Definition Of

MechXML is an XML-based language aimed at describing multibody systems and their simulations (see a more detailed description in [1]). With the appropriate easy-to-build parsers, a data file written in this language can be executed with little or no modification at all in many commercial and research-oriented programs. The purpose of this paper is twofold: to introduce briefly this language and to describe with more detail the new developments that allow the definition of continuous control subsystems. The definition of controls is based on block diagrams. The user defined functions are a general way to customize multibody simulation software so as to enable it to deal with arbitrary forces and constraints. They are described here because they can be used to describe the actions of control systems, too. At the end, a file written according to the rules of MechXML is parsed and run in two programs as different as MSC.ADAMS and SimMechanics.

Mesh Models

To achieve effective 3D shape retrieval, there is a crucial need for efficient shape matching methods. This paper introduces a new method for 3D shape matching, which uses a simplified octree representation of 3D mesh models. The simplified octree representation was developed to improve time and space efficiency over prior representations. The proposed method also stores octree information in extensible markup language format, rather than in a new proprietary data file type, to facilitate comparing models over the Internet.

Long Term Preservation

Data warehouses are used in many application domains, and there is no established method for their preservation. A data warehouse can be implemented in multidimensional structures or in relational databases that represent the dimensional model concepts in the relational model. The focus of this work is on describing the dimensional model of a data warehouse and migrating it to an XML model, in order to achieve a long-term preservation format. This chapter presents the definition of the XML structure that extends the SIARD format used for the description and archive of relational databases, enriching it with a layer of metadata for the data warehouse components. Data Warehouse Extensible Markup Language (DWXML) is the XML language proposed to describe the data warehouse. An application that combines the SIARD format and the DWXML metadata layer supports the XML language and helps to acquire the relevant metadata for the warehouse and to build the archival format.

Enterprise Information, especially in the manufacturing process, material information management is a key technology. If some companies or individuals need to communicate or exchange the material information between them and they use incompatible systems, what style of data file will be chosen to exchange? Converting the data to XML can greatly reduce this complexity and create data that can be read by many different types of applications. This paper describes basic principle about XML(Extensible Markup Language) and its security, then analyzes an application of its security.

Limit Access

An important element of transformational government is improving the access and use of government information. Effective use of government information requires government to move beyond traditional proprietary document formats because these formats limit access and use of information stored digitally. In this chapter, we show how document formats based on open standards and the Extensible Markup Language (XML) can revitalize citizens’ access and use of government information. We also offer an improved definition of open standards to assist governments in selecting which document formats to adopt. A critical part of this new definition is an emphasis on multiple implementations of an open standard, which is also known as running code.

Many of the currently available commercial multibody systems simulation packages are limited to rigid bodies linked by joints. Accurate dynamic analysis of multibody systems might require consideration of the flexibility of some components. Finite element analysis is generally the method of choice for structural dynamic analysis. Implementation of a fully featured reliable finite element capability within well-established commercial multibody systems software is not an easy task. A practical solution is to interface commercial finite element analysis software with commercial multibody systems software. This paper describes the theory and implementation aspects of such an interface. The interface is based on the Craig-Bampton method of component mode synthesis. The power of this technique is that it presents customers of commercial multibody simulation software with a practical and reliable tool to address component flexibility. The technique has been implemented to interface two major commercial simulation packages. Two practical applications, a flexible connecting rod and a flexible hard disk drive head-stack assembly, are discussed.

Representation Of Knowledge

AbstractWhen dealing with biological organisms, one has to take into account some peculiarities which significantly affect the representation of knowledge about them. These are complemented by the limitations in the representation of propositional knowledge, i. e. the majority of clinical knowledge, by artificial agents. Thus, the opportunities to automate the management of clinical knowledge are widely restricted to closed contexts and to procedural knowledge. Therefore, in dynamic and complex real-world settings such as health care provision to HIV-infected patients human and artificial agents must collaborate in order to optimize the time/quality antinomy of services provided. If applied to the implementation level, the overall requirement ensues that the language used to model clinical contexts should be both human- and machine-interpretable. The eXtensible Markup Language (XML), which is used to develop an electronic study form, is evaluated against this requirement, and its contribution to collaboration of human and artificial agents in the management of clinical knowledge is analyzed.
