(* IMBIZO is a Zulu word meaning a ‘meeting or gathering’). Overall theme of IMBIZO lll : The future of marine biogeochemistry, ecosystems and societies. Multi-dimensional approaches to the challenges of global change in continental margins and open ocean systems Summary Marine ecosystems are essential to life as we know it on this planet, yet the oceans are undergoing fundamental change. More than 20% of the global population resides within 100km of the coast, leading to increasing pressure on the ecosystems in continental margins; more than 90% of natural and farmed fish production is supported by the continental margin ecosystems, thus serving as an important food source. Meanwhile, global change has added a new set of threats, such as increased acidification and warming of the oceans. Humans are both a driver and a recipient of this change and it has become increasingly critical to understand, at multiple scales from the local to the global, how biogeochemical cycles, ecosystems, societies, governments and people, might respond to these changes and threats. The objective of IMBIZO lll is to explore the linkages and interactions between humans and marine systems to create understanding of the possible futures of the interrelated ecological and biogeochemical systems in the continental margins and in the open ocean and their societal implications . Meeting format We will follow the proven IMBIZO format of three concurrent but interacting workshops, and joint plenary and poster sessions. This has been found to provide a forum for stimulating discussion between interdisciplinary experts and also linkages between biogeochemistry, ecosystem and social science research. To facilitate effective discussion, each workshop will be limited to 40 participants, so participation will be selective. The participants, coming from communities with active interests in the topics, will be chosen to provide balance in scientific disciplines as well as geographic distribution Workshops Each of the three workshops will include oral and poster presentations to showcase the current state of knowledge in each area and discussion sessions to identify key questions to be addressed by IMBER. We would like to invite members of the community to provide ideas for the themes of the three workshops. The workshops should be related to the overall theme of the IMBIZO and should foster the collaboration between the natural and social sciences. Please include a short description of the proposed workshop topic and indicate how this addresses the overall IMBIZO goals. Also please include a list of potential conveners. Please send your suggestions to Lisa Maddison ( Lisa.Maddison@univ-brest.fr ) before 15 November 2011.

2011 EU-China Workshop on Complexity Science Talk Abstract TAIPEX —An Online ExperimentalPlatform to Study Market Behavior Sai-Ping Li Institute of Physics, Academia Sinica, Taipei 115, Taiwan The TAIPEX , which is one of the existing prediction market platforms in the world, was first set up in early 2004 in Taiwan as an experimental toolto study the voting behavior of the people in Taiwan. After the first successful experimental launchon this platform, it was soon realized that one couldin fact study financial market behaviors by using this platform. In subsequent years, that is, from early 2004 till theend of 2010, eight experiments have been carried out onthis prediction market platform. These include: three presidential elections (2 from Taiwan and one from the US), one parliamentary election, three city mayor elections and one on bird flu. From the results of these experiments, we have observed many stylized facts that are known to exist in everyday financial markets. For example, Figure 1 shows the probability density of normalized price returns of TAIPEX in the 2004 Taiwan parliamentary election with different time lagsequal to 55(red), 148(black), 403(yellow), 1097(green) and 8103(blue) minutes. The figure illustrates two interesting features. The firstfeature is the heavy tails onthe two ends ofthe curves. One can see this easily when compared to a Gaussian distribution as shown in the figure. Heavy tails of price returns in financial markets arestylized facts that are knownto market practitionersfor a long timeand our experiments also exhibitsuch a feature. Another feature that we can observe in this figure is the universality of different time lag curves. One can see that the different time lag curves can indeed be represented by a single distribution curve. We also observe that other well known stylized facts also appear in our prediction mark Figure 1. Probability density of normalized price returns with time lag equal to 55(red), 148(black), 403(yellow), 1097(green) and 8103(blue) minutes. The dashed line was obtained from a Cauchy distribution and the dotted line is a Gaussian distribution of unit variance. Aside from the already well known stylized facts, we have further uncovered many features that are likely to exist but are unable to be detected in financial markets. Take, for example, we can construct a trading network of the traders from the data of the experiment on this prediction market platform . The same kind of networkis unlikely to be constructed due to the lack of data availabilityin real financial markets. Figure 2 is an illustration of a trading network among traders of our experiment on the 2006 Taipei Mayor Election. The network is based on the data from Day 3. The number of traders and the trading network grew sincetherewere more registered players to do trading on the platformas the experiment continueduntil the dayof the election. Figure 2. The trading network on Day 3 of the 2006 Taipei Mayor Election experiment. The network consists of 40 interconnected nodes. isolated nodes are not shown here . In this talk, we will first give abrief introduction of the historical development and the current status ofprediction markets. As an example of how prediction markets work, we will give details of doingtrading on our prediction market platform. Results of our previous experiments will be summarized and presented, including the most recent experiment done by the end of 2010. Possible future work will beproposed and discussed. Most importantly, collaborations on this prediction market platform are welcome. References: http://socioecono.phys.sinica.edu.tw/ K.J. Arrow et.al., Science 320(2008)877-8 G. Tziralis and I.

