Despite the enormous media coverage that the issue of year 2000 (Y2K) readiness has received in recent months, the focus of that coverage has been restricted almost exclusively to technological aspects. Non-technical issues have tended to be either ignored completely or given very little attention. Most importantly, not much is known about the organisational processes of preparing to face this ...

This document is intended for people who want to “be aware” of some of the mechanisms underlying the JPEG2000 image compression standard [2]. While writing this tutorial my objective was to give to the reader the feeling of what goes on when compressing images with JPEG2000 . Hence, this tutorial should be regarded as introductory material which requires further reading to reach a deeper unders...

In this paper, we investigate the error resilience properties of JPEG2000. Through a careful analysis of the structure of JPEG2000 codestreams, we identify the dependencies among coding passes of a codeblock. In our analysis, we consider the effects of mode variations provided by the standard for low-memory, low-complexity implementations. The proposed methods are derived using the existing dep...

This manual is only partially complete and is a work in progress. A completed manual will be available by January 1,2000. Cluster and TreeView are Y2K Compliant because they are oblivious of date and time.

For the first time, a complete wireless and mobile emergency TeleOrthoPaedics system with field trials and expert opinion is presented. The system enables doctors in a remote area to obtain a second opinion from doctors in the hospital using secured wireless telecommunication networks. Doctors can exchange securely medical images and video as well as other important data, and thus perform remot...

Invasive alien plants have severe impacts on biodiversity and ecosystem services worldwide. To assess the invasion of Solanum elaeagnifolium Cav. (a major invasive plant; Solanaceae) in Greek protected areas (PAs), we conducted an extensive drive-by survey across country crossing half Natura 2000 sites. The occurrence data were then linked GIS with (i) boundaries sites, (ii) mapped habitat type...

The year 2000 countdown provided a uniquely visible instance of spending on information technology by U.S. companies. With public attention riveted on potential Y2K malfunctions, managers were forced to evaluate their IT and make decisions whether to modify or replace existing systems. In the aftermath of Y2K, critics charged that the problem was overblown and that companies overspent on IT. In...

In this paper we describe a GBIF/TDWG-funded project in which LSIDs have been deployed in the Catalogue of Life’s Annual and Dynamic Checklist products as a means of identifying species and higher taxa in these large species catalogues. We look at the technical infrastructure requirements and topology for the LSID resolution process and characteristics of the RDF (Resource Description Framework...
