Model Checking of Extended OCL Constraints on UML Models in SOCLe
We present the first tool that offers dynamic verification of extended traints on UML models. It translates a UML model into an Abstract State (ASM) which is transformed by an AS...

ParaScale: Exploiting Parametric Timing Analysis for Real-Time Schedulers and Dynamic Voltage Scaling
Static timing analysis safely bounds worst-case execution times to determine if tasks can meet their deadlines in hard real-time systems. However, conventional timing analysis req...

Faster and more accurate face detection on mobile robots using geometric constraints
— We develop a framework to allow generic object detection algorithms to exploit geometric information commonly available to robot vision systems. Robot systems take pictures wit...

Incremental Maintenance of Double Precedence Graphs: A Constraint-Based Approach
Reasoning on precedence relations is crucial for many planning and scheduling systems. In this paper we propose a double precedence graph where direct precedence relations are kep...

Time Recursive Petri Nets
Recursive Petri Nets (RPNs) allow to design and analyze complex discrete event systems. Indeed, RPNs enable to model patterns of discrete event systems related to the dynamic struc...
