#### The W Ursae Majoris systems : interpretation of light curves and line profiles

(University of Canterbury. Chemistry, 1971)

A method for the computer synthesis of theoretical light curves and like profiles for close binary stars in general has been developed and applied to the W Ursae Majoris stars. The geometry has been calculated using the ...

#### Stratospheric circulation : a narrowband filter spectrophotometer for total ozone determination

(University of Canterbury. Physics, 1975)

This thesis describes the use of ultraviolet narrowband interference filters in the spectrophotometric determination of local atmospheric total ozone burdens.
An investigation of a prototype interference filter ...

#### Atmospheric Ozone.

(University of Canterbury. Physics, 1971)

The development of a physically compact, light, robust and relatively cheap filter ozonometer for measuring the amount of ozone in the atmosphere is discussed.
Ozone data from the filter instrument and a Dobson ...

#### Radio-meteor investigations of atmospheric motion

(University of Canterbury. Physics, 1978)

A coherent pulse radar has been addressed to the problem of tracking drifting meteor trains to deduce neutral atmosphere velocities in the height range 80 to 110 km. The present work describes the principles of operation, ...

#### A quantum field theoretic formulation of atom-boson interactions

(University of Canterbury. Physics, 1978)

The results from the application of quantum field theoretic techniques to a number of problems in quantum optics are presented. We firstly evaluate the relative convenience of three possible mappings of spin operators to ...

#### Quantum mechanics and many-body problems effective operators in atomic energy level z-expansion calculations.

(University of Canterbury. Physics, 1972)

Rajnak and Wybourne's effective operators are generalized to degenerate ground configurations ℓN and ℓ'4ℓ' ℓN+2 as well as by removing the assumption of a Hartree-Fock basis. Explicit calculation of discrete radial integrals ...

#### Some properties of D-region partial reflections

(University of Canterbury. Physics, 1970)

In this work the conditions and requirements that lead to a randomly phased angular spectrum of plane waves are investigated. An experimental technique is developed from which the complex spatial correlation of the ...

#### Infinite sets of polynomial conserved densities for nonlinear evolution equations

(University of Canterbury. Physics, 1978)

The infinite sets of polynomial conserved densities which have been found for the Korteweg-de Vries equation, the modified Korteweg-de Vries equation, the Sine-Gordon equation, and the classical nonlinear shallow-water ...

#### Hydromagnetic waves in a buoyant medium

(University of Canterbury. Physics, 1976)

Lighthill has suggested that magnetic fields can transform gravity waves into Alfvén waves. The behaviour of gravity waves in an incompressible and infinitely conducting atmosphere is examined so as to check this suggestion. ...
