Visualization is the science of representing data visually in order to enhance communication or understanding. In this way, the complex and powerful capabilities of the human visual system can be harnessed to aid in the comprehension of potentially huge quantities of information. Since the information contained in visualizations must pass through the perceptual system, careful attention to the ...

Effective tools are crucial for visualizing large quantities of information. While developing these tools, numerous graph drawing problems emerge. We present solutions for reducing clutter in a radial visualization of a bipartite graph representing the alerts generated by an IDS protecting a computer network. Our solutions rely essentially on (i) unambiguous edge bundling to reduce the number o...

TomoTherapy Quality Assurance (TQA) is a software package developed to monitor certain aspects of machine performance. In this study, the TQA quantities or data trends most effective in monitoring energy drifts and magnetron stability were determined respectively. This retrospective study used data collected from three TomoHD units. The TQA modules investigated were Step-Wedge Helical, Step-Wed...

This work was to find out to what extent the knowledge of dependence of impedance on the crack depth observed by means of microwave frequencies can be used as nondestructive techniques for biocompatible materials which are used in bone replacement. The measured and calculated results are given in the graphic form and are compared each other in common graphs which provide a good overview about b...

There were 56 deaths following trauma in the adult Accident and Emergency Department of the University Hospital, Nottingham, over a 5-year period from 1983 to 1987. Forty-six of these deaths followed road-traffic accidents. The trauma deaths made up 16% of all adult deaths and 0.13 per thousand new attenders. We found evidence of inappropriate management in four cases, all relating to inadequat...

an efficient synthesis of methyl 2-[2-(alkylimino)-4-oxo-3-phenyl-1,3-thiazolan-5-yliden]acetate derivatives via simple three-component reaction and one-pot reactions between isoquinoline, dimethyl acetylenedicarboxylate and n-phenylthiourea under solvent-free conditions without using any additional catalyst, is described. the mild reaction conditions and good yields and exhibit the synthetic a...
