The Complexity of Polynomials and Their Coefficient Functions
We study the link between the complexity of a polynomial and that of its coefficient functions. Valiant’s theory is a good setting for this, and we start by generalizing one of V...

Knowledge-Based Event Detection in Complex Time Series Data
This paper describes an approach to the detection of events in complex, multi-channel, high frequency data. The example used is that of detecting the re-siting of a transcutaneous ...

Composing Complex Behavior from Simple Visual Descriptions
An often-mentioned advantage of rule-based programming languages is that a program can be extended simply by adding a few more rules. In practice however, the rules tend to be dep...

I/O Complexity for Range Queries on Region Data Stored Using an R-tree
In this paper we study the node distribution of an Rtree storing region data, like for instance islands, lakes or human-inhabited areas. We will show that real region datasets are...
