In this study an improved behavioral modeling including even order terms is proposed to model asymmetric IMD components observed in the multi-tone excitation of nonlinear amplifiers. Only odd order model (OOM) and even order introduced model (EOM), proposed model, are constructed and compared for a sample amplifier. It is showed that introducing even order term is improved the model validity range and accuracy in addition to the decrease model polinomial order. © 2010 IEEE.

A normalized set of force and permeance data for doubly-salient magnetic geometries
Mahariq, İbrahim; Ertan, Hulusi Bülent; Department of Electrical and Electronics Engineering (2009)
In this study, a model is developed to represent doubly-salient magnetic circuits and to fit finite element analysis for the aim of obtaining a set of normalized normal force, tangential force, and permeance variation data. To obtain the desired data FE field solution method is used. The reliability of finite element results have been verified by three steps; first, comparing the numerical results with analytically calculated permeance, second, by solving two switch reluctance motors and comparing the resul...
Generalized Pushover Analysis For Torsionally Coupled Systems
Kaatsız, Kaan; Alıcı, Fırat Soner; Sucuoğlu, Haluk (2017-01-13)
Generalized pushover analysis procedure that was previously formulated on 2D planar frames is extended to 3D systems with torsional coupling in the presented study. The instantaneous force distribution acting on the system when the interstory drift at a story reaches its maximum value during seismic response is defined as the generalized force distribution. This force distribution is then expressed in terms of combinations of modal forces. Modal contributions to the generalized force vectors are calculated ...
A phase-field model for fracture of unidirectional fiber-reinforced polymer matrix composites
Denli, Funda Aksu; Gultekin, Osman; Holzapfel, Gerhard A.; Dal, Hüsnü (Springer Science and Business Media LLC, 2020-04-01)
This study presents a crack phase-field approach for anisotropic continua to model, in particular, fracture of fiber-reinforced matrix composites. Starting with the variational formulation of the multi-field problem of fracture in terms of the deformation and the crack phase fields, the governing equations feature the evolution of the anisotropic crack phase-field and the balance of linear momentum, presented for finite and small strains. A recently proposed energy-based anisotropic failure criterion is inc...
An accelerated BEM formulation for the forward problem solution of ESI using realistic head models
Akalm, Z; Gençer, Nevzat Güneri (2003-09-21)
In this study, the forward problem of electrical source imaging (ESI) is solved using the Boundary Element method (BEM) with realistic head models. The realistic model consists of scalp, skull, CSF, brain and eyes. To get more accurate results quadratic elements are used in the meshes-and a new method is proposed for the generation of the quadratic mesh. An accelerated method is proposed for the solution of the potential field.
A digital neuron realization for the random neural network model
CERKEZ, CUNEYT; AYBAY, HADİ IŞIK; Halıcı, Uğur (1997-06-12)
In this study the neuron of the random neural network (RNN) model (Gelenbe 1989) is designed using digital circuitry. In the RNN model, each neuron accumulates arriving pulses and can fire if its potential at a given instant of time is strictly positive. Firing occurs at random, the intervals between successive firing instants following an exponential distribution of constant rate. When a neuron fires, it routes the generated pulses to the appropriate output lines in accordance with the connection probabili...
