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 ... -
Which replacement is better before or after a specified time for minimal repair models
( International Society of Science and Applied Technologies , 2016 , Conference Paper)This paper compares the models of replacement first, replacement interval, replacement last and replacement overtime to decide which policy would be better before or after a specified time T in the viewpoint of cost saving. ... -
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) ... -
Wireless active noise control results
( International Institute of Acoustics and Vibrations , 2016 , Conference Paper)Active Noise Control (ANC) is used in controlling low frequency noise where passive control is ineffective. Most (ANC) systems use physical cables to connect various parts of the system for operation. This can be bulky and ... -
