A New Comment on Reinforcement of Testing Criteria
نویسندگان
چکیده
This paper presents the formal aspects of testing criteria for Safety Critical Systems. A brief review of testing strategies i.e. white box and black box is given along with their various criteria’s. Z Notation; a formal specification language is used to sever the purpose of formalization. Initially, the schemas are formed for Statement Coverage (SC), Decision coverage (DC), Path Coverage (PC), Equivalence Partition Class (EPC), Boundary Value Analysis (BV) and Cause & Effect (C&F). The completeness and correctness of test schema are enriched by verifying these with Z/EVES; a Theorem Prover tool for Z specification. Keywords—Formal Methods; Safety Critical System; Z Notation; Schema

Evaluating the Application of Reinforcement Correction Factor for Concrete Core Testing
This study investigates the reinforcement correction factor of concrete core in more detail to prepare appropriate outlines for interpretation of results. This investigation aims to minimize uncertainties involved to carry out the more realistic condition assessment of suspect buildings before taking up retrofitting/strengthening measures. For this purpose, an extensive experimental program inc...
متن کاملInnovative approach to strata reinforcement in coal mines with reference to evaluation cable bolts shear strength
There is an increasing need to determine accurately the strength properties of tendons for an effective ground control on mines and underground structures as well as on modelling simulations. The strength properties of cables, used as cable bolts, have been evaluated mainly by their ultimate tensile strength, as this kind of test can be carried out in the field as well as in the laboratory. Onl...

متن کاملNew Health Technologies: A UK Perspective; Comment on “Providing Value to New Health Technology: The Early Contribution of Entrepreneurs, Investors, and Regulatory Agencies”
New health technologies require development and evaluation ahead of being incorporated into the patient care pathway. In light of the recent publication by Lehoux et al who discuss the role of entrepreneurs, investors and regulators in providing value to new health technologies, we summarise the processes involved in making new health technologies available for use in the United Kingdom.
