The conductor geometry in double circuit lines makes them prone to multi-circuit faults like earthed and unearthed intercircuit faults and cross country faults. The probability of inter-circuit faults is increased when the multiple lines are mounted on the same tower. Mutual coupling is also present during un-earthed intercircuit faults. The phase-to-phase inter-circuit fault (without earth connection)...
Video matting is defined as the process of changing the background of the video by extracting the foreground image from each frame of a video. In this paper, we propose a video matting technique which uses Ncut segmentation technique to segment the frames. Further, Sobel edge detection technique is used on the segmented frames for detecting edges. Afterwards, Edge thickening process fills up all the...
Ad hoc wireless networks provide infrastructure-free communication, an efficient MAC protocol through which mobile stations can share a common broadcast channel is essential. Present medium access mechanism used are Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA), multiple access with collision avoidance (MACA) and CSMA/CA with RTS/CTS. These protocols are designed to reduce the collision...
Video matting can be described as a method of extracting the foreground object from each frame of a video and composite (or transfer) it to a different background or a different video. An automatic scribbling approach based on the motion of the foreground object in a video is introduced. Probability maps (PMs) are computed by analysing the motion of object in the video. In the proposed technique the...
Hidden node is a fundamental problem that affects any wireless network where nodes cannot hear each other and leads to data packet collision. IEEE 802.11 wireless networks employ RTS/CTS mechanism for avoiding DATA packet collision .The main design assumption in this method is that all the nodes in the vicinity of a sender and a receiver must hear the RTS and CTS packets. They also defer their transmission...
In this paper, we examine the scope of validity of the explicit self-organizing map (SOM) magnification control scheme of Bauer (1996) on data for which the theory does not guarantee success, namely data that are n-dimensional, nges2, and whose components in the different dimensions are not statistically independent. The Bauer algorithm is very attractive for the possibility of faithful representation...
