Network interface unit "Artemis product dissemination by E-mail"

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...

Telescience and image processing for PODI: An analysis and a proposal for a simulation set-up

CADISS: a multi-processor system for image compression/decompression on board scientific satellites

Project CADISS has produced an elegant breadboard of a system for compression (and -if required- decompression) of signals generated by imaging sensors on-board scientific satellites. The performance, specifications and physical characteristics of CADISS are the result of trade-offs on function (algorithms), technology, through-put speed and...

An evaluation of data compression algorithms

Non-specialist users of data compression often encounter difficulties with the selection of an algorithm, suited for their application. This report tries to facilitate this task by providing the necessary information about the algorithms. Four established, at the National Aerospace Laboratory available algorithms were selected for this study: -...

Data compression in computational fluid dynamics

Computations in numerical fluid dynamics create large sets of data. Transmission of these datasets requires a high speed communication link or, alternatively, the use of data compression techniques. This report describes the results of a study to the applicability of data compression techniques. An algorithm is designed that yields favourable...
