We study the potential contribution of governance theories to analysing the post-merger integration of the IS. We provide a clarifying overview of neoclassical theory of the firm, the nexus of contracts perspective, agency theory, early incomplete contracting literature, transaction cost economics and property rights theory, and discuss their contributions to the existence, boundaries and inter...

Permeability is the ability of porous rock to transmit fluids and one of the most important properties of reservoir rock because oil production depends on the permeability of reservoirs. Permeability is determined using a variety of methods which are usually expensive and time consuming. Reservoir rock properties with image analysis and intelligent systems has been used to reduce time and money...

Performance of a gas turbine mainly depends on the inlet air temperature. The power output of a gas turbine depends on the flow of mass through it. This is precisely the reason why on hot days, when air is less dense, power output falls. The objective here is to assess the advanced systems applied in reducing the gas turbine intake air temperature and examine the merits from integration of the ...

The healthcare industry is composed of primary and secondary healthcare providers. Each provider needs to exchange information with other providers. Information Systems (IS) developed on different types of hardware and software platforms serve this need. Due to the heterogeneous and distributed nature of information and communicating technology (ICT) in the healthcare industry, sharing of the d...

The efforts undertaken by healthcare organisations to modernise their services have resulted in the development of disparate Healthcare Information Systems (HIS). Systems heterogeneity has an impact on the quality of the services provided to patients. Thus, the integration of HIS will result in improvement of the quality of care provided to patients. Although healthcare organisations have turne...

In this paper, a numerical method for solving the constrained optimal control of time-varying singular systems with quadratic performance index is presented. Presented method is based on Bernste in polynomials. Operational matrices of integration, differentiation and product are introduced and utilized to reduce the optimal control of time-varying singular problems to the solution of algebraic ...

in this article, a numerical method based on  improvement of block-pulse functions (ibpfs) is discussed for solving the system of linear volterra and fredholm integral equations. by using ibpfs and their operational matrix of integration, such systems can be reduced to a linear system of algebraic equations. an efficient error estimation and associated theorems for the proposed method are also ...
