Aspekter af ordbøgers samfundsmæssige betydning

In this paper the assumption is put forward that a precondition fora dictionary to obtaina position of importance in a speak.ing community is that the users regard the dictionaryas an authority. Furthermore it is assumed that five aspects of comprehensivemonolingual dictionaries are of specific interest to the public. The aspects are: thedictionary as: 1. a description of language usage, 2. a topic of discussion, 3. aknowledge base, 4. a period picture and 5. a learning device. In an attemptto define the factors which are necessary for the dictionary to become an authoritywith respect to the aspects, each aspect is related to the authority demand

The Effect of Thermal Neutrino Motion on the Non-linear Cosmological Matter Power Spectrum

We have performed detailed studies of non-linear structure formation in cosmological models with light neutrinos. For the first time the effect of neutrino thermal velocities has been included in a consistent way, and the effect on the matter power spectrum is found to be significant. The effect is large enough to be measured in future, high precision surveys. Additionally, we provide a simple but accurate analytic expression for the suppression of fluctuation power due to massive neutrinos. Finally, we describe a simple and fast method for including the effect of massive neutrinos in large-scale N-body simulations which is accurate at the 1% level for \sum m_nu < 0.15 eV.Comment: 17 pages, 7 figures.
