Model-based sparsity projection pursuit for lattice vector quantization
In this work we present an efficient coding scheme suitable for lossy image compression using a lattice vector quantizer (LVQ) based on statistically independent data projections...

Static analysis of atomicity for programs with non-blocking synchronization
In concurrent programming, non-blocking synchronization is very efficient but difficult to design correctly. This paper presents a static analysis to show that code blocks are ato...

Polytypic Syntax Tree Operations
Polytypic functional programming has the advantage that it can derive code for generic functions automatically. However, it is not clear whether it is useful for anything other tha...
