background: polymer gel dosimetry is still the only dosimetry method for direct measuring of threedimensional dose distributions. mri polymer gel dosimeters are tissue equivalent and can act as a phantom material. in this study the obtained isodose maps with pagat polymer gel dosimeter were compared to those calculated with egsnrs for singleshot irradiations of 8 and 18 mm collimators of gamma ...

To date, elliptical gear has been commonly used in automobile, automatic machinery, pumps, flow meters and printing presses for its particular non-uniform rotation. However, the dynamic characteristics of elliptical gears have not been clarified yet. In this study, The calculation as well as the experiment of two elliptical gears, which are a single elliptical gear and a double elliptical gear,...

In this paper, the effect of elliptical shape openings was numerically compared to the case when circular openings were used in the steel panel shear walls. At first, the finite element model in ABAQUS was calibrated by experimental results, obtained from previous studies. Then, three steel shear panels with different sizes of elliptical openings were analyzed under cyclic loads, and the result...

removal and hiding a part of the speech indicate to the brevity. not mentioning to the part of the sentence, which in some cases can be considered one of the sentence elements, is one of the most important topics that frequently seen in the quran. one of the omissions in the quran is elliptical answer of condition (shart). identifying the elliptical answer of condition in quran and guessing it,...

Abstract This paper deals with the analysis of fluid flow around bluff bodies using computational dynamics. Two-dimensional rectangular body, semi-circular tip, triangular tip and elliptical nose cone shapes have been considered in paper. The are analysed at various Mach numbers, ranging from 1.5 to 10. aerodynamic characteristics like Drag coefficient drag force investigated. Also, formation s...
