A noise reduction algorithm in ECG signals using wavelet transform
(Ieee, 1998)
A noise reduction algorithm based on multiresolution orthogonal wavelet transform in ECG signals is discussed. The results are presented for different analysis and synthesis filter coefficients proposed by Vetterli-Herley ...
Improving performance of switched reluctance motor by fuzzy logic controller
(John Wiley & Sons Ltd, 1999)
This paper presents torque ripple minimization of a switched reluctance motor (SRM) by using a fuzzy controller, The nonlinear model of the SRM and the mathematical model of the converter circuit are driven. The motor used ...
A multiobject tracking framework for interactive multimedia applications
(Ieee-Inst Electrical Electronics Engineers Inc, 2004)
Automatic initialization and tracking of multiple people and their body parts is one of the first steps in designing interactive multimedia applications. The key problems in this context are robust detection and tracking ...
New natural observer applied to speed-sensorless DC servo and induction motors
(Ieee-Inst Electrical Electronics Engineers Inc, 2004)
A simple observer design technique with parameter adaptation is proposed for bounded-input bounded-output nonlinear systems. In this technique, no feedback is used in the observer but parameter estimations are considered ...
Design of a circular piezoelectric transformer with crescent-shaped input electrodes
(Inst Pure Applied Physics, 2003)
In this study, a new disk-type piezoelectric transformer design is proposed. The input side of the transformer has a crescent-shaped electrode and the output side has a focused poling direction. The electrodes and poling ...
A piezoelectric motor using two orthogonal bending modes of a hollow cylinder
(Ieee-Inst Electrical Electronics Engineers Inc, 2002)
This paper proposes a compact ultrasonic motor with low manufacturing costs, a simpler driving circuit, and scalability. The stator of the motor presented in this paper consists of a hollow metal cylinder, whose outside ...
Adaptive neuro-fuzzy inference systems (ANFIS) application to investigate potential use of natural ventilation in new building designs in Turkey
(Pergamon-Elsevier Science Ltd, 2007)
Natural ventilation in living and working places provides both circulation of clear air and a decrease of indoor temperature, especially during hot summer days. In addition to openings, the dimension ratio and position of ...
Application of an adaptive neuro-fuzzy inference system for classification of Behcet disease using the fast Fourier transform method
(Blackwell Publishing, 2007)
In this study, ophthalmic arterial Doppler signals were obtained from 200 subjects, 100 of whom suffered from ocular Behcet disease while the rest were healthy subjects. An adaptive neuro-fuzzy inference system (ANFIS) was ...
A bicriteria scheduling problem with a learning effect: Total completion time and total tardiness
(Taylor & Francis Inc, 2007)
This paper considers a bicriteria scheduling problem with a learning effect on a single machine to minimize a weighted sum of total completion time and total tardiness. A mathematical programming model is developed for the ...
Application of fuzzy logic for load frequency control of hydroelectrical power plants
(Pergamon-Elsevier Science Ltd, 2007)
The quality of generated electricity in power systems is dependent on the system output, which has to be of constant frequency and must maintain the scheduled power and voltage. Therefore, load frequency control, LFC, is ...
