Research on Response Decision Behavior of Construction Emergency Capacity Based on SD-SEM Model by WANG Jingwen

“…In order to study the impact of construction emergency capacity on emergency managers' response decision-making behavior,based on system dynamics model and structural equation model,this paper firstly conducts a questionnaire survey for the relevant personnel of the construction,then clarifies the path coefficients between the influencing factors of the construction emergency response capacity by processing the questionnaire survey data,finally establishes the system dynamics model to dynamically simulate the impact of the construction emergency response capacity on the rationality of response decision-making.The simulation results show that the emergency manager should report the danger within 2 hours after the accident,and start a coordinated emergency response plan with other project departments,which will help improve the on-site emergency response capacity,minimize casualties and economic losses,and enhance the rationality and accuracy of the response decision made by the emergency managers.…”

Optimal payload lengths of reliable multicast schemes by ZHU Feng1, WU Ling-shuang2, GU Yuan-tao1

“…Using total transmission time-the time needed to guarantee reliable data dissemination——as judgment criterion,the payload length selection problem was investigated for three multicast solutions which are based on simple feedback retransmission,Reed-Solomon codes,and LT fountain codes,respectively,with the consideration of packet overhead.A theoretical analysis method was proposed to determine the optimal payload lengths,which was verified by simulations.Analyses and simulations indicate,for variable packet overhead sizes and link bit error rates,each method considered has its optimal payload length.As link bit error rate increases,the performance gain brought by the selection of optimal pay-load lengths becomes more significant.Among the three solutions,the reliable multicast solution based on LT fountain codes has the most outstanding performance.…”

Modeling the Impact of Virtual Contact Network with Community Structure on the Epidemic Spreading by Jianlin Zhou, Haiyan Liu

“…We first use a microscopic Markov chain approach to characterize the coupled disease-awareness dynamics and then analyze the effect of different factors on the coevolution of information dissemination and epidemic spreading based on the Monte Carlo simulation. The simulation results show that promoting the dissemination of information is indeed conducive to suppressing the spread of disease, but changing the process of disease transmission has no obvious effect on the information dissemination. …”

Research on language recognition algorithm based on improved CFCC feature extraction by Hua LONG, Zhangheng HUANG, Yubin SHAO, Qingzhi DU, Shumeng SU

“…Aiming at the problem of low language recognition rate under low signal-to-noise ratio, a language recognition method based on fractional wavelet transform was proposed.Firstly, the adaptive filtering algorithm was used to filter the noise of the noisy signal, so as to reduce the influence of noise on the feature extraction and improve the processing ability of the system for non-stationary signals.Secondly, the motion of the signal on the basilar membrane of the cochlea was simulated, and then the signal was compressed by a nonlinear power function.Finally, the improved CFCC were extracted by simulating the human hearing process.Experiments show that compared with the traditional CFCC, the language recognition rate is significantly improved, and the language recognition rate is increased by 11.1% on average under the 0 dB signal-to-noise ratio, which verifies the effectiveness and robustness of the proposed algorithm.…”

Optimal transmission power selecting algorithm for cluster based ultra-wide bandwidth wireless sensor networks by PAN Gao-feng, FENG Quan-yuan

“…To solve the energy conservation and power control problem radically in the cluster based ultra wideband wireless sensor networks,an optimal transmission power selecting algorithm（OTPSA） was presented,the goal of which is,within the acceptable range of implementing cost,to get an optimal transmission power value based on the maximum transmission rate and the background noise level,as well as to achieve the required data transmission rate and to meet the energy conserving requirement to the greatest extent.The implementing feasibility,complexity and cost of the proposed algorithm have been analyzed and investigated in detail.The simulative results clearly show that the power consumed under OTPSA is greatly less than the maximum power gotten at each node,and can be regulated according to the fluctuation of the requirement of maximum rate and the background noise;sensor lifetime can also be prolonged by implementing the proposed scheme.Furthermore,the simulative results also indicate that the implementing cost of the presented algorithm is reasonable and acceptable.…”