Piecewise Smooth Lyapunov Function for a Nonlinear Dynamical System Yan Gao Business School, University of Shanghai for Science and Technology, Shanghai 200093, China email:gaoyan@usst.edu.cn In this paper, stability and attraction for a nonlinear dynamical system with nonsmooth Lyapunov function are studied. The previous results on stability and attraction with a max-type Lyapunov function are extended to the case where Lyapunov function is piecewise smooth. A condition, under which stability and attraction is guaranteed with a piecewise smooth Lyapunov function, is proposed. Taking two certain classes of piecewise smooth functions as Lyapunov functions, related conditions for stability and attraction are developed. Key Words. Nonlinear dynamical system, stability, region of attraction, Lyapnov functions, nonsmooth analysis, piecewise smooth function.

By introducing a proper competitive mechanism, it was first found by Achlioptas, D'Souza, and Spencer and was subsequently studied intensely by other scientists that the bond percolation in random networks became discontinuous. Such kind of percolation has a delayed transition point but still maintain a power-law critical cluster distribution with yet the exponent different from the classical one, indicating the absence of universality in sense of different percolation strategies. However further numerical and theoretical studies have provided evidences that the bond explosive percolation in random network is actually continuous in the thermodynamics limit except for the global competitive case in which all the links in network participate in the selection. Although the argument still exists, explosive percolation has brought new insights to the percolation theory. However the two most important properties, namely the location of the critical point and the critical cluster distribution have not been studied systematically. Previous studies presented the related results only for their special models, which neither provide any general conclusions nor help to understand the possible universal behavior. In this letter, we focus on this problem instead of just studying the continuity of explosive percolation. By introducing a best-of-m competitive rule the explosive site percolation in ER network is studied. We prove that the critical point tc(m, k) has a nontrivial limitation Tc(k) 1 as m = N →∞. By developing a finite size scaling method, Tc(k) is found to scale asymptotically as . The result is further generalized by for all m with approximated by an arctan function. The critical cluster distribution is found to be power law with exponent about -2.5 regardless of m, leading to a conjecture that the universality remains in sense of different percolation strategy. The continuity of the percolation is also discussed. The present results basically generalize the classical conclusion to adapt to a large class of explosive percolation. Key words: explosive percolation, random network, critical point, critical cluster distribution Fluctuation scaling in complex networks Ding-ding Han School of Information Science and Technology, East China Normal University, Shanghai 200241, China Fluctuation is a universal phenomenon in complex networks. Since L.R.Taylor’s influential paper on natural populations was published in 1961, a scaling relationship has been observed in a wide range of disciplines, ranging from population dynamics through the Internet to the stock market. The original law exhibits that for any fixed species there is a power-law scaling between fluctuations in the size of a population (characterized by standard deviation) and the average population, namely In this paper, brief introduction about fluctuation scaling is given. The fluctuation can be divided into temporal fluctuation scaling and ensemble fluctuation scaling. Besides, we have investigated the evolution of the download network for the rank-ordered papers which were listed in Zhang’s Econophysics web page. From 2004 to 2007, the download distribution shows the change of the exponents even though the rank-ordered distribution still keeps scale-free feature, reflecting the change of traffic on nodes which represent the given downloaded papers. Further, we give a quantitative analysis for the average download rates per day, which shows day-by-day fluctuation. The average flux shows a fast exponential decay as a function of the rank, while the dispersion does not show an obvious dependence of the rank. Interestingly, the dispersion of