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 ...
Evaluation of thermal history and defect in friction stir processing of as-cast magnesium AZ91
(
Trans Tech Publications Ltd
, 2018 , Conference Paper)
Friction stir processing (FSP) is a thermos-mechanical process for modifying the microstructural and material properties of metals. FSP also can be used for mechanical alloying and producing metal matrix composites. Due ...
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 ...
Resonator based switching technique between ultra wide band (Uwb) and single/dual continuously tunable-notch behaviors in uwb radar for wireless vital signs monitoring
(
MDPI AG
, 2018 , Article)
This paper presents a novel resonator that can switch and create three important behaviors within the same antenna using miniaturized capacitors. The resonator was integrated into conventional Ultra-Wide Band (UWB) antenna ...
Electrochemical, morphological, and spectroscopic study of poly(aniline-co-o-bromoaniline) (PA-co-o-BrA) conducting copolymer
(
Institute for Ionics
, 2018 , Article)
A series of moderately conducting and soluble copolymers of poly(aniline-co-o-bromoaniline) (PA-co-o-BrA) having different compositions was obtained by in the situ copolymerization method using different concentrations of ...
Post-buckling analysis of piezo-magnetic nanobeams with geometrical imperfection and different piezoelectric contents
(
Springer Verlag
, 2019 , Article)
Thermal post-buckling behavior of a geometrically imperfect/perfect piezo-magnetic nano-scale beams made of two-phase composites is analyzed in the present paper based on nonlocal elasticity theory. For the first time, the ...
Stochastic analysis of interphase effects on elastic modulus and yield strength of nylon 6/clay nanocomposites
(
Springer Netherlands
, 2019 , Article)
The multifunctional properties of polymer clay nanocomposites (PCNs) can be related to the interaction of clays, polymer and interphase region. Several experimental, analytical and numerical studies have been conducted to ...
Synthesis and Characterization of Polyaniline, Poly(3-fluoroaniline), and Poly(aniline-co-3-fluoroaniline) Derivatives Obtained by Chemical Oxidative Polymerization Methods
(
Taylor and Francis Inc.
, 2018 , Article)
The syntheses of thermally stable, conducting polyaniline, poly(3-fluoroaniline), and poly(aniline-co-3-fluoroaniline) derivatives by chemical oxidative polymerization methods are described. By varying the mol% of ...
