3d Virtual Reconstruction and Visualization of Complex Architectures – the “3d-arch” Project

The 3D Virtual Reconstruction and Visualization of Complex Architectures (3D-Arch) project started in 2005 and is now completed. It proposes an integrated approach based upon a combination of different 3D measurement techniques for the virtual reconstruction of complex architectures like those found in medieval castles. This paper summarizes the work done in this project, consolidates increment...

Knowledge Discovery using clustering techniques

The main goal of this paper is to provide results and findings of some preliminary tests with two dif ferent clustering techniques suitable for knowledge discov ery in databases (KDD). We used Bayesian unsupervised classification (based on the AutoClass ystem) and the SelfOrganizing Map ( SOM) as a prominent unsupervised neural network to analyze a real-world atabase of ticket sales for castles...

“Links to the Present”: The Long History of Contested Heritage in Ghana’s Slave Castles

The rise in African American heritage tourism to the castles has produced an abundance of scholarly books and articles. These works often try to place African American tourism to Ghana in the context of global heritage tourism or the Black Atlantic. Most of these works are anthropological, covering the sometimes volatile encounter between African Americans and Ghanaians at the castles. These et...

We describe a series of new applications of gravitational lenses as astrophysical and cosmological tools. Such applications are becoming possible thanks to advances in the quality and quantity of observations. CASTLES (CfA-Arizona-Space-Telescope-LEns-Survey) 1 is an ongoing project that exploits the sensitivity and resolution of the Hubble Space Telescope (HST) at optical and infrared waveleng...
