Automated Pattern Detection and Generalization of Building Groups
… building group generalization by considering the detection of building patterns. Generalization is an important research field in cartography, which is part of map production and the basis for the derivation of multiple representation. As one of the most important features on map, buildings occupy …

Using Codecharts for formally modelling and automating detection of patterns with application to Security Patterns
Software design patterns are solutions for recurring design problems. Many have introduced their catalogues in order to describe those patterns using templates which consist of informal statements as well as UML diagrams. Security patterns are design patterns for specific security problems domains, …
