    Data/voicenideo integration on fiber distributed data interface
    (1990) Rudramuni, B.; Hegde, G.D.; Muthangi, S.P.; Paulraj, A.
    The Fiber Distributed Data Interface (FDDI) is a 100 megabit per second (Mbps) Local Area Network that uses Optical Fiber as the medium. It provides both the high bandwidth and low latency needed to match the capacity of future personal computers. Hence it is expected to become the preferred local area network systems of the 1990s. The FDDI protocol is based on a timed token ring access method. In this paper, we propose a media access control protocol for combined Data/Voice/Video services on FDDI. The most important service requirement for the packetized Voice and Video is the transport of this data with tolerable delays. Ile effect of multiple Voice and Video channels on the asynchronous data traffic and the capacity to handle these services on FDDI is investigated by means of simulation methods. � 1990 IEEE.

    The independent components of characters are 'strokes'
    (1999) Srinivasan, S.H.; Ramakrishnan, K.R.; Bhagavathy, S.
    What are the natural features of handwritten characters and how to arrive at them automatically? We apply independent components analysis on handwritten characters. Independent components analysis extracts the underlying statistically independent signals from a mixture of them. We expect strokes to be the independent components of handwritten characters. Our findings show that stroke-like features emerge as a result of the analysis confirming the above intuition. This finding is significant since it gives automatic procedures for extracting stroke-like features from multilingual character data sets. We use these features for handwritten digit recognition using a very simple classifier. The classifier is chosen to be simple so that the quality of the input feature set can be evaluated. The recognition results indicate that the features arrived at by independent component analysis are useful. � 1999 IEEE.
