This paper mainly studies the data communication protocols of control area network (CAN) for the vehicle information systems. The objective is to create the environment of the line replaceable unit (LRU) in these systems. The data transmitted from CANBus are one of the valuable resources. There are 8 bytes of them in each transmission. If they are appropriately planned, the data communication protocol can improve the efficiency of the communication, e.g., arbitrations, masks, filters of nodes for CAN can be assigned arbitrarily on line. Even the software of CAN unit can be upgraded and downloaded on line, too. Upon the above concept, this paper will propose a feasible configuration of the vehicle information systems as well as a kind of possible data communication protocols. [ABSTRACT FROM AUTHOR]

RSS is a one of the most important techniques in Web 2.0. Although there are a lot of RSS feeds available, finding which information are relevant to user isn't easy. The previous RSS search services have not taken into account RSS feed characteristics and user's contextual information. This seriously limits to offer users with useful information. This paper proposes a new personalized RSS search service using the RSS feed structure and user's context. The proposed method collects the data from RSS service site by categorizing RSS feed structure and then rank RSS channel using RSS tag characteristics and user's context. The system architecture and the search algorithms are described. We design a RSS feed crawler, RSS feed repository and a RSS feed search engine. [ABSTRACT FROM AUTHOR]

Along with enterprise alliance that strides the district, strides the trade and strides nation recombining, there needs a public technical service platform urgently in order to ensure the alliance resources shared effectively. It also should response the changes of market fast. The emergence of grid technology provides a good way to solve this kind of problems. This paper set forth procreant reason, characteristic, system structure and work flow of dynamic alliance on grid in order to realize share of computing resource, storage resource, dada resource, information resource, software resource, network resource, communication resource, knowledge resource, expert resource, and to eliminate information independence and resource independence, then realize high capability structure sharing and cooperating in network virtual environment.
