A Modified Subgradient Extragradeint Method for Variational Inequality Problems and Fixed Point Problems in Real Banach Spaces
(20171218)Let E be a 2uniformly 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 non expansive. An algorithm for ...

Spectral Decomposition of Compact Operators on Hilbert Spaces
(20171123)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 ...

Weak and Strong Convergence Theorems for Nonspreading type Mapping in a Hilbert Spaces
(20171218)The work of Osilike and Isiogugu, Nonlinear Analysis, 74 (2011), 18141822 on weak and strong convergence theorems for a new class of kstrictly pseudononspreading mappings in real Hilbert spaces is reviewed. We studied ...

Biomechanics of Surface Runoff and Soil Water Percolation
(20190623)In this study, the complex interaction of surface runoff with the biomechanics of soil water transport and heat transfer rate is theoretically investigated using mathematical model that rely on the two phase flows of an ...

Structural, Electronic and Optical Properties of Cu 2 Sns 3 Solar Absorber: A FirstPrinciple Density Functional Theory Investigation
(20190623)The development of inexpensive, nontoxic, high efficiency and earthabundant solar absorbers is critical for terawatt scale implementation of photovoltaics. Cu 2 SnS 3 is a promising earth abundant absorber material that ...

Pulsed Lasers in Lidar Application: Models for Optimizing Wind Turbine Performance
(20190622)Since the appearance of the first wind turbines at the end of the nineteenth century, wind energy has been considered to be a renewable energy source for not just developed countries but also developing countries as well. ...

Theoretical Study of CurrentInduced Dynamics of an Antiferromagnetic Skyrmionium
(20190622)In this thesis, we present a theoretical study on the currentinduced nucleation and propagation of antiferromagnetic skyrmionium. A skyrmionium, also known as 2πskyrmion, is a vortexlike magnetic structure characterized ...

Topological Antiferromagnetic Magnons
(20190712)We have studied a model for a noncollinear but coplanar antiferromagnetic spin texture on a two dimensional kagome lattice structure in the presence of DzyaloshinskiiMoriya Interaction (DMI). We observed some interesting ...

Fiscal System Design and Economic Evaluation for Petroleum Resource Development in Ghana
(20190612)Petroleum fiscal regime defines the extent to which the host government and the prospective investor can apportion risks and share project rewards. Ghana’s petroleum industry has become an attractive place for most investors ...

Comparative Analysis of Barite Production in Africa
(20190612)Successful oil and gas well drilling require hole stabilization. Barite comprised of barium sulphate is a common mineral chiefly used by oil and gas companies in their drilling operations. Barite is used in the drilling ...

Observatory System for Monitoring Electric Power Demand and Delivery
(20171122)Nigeria is a fastgrowing country in terms of urbanization. One of the major infrastructure challenge is power supply. However, this challenge is often not as a result of power generation but as a result of power distribution. ...

Genetic units Based Reservoir Characterization using a Normalized Pore Throat Radius for the Clastic System: Niger Delta as Field Case Study
(20161215)Globally, 30–50% of hydrocarbon volumes in siliciclastic reservoirs are contained within the thinbedded pay. In the Niger Delta deep water assets, over 30% of inplace volumes are found within the complex turbidites. The ...
