    Abstract: In this paper, three-phase short-circuit at the terminals of a superconducting synchronous generator is simulated by using MATLAB. In this simulation, a single screened superconducting generator directly connected to power system is considered and two operating cases are investigated: the first case is that the fault is permanent and the second cas...

    Abstract: Passive radars get benefit from transmitter signals in the environment for target detection. One of the most important challenges in these radars is multipath and direct path interferences that enter the target and reference antennas. This article expressed the types of weakening, and multi-step structure to mitigate the mentioned signals in passiv... Show More

    Abstract: To solve the problem of segmenting an image into homogeneous regions with large area, this paper proposes an efficient algorithm that is based optimization base on modularity and super pixel method. Due to the fact that a very small areas of the image before segmentation, the proposed algorithm automatically merged with neighboring small areas and ... Show More

    Abstract: Currently, there are many ways to save energy for the switch such as change the operating modes to low power modes: SLEEP PORT and SLEEP SWITCH when there is no traffic flowing through the Ethernet ports. The switch will be waked up to normal modes when traffic flows pass through it. However, the changes of the modes of the OpenFlow Switch will cre... Show More

    Abstract: In the actual communication system, the line echo is a frequent problem, so the line echo canceller is necessary. Traditionally, the cancellers are designed according to line noises based on the Gaussian noise model. However, the noises do not obey the Gaussian distribution; therefore the performances of algorithms decrease, even cannot be used. In... Show More
