Frequency domain subspace identification of discrete-time singular power spectra
(2011)In this paper, we propose a subspace algorithm for the identification of linear-time-invariant discrete-time systems with more outputs than inputs from measured power spectrum data. The proposed identification algorithm ... -
A unified model for real-time data grids supporting distributed scheduling of jobs
(2011)There exist a number of simulators, emulators, and production platforms in the literature proposed for Grid computing. Each of them assumes different models; presents and supports their own list of functions. Yet, in the ... -
Trajectory tracking control of nonholonomic wheeled mobile robots: Combined direct and indirect adaptive control using multiple models approach
(2012)This paper presents a novel methodology for the trajectory tracking control of nonholonomic wheeled mobile robots using multiple identification models. The overall control system includes two stages. In the first stage, a ... -
Compact implementation of threefish and Skein on FPGA
(2012)The SHA-3 finalist Skein is built from the tweak able Threefish block cipher. In order to have a better understanding of the computational efficiency of Skein (resource sharing, memory access scheme, scheduling, etc.), we ... -
Simulation of real-time Data Grid systems via DGridSim simulator
(2012)In this study, DGridSim simulator will be introduced and some example simulation results will be presented. DGridSim can simulate four different Data Grid system organizations. Furthermore, for every system organization, ... -
Strong stabilization of time-delay systems
(IFAC Secretariat, 2012)Stable controllers are required due to modelling imperfections and for better performance achievements. As is well known, a stable stabilizing controller for a given real-rational plant exists if and only if the plant ... -
Content-based image retrieval of centroblast cells and noncentroblast cells in Follicular lymphoma [Sentroblast ve sentroblast olmayan folli·küler lenfoma hücre resi·mleri·ne i·çeri·k tabanli geri· eri·şme]
(2012)In this study content-based image retrieval is applied to hematoxylin and eosin H&E stained Follicular lymphoma centroblast cell images and K-nearest neighbour classifier is used with multi-texton histogram features. With ... -
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 ... -
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 ... -
