Historically significant documents are often discovered with defects that make them difficult to read and analyze. This fact is particularly troublesome if the defects prevent software from performing an automated analysis. Image enhancement methods are used to remove or minimize document defects, improve software performance, and generally make images more legible. We describe an automated, im...

conclusions compared to iohexol and iopamidol, iodixanol use was associated with a lower patient perception of heat and lower hr while maintaining similar contrast-to-noise and signal-to-noise ratios. results baseline hr was similar across the patients assigned to iohexol, iopamidol, and iodixanol (65.3 ± 9.7, 66.9 ± 10.9, and 65.3 ± 13.3, respectively; p = ns). compared to iohexol and iopamido...

In television and movie industry a so-called "blue box" technology is used, when an object in the foreground (e. g. a person) needs to be placed on a different background (e. g. a computer-generated 3D scene). However, it is often not economically justifiable to build a "blue box", therefore other methods can be used to extract the foreground object and remove or replace bac...

Background The coronary arteries are embedded in epicardial fat. To improve visualization in coronary MR angiography (CMRA) fat suppression techniques such as Spectral Presaturation with Inversion Recovery (SPIR) are often employed. Recently, water-fat separation using the multiecho 2 point Dixon method has gained increasing interest as it allows decomposing the MR signal into a water and fat i...

The Frege-Russell view is that existence is a second-order property rather than a property of individuals. One of the most compelling arguments for this view is based on the premise that there is an especially close connection between existence and number. The most promising version of this argument is by C.J.F. Williams (1981, 1992). In what follows, I argue that this argument fails. I then de...

Surface samples have been collected from Kerala coast, Valapatanam-Azhikode deposit of northern Kerala coast. The average heavy minerals percentage shows 30.32 %. The heavy mineral assemblage of samples from area showed an appreciable percentage of opaque followed by sillimanite and zircon. The chemical analysis carried out for the present investigation, is detailed as Ferrian ilmenite. X-ray d...

A recent physiological finding of neural coding for border ownership (BO) that defines the direction of a figure with respect to the border has provided a possible basis for figure-ground segregation. To explore the underlying neural mechanisms of BO, we investigated stimulus configurations that activate BO circuitry through psychophysical investigation of the BO-dependent tilt aftereffect (BO-...

The time is generally a challenging task. All issues in relation to time can be better supported using temporal data models. Almost all enterprise database systems have implemented temporal data, partly according to the model specified in the SQL:2011 standard and partly according to other, older temporal models. In this article five temporal concepts will be used to investigate their implement...

Most ovarian masses are benign conditions such as non neaplastic cystic, but on the other hand , ovarian cancer, is the third most common gynecological malignancy which has the highest mortality rate , as a result of late diagnosis. As there are few clinical symptoms, most patients at the Abstracts of the 12th Royan International Congress on Reproductive Biomedicine 2 3 International Journal of...
