A digital adaptive filter for detecting harmonic, active and reactive currents

Özdemir, Ayhan (IOP PUBLISHING LTD, 2004)

There have been a number of harmonic and reactive current-detecting methods for active power filters. All of these methods suffer from limitations such as being computationally costly or being sensitive to environmental ...
A dynamic wavelet network based adaptive load frequency control in power systems

Köklükaya, Etem (ELSEVIER SCI LTD, 2005)

This paper proposes a new adaptive load frequency controller based on a 'dynamic wavelet network (DWN)' that has lag dynamics, nonorthogonal mother wavelets as activation function and interconnection weights. A DWN is ...
A FPGA Based Remote Accessible Digital System Laboratory Prototype

M. Serdar Bascil; Yazıcı, İrfan; Temurtaş, Feyzullah (IEEE COMPUTER SOC, 2012)

In this work, a FPGA based remote accessible digital system laboratory prototype is created for Electrical & Electronics Engineering undergraduate students. The system consists of an Altera DE2 development and education ...
A New Approach for Calculation of PID Parameters with Model Based Compact Form Formulations

Özdemir, Ayhan; Erdem, Zekiye (KAUNAS UNIV TECHNOLOGY, 2014)

PID controller is a popular control method still widely used in process industry. In literature there are model/non-model based calculation methods for PID parameters. However, a model based analytic formulation in compact ...
A New Approach For Treatment of Chronic Obstructive Pulmonary Disease

Sedat Orenc; Uçar, Muhammed Kürşad; Bozkurt, Mehmet Recep; Bilgin, Cahit (IEEE, 2017)

Chronic Obstructive Pulmonary Disease (COPD) is a persistent respiratory disease usually caused by toxic gases. The diagnosis is made by a specialist doctor on a report taken by a specialist technician using a spirometer. ...
A New Approach For Treatment of Chronic Obstructive Pulmonary Disease

Sedat Orenc; Uçar, Muhammed Kürşad; Bozkurt, Mehmet Recep; Bilgin, Cahit (IEEE, 2017)

Chronic Obstructive Pulmonary Disease (COPD) is a persistent respiratory disease usually caused by toxic gases. The diagnosis is made by a specialist doctor on a report taken by a specialist technician using a spirometer. ...
A new classification approach using discriminant functions

Demirkol, Aşkın; Demir, Zafer; Emre, Erol (INST INFORMATION SCIENCE, 2005)

In this study, an approach involving new types of cost functions is given for the construction of discriminant functions. Centers of mass, not specified a priori, around feature vectors are clustered using cost function. ...
A NEW COST EFFECTIVE AND RAPID METHOD FOR THE MEASUREMENT OF BLOOD CULTURES

Düzenli, Gürsel; Karabay, Oğuz (GAZI UNIV, FAC ENGINEERING ARCHITECTURE, 2014)

Current automatized blood culture measurement systems are usually based on measurement of carbon dioxide with fluorescence. Long lasting measurement period and high cost are the major disadvantages of such methods. In this ...
A NEW COST EFFECTIVE AND RAPID METHOD FOR THE MEASUREMENT OF BLOOD CULTURES

Düzenli, Gürsel; Karabay, Oğuz (GAZI UNIV, FAC ENGINEERING ARCHITECTURE, 2014)

Current automatized blood culture measurement systems are usually based on measurement of carbon dioxide with fluorescence. Long lasting measurement period and high cost are the major disadvantages of such methods. In this ...
A new digital relay for generator protection against asymmetrical faults

Bayrak, Mehmet (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2002)

Under unbalanced conditions the three phase instantaneous power oscillates at twice the power system frequency. The magnitude of these oscillations can be used as a measure of the system unbalance. This paper has introduced ...
A new memristor-based low-pass filter topology and its small-signal solution using MacLaurin series

Yener, Şuayb Çağrı; Resat Mutlu; H. Hakan Kuntman (NATL INST OPTOELECTRONICS, 2015)

In this work, a new memristor-based low-pass filter topology is suggested. Memristor-based filters are nonlinear circuits and many of them cannot be solved analytically. To find an approximate analytical solution of the ...
A new security approach for public transport application against tag cloning with neural network-based pattern recognition

Düzenli, Gürsel (SPRINGER LONDON LTD, 2015)

RFID tags are widely used in situations where their counterfeiting or cloning can bring financial rewards. Cloning is a particular problem because it gets round the sophisticated security measures. This paper describes a ...
A novel chaotic attractor and its weak signal detection application

A. Gokyildirim; Uyaroğlu, Yılmaz; Pehlivan, İhsan (ELSEVIER GMBH, 2016)

In this paper, we present a new sinusoidal chaotic attractor and its weak signal detection application. This new system has a simple structure, parametric variety and high applicability. Its dynamic characteristics are ...
