We describe the Metro toolkit, which supports software modelling and analysis for requirements notations that have configurable semantics. Metro is based on a formalism, called template semantics, which structures the operational semantics of a family of notations as a predefined parameterized template that is instantiated with user-provided parameter values. Thus, the semantics of a single not...

In our previous work, we formally validated the correctness of a translation from a subset of Accellera’s Property Specification Language (PSL) to linear temporal logic (LTL) using the HOL theorem prover. We also built an interface from HOL to the SMV model checker based on a formal translation of LTL to ω-automata. In the present paper, we describe how this work has been extended and combined ...

Soybean Mosaic Virus (SMV) is one of the most important soybean diseases in world, and it seriously affects yield quality. In this paper, 405 SSR molecular markers were used genome-wide scan to analysis 327 varieties North China. The purpose was search genetic loci excellent resistance genes related SMV1 SMV3, reveal differences between models varieties. results confirmed that among tested larg...

This paper describes a method for automatic generation of tests from specifications written in Statecharts. These tests are to be applied to an implementation to validate the consistency of the implementation with respect to the specification. For test coverage, we adapt the notions of control-flow coverage and data-flow coverage used traditionally in software testing to Statecharts. In particu...

While autonomous systems offer great promise in terms of capability and flexibility, their reliability is particularly hard to assess. This paper describes research in the use of model checking to support the development of reliable autonomy software. In particular, it presents tools and techniques that we are developing to facilitate the integration of model checking into the main software dev...

In this paper a graphical editor to design Programmable Logic Controller (PLC) programs using Signal Interpreted Petri Nets (SIPN) is presented. SIPN are an extension of condition event Petri nets that allow the handling of input and output signals. The presented tool, SIPN Editor, has been developed using DiaGen which is an environment for rapidly developing diagram editors from a formal speci...

BACKGROUND Pancreatoduodenectomy (PD) is an extensive surgery, and its complications are grave. Acute ischemia of the jejunal loop due to thrombosis of the superior mesenteric vein (SMV) and its branches is one of the most dangerous complications that, although rare, if left untreated leads to abdominal sepsis and death of a patient. CASE PRESENTATION A 77-year-old man underwent PD for pancre...
