BASKETBALL ScORING IN NBA GAMES:AN EXAMPLE OF cOMPLEXITY

Journal of Systems Science & complexity 2013年第1期26卷 94-103页

Scoring in a basketball game is a highly dynamic, non-linear process. NBA teams try to be more and more competitive each season. For instance, they incorporate into their rosters the best players in the world. This and other mechanisms concur to make the scoring process in NBA games exciting and rarely predictable. This paper is to study the behavior of timing and scoring in basketball gaines. The authors analyze all the games in five NBA regular seasons （2005-06, 2006-07, 2007-08, 2008-09, 2009-10）, for a total of 6150 games. Scoring does not behave uniformly; therefore, the authors also analyze the distributions of the differences in points in the basketball games. To further analyze the behavior of the tail of the distribution, the authors also carry out a semilog-plot and a log-log plot to verify whether this trend approaches a Poisson distribution or a PL. This paper reveals different areas of behavior related to the score, with specific instances of time that could be considered tipping points of the game. The presence of these critical points suggests that there are phase transitions where the dynamic scoring of the games varies significantly.

Software Project Effort Estimation Based on Multiple Parametric Models Generated Through Data clustering

引用

Journal of computer Science & Technology 2007年第3期22卷 371-378页

作者： juan J.cuadrado Gallego Daniel Rodríguez Miguel Angel Sicilia Miguel Garre Rubio Angel garcía crespo Department of computer Science The University of Alcalá AlcaláSpain Department of computer Science carlos Ⅲ University.Madrid Spain

Parametric software effort estimation models usually consists of only a single mathematical relationship. With the advent of software repositories containing data from heterogeneous projects, these types of models suffer from poor adjustment and predictive accuracy. One possible way to alleviate this problem is the use of a set of mathematical equations obtained through dividing of the historical project datasets according to different parameters into subdatasets called partitions. In turn, partitions are divided into clusters that serve as a tool for more accurate models. In this paper, we describe the process, tool and results of such approach through a case study using a publicly available repository, ISBSG. Results suggest the adequacy of the technique as an extension of existing single-expression models without making the estimation process much more complex that uses a single estimation model. A tool to support the process is also presented. Keywords software engineering, software measurement, effort estimation, clustering

APPLYING PROcESS MINING APPROAcH TO SUPPORT THE VERIFIcATION OF A MULTI-AGENT SYSTEM

引用

Journal of Systems Science and Systems Engineering 2010年第2期19卷 131-149页

作者： c.OU-YANG Yeh-chun juan Depart.of Industrial Management National Taiwan University of Science and Technology Depart.of Industrial Engineering and Management Ming Chi University of Technology

Using agent development tools to construct an agent-based system is a well applied approach. However, the development tools usually do not have the function to check the feasibility about the workflow of the agent system during it implementation stage. Therefore, to develop an evaluation approach to analyze the feasibility of a developing agent system such that the improper workflow of an agent system can be found in the early design stage is a necessary task to reduce the risk of implementation. In this research, a Petri Net （PN） based three-stage evaluation approach was developed. In the conceptual stage, the pitfall of the current agent system developing process was examined and an improvement analysis process was specified. Then, in the system design stage, an evaluation approach which extracted the process log file from a developing agent system into a PN model in terms of a process mining approach-or algorithm was proposed. This model was simulated in a PN simulation package. The agent system performance was evaluated in terms of analyzing the deadlock phenomena of the PN model. Finally, in the implementation stage, the proposed concept was implemented by using an agent developing tool JADE and a PN simulation tool cPN. An agent-based robotic assembly system was used to examine the possible deadlock of the agent system.

众筹作为最受欢迎的互联网金融产品之一,受到工业界和学术界的广泛关注。基于现实背景,本文建立了两阶段众筹模型,研究了消费者估值不确定下消费者的策略性选择行为及其对众筹定价策略的影响。结论表明,若消费者参与众筹的额外效用较低,消费者估值不确定会造成“搭便车”现象,导致最优众筹价格不是关于项目所需资金的单增函数。当项目所需资金较低或较高时,发起人应该设置较高的众筹价格,否则应该降低价格以激励更多的消费者参与众筹。通过对比传统销售模式,本文揭示了发起人可以利用消费者估值不确定性及众筹的预售机制增加销量或边际收益以提升利润。进一步,本文证明了退款机制可以有效增加消费者参与众筹的意愿,从而提高众筹的可行域。最后,本文将基本模型拓展到更加一般的情形,研究发现众筹市场大小、项目运作风险和生产能力均对最优定价决策有不可忽视的影响。

Opposite fates of fructose in the development of metabolic syndrome

引用

World Journal of Gastroenterology 2012年第33期18卷 4478-4480页

作者： Marta Alegret juan c Laguna Department of Pharmacology and Therapeutic chemistry School of Pharmacy University ofBarcelona Institute of Biomedicine 08028 Barcelona Spain Biomedical Network Researchcentre Physiopathology of Obesity and Nutrition (CIBERobn)08028 Barcelona Spain

This short review comments on the recently published work of Ishimoto et al regarding the opposing effects of fructokinase c and A isoforms on fructoseinduced metabolic syndrome in mice. The framework for the commentary is the preexisting background of epidemiological and experimental data regarding the association between ingestion of fructose, as present in sweetened beverages, and the development of metabolic syndrome. The work of Ishimoto et al clearly confirms the negative effect of fructose on lipid and glucose metabolism, independently from the amount of energy provided by the ingested sugar. It also confirms the absolute requirement of liver fructose metabolism, driven by fructokinase activity, in order to develop the full spectrum of metabolic syndrome alterations.
