The aim of this study is to generate a quality-controlled sub-kilometer dataset of the fraction of absorbed photosynthetically active radiation (FAPAR) across Scandinavia from satellite. FAPAR is required for estimating the amount of PAR absorbed (APAR) by vegetation, which in turn allows for estimation of carbon uptake. In this study, FA-PAR was modeled from normalized difference vegetation index

A previous investigation has shown that at normal angle of incidence, the integral of the reflectance over wavelength is bounded for a flat metal backed absorber. The bound is applicable to any absorber made of linear, time-invariant, causal and passive materials. We generalize the physical bound to arbitrary angle of incidence and polarization. Different design examples and numerical calculations

In Networked Control Systems, time-varying delays and loss of data are two important problems to be taken into account. In this paper, in order to face them, the design of a predictor-observer for possible unstable systems is proposed. A delay-dependent time varying stability condition is expressed in terms of LMIs. Stability and robustness is proved.

Based on an ethnographic study among selected ethnic minority groups in Kon Tum province of the Central Highlands of Vietnam, this paper discusses how popular discourses about social-cultural differences between the ‘civilized’ lowland majority Kinh people and ‘backward’ upland minority groups impact on political participation of the local people. Popular assumptions contend that ethnic minorities

Popular Abstract in Swedish Hantering av risker i företag och organisationer har haft en lång och komplicerad historia. På åttiotalet, och i början av nittiotalet, var uppfattningen att om en olycka inträffade i en organisation, som påstods vara nära nog perfekt, måste det bero på ”den mänskliga faktorn”, dvs. att en eller flera medarbetare inte gjorde som de borde ha gjort. Orsakerna till olyckaIntroduction Risk management in enterprises, organisations and companies has had a long and complicated history. During the eighties, and at least during the beginning of the nineties, the notion concerning risk management was that if an accident happened in an otherwise perfect system it was due to the human operator in some way being the cause of the error. The cause for the accidents was desc

The erection of roadside memorials in Sweden is commonly considered a novel practice, appearing during the last 10-15 years. Nevertheless similar precedent practices can be found in the history of Sweden. Stories about marking the site of an unexpected death with a cross could be said to date back to the eleventh century legend of Saint Sigfrid, telling of the first English missionary to spread C

Whether action is joint and conforms to agents´ commitments, and what capacities agents must exercise in order to engage in joint action, is a matter of the social structure of the situation of interaction, not of the agents´ believed sharing of mental states.