the download rate distributions shows power-law scaling behavior with its average flux, namely . In different time windows ranging from about 6.5 months to 31 months in which the download distributions are accumulated, the scaling parameter changes with the time windows, namely from 0.60 to 0.89. The origins are qualitatively interpreted by two models. Future work on quantitative model simulation and a possible -scaling of network fluctuation is in progress. Key words: Fluctuation scaling; complex netwrks; random walker model; fluctuation exponent; time window Long division unites - long union divides, A model for cultural evolution J. Jiang, R. Wang, Michel Pezeril, and Q.A. Wang One of the historical phenomena in the time evolution of cultural, national and economic systems is the transition between union and division of one or several entities. In this work, we propose a union-division model based on the maxim "long union divides and long division unites" in order to investigate the long time behaviors of the networks composed of nodes representing the above mentioned entities. Each node is characterized by several quantities such as identity, ingredient, richness, and age. The time evolution of the network is probabilistic depending on the above quantities and on the interaction between the neighboring n nodes. This work offers a long term view on the apparently periodic dynamics of an ensemble of cultural entities. Self-organization and Preconditions of Efficient Markets You-Gui Wang Department of Systems Science, School of Management, Beijing Normal University, Beijing 100875, China, Email: ygwang@bnu.edu.cn Most of economists have devoted themselves into proving the existence of “invisible hand” in marketing systems. Traditional approaches claim that an efficient market lies on three presuppositions: rationality of individual market participants, complete information and equilibrium of the market. These presumptions result from the static postulations of mainstream economics. In this talk, I will show that from dynamic perspective a market can achieve an efficient state without those strong assumptions. The patterns of self-organization of an evolutionary market are displayed where the premises of individual rationality, single price as well as equilibrium are abandoned. Keywords: Market efficiency, Self-organization, Rationality, Market equilibrium, Dynamic structure. Accelerating growth and size-dependent distribution of human online activities Zhang Jiang Department of Systems Science, School of Management, Beijing Normal University, Beijing 100875, China, Research on human online activities usually assumes that total activity T increases linearly with active population P, that is, T ∝ P^γ (γ = 1). However, we find examples of systems where total activity grows faster than active population. Our study shows that the power law relationship T ∝ P^γ (γ 1) is in fact ubiquitous in online activities such as microblogging, news voting, and photo tagging. We call the pattern “accelerating growth” and find it relates to a type of distribution that changes with system size. We show both analytically and empirically how the growth rate γ associates with a scaling parameter b in the size-dependent distribution. As most previous studies explain accelerating growth by power law distribution, the model of size-dependent distribution is worth further exploration. Statistics and Evolution of Donations for 2008 Wenchuan Earthquake Qinghua Chen ( 陈清华 ), Yajing Wu ( 吴亚晶 ), Jinzhong Guo( 郭金忠 ), Yougui Wang( 王有贵 ) Department of Systems Science, School of Management, Beijing Normal University, Beijing 100875, People's Republic of China qinghuachen@bnu.edu.cn (86-10-58802732) Based on the data of individual donations from Chinese Red Cross Foundation , this paper analyzes and discusses the distribution of individual donations and evolutions of some statistical properties over time. The results show: 1) individual donations distribution has shown some power law characters, and some donation numbers are preferred; 2) the growths of person times and total donations obey Logistic growth, and the growth of person times is ahead of another; 3) the trend of average donations amount is that, firstly decreases and then increase, with large donations coming at a subsequent time or stage . This paper proposes a multi-agent model to simulate donations’ evolution based information diffusion. Figure 1. Zipf’s plot of donations Figure 2. Pareto’s plot of donation Figure 3.

