On the Successive Overrelaxation Method

Problem statement: A new variant of the Successive Overrelaxation (SOR) method for solving linear algebraic systems, the KSOR method was introduced. The treatment depends on the assumption that the current component can be used simultaneously in the evaluation in addition to the use the most recent calculated components as in the SOR method. Approach: Using the hidden explicit characterization ...

Situated Views on Augmented Memories

Long-term records of user actions captured and recorded in an intelligent environment allow for realizing new kinds of user support, which exploit a user’s past experiences for supporting his or her future actions. In this article, a mobile shopping assistant equipped with such augmented memories serves as background for a discussion of a user interface especially tailored to support typical fu...

Successive Rank-Revealing Cholesky Factorizations on GPUs

We present an algorithm and its GPU implementation for fast generation of rank-revealing Cholesky factors {Rk} at output in response to a sequence of data matrices {Ak} at input. The Cholesky factors are subsequently used for calculating adaptive weight vectors as control feedback in space-time adaptive processing (STAP) and sensing systems [3]. The size of the input data matrices is m× n, wher...
