Thin structures such as fence, grass and vessels are common in photography and scientific imaging. They exhibit complex 3D structures with sharp depth variations/discontinuities and mutual occlusions. In this paper, we develop a method to estimate the occlusion matte and depths of thin structures from a focal image stack, which is obtained either by varying the focus/aperture of the lens or computed...
There is no method to evaluate the status of laminar flow and single-cell flow directly in the flow cell of flow cytometer, in order to solve the problem, a method of high-speed particle image velocimetry based on the side Mie scattering is proposed. The velocity stability of the particles in the flow cell is used to represent the flow stability of the flow cytometer fluid path. Firstly, side Mie...
In this paper, we propose a scalable clustering paradigm to address the problems of excessive computational load and limited clustering performance in large-scale data. The proposed method employs the enhanced splitting merging awareness tactics (E-SMART) algorithm. The large-scale dataset is divided into many sub-datasets sampled randomly from original data. These sub-datasets are clustered using...
A static dial-a-ride problem with time windows is investigated, without wait while carrying passengers and maximum ride time constraints as the service quality. A parallel insertion heuristic based on the spatial and temporal aspects is presented. The proposed algorithm firstly sorts the requests based on the earliest pickup time and decentralization index alternately and initializes the routes with...
To reduce the cost and risk of the development of system of systems (SoS) by pre-evaluation before the SoS is built, a model-driven approach is proposed to evaluate the SoS based on its architecture, especially focused on measures of performance and effectiveness. In order to implement the pre-evaluation, the system architecture needs to be transformed to the simulation model of the system under the...
Post knowledge push is a significant topic in enterprise's knowledge management. How to evaluate post knowledge push effect is an important problem. In this paper, first, the comprehensive evaluation vector of satisfaction can be determined by integrating all post employees' evaluation vector of satisfaction concerning evaluation index. Then, based on the evaluation vector of index importance and...
In order to solve the problem that enterprise-level users mass data storage and high-speed data processing services growth, and the traditional storage system can not meet the data services business growth, enterprise file cloud storage system is proposed. It is based on Hadoop, uses Linux cluster technology, distributed file systems and cloud computing framework, provides large-scale data storage...
The intensive and fast development of livestock farming with ecological pattern of raising-biogas-irrigating is widely applied in China. After anaerobic fermentation the agricultural wastes can provides clean energy. However, there is problem by lacking of land to digest the biogas slurry. Based on livestock wastewater from a dairy farming, the experiment used modified two-stage anoxic/oxic (A/O)...
The variations of Baltic Dry Index (BDI) and Shanghai Stock Exchange Composite Index (SSE Composite Index) over the last three years reflected the historical features of the world economy in financial crisis. In order to test the correlation of BDI and SSE Composite Index, the weekly average data of BDI and SSE Composite Index from 2007 to 2009 are taken as empirical sample data by statistical analyzing...
Addressing the characteristics that the ArcGIS has relatively weak support to China's standard drawing of basic scale map form, and is unable to generate marking information automatically and repeatedly use the same decoration elements, this article adopts the Element under ArcEngine components to implement the map decoration with1:50 000 plotting scale. The system can draw out the decoration contents...
Mesh-based peer-to-peer (P2P) streaming has proven to be a robust and scalable way for delivering live video streams over the Internet. In this paper, we study how to optimize overlay in a contribution aware manner. We have designed a suite of protocols to construct and optimize the overlay. Our core idea is to promote nodes with larger contribution closer to the source node so as to keep a compact...
This research investigated the distribution of eutrophication degree in Nansi Lake using remote sensing data. Nine sampling points were monitored with Chla, TP and TN three parameters in upper lake of Nansi Lake. TSI of each sampling points was calculated using Carlsonpsilas TSIM. Then the linear model between remote sensing data and TSIM of each field monitoring points in upper lake of Nansi Lake...
In this paper, we study how to optimize mesh-based overlay in a contribution aware manner. We have designed a suite of protocols to construct and optimize the overlay. Our core idea is to promote nodes with larger contribution closer to the source node so as to keep a compact and efficient mesh-based streaming overlay. Our method is evaluated through extensive simulations. Compared with the non-optimized...
