Micromechanical modeling of semicrystalline polymers with spherulite morphology
Oktay, Hasan Emre; Göktepe, Serdar; Gürses, Ercan; Department of Civil Engineering (2020-10-23)
In this study, a micromechanical constitutive model for semicrystalline polymers is developed. The proposed model considers interactions among the adjacent regions at the same length scale. The neighborhood information is obtained from the well characterized spherulite morphology of polyethylene. Deformation characteristics of a disk-like spherulite model that has similarities with the considered modeling approach are studied using the finite element method. The model discretizes a disklike spherulite i...
2D simulation studies and initial experimental results for hall effect imaging /
Gözü, Mehmet Soner; Gençer, Nevzat Güneri; Department of Electrical and Electronics Engineering (2014)
In this thesis, 2D simulation studies of Hall Effect Imaging (HEI) technique using linear phased array transducer are performed and initial experimental results are obtained. The goal of HEI is to image the conductivity distribution in biological bodies. For this purpose, HEI uses the interaction of ultrasound with a static magnetic field to generate velocity current density distribution inside the body. Due to the velocity current density, a resultant voltage is sensed by electrodes attached on the surface...
Heavy mesons in heavy quark effective theory
Elpe, Altuğ; Özpineci, Altuğ; Department of Physics (2016)
In this thesis heavy quark effective theory is studied. Typical interaction momentum between constituents of a meson is about 300MeV where QCD is in its nonperturbative region. Although there is no solution to QCD in this region information can be obtained by using effective field theories. The heaviest quarks have mass much greater than QCD. This property is used to construct an effective field theory in the infinite mass limit by modifying the QCD Lagrangian. The residual motion and the spin interactions...
Photoluminescence properties of Si nanocrystals embedded in SiO2 matrix
Seyhan, Ayşe; Turan, Raşit; Department of Physics (2010)
This thesis examines the luminescence properties of nanoscale silicon (Si) by using spectroscopic techniques. Since the development of new optical devices requires understanding light emission mechanism optical spectroscopy has become more important tool in the analysis of these structures. In this thesis, Si nanocrystals embedded in SiO2 matrix will be studied. Photoluminescence (PL) and Time-resolved photoluminescence spectroscopy (TRPL) have been used to detect the light emission in UV-Vis-NIR range. Exp...
Hybrid wavelet-neural network models for time series data
Kılıç, Deniz Kenan; Uğur, Ömür; Department of Financial Mathematics (2021-3-3)
The thesis aims to combine wavelet theory with nonlinear models, particularly neural networks, to find an appropriate time series model structure. Data like financial time series are nonstationary, noisy, and chaotic. Therefore using wavelet analysis helps better modeling in the sense of both frequency and time. S&P500 (∧GSPC) and NASDAQ (∧ IXIC) data are divided into several components by using multiresolution analysis (MRA). Subsequently, each part is modeled by using a suitable neural network structure. ...
