Fundamentals of Laser Dynamics
(2013-05-13)
The thesis presents the modeling and simulation of three types of lasers namely; Semicondoctor laser, Solid state laser and CO 2 laser. The rate equations were derived and simulated to examine the dynamic behaviour of the ...
Simulation-Based Model Thermal Ablation of Prostate Cancer Using High Intensity Focused Ultrasound
(2014-12-20)
The use of High Intensity Focused Ultrasound (HIFU) in the medical treatment of cancer has attracted scientists and engineers with interest in achieving the most financially affordable but yet curative methods of curing ...
Maximal Monotone Operators on Hilbert Spaces and Applications
(2016-05)
Let H be a real Hilbert space and A : D(A) ⊂ H → H be an unbounded, linear, self-adjoint, and maximal monotone operator. The aim of this thesis is to solve u 0 (t) + Au(t) = 0, when A is linear but not bounded. The classical ...
Why Classical Finite difference Approximations fail for a singularly perturbed System of Convection-Diffusion Equations
(2016-06-07)
We consider classical Finite Difference Scheme for a system of singularly perturbed convection-diffusion equations coupled in their reactive terms, we prove that the classical SFD scheme is not a robust technique for solving ...
An Integrated Approach to Selecting and Optimizing Demulsifier Chemical Injection Points using Shearing Energy Analysis: A Justification for Downhole Injection in High Pressured Well
(Offshore Technology Conference, 2011-05-05)
Chemical demulsifiers are routinely injected into the petroleum production system at several points to effectively resolve water-in-oil emulsion issues. Point of injection varies from downhole through wellhead and manifolds ...
A Study of the Pre-Treatment Temperature of Lignocellulosic Butanols an Alternative Fuel (BIOFUEL) Produced from Bamboo using Clostridium Acetobutylicum
(2013-05-12)
Conversion of lignocellulosic biomass from bamboo (Bambusa vulgaris) to butanol is an important alternative energy source. In this work, bamboo was used as biomass feedstock for the production of butanol by the fermentation ...
The Role of Sulfur Oxidizing Bacteria on Corrosion of X65 Low Carbon Steels and its Mitigation Using Sodium Tungstate and Nickel Biocides
(2013-05-12)
Metals in service often give a superficial impression of permanence, but all except gold are chemically unstable in air and air-saturated water at ambient temperatures and most are also unstable in air-free water. Corrosion ...
Implantable Biomems Devices for Localized Breast Cancer Drug Delivery
(2011-12-15)
Implantable Bio-Micro-Electro-Mechanical Systems (BioMEMS) represent a new class of devices that can provide localized cancer drug delivery by the combined effect of chemotherapy and hyperthermia which gives it an advantage ...
Numerical Modeling of Wellbore Instability (SHEAR Failure) using Fracture Mechanics Approach
(2013-05-12)
Wellbore instabilities are responsible for 10-20% of the total drilling cost. It has been estimated that wellbore instability causes an annual economic loss of US$ 500 - 1000 million in the oil industry across the world. ...
Controlled Release of Fungicidal Antimicrobials on Packaged Foods
(2014-12-15)
This paper presents the effect of polymer concentration on the release of fungicidal antimicrobial (AM) agent to prolonging the shelf life of packaged food. This project aimed to produce and test AM films with varying ...
