Region covariance descriptors calculated over the salient points for target tracking [Hedef i·zleme i·çi·n önemli· noktalar üzeri·nden hesaplanan bölgesel ortak degi·ş i·nti· beti·mleyi·ci·leri·]
(2012)Features extracted at salient points in the image are used to construct region covariance descriptor (RCD) for target tracking purposes. In the classical approach, the RCD is computed by using the features at each pixel ... -
Application of the discriminative common vector approach to one sample problem [Ayirtedi·ci· ortak vektör yaklaşiminin tek örnek problemi·ne uygulanmasi]
(2012)Matrix-based (2D) methods have advantages over vector-based (1D) methods. Matrix-based methods generally have less computational costs and higher recognition performances with respect to vector-based variants. In this work ... -
Cable and wire detection system for aircrafts [Hava araçlari için tel ve kablo tespit sistemi]
(2013)EDlines is a robust and accurate line segment detector that is known to run 11 times faster than the popular (and fastest known) method of LSD, while avoiding necessity of parameter adjustments. In this work, this detector ... -
On the efficiency issues of virtual keyboard design
(2012)Virtual keyboards are useful tools, which ease effortless entry of textual data and enable typing with alternative input hardware such as a single switch. Early virtual keyboards are designed similar to physical keyboards ... -
Design of a scenario-based synthetic mixed pulse generator [Senaryo tabanli bir sentetik darbe üreteci tasarimi]
(2013)Electronic Support Measures (ESM) plays an important role in modern Electronic Warfare (EW) systems. The main purpose of an ESM system is to intercept as many emissions as it can, and then to deinterleave mixed streams of ... -
On increasing the computational efficiency of long integer multiplication on FPGA
(2012)This paper presents a compact hardware architecture for long integer multiplication and proposes a strategy to increase the computational efficiency of the Karatsuba algorithm on FPGA. The presented architecture aims to ... -
Robust servomechanism problem for neutral distributed time-delay systems
(2012)An important ptoblem in control engineering is to design a controller which stabilizes a given system and achieves robust tracking of a reference signal despite certain disturbance signals. The present paper considers this ... -
An application for the control of stochastic petri nets via fluidification approach
(2012)Petri nets are frequently used for modeling and analysis of discrete event systems. Similar to other modeling formalisms for discrete systems, it suffers from state explosion. Fluidification can be used to overcome this ... -
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 ... -

(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
