H6-inveter
提出一种新颖的高效率六开关逆变器(H6)拓扑，解决了无变压器单相光伏并网逆变器漏电流问题。 仿真与实验验证了该拓扑具有低共模电压、高质量的并网波形和高效率特征(This paper proposed a novel, high efficiency, transformerless single phase photovoltaic grid-connected inverter with six active switches that alleviate leakage current
issue. This topology embeds two unidirectional freewheel units
into the midpoint of a full bridge inverter, which provide novel freewheel paths and separate battery cells a grid during freewheeling time. )

High
This paper presents a clustering approach
which estimates the specific subspace and the intrinsic dimension of each class. Our approach
adapts the Gaussian mixture model framework to high-dimensional data and estimates
the parameters which best fit the data. We obtain a robust clustering method called High-
Dimensional Data Clustering (HDDC). We apply HDDC to locate objects in natural images
in a probabilistic framework. Experiments on a recently proposed database demonstrate the
effectiveness of our clustering method for category localization.

传感器网络
传感器网络由大量能量有限的微型传感器节点组成.因此,如何保证在足够覆盖监测区域的同时延长网络的寿命,是一个需要解决的重要问题.为了达到这一目标,一种广泛采用的策略是选出部分能够足够覆盖监测区域的节点作为工作节点,同时关闭其他冗余节点.提出了一个数学模型,使得只要已知监测范围和节点感知半径的比值,就可以计算出达到服务质量期望所需要的节点数量.需要指出的是:与大部分研究覆盖的文献不同,该研究不基于节点的位置信息,因此可以极大地降低硬件成本,并且减少节点获得和维护位置信息的开销.模拟实验结果表明:在随机部署条件下,服务质量期望与实验所得到的实际覆盖度的误差不大于服务质量期望的2％ 而对于相同的服务质量期望和实际覆盖度,计算所得的工作节点数量与实验所得的工作节点数量的误差小于计算数量的5％,这表明推导出的节点数量与服务质量期望之间的关系与模拟实验的结果相吻合.该结果可以广泛应用于传感器网络的节点部署、拓扑控制等领域中.()
