Cooperative access systems
In the next five years we can expect to find a variety of cooperative natural language (NL) interfaces to database systems, expert systems, operating systems, CAD systems and even text formatting systems. Although the general problem of getting computers to understand NL is far from being solved, the technology for limited NL access systems is available now and there is a large growing market f...
متن کاملAccess Controls for Cooperative Environments
With security issues increasingly gaining importance, cooperative environments and especially workflow systems have to incorporate techniques dealing with this problem. Existing concepts have, with very few exceptions [1], so far been focused on operating and database systems and little effort has been seen as far as workflow reference models are concerned. That is why this paper tries to evalu...
متن کاملCooperation Scenarios in Cooperative Multiple Access Channels
In this paper, we present preliminary results on achievables rates in half-duplex cooperative multiple access channels (CMAC). We show that the upper bound on the capacity of the half-duplex CMAC can be solved using convex optimization techniques. Under a Gaussian model, we study the maximal achievable rate by every node in the network. We propose a number of scenarios, encompassing existing an...
متن کاملCooperative Internet Access in Resource Constrained Environments
Access to the Internet has become available at virtually any place in developed and developing countries, either by fixed-line or wireless access. The Internet users are used to check emails, read web pages, or see a video at any time via the Internet and are annoyed if the access does not work or does work but too slowly for the used application. The access to the Internet is stable and fast e...
