A framework for optimizing the supply chain performance of a steel producer
(2013 , Conference Paper)
Supply Chain Management (SCM) is focused on developing, optimizing, and operating efficient supply chains. Efficient supply chains are characterized by cost effective decisions, lean flow and structure, high degree of ...
A new hybrid extragradient iterative method for approximating the common solutions of a system of variational inequalities, a mixed equilibrium problem, and a hierarchical fixed point problem
(
Hindawi
, 2013 , Article)
We suggest and analyze an iterative scheme for finding the approximate element of the common set of solutions of a system of variational inequalities, a mixed equilibrium problem, and a hierarchical fixed point problem in ...
Regression-type estimators for adaptive two-stage sequential sampling
(
Springer
, 2013 , Article)
Adaptive two-stage sequential sampling (ATSSS) design was developed to observe more rare units and gain higher efficiency, in the sense of having a smaller variance estimator, than conventional sampling designs with equal ...
Asymptotic properties of the sample mean in adaptive stratified sequential sampling with multiple selection criteria
(
Iranian Mathematical Society
, 2013 , Article)
We extend the method of adaptive two-stage sequen-tial sampling to include designs where there is more than one crite-ria used in deciding on the allocation of additional sampling effort. These criteria, or conditions, can ...
Aqueous electrolyte system for porous silicon using electrochemical anodization
(
IEEE Xplore
, 2013 , Conference Paper)
Electrochemical anodization on n-type silicon was performed with silicon as anode and platinum as cathode in a weak-acid aqueous electrolyte containing orthophosphoric acid and ammonium fluoride. Anodization was carried ...
Creating textured surfaces using plasma electrolysis
(
Materials Research Society
, 2013 , Article)
Plasma electrolysis (PE) is a combination of electrolysis and plasma discharge. Previous studies indicated that PE usually created porous surface with irregular morphology as a result of the plasma-cathode interaction that ...
Control of parabolic PDEs with time-varying spatial domain: Czochralski crystal growth process
(
Taylor and Francis Ltd.
, 2013 , Article)
This paper considers the optimal control problem for a class of convection-diffusion-reaction systems modelled by partial differential equations (PDEs) defined on time-varying spatial domains. The class of PDEs is characterised ...
Boundary optimal (LQ) control of coupled hyperbolic PDEs and ODEs
(
Elsevier
, 2013 , Article)
This contribution addresses the development of a linear quadratic (LQ) regulator for a set of hyperbolic PDEs coupled with a set of ODEs through the boundary. The approach is based on an infinite-dimensional Hilbert ...
Optimal control of an advection-dominated catalytic fixed-bed reactor with catalyst deactivation
(
Elsevier
, 2013 , Article)
The paper focuses on the linear-quadratic control problem for a time-varying partial differential equation model of a catalytic fixed-bed reactor. The classical Riccati equation approach, for time-varying infinite-dimensional ...
