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...

the rapid melting of a semi- infinite body due to the absorption of a cw laser beam radiation has been studied. the enthalpy technique for the solution of phase change problems has been used in an explicit finite difference form to calculate the transient temperature distribution in the semi-infinite body and the growth rate of the melt pool. the technique has been modified so that it is not ne...
