This paper describes a validation architecture used within Intermountain Health Care's Clinical Knowledge Repository (CKR). The architecture provides additional functionality that complements XML Schema validation, producing user-friendly error messages and enabling validation rules reuse. The validation architecture helps document authors to fix their own errors. As a result, less than 1% of a...

by Raymond G. Lewis, PE In addition to potential business liabilities, there can be significant costs associated with an autoclave validation process. The practical experience that this article is based on may provide assistance in ensuring an effective, efficient validation process for steam sterilization. Introduction This article is based on practical experiences gained by the author while c...

Our first comment is on the optimization of the model parameter τ controlling the amount of noise in the augmented bootstrap method. In a supervised prediction problem, τ can and should be optimized using, e.g., a cross-validation (CV) procedure, as suggested by the authors. If the prediction accuracy is itself evaluated by cross-validation or a related approach, this yields a nested cross-vali...

BACKGROUND The increasing number of open-access ontologies and their key role in several applications such as decision-support systems highlight the importance of their validation. Human expertise is crucial for the validation of ontologies from a domain point-of-view. However, the growing number of ontologies and their fast evolution over time make manual validation challenging. METHODS We p...

clonidine hydrochloride is an antihypertensive agent used for migraine prophylaxis, attention deficit hyperactivity disorder, menopausal flushing and tourette syndrome. the quantity of the active substance in pharmaceutical preparations must be within specific limits, in agreement with the respective label claim. therefore, the aim of this study was to establish the conditions for two spectroph...

unlike teacher beliefs, there has been a dearth of study regarding efl learner beliefs. the reason can be that horwitz (1987) and the existing literature has predominantly been in an esl context. the present study reports the development and validation of a scale to measure the learner beliefs about language learning in iranian efl contexts. using a combination of verbal creativity method, inte...

water content plays an important role in the process of plant photosynthesis and biomass accumulation. many methods have been developed to retrieve canopy leaf water content from remote sensing data. however, the validity of these methods has not been verified, which limits their applications. this study estimates the leaf water content (lwc) of winter wheat with three most widely used indexes:...

objectives: mothers’ perception of their ability to parenting (maternal parenting self-efficacy) is a critical issue that influences their interactions with their preterm neonates. for better support of these mothers, a robust tool is needed which can measure mothers’ perception of their ability to understand and care for their preterm neonates as well as being sensitive to the various levels a...

Background: Schizophrenia is a mental disorder that severely affects the perception and relations of individuals. Nowadays, this disease is diagnosed by psychiatrists based on psychiatric tests, which is highly dependent on their experience and knowledge. This study aimed to design a fully automated framework for the diagnosis of schizophrenia from electroencephalogram signals using advanced de...
