© 2018, Springer-Verlag GmbH Germany, part of Springer Nature. Abstract: We report the synthesis and luminescence properties of the pure and Al-doped photosensitive ZnO films by microwave successive ionic layer adsorption ...
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) ...
Uniform fractional factorial design tables for energy piles with maximum thermal conductance
(
WITPress
, 2017 , Conference Paper)
Energy Piles are the heat exchangers of Ground Source Heat Pumps (GSHP) that transfer the buildings heat to the lower temperature shallow ground reducing the energy consumption in the cooling of buildings. These piles are ...
First and Last Triggering Event Approaches for Replacement with Minimal Repairs
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Article)
To make effective use of a running system, this paper proposes that, when replacement times could be scheduled at a planned time T of operation, and at a number N of minimal repairs, the newly proposed approach of whichever ...
Energy Absorption Capability of Cotton Fiber/Epoxy Composite Square and Rectangular Tubes
(
Taylor and Francis Inc.
, 2016 , Article)
This paper investigates the energy-absorption capability of natural fiber cotton fabric/epoxy square tubes. The cross-sectional aspect ratio was varied randomly from 0.50 to 2.57. Quasi-static crushing tests in axial and ...
What is Middle Maintenance Policy?
(
John Wiley and Sons Ltd
, 2016 , Article)
The main purpose of this paper is to propose several new maintenance policies that can be performed at suitable middle times for trivariate preventive maintenance scenarios. Firstly, characteristics and limitations for the ...
Impedance spectroscopy, ionic conductivity and dielectric studies of new Li+ ion conducting polymer blend electrolytes based on biodegradable polymers for solid state battery applications
(
Springer New York LLC
, 2016 , Article)
New solid polymer blend electrolyte films based on biodegradable polymer blend comprising of polyvinyl alcohol (PVA) and poly (N-vinyl pyrrolidone) (PVP) doped with different wt% of lithium carbonate (Li2CO3) salt have ...
Influence of changing casing groove parameters on the performance of centrifugal compressors near stall condition
(
American Society of Mechanical Engineers (ASME)
, 2016 , Article)
The casing treatment is an effective method for increasing the stall margin of compressors and enhancing the flow distribution at the blades tip. The present numerical study focuses on making an optimization of the casing ...
Comparisons of standby and parallel systems in reliability, replacement, scheduling and application
(
SAGE Publications Ltd
, 2016 , Article)
This paper compares the standby and parallel systems through the following analyses: reliability measures such as reliabilities, mean times to failure, and failure rates are first compared. These comparisons are reconsidered ...
A PSO approach for robust aircraft routing
(
IEEE Computer Society
, 2016 , Conference Paper)
To mitigate the impact of unpredictable disruptions, airlines are seeking to proactively design schedules that incorporate some robustness features. In this paper, we propose a novel simulation-optimization approach using ...
