Spectral estimation in frequency-domain by subspace techniques
(Elsevier Science BV, 2014)In this paper, frequency-domain subspace-based algorithms are proposed to estimate discrete-time cross-power spectral density (cross-PSD) and auto-power spectral density (auto-PSD) matrices from samples of the Welch cross-PSD ... -
Nuclear Norm Spectrum Estimation From Uniformly Spaced Measurements
(IEEE-Inst Electrical Electronics Engineers Inc, 2014)Subspace-based methods have been effectively used to estimate multi-input/multi-output, discrete-time, linear-time invariant systems from uniformly spaced spectrum samples. A critical step in these methods is the splitting ... -
Identification of continuous-time power spectra by generalized Fourier series
(Chinese Automatic Control Soc, 2007)In this paper, we present a generalized Fourier series based algorithm for the identification of continuous-time, linear-time invariant systems from power spectrum measurements. The algorithm is strongly consistent and it ... -
An analysis of transformer excitation current under nonsinusoidal supply voltage
(IEEE-Inst Electrical Electronics Engineers Inc, 2002)In this paper, the effect of nonsinusoidal supply voltage on the core loss and the transformer excitation current is investigated. The time-domain waveform of the transformer excitation current is calculated for a worst-case ... -
Automatic recognition of scenes with power line wires in real life aerial images using DCT-based features
(Academic Press Inc Elsevier Science, 2018)This paper presents results of power line scene detection methods that use new feature extraction/selection strategies based on Discrete Cosine Transform (DCT) of scenes obtained from aircraft-based cameras. Whenever a ... -
A Self Organizing Map Based Approach for Congestion Avoidance in Autonomous Ip Networks
(Acad Sciences Czech Republic, Inst Computer Science, 2015)This work presents a Self Organizing Map (SOM) based queue management approach against congestion in autonomous Internet Protocol (IP) networks. The new queue management approach is proposed with consideration to the pros ... -
Feature extraction, selection and classification code for power line scene recognition
(Elsevier Science BV, 2018)Detection and avoiding of power lines and cables is a critical issue in aircraft flight safety. Despite various improvements in image analysis literature, most of the safety issues depend on visual capabilities of pilots. ... -
MUSIC Algorithm for Respiratory Rate Estimation Using RF Signals
(İstanbul University, Fac Engineering, 2018)Continuous monitoring of respiratory rate (cycle) during sleep for diseases such as sleep apnea and sudden infant death syndrome (SIDS) can be lifesaving. Wireless radio communications signals are everywhere and can be ... -
Prediction of partial synchronization in delay-coupled nonlinear oscillators, with application to Hindmarsh-Rose neurons
(IOP Publishing LTD, 2013)The full synchronization of coupled nonlinear oscillators has been widely studied. In this paper we investigate conditions for which partial synchronization of time-delayed diffusively coupled systems arises. The coupling ... -
Robust flow control in data-communication networks with multiple time-delays
(Wiley, 2010)Robust controller design for a flow control problem where uncertain multiple time-varying time-delays exist is considered. Although primarily data-communication networks are considered, the presented approach can also be ... -
Stable H-infinity flow controller design using approximation of FIR filters
(SAGE Publications LTD, 2012)Stable flow controllers are usually preferred since, compared with unstable flow controllers, they are less sensitive to any modelling imperfections. H-infinity-optimal flow controllers involve finite impulse-response (FIR) ... -
Performance and Robustness of Flow Controllers Designed Using Non-causal Uncertainty Blocks
(Wiley, 2013)According to some recent results, use of non-causal uncertainty blocks may be advantageous in the robust controller design of systems with multiple uncertain time-delays. In this work, performance and robustness improvements ... -
Performance level and stability margins of an optimal H-infinity flow controller
(SAGE Publications LTD, 2012)Flow controllers are needed to avoid congestion in different types of networks. The dynamics of such networks, however, can usually be represented by infinite-dimensional models, which are either based on partial-differential ... -
Stable H-infinity controller design for systems with multiple input/output time-delays
(Pergamon-Elsevier Science LTD, 2012)The stable H-infinity controller design problem is considered for multi-input-multi-output systems with multiple input/output time-delays. An algorithm is presented to solve this problem. The algorithm makes use of the ... -
A small gain theorem for systems with non-causal subsystems
(Pergamon-Elsevier Science LTD, 2008)Small gain theorems are used to verify the stability of a feedback interconnection of causal stable systems. In this work, we extend the small gain condition to test the stability of a feedback interconnection of two stable ... -
Characterization and Computation of Partial Synchronization Manifolds for Diffusive Delay-Coupled Systems
(Siam Publications, 2016)Sometimes a network of dynamical systems shows a form of incomplete synchronization, characterized by synchronization of some but not all of its component systems. This type of incomplete synchronization is called partial ... -
Comparison of PI controllers designed for the delay model of TCP/AQM networks
(Elsevier Science BV, 2013)One of the major problems of communication networks is congestion. In order to address this problem in TCP/IP networks, Active Queue Management (AQM) scheme is recommended. AQM aims to minimize the congestion by regulating ... -
Evaluating and Approximating FIR Filters: An Approach Based on Functions of Matrices
(IEEE-Inst Electrical Electronics Engineers Inc, 2015)Most of the controllers designed for systems with timedelays involve finite impulse response (FIR) filters in their structure, in particular prediction based controllers for systems with input/output delays. We present ... -
Aspects of achievable performance for quarter-car active suspensions
