| 2 | Consensus of high-order dynamic multi-agent systems with switching topology and time-varying delays显示文摘This paper studies the consensus problems for a group of agents with switching topology and time-varying communication delays,where the dynamics of agents is modeled as a high-order integrator.A linear distributed consensus protocol is proposed,which only depends on the agent's own information and its neighbors'partial information.By introducing a decomposition of the state vector and performing a state space transformation,the closed-loop dynamics of the multi-agent system is converted into two decoupled subsystems.Based on the decoupled subsystems,some sufficient conditions for the convergence to consensus are established,which provide the upper bounds on the admissible communication delays.Also,the explicit expression of the consensus state is derived.Moreover,the results on the consensus seeking of the group of high-order agents have been extended to a network of agents with dynamics modeled as a completely controllable linear time-invariant system.It is proved that the convergence to consensus of this network is equivalent to that of the group of high-order agents.Finally,some numerical examples are given to demonstrate the effectiveness of the main results. | Fangcui JIANG,Long WANG,Guangming XIE(Institute of Intelligent Engineering,Center for Systems and Control,College of Engineering,and Key Laboratory of Machine Perception(Ministry of Education),Peking University,Beijing 100871,China) | 2010 | 控制理论与应用(英文版)2010，8，1： | 11 |
| 3 | 抗磷脂综合征诊疗指南显示文摘静脉血栓主要指深静脉血栓形成(deep vein thrombosis,DVT),最常见的部位为腓肠肌静脉,其次为股静脉。深静脉血栓形成相当多见,在美国人群的年发病率为0.1%,每年有超过20万人患DVT,大约10%的DVT患者发生肺栓塞。欧美国家对DVT的诊治与病因研究做了大量的工作,特别是近年来随着临床检验技术与分子生物学的发展,易栓症的各种发病机制已相继发现。约一半的易栓症患者的病因可被确定。 我国尚无DVT的统计资料,一般的印象是低于西方人群,但临床病例日益增多,有的医院已建立了专科病房。总的来讲,我国在心脑血管疾病方面做的工作较多,但对DVT的研究还处于早期阶段,在深度与广度上与国际水平还有较大的距离。另一方面,中国人易栓症发生情况与西方人似有较大的差别。因子VLeiden仅发现两例,凝血酶原G20210A变异尚未见报导。近年来我国血液学会对静脉血栓栓塞的诊断与治疗提出了一系列的指导意见,我们组织翻译了有关资料供有关医务人员参考,以期进一步提高我国DVT的诊断与防治水平,并希望对确定我国DVT诊断与治疗的原则及发展规划有一定的意义。我们将分5个专题介绍这些指导意见,本期介绍的'抗磷脂综合征诊疗指南';'有症状门诊病人深静脉血栓形成的诊断,临床评价和D-二聚体分析可能减少对影像学诊断的需要'。 | Greaves M Cohen H Machin SJ Mackie I 白艳艳 王兆钺 | 2004 | 国外医学(输血及血液学分册)2004，27，5： | 9 |
| 4 | KD(D&K) and Double-Bases Cooperating Mechanism显示文摘KD(D&K) (Synthesized Knowledge Discovery System based on Database and KnowledgeBase Cooperating Mechanism) is first advanced in this paper on the basis of KDD (KnowledgeDiscovery System based on Database) and KDK (Knowledge Discovery System based on KnowledgeBase). KD (D&K) is not simple addition of KDD and KDK but a new system with absolutelynew character and essential development, which is distinct from KDD and KDK and includes them.Not only the generalized structural frame of control rules KD (D&K) acquiring method is proposed,but also the theoretical basis of its key technical problem--don ble-bases cooperating mechanism isdiscussed according to the original academic idea to restrict KDD by basic knowledge base. | Yang Bingru(School of information Engineering,University of Science and Technology of BeiJing,100083, P.

