We propose and design a peer-to-peer system, SeCond, addressing the distribution of large sized content to a large number of end systems in an efficient manner. In contrast to prior work, it employs a self-organizing epidemic dissemination scheme for state propagation of available blocks and initiation of block transmissions. In order to exploit(More)
We propose an efficient cooperative content distribution protocol in which the cooperation among participants is based on a peer-to-peer (P2P) paradigm. Our main contribution to P2P content distribution is the use of an epidemic communication approach. Since epidemic algorithms are easy to use, robust and adaptive to dynamic conditions, they have found(More)
Structural variations of SiOx matrix have been studied with Fourier Transform Infrared Spectroscopy (FTIR) during the formation of Si and Ge nanocrystal. Two frequently used methods, magnetron sputtering and ion implantation have been employed to form SiOx matrix containing excess Si and Ge. The Si-O-Si stretching mode has been deconvoluted to monitor the(More)
BACKGROUND Small cell lung cancer (SCLC) commonly presents as hilar/mediastinal masses. In some occasions, conventional flexible bronchoscopy fails and a substantial amount of time is lost until establishing the diagnosis. OBJECTIVE The aim of the study was to demonstrate the superiority of endobronchial ultrasound-guided transbronchial needle aspiration(More)
