sarcheshmeh copper mine, with the final reserves of 828 million tons of sulfur ore and average grade of 0.74%, is known to be the largest open pit of iran and most probably the second largest copper mine in the world. this mine is located in the seismotectonic zone of central-iran, and 23 km away from the 150 km long rafsanjan active fault.in this study the vulnerability of the west wall of the...

Arias is a system serviceee for distributed information systems , which provides low-level support for applications that make an intensive use of sharing and persistence. Arias is based on a persistent distributed shared memory that can be tailored and tuned according to the needs of the supported environment. This paper summarizes the basic design choices and describes the implementation of th...

In this paper, a system for automated analysis of retinal images is proposed. This system segments blood vessels in retinal images and recognizes the main features of the fundus on digital color images. The recognized features were defined as blood vessels, optic disc, and fovea. An algorithm called 2D matched filters response has been proposed for the detection of blood vessels. Also, automati...

BACKGROUND The Arias-Stella reaction is a hormone-related atypical endometrial change characterized by hypertrophy and vacuolization of glandular epithelial cells, associated with marked nuclear pleomorphism, enlargement, and hyperchromasia. When presenting in extra-uterine sites, the differentiation of Arias-Stella changes from other more ominous clear cell lesions may pose significant difficu...

Cumulative absolute velocity (CAV), Arias intensity (AI), and characteristic intensity (CI) are measurable characteristics to show collapse potential of structures, evaluation of earth movement magnitude, and detection of structural failure in an earthquake. In this paper, parameters which describe three characteristics of ground motion have been investigated by using wavelet transforms (WT). I...
