| 1 | Minimizing transmission loss using inspired ant colony optimization and Markov Chain Monte Carlo in underwater WSN environment显示文摘In Underwater Wireless Sensor Networks(UWSNs),the most important challenging issues are propagation delay,high error probability,high latency,high communication cost,limited bandwidth,limited memory,low packet delivery ratio,and transmission loss.In our proposed work,the various efforts are taken to minimize the propagation delay and transmission loss during data transmission in an underwater environment.A hybrid mechanism is implemented to improve energy efficiency for faster data transmission in underwater WSN.In the underwater environment of acoustic channel condition,propagation delay and transmission loss lead to high complexity in accessing the information and also it is difficult to obtain the Channel Status Information(CSI).To address this problem,Ant Colony Optimization(ACO)routing with Markov Chain Monte Carlo(MCMC)algorithm is used and to capture the transmission loss in the MCMC approach,CSI Forecast Prediction(FP)algorithm is used.The experimental simulations are evaluated by utilizing the performance evaluation metrics such as Transmission Loss,Probability Density Function,Average Delay and Throughput.From the simulation results it is evident that the proposed algorithm,ACO-MCMC has recorded the minimum transmission loss,increase in probability density function,minimum average delay and maximum throughput of the network when compared to the existing algorithms. | Raj Priyadarshini R Sivakumar N | 2019 | Journal of Ocean Engineering and Science2019，4，4： | 7 |

| 3 | Mosquito larvicidal properties of Ficus henghalensis L.(Family:Moraceae) against Culex tritaeniorhynchus Giles and Anopheles subpictus Grassi(Diptera:Culicidae)显示文摘Objective:To determine the larvicidal efficacy of different solvent leaf extract of Ficus benghalensis(F.benghalensis) against Culex tritaeniorhynchus(Cx.tritaeniorhynchus) and Anopheles subpictus(An.subpictus).Methods:Twenty five early third instar larvae of Cx. tritaeniorhynchus and An.subpictus were exposed to various concentrations and were assayed in the laboratory by using the protocol of WHO 2005.The larval mortality was observed after 24 h of treatment.Results:Among three solvent extracts tested the maximum efficacy was observed in the methanol extract.The LC50 and LC90 values of F.benghalensis against early third instar of Cx. tritaeniorhynchus and An.subpictus were 100.88.159.76 ppm and 56.66.85.84 ppm.respectively. No mortality was observed in controls.The chi-square values were significant at P<0.05 level. Conclusions:From the results it can be concluded the crude extract of F.benghalensis was an excellent potential for controlling Cx.tritaeniorhynchus and Art.subpictus mosquito larvae. | M Govindarajan R Sivakumar A Amsath S Niraimathi | 2011 | Asian Pacific Journal of Tropical Medicine2011，4，7： | 3 |
| 4 | 焊接参数对搅拌摩擦焊接AA2219-T87材料韧性、洋葱圆环的断裂行为的影响(英文)显示文摘与熔焊相比,搅拌摩擦焊可以更好地保持材料的韧性和塑性,提高焊接的抗裂稳定性。本研究旨在提高焊接接头的延性和强度。刀具廓形在保持延性、分析金属流动行为和确定断裂起始点等方面起着重要作用。分析了洋葱圆环不同区域的微观结构,得出了洋葱圆环强度与金属流型的关系。结果表明,洋葱圆环强化了焊缝熔核。肩部和锥形螺纹型线刀具具有优异的力学性能。显微硬度数据表明,断口经过热影响区和热机械影响区等低硬度区。扫描电镜图像显示了细长的晶粒和韧窝,证实了断裂为韧性断裂。 | Dinesh KUMAR R S MUTHUKUMARAN Vincent XAVIER T VENKATESWARAN D SIVAKUMAR | 2019 | Journal of Central South University2019，26，9： | 2 |
