In the Natscan project terrestrial laser scanning is used for deriving detailed information about tree quality and forest stand parameters. The authors describe an automatic method for determining tree positions and diameters at breast height (DBH) using terrestrial laser scanner data. Special attention is given to the data-processing that must be carried(More)
We present a 2D-and 3D-lattice Boltzmann model for the treatment of free surface flows including gas diffusion. Interface advection and related boundary conditions are based on the idea of the lattice Boltzmann equation. The fluid dynamic boundary conditions are approximated by using the mass and momentum fluxes across the interface, which do not require(More)
Based on experiences from the NATSCAN-project this contribution focuses on the evaluation of two hypotheses: (i) Terrestrial laser scanning and corresponding data analysis is ready to be used in standardized forest inventory sampling. (ii) Data quality as well as characteristics related to the technique of laser scanning widen the data base for forest(More)
A framing effect occurs when different, but logically equivalent, words or phrases (e.g., 10% employment or 90% unemployment) cause individuals to alter their decisions. Demonstrations of framing effects challenge a fundamental tenet of rational choice theory and suggest that public opinion is so malleable that it cannot serve as a useful guide to(More)
We expand Denzau and Munger's 1986 model of " How Unorganized Interests Get Represented " to address cross-national differences in electoral systems. We look at how individual legislators allocate their efforts to serving unorganized constituents versus organized groups. Our model shows how the optimal allocation of effort is affected by differences in(More)
Timbre distance and similarity are expressions of the phenomenon that some music appears similar while other songs sound very different to us. The notion of genre is often used to categorize music, but songs from a single genre do not necessarily sound similar and vice versa. In this work, we analyze and compare a large amount of different audio features(More)
In this paper, we present an efficient exploration algorithm for architecture/compiler co-designs of application-specific instruction-set processors. The huge design space is spanned by processor architecture parameters as well as different compiler optimization strategies. The objective space is multi-dimensional including conflicting objectives such as(More)

In the present study lectin-binding sites were investigated for the lectins Ricinus communis agglutinin (RCA I), wheat germ agglutinin (WGA), soya bean agglutinin (SBA), concanavalin A (Con A), Lotus tetragonolobus(LTA) and Limulus polyphemus agglutinin (LPA) during the initial stages of vasculogenesis of the CNS-anlage in 10 to 12-day-old NMRI mouse(More)
Timbre distances and similarities are an expression of the phenomenon that some music appears similar while other songs sound very different to us. The notion of genre is often used to categorize music, but songs from a single genre do not necessarily sound similar and vice versa. Instead we aim at a visualization of timbre similarities of sound within a(More)
