The dramatic increase of data breaches in modern computing platforms has emphasized that access control is not sufficient to protect sensitive user data. Even in the case of honest parties, unknown so...
Ice flow velocity over long time series in East Antarctica plays a vital role in estimating and predicting the mass balance of Antarctic Ice Sheet and its contribution to global sea level rise. Howeve...
The South Atlantic is one of the youngest of all the major oceans. It has prominent topographic features, in particular, the Mid-Atlantic Ridge. This feature largely determines deepwater circulation p...
Vegetation mapping of national park units in the southeastern United States is being undertaken by the Center for Remote Sensing and Mapping Science at the University of Georgia. Because of the uniqu...
