Design patterns have proven to be very useful for the design of object-oriented systems. The power of design patterns stems from their ability to provide generic solutions to reappearing problems that can be specialised for particular situations. The implementation of design patterns, however, has received only little attention and we have identified four problems associated with the implementa...

A developer of user interfaces (UI) should be able to employ a user interface pattern language to design acceptable user interfaces. But, what makes a good pattern language? Three types of validation were identified as requiring consideration: the validity of the individual patterns, the internal validation of the pattern language and the external validation of the pattern language. This paper ...

since language finds bureaucracy a kind of abuse by the public servants of the language and bureaucracy is considered by nature as a controversial speech, no desirable aspects could be found for it and no suitable model could be presented for a relatively negative phenomenon. that is why it is better to use the term 'post - bureaucratic language' instead of the phrase 'suitable m...

Learning to program involves the application of programming language features to the solving of novel problems, and the experience of educators suggests that it is this factor that causes novice programmers the most difficulty. Because software patterns are descriptions of common problems and their solution written in a standardised format that facilitates reuse, their use in the novice context...

Over the past ten years, a lot of advances have been made in both the learning design and learning analytics research communities in terms of research outputs. On the other hand, these advances have not made visible impact on the everyday practices of the key stakeholders they aim to serve: teachers and learners. This paper argues that to advance both fields and to connect them into an iterativ...

This paper presents the pattern language for architecture of communication protocols. This is a pattern language that aids a developer faced with the task of designing a networked system for the very first time. The pattern language has to parts: one for communication protocol specification and one for communication protocol design. The part for communication protocol specification contains pat...

This paper presents a new pattern language, PALM, for describing patterns in molecular biology sequences. The language is intended for representing knowledge about such patterns in a declarative, clear and concise way. It is also shown that its expressive power enables the definition of any regular or context free language, and also higher languages in the Chomsky hierarchy by parameter attachm...

Many services in a distributed public network like the Internet require secure communications. Security in communications consists of confidentiality, integrity, authenticity, and non-repudiability. These aims can be achieved with cryptography. Key management plays a fundamental role in secure communications, as it is the basis of all cryptographic functions. This paper describes a pattern lang...
