A new insight in determining the percolation threshold of electrical conductivity for extrinsically conducting polymer composites through different sigmoidal models
( MDPI AG , 2017 , Article)The electrical conductivity of extrinsically conducting polymer composite systems passes through a transition state known as percolation threshold. A discussion has been made on how different Sigmoidal models (S-models), ... -
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 ... -
Effectiveness of Ni incorporation in iron oxide crystal structure towards thermochemical CO2 splitting reaction
( Elsevier Ltd , 2017 , Article)In this study, Ni-doped iron oxide (NixFe3−xO4) materials were synthesized via the 1,2-epoxypropane assisted sol-gel method by varying the molar concentration of Ni from x=0.2 to 1. Sol-gel derived NixFe3−xO4 gels were ... -
Age replacement models: A summary with new perspectives and methods
( Elsevier Ltd , 2017 , Article Review)Age replacement models are fundamental to maintenance theory. This paper summarizes our new perspectives and hods in age replacement models: First, we optimize the expected cost rate for a required availability level and ... -
Effect of composite intramedullary nails (IM) on healing of long bone fractures by means of reamed and unreamed methods
( Elsevier Ltd , 2017 , Article)Complications are common during bone fracture healing owing to incompatibility of the implants. Flexible fibrous composite materials are promising materials that offer excellent biomechanical compatibility. Flexible composite ... -
Random number of units for K-out-of-n systems
( Elsevier Inc. , 2017 , Article)This paper takes up the reliability and preventive replacement problems for a K-out-of-n system, where K is a stochastic parameter provided. Firstly, we consider the case when K is predefined as constant numbers as is done ... -
Analyzing the Behavior of Classical Functionally Graded Coated Beam
( EDP Sciences , 2017 , Conference Paper)The governing equation of a classical rectangular coated beam made of two homogeneous layers at top ceramic coated layer and bottom metal layer and also single Functionally Graded Material (FGM) as a sub coated layer ... -
The synthesis, characterization and in vivo study of mineral substituted hydroxyapatite for prospective bone tissue rejuvenation applications
( Elsevier Inc. , 2017 , Article)Minerals substituted apatite (M-HA) nanoparticles were prepared by the precipitation of minerals and phosphate reactants in choline chloride-Thiourea (ChCl-TU) deep eutectic solvent (DESs) as a facile and green way approach. ... -
A hybrid optimization-simulation approach for robust weekly aircraft routing and retiming
( Elsevier Ltd , 2017 , Article)We address the robust weekly aircraft routing and retiming problem, which requires determining weekly schedules for a heterogeneous fleet that maximizes the aircraft on-time performance, minimizes the total delay, and ... -
A Fast Responsive Ultraviolet Sensor from mSILAR-Processed Sn-ZnO
( Springer New York LLC , 2017 , Article)Microwave-assisted successive ionic layer adsorption and reaction was employed to synthesize Sn-ZnO (tin-doped zinc oxide), and its sensitivity to ultraviolet radiation is compared with zinc oxide (ZnO). The sensing films ... -
