Quality inspection in polymer processing by a thermophysical handy tester

HEAT TRANSFER - ASIAN RESEARCH (FORMERLY HEAT TRANSFER-JAPANESE RESEARCH), Issue 6 2006
Yasuyuki Koshikawa
Abstract This paper presents the applicability of a thermophysical handy tester for quality inspection and diagnostic technique such as in situ measurement of polymeric resin products. Influence of crystallinity known as a rating factor of quality, or filler concentration upon thermal conductivity is determined for the case of unsaturated polyester resin products by using the tester. Consequently, good correlations between the thermal conductivity and the crystallinity or the filler concentration are certified. The variation or the distribution of thermal conductivity of products molded under various conditions can be detected nondestructively using the tester. As an example, the thermal conductivity distribution around the forming gate is demonstrated, indicating the density-uniformity of the resin product. © 2006 Wiley Periodicals, Inc.

Representation of the subjective evaluation of the fabric hand using fuzzy techniques

INTERNATIONAL JOURNAL OF INTELLIGENT SYSTEMS, Issue 3 2003
Xianyi Zeng
This article presents a fuzzy logic,based method for representing and analyzing results of subjective evaluation on the fabric hand given by experts in fashion or quality inspection. This method permits the generation of a quantitative criterion characterizing the quality of textile products and modeling relationships between the subjective fabric hand evaluation and objective numerical data measured on the Kawabata evaluation system (KES). © 2003 Wiley Periodicals, Inc.

Spatially resolved characterization of silicon as-cut wafers with photoluminescence imaging

PROGRESS IN PHOTOVOLTAICS: RESEARCH & APPLICATIONS, Issue 4 2009
Johannes A. Giesecke
Abstract The characterization of silicon as-cut wafers is important for process control in solar cell production, since it can serve as starting material quality inspection and give information about a change of material properties caused by different process steps. In particular, spatially resolved characterization tools such as Photoluminescence Imaging (PLI) are useful as an information source. Due to the low signal in a luminescence image of an as-cut wafer a major problem is superimposed laser reflection light if the detection occurs from the illuminated side of the wafer. We present a method which eliminates the spurious reflection contribution by a special image correction technique. The image correction is based on a separate measurement of a reflection topography of the as-cut wafer surface. Additionally we show that for non calibrated luminescence images of as-cut material the bulk lifetime in low quality areas can be estimated by relating PL-intensity in these areas to a saturated PL-intensity value that can be assigned to high quality areas via a simulated curve of relative PL-intensity over minority carrier bulk lifetime.

An inspector calls: farm accommodation providers' attitudes to quality assurance schemes in the county of Devon

INTERNATIONAL JOURNAL OF TOURISM RESEARCH, Issue 6 2002
Rachel Hill
Abstract Estimates suggest that 10,000 farms in the UK offer bed and breakfast (B and B) serviced accommodation. A thorough review of the existing literature indicates over 50% of Devon and Cornwall's farmhouse B and B sector operate without participating in any form of quality assurance inspection scheme. This research executes a stratified postal survey to gain a comprehensive understanding of Devon's farmhouse B and B product, with particular interest in extracting providers' attitudes towards quality assurance inspection schemes. The very representative results suggest a divergence of attitudes towards the notion of quality inspections for all farmhouse B and B providers. Copyright © 2002 John Wiley & Sons, Ltd. [source]
