Formal certification of code-based cryptographic proofs
As cryptographic proofs have become essentially unverifiable, cryptographers have argued in favor of developing techniques that help tame the complexity of their proofs. Game-base...

Monadic datalog over finite structures with bounded treewidth
Bounded treewidth and Monadic Second Order (MSO) logic have proved to be key concepts in establishing fixed-parameter tractability results. Indeed, by Courcelle's Theorem we ...

An Energy-Conscious Exploration Methodology for Reconfigurable DSPs
As the "system-on-a-chip" concept is rapidly becoming a reality, time-to-market and product complexity push the reuse of complex macromodules. Circuits combining a varie...

An efficient wakeup design for energy reduction in high-performance superscalar processors
In modern superscalar processors, the complex instruction scheduler could form the critical path of the pipeline stages and limit the clock cycle time. In addition, complex schedu...

Logic-based ontology comparison and module extraction, with an application to DL-Lite
We develop a formal framework for comparing different versions of ontologies, and apply it to ontologies formulated in terms of DL-Lite, a family of `lightweight' description...
