Anti-patterns, one of the reasons for software design problems, can be solved by applying proper design patterns. If anti-patterns are discovered in the design phase, this should lead an early pattern recommendation by using relationships between antiand design patterns. This paper presents an idea called Antipattern based Design Pattern Recommender (ADPR), that uses design diagrams i.e. class ...

Design patterns are widely accepted as elements of best practice. We have previously shown that these benefits can be amplified by supplementing informal pattern descriptions with precise pattern contracts, and monitoring tools that identify runtime contract violations. In this paper, we present a parallel approach to monitoring pattern contracts that reduces the performance impact of runtime m...

Design for change is one of the important themes of design patterns. Each design pattern normally embeds some specific ways for future changes. Currently, such evolution information is typically documented in each design pattern implicitly. In this paper, we classify design pattern evolutions into two levels: the primitive-level and pattern-level evolutions. Each pattern-level evolution is repr...

This paper proposes a new interpretation of stigmergy, where cooperation between production actors is achieved thanks to attributes (informational pheromones) attached to products. From this interpretation is introduced a new design pattern that can be used to develop product-driven systems. Agent-oriented components which implement it are presented, and then applied on an experimental platform.

In this work we discuss an ontology design pattern for material transformations. It models the relation between products, resources, and catalysts in the transformation process. Our axiomatization goes beyond a mere surface semantics. While we focus on the construction domain, the pattern can also be applied to chemistry and other domains.

Abstract. With serious games (SG) design it is difficult to offset fun and learning, especially when commercial partners, with different goals and methods, are involved. To produce an effective combination of fun and learning, we present our Design Pattern Library to address this issue. This library is aimed to help teachers fully take part in serious game design and to encourage mutual underst...

The purpose for this article is to explore technology education from the perspective of the academic rationalist. Such an exploration is intended to provide information for technology educators who are grappling with education reform since it appears that the reforms of the 1980s are based on academic rationalism curriculum theory. This exploration includes consideration of the theoretical pers...

While software design patterns are a generally useful concept, they are often (and mistakenly) seen as ready-made universal recipes for solving common problems. In a way, the danger is that programmers stop thinking about their actual problem, and start looking for pre-cooked solutions in some design pattern book instead. What people usually forget about design patterns is that the underlying p...
