Mapping the forest cover of Uganda with Spot (XS) and Landsat (ETM+) images : (a case study of Bwindi Impenetrable National Park, Uganda)
It is well established that land cover information is an essential component in the creation of spatial information systems. Lack of current land cover information constitutes a weakness in land resource management especially in developing countries like Uganda. In response to this need, the thesis …

Surface reflectance characteristics of Langjökull, Iceland
ATM, ETM+ and MODIS radiance data collected for the surface of Langjokull during August 2007. Radiance data from the three different instruments was then converted to surface broadband albedo using a number of different methods. The differences between the methods used to derive the surface albedo …

Atomistic simulations of driven alloys: a study of effective temperature models for low and high temperature applications
… alloys has been the effective temperature model (ETM) which posits that the non-equilibrium phases formed during processing will correspond to the equilibrium phase at a different, typically higher, effective temperature different from the ambient one. The underlying intuition behind this model is …
