[1] SPECTRA (Surface Processes and Ecosystem Changes Through Response Analysis) is one of the core candidate missions which is being proposed for implementation in the European Space Agency (ESA) Earth Explorer program of research oriented missions. The scientific objective of the SPECTRA mission is to describe, understand, and model the role of terrestrial vegetation in the global carbon cycle...

Processing of land surface temperature from long time series of AVHRR (Advanced Very High Resolution Radiometer) requires stable algorithms, which are well characterized in terms of accuracy, precision and sensitivity. This assessment presents a comparison of four mono-window (Price 1983, Qin et al., 2001, Jiménez-Muñoz and Sobrino 2003, linear approach) and six split-window algorithms (Price 1...

ISBN 91-554-6351-7 Scientific applications require processing of high-volume on-line streams of numerical data from instruments and simulations. In order to extract information and detect interesting patterns in thes...

A Markov chain model for evaluating the performance of a multistage ATM switching fabric using split shared buuered switch elements (SE) is proposed. By comparing the results obtained from the proposed model and simulations, it is shown that the model is accurate in the presence of uniform and non-uniform traac in the switch. To eliminate the innuence of head of line blocking, a non-FIFO queuei...
