—A new public-domain simulator for mixed-signal circuits is described. The new simulator is very versatile, allowing the user to define new elements easily. The procedure adopted for simulation of circuits with both digital and analog elements is briefly discussed. Several simulation examples are presented to demonstrate the applications of the simulator.(More)
Next, the fourth generation of mobile communication will have the capability to support the mobile users either they belong to any wireless network. In fourth generation integration of network technologies for better services to mobile users is done .For example, Universal Mobile Telecommunication System (UMTS) which provides a large coverage area with low(More)
Moving vehicle detection is an essential process for Intelligent Transportation system. During the last decade, a large amount of work has been trying to produced output for this challenge; however, performances of most of them still fall far behind human perception. In this paper the object detection problem is studied, analyzing and reviewing the most(More)
In the age of multimedia and high-speed networks, multicast is one of the mechanisms by which the power of the Internet can be further harnessed in an efficient manner. When more than one receiver is interested in receiving a transmission from a single or a set of senders, multicast is the most efficient and viable mechanism. In the protocol stack of the(More)
