Effect of temperature and graphene oxide on the swelling of PAAm-GO composite gels
(Avestia Publishing, 2019)
Graphene oxide (GO) is a two dimensional carbon material with similar one-atom thickness, and is a light material having extremely high strength and thermal stability [1]. Thus, GO is an efficient filler for the enhancement ...
Optical, Mechanical, and Electrical Properties of Polymer Composites Doped by Multiwalled Carbon Nanotubes
(Intechopen, 2016)
Three-dimensional networks can be hydrophilic and/or hygroscopic. Optical, mechanical, and electrical properties of these materials encompass many fields of technology. Composites of carbon nanotubes (CNTs) in polymeric ...
An improved hybrid feature reduction for increased breast cancer diagnostic performance
(Springer Verlag, 2014)
Methods: A hybrid method is proposed using the independent component analysis (ICA) and the discrete wavelet transform (DWT) to reduce feature vectors of Wisconsin diagnostic breast cancer (WDBC) data set. Two independent ...
Cohomological dimension and top local cohomology modules
(Rocky Mountain Mathematics Consortium, 2019)
Let R be a Noetherian ring, I an ideal of R and M an R-module. In this paper, we first determine a condition under which a given integer t is a lower bound for the cohomological dimension cd(I,M), and use this to conclude ...
Effects of hyperspectral image compression methods on classification
(Institute of Electrical and Electronics Engineers Inc., 2018)
Because of having large data size in hyperspectral imaging, compression becomes an important necessity in terms of the transmission and storage of the data. There are several compression approaches proposed in the literature, ...
Single fed UWB sierpinski fractal monopole antenna array
(Institute of Electrical and Electronics Engineers Inc., 2019)
In this work, single fed uniformly spaced seven elements mod-3 Sierpinski gasket antenna array is designed using CST MWS (Computer Simulation Technology Microwave Studio). The designed antenna array is fed by an N type ...
ECG feature extraction based on the bandwidth properties of variational mode decomposition
(Iop Publishing Ltd, 2016)
It is a difficult process to detect abnormal heart beats, known as arrhythmia, in long-term ECG recording. Thus, computer-aided diagnosis systems have become a supportive tool for helping physicians improve the diagnostic ...
Detrended fluctuation thresholding for empirical mode decomposition based denoising
(Academic Press Inc Elsevier Science, 2014)
Signal decompositions such as wavelet and Gabor transforms have successfully been applied in denoising problems. Empirical mode decomposition (EMD) is a recently proposed method to analyze non-linear and non-stationary ...
Electrical, optical and mechanical properties of PS/GNP composite films
(Taylor & Francis Ltd, 2018)
In this study, the electrical, optical and mechanical properties of polystyrene (PS) thin films added graphene nanoplatelet (GNP) have been investigated. Surface conductivity (sigma), absorbance intensity (A) and tensile ...
Sequential Combinations of Multiple Adaptive Lattice Filters in Cognitive Radio Channel Identification
(IEEE, 2017)
Sequential convex combinations of multiple adaptive lattice filters using different exponential weighting factors in cognitive radio channel identification framework have been considered in this presentation. First, the ...
