Computing trade-offs in robust design: Perspectives of the mean squared error
(Pergamon-Elsevier Science Ltd, 2011)
Researchers often identify robust design as one of the most effective engineering design methods for continuous quality improvement. When more than one quality characteristic is considered an important question is how to ...
Master problem approximations in Dantzig-Wolfe decomposition of variational inequality problems with applications to two energy market models
(Pergamon-Elsevier Science Ltd, 2013)
In this paper a modification to Dantzig-Wolfe (DW) decomposition algorithm for variational inequality (VI) problems is considered to alleviate the computational burden and to facilitate model management and maintenance. ...
'Level grading' a new graded algebra structure on differential polynomials: application to the classification of scalar evolution equations
(IOP Publishing Ltd, 2013)
We define a new grading which we call the 'level grading' on the algebra of polynomials generated by the derivatives u(k+i) over the ring K-(k) of C-infinity functions of x t u u(1) ... u(k) where . This grading has the ...
Flow and Turbulence Structure Around an In-Stream Rectangular Cylinder with Scour Hole
(TSINGHUA UNIV, 2013)
An eddy resolving technique is used to reveal the unsteady dynamics of the coherent structures present in the flow field around an in-stream vertical cylinder with a scour hole at a channel Reynolds number of 240000. Such ...
Evaluating machine tool alternatives through modified TOPSIS and alpha-cut based fuzzy ANP
(Elsevier Science Bv, 2012)
The problem of machine tool selection among available alternatives has been critical issue for most companies in fast-growing markets for a long time. In the presence of many alternatives and selection criteria the problem ...
An interactive memetic algorithm for production and manufacturing problems modelled as a multi-objective travelling salesman problem
(Taylor & Francis Ltd, 2012)
In this paper a preference-based interactive memetic random-key genetic algorithm (PIMRKGA) is developed and used to find (weakly) Pareto optimal solutions to manufacturing and production problems that can be modelled as ...
Models for relief routing: equity efficiency and efficacy
(Pergamon-Elsevier Science Ltd, 2012)
In humanitarian relief operations vehicle routing and supply allocation decisions are critically important. Similar routing and allocation decisions are studied for commercial settings where efficiency in terms of minimizing ...
Canonical forms for families of anti-commuting diagonalizable linear operators
(Elsevier Science Inc, 2012)
It is well known that a commuting family of diagonalizable linear operators on a finite dimensional vector space is simultaneously diagonalizable. In this paper we consider a family A = {A(a)} A(a) : V -> V a = 1... N of ...
A framework for water and carbon footprint analysis of national electricity production scenarios
(Pergamon-Elsevier Science Ltd, 2017)
While carbon footprint reduction potential and energy security aspects of renewable and non-renewable resources are widely considered in energy policy their effects on water resources are mostly overlooked. This research ...
Chelate extraction of transition metal ions by ethylene diamine diacetic acid with n-substituted octadecyl groups
(Taylor & Francis Inc, 2002)
An organic-soluble chelating agent NN'-di-n-octadecyl ethylenediamine-NN'-diacetic acid (DOED) has been synthesized in two steps by (i) condensation of dibromoethane with 1-amino octadecane (octadecylamine) and (ii) ...
