1. Experimental and Numerical Investigation of Groove Pressed UFG Pure Aluminum

akbar sajadi; F. Javanroodi; M. Borhani

Volume 5, Issue 2 , March 2012

Abstract
  Fabrication of ultrafine grained materials by imposing severe plastic deformation for improvement of mechanical and physical properties of metals has been the focus of many researches over the past few years. In this process, a sheet is subjected to repetitive shear deformation conditions by utilizing ...  Read More

2. Proportional-derivative Fuzzy Control of Conjugated Polymer Actuators

A. Amirimighadam; M. Maarefdoust

Volume 5, Issue 2 , March 2012

Abstract
  Conjugated polymer actuators can be employed to achieve micro and nano scale precision, and have a wide range of applications including biomimetic robots, and biomedical devices. In comparison to robotic joints, they do not have friction or backlash, but on the other hand, they have complicated electro-chemo-mechanical ...  Read More

3. Experimental investigation and mathematical modeling of the composite ceramic cutting tools with alumina base in the machining process of PH-hardened Austenitic-ferritic (Duplex) stainless steel

Ehsan Ahmadi; Rasool Mokhtari Homami; Sadegh Rahmati

Volume 5, Issue 2 , March 2012

Abstract
  Abstract: The lifetime of a cutting tool is an important and determinant parameter for evaluating its performance. The amount of tool abrasion affects seriously dimensions and surface quality of the working piece so that one of the main factors to determine the lifetime of a tool is the level of its ...  Read More

4. Evaluation of the using Al2O3/EG and TiO2/EG nanofluids as coolants in the double-tube heat exchanger

Navid Bozorgan

Volume 5, Issue 2 , March 2012

Abstract
  Abstract: In this study, Al2O3/EG and TiO2/EG nanofluids as coolants have been used in the double-tube heat exchanger. The hot solvent inlet heat exchanger must be cooled down with a specified amount. We can use nanofluids as coolants in the heat exchanger for optimization of the heat transfer area. ...  Read More

5. Presenting a New Method for High Speed Incremental Forming

M. Vahdati; A.R. Vahdati

Volume 5, Issue 2 , March 2012

Abstract
  Recently, incremental sheet metal forming (ISMF) process as one of the new methods in rapid prototyping collection has been considered by researchers. This process is based on a defined path in CNC controller and applies a spherical-head tool that supplies the required pressure for sheet metal forming. ...  Read More

6. A semi-analytical solution for time-variant thermoelastic creep analysis of functionally graded rotating disks with variable thickness and properties.

Mohammad Taghi Ghorbani

Volume 5, Issue 2 , March 2012

Abstract
  Abstract: A time domain semi-analytical solution to study thermoelastic creep behavior of  functionally graded rotating axisymmetric disks with variable thickness is presented. The rate type governing differential equations for the considered structure are derived and analytically solved. To solve ...  Read More

7. Using the Bees Algorithm with the Boundary Elements Method to Solve the Inverse Problem of Transient Heat Conduction

Mohsen Dashti Ardakani; Seyd Mohammad Mehdi MizanAdl

Volume 5, Issue 2 , March 2012

Abstract
  Abstract: In this paper, a new population-based search called the Bees Algorithm (BA) is presented to estimate the time-dependent heat transfer coefficient and the corresponding heat flux at the boundaries of a two-dimensional body subjected to transient heat conduction, using the temperature measurements ...  Read More

8. Free Chattering Fuzzy Sliding Mode Controllers to Robotic Tracking Problem

reza azarafza; SAEED MOHAMMAD Hoseni; MOHAMMAD FARROKHI

Volume 5, Issue 2 , March 2012

Abstract
  Sliding mode control (SMC) is a powerful approach to solve the tracking problem for   dynamical systems with uncertainties. However, the traditional SMCs introduce actuator chattering phenomenon which performs a desirable behavior in many physical systems such as servo control and robotic systems, ...  Read More

9. Numerical Simulation of 2-D Incompressible Flow in Micro Semi-circular Cavity by LBM

Mina Alafzadeh; Shahram Talebi

Volume 5, Issue 2 , March 2012

Abstract
  Abstract: Since the field of micro electromechanical systems (MEMS) continues to grow, the flow in micro devices have become an area that receives a significant attention. The microscopic flows are usually characterized by the Knudsen number (Kn). When the characteristic size of the particle decreases ...  Read More
