起死回生的ERP系统建设

2003年。迪信通最初上ERP系统时。面临着重重阻力。用吴欢的话来说．项目差点要死掉了。因为中国连锁业的大环境。并不是从规范开始的。而是从跑马圈地开始的。当时连锁业的标准．比如CI要统一、VI要统一、物流要统一。这些标准没有一样能达到的。当时的迪信通。连基本的采购平台都没有。差不多是各采各的。虽然有一个物流中心。其实也就是供货商。而且当时从总部采购的比例。甚至连20％都不到。

Multiproxy使用手册

使用代理的意义何在? 最早使用代理大概是中国互联网的发展造成的。很多网友还记得当年的163和169吧。那时有意分割互联网为相互独立的国内网和国际网。一些聪明的网友发现持用代理可以绕过这个限制。用169的帐号看163的内容。呵呵。无论从费用和内容上。此举都颇讨人喜欢,也是当年的讨论热潮之一。只怕声势不下后来的所谓超频。据我看来。加挂代理似乎最重要的功能就是加快速度和匿名性。这是目前代理存在的主要目的了。

A method of defuzzification based on the approach of areas' ratio

The new method of defuzzification of output parameters from the base of fuzzy rules for a Mamdani fuzzy controller is given in the paper. The peculiarity of the method is the usage of the universal equation for the area computation of the geometric shapes. During the realization of fuzzy inference linguistic terms, the structure changes from the triangular into a trapezoidal shape. That is why the universal equation is used. The method is limited and can be used only for the triangular and trapezoidal membership functions. Gaussian functions can also be used while modifying the proposed method. Traditional defuzzification models such as Middle of Maxima − MoM, First of Maxima − FoM, Last of Maxima − LoM, First of Suppport − FoS, Last of Support − LoS, Middle of Support − MoS, Center of Sums − CoS, Model of Height − MoH have a number of systematic errors: curse of dimensionality, partition of unity condition and absence of additivity. The above-mentioned methods can be seen as Center of Gravity − CoG, which has the same errors. These errors lead to the fact that accuracy of fuzzy systems decreases, because during the training root mean square error increases. One of the reasons that provokes the errors is that some of the activated fuzzy rules are excluded from the fuzzy inference. It is also possible to increase the accuracy of the fuzzy system through properties of continuity. The proposed method guarantees fulfilling of the property of continuity, as the intersection point of the adjustment linguistic terms equals 0.5 when a parametrized membership function is used. The causes of errors and a way to delete them are reviewed in the paper. The proposed method excludes errors which are inherent to the traditional and non- traditional models of defuzzification. Comparative analysis of the proposed method of defuzzification with traditional and non-traditional models shows its effectiveness.     

Schematic classification problems and their solution

The necessity arises in a variety of tasks to classify items on the basis of the presence of one of a number of criterial sets of co-related feature values. Such sets are called class characteristics. Because such classification problems require the identification of characteristics on the basis of limited training information, they entail a difficult search problem. Consideration of the differences between the theoretical models underlying characteristic and volume pattern generators suggests a schematic approach. Schemata, sets of commonly co-occuring features values, are probabilistic indicators of class membership whenever the characteristics are unknown but the characteristic model prevails. Formal and algorithmic solutions to the classification problem when exemplars are simple (consist only of M feature or attribute values) are described. The relevance of these procedures to problems involving general (relational) data structures is also indicated.     

Ethical and legal issues for writing researchers in an age of media convergence

With the convergence of digital media into ever-widening social and technological networks for creation and distribution, the contexts for writing and the study of writing and writers have certainly changed. Researchers must navigate a dense matrix of ethical and legal issues in all phases of research when studying the ever-changing processes and products of digital communications. In this article, I draw from numerous sources to articulate a few of the challenges facing digital writing researchers in this age of convergence, focusing on issues of representation (researcher, participant, third-party), issues of informed consent, and issues of copyright and fair use.     

Interface as Exordium: The Rhetoric of Interactivity

In this article, I outline how the interface of new media functions rhetorically as an exordium to engage users and to dispose them to persuasion. The modular, networked, and interactive nature of new media requires an interface: a central place of interaction for the technological, human, social, and cultural aspects of new media. I propose that the interface functions rhetorically through three modes of interactivity, including multi-directionality, manipulability, and presence. By understanding these modes of interactivity and how they function to create various degrees of interaction and engagement, we can begin to develop the analytic tools needed to increase critical awareness of the interface. A rhetorical understanding of the interface enables us and our students to see that the shape and design of the interface is not natural and inevitable. The design of the interface is a design of human experience and, as such, the interface becomes a locus of power. The modes of interactivity it deploys are capable of enabling empowerment and enacting rhetorical patterns of control.

New debates on learning support

Abstract In the present debate on knowledge management and multimedia support of human learning, the word 'mediation' (of conduct) is often used as a natural correlate and rough equivalent to the word 'mediatisation' (of information). It is suggested that the distinction between the two words points to a basic difference between two types of processes which are crucial to a much needed rethinking of the conception and design of humanmachine interaction (HCI).
A redefinition of the 'appropriateness' of media support as the quality of the help to people's self-help rather than of direct control of their behaviour is proposed. Such a redefinition implies a radical shift of paradigm allowing for approaches to human learning as a cognitive activity in its own right. Another view of technological mediation is advocated, in keeping with some recent developments in HCI.

HUYGENS' PRINCIPLE,PHYSICS AND COMPUTERS

We discuss the emergence of topology from a consideration of set extensions in General Systems Theory. Boundaries arise in a natural way, separating independent elements or regions of the system. Our aim is a unification of Etter theory, Kron's method of Tearing and Jessel's formulation of Huygens' Principle. This should make explicit the equivalence between the objective, structural, holographic and the subjective, relative definitions of information, sought in Bowden (1994b), reprinted in this Special Issue. It connects the abstract generalisations of Schrodinger's equation and Bom's rule derived in probabilistic Etter theory with the real world of electrical and other physical phenomena in General Physical Systems Theory. This paper can be considered as a continuation of Bowden (1990; 1994a) and as a response to Bowden (1994b), reprinted in this issue.

We review the ideas behind Kron's Method of Tearing and Jessel's Principle of Secondary sources (both special cases of the above theory) and their equivalence. We follow Hiley's argument in Hiley (1996) to show how Schrodinger's equation can be thought of as specifying the evolution of (a series of) tearings in continuous space. These can be shown on a commutative diagram as a series of similarity transforms. We compare this with Etter's derivation (Etter, 1998). We describe briefly a recently published derivation of Maxwell's equations from a non-commutative algebra and show how they fit onto a related commutative diagram. Finally we make some comments on applications of the general theory to computer systems. This paper is a series of vignettes of work in progress. It is designed to point the direction of work to come in Constructive Physics.     

An approach to the synthesis of fuzzy stabilization systems with a priori unknown model of an object

A method of synthesis of fuzzy stabilization systems for a broad class of dynamic objects under the assumption that the mathematical model of the object is not known a priori is proposed. The control is formulated in the form of a proportional law of adjustment as a function of a macro-variable; the square of the Euclidean norm of the phase variables is adopted as the macro-variable. An analogous variable characterizes the distance of the object from the equilibrium position. Despite the simplicity of the control law, its sign remains constant due to the fact that the macro-variable is positive-definite over the entire phase space. The switching times of the signals are determined by fuzzy identification of the system’s dynamic modes on the basis of measurement of the derivatives of the macro-variable.
