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)
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)
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)
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)
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)
In the design of application-specific instruction set processors (ASIPs) a tight interplay between architecture and compiler is of utmost importance. Here, we try to characterize the design space of both compiler frontend (intermediate code optimization) and backend (architecture-specific code generation) that is used in order to do <i>Architecture/Compiler(More)
The management and planning of forests presumes the availability of up-to-date information on their current state. The relevant parameters like tree species, diameter of the bowl in defined heights, tree heights and positions are usually represented by a forest inventory. In order to allow the collection of these inventory parameters, an approach aiming on(More)
