| 1 | Synthesis and Surface Activity of Novel Triazole-based Cationic Gemini Surfactants显示文摘The synthesis and surfactant activities of two new cationic gemini surfactants containing triazole compound as spacer were described. Their critical micelle concentrations (CMC), which are 1.8×10-4 mol/L and 3.9×10-4 mol/L respectively, are much lower than that of conventional surfactant cetyltrimethyl ammonium chloride (CTAC). In addition, compared with some gemini surfactants containing phenylene, xylylene and stilbenyl as spacer, this new kind of surfactants has good solubility in water at room temperature because of containing more hydrophilic groups or atoms in molecules. | Ling Guang QIU1, 2*, An Jian XIE1, Yu Hua SHEN1* 1School of Chemistry and Chemical Engineering, Anhui University, Hefei 230039 2Institute of Solid State Physics, Chinese Academy of Sciences, Hefei 230031 | 2003 | Chinese Chemical Letters2003,14,6: | 10 |

| 8 | Study on the Characteristics ofSeismic Activity in West China andIts neighboring Regions显示文摘The controlling and influencing effects of the joint action of plates surrounding China on strong earthquakes in Chinese mainland are discussed, and the characteristics of seismic activities in the West of China and neighboring regions are further studied. The results show that the seismic activity in the West of China and neighboring regions not only has the characteristics of high tide and low tide alternation but also has the characteristics of rising in one region while falling in another, and the rise and fall of seismicity are in some proportion. The above characteristics are useful for the prediction of main body region of strong earthquakes in Chinese mainland, especially for the judgement of the ending time of the high tide period. | Chen Yuwei,Shen Yelong and Ling Xueshu Seismological Bureau of Anhui Province, Hefei 230031,China | 2001 | Earthquake Research in China2001,15,3: | 1 |

| 10 | A Trust Scheme Based DRM Model for P2P System显示文摘With the maturation of P2P technology, there are more and more challenges to the protection of digital rights. DRM for traditional Client/Server model can not satisfy the requirement of digital right protection of P2P network. With practical application of P2P network technology and new generational DRM technology, the article proposes a DRM model for P2P system based on trust degree. The proposed model shares the secret key to the trusty peers and affords necessary security ensure for digital content delivery based on P2P technology. Mathematic analyses and simulations show that, compared to the current DRM model, the proposed model is more robust toleration of transmit and security. | XIAO Shangqin LU Zhengding LING Hefei ZOU Fuhao | 2006 | Wuhan University Journal of Natural Sciences2006,11,5: | 0 |

| 12 | Gait Recognition via Cross Walking Condition Constraint显示文摘Gait recognition is a biometric technique that captures human walking pattern using gait silhouettes as input and can be used for long-term recognition.Recently proposed video-based methods achieve high performance.However,gait covariates or walking conditions,i.e.,bag carrying and clothing,make the recognition of intra-class gait samples hard.Advanced methods simply use triplet loss for metric learning,which does not take the gait covariates into account.For alleviating the adverse influence of gait covariates,we propose cross walking condition constraint to explicitly consider the gait covariates.Specifically,this approach designs center-based and pair-wise loss functions to decrease discrepancy of intra-class gait samples under different walking conditions and enlarge the distance of inter-class gait samples under the same walking condition.Besides,we also propose a video-based strong baseline model of high performance by applying simple yet effective tricks,which have been validated in other individual recognition fields.With the proposed baseline model and loss functions,our method achieves the state-of-the-art performance. | Runsheng Wang Hefei Ling Ping Li Yuxuan Shi Lei Wu Jialie Shen | 2021 | Computers, Materials & Continua2021,,9: | 0 |
| 13 | Optimum Transmitter Power Control in WCDMA Cellular Systems显示文摘Power control is an important technique in WCDMA mobile systems for both increasing system capacity and guaranteeing the required QoS (time delay and wireless link transmission quality) of multimedia services. The optimum power control for narrow band CDMA cellular systems is a problem of single threshold optimization. Because these systems have only one type of traffic and have the same QoS requirement. However, WCDMA mobile systems should provide multimedia services and different types of traffic have different QoS requirements. Thus, the power control in WCDMA mobile systems doesn’t be a problem of single threshold optimizing, but turns into the optimizing problem of multi-thresholds. In this paper, we analyze the power control problem in WCDMA cellular mobile systems and propose the optimum transmitter power control algorithm. Three criteria to optimize transmitter power levels of multi-thresholds based on grading the priority orders of multimedia services are proposed. Simulation results show that the proposed algorithms are more effective than conventional algorithms and can provide better performance for WCDMA cellular mobile systems. | Qiu Ling & Zhu Jinkang PCN&SS Lab., University of Science and Technology of China, Hefei 230027, P.R.

