This paper tackles the problem of the computation of a planar polygonal curve from a digital planar curve, such that the digital data can be exactly retrieved from the polygonal curve. The proposed transformation also provides an analytical modelling of a digital plane segment as a discrete polygon composed of a face, edges and vertices. A dual space representation of lines and planes is used t...

object: the gold standard for evaluating bone mineral density is dual energy x-ray absorptiometry (dexa).  prior studies have shown poor reliability using analog wrist x-rays in diagnosing osteoporosis. our goal was to investigate if there was improved diagnostic value to visual assessment of digital hand x-rays in osteoporosis screening. we hypothesized that similar to analog counterparts, dig...

The dual slope integrating analog to digital converter (ADC) is an efficient one for wireless transmission of ECG signals. Normally the dual slope ADCs are used for high resolution applications and the accuracy is very high. The main advantage of the ADC design is its high speed with low power. The dual slope ADC consists of integrator, comparator and a ten bit binary counter. To design integra...

One of the key reasons for deterioration antenna pointing accuracy radio telescopes is deformation and tilt alidades, which primarily result from track unevenness thermal gradients. A high-precision inclinometer measurement system installed to investigate alidade errors caused thermally. An environment control box with a leveling base was designed reduce interference external environment, prove...

Background: ‪Because of the proximity anatomical structures involved in auditory and vestibular functions, complications concerning inner ear may lead to problems involving both systems. This study investigated whether static balance knee proprioception deaf basketball players are different from those individuals with normal hearing. Material methods: ‪12 national 13 hearing were included. Stat...
