A Strong Convergence for the sum of three Monotone Operators in a Real Banach Space
(AUST, 2021-07-09)Let E be a real 2-uniformly convex Banach space with topological dual E∗. We established strong convergence for the class of variational inclusion for the sum of three monotone operators. More over, we give a variant of ...

Modified Forward-Backward Splitting Method Without Cocoercivity for the sum of two Monotone Operators in Banach Spaces
(AUST, 2021-07-10)In this thesis, we present an algorithm for solving a variation inclusion problem of sum of two monotone operators in real Banach spaces which uses variable step sizes that are updated over each iteration by some cheap ...

Analytical Solution to Pressure Transient Analysis in Non-Newtonian/Newtonian Fluids Composite Reservoirs
(AUST, 2021-04-03)During polymer flooding in the reservoir using shear-thinning non-Newtonian fluids, an interface exists between the in-situ Newtonian crude in the reservoir and the injected polymer solution. This work examines application ...

Prediction of Liquid Holdup for a Multi-Plane System Using Artificial Neural Network
(AUST, 2020-12-03)Liquid holdup was predicted for slug flow using the neural network toolbox available in MATLAB. Experimental data contained Liquid holdup measured at an interval of 5 seconds over a period of 12,000 time points for both ...

Injectivity as a Critical Factor in The Performance of Water Flooding Operation
(AUST, 2021-04-02)Petroleum exploration, development and operation usually involves large capital investments that requires maximum reserves be recovered, so as to compensate for initial investment efforts. To achieve such a goal, where the ...

Feasibility Analysis of Ethane and Flue Gas Injection for Enhanced Oil Recovery With a Niger Delta Case Study
(AUST, 2021-05-13)Enhanced oil recovery (EOR) using ethane gas or flue gas has proven to be successful in some regions of the world, but these methods have not been implemented in the Niger Delta. This work investigates the technical and ...

The Effect Of Osteogenesis on the Mechanical Properties of a 3-D Polylactic Acid Scoffold
(AUST, 2021-06-10)Poly-Lactic Acid is used widely in biomedical applications due to its good biocompatibility (i.e. biological and chemical inertness) and biodegradability. The area of tissue Engineering has been explored for the regeneration ...

Ensemble Learning for URL Phishing Detection
(AUST, 2020-07-13)Phishing is a social engineering attack that has been perpetuated for long and is still a prominent attack with an attending high number of victims. The adverse effect of this allows phishers easy access to sensitive ...

Bidirectional Search in a String Using Wavelet Matrix and Burrows Wheeler Transform
(AUST, 2020-08-02)Wavelet tree is a data structure which permits the representation of sequences of symbols over an alphabet of size σ. It recursively partitions a string into two halves until homogeneous data is obtained. An increase in ...

Modeling of the Origin and Interactions of Multisoliton Solutions of the (2+4)KdV Equation
(AUST, 2019-06-05)Most of the relevant research work has addressed the properties of internal solitons in a greatly simplified environment, usually in the framework of different versions of the two layer fluid. The simplest equation of this ...

Structural and electronic properties of a two-dimensional hybrid system of graphene and hexagonal boron nitride: A first-principles study
(AUST, 2019-06-02)Despite the excellent properties of graphene, graphene based electronic devices are yet to be realized, one of the reason for such is the absence of band gap in graphene. Due to its large band gap, hexagonal boron nitride ...
