An energy efficient routing algorithm is the major concern in wireless sensor networks(WSNs),especial-ly the hot spot,because of unbalanced energy consumption. Based on uneven clustering and entropy theory,a kindof improved routing algorithm is proposed for solving that problem. In the process of cluster head election and com-petition radius calculation,node energy,density and distance to BS are considered to effectively balance energy con-sumption and prolong the life cycle of cluster head nodes. Meanwhile the hybrid rules of single-hop and multi-hoprouting is adopted to reduce the energy consumption among clusters. Introducing fusion weight coefficient,informa-tion entropy mechanism is used for reducing the uncertainty and improving the efficiency of data fusion. Simulationresults show that compared with LEACH,EEUC and EBUCA,the new algorithm can balance energy consumptionand prolong the life cycle of wireless sensor networks.

The plunging jet is a phenomenon of two phase gas-liquid flow, which could be an effective method to sufficiently mix boric acid with de-ionized water, and is suitable for studying the Pressurized Thermal Shock (PTS) accident scenario of Pressurized Water Reactors(PWR). The air is entrained when the liquid jet hits the water surface, which generates bubbles during the air entrainment. This bubble entrainment has a crucial influence on the mixing process. The distribution of void fraction was studied in dependence of the jet length and flow rate. A movable three-layer Wire Mesh Sensor (WMS) is designed to measure sequences of instantaneous two-dimensional gas fractions with a high-resolution in space and time, which, from the data, derives the void fraction distributions. Comparisons of average void fraction are carried out with different jet lengths and flow rates.

As a typical resource constrained system,Wireless Sensor Network (WSN) can be significantly improved the performance of guarantee quality of service (QoS) by effective resource allocation,including channel and time slot. But the structure is not fixed in smart medical system,which can lead to the uncertainty service quality. A non-balanced cluster tree structure is present for overcoming the collision and uncertain delay,taking into account the allocation of traffic. The resource parameter is implemented in TinyOS system,which be verified by CC2530 platform. And Graphical User Interface is designed for modifying data flow parameters and inspecting scheduling results. The experimental results show that this cluster tree scheduling algorithm can ensure the non-balanced structure of network quality,and provide the effective service guarantee for large-scale cluster tree network.

In order to maximize lifetime of Wireless Sensor Networks( WSNs),a balanced rate area coverage algorithm( BRACA) is presented,which aims at the problem of energy uniformity and balanced coverage. This algorithm introduces the idea of balanced coverage rate. And it considers the sensors' balance about target area coverage rate and the residual energy as filtering factors. By adjusting the ratio of sensor's residual energy to its average coverage rate,we can find a sensor subset with maximum uncorrelation and minimum cost,which achieves area coverage using nodes as few as possible. Experimental results show that BRACA has better computational efficiency. The e-coverage sensor subset can prolong network lifetime effectively due to consuming the less and balanced energy in the premise of ensuring the network coverage of no less than 90% in the WSNs.

A novel scheme for mass segmentation in mammography is proposed,which is based on Graph Cuts algorithm and multi-scale analysis.Mammogram is segmented by statistical region merging firstly,and the obtained rough contour is used as the initial contour for Graph Cuts segmentation.In iterative optimization stage of the algorithm,multi-scale analysis method is introduced to estimate the Gaussian Mixture Model(GMM)parameters with pyramidal decomposing serial images instead of fix-scale original image.The algorithm estimates GMM parameters rapidly with fewer samples by utilizing the complementarities between segmentation accuracy of fine scale and segmentation easiness of coarse scale.In order to improve efficiency of the proposed approach,watershed algorithm is utilized to produce a region adjacency graph,replacing pixel adjacency graph with fewer samples.The proposed method,interactive Graph Cuts and GrabCut were simultaneously applied for mass segmentation on 110 mammographic ROIs,and the achieved average ratios of misclassification error are 1.57,3.46 and 5.01 respectively.The results demonstrate that the proposed method achieves a better performance in accuracy and robustness.
