are discharged to ensure the consistency between refinement levels and hence the system’s overall correctness. Here, we are concerned with the refinement of specifications using the EVENT B modelling language and its associated toolset, the RODIN platform. In particular, we focus on the final steps

Our estimate of this slope, jump t , is defined via where F is the at-the money strike price, which equals the current futures price. We choose to look at the implied volatility at K = .9F because we do not want 6 to extrapolate the quadratic

Abstract-In this paper, we demonstrate how model checking can be used to verify safety properties for event-driven systems. SCR tabular requirements describe required system behavior in a format that is intuitive, easy to read, and scalable to large systems (e.g., the software requhements for the A

We extend this model by (a) introducing positive feedback of a set of neurons onto itself and (b

of encoding it is clear that image reconstruction must essentially be linear as well. That is, each of n V image values is to be calculated as a linear combination of sample values: where counts the voxels to be resolved. The transform F shall be referred to as the reconstruction matrix. Its size is n V ϫ n C
