Flexural Behavior of Graphite Tailings RC Beams in Chloride Environment
Published 2023-01-01“…Through research, the main innovations and main findings of this paper are as follows: (1) In the three kinds of concrete experimental environment, the fracture load and ultimate load of concrete beams with graphite tailings replacement rate of 20% are the largest. (2) In the three kinds of concrete test environment, when the concrete test beams under the same load, with the increase of graphite tailings replacement rate, the mid-span deflection of concrete beams showed a trend of decreasing first and then increasing. …”

Unsupervised Quality Estimation Model for English to German Translation and Its Application in Extensive Supervised Evaluation
Published 2014-01-01“…Firstly, the designed incomprehensive factors result in language-bias problem, which means they perform well on some special language pairs but weak on other language pairs. Secondly, they tend to use no linguistic features or too many linguistic features, of which no usage of linguistic feature draws a lot of criticism from the linguists and too many linguistic features make the model weak in repeatability. …”

Dynamic flow control mechanism in large-scale streaming media multicast systems
Published 2010-01-01“…;SVGs dynamically remapped and classified packets according to QLI and flow status information feedback from RVG,and reassigned each QoS level flow rates based on their utilities.Once the QoS of receivers could not be satisfied(i.e.,average delay and loss rate exceed the tolerable range),RVG even requested to down-grade its level,and SVG would reduce the sending rate.In the end,simulation results demonstrate e2e-DFCM’s effectiveness.…”

Optimization method through topology reconfiguration for mobile underwater wireless sensor networks
Published 2015-06-01“…The topology of mobile underwater wireless sensor networks (MUWSN) evolves dynamically with ocean currents,which will have great impact on network performance.To solve this problem,a topology optimization method for MUWSNs is proposed based on topology reconfiguration.Firstly,the proposed method optimizes the coverage rate of MUWSNs by adjusting the location of sensor nodes through simulating fish behaviors.Secondly,to optimize the connectivity of MUWSNs,the proposed method repairs disconnected positions and eliminates key nodes in MUWSN through using redundant nodes.Finally,simulation results verify the rationality and validity of the proposed method.Experimental results show that the algorithm can guarantee the network coverage is maintained at about 97%,connectivity rate above 89%,with lower energy consumption.…”

Performance assessment approach based on change-point detection for network moving target defense
Published 2017-01-01“…A performance assessment approach based on change-point detection for network moving target defence was proposed.Directed to the problem of network resource graph not being able to present the effect of network resource vulnerabilities to network nodes,a conversion relationship between resource vulnerability changes and node security states was established by defining the concept of a hierarchical network resource graph and the efficiency of resource graph construction and updating were improved.Furthermore,directed to the problem of static detection algorithm not being able to precisely measure the dynamic change of network moving target defense,a change-point detection algorithm and standard degree measurement algorithm was designed.The security cost and benefit of network moving target defense in real-time and dynamically on the basis of unified metrics were defected and measured,which improved the evaluation accuracy.The analysis result of typical examples has proved the feasibility and the effectiveness of the proposed approach.…”
