A computational fluid dynamic (CFD) study compared two configurations of distal anastomosis of 12 mm Contegra conduit: conventional 'circular' vs. oblique 'elliptical' anastomosis extended on the left PA, evaluating pressure and velocity profiles, and shear stress, from PA origin to the bifurcation. 'Elliptical' anastomosis provides larger (=54% difference) cross-sectional area than 'circular' ...

A novel flexure hinge named half circular-elliptical hybrid flexure hinge was presented. Based on Castigliano’s Displacement Theorem, the compliance equations of the novel flexure hinge were formulated. A computer aided analysis and parametric design program of the half circular-elliptical hybrid flexure hinge was developed by VC++6.0. A specific half circular-elliptical hybrid flexure hinge wa...

30 ‘circular’ vs. oblique ‘elliptical’ anastomosis extended on the left PA, evaluating pressure and velocity profiles, and shear stress, from PA 31 origin to the bifurcation. ‘Elliptical’ anastomosis provides larger (s54% difference) cross-sectional area than ‘circular’ anastomosis. Velocity 32 contours showed important stagnation at PA bifurcation in ‘circular’ anastomosis and minimal in ‘elli...

Using complex variable methods and conformal mapping techniques, we establish the existence of coated cavities of various shapes that do not disturb the warping function in a host elliptical bar. These cavities are known as ‘partly neutral cavities’. Our results show that the two axes corresponding to the neutral elliptical coating are parallel to those of the host elliptical bar and that the c...

In this paper we present a new type of multivariate distributions for asset returns which we call the multi-tail elliptical distributions. Multi-tail elliptical distribution can be thought to be an extension of the elliptical distributions that allow for varying tail parameters. We present a two-step random mechanism leading to this new type of distributions. In particular, this mechanism is de...

Eksilti, yazılı ve sözlü anlatımda bazı dil birimlerini, yine o dilin kuralları çerçevesinde derin yapıda bırakan bir olayıdır. Yazarken veya konuşurken konuşmaya canlılık katmak, akıcılık sağlamak, tekrardan kaçınmak, tasarruf etmek, vurgu yapmak vb. gibi nedenlerden dolayı dilde çeşitli eksiltiler yapılır. Hafz, eksiltim, eksilti, eksiltili anlatım, düşüm, düşürme, kısaltma, sıfır tekrar, eli...

This article reviews the popular reasons for the belief that dwarf elliptical galaxies and (ordinary) elliptical galaxies are distinct and separate species. They include: light–profile shape (or similarly image concentration); the magnitude–central surface brightness diagram; the magnitude–effective surface brightness diagram (or similarly the magnitude–effective radius diagram); and the Fundam...

This letter presents a miniaturized probe-fed elliptical microstrip patch antenna (PF-EMPA) targeting the 8.50-10.55 GHz band for radiolocation applications. The proposed design is composed of an elliptical patch inserted into an elliptical slot. In order to achieve our goals and control the impedance matching, we adjusted the offset distance from the elliptical patch to the side of the ellipti...
