Detection of disturbances in energy system signals using gaussian distribution fitness test [Enerji Sisitemi Sinyallerinde Bozucularin Gauss Dagilim Uyumlulugu Testi ile Tespiti]
(2004)In this work, a method based on higher order statistics (HOS) is proposed to detect disturbances in energy system voltage and current waveforms due to faults and various system events. During the normal operation of the ... -
Evaluation of intersection collision warning system using an inter-vehicle communication simulator
(2004)An inter-vehicle communication (IVC) simulator has been developed to evaluate an intersection collision warning system. Various representative intersection collision scenarios are simulated. The physical and Media Access ... -
A comparison of static QoS-based scheduling heuristics for a meta-task with multiple QoS dimensions in heterogeneous computing
(2004)The problem of scheduling a set of independent tasks (a meta-task) with multiple QoS needs, such as Timeliness, Reliability, Versions, Security and Priority, in a Heterogeneous Computing (HC) environment is referred to as ... -
The size of the membership-set in a probabilistic framework
(Pergamon-Elsevier Science LTD, 2004)In this paper, we study the size of the membership-set for system identification in a probabilistic framework. Assuming that the regressors are persistently exciting and the measurement noise is a sequence of independent, ... -
Conversion of rate based flow control algorithms to window based algorithms
(IEEE, 2004)The conversion of rate based flow control algorithms used in high-speed data communication networks to window (credit) based algorithms is considered. A rate based robust flow controller, designed using the H-infinity ... -
Power quality event detection using joint 2-D-wavelet subspaces
(IEEE-Inst Electrical Electronics Engineers Inc, 2004)In this work, we present a novel two-dimensional (2-D) representation of power system waveforms for the automatic analysis and detection of transient events. The representation is composed of a matrix whose rows are formed ... -
Central and projection algorithms in identification with periodic set membership inputs
(IEEE, 2004)In this paper, we study the central and the projection algorithms in set membership identification with periodic input signals for the case that the number of the estimated parameters equals the input period. First, we ... -
Decentralized robust control basedon overlapping decompositions
(IFAC Secretariat, 2004)Use of overlapping decompositions in robust decentralized controller design is demonstrated. Using overlapping decompositions and expansions, a robustness bound to account for (i) the neglected interactions between the ... -
A program for analysis and control of Petri nets
(IEEE, 2004)Analysis and control algorithms are introduced for discrete-event systems which are modeled by Petri nets. A simulation and control design program is then developed to implement these algorithms. The program can simulate ... -
