A mathematical model is developed to predict the three-dimensional time-dependent flow of a nonNewtonian shear-thinning liquid coating on a non-planar substrate. The model employs the lubrication approximation and other simplifications. Results are compared with experimental observation of the drainage flow out of an axisymmetric indentation in a vertical substrate. A straightforward experiment...

Enterprise Architecture Management (EAM) is considered a means to support coordination in enterprises. However, coordination between heterogeneous stakeholder groups with different interests is a challenging task to achieve. In this paper, we take a game-theoretic perspective on coordination in organizations. We identify three coordination games from literature: (1) Matching game, (2) Battle of...

Reconciling requirements for (1) the efficient integration of independently developed and evolving components and (2) the evolution of systems built from such components requires novel architectural styles, standards and idioms. Traditional object-oriented approaches have proven inadequate. Two important new mechanisms supporting integration and evolution are dynamic interface negotiation and a...

Architectural patterns(styles) are important artifacts containing specialized design knowledge to build good-quality systems. Complex systems often exhibit several architectural patterns in their design which leads to the need of architectural pattern composition. Unfortunately, information about the composition of patterns tend to be vaporized right after the composition process which causes p...

An important way that the reliability of a software system is enhanced is through the implementation of specific run-time measures called runtime tactics. Because reliability is a system-wide property, tactic implementations affect the software structure and behavior at the system, or architectural level. For a given architecture, different tactics may be a better or worse fit for the architect...

This paper presents an architectural pattern for structuring adaptive applications using aspectoriented programming in order to obtain separation of concerns. It is composed of known and novel patterns organized so as to provide good maintainability and modularity. 1

This paper introduces an approach to describing and selecting design patterns for developing communication components of parallel programs. The approach uses the kind of communication requirements of the architectural pattern whose processing components have to be communicated, along with characteristics and features of the parallel hardware platform and programming language synchronisation mec...

The objective of the research is reveal the concepts and the items of architectural prototype. So, this research involves a review of several studies which tackled the type in architecture in general, and through the four stages of development of the concept in the theory and history of architecture according to the study of Historical Evolution of Type in Architecture (Abdul Aziz : 2007). This...

Although there are many formal representations of architecture, actually determining what an architecture should be when systems are merged is largely based on context and human intuition. The goal of this paper is to find a mathematical model which supports this context and determines the architecture when the systems have been merged. A category of architectural models is presented, and the p...

Architectural stability refers to the extent an architecture is flexible to endure evolutionary changes in stakeholders’ requirements and the environment. We assume that the primary goal of software architecture is to guide the system’s evolution. We contribute to a novel model that exploits options theory to predict architectural stability. The model is predictive: it provides “insights” on th...
