Biophysical drought metrics extraction by time series analysis of SPOT Vegetation data

The repeated occurrence of severe wildfires has highlighted the need for development of effective vegetation moisture monitoring tools. The normalized difference infrared index (NDII) derived from SPOT Vegetation satellite data and the Keetch-Byram drought index derived from temperature and rainfall data are both related to vegetation moisture dynamics. Autocorrelation of time series is a major is

Cooperation and conflict over the struggle to reproduce in harsh environments : An experimental field study on ostriches

Man brukar höra att evolution handlar om att de starkaste, de bäst lämpade, överlever. Detta för tankarna till en värld full med översittare, som hänsynslöst driver fram och lämnar de svaga bakom sig. Men det behöver inte vara så. Denna avhandling visar oss att gemenskap är styrka, och att evolutionen skapar liv där de svaga ibland sitter på de starkas axlar.Strutsar är märkliga varelser. De ser uPeople are used to hearing that evolution is about the survival of the fittest. Theyimagine a world full of bullies that ruthlessly fight their way to the top in the struggle for life, leaving the weak behind. But this doesn’t need be the case. This thesis reveals a different side of evolution, where survival means working together, and where the weak can ride on the shoulders of the fit.Ostriches

Threshold Computation for Spatially Coupled Turbo-Like Codes on the AWGN Channel

In this paper, we perform a belief propagation (BP) decoding threshold analysis of spatially coupled (SC) turbo-like codes (TCs) (SC-TCs) on the additive white Gaussian noise (AWGN) channel. We review Monte-Carlo density evolution (MC-DE) and efficient prediction methods, which determine the BP thresholds of SC-TCs over the AWGN channel. We demonstrate that instead of performing time-consuming MC-

Bit : An examination of the explanatory power of a meaning potential approach to the description of lexical meaning

Through a detailed examination of the use of the lexical item bit in four English language corpora, this study assesses whether the assumptions guiding a meaning potential perspective on lexical meaning (e.g. Allwood 1999, 2003; Croft and Cruse 2004, Paradis 2005; Fauconnier 2007) are reconcilable with a practicable description and explanation of attested language use. To this end, the study emplo
