Hanne Bruun: Daytime talkshows i Danmark

Hanne Lehn

Uffe Haagerup , Hanne Schultz and Steen Thorbjørnsen

In 1982 Pimsner and Voiculescu computed the K0and K1-groups of the reduced group C∗-algebra C∗ red(Fk) of the free group Fk on k generators and settled thereby a long standing conjecture: C∗ red(Fk) has no projections except for the trivial projections 0 and 1. Later simpler proofs of this conjecture were found by methods from K-theory or from non-commutative differential geometry. In this pape...

Snoring (I). Daytime sleepiness in regular heavy snorers.

Fifteen men, mean (means) age 44 years, were investigated. Their means body mass index was 21.9 kg/m2, and all of them had a respiratory disturbance index below 5 and had good nocturnal oxygen saturation. The subjects were monitored several nights both with and without the following devices: a tight-fitting facial mask, a pneumotachometer, and an esophageal balloon. They were also monitored wit...

New FFT structures based on the Bruun algorithm

In some signal processing applications, the input data are real. In this case, the Bruun algorithm for computation of the Discrete Fourier Transform (DFT) is attractive. This correspondence offers a pipeline and a recirculated shuffle network implementation of the Bruun algorithm. The parallel pipeline and recirculated FFT structures are implemented based on the modified perfect shuffle network.

Uncertainties in Sandy Shorelines Evolution under the Bruun Rule Assumption

In the current practice of sandy shoreline change assessments, the local sedimentary budget is evaluated using the sediment balance equation, that is, by summing the contributions of longshore and cross-shore processes. The contribution of future sea-level rise induced by climate change is usually obtained using the Bruun rule, which assumes that the shoreline retreat is equal to the change of ...