Our research focus is how the clustering structure, social diversity and aspiration-induced migration affect the cooperative behavior. We find that the higher clustering coefficient enhances the cooperation in spatial public goods game. Due to the existence of social diversity, the influence of different individuals is different. The influence of an individual is defined as the power of its degree, where the power exponent is an adjustable parameter. During the evolutionary process, every individual chooses one of its neighbors as a reference with a probability proportional to the influence of the neighbor. It is found that for the fixed value of the temptation to defect, there exists an optimal value of , leading to the highest level of cooperation. We propose an aspiration-induced migration in which individuals will migrate to new sites provided that their payoffs are below some aspiration level. It is found that moderate aspiration level can best favor cooperative behavior. Cooperation percolation in spatial evolutionary games is specially considered. We study the dynamical organization of cooperator clusters in prisoner’s dilemma game on regular and complex networks. It has been found that when the initial concentration of cooperators in the systems exceeds a threshold, there is a phase transition characterized by the emergence of a giant spanning cooperative cluster of the order of network size. Depending on the network structure and the temptation to defect, the phase transition appears to belong to different universality classes of percolation, including regular percolation, invasion percolation and other unreported classes. Transportation Dynamics on Mobile Node Network Most existing works on transportation dynamics focus on the networks of a fixed structure, but networks whose nodes are mobile have become widespread, such as cell-phone networks. We introduce a model to explore the basic physics of transportation on mobile networks. Of particular interest are the dependence of the throughput on speed of agent movement and communication range. Our computations reveal a hierarchical dependence for the former, while for the latter we find an algebraic power law between the throughput and the communication range with an exponent determined by the speed. We develop a physical theory based on the Fokker-Planck equation to explain these phenomena. Our findings provide insights into complex transportation dynamics arising commonly in natural and engineering systems. Reference: Phys.Rev.E 83.016102(2011) Newsbag, an adaptive model for news recommendation Dott. Giulio Cimini Uni Fribourg and Univ. Rome, Italy We propose an adaptive recommendation model which combines similarities in users' rating patterns with epidemic-like spreading of news on an evolving social network. Our system has high filtering efficiency and robustness against malicious behavior, and outperforms other widely adopted recommendation methods. The model also sheds light on who people do follow in social communities and where they do search for good information sources. Agenetic perspective on citation networks Dott. Stanislao Gualdi Uni Fribourg and Univ. Rome, Italy we develop an analytical framework to asses genetic relations between papers. We show that such framework can be used both to highlight papers which play a fundamental role in the development of a research field both to build a recommender system which filters relevant literature for a given interest. The spectral analysis for biology networks Jiao Gu ( 辜姣) Central China Normal University , Wuhan , P.R.China We constructed the protein network and domain networks from the database. Baced on the analysis ofspectrumof normalized Laplacian matrix, we could classify the networks and find phylogenetic information from these networks. Statistical Mechanics of Social Tagging Networks: Structure, Dynamics and Function Zike Zhang (张子柯) University