Research ArticleOpen accessAll words, across the recordMultiple-Input Multiple-Output Transmission Over a Multipath Faded ChannelsI.A.Z. QatawnehThe use of multiple antennas at the transmitter as well as at the receiver can greatly improve the capacity of a wireless link when operating in a rich scattering environment. In such an arrangement all transmitting antennas radiate in the same frequency band so the overall spectral efficiency becomes very high. Such a multiple antenna scheme, popularly known as Multiple … …American Journal of Applied Sciences, Vol. 10, Issue 3 · 11 Mar 2013 · 6,417 accessesView PDFCite

Research ArticleOpen accessAll words, across the recordPeer-to-Peer Video Conferencing Using Hybrid Content Distribution ModelAlhamza Munther, Salah Noori, Azlan Osman et al.Problem statement: Multimedia Conferencing System (MCS) is a server-based video conferencing system. One of the most critical limitations faced by this approach is the scalability issue. In the MCS, the outgoing bandwidth of the server is shared among all concurrent clients. Thus, the more clients there are, the lesser the bandwidth each client can have. The performance of this approach … …Journal of Computer Science, Vol. 8, Issue 7 · 8 Jun 2012 · 7,857 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordMammogram Analysis Based on Pixel Intensity Mean FeaturesR. Nithya, B. SanthiProblem statement: In the recent years, Computer Aided Diagnosis (CAD) can be very useful for detection of breast cancer. Mammography can be used as an efficient tool for breast cancer diagnosis. A computer based diagnosis and classification system can reduce unnecessary biopsy. Approach: This study investigates a new approach to the classification of mammogram images based on pixel intensity mean … …Journal of Computer Science, Vol. 8, Issue 3 · 7 Jan 2012 · 7,666 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordA Review on Recent Research and Implementation Methodologies on Medical Image SegmentationS. K. Somasundaram, P. AlliProblem statement: Image segmentation plays a very important role in digital imaging applications for classifying the anatomical structures and other Regions of Interest. Segmentation refers to the process of identifying and isolating the surface and regions of the digital image which corresponds to the structural units.
