    The Evolution of the Fraction of Individual Phases During a Simultaneous Multiphase Transformation from Time–Temperature Data 

    نوع: Journal Paper
    نویسنده : عطاءاله کامیابی گل; Patricio Fernando Mendez; Ata Kamyabi-Gol
    سال: 2015
    خلاصه:

    A formal mathematical approach to cooling curve analysis of multiple simultaneous transformations is introduced for the first time. The goal of this methodology is to measure individual phase fractions during free cooling. Transformation start...

    Cooling Curve Analysis as an Alternative to Dilatometry in Continuous Cooling Transformations 

    نوع: Journal Paper
    نویسنده : John W. Gibbs; Christian Schlacher; عطاءاله کامیابی گل; Peter Mayr; Patricio F. Mendez; Ata Kamyabi-Gol
    سال: 2015
    خلاصه:

    Dilatometry and cooling curve analysis (CCA) are two methods of determining the evolution of a phase transformation with temperature. The two methods are similar conceptual in that they take an indirect measure of the transformation and extract...

    Breakdown of Simultaneous Phase Transformations by Extending Cooling Curve Analysis 

    نوع: Conference Paper
    نویسنده : عطاءاله کامیابی گل; Patricio F. Mendez; Ata Kamyabi-Gol
    سال: 2014
    خلاصه:

    . Ongoing research on phase transformations has enabled the use of precise temperature measurements during cooling to estimate the evolution of a newly formed phase with time/temperature. This method can go beyond any previous cooling curve analysis approach...

    Robust PSD determination of micro and meso-pore adsorbents via novel modified U curve method 

    نوع: Journal Paper
    نویسنده : M. Niknam Shahrak; اکبر شاهسوند; احمد اخوت; Akbar Shahsavand; Ahmad Okhovat
    سال: 2013
    خلاصه:

    regularization technique. Automatic selection of the optimal regularization level is crucial for efficient extraction of PSD from experimental adsorption or condensation isotherms. A detailed comparison of Leave One Out Cross Validation, L-curve, U-curve...

    Real-time P-H curve CNC interpolators for high speed cornering 

    نوع: Journal Paper
    نویسنده : جواد جهان پور; بهنام معتکف ایمانی; javad jahanpour; Behnam Moetakef Imani
    سال: 2008
    خلاصه:

    Abstract In this paper, real-time Pythagorean hodograph

    (P-H) curve CNC interpolators are used for high speed

    corner machining. There are large contouring errors around

    sharp corners when low-bandwidth servo controllers (such...

    High-speed contouring enhanced with P-H curves 

    نوع: Journal Paper
    نویسنده : بهنام معتکف ایمانی; جواد جهان پور; Behnam Moetakef Imani; javad jahanpour
    سال: 2008
    خلاصه:

    Abstract In this paper, Pythagorean hodograph (P-H)

    curve theory is used for high-speed contouring applications.

    There are large contouring errors around sharp corners

    when low-bandwidth servo controllers (such as P...

    LOOK-AHEAD NURBS-PH INTERPOLATION FOR HIGH SPEED CNC MACHINING 

    نوع: Conference Paper
    نویسنده : بهنام معتکف ایمانی; امیرمحمد قندهاریون; Behnam Moetakef Imani; Amirmohammad Ghandehariun
    سال: 2010
    خلاصه:

    Various methods for parametric interpolation of NURBS

    curves have been proposed in the past. However, the errors

    caused by the approximate nature of the NURBS interpolator

    were rarely taken into account. This paper proposes an...

    Simulation of droplet impact on a curved solid surface by Lattice Boltzmann Method 

    نوع: Conference Paper
    نویسنده : سروش فلاح خارمیانی; محمد پسندیده فرد; soroush fallah kharmiani; Mohammad Passandideh-Fard
    سال: 2017
    خلاصه:

    In this paper, a two-phase multi-relaxation time lattice

    Boltzmann model is implemented to investigate droplet

    impact on a curved solid surface. The improved model is

    capable of simulating...