| 6 | Laplacian smoothing transform for face recognition显示文摘In this paper, we investigate how to extract the lowest frequency features from an image. A novel Laplacian smoothing transform (LST) is proposed to transform an image into a sequence, by which low frequency features of an image can be easily extracted for a discriminant learning method for face recognition. Generally, the LST is able to be an efficient dimensionality reduction method for face recognition problems. Extensive experimental results show that the LST method performs better than other pre-processing methods, such as discrete cosine transform (DCT), principal component analysis (PCA) and discrete wavelet transform (DWT), on ORL, Yale and PIE face databases. Under the leave one out strategy, the best performance on the ORL and Yale face databases is 99.75% and 99.4%; however, in this paper, we improve both to 100% with a fast linear feature extraction method for the first time. | GU SuiCheng, TAN Ying & HE XinGui Key Laboratory of Machine Perception (MOE) Department of Machine Intelligence, School of Electronics Engineering and Computer Science Peking University, Beijing 100871, China | 2010 | Science China(Information Sciences)2010，53，12： | 6 |
| 7 | Mining geographic episode association patterns of abnormal events in global earth science data显示文摘Abnormal events in earth science have great influence on both the natural envi-ronment and the human society. Finding association patterns among these events has great significance. Because data in earth science has characteristics of mass,high dimension,spatial autocorrelation and time delay,existing mining technolo-gies cannot be directly used on it. We propose a RSNN (range-based searching nearest neighbors) spatial clustering algorithm to reduce the data size and auto-correlation. Based on the clustered data,we propose a GEAM (geographic episode association pattern mining) algorithm which can deal with events time lags and find interesting patterns with specific constraints,to mine the association patterns. We carried out experiments on global climate datasets and found many interesting association patterns. Some of the patterns are coincident with known knowledge in climate science,which indicates the correctness and feasibilities of our methods,and the others are unknown to us before,which will give new information to this research field. | WU TianShu,SONG GuoJie,MA XiuJun,XIE KunQing,GAO XiaoPing & JIN XingXing Key Laboratory of Machine Perception,Ministry of Education,and Department of Machine Intelligence,Peking University,Beijing 100871,China | 2008 | Science China(Technological Sciences)2008，51，S1： | 5 |

| 10 | A malware detection model based on a negative selection algorithm with penalty factor显示文摘A malware detection model based on a negative selection algorithm with penalty factor (NSAPF) is proposed in this paper. This model extracts a malware instruction library (MIL), containing instructions that tend to appear in malware, through deep instruction analysis with respect to instruction frequency and file frequency. From the MIL, the proposed model creates a malware candidate signature library (MCSL) and a benign program malware-like signature library (BPMSL) by splitting programs orderly into various short bit strings. Depending on whether a signature matches 'self', the NSAPF further divides the MCSL into two malware detection signature libraries (MDSL1 and MDSL2), and uses these as a two-dimensional reference for detecting suspicious programs. The model classifies suspicious programs as malware and benign programs by matching values of the suspicious programs with MDSL1 and MDSL2. Introduction of a penalty factor C in the negative selection algorithm enables this model to overcome the drawback of traditional negative selection algorithms in defining the harmfulness of 'self' and 'nonself', and focus on the harmfulness of the code, thus greatly improving the effectiveness of the model and also enabling the model to satisfy the different requirements of users in terms of true positive and false positive rates. Experimental results confirm that the proposed model achieves a better true positive rate on completely unknown malware and a better generalization ability while keeping a low false positive rate. The model can balance and adjust the true positive and false positive rates by adjusting the penalty factor C to achieve better performance. | ZHANG PengTao 1,2 , WANG Wei 1,2 & TAN Ying 1,2 1 Department of Machine Intelligence, School of Electronics Engineering and Computer Science, Peking University, Beijing 100871, China 2 Key Laboratory of Machine Perception, Ministry of Education, Peking University, Beijing 100871, China | 2010 | Science China(Information Sciences)2010，53，12： | 4 |
| 11 | 口服抗凝剂指南(第三版)显示文摘英国血液学标准委员会(BCSH)1990年曾修订了口服抗凝剂指南以反映医学的发展并结合了医学评估的结果,1993年又发表了肝素指南,两份指南包括口服抗凝剂的适应范围和对抗凝治疗安排的建议。本次发表的新指南是考虑到需长期抗凝的患者数量迅速扩展,对其进行安全监控存在着实际困难。在过去5年中,临床抗凝治疗的患者数量增加了两倍多,并有继续增多的趋势,相应地就出现了组织上的问题。血液学家有责任帮助地方确定实验室检测方法与恰当的口服抗凝剂的治疗剂量,这需要国家和地方参与质量评估计划以及对临床工作的评估。 | Walker ID Machin S Baglin TP 吴淑燕 王兆钺 | 2004 | 国外医学(输血及血液学分册)2004，27，6： | 4 |
| 12 | A study on controlled cooling process for making bainitic ductile iron显示文摘In the present research, TTT curve of bainitic ductile iron under the condition of controlled cooling was generated. The cooling rate of grinding ball and its temperature distribution were also measured at the same time. It can be concluded that the bainitic zone of TTT curve is separated from the pearlitic zone. As compared to the water-quenching condition, more even cooling rate and temperature distribution can be achieved in the controlled cooling process. The controlled cooling can keep away from pearlitic zone in the high temperature cooling stage and produce similar results to the process of traditional isothermal cooling with a low cooling rate in the low temperature cooling stage. | ~*Y.

