tunable CO2 laser system investigation.
(1990)
The purpose of this thesis was to investigate certain factors
important for the operation of a high repetition rate continuously
tunable CO2 laser. The tuning range of specific importance for
this research program was ...
On the interaction of laser beams with air : with specific reference to refraction and scattering.
(1996)
The interaction of laser light with a parcel of air with a known density structure
can result in one of three reactions. The simplest of these reactions is reflection. Depending on the nature of the density profile, that ...
Planetary waves and the global ozone distribution.
(1994)
Planetary waves are known to play an important role in determining the annual variability in the severity of Antarctic ozone depletion. In this thesis, data obtained from the TOMS experiment on board the Nimbus-7 satellite ...
Refractive effects in phase objects and associated phenomena.
(1994)
The effect of the refraction of a laser beam propagating through three different
phase objects, i.e. a laser produced plasma and two different gas media,
is investigated in this thesis. It is shown that these effects ...
Velocity, vorticity and turbulence measurements in the surf zone.
(1999)
The coastal regions of the world play a significant role with regards to social and economic
development, and with the ever increasing human activities along the coast, it has become
necessary to understand and protect ...
Electrostatic wave phenomena in dusty plasma.
(1995)
This thesis is concerned with the some aspects of electrostatic wave phenomena dusty
plasmas. In particular Debye shielding, nonlinear potential structures such as diploar
vortices and solitons are investigated.
The ...
Low frequency electrostatic instabilities in a two-dust component plasma.
(1999)
The kinetic dispersion relation for a magnetized dusty plasma comprising of ions,
electrons and massive, charged dust particles is solved for low frequency electrostatic
instabilities in the dust plasma frequency ...
