The present study investigated the effect of updated localized material s on the English language achievement of undergraduate students of Political Science in their English for sp ecific purposes (ESP) courses in Iran. Sixty - five male and female undergraduate students (19 - 26 years old) from two universities in Iran participate d in this study. They were divided into two intact classes cons...

In this paper, following a two-stage methodology, the differential quadrature element (DQE) model of a three-story frame structure is updated for the vibration analysis. In the first stage, the mass and stiffness matrices are updated using the experimental natural frequencies. Then, having the updated mass and stiffness matrices, the structural damping matrix is updated to minimize the error be...

The purpose of this research has been to present the importance of combining topographical, morphological and etiological information of diagnostic evaluation on grading gastritis in our material according to th...

Dynamic Programming by Dimitri P. Bertsekas Massachusetts Institute of Technology Chapter 4 Noncontractive Models UPDATED July 17, 2017 This is an updated version of Chapter 4 of the author’s research monograph “Abstract Dynamic Programming,” Athena Scientific, 2013. It replaces Sections 4.4-4.7 of the original with new material. The chapter will be periodically updated, and represents “work in...

Purpose – The purpose of this paper is to develop a heuristic method for topology optimization of a continuum with bi-modulus material which is frequently occurred in practical engineering. Design/methodology/approach – The essentials of this model are as follows: First, the original bi-modulus is replaced with two isotropic materials to simplify structural analysis. Second, the stress filed is...

To increase the production efficiency of a typical turbine blade, it is necessary to change its material and hence its production technology. In this respect and in order to make sure that newmat...

the subfamily alysiinae (hymenoptera, braconidae) is one of the most peculiar and diverse endoparasitoids of the family braconidae. a sampling survey was done in different parts of iran, mainly in south, central and south eastern provinces. fifteen species are recorded for the first time from iran. they were belonging to tribe alysiini (dinotrema amparoae peris-felipo, 2013; d. borzhomii tobias...

Preliminary notes based on course material from Professor Boneh’s Topics in Cryptography course (CS 355) in Spring, 2014. There are probably typos. Last updated: June 19, 2014

The objective of the present work is to develop finite element based optimization techniques for laminated composite shell structures. The platform of implementation is the finite element based analysis and design tool MUST (MUltidisciplinary Synthesis Tool) and a number of features have been added and updated. This includes an updated implementation of finite elements for shell analysis, tools...
