The surface of the Earth is snow-covered at least seasonally over large areas. This snow highly dynamic, particularly under influence strong winds. motion particles driven by wind not only changes cover but has important consequences for atmosphere in that it adds mass and moisture extracts heat. Large scale meteorological climatological models neglect these dynamics or produce conflicting resu...

Maintaining standing vegetative soil cover is an important method of wind erosion control. However^ an improved physical understanding of the mechanisms by which standing vegetation control wind erosion is needed so the erosion control level of vegetation not previously tested in a wind tunnel can be calculated. In this report, a theoretical approach that accounts for both the surface friction ...

Funneling and saltation are two major illusory tactile feedback techniques. Recently, these techniques have been found to be applicable to eliciting “out of the body” experiences as well (e.g. through user-held external objects). We discuss the possibility of applying this phenomenon to build a less cumbersome feedback device with a reduced number of vibrators, and interact with virtual and aug...

Aeolian transport is an important mechanism for the transport of sand on Earth and on Mars. Dust and sand storms are common occurrences on Mars and windblown sand is responsible for many of the observed surface features, such as dune fields. A better understanding of Aeolian transport could also lead to improvements in pneumatic conveying of materials to be mined for life support on the surface...
