In this paper the use of a design pattern fostering trust in mediated collaborative settings is described in the case of an European Virtual Seminar. Implementation experiences with and effects of the use of the design pattern are reported.

This paper presents a study investigating cooperation between players in casual games. Although widely used in co-located or asynchronous settings, cooperative gameplay elements are not popular in networked synchronous casual games. In our study, we have analyzed different types of cooperation between players in casual games. Each of these is based on a certain cooperative game design pattern, ...

We present a description and result of an ontology modeling process taken to the classroom. The application domain considered was cooking recipes. The modeling goal was to bridge heterogeneity across representational choices by developing a content ontology design pattern which is general enough to allow for the integration of information from different web sites. We will discuss the pattern de...

Curriculum proposals and counter proposals characterize technology education. Some proposals enjoy widespread attention, others attract only momentary notice. Considerable incongruity, moreover, sometimes exists between stated objectives and the methods proposed to achieve them (Clark, 1989). One source of uncertainty is the lack of clearly articulated curriculum designs. A curriculum design pa...

We present a new design pattern for high-performance parallel scientific software, named coalesced communication. This pattern allows for a structured way to improve the communication performance through coalescence of multiple communication needs using two communication management components. We apply the design pattern to several simulations of a latticeBoltzmann blood flow solver with stream...

The AnyLog pattern models the core knowledge of any Log, as a written record. The Log finds extensive use in the computing industry. The pattern makes it easy to model different kinds of logs rather than thinking of the problem each time from scratch. This pattern can be utilized to model any kind of log in any application and it can be reused as part of a new model.

We present a technique for formalizing design patterns using a technique based on attribute grammars. The technique allows design pattern applications to be identified in the source code, and supports automatic checking that the pattern is applied correctly. We expect the technique to be particularly useful when specializing frameworks built using design patterns.

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...
