A two-dimensional, zoomable, space filling user interface is presented for browsing conventional, hierarchical file systems. Through user studies the Goldleaf browser was compared with the widely used Microsoft Windows Explorer user interface. The times and number of mouse clicks to locate directories and files were recorded. The user studies found that the Goldleaf browser required less than h...

The mSpace Classical Music Explorer, available at http://demo.mspace.fm, is a Web-based explorer designed to improve access to the classical music domain, especially for those who do not have domain knowledge. We could characterize the approach as designed to support those who might say “I don’t know much about classical music, but I know what I like when I hear it.” For this group, browsing a ...

The Narrative Explorer is an interactive web application for text visualization and analysis. The texts are visualized in the Narrative Explorer in two ways.

This paper describes work in the e-Science Core Programme project, gViz, to develop visualization middleware. The focus in this paper is the evolution of our work to Grid-enable IRIS Explorer, a widely used dataflow visualization system from NAG. A crucial feature of IRIS Explorer is the ability to include user-written simulation code as part of the dataflow pipeline, offering the opportunity o...

the effect of steel plate thickness on the repair effectiveness of rc beam is presented in this paper. a total of four beams were tested, one beam repaired by cfrp with a thickness of 1.2 mm and used as a control beam, and three beams repaired by a steel plate. steel plates with a thickness of 2 mm, 3 mm, and 4 mm were used in repairing the beams. the maximum load-carrying capacity, deflection ...
