Påliteligheten av selvrapportert alkoholkonsum. Svalbardstudien 1988-89

The annual variation in activity and funding for acute public hospitals in NSW, 1988-89 to 1992-93.

Casemix-based funding was introduced into the Victorian health system without an assessment of the annual variation in inpatient activity. Before undertaking such a funding reform, it would be appropriate to determine the level of annual variation in inpatient activity for individual hospitals that could be attributable to chance or random variation. If the annual random variation is not accoun...

[Comparison between ski and snowboarding accidents. Current overview from the ski area Arosa (Switzerland) (1988/89 to 1994/95)].

The ski resort of Arosa (Switzerland) is geographically isolated and has recorded it winter sports accidents since 1969. Based on this reliable data, the ski (3877 in total) and snowboard (512 in total) accidents of the last seven years were statistically analyzed. The study showed that snowboarding isn't much more dangerous than skiing the number of accidents was about the same in both groups,...

Occasional Paper No. 89-1: Employment of Black and Hispanic Police Officers, 1983-1988: A Follow-up Study

Utvikling av altruisme med gjenkjennelse av slektskap i evolusjonære roboter

Swarm robotics provides ways of solving problems using groups of autonomous robots that display emergent intelligent behaviour. Control mechanisms for these robots can be designed by using mechanisms from evolutionary robotics. In order to ensure that the controllers are adaptive and capable of learning new behaviour controllers are artificially evolved using techniques inspired by natural evol...

The permutation classes Av(1234, 2341) and Av(1243, 2314)

We investigate the structure of the two permutation classes defined by the sets of forbidden patterns {1234, 2341} and {1243, 2314}. By considering how the Hasse graphs of permutations in these classes can be built from a sequence of rooted source graphs, we determine their algebraic generating functions. Our approach is similar to that of “adding a slice”, used previously to enumerate various ...
