微波站路径电测标准值估算——利用60Hz测试仪表电测各工作频段的微波路径

在微波通信工程中，判别路径的通断是一项重要的勘察设计工作，常用的方法是利用1:5万的地形图，绘出两站的断面判断出路径是否满足要求。在障碍物阻挡明显时，该方法行之有效；但是，如果障碍物处于临界状态时，图上作业则无法精确判断出路径的通断，需要进行实地电测。

基于模糊修正的金融预测

文章研究了模糊逻辑模型在金融预测领域中的应用。由于该模型自身的局限性,在对金融时间序列趋势的连续预测应用中,趋势准确率偏低,连续预测值波动小(体现不出未来的市场走向),对此,提出了模糊修正的方法。文章运用模糊修正模型对上证综合指数和道琼斯平均工业指数做试验,并与BP神经网络进行比较,试验结果表明,运用模糊修正模型进行金融预测是可行的和有效的。

环形互连并行系统上的任务分配

This paper is about distributed processing of a divisible task in a ring of communicating processors,all works are based on ring topology.Out distribution scheme aims to guarantee minimal finish time of the whole task,which is divided into parts (subtasks)and scheduled to the individual processors.In our model the communication startup time and delay time are both taken into consideration;we also discuss the cases of returning results or not as well as sending data in prallel or not,and returning results through the ring are our focus for discussion.The volume of subtask assigned to each processor is gotten after creating and solving the linear equations.At last the empirical results are presented.     

求解圆形packing问题的拟人退火算法

Circles packing problem is an NP-hard problem and is difficult to solve. In this paper, a hybrid search strategy for circles packing problem is discussed. A way of generating new configuration is presented by simulating the moving of elastic objects, which can avoid the blindness of simulated annealing search and make iteration process converge fast. Inspired by the life experiences of people, an effective personified strategy to jump out of local minima is given. Based on the simulated annealing idea and personification strategy, an effective personified annealing algorithm for circles packing problem is developed. Numerical experiments on benchmark problem instances show that the proposed algorithm outperforms the best algorithm in the literature.
