tiles and tilework has developed in islamic civilization based on pre-islamic iranian art and then spread out from spain to central asia. herein, iran has played an individual role among different islamic countries and remnants of various tileworks across this wide territory are clear evidences to this claim. among different species of tiles and tile decorations, we face with specific types of ...

This thesis project proposes a software solution that provides an interface more akin to traditional artistry. With the system proposed, a user will be able draw a simple two-dimensional sketch of a figure or object and convert it into a 3D object without having to rebuild the figure from scratch in a 3D development environment. Because such sketches are crude in nature, the newly created figur...

LIGHTWEIGHT CONCRETE May consist of lightweight aggregates are used in ordinary concrete of coarse aggregate and sand, clay, foamed slag, clinker, crushed stone, aggregates of organic and inorganic. It used in different common shapes such as light weight aggregate concrete [1], concrete without fine [2] or concrete with bubble [3]. It is replaced by normal concrete in several applications becau...

1. This study investigated how the size of crevices might affect their effectiveness as refuges for diatom-dominated algal assemblages from the grazing minnow Campostoma anomalum. 2. Crevice size was manipulated by making fired-clay substrates, using moulds to produce eight substrates with pits from 1.17 to 22.0 mm diameter. Non-pitted clay-stones and limestone were also tested. Cages were used...

In this paper, the particle shape factor of stone in soil-rock mixture was used as specific research object geogrid pull-out test, combining random generation method and evaluation criteria rock blocks mixture, a feasible for classifying stones according to their factors is presented. By comparing mechanical behavior composed with different material tests under working conditions, we studied it...
