Executable formal speci cation can allow engineers to test (or simulate) the speci ed system on concrete data before the system is implemented. This is beginning to gain acceptance...
Conventional software engineering tends to focus on a small part of the software life cycle: the design and implementation of a product. The bulk of the lifetime cost is in the ma...
We propose and evaluate two indexing schemes for improving the efficiency of data retrieval in high-dimensional databases that are incomplete. These schemes are novel in that the ...
Temporal databases provide built-in supports for efficient recording and querying of time-evolving data. In this paper, data clustering issues in temporal database environment are...
Vector, emerging (homogenous and heterogeneous) multi-core and a number of accelerator processing devices potentially offer an order of magnitude speedup for scientific application...
