This paper describes the concept of augmented reality, the process of drawing virtual images over the real world using a head mounted display. Using wearable computers, it is possible to take augmented reality software outdoors and visualise data that only exists in a computer. The paper discusses all concepts in detail, and the hardware used to build the system, explaining the various componen...

The Scythe Statistical Library is an open source C++ library for statistical computation. It includes a suite of matrix manipulation functions, a suite of pseudo-random number generators, and a suite of numerical optimization routines. Programs written using Scythe are generally much faster than those written in commonly used interpreted languages, such as R and MATLAB; and can be compiled on a...

This paper presents a probabilistic approach based on collisions to assess the storage capacity of RAM-based neural networks. The analysis at neuron level provides the basis for evaluation of storage capacity in the architectures. The approach is tested in the GNU and pyramid networks. In the GNU as an auto-associative memory, the theoretical results t well with Braga's experimental data and ar...

This paper explains the goals and current status of the Open Robot Control Software project (Orocos). This project builds a software framework for generic control problems, with robot control as first target. The first development in the project was the infrastructure for an application-independent control “core.” This core can run in hard real-time (on RTAI and RT-Linux), but also in “user spa...

In the paper an option of scientific information communication link, based on SDR technology, for “Chibis–AI” spacecraft is considered. The program package GNU Radio 3.10 has been used. To satisfy technical requirements data rate new additional blocks have developed. Engineering model channels produced. Correspondence measured specifications show.

Although programs convey an unambiguous meaning, the grammars used in practice to describe their syntax are often ambiguous, and completed with disambiguation rules. Whether these rules achieve to the removal of all the ambiguities while preserving the original intended language can be difficult to ensure. We present an experimental ambiguity detection tool for GNU Bison, and illustrate how it ...

Der Beitrag zählt zunächst einige Eigenschaften von Mailing-Listen sowohl technischer als auch sozialer Natur auf. Er vergleicht das in Mailing-Listen verbreitet entstehende Konsensmodell mit einigen Aspekten von Demokratie und schließt mit der Frage, wozu andere Tools eigentlich notwendig sind. 1 Eigenschaften von Mailing-Listen In vielen virtuellen Projekten sind Mailing-Listen das zentrale M...
