Selection of dune shapes and velocities . Part 1 : Dynamics of sand , wind and barchans .
Almost fifty years of investigations of barchan dunes morphology and dynamics is reviewed, with emphasis on the physical understanding of these objects. The characteristics measured on the field (shape, size, velocity) and the physical problems they rise are presented. Then, we review the dynamical mechanisms explaining the formation and the propagation of dunes. In particular a complete and or...
متن کاملDo small worlds synchronize fastest?
Small-world networks interpolate between fully regular and fully random topologies and simultaneously exhibit large local clustering as well as short average path length. Smallworld topology has therefore been suggested to support network synchronization. Here we study the asymptotic speed of synchronization of coupled oscillators in dependence on the degree of randomness of their interaction t...
متن کاملGeoregistration of Remotely Sensed Imagery
DEFINITION Georegistration is the alignment of an unreferenced image with a geodetically (latitude, longitude, and elevation based) calibrated reference image [1]. In general, this process aligns two images (satellite is the most common, but is not limited to satellite images) and correlating the images to a physical location by examining a set of distinguishable points. Figure 1 shows an examp...
متن کاملSelection of Remotely Sensed Data
An increasing number of sensors are available for forest ecologists and managers seeking to map attributes of forest canopy cover, forest structure and composition, and their dynamics. This Chapter seeks to put these advances within the context of the needs of forest managers and scientists. To do so, we review the basic physics behind a variety of imagery types, discuss fundamental limitations...
