Boolean Functions Simplification Algorithm of O(n) Complexity

  • Şirzat Kahramanli and
  • Fatih Başçiftçi

1 December 2003

The minimization of Boolean functions allows designers to make use of fewer components, thus reducing the cost of particular system. All procedures for reducing either two-level or multilevel Boolean networks into prime and irredundant form have O(2n...

The Monitoring Simulation of a Lathe

  • George C. Balan and
  • Calm Tarau

1 December 2003

The study of machine-tool dynamic is realised here as “monitoring”, meaning checking and improving the functioning of the machine. The state of processing is followed with certain sensors which signs are processed inside the computer, then it takes t...

A Windows-Based Digital Filter Design

  • Yüksel Özbay,
  • Bekir Karlik and
  • A. Resit Kavsaoglu

1 December 2003

This study aims to describe a general digital filter, practically for Windows’ users. For this purpose. an I/O interfacing circuits base on PIC16F877 was designed to receive analog signal into the PC and return filtered signals. This I/O module was t...

Application of FFT and Arma Spectral Analysis to Arterial Doppler Signals

  • Elif Derya Übeyli,
  • Hakan Işık and
  • İnan Güler

1 December 2003

In this study, Doppler signals recorded from arteries of 105 subjects were processed by PC-computer using fast Fourier transform, and least squares modified Yule-Walker autoregressive moving average methods. By using these spectrum analysis techniqu...

The Resonance Analysis Caused by Harmonics in Power Systems Including Thyristor Controlled Reactor

  • Ramazan Yüksel,
  • Mehmet Uzunoğlu,
  • Celal Kocatepe and
  • Mehmet Argin

1 December 2003

The static VAR compensators having fixed capacitor thyristor controlled reactor (FC-TCR) used to improve voltage stability in power systems are nonlinear elements. The fixed capacitor group will produce reactive power while the thyristor controlled r...
