Does it matter who contributes: a study on featured articles in the german wikipedia
TLDR
We explore on the German Wikipedia whether only the mere number of contributors makes the difference or whether the high quality of featured articles results from having experienced authors contributing with a reputation for high quality contributions. Expand

Communication Between Process and Structure: Modelling and Simulating Message Reference Networks with COM/TE
TLDR
Focusing on observable message signs and referencing structures, communication processes can be described and analysed as message reference networks which are characterized by dynamic pattern evolution. Expand

From Motion Observation to Qualitative Motion Representation
TLDR
We propose a generalization algorithm that abstracts from irrelevant details of a course of motion in order to represent the coarse structure qualitatively. Expand

Determination of hydroxy metabolites of cocaine from hair samples and comparison with street cocaine samples.
Drugs which are commonly smoked or sniffed (e.g. cocaine), can contaminate hair through smoke or dust; therefore testing for metabolites, especially hydroxy metabolites, is highly recommended. TheExpand

A Framework for Mobile Intention Recognition in Spatially Structured Environments
TLDR
We present a framework for mobile intention recognition that covers all levels, from low-level position data to high-level intentions, with the detailed structure of the motion track as an intermediate level. Expand

Qualitative Repräsentation und Generalisierung von Bewegungsverläufen
TLDR
Ein wesentlicher Schritt in der Verarbeitung von Bewegungsverlaufen ist deren Generalisierung (Vereinfachung und Glattung) in unterschiedlichen Referenzrahmen. Expand