| 13 | Adiabatic Shear Bands in 30CrNi_3MoV Structural Steel Induced during High Speed Cutting显示文摘The width and spacing of adiabatic shear bands (ASBs) in the serrated chips generated during high speed orthogonal cutting of 30CrNi3MoV structural steel were measured by optical microscopy (OM), the temperature rise in the shear band was estimated. The microstructures of the ASBs were also characterized by SEM and TEM. The results show that the width and spacing of ASBs decrease with the increase of the cutting speed. The further observations show that the microstructure between the matrix and the center of the ASB gradually changes, and that the martensitic phase transformation, carbide precipitation and recrystallization may occur in the ASB. | Chunzheng DUAN and Minjie WANGKey Laboratory of Ministry of Education for Precision and Non-traditional Machining, School of Mechanical Engineering, Dalian University of Technology, Dalian 116024, China | 2004 | Journal of Materials Science & Technology2004，20，6： | 3 |
| 14 | In situ synthesis and phase analysis of low density O'-sialon-based multiphase ceramics显示文摘In situ formed low density O'-sialon-based multiphase ceramics were prepared by liquid-phase sintering method at 1400°C with Si3N4, SiO2 and Al2O3 as raw materials.Crystalline phases were identified by X-ray diffraction(XRD).The quantitative phase analysis was finished by matrix-flushing method and the substitution parameter x value of O'-sialon was estimated.The effects of sintering additives on the phase composition of the material were studied.The results show that, when using Y2O3 alone, Al6Si2O13 phase can be formed in the material, but when using Y2O3 and MgO, MgAl2O4 phase can be preferentially formed and the Al6Si2O13 is not observed.The mechanical properties of the material were measured and the relationships between microstructure and mechanical properties were discussed.The sample with Y2O3 and MgO sintering additives, using fused quartz alone as SiO2 source, displays a combination of high bending strength(163 MPa) and good fracture toughness(3.11 MPa·m1/2).Bending strength and fracture toughness of the samples increase with the increase of the content and aspect ratio of elongated grains and decrease with the increase of the porosity. | XU Xiongwen, LIANG Hui, LI Xiaolei, JI Huiming, LU Huixiang, and WAN Yizao Key Laboratory for Advanced Ceramics and Machining Technology(Ministry of Education), Tianjin University, Tianjin 300072, China | 2010 | Rare Metals2010，29，2： | 3 |

| 19 | Damage mechanisms during lapping and mechanical polishing CdZnTe wafers显示文摘CdZnTe wafers were machined by lapping and mechanical polishing processes,and their surface and subsurface damages were investigated.The surface damages are mainly induced by three-body abrasive wear and embedded abrasive wear during lapping process.A new damage type,which is induced by the indentation of embedded abrasives,is found in the subsurface.When a floss pad is used to replace the lapping plate during machining,the surface damage is mainly induced by two-body abrasive and three-body abrasive wear,and the effect of embedded abrasives on the surface is greatly weakened.Moreover,this new damage type nearly disappears on the subsurface. | LI Yan,KANG Renke,GAO Hang,and WU Dongjiang Key Laboratory for Precision and Non-Traditional Machining Technology (Ministry of Education),Dalian University of Technology,Dalian 116024,China | 2010 | Rare Metals2010，29，3： | 2 |
| 20 | Quantitative Analysis of the Loads Acting on the Abrasive Grits in the Diamond Sawing of Granites显示文摘An experimental study was carried out to quantitati ve ly evaluate the loads acting on the diamond grits during circular sawing of two kinds of typical granite with diamond segmented saw blade. Measurements were mad e of the horizontal and vertical force components and the consumed power in order to obtain the tangential and the normal force components. The temperatures at the diamond-granite contact zone were measured using a foil thermocouple. T he measurement, together with the net sawing power, was subsequently used to est imate the energy partition to the granite by a temperature matching technique. B ased on the energy partition values, the temperatures at individual cutting poin ts were estimated using an analytical model. SEM was used to follow the topograp hies of worn diamond segments. The average force acting on each diamond grit was found to be only 4% of the diamond compressive strength measured by a static me thod. The strength disparity of diamond grits and the random protrusion of grits beyond bond matrix should be significant factors in accounting for the wear of diamond grits. The wear of diamond grits was also found to be closely related to the high temperatures generated at individual cutting points and the pop-outs of diamonds from the bond matrix might be mainly attributed to the heat conducte d to the segments. | XU Xi-peng, LI Yuan, ZENG Wei-ming, LI Liang-bin (Province Key Lab of Stone Machining, Huaqiao University, Quanzhou 362 011, China) | 2002 | 厦门大学学报(自然科学版)2002，41，S1： | 2 |