of Fribourg, Switzerland In this talk, I would introduce our recent progress on the study of social tagging netowks, including the structure of how to describe and measure it, the dynamics of how it evolves and it application in recommender systems. It is expected to give a general picture of Social Tagging Networks and possible research topics, as well as challenges. Potentials of sino-european cooperations in complexity sciences Jian-Wei Zhang University of Hamburg , Hamburg , German European and China cooperation opportunities in Complexity Sciences Jeff Johnson Open University, London, UK Complexity of systems with respect to the economy and society Dr. Fred von Gunten International Strategy and Competition University of Fribourg , Switzerland “Complexity research as an interdisciplinary undertaking is concerned with the question how orders, structures, chaos and break downs can be created by the relationships of many elements of a complex system… The object of complexity research is to identify and understand chaos, tensions and conflicts in complex systems (molecules in materials, cellules in organisms or human beings in markets and organisations) so as to acquire new knowledge for the potential of establishing new orders.” Mainzer, 2008, Komplexitt, p. 10). When this definition is applied to the economy and society then a number of difficulties have to be overcome. In this contribution one attempts to explain how three basic propositions contribute to improving the situation. First, market or state capitalism must be identified as organised socio-economic systems. Second, these systems must be presented as three level economies instead of only two level economies. Third, in the end, “pure analysis” in the economic and social sciences must be integrated with the other sub-systems of the nation-state, at the international level with international organisations. That way the degree of complexity of systems with respect to the economy and society can be positively influenced

[转载]KITPC 2011 March Program 统计物理与复杂网络之交叉学科应用
KITPC Kavli Institute for Theoretical Physics China at the Chinese Academy of Sciences Web page: http://www.kitpc.ac.cn/program.jsp?id=PI20110501 Interdisciplinary Applications of Statistical Physics Complex Networks Date : From 2011-03-01 To 2011-04-01 International coordinators : Mikko Alava, Erik Aurell, Yi-Cheng Zhang Local coordinators : Bing-Hong Wang, Ke Xu, Haijun Zhou(Contact Person),Tao Zhou Main | Pictures | Schedules talks | Sub-Program | Participants | Discussion | Apply This five-week program (28 Feb-01 April, 2011) is a continuation of the 2008 KITPC program “Collective Dynamics in Information Systems”. the first two weeks focus on topics (1) and (2),and the last two weeks focus on topics (4) and (5), and the middle week will discuss issues that are interesting to both the spin-glass/information science community and complex network community. The main focuses of this new program are: (1) Statistical Physics of constraint satisfaction problems and learning problems Methods from statistical physics are gaining increasing acceptance in information theory and computer science . In the last few years, statistical physicists in the field have increasingly moved beyond inference to learning. Technically, inference means finding out properties of a model, which is defined and known. Learning means finding out what the model is from observations. Arguably this has an even wider applicability to computer and information sciences. New statistical physics-inspired algorithms has the potential to revolutionize neural-science (learning from measurement on many neurons at the same time) and 'omics' (learning from measurements on many genes at the same time), and certainly also many other fields of science and technology. (2) Statistical physics of Peer-to-peer (P2P) systems Computational and communicating entities are spreading over the face