Excess noise in n-type hydrogenated amorphous silicon
(1997-01-01)
Recently, there has been much uncertainty and controversy concerning various aspects of the behaviour of the excess noise in n-type a-Si:H known as 1/f or flicker noise. Conductance fluctuations have been measured in ...
A fault tolerance technique for feedforward neural networks
(1997-01-01)
The use of neural networks in critical applications necessitates that they continue to perform their tasks correctly despite the possible occurrence of faults. The objectives of this dissertation were to develop a technique ...
Theoretical and experimental investigations on radial electromagnetic forces in relation to vibration problems of induction machines
(1997-06-01)
Accurate assessment of the electromagnetic excitation forces and the vibration behaviour of stators is essential to arrive at a suitable design for quiet operation of an electrical machine. These electromagnetic forces are ...
Economic impact of non-utility generation on electric power systems
(1997-01-01)
Non-Utility Generation is a major force in the way electrical energy is now being produced and marketed, and electric utilities are reacting to the growth of this new industry. When a utility buys electric energy from a ...
Cost/benefit assessment of power system reliability
(1997-01-01)
Value based planning in power systems is becoming increasingly important due to required system investment costs and the necessity to quantify and justify system reliability levels. Utilities faced with increasingly ...
Passive localization of an underwater acoustic source using directional sensors
(1995-01-01)
This thesis studies the passive localization (bearing estimation and range and depth estimation) of a single stationary underwater acoustic source in a two-path (direct and surface-reflected path) environment. The main ...
Shape and size characterization of crystals using image analysis and neural networks
(1997)
The characteristic properties of potash (KC1) crystals depend not only upon their
chemical composition but on their morphological attributes as well. Hence, to determine the
quality or grade of the crystalline product, ...
Charge transport in stabilized A-Se films used in X-ray image detector applications
(1999-01-01)
The suitability of stabilized amorphous selenium (a-Se:0.2-0.5%As, 10-20 ppm Cl) as an x-ray imaging receptor is largely determined by its charge generation, transport, and trapping properties. The product of the charge ...
Reliability assessment of non-utility generation and demand-side management In composite power systems
(1998-09-01)
The last two decades have brought about significant changes in the resource planning environment of electric power utilities throughout the world. The conventional generation technologies that have been the backbone ...
Determining the locations of faults in distribution systems
(1998-01-01)
The conventional approach for estimating the locations of transmission line faults has been to measure the apparent impedance from a line terminal to the fault and to convert the reactive component of the impedance to line ...
