Dynamic response of metal foam FG porous cylindrical micro-shells due to moving loads with strain gradient size-dependency
(
Springer Verlag
, 2019 , Article)
The dynamic characteristics of functionally graded (FG) metal foam cylindrical micro-scale shells in contact with a moving load will be analyzed thorough this paper accounting for strain-gradient size-dependency. In the ...
Dynamic response of functionally graded graphene nanoplatelet reinforced shells with porosity distributions under transverse dynamic loads
(
Institute of Physics Publishing
, 2019 , Article)
This article investigates forced vibrational characteristics of a porous nanocomposite shell reinforced by graphene platelets (GPLs) under radial dynamic loads. Material properties of the shell dependents on uniform and ...
Poly(aniline-co-3-aminophenol): enhanced crystallinity and solubility
(
Springer Verlag
, 2019 , Article)
An improvement of physiochemical properties such as solubility, crystallinity, and the surface morphology of the copolymer have been achieved via the in-situ copolymerization of the monomers units using ammonium persulfate ...
Poly(aniline-co-2-hydroxyaniline): towards the thermal stability and higher solubility of polyaniline
(
Springer Verlag
, 2019 , Article)
Here, we adopted a donor-acceptor criteria for charge transfer and synthesize the thermally stable copolymers of poly(aniline-co-2-hydroxyaniline) (PA-co-2-HA) by in-situ copolymerization method having different compositions. ...
Monitoring and control of beta-distributed multistage production processes
(
Taylor and Francis Ltd.
, 2019 , Article)
Multistage statistical process control (SPC) is an effective procedure for ensuring quality of products in multistage manufacturing processes. Effective SPC approaches for monitoring and controlling quality in multistage ...
Nonlinear free and forced vibrations of graphene nanoplatelet reinforced microbeams with geometrical imperfection
(
Springer Verlag
, 2019 , Article)
Nonlinear free/forced vibration of a functionally graded graphene nanoplatelet (GNP) reinforced microbeam having geometrical imperfection which is rested on a non-linear elastic substrate have been studied in the present ...
An adaptive thresholding-based process variability monitoring
(
Taylor and Francis Inc.
, 2019 , Article)
In high-dimensional processes, monitoring process variability is considerably difficult due to the large number of variables and the limited number of samples. Monitoring changes in the covariance matrix of a multivariate ...
Thermal stability and frequency-dependent electrical conductivity of poly(aniline-co-m-nitroaniline)
(
Institute for Ionics
, 2019 , Article)
Herein, we report the frequency-dependent AC conductivity of poly(aniline-co-m-nitroaniline)s which were synthesized by chemical oxidation of aniline and m-nitroaniline using ammonium persulfate as an oxidizing agent by ...
Strain gradient based dynamic response analysis of heterogeneous cylindrical microshells with porosities under a moving load
(
Institute of Physics Publishing
, 2019 , Article)
Forced vibration of a porous functionally graded (FG) cylindrical microshell due to a moving point load with constant velocity is studied for the first time. Through the thickness of microshell, there are even-type or ...
Highly improved AC conductivity of poly(aniline-o-fluoroaniline)
(
Institute for Ionics
, 2019 , Article)
An improved frequency dependent AC-conductivity ng of poly(aniline-co-o-fluoroaniline)s (PA-co-o-FAs) has been recorded which are synthesized by in-situ copolymerization of aniline with o-fluoroaniline by oxidation of the ...
