: One of the main operations in conceptual 3D design is the rearrangement of single and composite objects. This paper presents a new conceptual 3D design system that affords easy m...
Tropes, an object-based knowledge representation system, has been added three important intertwined features: constraints, composite objects and tasks. Constraints provide a decla...
We present a simple approach for implementing flexible locking strategies in a system of components, which may themselves be composite objects. The approach is flexible in that a ...
Convolution kernels, constructed by convolution of sub-kernels defined on sub-structures of composite objects, are widely used in classification, where one important issue is to ch...
