چکیده
Introduction Landsat Thematic Mapper ( TM ) imagery was used to analyze patterns of landscape diversity in the seasonal tropical forests of northeastern Guatemala. TM radiance and the radiance coefficient of variation (CV) were significant in discriminating land-cover types. Cluster analysis of TM4, TM5, and TM7 radiance produced six distinct types of landcover. Green leaf biomass from TM4 and canopy closure and degree of senescence from TM5 and TM7 represent the most important variables in discriminating between landcover types in the uplands and the lowland swamps respectively. Patterns of landscape diversity reflected in three landscape indices were also examined: the number of landcover types (LCT), the Shannon-Weaver index of landscape evenness (S-W), and a topographic index (TI).

متن کاملDisconnected Loops with Twisted Mass Lattice QCD
We give a general introduction and discussion of the issues involved in using the twisted mass formulation of lattice fermions in the context of disconnected loop calculations, including a short orientation on the present experimental situation for nucleon strange quark form factors. A prototype calculation of the disconnected part of the nucleon scalar form factor is described. c Copyright own...
متن کاملNeutrino Telescope Modelling of Lorentz Invariance Violation in Oscillations of Atmospheric Neutrinos
One possible feature of quantum gravity may be the violation of Lorentz invariance. In this paper we consider one particular manifestation of the violation of Lorentz invariance, namely modified dispersion relations for massive neutrinos. We show how such modified dispersion relations may affect atmospheric neutrino oscillations. We then consider how neutrino telescopes, such as ANTARES, may be...

متن کاملProbing Quantum Decoherence in Atmospheric Neutrino Oscillations with a Neutrino Telescope
Quantum decoherence, the evolution of pure states into mixed states, may be a feature of quantum gravity. In this paper, we show how these effects can be modelled for atmospheric neutrinos and illustrate how the standard oscillation picture is modified. We examine how neutrino telescopes, such as ANTARES, are able to place upper bounds on these quantum decoherence effects.
