نگهداری از زیرساخت ها به همان اندازه ی ایجاد و توسعه زیرساخت ها امری ضروری برای توسعه پایدار می باشد. شبکه راه ها یکی از اساسی ترین ارکان توسعه پایدار محسوب می شوند. برای نگهداری از شبکه راه ها وجود یک سامانه مدیریت نگهداری روسازی الزامی است که بتوان از آن به عنوان ابزار تصمیم گیری استفاده کرد. به همین دلیل اکثر کشورهای در حال توسعه به دنبال یک سامانه مدیریت نگهداری روسازی کارآمد هستند که بتوان...

Adding textures to surfaces is known improve the external appearance of injection moulded components. However, when high surface quality required, normally a paint coating applied on top textured surface. In this work, an alternative painting for obtaining proposed, following environmental-friendly process and having low production cost. Three different obtained by moulding have been characteri...

Abstract The research on surface texture is developing from single macro-texture to composite micro-nano texture. current the anti-friction mechanism and theoretical models of textures relatively weak. Studying characteristics different types determining applicable working conditions each focus research. In this paper, a mathematical model hydrodynamic lubrication established based Navier–Stoke...

Breast cancer is the second commonest type of cancer in the world, and the commonest among women, corresponding to 22% of the new cases every year. This work presents a new computational methodology, which helps the specialists in the detection of breast masses based on the breast density. The proposed methodology is divided into stages with the objective of overcoming several difficulties asso...

With the advent of image based modeling techniques, it becomes easier to apply textures extracted from reality onto virtual worlds. Many repetitive patterns (structural textures) in human constructions can be parametrized with procedural textures. These textures offer a powerful alternative to traditional color textures, but they require the artist to program the desired effects. We present a s...

Placing micro-textures on a tool surface can play an anti-wear and friction-reducing role capture impurities improve the tool-chip friction state, thus improving cutting performance of quality workpiece. To ensure processing in micro-texture-coated tool-cutting process, process parameters micro-texture are limited to smaller parameters, which reduces efficiency increases cost. Aiming at this pr...

The study area is located in the Varzeghan city and in the province of the East Azerbaijan. Mineralization in the Hizeh –Jan area is ​​gold mineralization type and associated with quartz and quartz - carbonate veins and veinlets, which is occurred in the Eocene volcanic rocks with andesite composition. The most significant alteration in this area, is developing of propylitic, argillic and silic...

Arousan -e- Kaboudan area, located about 115 km northeast of Nain (south of Choupanan), is part of Central Iran (Yazad block). The Eocene volcanic rocks of the area are composed of lavas and pyroclastic rocks. The lavas can be divided into acidic (rhyodacite) and relatively basic-basic (trachyandesite, mugearite and hawaiite) rocks. The textures of these rocks are trachytic, hyaloporphyritic an...
