Abstract

This paper describes the original integration of three concepts (finite elements, geoparametric transformations, and HyperMaps) and their application to the management of the water network in the region of Lausanne, Switzerland. The finite element method lets us simulate network flows and two or three dimensional fields. Using this simulation method, propagation of a pollutant or chlorine concentration can be followed through the network. The transient flow can be stored in Quick Time format for later replay, making it a very user friendly analysis tool. To process very large graphical data, the Swiss Federal Institute of Technology together with BSI developed a multiprocessor-multidisk image server named GigaView. The GigaView is an intelligent disk array for desktop systems and workstations. It includes transputers connected to each disk node, and supports local image processing such as zooming and rotation. The HyperBird application running on a Macintosh platform and a GigaView connected through a SCSI bus demonstrate the feasibility of this approach

Desktop environment

In computing, a desktop environment (DE) is an implementation of the desktop metaphor made of a bundle of programs running on top of a computer operating system that share a common graphical user interface (GUI), sometimes described as a graphical shell. The desktop environment was seen mostly on personal computers until the rise of mobile computing. Desktop GUIs help the user to easily access and edit files, while they usually do not provide access to all of the features found in the underlying operating system.

Finite element method

The finite element method (FEM) is a popular method for numerically solving differential equations arising in engineering and mathematical modeling. Typical problem areas of interest include the traditional fields of structural analysis, heat transfer, fluid flow, mass transport, and electromagnetic potential. The FEM is a general numerical method for solving partial differential equations in two or three space variables (i.e., some boundary value problems).

Window manager

A window manager is system software that controls the placement and appearance of windows within a windowing system in a graphical user interface. Most window managers are designed to help provide a desktop environment. They work in conjunction with the underlying graphical system that provides required functionality—support for graphics hardware, pointing devices, and a keyboard—and are often written and created using a widget toolkit. Few window managers are designed with a clear distinction between the windowing system and the window manager.
