Contextualising Archaeological Information Through Interactive Maps
Many web sites use maps delivered as non-interactive images. With the development of web-enabled mapping, new methods of presenting and contextualising archaeological and historical data are becoming available.

1/f Noise and Long Configuration Memory in Bak-Tang-Wiesenfeld Models on Narrow Stripes [PDF]
We report our findings of an 1/f power spectrum for the total amount of sand in directed and undirected Bak-Tang-Wiesenfeld models confined on narrow stripes and driven locally. The underlying mechanism for the 1/f noise in these systems is an exponentially long configuration memory giving rise to a very broad distribution of time scales.

Free tools for crystallographic symmetry handling and visualization
In crystallography there exist a wide variety of online resources such as web pages, interactive applets, databases and programs that can be implemented in both virtual and traditional classrooms. Among these, the Bilbao Crystallographic Server, the Cambridge Structural Database, Mercury, VESTA and Jmol are highlighted for teaching fundamental ...

Qualitative Theory for Lensed QSOs [PDF]
We show that some characteristics of multiply-imaged QSO systems are very model-independent and can be deduced accurately by simply scrutinizing the relative positions of images and galaxy-lens center. These include the time-ordering of the images, the orientation of the lens potential, and the rough morphology of any ring.

MyChemise: A 2D drawing program that uses morphing for visualisation purposes
MyChemise (My Chemical Structure Editor) is a new 2D structure editor. It is designed as a Java applet that enables the direct creation of structures in the Internet using a web browser. MyChemise saves files in a digital format (.cse) and the import and

A portable modeler of lensed quasars [PDF]
We introduce and implement two novel ideas for modeling lensed quasars. The first idea is to require different lenses to agree about H_0. This means that some models for one lens can be ruled out by data on a different lens. We explain using two worked examples.

Simulating a Rotational Inverted Pendulum Model by using Matlab and Easy Java Simulations
This paper presents the analysis, design and construction of a virtual simulator, in which the behavior of a non-lineal system as the rotational inverted pendulum is represented graphically in an interface.

Graphle: Interactive exploration of large, dense graphs
Background A wide variety of biological data can be modeled as network structures, including experimental results (e.g. protein-protein interactions), computational predictions (e.g. functional interaction networks), or curated structures (e.g.
