FunnyQT1 is a new model querying and transformation approach which is implemented as an API for the functional, JVM-based Lisp-dialect Clojure. It provides several sub-APIs for implementing different kinds of queries and transformations. For example, there is a model-to-model transformation API, and there is an in-place transformation API for writing programmed graph transformations. FunnyQT cu...

The relational model developed for the Integrated Relational Model of Installed Systems (IRMIS) toolkit has been successfully used to capture the Advanced Photon Source (APS) control system software (EPICS process variables and their definitions). The relational tables are populated by a crawler script that parses each Input/Output Controller (IOC) start-up file when an IOC reboot is detected. ...

This paper presents a formal modeling paradigm that is callable from C, the dominant language for embedded systems programming, for message passing APIs that provides reasonable assurance that the model correctly captures intended behavior. The model is a suitable reference solution for the API, and it supports putative what-if queries over API scenarios for behavior exploration, reproducibilit...

We represent a theory of (a fragment of) Isabelle/HOL in Isabelle/HOL. The purpose of this exercise is to write packages for domain-specific specifications such as class models, B-machines, . . . , and generally any languages that can be described with a sequence of “datatype” in HOL itself; the Isabelle code-generator can then be used to generate tactic code. Consequently the package is geared...

The need to manually specify temporal properties of software systems is a major barrier to wider adoption of software model checking, because the specification of software temporal properties is a difficult, time-consuming, and error-prone process. To solve this problem, we propose to automatically extract temporal specifications from code. Our approach uses a model checker to check a set of AP...

Verification back ends such as SMT solvers are typically highly complex pieces of software with performance, correctness and robustness as key requirements. Full verification of SMT solvers, however, is difficult due to their complex nature and still an open question. Grammar-based black-box input fuzzing proved to be effective to uncover bugs in SMT solvers but is entirely input-based and rest...

The Generic Security Services API (GSS-API) provides a naming architecture that supports name-based authorization. GSS-API authenticates two named parties to each other. Names can be stored on access control lists (ACLs) to make authorization decisions. Advances in security mechanisms and the way implementers wish to use GSS-API require this model to be extended for the next version of GSS-API....

The Extensible Markup Language (XML) consists of two Application Programming Interface (API) i.e. Document Object Model (DOM) and Simple Application of XML (SAX). Previous research has used the DOM API in the Leave Application prototype. In this research, the DOM API based code that developed in the prototype will be changed to SAX API based code. The performance measurement then is carried out...
