The behavior of nonlinear oscillator deformations due to the long-period noise in strong ground motions is investigated. Inelastic spectral and residual displacements (SDIE and SDR, respectively) are selected to represent the nonlinear deformations of single-degree-of-freedom (SDoF) systems. Within this context, the interaction between these deformation demand parameters and high-pass filtering that is used for removing the long-period noise is examined. Analyses indicate that the high-pass filter values can influence the reliability of SDIE and SDR depending on the recording quality, level of inelasticity and magnitude variations. Usable spectral period ranges are proposed for SDIE through probabilistic methodologies where the adverse effects of high-pass filtering are minimal.

Numerical analysis of radio frequency inductively coupled ion thruster and computation of its performance parameters
Bozkurt, Erdal; Alemdaroğlu, Nafiz.; Department of Aerospace Engineering (2019)
The main goal of this thesis is geometric and parametric analysis of a simulated cylin-drical two-gridded Radio Frequency Inductively Coupled (RF-ICP) ion thruster. Inaddition, instrumental performance of this thruster and the effects of a fixed shapeof the electrodes on ion trajectories are investigated. The simulations of the plasmaand the ion optics are performed by using COMSOL Multiphysics software. The firststep is checking the reliability of the software. Radial and axial simulation parametricresults...
Estimation of high-frequency attenuation parameter (kappa) for hard rock stations of Turkish strong motion network
Akgün, Atınç Özgün; Gülerce, Zeynep; Özacar, Atilla Arda; Department of Civil Engineering (2021-2-12)
Site-specific decay in the Fourier Amplitude Spectrum (FAS) at high frequencies, a.k.a. the zero-distance kappa (κ0), is frequently used in seismic analysis of critical infrastructure; especially for the host-to-target adjustment of the design spectrum and the site response analysis. The zero-distance kappa value for hard rock sites is more crucial but harder to constrain because the amount of strong-motion stations on hardrock sites is limited in the global datasets. The objective of this study is to calcu...
Synchronization of nonlinearly coupled harmonic oscillators
Cai, Chaohong; Tuna, Sezai Emre (2010-07-02)
Synchronization of coupled harmonic oscillators is investigated. Coupling considered here is pairwise, unidirectional, and described by a nonlinear function (whose graph resides in the first and third quadrants) of some projection of the relative distance (between the states of the pair being coupled) vector. Under the assumption that the interconnection topology defines a connected graph, it is shown that the synchronization manifold is semiglobally practically asymptotically stable in the frequency of osc...
Improvement of finite element model by using sine vibration test results of acommunication satellite
Çekiç, Abdulkadir; Yaman, Yavuz; Department of Aerospace Engineering (2021-2-15)
In this thesis, the vibration analysis of a communication satellite is performed,and the improvementof the finite element model by using vibration test results is presented. First, the satellite finite element model isgenerated using MSC/PATRAN and MSC/NASTRAN commercial software. With the natural frequency and frequency response analysis, the expected frequency values and response amplitudes in accelerometers arecalculated in vibration tests. The results obtained in the vib...
NUMERICAL INVESTIGATION OF SPINNING MODE TRANSMISSION THROUGH VARIABLE AREA ANNULAR DUCTS WITH FLOW
Özyörük, Yusuf; Tester, Brian J. (2015-07-16)
Understanding sound propagation through variable area ducts continues to be important for controlling turbomachinery noise. In analytical treatment of the problem it is usually assumed that duct cross sections vary slowly and no mode scattering takes place. It is the purpose of this work to investigate numerically the effects of cross-sectional changes of varying degree on transmission of acoustic modes typical to turbomachinery. First, sound fields of interest through such ducts are obtained numerically by...
