Random Field Models for Graph LayoutUlrik Brandes

We propose a new framework for the layout of graphs, which both uniies and generalizes many approaches known from the literature. Doing so, we brieey survey a number of models, particularly including force directed placement approaches. Our model is based on the stochastic concept of random elds, which have applications in various other areas such as physics, biology, economics, or medical imag...

Editorial Atypical Speech Georg

One of the most important aspects of spoken language is its large degree of variability. Variability in speech is caused by many different sources, for instance, changes of the acoustic environment or transmission channel and differences between speakers or various speaking styles. Successful speech processing systems typically combine several different means to cope with the unwanted variabili...

Georg Friedrich Händel's strokes.

Georg Friedrich Händel was a musical giant and probably the first composer to be the manager and promoter of his own works. The story of his life and illnesses is full of myths, invented and embellished by various biographies. Existing pathographies written by authors from various specialities suggested he suffered from psychiatric diseases like cyclothymia or mania and rheumatologic disorders ...

Towards Improving Brandes' Algorithm for Betweenness Centrality

Betweenness centrality, measuring how many shortest paths pass through a vertex, is one of the most important network analysis concepts for assessing the (relative) importance of a vertex. The famous state-of-art algorithm of Brandes [2001] computes the betweenness centrality of all vertices in O(mn) worst-case time on an n-vertex and m-edge graph. In practical follow-up work, significant empir...
