Using the CERN generic Windows infrastructure in a specific control environment

CERN has a large Windows 95/NT infrastructure with more than 3500 PCs connected that is used as one of the main information services for the laboratory. This infrastructure is used for a wide set of services, including Office Automation, Computing Aided Engineering, Calculations, Software Development, and ... controls. This paper will describe the CERN generic infrastructure for Windows 95 and Windows NT and then give several examples of PC control applications and future directions. The implementation of an object oriented device server based on Windows NT and ActiveX in the CERN ISOLDE-REX experiment will be reported

Multimedia presentation design using data flow diagrams

[[abstract]]Structured analysis/design methodology has been used in software development for many years. We propose a revised data flow diagram technique and system based on the structured analysis methodology. The system allows a multimedia presentation designer to stepwise refine his/her presentation toward an interactive Petri net, which defines the temporal behaviour of the presentation. The generated presentation can mutate itself at runtime. Therefore, the presentation can act according to the audience's responses. The system is implemented in Visual C++ and Visual Basic running under Windows 95/NT[[conferencetype]]國際[[conferencedate]]19971028~19971031[[iscallforpapers]]Y[[conferencelocation]]Beijing, Chin

Field drainage management

Presented at the 2002 USCID/EWRI conference, Energy, climate, environment and water - issues and opportunities for irrigation and drainage on July 9-12 in San Luis Obispo, California.Includes bibliographical references.The Colorado State University Irrigation and Drainage model (CSUID) is a decision support system (DSS) that helps design and/or manage irrigation and drainage systems, which maintain crop productivity while controlling drainage return flows. CSUID includes components for irrigation scheduling; root growth calculations; flow and transport in unsaturated and saturated zones; drain discharge; and crop yield estimates. The DSS runs on a PC with Windows 95/NT. Data for the model is currently being collected from four fields in Colorado's Arkansas River Basin

Shared teaching with multimedia‐enhanced video‐conferencing

Video‐conferencing was used to share a short series of lectures between several universities. A high bandwidth network (155Mbit/s) permitted near broadcast TV quality video to be combined with fully mixed, high‐quality audio. The lectures were supported by visual aids made available using Microsoft NetMeeting to provide multipoint, shared applications. NetMeeting is shown to be a stable and effective platform for distributing multimedia material at a much higher resolution than is possible using the video signals common in most video‐conference lectures, although care must be taken when constructing animated material

Visual communication in urban planning and urban design

This report documents the current status of visual communication in urban design and planning. Visual communication is examined through discussion of standalone and network media, specifically concentrating on visualisation on the World Wide Web(WWW).Firstly, we examine the use of Solid and Geometric Modelling for visualising urban planning and urban design. This report documents and compares examples of the use of Virtual Reality Modelling Language (VRML) and proprietary WWW based Virtual Reality modelling software. Examples include the modelling of Bath and Glasgow using both VRML 1.0 and 2.0. A review is carried out on the use of Virtual Worldsand their role in visualising urban form within multi-user environments. The use of Virtual Worlds is developed into a case study of the possibilities and limitations of Virtual Internet Design Arenas (ViDAs), an initiative undertaken at the Centre for Advanced Spatial Analysis, University College London. The use of Virtual Worlds and their development towards ViDAs is seen as one of the most important developments in visual communication for urban planning and urban design since the development plan.Secondly, photorealistic media in the process of communicating plans is examined.The process of creating photorealistic media is documented, examples of the Virtual Streetscape and Wired Whitehall Virtual Urban Interface System are provided. The conclusion is drawn that although the use of photo-realistic media on the WWW provides a way to visually communicate planning information, its use is limited. The merging of photorealistic media and solid geometric modelling is reviewed in the creation of Augmented Reality. Augmented Reality is seen to provide an important step forward in the ability to quickly and easily visualise urban planning and urban design information.Thirdly, the role of visual communication of planning data through GIS is examined interms of desktop, three dimensional and Internet based GIS systems. The evolution to Internet GIS is seen as a critical component in the development of virtual cities which will allow urban planners and urban designers to visualise and model the complexity of the built environment in networked virtual reality.Finally a viewpoint is put forward of the Virtual City, linking Internet GIS with photorealistic multi-user Virtual Worlds. At present there are constraints on how far virtual cities can be developed, but a view is provided on how these networked virtual worlds are developing to aid visual communication in urban planning and urban design