| 14 | Comparison between CMM2 & ISO9001显示文摘The Capability Maturity Model(CMM) and ISO9001 are probably the two best known and most widely used models for software organization quality assurance and improvement. As they both continue to evolve, each has a series of versions which own new aspects. This paper discusses the similarities and differences between the two models, based on the CMM version 2.0 c and the 1997 release of ISO9001, examines 20 clauses in ISO9001 and maps them to practices in the latest CMM. In the end, their implementations in China are presented. | Pan Qiu ling, Liu Zong tian, Wu Peng cheng Research Institute of Microcomputer, Hefei University of Technology, Hefei 230009, China | 2001 | Wuhan University Journal of Natural Sciences2001,6,Z1: | 0 |
| 15 | Softev: UML-Based PSEE Environment显示文摘Software development processes, as a mean to ensure software quality and productivity, have been widely accepted within the software development community. This research introduces how to assist developers to establish quality management plan and monitor the implementation of software processes quantitatively in a CASE environment. A PSEE (process centered software engineering environment) named Softev has been brought forward to provide developers the environment to define, execute and monitor their processes. As UML is becoming a standard diagrammatic notation for object oriented modeling and is spreading rapidly, it has been chosen to express the artifacts developed during the requirement analysis and system design stages. In the early products of software process engineering, most research mainly focus on the representations of complex organizational processes and architectures for process centered application support environment. However, the metrics of software processes and artifacts was not paid sufficient attention to. This research proposes the attributes to be measured during the development period which enable managers to predict and supervise the software project more precisely. | Pan Qiu ling, Liu Zong tian, Jia Liang, Xiu Qing,Pan Biao Research Institute of Microcomputer, Hefei University of Technology, Hefei 230009, China | 2001 | Wuhan University Journal of Natural Sciences2001,6,Z1: | 0 |
| 16 | A DRM System Based on Mobile Agent for Digital Rights Redistribution显示文摘We propose a digital rights management (DRM) sys-tem based on mobile agent to protect the copyrights of content providers. In the system, the content provider creates a time lim-ited blackbox out of an original agent and dispatches it to the user end to enforce DRM functions. The blackbox is an agent that can resist the attacks from the malicious user in a certain time interval. Owing to digital rights redistribution support, the user whose rights belong to redistribution category can transfer his rights to other users. Moreover, by introducing public key infrastructure (PKI) and certificate authority (CA) role, the security of the ses-sion can be ensured. An analysis of system security and perform-ance and a comparison with traditional DRM system is given. | LI Ping LU Zhengding ZOU Fuhao LING Hefei | 2008 | Wuhan University Journal of Natural Sciences2008,13,4: | 0 |
| 17 | Multi-Head Attention Graph Network for Few Shot Learning显示文摘The majority of existing graph-network-based few-shot models focus on a node-similarity update mode.The lack of adequate information intensies the risk of overtraining.In this paper,we propose a novel Multihead Attention Graph Network to excavate discriminative relation and fulll effective information propagation.For edge update,the node-level attention is used to evaluate the similarities between the two nodes and the distributionlevel attention extracts more in-deep global relation.The cooperation between those two parts provides a discriminative and comprehensive expression for edge feature.For node update,we embrace the label-level attention to soften the noise of irrelevant nodes and optimize the update direction.Our proposed model is veried through extensive experiments on two few-shot benchmark MiniImageNet and CIFAR-FS dataset.The results suggest that our method has a strong capability of noise immunity and quick convergence.The classication accuracy outperforms most state-of-the-art approaches. | Baiyan Zhang Hefei Ling Ping Li Qian Wang Yuxuan Shi Lei Wu Runsheng Wang Jialie Shen | 2021 | Computers, Materials & Continua2021,,8: | 0 |
| 18 | Chemical composition and size distribution of secondary organic aerosol formed from the photooxidation of isoprene显示文摘Photooxidation of isoprene leads to the formation of secondary organic aerosol (SOA). In this study, the chemical composition of SOA formed from OH-initiated photooxidation of isoprene has been investigated with gas chromatography/mass spectrometry (GC/MS) and a home-made aerosol time-of-fiight mass spectrometer. Sampling particles generated in a home-made smog chamber. The size distribution of SOA particles was detected by a TSI 3321 aerodynamic particle size spectrometer in real time. Results showed that SOA created by isoprene photooxidation was predominantly in the form of fine particles, which have diameters less than 2.5 μm. The obtained mass spectra of individual particles show that products of the OH-initiated oxidation of isoprene contain methyl vinyl ketone, methacrolein, formaldehyde, and some other hydroxycarbonyls. The possible reaction mechanisms leading to these products were also discussed. | LIU Xianyun, ZHANG Weijun, WANG Zhenya, ZHAO Weixiong, TAO Ling, YANG Xibin Laboratory of Environmental Spectroscopy, Anhui Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, Hefei 230031, China. | 2009 | Journal of Environmental Sciences2009,21,11: | 0 |
