Multidimensional XML (MXML) is an extension of XML that incorporates dimensions in order to represent in an elegant and concise way context-dependent data, that is, data which can exhibit different variations in value or structure (e.g. that can exist in different languages or various degrees of detail). We show that MXML dimensions can be used to express time and associate it with XML elements and attributes. We discuss the properties of the time domain and the features of MXML which are necessary in order to represent time, and give key points that motivate further investigation on the use of MXML for representing time-dependent data.

There are numerous facts in our world that must be taught and learned every day. Conceptual learning can promote both processes. However, in spite of the performance of modern technologies, computer aided tools for conceptual learning are still rarely used in everyday practice. The article presents and discusses the animations of cardiac diseases and their surgical treatments. Such animations enable the students of medicine to apply the principles of conceptual and mastery learning, improve their problem solving skills, and become independent life-long learners.

A core module for the computer science and computing degree courses at the University of North London provided a vehicle for developing an innovative approach in teaching and learning. It served as a means of bridging the gap between real-world business information systems (BIS) development practice and that which is normally simulated in academia. We also show how students can be encouraged to be proactive in creating their own real-world learning experience within an academic environment.

To simplify the usage of a computer network as a virtual parallel machine, as well as to introduce the opportunity of distributed parallel computing to Visual Basic users, a DCOM-based software infrastructure is proposed in this article. This infrastructure is based on a master-slave model. It sends a broadcast call over a subnet as an invitation for cooperation, automatically distributes new program versions, and manages the unfinished jobs on the slave machines. As a test application, a simple solution of the traveling salesman problem is implemented.

The paper examines the current state of Internet privacy. We assess the needs of UK Internet users in terms of online privacy protection, and determine the extent to which current privacy practices were satisfying those needs. Our work examines: (a) Internet users' attitudes towards online privacy; (b) 50 Web sites' privacy policies and practices and (c) existing privacy protection for users such as legislation and technological tools. The survey reveals a high level of concerns amongst Internet users related to their privacy in terms of: (i) personally identifying information that they provide to Web sites, (ii) the information that Web sites collect through the use of cookies and IP addresses and (iii) the information derived by tracking users' online activities.

Historically (1984) a group of researchers at Hiroshima University, Japan, considered how to bridge the chasm between high level programming languages and the human level by introducing a purely graphical language (called visual) which would be able to express both data and control structures so that real programs could be drawn. This basic idea stemmed from a natural extension of the direct manipulation interface where icons are selected, dragged and placed near/on top of other icons so as to express actions that may entail processes of variable complexity. The concept of usability, in terms of human acceptance and satisfaction of the visual language, was introduced so as to enable a human-centered evaluation of the implemented prototypes. At the same time, research has also considered graphical layout on the screen, a number of different visualization strategies, the user task analysis, user modeling, icon design according to different user cultures and background, a definition of state within an interactive system, and many others as may be seen by the growing number of meetings on all these subjects. The paper discusses the concepts and claims of visual languages.

We introduce a new approach to evaluate the effects of branch and value prediction. So far, all the papers published in this area used trace-driven or execution-driven simulation in order to obtain an estimation of the potential to use these techniques. We introduce an analytical model based on fluid stochastic Petri nets (FSPNs). This model is used to capture the dynamic behavior of an ILP processor with aggressive use of prediction techniques and speculative execution. We define the FSPN model and derive the state equations for the underlying stochastic process. Our implementation-independent approach confirms recently published results about control and data speculation and reveals considerable potential for further research using numerical solution of systems of partial differential equations.

Producers have confronted customers' requirements on market and make to order production. Key characteristics of concurrent production strategy are flexibility, and short production cycle and the basic goals that have to be managed are dates, costs and quality. The production cycle has to be decreased if producers want to satisfy due date according to contract. An optimisation planning and monitoring algorithm for single production that has been implemented in a management information system (MIS) is presented.

In cast-moulding, the study of sensitivity to the change of a chosen projecting parameter allows the constructor to draw up the optimum project. In this paper, an algorithm for studying sensitivity, considering the thermal diffusivity coefficient of the moulding mass is described, We consider an area /spl Omega/ consisting of two sub-areas /spl Omega//sub 1/ and /spl Omega//sub 2/. We assume that the area /spl Omega//sub 1/ is filled with cooling metal, while /spl Omega//sub 2/ is filled with moulding sand. From our mathematical description, the system circumscribing receptivity is overtly dependant on temperature. This results in the necessity of reckoning sensitivity at the considered moment of time.
