ARTEMIS (Africa Real-Time Environmental Monitoring Information System) is used by FAQ (Food and Agriculture Organisation of the United Nations) to support both its internal prograimnes on early warning and food security and desert locust control as well as developing countries in Africa by processing image information originating from the...

Multimedia tele-education - PC based real-time narrowband applications

After surveying tele-education systems and technology, this study describes the design of a tele-education system which is particularly suitable for the extension of the educational facilities of universities to remote communities. The study is focused on the application of third-world small-scale institutes like the University of the...

SPINE: Software platform for computer supported co-operative work in heterogenous computer and software environments

In development of High Performance Computing and Networking (HPCN) for simulation applications several targets have to be realized. It is recpiired to maximize not only computational speed but also to maximize applicability in engineering environments. For applications in which HPCN-based simulations are economically and technically necessary...

Introduction to possible means of experiment operations on the space station

The present plans for space stations are evolutionary developments from Skylab, ASTP, Spacelab, and recently, MIR. Other forbears can be identified as well, and it is instructive to compare current designs with the drawings that appeared in magazines around 1950, when spaceflight first appeared feasible. The space station that is taken as the...

De netwerkvoorzieningen op het NLR ten behoeve van het supercomputergebruik - Data communication network at NLR for supercomputer usage

For the development of methods for aerospace research and development at NLR large computer facilities are available, among which a NEC SX-2 supercomputer, a Control Data Cyber 180-855 mainframe and various minicomputers and workstation. To provide users a good access to the various systems a high speed computer network is defined, existing of a...

Technical concept for datamanagement systems of flow solvers using BOLA as an example

In the development of mathematical simulation methods for engineering processes, it is essential to validate the mathematical models. Its results must be compared with results from other calculation methods or measurements. This is especially true in computational fluid dynamics (CFD). It is essential that an engineer developing mathematical...

Voorontwerp methodenbestandssysteem - Preliminary design method base system

The informatics policy at NLR is focussed on providing an infrastructure for the development of information systems. A new component in the infrastructure is the method base system, designed to support the management and use of algorithm implemented in programs. The preliminary design analyses the functions of the method base system and...

Gedrags- / prestatiekarakteristieken van informatievoorziening - Performance characteristics for information supply

Technical/industrial automation focusses on the primary business processes, such as design and fabrication of products. In view of the importance extensive studies are required to demonstrate the feasibility and to motivates various choices. Moreover stringent requirements for the information supply will be defined. The National Aerospace...
