Modern numerical process simulators are becoming increasingly complicated in both physical models and domain shape. Grid generation is difficult for these simulators because of the inherent transient nature of the problems being solved. This paper addresses adaptive grid refinement for use in solving diffusion problems. It additionally investigates higher(More)
BACKGROUND Although the outcomes of caustic ingestion differ between children and adults, it is unclear whether such outcomes differ among adults as a function of their age. This retrospective study was performed to ascertain whether the clinical outcomes of caustic ingestion differ significantly between elderly and non-elderly adults. METHODS Medical(More)
BACKGROUND To document the relationship between triage vital signs and in-hospital mortality among emergency department (ED) patients with acute poisoning. METHODS Poisoning patients who admitted to our emergency department during the study period were enrolled. Patient's demographic data were collected and odds ratios (OR) of triage vital signs to(More)
Mesh generation for process simulation is a difficult task, complicated by both the moving boundaries and the time dependence of the solutions. For both computational and ease of use reasons, automatic mesh generation and discretization error control is desirable. This paper describes an approach based on local error estimates to refine the mesh. This paper(More)
STUDY OBJECTIVE The progress of emergency medicine (EM) in Taiwan, China, and Hong Kong was evaluated from the perspective of publications in EM journals. METHODS This was a retrospective study. All articles published from 1992 to 2011 in all journals in the EM category in the 2010 Journal Citation Reports (JCR) were included. A computerized literature(More)
In this study, a spotlight filter for capturing the local structure information in tracing object's contour is proposed for object contour extraction. By searching the possible contour path between the initial source and destination contour points, the spotlight filter is able to capture the local structure information along the path, filter out the edge(More)
