Texture is generally recognized as fundamental to perceptions. There no precise definition or characterization available in practice. recognition has many applications areas such medical image analysis, remote sensing, and robotic vision. Various approaches statistical, structural, spectral have been suggested the literature. In this paper we propose a method for texture feature extraction. We ...

Beams of microscopic particles penetrating scattering background matter play an important role in several applications. The parameter choices made here are motivated by the problem of electron-beam cancer therapy planning. Mathematically, a steady particle beam penetrating matter, or a configuration of several such beams, is modeled by a boundary value problem for a Boltzmann equation. Grid-bas...

this work presents thermoplastic analysis of fg rotating diskswith variable thickness and constant angular velocity. the solutions are obtained by variable material property (vmp) theory. in this theory, the domain is divided into some finite sub-domains in the radial direction, in which the properties are assumed to be constant and the form of the elastic response is used to solve elastic-plas...

BACKGROUND In the 1920s and 1930s, disability glare was a topic of great interest in the Commission Internationale de l'Eclairage (CIE). The Second World War prevented agreement being reached on a standard to quantify disability glare but the Stiles-Holladay formula was widely accepted as such. In 1983, CIE started a new effort to develop a CIE standard making use of research data published in ...

چکیده ارتباط بین عوامل محیطی با گونه های گیاهی همیشه یک موضوع اصلی در اکولوژی گیاهی بوده است. تعیین این روابط کمی هسته اصلی مدلسازی پیش بینی پراکنش مکانی بالقوه گونه های گیاهی به شمار می رود. این مدل ها به منظور کسب اطلاعات درباره پراکنش مکانی گونه ها، شناسایی زیستگاههای مناسب و ارزیابی آثار تغییر اقلیم در پراکنش مکانی گونه ها به کار گرفته می شوند. از اهداف این مطالعه، شناسایی عوامل محیطی موثر...
