Prediction of partially synchronous regimes of delay-coupled nonlinear oscillators?
(2013)We present an approach which allows to accurately predict both the occurrence and type of partially synchronous regimes of delay-coupled non-linear oscillators. Unlike the conventional approach, we build on an analysis of ... -
A necessary and sufficient condition for the stabilization of decentralized time-delay systems by time-delay controllers
(2013)It has recently been shown that a necessary and sufficient condition for the stabilization of a linear time-invariant (LTI) retarded time-delay system by LTI decentralized finite-dimensional controllers is that the system ... -
Decentralized robust control of systems interconnected over networks
(2013)Due to recent technological developments, systems which are interconnected over networks have become very common. Typically, a number of subsystems may be interconnected by means of an existing network. Furthermore, each ... -
Supervisory controller design to enforce basic properties in timed-place petri nets
(2013)Supervisory controller design to enforce boundedness, reversibility, and liveness in discrete-event systems with time-delays is considered. It is assumed that the system is modeled by a timed-place Petri net. The approach ... -
Determinaton of the number of vehicles using unmanned aerial vehicles [Insansiz hava araçlari kullanilarak araç sayisi tespiti]
(IEEE Computer Society, 2014)This paper includes an application of the four rotor unmanned aerial vehicle names as quadrocopter. This application is determination of the traffic density depending on the number of vehicle in the certain area. For this ... -
Modular common vector approach [Modüler ortak vektör yaklaşimi]
(IEEE Computer Society, 2014)The performance of a face recognition system is negatively affected by the accessories used on the face. Like many methods, the recognition performance of the Common Vector Approach (CVA) [1] over occluded images is not ... -
GRID matching in Monte Carlo Bayesian compressive sensing
(2013)Sparse signal reconstruction from compressive measurements assumes a grid of possible support points from which to estimate the signal support set. However, reconstruction of high measurement resolution waveforms is very ... -
Decentralized controller design by continuous pole placement for commensurate-time-delay systems
(IFAC Secretariat, 2014)Decentralized controller design problem for linear time-invariant retarded commensurate-time-delay systems is considered. The continuous pole placement algorithm, which has recently been introduced for static state vector ... -
Inclusion principle and overlapping decompositions of distributed-time-delay systems
(IFAC Secretariat, 2014)The inclusion principle for distributed-time-delay systems is defined. The properties of input-output map equivalence and preservation of stability between two systems, one of which includes the other, are presented. ... -
Detection of low probability of intercept signals in low SNR using multichannel sensor arrays [Tespit olasiligi düşük sinyallerin düşük SNR altinda çok-kanalli sensör dizileri ile tespiti]
(IEEE Computer Society, 2014)In this paper, a method is proposed for the detection of low probability of intercept, LPI signals in high noise without prior knowledge and assumption using spatially distributed multichannel wideband sensor array. The ... -
Algorithms and software for approximating and evaluating fir filters
(Institute of Electrical and Electronics Engineers Inc., 2014)The controllers designed for time-delays systems often involve finite impulse response (FIR) filters, in particular prediction based controllers for systems with input/output delays. We present algorithms and software to ... -
A combined direct and indirect adaptive control scheme for a wheeled mobile robot using multiple models
(Springer Verlag, 2014)This chapter presents a method about trajectory tracking control of a nonholonomic wheeled mobile robot. The main focus of the chapter is to improve the transient response for the trajectory tracking control of mobile ... -
Two dimensional (2D) subspace classifiers for image recognition
(2006)The Class-Featuring Information Compression (CLAFIC) is a pattern classification method which uses a linear subspace for each class. In order to apply the CLAFIC method to image recognition problems, 2D image matrices must ... -

Robust control design for time-delay systems using non-causal uncertainty blocks
(Institute of Electrical and Electronics Engineers Inc., 2014)Robust controller design problem for time-delay systems is considered. Both the time-delays, which may appear at the inputs and/or outputs of the plant, and the finite-dimensional part of the plant are assumed to be subject ... -
A 2-D orientation-adaptive prediction filter in lifting structures for image coding
(2006)Lifting-style implementations of wavelets are widely used in image coders. A two-dimensional (2-D) edge adaptive lifting structure, which is similar to Daubechies 5/3 wavelet, is presented. The 2-D prediction filter predicts ... -
