Parametric Analysis of a ConvergentDivergent Nozzle for 2N Cold Gas Propulsion of a Nanosatellite
(AUST, 20210909)In recent times, the concepts of microsatellite development have been a versatile subject ranging from their ability to reduce overall cost of satellites to their improved efficiency and adaptability. This has brought new ...

Design and Analysis of CBand Microstrip Patch Antenna for Satellite Communication
(AUST, 20210901)Low gain and narrow bandwidth associated with microstrip patch antennas for satellite application is studied in this submission. Evaluation of the best feed technique with insertand edge using HFSS software was done with ...

Optimization of Battery Management System on Nano Satellite
(AUST, 20210910)Battery Management Systems (BMS) are tasked so as to provide an optimum and efficient control over the battery in any satellite EPS. Along with efficiency, these systems also require intelligent safety measures to avoid ...

Estimation of Shortwave Broadband Irradiance at the Bottom of the Atmosphere Over Ilorin in Central Nigeria Using Radiative Transfer Model
(AUST, 20210901)Shortwave Broadband Irradiance (SBI) makes up about 96% of the Total Solar Irradiance (TSI) received on earth, and it is known to be the major driver of climate change. The SBI also contains ultraviolet radiation, which ...

Evaluation of Machine Learning Tools for Predicting Sand Production
(AUST, 20210310)Data analytics has only recently picked the interest of the oil and gas industry as it has made data visualization much simpler, faster, and costeffective. This is driven by the promising innovative techniques in developing ...

Assessing the Implications of Low Carbon Emissions on Future Oil Production in Nigeria
(AUST, 20210613)Nigeria economy solidly depends on fossil fuels, which serve as the major source of energy and revenue. Fossil fuels, especially petroleum, are readily available to meet the increasing energy demand of a growing population. ...

Framework for Optimal Economic Exploration and Exploitation of Petroleum Resources in Cameroon
(AUST, 20210603)Economic exploration and exploitation of petroleum resources is regarded as being optimal when the surrounding fiscal regime is mutually beneficial to both the government and the investors as well as other stakeholders, ...


SingleStep Algorithm for Variational Inequality Problems in Banach Spaces
(AUST, 20210710)In this work, we propose a onestep algorithm for solving variational inequality problems in a 2uniformly con vex Banach space. Weak convergence of the scheme to a solution of variational inequality is established under ...

Bochner Integration in Banach spaces and integration in R k and `1
(AUST, 20210510)

A Strong Convergence for the sum of three Monotone Operators in a Real Banach Space
(AUST, 20210709)Let E be a real 2uniformly 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 ForwardBackward Splitting Method Without Cocoercivity for the sum of two Monotone Operators in Banach Spaces
(AUST, 20210710)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 NonNewtonian/Newtonian Fluids Composite Reservoirs
(AUST, 20210403)During polymer flooding in the reservoir using shearthinning nonNewtonian fluids, an interface exists between the insitu Newtonian crude in the reservoir and the injected polymer solution. This work examines application ...

Prediction of Liquid Holdup for a MultiPlane System Using Artificial Neural Network
(AUST, 20201203)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, 20210402)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, 20210513)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 3D Polylactic Acid Scoffold
(AUST, 20210610)PolyLactic 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, 20200713)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, 20200802)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 ...
