Analog CMOS implementation of cellular neural networks
(Bilkent University, 1991)
An analog CMOS circuit realization of cellular neural networks with transconductance
elements is presented in this thesis. This realization can be easily
adapted to various types of applications in image processing by ...
A rhythm analysis method for exercise electrocardiograms
(Bilkent University, 1996)
Exercise electrocardiography (the exercise ECG test or the stress EGG test)
is one of the most popular and the most important non-invasive diagnostic tests
in the field of cardiovascular disease. Arrhythmia analysis is ...
A dynamic importance sampling method for quick simulation of rare events
(Bilkent University, 1993)
Simulation of low-probability events may take extremely long times since they
occur very rarely. There are various variance reduction methods used to speed
up simulations in such cases. In this thesis, a new variance ...
Design and stability of Hopfield associative memory
(Bilkent University, 1991)
This thesis is concerned with the selection of connection weights of Hopfield
neural network model so that the network functions as a content addressable
memory (CAM). We deal with both the discrete and the continuous-time ...
Nonlinear observer design with application to the synchronization of chaotic systems
(Bilkent University, 1996)
Observers cire used to estimate the states of dynamiccil systems whenever
are not available through direct measurements. Although the design of linear
observers is a well-developed branch of control theory, its counterpart ...
Implementation of a state-space Kalman filter on a digital signal processing microprocessor
(Bilkent University, 1990)
Simulation of DigiCipher, an HDTV system proposal
(Bilkent University, 1991)
In this thesis, the digital video encoder-decoder parts of an American
HDTV system proposal, DigiCipher^^'^ is simulated in an image sequencer,
based on the system description sheets. Numerical and subjective performances
are ...
Application of dither and observer based state feedback in the control of chaotic systems
(Bilkent University, 1996)
In the first part of this thesis, the application of dither for controlling chaotic
systems is presented. Dither is a high frequency periodic signal that has been
excunined in the literature before, for changing nonlinear ...
Analysis of dielectric waveguide bends and curved coupler structures using finite difference beam propagation method
(Bilkent University, 1997)
In this thesis, implicit finite difference beam propagation method based on Crank Nicholson
discretization procedure is implemented and applied to the analysis
of propagation of optical beams in an orthogonal bend and a ...
Online ECG signal orthogonalization based on singular value decomposition
(Bilkent University, 1996)
Electrocardiogram (ECG) is the measurement of potential differences occurring
on the body due to the currents that flow on the heart during diastole
and systole. Cardiac abnormalities cause uncommon current flows, leading ...
