An Appraisal Of Electricity Supply In Nigeria And The Privatisation Option, E. I. K. Sule, C. M. Anyanwu Aug 1994

An Appraisal Of Electricity Supply In Nigeria And The Privatisation Option, E. I. K. Sule, C. M. Anyanwu

CBN Occasional Papers

Incessant electric power cuts in most parts of the country has become a normal feature of electricity supply throughout Nigeria. The power outages cause much inconvenience and economic losses to all and sundry. This study has shown that the most critical factor behind the incessant power failure is the problem of inadequate funding of the industry at a time it was forced to accommodate rapid expansion. Other factors include lack of autonomy, inefficiency, poor organization as well as lack of skilled manpower. The paper has examined these problems on the basis of which suggestions are made on how the worrisome …

This information is central to the evaluation of hazards related to repetitive motion, excessive stress, and fatigue. Results can be used to select activities which should be targeted for future engineering design projects. Preliminary data from a commercial broccoli harvesting operation is included.


Upon Closer Inspection...U.S. Naval Aviation Mishaps 1977-1992, Scott A. Shappell, Douglas A. Wiegmann Apr 1994

Upon Closer Inspection...U.S. Naval Aviation Mishaps 1977-1992, Scott A. Shappell, Douglas A. Wiegmann

Publications

The U.S. Navy/Marine Corps Class A flight/flight-related mishap rate has declined markedly since 1953. However, analysis of all Class A, B, and C naval aviation mishaps between January 1977 and December 1992 reveals that mishaps attributable to human factors have declined at a slower rate than those attributable to mechanical/environmental factors. Upon closer inspection of the data, marked differences were evident between single-piloted and dual-piloted aircraft. Global trends were primarily a function of single-piloted aircraft, particularly when phase of flight and time of day that a mishap occurred are considered. Previously reported improvement in aviation safety may be biased by …


The Interpretation Of Laser Sensing Measurements For Blast Furnace Operations And Control, Peter C. Wall, R J Turner, Mark Hughes, Peter Huk, Ross J. Haywood, M J Mccarthy, Paul Zulli Jan 1994

The Interpretation Of Laser Sensing Measurements For Blast Furnace Operations And Control, Peter C. Wall, R J Turner, Mark Hughes, Peter Huk, Ross J. Haywood, M J Mccarthy, Paul Zulli

Faculty of Engineering and Information Sciences - Papers: Part A

Several laser-based sensors for use on blast furnaces have been developed and implemented, including a raceway sensor, burden level sensor (single point) and burden surface profiler. These sensors are based on the time-of-flight technique and give high levels of accuracy in all applications. The data obtained from the sensors during normal furnace operations are examined in light of the process models utilised by operators and for the interpretation of pulverised coal injection performance. Raceway sensory data obtained during a furnace blow-in are also discussed.


Low Temperature Synthesis Of Al-Aln Composites From A Nanostructure Made By Controlled Magneto-Ball Milling Of Al In Ammonia, Andrzej Calka, J I. Nikolov, G H. J Wantenaar Jan 1994

Low Temperature Synthesis Of Al-Aln Composites From A Nanostructure Made By Controlled Magneto-Ball Milling Of Al In Ammonia, Andrzej Calka, J I. Nikolov, G H. J Wantenaar

Faculty of Engineering and Information Sciences - Papers: Part A

The formation of an AlN compound in ball milled Al powder in ammonia was studied. In this work a magneto‐ball milling device with controlled ball movement was used. The end milling product was an Al based nanostructure. This product can be transformed into an AlN‐Al nanocomposite upon heating below the melting point of Al. It was found that the level of unreacted Al is dependent on milling time. The maximum amount of AlN was 88.28 wt %. The structure of as‐milled and annealed samples was investigated using x‐ray diffractometry and transmission electron microscopy. Differential thermal analysis was performed on as‐milled …


New Solutions For The Propagation Of Long Water Waves Over Variable Depth, Yinglong Zhang, Song-Ping Zhu Jan 1994

New Solutions For The Propagation Of Long Water Waves Over Variable Depth, Yinglong Zhang, Song-Ping Zhu

Faculty of Engineering and Information Sciences - Papers: Part A

Based on the linearized long-wave equation, two new analytical solutions are obtained respectively for the propagation of long surface gravity waves around a conical island and over a paraboloidal shoal. Having been intensively studied during the last two decades, these two problems have practical significance and are physically revealing for wave propagation over variable water depth. The newly derived analytical solutions are compared with several previously obtained numerical solutions and the accuracy of those numerical solutions is discussed. The analytical method has the potential to be used to find solutions for wave propagation over more natural bottom topographies.


A Three-Dimensional Numerical Model Of The Response Of The Australian North West Shelf To Tropical Cyclones, Song-Ping Zhu, Jorg Imberger Jan 1994

A Three-Dimensional Numerical Model Of The Response Of The Australian North West Shelf To Tropical Cyclones, Song-Ping Zhu, Jorg Imberger

Faculty of Engineering and Information Sciences - Papers: Part A

A three-dimensional barotropic and baroclinic model is developed to simulate currents and temperature changes induced by tropical cyclones traversing the continental shelf and slope region of the Australian North West Shelf. The model is based on a layered, explicit, finite difference formulation using the nonlinear primitive equations with an embedded entrainment scheme; a mixed-surface-layer interface is defined, which is allowed to shift from one interface to another, depending on the strength of a storm. The model has been tested by simulating the currents and temperature changes induced by tropical cyclones Orson and Ian. The modelled currents and temperatures agreed well …


The Strong Relevance Logics, Martin W. Bunder Jan 1994

The Strong Relevance Logics, Martin W. Bunder

Faculty of Engineering and Information Sciences - Papers: Part A

The tautology p - q - p is not a theorem of the various relevance logics (see Anderson and Belnap [1]) because q is not considered to be relevant in the derivation of final p. We can take this lack of relevance to mean simply that p-q-p could have been proved without q and its -, i.e., p-p. By the same criterion we could say that in ((p-p) -q) -q p-p is not relevant. In general we will say that any theorem A of an implicational logic is strongly relevant if there is no subpart B ! which can be …
