Interactive media server with media synchronized raid storage system

We propose an efficient placement algorithm and per-disk prefetching method to effectively support interactive operations in the media server. Our placement policy is incorporated with an encoder having a special bitcount control scheme that repeatedly tunes quantization parameters to adjust the bitcounts of video frames. This encoder can generate coded frames whose sizes are synchronized with the RAID stripe size, so that when various fast-forward levels are accessed we can reduce the seek and rotational latency and enhance the disk throughput of each disk in the RAID system. In the experimental results, the proposed placement policy and bitrate control scheme can significantly improve the average service time, which can enlarge the capacity of the interactive media server

Peace building : Operational imperatives and organizational co-dordenation

This paper examines how various components of peace building programmes in different sectors can be co-ordinated. It starts with the examination of the practice by various co-ordinating mechanisms applied to post-conflict peace building operations. By using the example of Bosnia, the paper examines various features of vertical and lateral co-ordination and discusses how NGO operations can support major international agencies in converting their strategic level decisions into field operations
