The inversion of physics based models presents an alternative to empirical relationships for the retrieval of forest structure from Synthetic Aperture Radar (SAR) data. A major disadvantage of such techniques is instability in the presence of moderate levels of noise. The effects of noise on the accuracy with which parameters can be retrieved is evaluated in this study under a number of conditions.

Bolender, Douglas J. This chapter argues that the eventful paradigm is of limited use to the archaeological researcher and contends that it is little more than a modern reinterpretation of determinism. The chapter uses volcanic eruptions on a number of scales to illustrate the dangers of adopting an eventful research paradigm and argues instead for a more nuanced approach based on research hypotheses that acknowledge how little we actually know of the past, human response, and its context. chapter: 11 Wed, 01 Sep 2010 00:00:00 GMT http://hdl.handle.net/2160/12804 2010-09-01T00:00:00Z
