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...

The study entitled Women's Language Features on Utterances of Charlie's Angels Movie seeks to examine women's language features and the reasons using by three main women character. data was taken from utterances (2019) movie. researchers used Lakoff's hypothesis investigate features. Lakoff (1975) suggested ten for women, but this analysis only found nine in movie, namely lexical hedges or fill...

Image intensifiers suffer from distortions due to magnetic fields. In order to use this X-ray projections images for computer-assisted medical interventions, image intensifiers need to be calibrated. Opaque markers are often used for the correction of the image distortion and the estimation of the acquisition geometry parameters. Information under the markers is then lost. In this work, we cons...

We present two methods for determining the sentiment expressed by a movie review. The semantic orientation of a review can be positive, negative, or neutral. We examine the effect of valence shifters on classifying the reviews. We examine three types of valence shifters: negations, intensifiers and diminishers. Negations are used to reverse the semantic polarity of a particular term, while inte...

Mobile image intensifiers are more readily used to assess acetabular cup placement when performing a total hip arthroplasty through a direct anterior approach. However, patient positioning affects pelvic tilt and rotation, which in turn requires proper C-arm fluoroscopy adjustments for image interpretation. The authors provide insight into the interpretation of acetabular cup positioning based ...

Lakoff (1975), a pioneering study of women’s language, suggested a tendency for women to use more of hedges and intensifiers. Subsequent studies still attract some opposing (Fahy, 2002; Nemati and Bayer, 2007) or reinforcing (Bradac et al., 1995; Navalainen, 2008) views. This paper shows how a key word analysis offers an empirical evidence on the use of intensifying adverbs in male and female s...
