Diagnosis of Water Production using Artificial Neural Network Models
(2017-12-16)
A data-driven approach to solving the problem of excess water production was the focus of this study. In this research, several reservoir models were simulated for 26 years, and data obtained after simulation was used to ...
Substitutional and vacancy defects in two-dimensional AlSb: A first principle approach
(2019-07-22)
AlSb is a semiconductor material which exist in 3D as well as 2D regimes. AlSb have a high electron mobility which is useful for application in high speed electronic devices. AlSb has potential applications in radiation ...
Analysis of Horizontal Air-Silicone Oil Plug-To-Slug Transition Flow
(2019-06-23)
The analysis of the experimental data for the air-silicone oil plug-slug transition in a 67mm id and 6m long horizontal pipe was carried out in this work. The superficial gas and liquid velocity ranged from (0.05 – 4.73) ...
Comparative Analysis of Barite Production in Africa
(2019-06-12)
Successful oil and gas well drilling require hole stabilization. Barite comprised of barium sulphate is a common mineral chiefly used by oil and gas companies in their drilling operations. Barite is used in the drilling ...
Fiscal System Design and Economic Evaluation for Petroleum Resource Development in Ghana
(2019-06-12)
Petroleum fiscal regime defines the extent to which the host government and the prospective investor can apportion risks and share project rewards.
Ghana’s petroleum industry has become an attractive place for most investors ...
Observatory System for Monitoring Electric Power Demand and Delivery
(2017-11-22)
Nigeria is a fast-growing country in terms of urbanization. One of the major infrastructure challenge is power supply. However, this challenge is often not as a result of power generation but as a result of power distribution. ...
Topological Antiferromagnetic Magnons
(2019-07-12)
We have studied a model for a non-collinear but coplanar antiferromagnetic spin texture on a two dimensional kagome lattice structure in the presence of Dzyaloshinskii-Moriya Interaction (DMI). We observed some interesting ...
Pulsed Lasers in Lidar Application: Models for Optimizing Wind Turbine Performance
(2019-06-22)
Since the appearance of the first wind turbines at the end of the nineteenth century, wind energy has been considered to be a renewable energy source for not just developed countries but also developing countries as well. ...
Theoretical Study of Current-Induced Dynamics of an Antiferromagnetic Skyrmionium
(2019-06-22)
In this thesis, we present a theoretical study on the current-induced nucleation and propagation of antiferromagnetic skyrmionium. A skyrmionium, also known as 2π-skyrmion, is a vortex-like magnetic structure characterized ...
Structural, Electronic and Optical Properties of Cu 2 Sns 3 Solar Absorber: A First-Principle Density Functional Theory Investigation
(2019-06-23)
The development of inexpensive, non-toxic, high efficiency and earth-abundant solar absorbers is critical for terawatt scale implementation of photovoltaics. Cu 2 SnS 3 is a promising earth abundant absorber material that ...
