Variational Inequality in Hilbert Spaces and their Applications
(2019-06-23)
The study of variational inequalities frequently deals with a mapping F from a vector 0 space X or a convex subset of X into its dual X . Let H be a real Hilbert space and a(u, v) be a real bilinear form on H. Assume that ...
Effect of Disorder on Spin Transport in Topological Non-Trivial Magnetic Textures
(2019-06)
An effect that is observed when an electron passes through a non-collinear magnetic textures such as skyrmion, the electron gets deviated as a result of the fictitious magnetic field generated by the skyrmion giving rise to ...
Investigation of Peo-Polymer Blend Electrolytes for Electrochemical Capacitors
(2019-07-23)
Recently, there has been a drift of attention towards gel polymer based electrolytes owing to the fact that they are cheap and can achieve an extended potential window for improved energy density in s upercapacitor devices ...
Techno-Economic Feasibility of Ethane Based Enhanced Oil Recovery in Nigeria (CASE Study: Niger Delta)
(2017-12-15)
Increasing oil recovery has been one of the issues enlisted for attention in oil producing countries around the world for past decades. So many forms of oil recovery techniques have been considered; infill drilling of new ...
Assessment of Heavy Metal Pollution in Soil And Surface Water in Mng-Gold, Kokoya District, Bong County, Liberia
(2019-07-23)
The presence of heavy metals in water and soil by metalliferous mining activities at MNG-Gold Mine was fully investigated. The extraction of gold in recent years, has led to the generation of huge quantities of solid and ...
Investigation of Lead-Free Bismuth Perovskite by Numerical Simulation using Scaps
(2019-07-23)
The theoretical study of methylammonium bismuth halide, (CH 3 NH 3 ) 3 Bi 2 I 9 , was simulated using SCAPS 1D software package. The effect of the bismuth perovskite absorber layer thickness on the solar cell performance ...
Bioactive Polymer as an Alternative Binder for Electrochemical Capacitors
(2019-07-23)
Binders are important components of electrodes of supercapacitors because of their ability to adhere active components and make the resultant slurry to adhere on current collectors. This work seeks to investigate the ...
Substitutional and vacancy defects in two-dimensional AlSb: A first principle approach
(2019-07-23)
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 ...
Semantic Sentiment Analysis Based on Probabilistic Graphical Models and Recurrent Neural Networks
(2019-07-23)
Sentiment Analysis is the task of classifying documents based on the sentiments expressed in textual form, this can be achieved by using lexical and semantic methods. The purpose of this study is to investigate the use of ...
Automatic Detection of Injecton Attack in Http Requests
(2019-06-20)
Malicious user requests pose a vicious threat to backend devices which execute them; more so, could result in the compromise of other user accounts, exposing them to theft and blackmail. It becomes imperative to sanitize ...
