The capacity of the multiple-access channel with any distribution of messages among the transmitting nodes was determined by Han in 1979 and the expression of the capacity region contains a number of rate bounds and that grows exponentially with the number of messages. We derive a more compact expression for the capacity region of this channel in which the number of rate bounds depends on the d...

Surveillance video is characterized by short periods of activity in a small region of the image, and long periods of inactivity. When transmitting such video sequences over a wireless network, it is important to dynamically adapt the encoding of each stream according to both the video content and the underlying network conditions. We propose a video surveillance system that exploits H.264/AVC c...

the structure and histogenesis of the stigma of datura stramonium was investigated by light and scanning electron microscopy to determine the developmental origin of the transmitting tissue and “wet stigma”. four developmental stages were defined on the basis of bud length. stage one, the histogenesis stage, was comprised of buds 2-15 mm in length. stage two, signified by the growth and develop...