of the earth. PCs and cell phones, alive and connected at any one time, already count in the billions or tens of billions. With the projected exploration of sensor networks, embedded systems and various forms of "smart dust", the total aggregate number will soon be in the trillions. Only a very small fraction of this computational and communicative power is used to execute centrally designated and coordinated tasks. Most entities lead partly autonomous lives, executing locally stored programs, and reacting to local information and input. The description of large collections of such entities, and their properties in the large, is a new promising area of statistical physics. (3) Network-based information physics The research fields of information physics are widespread. All researches on information based on internet and carried on by means of physics could be called information physics. The important questions that will be discussed in this program include: (a) Data mining and presonalized recommendation on world-wide web; (b) User bahavior analysis in Web; (c) Internet and WWW's frames and mechanism of evolution; and (d) Dynamics research on Internet and WWW. (4) Statistical physics of complex networks The complex network has been attractive in recent ten years not only as the pattern discovered ubiquitously in real world, but also as the unifying framework to understand inherent complexity in nature. The topics of interests in this workshop will cover fundamental concepts and mathematical features of complex networks as well as their applications in a variety of disciplines including physics, biology, information science, sociology, and economics. The discussion emphasis will be laid on the following focusing subjects. (a) Fundamental theory and statistical physics for the complex systems based on network structure (b) Synchronization and control of chaos in nonlinear dynamical systems (c) Topology structure, function and dynamics of the complex networks (d) Cascading and synchronization in the complex network (e) Epidemic spreading and opinion promulgation along the networks (f) Consensus and swarm for self-driven agents (g) Dynamical modeling and statistical mechanical analysis of human behaviors (h) Social network analysis, social dynamics and social physics (i) Complex adaptive systems, minority game and econophysics (j) Cooperation evolution and game models (k) Phase transition and self-organized criticality in traffic flow, city vehicle transportation complex system (l) Systems biology and life complexity

欧美教授更具社会责任感
jianxu 2010-10-16 19:50
10 月 12-15 日,在北京参加了 Sino-German Workshop of building the bridge between physics and material science in amorphous metal 。期间,中德两国科学家就非晶态金属的研究,特别是一些基本科学问题的研究进展进行了交流。除了中德两国之外,还特别邀请了几位本领域的美国科学家参加。 Workshop 的显著特点就是大家讨论。此次 workshop 全面向学生开放(免费参加),参与讨论。 德方的组织者特别鼓励学生们向教授们提出问题 。每天的最后时段,保留有 1 个小时的 Panel Discussion 时间,供学生们针对当天的报告内容提出问题,由教授们来回答。学生们也很活跃,提出各种各样的问题,许多也是他们素日累积的困惑。教授们(主要是老外)耐心地讲解。 如此场景是我们在国内学术会议上绝对看不到的! 一些资深的教授即使是在茶歇期间也被学生们围住,耐心地讲解一些基本的概念,纠正学生们的一些不到位的理解,介绍某些科学问题的历史沿革。老外们也对中国学生们拥有较好的英语水平颇为意外。据说,他们也与日本人合办过类似的会议,日方学生的英语水平远不如我们中国学生,成为交流的障碍。 与会的中国教授们都很忙,能够坚持三天下来一直专心听会者,仅有少数几位。 很多人做完自己的报告,便拂袖而去。 赶场 去应付其它与搞钱直接有关的会议。 一句话,对于学问没兴趣。 对自己知识的匮乏,也没有丝毫的不好意思。 .......... Workshop 结束的次日早上,我与德方的组织者 S 教授在旅馆的餐厅里巧遇,一起共进了早餐。他对会议很满意。他对我说,你在这个领域里工作十多年了,当然对很多东西都很熟悉,容易理解。但学生们就不同了,他们可能会感到很困难,一头雾水。你经常参加国际会议,这个 workshop 结束后,你也不会有什么深刻的印象。可是学生们就不同了,这个 workshop 会让他们终生难忘。很可能会唤起其中的某些人对科学问题的兴趣或者激发他们的学术潜质,乃至改变他们未来的职业生涯与生活。他问我,你第一次参加 workshop 是哪一年?回答是 1994 年。他说,他第一次参加 workshop 是在七十年代,第一次见到了该领域的大牌(老一辈)科学家,当时对许多术语和基本概念都不懂,脑子里一片空白。对报告当然也听不太懂,晚上回去便整理、写下每天的笔记,进一步地思考与理解。我们应该积极地鼓励学生们去提问题,不怕他们犯有错误。他还建议我们合办一些 summer school ,由教授们针对某些专题问题给学生们上课,讲解,让学生们尽快地掌握基本概念,夯实专业基础。 Workshop 结束了,令我感受深刻的是, 欧美国家的教授们远远比我们更加具有社会责任感,更大气,站得更高,看得更远 。 他们这些资深科学家的使命早已发生了悄然转变 ,不再是为自己(或者自己掌控的利益集团)搞项目、捞钱、争资源,而考虑的是如何吸引优秀、睿智、真正有潜质的年轻人进入他们所在的研究领域,真正让这一科学领域得到可持续地发展。 也正因如此,他们在年轻一代的心目中赢得的是人格魅力与学术上的尊严!

