Time-frequency analysis compensating missing data for Atrial Fibrillation ECG assessment
We propose a novel algorithm for temporal tracking of the fibrillatory frequency for Atrial Fibrillation (AF) ECG. Both Atrial activity extraction and fibrillatory frequency tra...

Programming the memory hierarchy revisited: supporting irregular parallelism in sequoia
We describe two novel constructs for programming parallel machines with multi-level memory hierarchies: call-up, which allows a child task to invoke computation on its parent, and...

Extended Computation Tree Logic
We introduce a generic extension of the popular branching-time logic CTL which refines the temporal until and release operators with formal languages. For instance, a language may ...

Hypothetical Reasoning from Situation Calculus to Event Calculus
Pinto and Reiter have argued that the Situation Calculus, improved with time handling axioms, subsumes the features of linear time temporal formalisms such as Event Calculus and I...

Comparing Subsumption Optimizations
Effective systems for expressive description logics require a heavily-optimised subsumption checker incorporating a range of optimisation techniques. Because of the correspondence...
