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 ...

Combination-control of two or more systems which may have important application in Josephson junction ratchet array, and other physical systems has not been explored. Most of the theoretical framework is on combination ...

Without accurate estimation of annular pressure losses it is possible to face serious problems that would yield to interruption in drilling operation and sometimes lead to the abandonment of the well. Therefore, exact ...

In this thesis, we implemented Point Distribution Model and basic Active Shape Model algorithm and contributed this to the AUST Computer Vision and Machine Learning code library. We applied the Active Shape Model to ...

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 ...

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 ...

Numerical simulators estimate the recovery volumes and the volume of fluids in-place in the reservoir as a function of time and space by solving complex partial differential fluid flow equations. For gas condensate reservoirs, ...

Conventional methods used in determining initial gas-in-place and reserves for a dry gas reservoir entails the use of P/z vs cumulative production data. In a normally pressured gas reservoir, the only important production ...

Hydrocarbon production in the petroleum industry is often constrained by reservoir heterogeneity, deliverability and capacity of surface facilities, also optimization technique in the petroleum industry requires execution ...

A huge amount of data is generated on daily basis. The generated data can be both structured and unstructured data. The sources from which most of the unstructured data are found are the dailies, social networks (posts ...

The Dykstra-Parson techniques stands as the most widely used waterflood methods. The authors developed a discrete, analytical solution from which waterflood performance parameters were determined. Reznik et al extended the ...

• Let H be a real Hilbert space. Let K, F : H → H be bounded, continuous and monotone mappings. Let {un }∞ and {vn }∞ be n=1 n=1 sequences in E defined iteratively from arbitrary u1 , v1 ∈ H by un+1 = un − βn (F un − ...

This thesis is a contribution to Control Theory of some Partial Functional Integrodifferential Equations in Banach spaces. It is made up of two parts: controllability and existence of optimal controls. In the first part, ...

This thesis deals with the control of non linear oscillations in plasma governed by a classical Van der Pol equation . The main interest devoted to such an investigation is that non linear oscillations in plasma is essential ...

This paper presents the effect of polymer concentration on the release of fungicidal antimicrobial (AM) agent to prolonging the shelf life of packaged food. This project aimed to produce and test AM films with varying ...

Achieving efficient control of electrons and nuclei in atoms and molecules with lasers has been a subject of great interest for decades, in Physics and in Chemistry. One of the current and challenging questions with the ...

Like any industry, the economic success of the oil and gas industry can be no swifter than its success in corrosion control/prevention. Some oil and gas industries operate in hostile offshore environment that harbors ...

The cost and losses associated with corrosion annually is approximately $ 276 billion or 3.1% of the GDP in the USA, 3 - 4% of GNP in Australia, Great Britain, Japan and other countries. The associated cost and losses ...
