Common usage of nonlinear loads creates an important power quality problem, called harmonics. Up to recent years, harmonics related problems are tried to be solved by passive filters which have some drawbacks for both ...

Because they are invariant under rotation, Zernike moments are widely used for shape recognition in two-dimensional images. Similarly, magnitudes of 3D Zernike moments have the analogous property in three dimensional images. ...

In communications, some properties of the transmitted signal has to be known in receiver side so that the information in the transmitted signal could be extracted. But in some cases, there is no prior information about the ...

In this paper, the design and implementation of a dsPIC microcontroller-based photovoltaic (PV) microinverter using direct digital synthesis technique has been presented. The flyback PV microinverter is controlled via a ...

In this thesis study, firstly step recovery diode theory have been investigated and operation principle of SRD has been given detailed. In the next step, design of frequency multipler circuit with SRD are analyzed using ...

Inertial navigation system determines position, velocity and attitude by using navigation equations and inertial measurement unit outputs. Accumulation of sensor errors propagated by integration becomes very crucial in ...
