Minimal measurement error (reliability) during the collection of interval- and ratio-type data is critically important to sports medicine research. The main components of measurement error are systematic bias (e.g. general learning or fatigue effects on the tests) and random error due to biological or mechanical variation. Both error components should be meaningfully quantified for the sports p...
Work in safety management often involves classification of events using coding schemes or taxonomies . Such schemes contain separate categories, and users have to reliably choose which codes apply to the events in question. The usefulness of any system is limited by the reliability with which it can be employed, that is the consensus that can be reached on application of codes. This technical n...
Background Post-occlusive reactive hyperaemia (PORH) is a measurement of the vasodilatory capacity of the microvasculature that is associated with cardiovascular disease, peripheral arterial disease and foot ulceration. Reliability of its measurement in the toe for clinical and research purposes has not been adequately assessed. This study assesses both the intra and inter-tester reliability of...
Response inhibition plays a critical role in adaptive functioning and can be assessed with the Stop-signal task, which requires participants to suppress prepotent motor responses. Evidence suggests that this ability to inhibit a prepotent motor response (reflected as Stop-signal reaction time (SSRT)) is a quantitative and heritable measure of interindividual variation in brain function. Althoug...
• More accurately focus scarce fault identification resources on those portions of a software system most in need of it. • Estimate and forecast the risk of exposure to residual faults in a software system during operation, and develop risk and safety criteria to guide the release of a software system to fielded use. • Estimate the efficiency of test suites in detecting residual faults. • Estim...
BACKGROUND Inflammatory bowel diseases (IBD) are a group of inflammatory conditions of the colon and small intestine that may have critical consequences on patient's quality of life (QOL). Many disease-specific QOL tools have been developed recently. The McMaster Inflammatory Bowel Disease Questionnaire (IBDQ) is one of them. The aim of this study was to translate the IBDQ from English to Persi...
BACKGROUND The primary outcome measures for patients who undergo aesthetic facial procedures are quality of life and satisfaction with appearance. The FACE-Q, a new patient-reported outcome (PRO) instrument composed of independently functioning scales, is designed to measure a broad range of important outcomes in patients who undergo cosmetic surgical and/or nonsurgical facial procedures. OBJ...
Most LED manufacturers use units of luminous intensity (cd) for the measurement and classification of LED brightness. For numerous LED types, this procedure is reliable and reproducible. However, for LEDs with narrow emission angle characteristics, this method is inadequate. This application note describes the procedures for measuring luminous intensity, partial flux and luminous flux, along wi...
