Radial or pincushion distortion problem of the wide angle charge-coupled device (CCD) camera is an important issue in the image calibration in case of close-up photography of real scene. We designed the auto-extraction method of the warping points in the calibration algorithm of the image acquired by the wide angle CCD camera. Proposed method extracts the distortion point by the wide angle CCD ...

background and objectives: discharge of wastewater from textile dyeing industries has been a problem in terms of pollution and treatment of these waters is a great task. keeping this in mind, the aim of our current research is to study the effect of various bioprocess variables on decolorization of an azo dye, congo red, by a fungal isolate, aspergillus niger hm11. materials and methods: centra...

During the maintenance period of a future fusion reactor power plant, called DEMOnstration Power Plant (DEMO), remotely handled casks are required to confine and handle DEMO in-vessel components during their transportation between active facility. In order limit dispersion activated dust, Contamination Control Door (CCD) is designed be placed at an interface separable containments (e.g., vacuum...

Previous studies have shown that air pollutants a significant impact on cardiovascular and cerebrovascular diseases (CCD), but these focused more provincial capitals or large cities. This study was the first time to explore effects of CCD in Luoyang. In this study, generalized additive model (GAM) used establish single-pollutant model, multi-pollutant stratified modes age, sex season evaluate P...

Charged-coupled device (CCD) detectors have been widely accepted as detectors for collecting X-ray diffraction images. The CCD detector offers a sensitive detection system well suited for diffraction analysis and, compared with other detectors on the market, a relatively rapid system for read-out of the collected image. The two predominant markets for the CCD detector have been those in which r...

The results of on-orbit measurements of the STIS/CCD imaging throughputs are reported. Wavelength-dependent aperture corrections and revisions to detector and filter throughput curves are presented. The throughput of the F28X50LP filter is found to be close to prelaunch estimates. Initial on-orbit measurements of this filter had suggested a 28% lower throughput, but we find instead that the ove...

BACKGROUND Allergy diagnosis by determination of allergen-specific IgE is complicated by clinically irrelevant IgE, of which the most prominent example is IgE against cross-reactive carbohydrate determinants (CCDs) that occur on allergens from plants and insects. Therefore, CCDs cause numerous false-positive results. Inhibition of CCDs has been proposed as a remedy, but has not yet found its wa...

Quantitative crossed cerebellar diaschisis (CCD) and the correlation with a reduction in supratentorial regional cerebral blood flow (rCBF) and cerebrovascular reserve capacity (CVR) were investigated in clinically stable patients with major cerebral artery occlusion by the iodine-123-N-isopropyl-p-iodoamphetamine (I-123 IMP) single photon emission computed tomography (SPECT) method. Thirty pat...
