Jingle Bells: Solving the Santa Claus Problem in Polyphonic C

The Santa Claus problem is an interesting exercise in concurrent programming which has been used in a comparison of the concurrency mechanisms of Ada and Java. We present a simple solution to the problem in Polyphonic C , an extension of C with new concurrency constructs based on the Join calculus.

Comparing SOM neural network with Fuzzy c

In this paper we present a comparison among some nonhierarchical and hierarchical clustering algorithms including SOM (Self-Organization Map) neural network and Fuzzy c-means methods. Data were simulated considering correlated and uncorrelated variables, nonoverlapping and overlapping clusters with and without outliers. A total of 2530 data sets were simulated. The results showed that Fuzzy c-m...

Bjørn Jespersen Predication and Extensionalization

In his 2000 book Logical Properties Colin McGinn argues that predicates denote properties rather than sets or individuals. I support the thesis, but show that it is vulnerable to a type-incongruity objection, if properties are (modelled as) functions, unless a device for extensionalizing properties is added. Alternatively, properties may be construed as primitive intensional entities, as in Geo...

Partial Dynamical Systems and Af C * -algebras

We obtain a characterization in terms of dynamical systems of those r-discrete groupoids for which the groupoid C∗algebra is approximately finite-dimensional (AF). These ideas are then used to compute the K-theory for AF algebras by utilizing the actions of these partial homeomorphisms, and these K-theoretic calculations are applied to some specific examples of AF algebras. Finally, we show tha...
