Many geographical applications deal with spatial objects that cannot be adequately described by determinate, crisp concepts because of their intrinsically indeterminate and vague ...
Topological relationships like overlap, inside, meet, and disjoint uniquely characterize the relative position between objects in space. For a long time, they have been a focus of...
The ability to treat code as data within a programming language is a powerful feature. Smalltalk introduces an object called a block that represents code as data. We propose a for...
The modularity of aspect-oriented programming (AOP) has been a controversial issue. To investigate this issue compared with object-oriented programming (OOP), we propose a simple ...
Topological predicates between spatial objects have always been a main area of research on spatial data handling, reasoning, and query languages. The focus of research has definit...
