In this paper we introduce the concept of a Quasi-Birth-and-Death process (QBD) with Rational Arrival Process components. We use the physical interpretation of a Rational Arrival Process (RAP), developed by Asmussen and Bladt, to consider such a Markov process. We exploit this interpretation to develop an analytic method for such a process, that parallels the analysis of a traditional QBD. We d...

Analysis of the laminated composite plates under transverse loading is considered using the new method of Isogeometric Analysis (IGA). Non-Uniform Rational B-Splines(NURBS)are used as shape functions for modeling the geometry of the structure and also are used as shape functions in the analysis process. To show robustness of the new technique, some examples are represented and are compared with...

Drawing on arguments from institutional theory, we examine the implementation and use of a supplier development program by a major North American automotive manufacturer. While all suppliers adopted the program as an apparent response to coercive institutional pressures from their customer, the study focuses on the effects of such pressures on internal information processing and the behavior of...

Part I included a discussion of systems, the challenges facing the modern systems developer and how RUP SE addresses them, RUP SE Unified Modeling Language (UML)-based modeling and requirement specification techniques, and the use of UML semantics. This month, in Part II, we will focus on system architecture and introduce the RUP SE architecture framework, which describes the internals of the s...

rational functions are of great interest to engineers and geoscientists. the rational polynomial coefficient (rpc) model as a generalized sensor model has been introduced as an alternative for the rigorous sensor model of the satellite imaging. numerical instability of normal equations is the only single obstacle to the implementation of these functions. practically, estimating rational functio...

The literature on Object-Oriented software development processes has proposed a lifecycle which is often found to be at odds with the established software engineering processes of organizations. In particular, more established software engineering processes at higher CMM (Capability Maturity Model) levels often have deep roots in the ‘Waterfall’ lifecycle Some of these mature processes might be...

It is inconceivable how chaotic the world would look to humans, faced with innumerable decisions a day to be made under uncertainty, had they been lacking the capacity to distinguish the relevant from the irrelevant—a capacity which computationally amounts to handling probabilistic independence relations. The highly parallel and distributed computational machinery of the brain suggests that a s...

Considering the problems facing contemporary architecture in Iran, a better understanding of the meaning of architecture has become necessary. Architecture, like language, defines and facilitates the relationship between Man and his environment. The word architecture both in Arabic (Amara) and in Latin (Architecture), attempts to define the attributes of the maker before determining the char...
