Supply chain management (SCM) has been considered as a competitive strategy for integrating suppliers and customers with the objective of improving responsiveness and flexibility of manufacturing organizations. A key issue in SCM is how to entice all parties to cooperate and coo…
In this thesis, a novel one-dimensional fringe-adjusted joint transform (1D-FJTC) correlation technique and an adaptive band selection technique is proposed for detecting small objects involving only a few pixels in hyperspectral imagery. In the 1D-FJTC, one dimensional (1D) spe…
Nigeria is on the threshold of comprehensively reviewing its oil and gas laws with a view to, among others, addressing the conflicts associated with the management of the resources, especially as it affects the people of the oil producing region of the country who have been vigo…
Extraordinary magnetoresistance (EMR) in semiconductor-metal hybrids has been studied exclusively for sensor applications. However, some properties of EMR-based devices are potentially advantageous for power applications. A PSPICE finite-element model has been developed to aid i…
As tsunami waves travel towards the shoreline, they may break offshore and runup the shore as a hydraulic bore. Recorded videos from the December 26, 2004 Indian Ocean Tsunami show that tsunami waves transformed into a hydraulic bore that propagated onshore with considerably hig…
In this thesis, we present a probabilistic generative approach for learning hierarchical struc- tures of spatially local features, effective for visual recognition. Recently, a greedy layerwise learning mechanism has been proposed for training fully-connected neural networks. Th…
This report argues that the nature and importance of organisational structures of foreign aided construction and infrastructure projects, and their underpinning de sign principles are not well understood and yet they play a key role in organisational and project performance. Thi…
Trailing edge cooling cavities in modern gas turbine airfoils play an important role in maintaining the trailing edge temperature at levels consistent with airfoil design life. These cavities often have a trapezoidal cross-sectional shape in order to be compatible with the exter…
Glass fiber reinforced vinylester (GFRE) and epoxy (GFRE) pipes have been used for more than three decades to mitigate corrosion problems in oil fields, chemical and industrial plants. In these services, both GFRV and GFRE pipes are exposed to various environmental conditions. L…
In this work we describe a Parallel External Memory System (PEMS) which provides a framework and interface to convert Bulk Synchronous Parallel (BSP) programs into external memory programs based on the theoretical results of [12, 30]. The results in [12, 30] show how to adapt pa…
The thesis is based on using mathematical approaches to gain insights into the transmission dynamics of malaria, a disease of major public health significance. Since mosquito vector is critically important to malaria dynamics, a model for the population dynamics of the malaria v…
In recent years, the higher price of fossil fuels and green house effects has been the motivating factors for the automotive industry to introduce more efficient vehicles. Today evolution in automobiles is mostly to reduce fuel consumption and emissions. Variable cylinder manage…
The domain of electronics undergoes continuous development to meet consumer demands while keeping up with "Moore's law". One of the approaches to meet these requirements is the use of multiple die in a single packaging module with a thinner package thickness. This research is a …
One special type of memory use for high speed address lookup in router or cache address lookup in a processor is Content Addressable Memory (CAM). CAM can also be used in pattern recognition applications where a unique pattern needs to be determined if a match is found. CAM has …
Metal forming industries are constantly looking for ways to increase their productivity and competitiveness by advancing innovative, economical, energy-efficient, and environmentally friendly metal forming techniques. Superplastic Forming (SPF) has a great potential to he one of…
Laser-scanning microscopy (LSM) has become a standard technique for biomedical imaging at the cellular and sub-cellular level. LSM is not only widely used as a powerful biological imaging tool but also as a research platform for investigating new imaging modalities. However, eme…
The crystal growth of ZnO-TeO2 system was experimented by Czochralski and Bridgman techniques. The series of many runs and experimentations helped optimize the growth process, which was faced by a lot of difficulties. These difficulties include, but are not limited to, the evapo…
