Computer Graphics Tools for Understanding Tensor-Valued Volume Data: A Painting Metaphor (CCR-96-19649, CCR-9996209). PI: David H. Laidlaw Amount: $139,620 Duration: April 1997 Jan 2001. In this project we developed visualization tools using concepts from oil painting, primarily layering and discrete brush strokes. The work was applied to multi-valued medical imaging data and to 2D fluid flow. ...

Abstract Environmental risks are one of the greatest threats in twenty-first century. Especially last years, cascading impacts and associated with such events have received great attention as economic losses consequences mounted their wake. As concerns about these ripple effects rising, strategies to prevent manage indirect urgent demand. However, currently barely considered most countries can ...

The current Internet is not well suited for the transmission of high quality video such as MPEG-2 because of severe quality degradation during network congestion episodes. One possible solution is the combination of layered video coding with the Differentiated Services (DiffServ) architecture; different video layers are mapped into different priority levels, and packets with different prioritie...

In cut-to-length mechanized forest harvest operations, trees are cut, delimbed, and bucked to standard lengths directly in the harvest block. This in-stand processing, generates harvesting residue composed of tree limbs, tops, and foliage, which is frequently placed on machine operating trails to prolong trail trafficability and protect forest soils against heavy loadings. These so-called brush...

PURPOSE To assess the plaque removal efficacy of an oscillating-rotating power brush relative to a newly-introduced sonic power brush. METHODS This study used a randomized, examiner-blind, single-center, two-treatment, parallel group 4-week design. Subjects with pre-existing plaque scores of at least 1.75 on the Turesky Modification of the Quigley-Hein Plaque Index (TMQHPI) were evaluated for...

This paper investigates the effect of inserting a ring type barrier on leakage flow of brush seals with different bristles clearances (the distance between bristle pack tip and rotor surface). The ring is placed on both upstream and downstream sides of the bristles. An axisymmetric CFD model is employed to calculate radial pressure distribution along backing plate, axial pressure variation on r...

OBJECTIVE Liquid-based cytology (LBC) for cervical screening is becoming increasingly used. Together with SurePath LBC, various collecting devices can be utilized, among which the Cervex-Brush is the most widely used. The new Rovers Cervex-Brush Combi combines the advantages of the Cervex-Brush with the EndoCervex-Brush increasing sampling of the endocervical canal. The objective of this study ...

Cross layering, the disregard of the well established layered architecture, attract current investigations in protocol design. This report gives a short overview about recent trends. We will examine possible concepts of cross layering, their problems in general as well as their chances based on an example.
