an investigation into oral interaction in language classes: a conversation analytic point of view the aim of this thesis is to analyze the interaction between language teachers and students in english language institutes. this work is done in the context of yasuj city. learning another language, which is in most cases english, involves many variables. one of these variables is the linguistic...
in civil engineering concrete is a material combined of hydraulic cement, sand, gravel and water. gravel and sand compose 60 to 70 percent of concrete. these aggregates support compression force of concrete. cement paste acts as glue to stick grain together. in bushehr factories producing aggregates do not operate according to astm standards, so that fineness modulus (fm) of the produced sands ...
The rapid development of computers and the internet has given new opportunities for engineering work as wells as for teaching and learning. The use of advanced modern mathematics is becoming increasingly more popular in the engineering community and and most problem solutions and developments incorporate high precision digital models, numerical analyses and simulations. However, this kind of ma...

Abstract Problems of the branch mathematics called differential games, which today find their versatile applications in physics and engineering, are devoted to construction chase control when states object known only at given times advance. Sufficient conditions for possibility completing pursuit sense hitting a small neighborhood terminal set obtained. A method is indicated constructing positi...
Today, in the industry 4.0 era, boundaries of scientific disciplines are blurred, everything seems to be interrelated and shows ability combined. Intelligent sensors combined with Artificial Intelligence (AI) have demonstrated their influence processes, design, maintenance manufacturing systems. Mechanical engineering tasked solving complex problems must able adapt this transformation, especial...
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
