Method of moments formulated with electric field integral equation is used tocompute the induced surface currents and radar cross section and improvementsfor decreasing computing time are performed. In method of moments ...

In this work, attitude control problem of satellites which are assumed to be as rigidbodies is addressed. Satellite attitude is represented in terms of quaternions. Due tothe nonlinear nature of satellites and in the case ...

This study aims to investigate software based GPS receivers. In order to investigate software based GPS receivers, GPS system concepts, GPS signal structure and GPS receiver structure are studied. MATLAB models are implemented ...

At this work, a low phase noise voltage controlled oscillator designed and implemented. The purpose of this work is to design a low phase noise voltage controlled oscillator which has 2.8 GHz center frequency 200 MHz ...

Uncertainties, parameter changes and disturbances caused by the system structure and or changing operating conditions lie among the most frequently encountered problems in practical control applications. Sliding mode control ...

Measurement process can be thought as comparison of a quantity whose magnitude is required to be known with the available reference magnitude of the same quantity. However, this available reference may diverge form its ...

It is important to understand the structure of ionosphere for modeling and monitoring the variability of the ionosphere. Therefore, the remote sensing and monitoring systems must be operated continuously. TEC is one of the ...

Periodic waveforms are necessary for many applications like telecommunication, electromagnetic and biomedical. Direct Digital Synthesis (DDS) is a method of generating signals with high frequency resolution and fast frequency ...

In this study, in the most general sense, the finite state control for the semi active knee prosthesis with MR cylinder is realized. For this purpose, the similarities between gaits with the prosthetics and the normal gaits ...

The movement of biological macro-molecules is very dynamic due to their st-ructural evolution and interaction with other molecules. Atomic force microscopesare used to obtain images at nanometer and sub nanometer ranges. ...
