在资料整编中,采用传统方法获得稳定的水位流量关系曲线有一些缺点;而采用单一目标函数的优化模型拟合水位流量关系,又无法保证一次性获得符合假设检验的最优解。通过分析以往采用的幂指数型数学模型存在的问题,建立了加权有约束优化模型,将有约束问题转化为无约束问题,并采用粒子群算法求解,保证了求得的解为满足相关要求的全局最优解,解决了水位流量关系曲线模型参数的全自动率定问题。

对传统的波束域波束形成进行改进,提出一种改进的阵元域波束形成算法检测网络纠缠入侵信号。把传统的波束域旋转矢量的变换到阵元域中改善阵元域自适应算法的性能,利用纠缠入侵信号的特征值大于噪声的特征值这一性能,采用空间协方差矩阵逆的高阶次幂来逼近信号子空间,将求得权矢量投影于改进的阵元域的特征信号子空间。将求得权矢量投影于改进的阵元域的特征信号子空间,实现对网络纠缠入侵信号的检测。仿真实验表明,提出的改进的阵元域波束形成信号检测算法具有较好的自适应检测性能,计算量和信号检测稳健性有明显改善,在网络入侵检测中具有较好的工程实用价值。

The investigation and continuous monitoring with an innovative iron oxide embedded cellulose acetate membrane (FeO/CAM) on the concentrations of biologically available phosphorus (BAP) were conducted in the Meiliang Bay of the Taihu Lake during summer in 2004. The results showed that the concentrations of dissolved (FeO-DP), particulate (FeO-PP) and total bioavailable phosphorus (FeO-P) had similar horizontal distribution. The BAP concentrations were the highest in those estuaries in the northern bay. With the decrease of the distance to the estuary or long shore,there was little difference between BAP concentrations in an open lake area. During the observation period, algal blooms occurred in most waters of the northern bay, which was reflected from the high concentrations of chlorophyll a (Chl-a). While they were not highest in the estuarine waters of those major rivers, this is the case for the BAP concentrations. The concentrations of Chl-a had a significantly positive correlation with those of bioavailable phosphorus in the open area of the Meiliang *** the sediment resuspension induced by wind and wave, BAP concentrations increased in a short-term, indicating that the riverine P inputs mainly contribute to the concentrations of BAP in the estuarine water while internal P release was the major source of BAP in the open lake area. In the eutrophic shallow lake, the blooms of alga may cause pH increase and further result in internal P release. The above results showed that the new membrane of FeO/CAM can be used to monitor the concentrations of BAP and provide the scientific justifications for the control strategy of the lake eutrophication.

对于无线多跳网络,基于网络搅拌的拓扑干预机制可实现分布式可调的高能效无线拓扑,然而传统的拓扑干预机制没有解决底层节点与边搅拌子机制之间的平衡问题。提出了一种平衡的能耗优化拓扑干预算法,该算法首先使用多层序列规划法将一般的非线性优化问题转换为边搅拌和节点搅拌子机制的独立优化子问题,然后利用这些问题的解分析网络中的能量消耗与平均路径长度之间潜在的平衡性能。通过在不同网络规模和操作需求下的仿真,验证了该算法的有效性和适用性,并发现了在能耗约束与吞吐量约束的网络中,节点搅拌机制与边搅拌机制的平衡点。
