This article illustrates a model selection management approach for virtual prototypes in interactive simulations. In those numerical simulations, the virtual prototype and its environment are modelled as a multi-agent system, where every entity (prototype, human, etc.) is modelled as an agent. In particular, virtual prototyping agents that provide mathematical models of mechanical behaviour in ...

Formal methods tools have been shown to be effective at finding defects in safety-critical systems, including avionics systems in commercial aircraft. The publication of DO-178C and the accompanying formal methods supplement DO-333 provide guidance for aircraft manufacturers and equipment suppliers who wish to obtain certification credit for the use of formal methods for software development an...

The constant-rank condition for feasible points of nonlinear programming problems was defined by Janin (Math. Program. Study 21:127–138, 1984). In that paper, the author proved that the constant-rank condition is a first-order constraint qualification. In this work, we prove that the constant-rank condition is also a secondorder constraint qualification. We define other second-order constraint ...

every invention in order to be registered, should have essential conditions and the legal due process should be complied with. the novelty is a traditional qualification of any invention, which must be considered objectively; the applicant’s awareness or his ignorance in regard to it's public release, is not efficient in the maintenance or decline of invention’s novelty. the state of the a...
