Simultaneous channel and symbol maximum likelihood estimation in Laplacian noise

This paper treats channel estimation and signal detection in Laplacian noise. The received signal is assumed to be a transmitted signal which has been corrupted by an unknown channel, modeled as a FIR filter, the output being further disturbed by additive independent Laplacian noise. The transmitted signal is assumed to depend on an unknown parameter belonging to a known finite set. The simultaneo

The threat from non indigenous species - ecosystem vulnerability, global distribution and co-occurrence with other major threats

Popular Abstract in Swedish Främmande arter är sådana som introducerats med människans hjälp till områden de inte kan sprida sig till på egen hand. Om en introducerad art är framgångsrik och lyckas etablera och sprida sig i mottagarregionen kan den påverka de inhemska arterna genom predation, konkurrens, hybridisering, parasitism och förändring av habitat. Eftersom arterna i mottagarområdet inte hWe live in a globalised world where people and goods travel large distances. Various species are brought along on these journeys, intentionally or as hitchhikers. Some of these species establish populations in regions to which they could not have spread without human assistance, and where they are considered to be non indigenous species (NIS). These species can affect the ecosystem in the recipien

Two Sides of the Same Coin? A Preliminary Analysis of Sustainable Development Opportunities Identified in National Communications of Non-Annex I Parties

The aim of this paper is to study the extent to which non-Annex I countries are implementing or exploring select actions that support both climate change mitigation and sustainable development objectives in the energy sector. The research is based on a survey of the national communications of 100 non-Annex I Parties to the UNFCCC. Although national communications are intended to provide informatio
