Over the past three decades, considerable effort has been devoted to the study of software architecture. A major portion of this effort has focused on the originally proposed view of four “C”s—components, connectors, configurations, and constraints—that are the building blocks of a system’s architecture. Despite being simple and appealing, this view has proven to be incomplete and has required ...

There is increasing interest in the use of design patterns for model transformations, and a number of such patterns have been proposed. In this paper we survey previous work on transformation design patterns, discuss one pattern in detail, and identify priorities for future research.

The networks of interdependencies in large-scale software systems are complex, difficult for designers and developers to understand, and are a significant driver of the costs to develop and maintain software systems. Interdependencies and the costs they drive result directly from design structures and yet a disproportionately small effort is allocated to the design phase within the lifecycle of...

Our work addresses the challenges arising in the development of self-adaptive software, which has to work autonomously in an unpredictable environment, fulfilling the objectives of its stakeholders, while avoiding failure. In this context we developed the Tropos4AS framework, which extends the AOSE methodology Tropos to capture and detail at design time the specific decision criteria needed for...

Information search is critical in most decision-making tasks. An important aspect of information search is the stopping rule used by the decision maker to terminate information acquisition. Decision-making problems may be usefully decomposed into design problems and choice problems. The distinction is critical because the goals of stopping behavior in the two types of problems are quite differe...

When the number of data used for an identification experiment is small, the data contain transient effects and these effects contribute to the accuracy of the identified model. Consequently, when designing the optimal input signal for an identification experiment in the case of small data set, these transient effects have to be taken into account. In this paper, we present a methodology for opt...

in this article, the effect of parameters like working gap, work piece rotational speed and material removal mechanism(injection of the sic abrasive slurry and al2o3, use of diamond paste as abrasive tool) in magnetic abrasive finishing process using designing of experiments on the external surface of cylindrical work pieces of stainless steel aisi 440c to get minimum surface roughness has been...
