This paper describes an open-ended and collaborative learning environment in WWW. In the environment called SharlokII, the learners provide and share individual knowledge and other knowledge on the WWW and discuss about them. This paper focuses on knowledge awareness map and its design, implementation and evaluation. The map visualizes the relationship between the shared knowledge and the curre...

Current mapping algorithms using Consistent Pose Estimation (CPE) algorithms can successfully map areas of 10 square meters, using thousands of poses. However, the computation to construct the map grows as O(n log n), so larger maps get increasingly difficult to build. We present an abstraction method for postponing the growth in computation. This method solves a much smaller problem in the spa...

The mathematical semiconductor device model, consisting of the potential equation and the current continuity subsystem for the carriers, is studied from the standpoint of its decoupling fixed point map and the numerical approximate fixed point map. Variational principles will be discussed for this process and for discretizations achieved by use of generalized splines. By the choice of trial spa...

A system that builds a three-dimensional map of an indoor environment for a mobile robot is presented. The approach uses visual features extracted from stereo images as landmarks. A learning rule associated with each landmark is used to compute its existence state. New landmarks are merged into the map and transient landmarks are removed from the map over time. The location of the landmarks in ...

Speech recognition is a diicult problem due to the inability of current systems to cope with connected speech. Neural networks are able to learn some aspects of this task. An unsupervised learning scheme like the self-organising map can be used to both classify and order the speech sounds and provide a front end to higher level processing. A map of phonemes (phonotopic map) is used to trace tra...

The generation of novel Mycobacterium avium subsp. paratuberculosis (MAP)-specific monoclonal antibodies and phage-display derived peptide binders, along with their application for the magnetic separation (MS) of MAP cells, is described. Our aim was to achieve even greater MAP capture capability than is possible with peptide-mediated magnetic separation (PMS) using a 50:50 mix of biotinylated-a...

In this paper we present a method for simulating physical behaviour and rendering of water drops in real-time. Our algorithm is based on processing water information stored into a texture resembling a height map. Thus calculation on the Graphics Processing Unit is possible. Texels on the height map retrieve how much of their current water amount remains and how much water is provided from texel...
