In quality control charts, the problem of determining the optimum process mean arises when the deviation of a quality characteristic in one direction is more harmful than in the opposite direction. The failure mode in these two directions is usually different. A great majority of researches in this area have considered asymmet-ric cost function for processes with single quality characteristics....

Given the pervasiveness of collaborative systems in contemporary organizations and society, this paper aims to present several quality characteristics of collaborative systems in order to reveal the social and technological requirements that need to be met in order for such systems to provide the desired results. Furthermore, this paper defines a set of metrics for assessing the performance of ...

In this review the quality properties of linseed oil for food uses are discussed as well as factors affecting this quality. Linseed oil has a favourable fatty acid composition with a high linolenic acid content. Linseed oil contains nearly 60% α-linolenic acid, compared with 25% for plant oils generally. The content of linolenic acid and omega-3 fatty acids is reported to be high in linseed gro...

In this paper, we outline more than a hundred characteristics and attributes for the domain of academic sites in order to show the quality requirement tree and a descriptive framework to specify them. These elements are used in a quantitative evaluation, comparison, and ranking process. The proposed Web-site Quality Evaluation Method (QEM) is a useful approach to assess the artifact quality in ...

Recently, non-destructive techniques such as the Vis / NIR spectroscopy have been used to evaluate the characteristics of maturation and quality of pears. The study aims to validate the readings by the Vis / NIR spectroscopy as a non-destructive way to assess the qualitative characteristics of pear cultivars 'Williams', 'Packams' and 'Carrick', produced according to Brazilian conditions. The ex...

Long-term trends in the clinical characteristics, quality of care, and outcomes for AMI over time from the health system perspective in geographically diverse populations are not well known. Methods and Results—The present study included 20 ...

The World Wide Web is a common method for obtaining information on autism spectrum disorders, however, there are no guidelines for finding websites with high quality. We conducted two studies examining the characteristics and/or quality of autism websites in 2009 and 2010. We found websites with a .gov top-level domain had a statistically significant association with high quality websites and w...
