ABSTRACT 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 Topological (spin) Hall effect. our interest is on the effect of disorder (magnetic and non-magnetic) on transport of non-trivial topological textures. In these work we carry out a thorough study of the topological Hall and topological spin Hall effects and test t...
ABSTRACT Lanthanide complexes have been established as promising agents in their application as catalysts and photo-luminescent materials. Recent research has been geared towards the optical application of these lanthanide complexes, especially as organic light-emitting diodes (OLED) for TV screens, phones and other portable electronic devices. The luminescent ability of these complexes is largely dependent on the choice of ligand environment. We report here for the first time lanthanide comp...
ABSTRACT 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 semantics to perform sentiment analysis based on probabilistic graphical models and recurrent neural networks. In the empirical evaluation, the classification performance of the graphical models was compared with some traditional machine learning classifiers and a ...
Preeclampsia is a multisystem disease of pregnancy of unknown cause. It is a maternal syndrome, which is characterized by increased blood pressure, edema, proteinuria or significant amount of protein in the urine of pregnant women and abnormal clotting, liver and renal functions all of which may be due to the release of placental toxic factors into the mother’s circulation. The only effective therapy to this complication is to facilitate the culteinment of the pregnancy or delivery (in...
ABSTRACT Let E be a 2-uniformly convex and uniformly smooth real Banach space with dual space E ∗ . Let A : C → E ∗ be a monotone and Lipschitz continuous mapping and U : C → C be relatively nonexpansive. An algorithm for approximating the common elements of the set of fixed points of a relatively nonexpansive map U and the set of solutions of a variational inequality problem for the monotone and Lipschitz continuous map A in E is constructed and proved to converge strongly.
ABSTRACT The leading climate factors influencing availability of water are; temperature, relative humidity, precipitation, and evaporation. Water and agricultural production cycles are indisputably influenced by temperature and relative humidity. Temperature and relative humidity projections can therefore proficiently be employed in making decisions when optimal usage of water resources is of interest. Thus, the current study explored both the “long-run” and “short-run” impact of both...
ABSTRACT The effect of cell wall enzymes on the sugar composition of soymilk was investigated using High Performance Liquid Chromatography (HPLC) and UV/Visible spectrophotometer. Soymilk was extracted from wet milled soybean slurry from three different varieties of soybean (Samsoy1, Samsoy 2 and TGX). Different cell-wall degrading enzymes (glucanase, cellulase. arabanase, hemicellulase and xylanase) were applied to each batch of soybean slurry before extraction of soymilk. The enzym...
The study examines the relation between inflation and some key macroeconomic variables such as money supply, interest rate, exchange rate, and GDP in Ghana. These macroeconomic variables are obtained from the Bank of Ghana spanning through January 1990 to December 2014. Data obtained were on monthly basis. However, it is only the GDP which was an annual data but had been transformed into monthly data. We use the Augmented Dickey-Fuller (ADF) technique; the Granger Causality Test Techniqu...
ABSTRACT Compact operators are linear operators on Banach spaces that maps bounded set to relatively compact sets. In the case of Hilbert space H it is an extension of the concept of matrix acting on a finite dimensional vector space. In Hilbert space, compact operators are the closure of the finite rank operators in the topology induced by the operator norm. In general, operators on infinite dimensional spaces feature properties that do not appear in the finite dimension case; i.e matrices. ...
ABSTRACT Implementing Distributed Database Management System is often difficult due to the disruption of highly coordinated, interdependent processes (e.g.) information exchange, communications, relationships) of providing care in Road Safety. Thus, this system creates and maintains all offender data electronically. The system captures accident victim data, vehicle registration, driving license, and offenders, at its source at the time of entry using a graphical user interface having ...
The scope of Quadratic Form Theory is historically wide although it usually appears almost as an afterthought when needed to solve a variety of problems such as the classification of Hessian matrices in finite dimensional Calculus [1], [2], [3], the finding of invariants that fully describe the equivalence class of a given form in Algebraic Geometry and Number Theory [4], the use of Rayleigh-Ristz methods for finding eigenvalues of real symmetric matrices in Linear Algebra [5], [6], the secon...
ABSTRACT Throughout history, studies have amply revealed that where people choose to settle within the urban space is not new. This has been explained to be an important part of the urbanisation process. Effect of fear of crime on the urban environment especially that which involves the re-location of activities and the restructuring of the built environment as an impact factor response strategy is less acknowledged in urban security scholarship especially in developing countries. Rather, con...
ABSTRACT Taking Nigeria as a case study, most educational institutions, be it at the primary, secondary or tertiary level are faced with the challenge of over population of student’s in a single classroom. Also, the teacher who teaches an over populated class finds it quite difficult to have a one on one interaction or communication with each student in order to learning challenges. As a result of that, most students find it difficult to understand in the classroom. This research is concer...
ABSTRACT Algorithms for single-valued and multi-valued nonexpansive-type mappings have continued to attract a lot of attentions because of their remarkable utility and wide applicability in modern mathematics and other reasearch areas,(most notably medical image reconstruction, game theory and market economy). The first part of this thesis presents contributions to some crucial new concepts and techniques for a systematic discussion of questions on algorithms for singlevalued and multi-valued...
The most popular method for studying stability of nonlinear systems is introduced by a Russian Mathematician named Alexander Mikhailovich Lyapunov. His work ”The General Problem of Motion Stability ” published in 1892 includes two methods: Linearization Method, and Direct Method. His work was then introduced by other scientists like Poincare and LaSalle . In chapter one of this work, we focussed on the basic concepts of the ordinary differential equations. Also, we emphasized on relevant ...
