Insights into the reliability of Ni/Cu plated p-PERC silicon solar cells Hasselt University KU Leuven Ghent University
Selective laser ablation of dielectric layers in combination with plated Ni/Cu/Ag contacts have been investigated by many photovoltaic researchers. Despite that there has been quite some practical progress on improved processing, the reliability of plated Ni/Cu/Ag cells still needs further insight and understanding. In this paper, the impact of laser induced defects that result from a ps-laser (wavelength 355nm) ablation on the performance of ...
What to expect from reliability and validity claims? A pragmatic conception of psychiatric nosology Ghent University
Static load bearing exercises of individuals with transfemoral amputation fitted with an osseointegrated implant: reliability of kinetic data Ghent University
A clinical test of lumbopelvic control : development and reliability of a clinical test of dissociation of lumbopelvic and thoracolumbar motion Ghent University

IMPROVING THE RELIABILITY OF VENOUS DOPPLER FLOW MEASUREMENTS: RELEVANCE OF COMBINED ECG, TRAINING AND REPEATED MEASURES Hasselt University
The nature of venous Doppler waves is highly variable. An additional electrocardiogram (ECG) improves the interpretation of venous Doppler wave characteristics and allows measurement of venous pulse transit time. The purpose of this study was to assess the reproducibility of ECG-guided repeated measurements of venous Doppler flow characteristics before and after sonographer training and the inter-and intra-observer variability. In four groups of ...
A Unified Approach to Multi-item Reliability Hasselt University KU Leuven
P>The reliability of multi-item scales has received a lot of attention in the psychometric literature, where a myriad of measures like the Cronbach's alpha or the Spearman-Brown formula have been proposed. Most of these measures, however, are based on very restrictive models that apply only to unidimensional instruments. In this article, we introduce two measures to quantify the reliability of multi-item scales based on a more general model. ...
A family of measures to evaluate scale reliability in a longitudinal setting Hasselt University KU Leuven
The concept of reliability denotes one of the most important psychometric properties of a measurement scale. Reliability refers to the capacity of the scale to discriminate between subjects in a given population. In classical test theory, it is often estimated by using the intraclass correlation coefficient based on two replicate measurements. However, the modelling framework that is used in this theory is often too narrow when applied in ...
Auditory steady-state responses in normal hearing adults: A test-retest reliability study Ghent University
The test-retest reliability of the auditory steady-state response (ASSR) has received limited attention. Therefore, the aim was to assess the test-retest reliability of an 80-Hz multiple-ASSR system in normal-hearing subjects by a comprehensive set of statistical methods. Twenty-nine participants (15 females) aged between 18 and 30 years contributed to two sessions (test-retest), and the ASSR thresholds were determined with a descending search ...
