Investigating the Behaviour of Air-Silicone Oil Flows in Vertical and Horizontal Pipes for Effective Gas-Liquid Transport
(2016-06-12)
The concurrent flow of gas/liquid in pipes poses a great challenge due to the difficulty associated with the flow of fluid. The flow is characterized by the existence of flow regimes which can be identified by the geometrical ...
Towards a New Exchange-Correlation Density Functional for more Accurate Band Gap Predictions
(2016-06-17)
Density-Functional Theory (DFT) offers a simplification to electronic structure problems by using the electron density instead of the wave-function. Unlike the wave-function which is a function of 3N variables (excluding ...
A Naive Finite difference Approximations for Singularly Perturbed Parabolic Reaction-Diffusion problems
(2016-06-07)
In this thesis, we treated a Standard Finite Difference Scheme for a singularly perturbed parabolic reaction-diffusion equation. We proved that the Standard Finite Difference Scheme is not a robust technique for solving ...
Optical Properties of Metal Clusters from First Principles Calculations
(2016-06-17)
Ground State structures of neutral Copper clusters Cu N =3−6 were generated and optimised within the framework of the Density Functional Theory (DFT) using Generalised Gradient Approximation (GGA) and ultrasoft pseudopotential. ...
A Strong Convergence Theorem for Zeros of Bounded Maximal Monotone Mappings in Banach Spaces with Applications
(2016-06-07)
Let E be a uniformly convex and uniformly smooth real Banach space and E ∗ be its dual.
Let A : E → 2 E be a bounded maximal monotone map. Assume that A −1 (0) 6 = ∅. A new iterative sequence is constructed which converges ...
On J-fixed points of J-pseudocontractions with applications
(2016-06-07)
Let E be a real normed space with dual space E ∗ and let A : E → 2 E be any map. Let J : E → 2 E be the normalized duality map on E. A new class of mappings, J-pseudocontractive maps, is introduced and the notion of J-fixed ...
Ultrafast X-rays Imaging For Medical Physics
(2016-06-17)
In this thesis we explored the production of highly coherent and energetic extreme ultra violet(XUV) radiation through the process of high harmonic generation(HHG). HHG is a process by which a ultrashort laser pulse interact ...
Material Balance Application for Brownfield Development
(2016-06-12)
The need to re-develop one of the Brown fields located in the Niger Delta area of Nigeria was necessitated by the fact that there are still three undeveloped reservoirs in the field. A total of six stacked reservoirs, A100 ...
Artificial Neural Network for Diagnosis & Mitigation of Water Production
(2016-06-12)
From the inception of the oil and gas industry, water production has always been an aching problem for various operators. Throughout the productive life of a field, oil production is often accompanied with some amount of ...
An Algorithm for Solutions of Hammerstein Integral Equations with Monotone Operators
(2016-06-07)
Let X be a uniformly convex and uniformly smooth real Banach space with dual space X ∗ . Let F : X → X ∗ and K : X ∗ → X be bounded monotone mappings such that the Hammerstein equation u + KF u = 0 has a solution in X. An ...
