The standard Schottky noise approach alone is not sufficient to describe the noise mechanism in an InAs/GaSb superlattice photodetector at reverse negative bias. The additional noise identified appears at surface activation energies below 60 meV and is inversely proportional to the reverse bias. In order to satisfactorily explain the experimental data, we hereby propose the existence of a surface recombination noise that is a function of both the frequency and bias. The calculated noise characteristics indeed show good agreement with the experimental data. (C) 2013 The Japan Society of Applied Physics

Uncertainty in Nonlinear SDoF Response Due to Long-Period Noise of Accelerograms Akkar, Dede Sinan; Guelkan, Polat; Kale, Oezkan (2009-07-01) 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 ca...
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...
Noise Estimation for Hyperspectral Imagery using Spectral Unmixing and Synthesis DEMİRKESEN, CAN; Leloğlu, Uğur Murat (2014-09-25) Most hyperspectral image (HSI) processing algorithms assume a signal to noise ratio model in their formulation which makes them dependent on accurate noise estimation. Many techniques have been proposed to estimate the noise. A very comprehensive comparative study on the subject is done by Gao et al. [1]. In a nut-shell, most techniques are based on the idea of calculating standard deviation from assumed-to-be homogenous regions in the image. Some of these algorithms work on a regular grid parameterized wit...
Optimal passive and hybrid control of vibrations and sound radiation from linear and non linear PZT based smart structures Özer, Mehmet Bülent (2002-03-21) Two different methods are introduced for the determination of optimal active control inputs and passive shunting parameters in the PZT-based smart structure vibration and sound pressure control problems. The first method makes use of the dynamic vibration absorber principle; the second method uses the receptance of the open circuit structure-PZT system for determination of active control laws and parameters of optimal passive shunting. The advantages of each method are discussed. Using both methods, optimal...
Numerical and experimental investigation of tubeaxial fan noise Bodur, Ahmet; Çalışkan, Mehmet; Department of Mechanical Engineering (2014) In this study, the noise characteristic of a tube axial fan is investigated numerically and experimentally. The effects of blockage plate in front of the tube axial fan on the tube axial fan noise level are experimentally investigated. A computational aero-acoustic method is used to predict the flow induced fan noise. This method couples a flow solver and a wave equation solver. Unsteady flow analysis is performed with URANS (Unsteady Reynolds Average Navier Stokes Equation) method while acoustics radiation...
