Signal processing techniques for on-line partial discharge monitoring of high voltage electrical machines. (1994)
Thesis
JAMIESON, J.W. 1994. Signal processing techniques for on-line partial discharge monitoring of high voltage electrical machines. Robert Gordon University, PhD thesis. Hosted on OpenAIR [online]. Available from: https://doi.org/10.48526/rgu-wt-1584896

Large alternating current electrical machines are found everywhere in modern industry. Traditionally, electrical plants have been highly reliable, primarily because the complexity of their electrical design means that they are generously over-rated....

The management of aircraft passenger survival in fire. (1993)
Thesis
TRIMBLE, E.J. 1993. The management of aircraft passenger survival in fire. Robert Gordon University, PhD thesis.

This study examines the main problems associated with passenger survival and evacuation in survivable aircraft fire situations under current regulatory safety requirements and assesses current and alternative strategies to combat cabin fire, and assi...

The monitoring of induction motor starting transients with a view to early fault detection. (1992)
Thesis
ELDER, S. 1992. The monitoring of induction motor starting transients with a view to early fault detection. Robert Gordon University, PhD thesis.

The aim of this work is to investigate the possibility of detecting faults in a 3 phase Induction motor by monitoring and analysing the transient line current waveform during the starting period. This is a particularly onerous time for the machine an... Read More about The monitoring of induction motor starting transients with a view to early fault detection..

Partial discharge measurements in high voltage motors. (1987)
Thesis
BUCHAN, J.G. 1987. Partial discharge measurements in high voltage motors. Council for National Academic Awards, PhD thesis.

The work presented in this thesis is concerned with the development of an on-line technique for detecting and locating partial discharges in the stator winding of a high voltage electrical machine. This technique forms part of an on-line health monit... Read More about Partial discharge measurements in high voltage motors..

Flow induced acoustic resonances in heat exchangers. (1986)
Thesis
RAE, G.J. 1986. Flow induced acoustic resonances in heat exchangers. Council for National Academic Awads, PhD thesis.

This thesis describes an investigation into the acoustic phenomenon in in-line tubular heat exchangers subjected to cross flow. The flow through such a heat exchanger can result in the production of very high noise levels, which occur as a result of... Read More about Flow induced acoustic resonances in heat exchangers..

Computer aids for the design of large scale integrated circuits. (1983)
Thesis
SWAN, G. B. 1983. Computer aids for the design of large scale integrated circuits. Council for National Academic Awards, PhD thesis.

The work described in this thesis is concerned with the development of CADIC (Computer Aided Design of Integrated Circuits), a suite of computer programs which allows the user to design integrated circuit layouts at the geometric level. Initially, a... Read More about Computer aids for the design of large scale integrated circuits..

Alkene hydrogenation on reduced nickel A-zeolite catalysts. (1983)
Thesis
WILLIAMS, S.G. 1983. Alkene hydrogenation on reduced nickel A-zeolite catalysts. Robert Gordon's Institute of Technology, PhD thesis. Hosted on OpenAIR [online]. Available from: https://doi.org/10.48526/rgu-wt-1993288

The individual and competitive hydrogenation reactions of ethene, propene and isobutene over various nickel metal-loaded 4A zeolites have been investigated. The reaction kinetics were found to be similar to those found by other workers for alkene hyd... Read More about Alkene hydrogenation on reduced nickel A-zeolite catalysts..

Selected modifications of the auditory feedback system and their effects on speech fluency. (1982)
Thesis
LOW, J.M. 1982. Selected modifications of the auditory feedback system and their effects on speech fluency. University of Aberdeen; Robert Gordon's Institute of Technology, PhD thesis. Hosted on OpenAIR [online]. Available from: https://doi.org/10.48526/rgu-wt-1993308

It has been accepted for some time that we continually monitor our own speech by listening to ourselves; indeed, the absence of this monitoring system is detrimental to our speech performance. In the congenitally deaf, acquiring the skill of speech i... Read More about Selected modifications of the auditory feedback system and their effects on speech fluency..

Adaptive control of communication networks using learning automata. (1982)
Thesis
CHRYSTALL, M.S. 1982. Adaptive control of communication networks using learning automata. Council for National Academic Rewards (CNAA), PhD thesis.

This research investigates communications network routing procedures, based on distributed learning automata concepts for circuit and packet switched networks. For this application, the learning automaton is shown to be an ideal adaptive control mech... Read More about Adaptive control of communication networks using learning automata..

An investigation of eddy diffusivities of momentum and heat in circular pipes. (1981)
Thesis
CHEONG-KI, C. 1981. An investigation of eddy diffusivities of momentum and heat in circular pipes. Council for National Academic Awards, PhD thesis.

The theoretical analysis of the present work was based on a thermodynamic approach, using the method of inference. An analysis was made to find the macroscopic turbulence transport properties from the description of microscopic behaviour of entities...

Properties of a high-current discharge in alkali-metal-seeded rare gases. (1969)
Thesis
ELLINGTON, H.I. 1969. Properties of a high-current discharge in alkali-metal-seeded rare gases. Robert Gordon's Institute of Technology, PhD thesis.

This thesis is an account of a detailed investigation of the properties of a recently-discovered gas discharge - a discharge that operates at a few volts or tens of volts, and which carries a current of the order of amps through a mixture consisting...
