To represent and reason with interval-value information of applications in description logic, based on interval-fuzzy set the classical description logic *** is extended to the fuzzy description logic IFALCN. Its' syntax, semantics and fuzzy tableau algorithm are presented in detail. Our work enhances the expressiveness and reasoning ability of ALCN. IFALCN is the generalization of fuzzy ALCN based on single value and more expressive than the latter and can conform to human cognition better.
Focusing on the inversing operation of cardinal directions, the current generative method does not always work correctly. According to the given definitions of smallest rectangular direction and original directions, t...

Because of restricted energy of the sensor nodes, the location error, costs of communication and computation should be considered in localization algorithms. The DV-Hop algorithm was detailedly analyzed and the main reasons for the error were pointed out, aiming at the different position anchor nodes' effect on location error, a novel localization algorithm called DV-Hop_Bon (DV-Hop based on optimal nodes) based on optimal nodes was put forward. Finally, it was simulated on Matlab, the results of the simulation show that the novel localization algorithm improves the localization precision with a short communication radius. Therefore it can be applied to wireless sensor networks widely.

The major problem in developing a useful formalism for reasoning about spatial information is the trade off between expressive power and computational tractability. Based on Bennett's modal representation of convex-hull and the RCC62 model which describes the topological relation between simple concave regions, the modal representation of RCC62 is presented in this paper, which has a theoretical advantage over 1st-order representations.
In order to realize that IPv6 (Internet Protocol version 6) clients are able to visit remote IPv6 servers through GPRS (General Packet Radio Service), we proposed a new and feasible framework. After discussing the lim...
