purpose: to assess orbital color doppler ultrasonography (cdu) parameters of patients with manifest hyperopia in comparison to the emmetropes methods: forty eyes of 40 patients presenting with manifest hyperopia were included into the study. forty eyes of 40 emmetropes healthy volunteers also were examined as the control group. we have evaluated ophthalmic artery (oa), central retinal artery (c...

conclusions our study showed that ultrasonography findings can be a good predictor of sperm parameters in patients with varicocele. results the semen analysis parameters, including semen volume and sperm morphology, count, and motility, significant correlations with the diameter of the varicocele vein but were not correlated with testes size. in addition, the patients with reflux of longer than...

Received: 27 April 2013 Accepted: 6 August 2013 Abstract Background and Aim: Discoloration is among the most common problems of composite restorations. Color change over time compromises the main advantage of composite resins namely their high esthetics. In such cases, the restoration needs to be replaced. .The aim of this in-vitro study was to evaluate the effect of accelerated artificial agin...

Color space conversion has become a very important role in the image acquisition, display and the transmission of the color information in the replication. Printers and Image setter express color by CMYK space. But if color is edited and corrected in the CMYK space, it will cause a greater loss of color, and the Computing of computer will also be slowed down. So it often needs to be converted t...

Color processing methods can be divided into methods based on human color vision and spectral based methods. Human vision based methods usually describe color with three parameters which are easy to interpret since they model familiar color perception processes. They share however the limitations of human color vision such as metamerism. Spectral based methods describe colors by their underlyin...

The Lentinula edodes stipe (LES), a by-product of L. fruiting body processing, is rich in dietary fiber, protein, and polysaccharides, which can be served as the functional ingredient dairy products. In this study, stirred yogurts fortified with 1%, 2%, 3% LES were prepared, effects on changes color, pH, titratable acidity (TA), viable lactic acid bacteria (LAB) cells, syneresis, viscosity, tex...

Creative tools are proposed that allow color stylists to take advantage of their training in the art and design fields. A simple reflection model is employed that has the minimum number of free parameters required to design solid and metallic color finishes from conceptualization to fabrication. The parameters correspond to color specification terms familiar to designers such as face color, flo...

In order to identify maize purity rapidly and efficiently, the image processing technology and clustering algorithm were studied and explored in depth focused on the maize seed and characteristics of the seed images. An improved DBSCAN on the basis of farthest first traversal algorithm (FFT) adapting to maize seeds purity identification was proposed in the paper. The color features parameters o...

In this section we list all the threshold and parameters, and their numerical values, kept constant throughout each experiment. Together with the main body of the paper, this enables independent implementation and reproduction of the results. More importantly, we plan to release our implementation, so independent validation is straightforward. The three key threshold in our algorithm are: εr on...
