Thermal Challenges in Next-Generation Electronic Systems

Abstract: Thermal challenges in next-generation electronic systems, as identified through panel presentations and ensuing discussions at the workshop, Thermal Challenges in Next Generation Electronic Systems, held in Santa Fe, NM, January 7-10, 2007, are summarized in this paper. Diverse topics are covered, including electrothermal and multiphysics codesign of electronics, new and nanostructured materials, high heat flux thermal management, site-specific thermal management, thermal design of next-generation data centers, thermal challenges for military, automotive, and harsh environment electronic systems, progress and challenges in software tools, and advances in measurement and characterization. Barriers to further progress in each area that require the attention of the research community are identified.

Hair mercury levels in U.S. children and women of childbearing age: reference range data from NHANES 1999-2000.

Abstract: Exposure to methyl mercury, a risk factor for neurodevelopmental toxicity, was assessed in U.S. children 1-5 years of age (n = 838) and women 16-49 years of age (n = 1,726) using hair mercury analysis during the 1999-2000 National Health and Nutrition Examination Survey (NHANES). The data are nationally representative and are based on analysis of cross-sectional data for the noninstitutionalized, U.S. household population. The survey consisted of interviews conducted in participants' homes and standardized health examinations conducted in mobile examination centers. Distributions of total hair mercury levels expressed as micrograms per gram hair Hg and the association of hair Hg levels with sociodemographic characteristics and fish consumption are reported. Geometric mean (standard error of the geometric mean) hair mercury was 0.12 microg/g (0.01 microg/g) in children, and 0.20 microg/g (0.02 microg/g) in women. Among frequent fish consumers, geometric mean hair mercury levels were 3-fold higher for women (0.38 vs. 0.11 micro g/g) and 2-fold higher for children (0.16 vs. 0.08 microg/g) compared with nonconsumers. The NHANES 1999-2000 data provide population-based data on hair mercury concentrations for women and children in the United States. Hair mercury levels were associated with age and fish consumption frequency.

Image file storage and retrieval system

Abstract: A system which creates, stores, retrieves and displays thumbnail images. The dominant colors of the image are displayed in the thumbnail images. The dominant colors in an image are determined using groups of pixels where the average color is used to select an appropriate dominant color for display. The size of the thumbnails displayed and the area set for displaying the thumbnails can be changed to allow visual review of either a large number of thumbnails or a smaller but larger size set of thumbnails. Thumbnails, and other image files and other related text files and non-related files can be indexed and searched using keywords by using keyword views into the stored files to indicate a match when the views designate the same file. The system allows a search to be based on a partial match of keywords. Searching can be performed using super-keywords, which are combinations of keywords and other file and data characteristics. Super-keywords can be combined with other super-keyword or keywords for searching purposes. To facilitate multi-media storage and searching and integration of off-line media into the system, the system includes a master directory having a full directory containing entries of each media as a branch of the master directory tree. The system also includes the utilities necessary to create, access, retrieve and update local and network accessed remote files on any type of media.
