Traceability is an important concern in projects that span different engineering domains. Traceability can also be mandated, exploited and managed across the engineering lifecycle, and may involve defining connections between heterogeneous models. As a result, traceability can be considered to be multi-domain. This thesis introduces the concept and challenges of multi-domain traceability and ex...

This technical report offers a vision for traceability in software and systems engineering and outlines eight challenges that need to be addressed in order to achieve it. One of these challenges is referred to as the grand challenge of traceability because making traceability ubiquitous in software and systems development (traceability challenge eight) demands progress with all seven other chal...

Requirements traceability, regardless of the process used to produce a software system, is an important quality attribute for the resulting software product. However, existing approaches to achieving requirements traceability have been specifically designed for traditional software development with formal requirements processes. With the wide industry adoption of agile development methodologies...

A statistical approach to behavioral modeling for assessing dynamic metrological performance during the concept design of accurate digitizers is proposed. A surface-response approach based on statistical experiment design is exploited for avoiding unrealistic hypothesis of linearity, optimizing simulation, exploring operating conditions systematically, as well as verifying identification and va...

The prominent development of health technologies of the 20 century triggered demands for metrological reliability of physiological measurements comprising physical, chemical and biological quantities, essential to ensure accurate and comparable results of clinical measurements. In the present work, aspects concerning metrological reliability in premarket and postmarket assessments of medical de...

General metrological inspection planning is among the least explored CAPP domains. This paper explores certain basic issues involved in inspection planning using case-based reasoning in an environment of a Generic CAPP Support System. Firstly, algorithmic methods for characterizing and extracting inspection features are proposed and discussed. A sequential knowledge based filtering method is de...

In this paper, we present an enhancement input in the traceability model of digital forensic investigation. Plus, we present a literature review about existing traceability models. Furthermore, the outcome of this model expected to help and improvise the traceability model with theoretically proven justifications. Keywords—Forensic, traceability, Scenario, Evidence

A metrological atomic force microscope (AFM) with 50mm×50mm×2mm scan range has been designed and constructed. In this paper, the structure and preliminary results are introduced. The precise movement of the sample is driven by a piezoelectric motion stage and airbearing stage for different scanning range. Four multi-pass homodyne interferometers attached to the metrological frame measure the re...

The paper presents principle of operation and design of the most popular chemical sensors for measurement of volatile organic compounds (VOCs) in outdoor and indoor air. It describes the sensors for evaluation of explosion risk including pellistors and IR-absorption sensors as well as the sensors for detection of toxic compounds such as electrochemical (amperometric), photoionization and semico...

Production, characterization and certification of reference materials (RMs) are key activities in ensuring the metrological traceability measurement results various industries. One sources RM uncertainty is standard due to heterogeneity. Estimation based on analysis-of-variance method accordance with GOST 8.531-2002, ISO Guide 35:2017. The main difference between developed algorithms 35:2017 el...
