Tuning the electrical properties of polyaniline by copolymerization with o-bromoaniline
(
World Scientific Publishing Co. Pte Ltd
, 2017 , Article)
Polyaniline, poly(o-bromoaniline) and poly(aniline-co-o-bromoaniline)s have been prepared by chemical oxidative polymerization methods. A series of poly(aniline-co-o-bromoaniline) derivatives has been prepared by the ...
Linear stability analysis of finite length journal bearings in laminar and turbulent regimes
(
SAGE Publications Ltd
, 2017 , Article)
Dynamic coefficients of a finite length journal bearing are numerically calculated under laminar and turbulent regimes based on Ng-Pan-Elrod and Constantinescu models. Linear stability charts of a flexible rotor supported ...
Chatter stability prediction for a flexible tool-workpiece system in a turning process
(
Springer London
, 2017 , Article)
The paper focuses on the chatter stability prediction for a flexible tool-workpiece system in a turning process. The dynamic model of the turning process presented here considers two end conditions of the flexible workpiece. ...
The spectral and morphological studies of the conductive polyaniline thin film derivatives by the in situ copolymerization
(
Springer New York LLC
, 2017 , Article)
Thin film of copolymers of poly(aniline-co-2-iodoaniline) are obtained by in situ copolymerization of aniline and 2-iodoaniline as the startup monomers by chemical oxidation upon varying the molar feed to ratio of monomers ...
A fuzzy long-term investment planning model for a GenCo in a hybrid electricity market considering climate change impacts
(
Springer New York LLC
, 2017 , Article)
We study the long-term generation capacity investment problem of an independent power generation company (GenCo) that functions in an environment where GenCos perform business with both bilateral contracts (BC) and ...
White graphene reinforced polypyrrole and poly(vinyl alcohol) blend nanocomposites as chemiresistive sensors for room temperature detection of liquid petroleum gases
(
Springer-Verlag Wien
, 2017 , Article)
The authors describe the preparation of PVA/WPPy/hBNNP nanocomposite films by solution casting method from poly(vinyl alcohol) (PVA), water soluble polypyrrole (WPPy), and using hexagonal boron nitride nanoparticles (hBNNP) ...
Investigation of optimal charging locations for electric vehicles in Istanbul
(
IEOM Society
, 2017 , Conference Paper)
Electric vehicles have a great potential to decrease the adverse effects of transportation, especially in metropolitan cities. On the other hand, adoption of the electric vehicles requires supporting infrastructure such ...
Application of value stream mapping (VSM) for lean and cycle time reduction in complex production environments: a case study
(
Taylor and Francis Ltd.
, 2017 , Article)
The application of VSM is a proven approach for lean-based improvements. Typically, this becomes challenging, when applied for complex production environments. The purpose of this research is to demonstrate, how with some ...
A simulation-optimisation approach for supply chain network design under supply and demand uncertainties
(
Taylor and Francis Ltd.
, 2017 , Article)
We investigate a three-echelon stochastic supply chain network design problem. The problem requires selecting suppliers, determining warehouses locations and sizing, as well as the material flows. The objective is to ...
Monitoring multistage processes with autocorrelated observations
(
Taylor and Francis Ltd.
, 2017 , Article)
In multistage manufacturing processes, autocorrelations within stages over time are prevalent and the classical control charts are often ineffective in monitoring such processes. In this paper, we derive a linear state ...
