We present an indicator matrix representation for differential encoded signals and the optimal HMM filter for demodulation. The filter requires O(N/sup 3/) calculations per time iteration, where N is the number of message symbols. Decision feedback equalisation is investigated via coupling the optimal HMM filter for estimating the message, conditioned on estimates of the channel parameters, and a KF for estimating the channel states, conditioned on soft information message estimates. The particular differential encoding scheme examined in this paper is differential phase shift keying. However, the techniques developed can be extended to other forms of differential modulation. The channel model we use allows for multiplicative channel distortions and additive white Gaussian noise. Simulation studies are also presented.","PeriodicalId":394492,"journal":{"name":"1998 Second International Conference. Knowledge-Based Intelligent Electronic Systems. Proceedings KES'98 (Cat.

We assume that there is coordination among the followers while between the leader and the group of all the followers, there is no motivation to cooperate each other, and fuzzy goals for objective functions of the leader and followers are introduced in order to take fuzziness of their judgments into consideration. The leader maximizes the degree of satisfaction and the followers choose in concert so as to maximize a minimum among their degrees of satisfaction. A computational method, which is based on the genetic algorithms, for obtaining a solution to the above mentioned problem is developed.

Fusion of evaluation of possibility production function and DEA by introducing a fuzzy goal 引入模糊目标，实现可能性生产函数评价与DEA的融合

Efficiency evaluation based on the production function is considered. Loglinear production function (Cobb-Douglas model) has been used. This loglinear model evaluates DMU by measuring the average. DEA (data envelopment analysis) is also suitable, as for example in CCR (Charnes-Cooper-Rhodes) and BCC (Banker-Charnes-Cooper) model, but it does not give the lower limit of the production set, only the upper one. We propose the possibility production function by introducing fuzziness into the loglinear production function. As we try to evaluate the efficiency by this possibility production function, efficiency ratings are obtained for the upper and lower limits. Though DEA and fuzzy loglinear model belong to the evaluating method in the sense of including all DMUs' data, DEA obtains lower limit inputs by the present output, and fuzzy loglinear approach obtains the possibility max output by the present inputs. Making full use of the difference of the two approaches, we try to fuse them by introducing the concept of a fuzzy goal. We propose to construct a fuzzy goal by the evaluating ratings for individual outputs by fuzzy loglinear analysis, and introduce this fuzzy goal into DEA. At all, by this fusion we can cover the important weak point in DEA which often evaluates one output and ignores the other outputs, and we can obtain the satisfactory evaluation ratings which considers possibility outputs from the present inputs.","PeriodicalId":394492,"journal":{"name":"1998 Second International Conference.

Discussions on networks, e.g., by a mailing list, Usenet newsgroup, or online forum, are becoming more and more popular. However, many people have difficulty following and participating in discussions on networks, and one of the reasons is due to a failure to grasp the context of discussions. Previous tools have been insufficient in helping to avoid this failure. In order to solve this problem, we have developed CommunityBoard. Users can avoid confusion and achieve informative discussion. This system provides one integrated view of discussions from three aspects: the speakers, topics and time. The integrated view enables users to easily obtain various information about these aspects at one glance and this leads to lively and productive discussions. An example illustrates the efficiency of CommunityBoard.","PeriodicalId":394492,"journal":{"name":"1998 Second International Conference. Knowledge-Based Intelligent Electronic Systems.

The parameters of the transformation matrix-expansion, rotation, and translation-are derived by comparing successive images, and progressively increasing the image time separation. The increased baseline results in a triangulation accuracy which is much improved compared to that currently achievable.
