| 1 | Membrane fouling in ultrafiltration of natural water after pretreatment to different extents显示文摘The combined fouling during ultrafiltration(UF) of surface water pretreated to different extents was investigated to disclose the roles of polysaccharides, proteins, and inorganic particles in UF membrane fouling. Both reversible and irreversible fouling decreased with enhanced pretreatment(biologically active carbon(BAC) treatment and sand filtration). The sand filter effluent fouled the membrane very slowly. The UF membrane removed turbidity to less than 0.1 nephelometric turbidity unit(NTU), reduced polysaccharides by 25.4%–29.9%, but rejected few proteins. Both polysaccharides and inorganic particles were detected on the fouled membranes, but inorganic particles could be effectively removed by backwashing. The increase of turbidity in the sand filter effluent to 3.05 NTU did not significantly increase the fouling rate, but an increase in the turbidity in the BAC effluent to6.11 NTU increased the fouling rate by more than 100%. The results demonstrated that the polysaccharide, not the protein, constituents of biopolymers were responsible for membrane fouling. Membrane fouling was closely associated with a small fraction of polysaccharides in the feed water. Inorganic particles exacerbated membrane fouling only when the concentration of fouling–inducing polysaccharides in the feed water was relatively high. The combined fouling was largely reversible, and polysaccharides were the predominant substances responsible for irreversible fouling. | Lu Ao Wenjun Liu Lin Zhao Xiaomao Wang | 2016 | Journal of Environmental Sciences2016，28，5： | 12 |

| 3 | High efficiency linear compressor driven pulse tube cryocooler operating in liquid nitrogen temperature显示文摘The inertance tube is one of the key components of a pulse tube cryocooler. It has great influence not only on the efficiency of the pulse tube cryocooler, but also on the efficiency of the linear compressor. Meanwhile, it is very difficult to predict the impedance of an inertance tube because of the turbulent flow. In this paper, using a quasi-turbulent model, the inertance tube is optimized to match a linear compressor driven pulse tube cryocooler. Experimental results show that this model can predict the impedance quite well. With 127 W input electric power, the pulse tube cryocooler obtains 9.4 W cooling power at a temperature of 77 K. The relative Carnot efficiency of the whole system reaches 19.8%. | HU JianYing WANG Xiaomao DAI Wei LUO ErCang HUANG Yu | 2009 | Chinese Science Bulletin2009，54，23： | 7 |
| 4 | Public Auditing for Encrypted Data with Client-Side Deduplication in Cloud Storage显示文摘Storage auditing and client-side deduplication techniques have been proposed to assure data integrity and improve storage efficiency, respectively. Recently, a few schemes start to consider these two different aspects together. However, these schemes either only support plaintext data file or have been proved insecure. In this paper, we propose a public auditing scheme for cloud storage systems, in which deduplication of encrypted data and data integrity checking can be achieved within the same framework. The cloud server can correctly check the ownership for new owners and the auditor can correctly check the integrity of deduplicated data. Our scheme supports deduplication of encrypted data by using the method of proxy re-encryption and also achieves deduplication of data tags by aggregating the tags from different owners. The analysis and experiment results show that our scheme is provably secure and efficient. | HE Kai HUANG Chuanhe ZHOU Hao SHI Jiaoli WANG Xiaomao DAN Feng | 2015 | Wuhan University Journal of Natural Sciences2015，20，4： | 4 |

| 6 | Development of a mobile powered hole digger for orchard tree cultivation using a slider-crank feed mechanism显示文摘The powered hole digger is one of the most important orchard machines.The power consumption of its drill is an important factor affecting the performance and operation of the device.The drill power consumption of the digger at a constant feed rate is directly proportional to digging depth.This research discusses a newly designed powered hole digger using a slider-crank feed mechanism.The motion characteristics of the powered hole digger feeding mechanism was analysed.Additionally,an experiment was conducted to determine the characteristics of the drill power consumption.It can be concluded that there was a positive correlation between the drill power consumption and the powered hole digger feed rate.It was observed that when digging depth reached 200 mm,the drill power consumption reached the maximum power rating;subsequently the drill power consumption decreased with an increase of digging depth.When the drill reached the bottom of the hole,the power consumption of the new powered hole digger did not exceed the maximum designed power rating,hence the drill motor would not stall. | Zong Wangyuan Wang Jingliang Huang Xiaomao Yu Dong Zhao Yingbiao Sean Graham | 2016 | International Journal of Agricultural and Biological Engineering2016，9，3： | 3 |
| 7 | Using loose nanofiltration membrane for lake water treatment:A pilot study显示文摘Nanofiltration(NF)using loose membranes has a high application potential for advanced treatment of drinking water by selectively removing contaminants from the water,while membrane fouling remains one of the biggest problems of the process.This paper reported a seven-month pilot study of using a loose NF membrane to treat a sand filtration effluent which had a relatively high turbidity(∼0.4 NTU)and high concentrations of organic matter(up to 5 mg/L as TOC),hardness and sulfate.Results showed that the membrane demonstrated a high rejection of TOC(by<90%)and a moderately high rejection of two pesticides(54%–82%)while a moderate rejection of both calcium and magnesium(∼45%)and a low rejection of total dissolved solids(∼27%).The membrane elements suffered from severe membrane fouling,with the membrane permeance decreased by 70%after 85 days operation.The membrane fouling was dominated by organic fouling,while biological fouling was moderate.Inorganic fouling was mainly caused by deposition of aluminum-bearing substances.Though inorganic foulants were minor contents on membrane,their contribution to overall membrane fouling was substantial.Membrane fouling was not uniform on membrane.While contents of organic and inorganic foulants were the highest at the inlet and outlet region,respectively,the severity of membrane fouling increased from the inlet to the outlet region of membrane element with a difference higher than 30%.While alkaline cleaning was not effective in removing the membrane foulants,the use of ethylenediamine tetraacetate(EDTA)at alkaline conditions could effectively restore the membrane permeance. | Danyang Liu Johny Cabrera Lijuan Zhong Wenjing Wang Dingyuan Duan Xiaomao Wang Shuming Liu Yuefeng F.Xie | 2021 | Frontiers of Environmental Science & Engineering2021，15，4： | 3 |

