To realize the highest performance possible for a sequential processor, and to realize utilization of a large amount of existing software, an integrated Prolog processor (IPP) and its optimized compiler are now being developed. A tagged architecture under constraints of a general purpose computer and a memory management strategy to achieve a high(More)
This paper proposes several new schemes which allow a sender to send encrypted messages to multiple recipients more efficiently (in terms of bandwidth and computation) than by using a standard encryption scheme. Most of the proposed schemes explore a new natural technique called randomness re-use. In order to analyze security of our constructions we(More)

For a TeV energy particle physics, R&D of electron/positron linear colliders has been conducted very hard at many laboratories. Development of high field gradient cavities is one of key issues to realize such a machine. Field emission loading is a dominant phenomenon limiting high field. Particulate contamination on the inner surface is a main source of(More)
