Abstract : The idea of multiprocessor is a technique or mechanism that is implemented for long years, but with the need for increasing of computational speed and accuracy, taking into account that the progress in technique in this field is rare in Iraq. This encouraged the implementing of this work in order to build a DSP kit helping Iraqi researcher at universities in their search with minimum cost.
Abstract : The aim of this thesis is to design an effective and easy-to-handle system to analyze signals that contain subharmonic frequency components in its spectrum using a micro-computer based system. Subharmonic generation is widely occurring for low frequency bands especially at power frequencies, 50 Hz or 60 Hz, when these signals are used in energy processing. One of the famous techniques is called integral-cycle control or Amplitude Modulation of power signal.
Abstract : The impressive development of computer networks has reached the point where security becomes essential importance for every user and organization that want to exchange data in a secured way. Today, one of the latest secure communication methods for organizations that are motivated to reduce costs and increase services is the Virtual Private Network (VPN). The VPN mechanism is based on two newest technologies, IPSec and IKE where, IPSec is a suite of protocols used to protect information and IKE is a protocol to exchanged data.
