Modeling the environment of a design module under verification is a known practical problem in compositional verification. In this paper, we propose an approach to translate an ACTL specification into such an environment. Throughout the translation, we construct an efficient tableau for the full range of ACTL and synthesize the tableau into Verilog HDL behavior level program. The synthesized pr...

Repricing of an employee stock option refers to the practice of lowering the strike price and /or extending the maturity date of a previously granted employee stock option. Normally, firms reprice after a period of significant stock price decline that renders the employee stock options deeply out-of-the-money. By modeling various repricing mechanisms based on some form of Brownian functional of...

We summarize and reorganize some of the last decade's research on real-time extensions of temporal logic. Our main focus is on tableau constructions for model checking linear temporal formulas with timing constraints. In particular, we nd that a great deal of real-time veri cation can be performed in polynomial space, but also that considerable care must be exercised in order to keep the real-t...

We extend the unquantiied set-theoretic fragment discussed in 1] with a restricted form of quantiication, we prove decidability of the resulting fragment by means of a tableau calculus and we address the eeciency problem of the underlying decision procedure, by showing that the model-checking steps used in 1] are not necessary.

In chemical analysis made by laboratories one has the problem of determining the concentration of a chemical element in a sample. In order to tackle this problem the guide EURACHEM/CITAC recommends the application of the linear calibration model, so implicitly assume that there is no measurement error in the independent variable X. In this work, it is proposed a new calibration model assuming t...
