Quantum noise in X-ray image intensifiers.
Explicit expressions are given for the relative variance of the output screen of X-ray image intensifiers, and for detection quantum efficiency as a function of the technical features of the intensifier. The analysis takes into account all conversion stages and physical processes inside the image intensifier and includes a special treatment of scintillation. The results are analysed numerically...
متن کاملIntensifiers in German and Dutch Anaphor Resolution
information extend to other languages, and to further our understanding of the source/nature of these effects. The structure of this paper is as follows. In Section 1, we review existing work on the effects of structural and non-structural factors on the interpretation of pronouns and reflexives in PNPs, including our previous research on English (Kaiser, Runner, Sussman & Tanenhaus 2007, 2008)...
متن کاملA novel approach for distortion correction for X-ray image intensifiers.
Applications of X-ray image intensifiers in medical imaging, include the use of fluoroscopic projection images to generate three-dimensional tomographic reconstructions. Unfortunately, the inherent distortions on the acquired projections deteriorate the quality of the reconstructed tomograms. Distortion correction can be performed using algorithms that can be classified as global or local accor...
متن کاملA pr 2 00 4 WORD MAPS HAVE LARGE IMAGE
An element w in the free group on r letters defines a map fw,G: G r → G for each group G. In this note, we show that whenever w 6= 1 and G is a semisimple algebraic group, fw,G is dominant. As an application, we show that for fixed w and Γi a sequence of pairwise non-isomorphic finite simple groups, lim i→∞ log |Γi| log |f w,Γi (Γ r i )| = 1. Let Fr be the free group on r generators x1, . . . ,...
متن کاملExtremely costly intensifiers are stronger than quite costly ones
We show how the wide range in strengths of intensifying degree adverbs (e.g. very and extremely) could be explained by pragmatic inference based on differing cost, rather than differing semantics. This predicts a linear relationship between the meaning of intensifiers and their length and log-frequency. We test this prediction in two studies, using two different dependent measures, finding that...
