— With the rise in complexity of modern systems, designers are spending a significant time on at the system level of abstraction. This paper introduces Model Algebra, a formalis...
View merging, also called view integration, is a key problem in conceptual modeling. Large models are often constructed and accessed by manipulating individual views, but it is im...
Tools to design, analyse and evaluate user interfaces can be used in user interface design research and in interface modelling research. This demonstration shows two working syste...
Abstract. Generalising modules over associative rings, the notion of modules for an endofunctor of any category is well established and useful in large parts of mathematics includi...
