In ISO9236-1 there is no description of the processing method for the sensitometric determination of an x-ray film by the film-screen combination method. But it states that when the film-screen combination system is being determined, either manual processing or automatic processing can be adopted. The different processing procedures will result in wide different sensitivities and average gradie...

We present a new software package for interactive segmentation of 3D images by geodesic snakes, with manual editing. Several variants of level set snakes are incorporated, including both gradientmagnitude based snakes as well as region-competition snakes. A complete segmentation pipeline, including image preprocessing, bubble initialization and parameter control, is provided in an intuitive use...

The analysis of hemispherical photographs is nowadays an established method for assessing light indirectly and describing canopy structures. In this article, we present an automatic threshold algorithm for separating canopy and sky by edge detection. The algorithm was evaluated under different canopy conditions by comparing its results for canopy openness, fractal dimension and diffuse transmit...

purpose: to present a case of traumatic bilateral eyelid lymphedema. case report: an 18-year old male presented with severe bilateral eye lid lymphedema with a history of severe craniofacial trauma three month ago and neurosurgical procedure. he had lost vision in his left eye because of sever globe injury. his lymphedema was attributed to wide surgical incision scar. the patient underwent manu...

This work presents an evaluation of the word level precision of an automatic segmentation algorithm, NALIGN. Measurements of the portion of temporal overlap between automatic and manual word level segmentations show that a precision of 90 to 95% can be achieved, partly depending on the type of speech material. These precision figures are furthermore only marginally lower than the gold standard ...

in arabic grammar, adjective is one of the five syntactic appositives and thus follows the features and rules of syntactic apposition. usually, there is a main principle on which a consensus of the authentic references is recorded, while the minor rules and secondary regulations might vary in different grammar books. this paper aims at representing ibn ya’ish ‘s viewpoints on adjective and subs...

An automated method for esterifying fatty acids in canola oil samples is presented. Using the Agilent 7696A Sample Prep WorkBench, a side-by-side comparison was undertaken comparing a manual method employing automatic pipettors to a method developed for this automated system. Using the Agilent 7696A Sample Prep WorkBench, preparation of 10 samples resulted in 3% RSD for both an acid-catalyzed a...
