The charge-coupled device (CCD) has been developed primarily as a compact image sensor for consumer and industrial markets, but is now also the preeminent visible and ultraviolet wavelength image sensor in many fields of scientific research including space-science and both Earth and planetary remote sensing. Today’s scientific or science-grade CCD will strive to maximise pixel count, focal plan...

in this article a comparative study for modeling and optimization of 2-methylpropane-2-thiol removal from contaminated soil by ultrasound is investigated. central composite design (ccd) and artificial neural network (ann) were utilized and compared to each other in order to obtain appropriate predicting model with respect to sonication power (w), sonication time (min) and water/reactor volume r...

The task of fitting parametric curve models to boundaries of perceptually meaningful image regions is a key problem in computer vision with numerous applications, such as image segmentation, pose estimation, 3-D reconstruction, and object tracking. In this thesis, we propose the Contracting Curve Density (CCD) algorithm and the CCD tracker as solutions to this problem. The CCD algorithm solves ...

Background: Cleidocranial dysplasia (CCD) is a rare inherited skeletal dysplasia, with an incidence of 1 case per 1000,000 individuals. It is a form of predominantly autosomal dominant inheritance and is associated with a mutation in runt related transcription factor-2 gene mapped on chromosome 6p21. This disease primarily affects the bones formed by intramembranous ossification and is characte...

Measurements were made of the femoral shaft/neck angle (CCD angle) in 106 human foetuses, aged from 16 to 38 hbd, using a "FEM-GEO_03" computer program. The values of the CCD angle in the group under examination were: mean = 140.48 degrees, SD = 6.95 degrees, max = 157.90 degrees, min = 113.93 degrees. No significant differences were found in CCD angle size between male and female foetuses or b...

Based on the principle of CCD vertical target measurement system, this article researched the factors of the CCD camera that affects the target detection performance , including CCD sensitivity and exposure, background illumination and target illumination, CCD distinguish ability, contrast between background and objectives and gave the relevant calculation methods. Through theoretical analysis,...
