The nanoscale and hydrophobic structures of the network enable the otherwise water-absorbing cotton to repel water nearly as efficiently as the lotus leaf. Furthermore, the treated fabrics are stronger and more resistant to tears. Nanotube concentrations of over 2% in the applied emulsion...

This paper discusses the development of a virtual reality museum. An effort was made so that the virtual museum represents the Byzantine, medieval museum in Rhodes as closely as possible. Simple and low cost tools were used to allow rapid development of relatively good quality applications. This was attempted to validate our belief that the construction of VR applications is within the abilitie...

In addition to observing astronomical objects through the electromagnetic radiation they give off, astronomers also study the universe by analyzing gravitational effects on mater. More specifically, one can work back from these observed effects to determine the mass distribution in the universe (both inside and outside galaxies). In this project, we worked on one specific gravitational effect: ...
