In this chapter we summarize the top research challenges in creating successful visualization tools for tensor fields in engineering. The analysis is based on our collective experiences and on discussions with both domain experts and visualization practitioners. We find that creating visualization tools for engineerMario Hlawitschka Department of Computer Science, Leipzig University, Leipzig, G...

We introduce a web-based, client-server computing infrastructure to assist the interactive navigation of large-scale astronomy observations. Large image datasets are partitioned into a spatial index structure that allows prefix-matching of spatial objects. In conjunction with pixel-based overlays, this approach allows fetching, displaying, panning and zooming of gigabit panoramas of the sky in ...

Climate change of the earth is a unanimously accepted reality and probably one of the most prominent challenges for scientists, development workers, policy makers and stakeholders. Average global temperature is likely to rise by 2 to 11.5 0 F and the predicted increase in CO2 level will be 800 ppm from the present 400 ppm by 2100 (IPCC, 2007). The rise in CO2 level increases heat stress. Change...

Background: Pulmonary vein isolation (PVI) is the cornerstone of atrial fibrillation (AF) ablation in both paroxysmal and persistent AF. However, this procedure is still challenging and time consuming. Objective: The aim of this study was to present our approach for PVI using a novel circular irrigated multielectrode mapping and ablation catheter (nMARQ) and to present acute and mid-term result...

Composition of milk fa t Cows’ milk fat consists mainly of triglycerides (98-99 g/100 g) together with smaller amounts of phospholipids (0 .9 ~ / I W g), cholesterol (0.3 g/100 g), carotenoids (6-7 pg/g), vitamin A (6-8 pg/g), vitamin D (0-5 pg cholecalciferoV1 oo g) and trace concentrations of other fat-soluble substances such as lanosterol, P-sitosterol, saturated hydrocarbons, squalene, glyc...

extended abstractintroductionin the past decades, development policies in the country have caused negativeeffects on regions. these policies have caused the mass evacuation of ruralsettlement and the imbalance hierarchy of settlements. the reflect of these policiesare visible in the rapid and uneven growth of large cities and eliminate loops linkingbetween cities and rural settlements from the ...
