面向计算机集群系统的FP-Growth算法的并行计算

FP-Growth是频繁模式挖掘的经典算法，能够在不产生候选集的情况下生成所有的频繁模式，效率与Apriori算法相比有巨大提高，然而FP—Growth算法在挖掘频繁模式过程中需要递归构建大量的条件FP—tree，并分别针对这些条件FP—tree进行挖掘，时间及空间效率不高，在实际应用中存在很大局限性。计算机集群是由多台普通计算机设备通过特定方式结合在一起构成的并行处理系统，属于分布式计算环境，具有计算能力强大、性价比高、灵活等优势。本文提出一种面向计算机集群的并行挖掘算法Gridify FP-Growth，该算法以FP—Growth为基础，通过任务划分的形式，将计算任务分配到计算机集群中各个计算节点上执行，充分利用各个节，最的计算资源，最后汇总各节点的计算结果。实验证明GridifyFP—Growth算法不会牺牲计算的准确性，并可以大幅度缩短计算时间，有效缓解计算大规模数据库时的内存压力。

粒子群自进化算法求解物流装箱问题

为了解决当今物流行业中装载货物类型为强异构的情况,提高装载填充率和效率,提出了一种求解三维装箱问题的元启发式算法——粒子群自进化算法。算法包含两部分：极限点构造启发式算法和粒子群自进化规则。极限点构造启发式算法引入了极限点的概念,利用新的极值点思想推导出了三维装箱问题的启发式算法。粒子群自进化规则提出了在货物装载序列中表示粒子的方法,推导了粒子间交叉、变异算子,在极限点构造启发式算法的基础上不断迭代进化完成货物的装载。通过不同结果的比对,证明该算法显著提高了物流装载的空间利用率,强异构货物的平均装载率达到了85%,验证了算法在强异构货物下的有效性与优越性,并给出了货物装载的三维模型。由于实际测试集的缺少,分别为机腹仓装载类和集装板类模型提出了实例生成器,通过生成器的测试集验证了算法在实际应用中的紧凑性、实用性和快捷性。

Rules of the game: constructing norms of influence,subordination and constraint in IT planning

This paper examines how norms develop and influence the planning of technological and organizational change. A case study highlights the influences of a broadly held management innovation as it is introduced into an existing organizational culture, demonstrating how norms play a role in attempts to introduce technical and management innovations. In the case, three sources of normative structuring—business process re-engineering, the consultant, and the target organization's business environment—converged to create new rules defining how to conceptualize the problem space, the appropriate ways to approach problems, who had actionable authority and how ideas were to be expressed. The emergent normative context trapped the group in a malfunctioning process and eliminated opportunities to question the process or to suggest alternative directions. This case highlights how analyzing normative systems holds promise to improve scholarly understanding of organizational technologies and to refine managerial tools for technological and organizational innovation.     

The hierarchical terminology technique: a method to address terminology inconsistency

A review of prior research in the computer-supported cooperative work (CSCW) field found that the terminology and definitions used by researchers were inconsistent, with some terms being defined differently but then used interchangeably. Inconsistency in the use of terminology makes it difficult to determine what technology is being used in the research and where a research study fits into the research field. Authors in many fields describe the problem of inconsistent terminology use. A suitable method for identifying inconsistencies and structuring terminology for greater clarity of terminology use in a given research field was not identified. This paper presents a new method, the hierarchical terminology technique (HTT), which is a form of qualitative content analysis process that extends the idea of concept mapping. HTT was developed for this research problem to structure a hierarchy of terms to expose the relationship between the terms. This technique includes terminology identification, analysis and presentation to show the scope of the research field, and to present terminology and definitions to improve consistency. This technique could be used in other fields of study.

Growing and reproducing particles evolving through space and time

In this paper we develop a spatially explicit marked point process model to generate spatial patterns of reproducing and moving cells evolving through continuous time. In this context, marked points (i.e. cells) can divide and move as a result of (a) their own growth and division motions, and (b) the division motions and the growth of their touching neighbours. To illustrate such dynamics we present several simulated examples. Our results suggest that by replacing the mathematically convenient growth and interaction functions by others more suited to mimic realistic cell reproduction dynamics, this model may provide a modelling framework to simulate cell aggregate (i.e. tissue) dynamics. Moreover, adding movement to dividing and growing points opens up new areas of application as well as new theoretical problems such as the analysis and generation of dense packing of discs (or spheres).

Abstract

Drawing on Parkin's [Marxism and class theory: A bourgeois critique. London: Tavistock Publications] concept of dual closure, this paper examines the attempt to secure the regulation of the accountancy profession in post-unification Italy. The state's establishment of a class of ‘expert accountants’ in 1865 represented an imperfect closure of the profession. In consequence, a chain of closure attempts ensued. These ventures involved shifting constructions of dominant and subordinate occupational groups and the deployment of diverse strategies to achieve usurpationary and exclusionary forms of closure. The study reveals that the achievement of state regulation of the profession in 1906 reflected the successful pursuit of usurpationary closure by a subordinated group within the accountancy field. However, it also points to the failure of the profession's efforts to make incursions into the jurisdictions of higher status occupations, especially lawyers, who wielded considerable sociopolitical power in newly unified Italy. Consistent with the findings of previous studies, the paper confirms the complexity and uncertain outcomes of closure projects in the accountancy profession.     

Cloud manufacturing: a new manufacturing paradigm

Combining with the emerged technologies such as cloud computing, the Internet of things, service-oriented technologies and high performance computing, a new manufacturing paradigm – cloud manufacturing (CMfg) – for solving the bottlenecks in the informatisation development and manufacturing applications is introduced. The concept of CMfg, including its architecture, typical characteristics and the key technologies for implementing a CMfg service platform, is discussed. Three core components for constructing a CMfg system, i.e. CMfg resources, manufacturing cloud service and manufacturing cloud are studied, and the constructing method for manufacturing cloud is investigated. Finally, a prototype of CMfg and the existing related works conducted by the authors' group on CMfg are briefly presented.
