The use of tin and bronze in prehistoric southern Indian metallurgy

The medieval icons of southern India are among the most acclaimed Indian artistic innovations, especially those of the Chola Tamil kingdom (9th–10th centuries), which is best known for the Hindu iconography of the Dance of Siva that captured the imagination of master sculptor Rodin.1 Apart from these prolific images, however, not much was known about southern Indian copperbased metallurgy. Hence, these often spectacular castings have been regarded as a sudden efflorescence, almost without precedent, of skilled metallurgy as contrasted with tin-rich China or southeast Asia, for instance, where a developed copper-bronze tradition has been better appreciated.

On the Implementation of a Streaming Video over Peer to Peer network using Middleware Components

Video streaming applications have hitherto been supported by single server systems. A major drawback of such a solution is that it increases the server load. The server restricts the number of clients that can be simultaneously supported due to limitation in bandwidth. The constraints of a single server system can be overcome in video streaming if we exploit the endless resources available in a distributed and networked system. We explore a P2P system for streaming video applications. In this paper we build a P2P streaming video (SVP2P) service in which multiple peers co-operate to serve video segments for new requests, thereby reducing server load and bandwidth used. Our simulation shows the playback latency using SVP2P is roughly 1/4th of the latency incurred when the server directly streams the video. Bandwidth consumed for control messages (overhead) is as low as 1.5% of the total data transfered. The most important observation is that the capacity of the SVP2P grows dynamically.
