Vehicular Ad-hoc Network Simulations with JANE

submitted by: sebastian

In this video we use the JANE simulator to present the relation between the performance of the IEEE 802.11b standard and the number of hops involved in the transmission of files when using car-to-car communications in Vehicular Ad-hoc Networks (VANETs). For more info, please visit: CARLINK

ATV: a very special delivery

submitted by: cristina
Early in 2008, an Ariane 5 rocket blasted off from Europe’s spaceport in French Guiana. The rocked carried the most sophisticated lorry ever built – the European Space Agency’s Automated Transfer Vehicle, the ATV.

The video - addressed mostly to the youngsters- tells the story of a very...

Ice Drillers are Hard Core

submitted by: ppza
Deciphering the secrets of past climate hidden in ice cores depends on the technical skills and ingenuity under pressure of drillers from ICDS, the University of Wisconsin-Madison's Ice Coring and Drilling Services. In this video, ICDS staffers Lou, Mike and Jay explain why they enjoy the life of drillers, braving extreme cold in some of the remotest regions of the globe. Mike says drilling requires both science and art, and why he keeps his hand on the cable even when it's minus 20; Lou...
