| 1 | Study on fire extinguishing performance of ultrafine water mist in a cup burner显示文摘Two simplified models for predicting minimum extinguishing concentration(MEC) of ultrafine water mist(UFM)(<10 m) were developed based on limiting oxygen concentration(LOC) and combustion limit temperature(CLT),respectively.Experiment was conducted using a modified cup burner which can reduce the surface adsorption of UFM.Two typical liquid fuels,n-heptane and ethanol,were used in the experiment.Tests using the same scenario were repeated 20 times or 10 times according to the variance of extinguishing time.The average and the standard deviations of extinguishing time were used to evaluate the fire extinguishing performance of UFM.Experimental results agree well with the model based on LOC,and disagree with the model based on CLT.The disagreements were explained by analyzing flow behavior of UFM.It was concluded that the primary mechanism of fire extinguishment with UFM was oxygen dilution. | LIANG TianShui LIAO GuangXuan LU SiuMing WANG XiShi | 2012 | Science China(Technological Sciences)2012，55，7： | 2 |
| 2 | Privacy-preserving edge-assisted image retrieval and classification in IoT显示文摘Internet of Things (IoT) has drawn much attention in recent years. However, the image data captured by IoT terminal devices are closely related to users, personal information, which are sensitive and should be protected. Though traditional privacy-preserving outsourced computing solutions such as homomorphic cryptographic primitives can support privacy-preserving computing, they consume a significant amount of computation and storage resources. Thus, it becomes a heavy burden on IoT terminal devices with limited resources. In order to reduce the resource consumption of terminal device, we propose an edge-assisted privacy-preserving outsourced computing framework for image processing, including image retrieval and classification. The edge nodes cooperate with the terminal device to protect data and support privacy-preserving computing on the semitrusted cloud server. Under this framework, edge-assisted privacy-preserving image retrieval and classification schemes are proposed in this paper. The security analysis and performance evaluation show that the proposed schemes greatly reduce the computational, communication and storage burden of IoT terminal device while ensuring image data security. | Xuan LI Jin LI Siuming YIU Chongzhi GAO Jinbo XIONG | 2019 | Frontiers of Computer Science2019，13，5： | 2 |

| 11 | Correlation of rate of gas temperature rise with mass loss rate in a ceiling vented compartment显示文摘n-heptane pool fire and industrial alcohol pool fire in a ceiling vented compartment were studied experimentally. The parameters including mass loss rate and rate of gas temperature rise were investigated. The results suggest that the rate of gas temperature rise, whose variations were highly coincident with those of the mass loss rate, minimized at the moment of extinction. The correlation of the rate of average nondimensional temperature rise with mass loss rate was established. It was found that the rate of average nondimensional temperature rise may be correlated with mass loss rate via the gas heat absorption coefficient which was found to be a quadratic function of the nondimensional heat release rate for the ceiling vented compartment under study. The present study may be of practical use for estimation of the time-dependent changes in mass loss rate from the gas temperature curves. | Ruiyu Chen Shouxiang Lu Bosi Zhang Changhai Li Siuming Lo | 2014 | Chinese Science Bulletin2014，59，33： | 0 |
| 12 | Observations of Passenger Flow and Verification of a Crowd Dynamics Model显示文摘This paper reports observations of passenger flow in the Wuchang railway station in Wuhan,China during the Chinese Traditional Spring Festival in 2006.The data collected are used to verify a crowd dynamics model previously developed.The crowd dynamics model is based on simulating the global movement of each individual under the influence of the surrounding crowd,and the good agreement between the predictions and observations validates the prediction model.The crowd dynamics model suggests that the crowd movement speed is dominated by two factors: the front-back inter-person effect,and the pedestrian’s self-motive.The first effect gives logarithmic relationship between the crowd speed and crowd density.The second factor depends on the individual motive driven with which people try to divorce themselves from the control of the crowd movement.The prediction model are helpful to guide the design of public traffic systems for effective crowd dispersal. | YUAN Jianping FANG Zheng LO Siuming XIE Lilin HUANG Danguang | 2008 | Wuhan University Journal of Natural Sciences2008，13，2： | 0 |
| 13 | Server-Aided Multi-Secret Sharing Scheme for Weak Computational Devices显示文摘In the setting of(t,n)threshold secret sharing,at least t parties can reconstruct the secret,and fewer than t parties learn nothing about the secret.However,to achieve fairness,the existing secret sharing schemes either assume a trusted party exists or require running multi-round,which is not practical in a real application.In addition,the cost of verification grows dramatically with the number of participants and the communication complexity is O(t),if there is not a trusted combiner in the reconstruction phase.In this work,we propose a fair server-aided multi-secret sharing scheme for weak computational devices.The malicious behavior of clients or server providers in the scheme can be verified,and the server provider learns nothing about the secret shadows and the secrets.Unlike other secret sharing schemes,our scheme does not require interaction among users and can work in asynchronous mode,which is suitable for mobile networks or cloud computing environments since weak computational mobile devices are not always online.Moreover,in the scheme,the secret shadow is reusable,and expensive computation such as reconstruction computation and homomorphic verification computation can be outsourced to the server provider,and the users only require a small amount of computation. | En Zhang Xintao Duan Siuming Yiu Junbin Fang Zoe L.Jiang Tsz HonYuen Jie Peng | 2018 | Computers, Materials & Continua2018，，9： | 0 |
