It is critical to be able to achieve an acceptable quality level before a software package is released. It is often important to meet a target release date. To be able to estimate the testing efforts required, it is necessary to use a software reliability growth model. While several different software reliability growth models have been proposed, there exist no clear guidelines about which mode...

Although unavailability and failure frequency are both important reliability measures for designing telecommunications networks, having two different reliability measures causes difficulties when their evaluation results contradict each other. To overcome these difficulties, I propose an approach to determining a single reliability measure to be used. I focus on market share, which is a very im...

Speaker verification is a biometric identity verification technique whose performance can be severely degraded by the presence of noise. Using a coherent notation, we reformulate and review several methods which have been proposed to quantify the uncertainty in verification results, some with a view to coping with the effects of mismatched training-testing environments. We also include a recent...

This paper presents a new method for fuzzy system reliability analysis based on fuzzy semi-markov model with fuzzy transitions. The definition and the basic equation for interval transitions of a semi-markov model with fuzzy transitions are provided. The transitions for the above model with fuzzy states is provided for the non-homogeneous case. We apply this fuzzy technique to ATM transactions ...

The importance of compassion is widely recognized and it is receiving increasing research attention. Yet, there is lack of consensus on definition and a paucity of psychometrically robust measures of this construct. Without an agreed definition and adequate measures, we cannot study compassion, measure compassion or evaluate whether interventions designed to enhance compassion are effective. In...

BACKGROUND Self-management is important to the recovery and quality of life of people following stroke. Many interventions to support self-management following stroke have been developed, however to date no reliable and valid outcome measure exists to support their evaluation. This study outlines the development and preliminary investigation of the psychometric performance of a newly developed ...

OBJECTIVE To validate a useful version of the Motor Function Measure (MFM) in children with neuromuscular diseases aged <7 years old. DESIGN Two prospective cohort studies that documented the MFM completion of children aged between 2 and 7 years old. SETTING French-speaking rehabilitation departments from France, Belgium, and Switzerland. PARTICIPANTS Healthy children (n=194) and children...

BACKGROUND The validity of the Malnutrition Screening Tool (MST) in geriatric rehabilitation has been evaluated in a research environment but not in professional practice. OBJECTIVE In older adults admitted to rehabilitation, this study was undertaken to compare the MST scoring agreement (inter-rater reliability) between health professionals with and without malnutrition risk and screening tr...

Cognitive impairment is prevalent in schizophrenia and is related to poorer functional and treatment outcomes. Cognitive assessment is therefore now a routine component of clinical trials of new treatments for schizophrenia. The current gold-standard for cognitive assessment in clinical trials for schizophrenia is the MATRICS (Measurement and Treatment Research to Improve Cognition in Schizophr...
