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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

We theoretically investigated a phenomena arising from the interaction of femtosecond pulsed lasers with an Hydrogen atom. The phenomena of interest to us, is the High or der Harmonic Generation (HHG) of soft and hard-Xray ...

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 ...

This paper theoretically examines the impact of thermal buoyancy on human skin tissue’s blood flow, heat exchange and their interaction with the surrounding environment using a two phase mathematical model that relies on ...

The phase space representation of quantum mechanics are well known as powerful tools for studying the correspondence between the density operator and classical distributions in phase space. This representation, known as ...

In this research work, we study and analyse Hindmarsh-Rose neuronal system with time delay. Considering the fast sub-system of the model, all the possible non-negative equilibria are obtained and their local as well as ...

Let (X,d) be a Hadamard space and let D be its closed convex nonempty set. We studied countable family of multivalued demicontractive mappings {Ti} from D to C B(D) with constants {ki} ⊂ (0,1) and developed an iterative ...

In this research work, we propose a viscosity type iterative scheme and showed that the scheme converges strongly to the attractive point of further 2-generalized hybrid mapping in hyperbolic spaces. The result presented ...

Let E be a strictly convex real Banach space and let D ⊆ E be a non-empty closed convex subset of E. Let {T}i∈I be a finite family of quasi-nonexpansive multivalued map which are continuous with respect to the Hausdorff ...

Let H1 and H2 be two Hilbert spaces and Aj : H1 → H2 be bounded linear operators and Ui: H1 → 2H1, Tj : H2 → 2H2, 1 ≤ i ≤ n, 1 ≤ j ≤ r be two multi-valued demi-contractive operators with demi-contractive constants βi and ...

An underlying theorem due to Gauss and Lengendre asserts that for an over determined system, there are solutions that minimize kAx − bk 2 which is given by the generalized in-verse of the matrix A even when A is singular ...

The theory of analytic functions plays a central role in operator theory. It has been a source of methods, examples and problems, and has led to numerous important results. Weighted shifts (which we shall see in the sequel) ...

In recent time, one of the ways of optimizing hydrocarbon production is commingling production from stacked reservoirs. Commingled production refers to the production of hydrocarbon from two or more separate zones through ...

The understanding of the behaviour of vertical upward and downward two-phase flow in large diameter pipes is very important in chemical, petroleum and nuclear sector where safety is of utmost concern. This work helps to ...

Gas hydrate is one of the major plagues of gas wells in the industry, capital costs to prevent hydrate blockage in pipelines is an dissociation temperatures for the operating pressures. The model developed was tested on ...