德国某大学的workshop见闻与感触
sonobody 2010-6-8 16:28
在德做访问学者期间,有幸参与所在单位每年冬天举办的为期三天的workshop。幸运的是,这次的workshop所用的语言是英语,尽管他们99%都是德国人(平时的报告大都是德语的,令我望尘莫及)。 在一个飘雪的隆冬季节,我们浩浩荡荡二十余人,驱车40分钟,带着三天的吃喝,背上夜宿的睡袋,踩着没膝的积雪,深一脚浅一脚地抵达了一个山脚下前不着村后不着店的林间小木屋。本以为小木屋是一个很原始的简陋房子,没想到里边的设施还很现代,活动室、厨房、餐厅、卧室、卫生间等一应俱全。外面滴水成冰,室内却很温暖。刚开始我天真地以为暖气是靠厨房里的壁炉供热的,后来经人指点才知道靠的是燃气壁挂炉;厨房里熊熊燃烧的壁炉,只是一种情调而已。 Workshop一共进行了三天,时间是这样安排的: 第一天,上午到达,午饭后进行4个主题报告; 第二天,上午5个主题报告,下午自由活动,晚饭前一个小时的分组讨论; 第三天,上午4个主题报告,午饭后收拾行李,打扫卫生,返回。 关于主题报告,形式和我们常见的差不多,每人讲大约半个小时。感触颇深的是他们的讨论,极其热烈,每个人,无论是老师还是学生(都是硕士生和博士生),都积极地自信地发言,没人担心问的问题或提的意见太小儿科而不好意思发言,也没人武断地打断别人的发言来显示自己的权威;甚至从说话人的口气来判断,不知情的人根本分不出哪个是老师哪个是学生;大家都非常自信,每个人都是平等的。这样的讨论方式,与我之前所经历的workshop有着很大的区别。因为自己一直是个小人物,人微言轻,在一些听报告的场合很少发言,因为总担心自己提的问题太低级而被人嘲笑,或者被某个权威牛人毫不客气地打断。尽管我没有这样的遭遇,但我却看到过类似的情况,所以害怕了,不敢说话了。我们的权威太多,学术上有学霸,工作上有领导,小人物也只有缄默的份儿。 自由活动时间,教授和学生更是平等的,每个人都很天真、单纯。教授拉上滑雪车从山坡上冲下来,摔个嘴啃泥也毫不在乎;几个大人围在一起玩貌似比较小儿科的扔飞盘游戏也乐在其中,甚至为了接一个侧面飞来的飞盘而奋不顾身地整个人倒在积雪中。还有人带着专业的滑雪设施跑到更高的山坡上过瘾。除了我之外,每个人玩得都很放松,很随意。 第二天晚饭前一个小时的分组讨论,再次让我深有感触。 教授把大家分成三组,每组一个主题,分头讨论,达成共识,再拿到大家面前讨论。 三个主题分别是: Group A: What makes a good presentation? Group B: What makes a good paper? Group C: How best to write-up research/optimize process of writing paper? 我被分到A组,讨论如何做一个好报告。大家你一言我一语地发表自己的看法,从报告的结构、陈述的观点、片子的布局、演讲者的口气及肢体语言等几个方面分别罗列好与不好的方面。 讨论完之后,每个小组选一个代表在大家面前讲一讲,继续完善内容。Workshop之后的第二天,每个人都收到一份整理好的三个讨论主题的共识。仔细研读一遍,受益匪浅! ---------------------------------------------- 通往小木屋的路上,深深的积雪 林间小木屋 近看小木屋,还是好几层的楼房。楼下是厨房、餐厅、会议室;楼上是卧室。 厨房。进来时是空的,上面摆的东西都是大家背来的:) 壁炉 简易的会议室兼活动室,投影仪和电脑也是自带的。 夜色中的小木屋 自由活动时间,大家包裹严实走出户外 拉着滑雪车上坡 在没膝的积雪中投掷飞盘

我们该借鉴的WORKSHOP形式
热度 1 来自海洋的古生物 2009-6-15 22:47