| 12 | Techno-economic characteristics of wastewater treatment plants retrofitted from the conventional activated sludge process to the membrane bioreactor process显示文摘While a growing number of wastewater treatment plants(WWTPs)are being retrofitted from the conventional activated sludge(CAS)process to the membrane bioreactor(MBR)process,the debate on the techno-economy of MBR vs.CAS has continued and calls for a thorough assessment based on techno-economic valuation.In this study,we analyzed the operating data of 20 large-scale WWTPs(capacity≥10000 m^(3)/d)and compared their techno-economy before and after the retrofitting from CAS to MBR.Through cost-benefit analysis,we evaluated the net profit by subtracting the operating cost from the environmental benefit(estimated by the shadow price of pollutant removal and water reclamation).After the retrofitting,the removal rate of pollutants increased(e.g.,from 89.0%to 93.3%on average for NH3-N),the average energy consumption increased from 0.40 to 0.57 kWh/m^(3),but the operating cost did not increase significantly.The average marginal environmental benefit increased remarkably(from 0.47 to 0.66 CNY/g for NH3-N removal),leading to an increase in the average net profit from 19.4 to 24.4 CNY/mJ.We further scored the technical efficiencies via data envelopment analysis based on non-radial directional distance functions.After the retrofitting,the relative cost efficiency increased from 0.70 to 0.73(the theoretical maximum is 1),while the relative energy efficiency did not change significantly.The techno-economy is closely related to the effluent standard adopted,particularly when truncating the extra benefit of pollutant removal beyond the standard in economic modeling.The modeling results suggested that MBR is more profitable than CAS given stricter effluent standards. | Tingwei Gao Kang Xiao Jiao Zhang Wenchao Xue Chunhai Wei Xiaoping Zhang Shuai Liang Xiaomao Wang Xia Huang | 2022 | Frontiers of Environmental Science & Engineering2022，16，4： | 1 |

| 15 | Context-Aware Adaptive Routing for Opportunistic Network显示文摘Opportunistic networking-forwarding messages in a disconnected mobile ad hoc network via any encountered nodes offers a new mechanism for exploiting the mobile devices that many users already carry. However, forwarding messages in such a network is trapped by many particular challenges, and some protocols have contributed to solve them partly. In this paper, we propose a Context-Aware Adaptive opportunistic Routing algorithm(CAAR). The algorithm firstly predicts the approximate location and orientation of the destination node by using its movement key positions and historical communication records, and then calculates the best neighbor for the next hop by using location and velocity of neighbors. In the unpredictable cases, forwarding messages will be delivered to the more capable forwarding nodes or wait for another transmission while the capable node does not exist in the neighborhood. The proposed algorithm takes the movement pattern into consideration and can adapt different network topologies and movements. The experiment results show that the proposed routing algorithm outperforms the epidemic forwarding(EF) and the prophet forwarding(PF) in packet delivery ratio while ensuring low bandwidth overhead. | WANG Xiaomao HUANG Chuanhe ZHOU Hao SHI Jiaoli HE Kai DAN Feng | 2015 | Wuhan University Journal of Natural Sciences2015，20，4： | 1 |

| 20 | MAVP-FE:Multi-Authority Vector Policy Functional Encryption with Efficient Encryption and Decryption显示文摘In cloud,data access control is a crucial way to ensure data security.Functional encryption(FE) is a novel cryptographic primitive supporting fine-grained access control of encrypted data in cloud.In FE,every ciphertext is specified with an access policy,a decryptor can access the data if and only if his secret key matches with the access policy.However,the FE cannot be directly applied to construct access control scheme due to the exposure of the access policy which may contain sensitive information.In this paper,we deal with the policy privacy issue and present a mechanism named multi-authority vector policy(MAVP) which provides hidden and expressive access policy for FE.Firstly,each access policy is encoded as a matrix and decryptors can only obtain the matched result from the matrix in MAVP.Then,we design a novel function encryption scheme based on the multi-authority spatial policy(MAVPFE),which can support privacy-preserving yet non-monotone access policy.Moreover,we greatly improve the efficiency of encryption and decryption in MAVP-FE by shifting the major computation of clients to the outsourced server.Finally,the security and performance analysis show that our MAVP-FE is secure and efficient in practice. | WANG Jing HUANG Chuanhe YANG Kan WANG Jinhai WANG Xiaomao CHEN Xi | 2015 | China Communications2015，12，6： | 1 |
