We discuss a physical implementation of the Crystalline robot system. Crystalline robots consist of modules that can aggregate together to form distributed robot systems. Crystall...
A path dictionary encodes the connections among objects in the aggregation hierarchy. It has been shown to be an efficient mechanism for supporting nested object queries [6]. In t...
The design of the POSTGRES data model is described. The data model is a relational model that has been extended with abstract data types including user-defined operators and proce...
We formulate loop formulas for logic programs with arbitrary constraint atoms, for the semantics based on conditional satisfaction. This provides a method for answer set computati...
We propose a kernel convolution method to predict similar locations (wormholes) based on human travel behaviour. A scaling parameter can be used to define a set of relevant users t...