在国外转悠,感觉他们workshop的形式比较值得我们借鉴。也许不符合国内的国情,但个人认为在一定情况下,至少在和国外同行交流的时候,适当采用这种形式,比在一起吃吃喝喝要有效地多。以下简单介绍一下最近来香港(尽管也属于国内,但香港更国际化一些)参加一个workshop,希望能对workshop在国内推广起到一点点作用。 5月初,香港大学XX教授给我邀请函,说希望我来香港参加一个海洋生物学方面的workshop,通过这次workshop联系大陆,香港,泰国,马来西亚,新加坡和南非的部分学者对西太平洋生物进行较大范围的合作交流。由于我本来就要6月底来香港,所以按照他的要求简单做了准备。 第一天 ,乘坐港龙航空的班机,来到香港,下飞机,顺利办理入境手续,(由于最近H1N1问题,要填写健康申请表),还是熟悉的Chueng Ming来接我,老头子胖了不少,和我倒是比较搭配,哈哈。搭车来到大学,已经晚上7点多了,阿明帮我把行李放到房间。萍姐告诉我说,冰箱里面有速食咖喱饭,饮料,牛奶,专门为这次workshop准备的,任何参加人员可以随便吃,没有什么接待的酒席,但是很自由,随便吃,吃完洗澡睡觉。吃饭时看到一个老头在外认真的吃速食咖喱饭,由于不是很熟悉就没有到招呼,后来才知道原来是个大牛。 第二天, 准备workshop材料,由于没有什么准备,在房间内刻苦准备。早上去餐厅自助吃早餐,咖啡,牛奶,果汁,面包,cheese,随便吃,简单而且随意。中午和昨天那个老头一起的意大利面,我们自己动手,也没人接待。吃完自己继续准备。聊天中才知道那个老头是这方面的绝对专家,顶级期刊的编辑,心理平衡很多,看到不是因为自己是小兵,人家不搭理,这样的大牛待遇一样。 第三天, 按照计划workshop开始,大家介绍自己当地的情况,每个人简单介绍一下,中间3次Breaks,大家可以随意谈,期间普通话,广东话,英语,泰语,马来语夹杂着,聊的不亦乐乎。中午吃饭很简单,从附近pizza店买的pizza,还有实验室的人做的一些饭菜,边吃边聊,简单而且隆重。晚上的饭菜更有意思,是教授自己亲自动身,CURRY BUFFET,还有一个来自印度的教授做的印度饭菜,感觉比大吃大喝好多了,气氛活跃而且可以尽量交流。 第四天 ,学习实验技术,为了能大家所做的工作有一定可比性,所以教授带领的小组将所有人能的实验技术,进行统一培训,大家可以自由发表意见,只要合理的就修改,很快实验技术搞定。晚上大家去饭店吃饭,不过这次是AA制。 总体来说,这样的workshop简单,有效,又没有给主办方太多的麻烦,希望大陆的学者能够借鉴一下,不要一来人酒喝得酩酊大醉,非要把对方灌醉才好,喝完还要去K歌什么的。为什么不简单些,实用些呢? PS:可能不符合国情,随便胡诌而已

好的捕鼠器-----涵盖全开发过程的一体化开发平台
jiyipeng 2009-3-6 21:18
以前的项目中, ABB 团队采用的开发步骤,系统工程师定义规格书,软件工程师根据规格书和自己的阐释编写软件,这个过程耗时而且易出错误,最初的概念和规格常常在执行中变形 ABB 开发团队要解决这个问题并且提高效率 基于模型的 MATLAB 给 ABB 提供了涵盖全开发过程的一体化开发平台。他们称之为优化开发过程控制。 ABB 使用 Simulink 为其他项目运行系统仿真。他们为他们电力电子控制器的开发环境增加了 Real-Time Workshop ,他们使用这一工具从他们的 Simulink 模型自动生成和下载控制器代码到控制器中去;滤波电流控制,电网同步,电网功率监测,有功无功功率计算,其他物理变量。工程师使用 SimPowerSystems 的系统仿真验证算法, Stateflow 使得 ABB 能够建模控制 序列和快速的保护,使用 Real-Time Workshop 他们能够从 Simulink models 上生成 ANSI C 代码;使用 Stateflow Coder 他们能够从他们的流程图上产生 C 代码,避免令人疲惫和耗时的从算法到源代码的手工编程。他们可以在控制器中直接使用 使用 Real-Time Workshop 的外部模式可以调试控制器中的软件。 ABB 能够通过 Simulink models 作为一个可执行的保证规格书和代码通过开发过程同步。参数可以在 PC 中改变和优化,代码可以自动生成。然后将它们通过 Ethernet 联接直接送到控制器中去, AC 800PEC 控制器作为牵引变换器的控制器投放到市场,该逆变器需要在高温和振动的条件下工作 好处: ( 1 ) Development time and costs reduced ( 2 ) Development process improved ( 3 ) Highly accurate code generated
