Obscurance-based Volume Rendering Framework
(The Eurographics Association, 2008)
lighting effects in a faster way than global illumination. Its application in volume visualization is of special interest since it permits us to generate a high quality rendering at a low cost. In this paper, we propose ...
A New Generating Set Search Algorithm for Partially Separable Functions
A new derivative-free optimization method for unconstrained optimization of partially separable functions is presented. Using average curvature information computed from sampled function values the method generates an ...

Data Profiling to Reveal Meaningful Structures for Standardization
(The University of Bergen, 2009-11-20)
Today many organisations and enterprises are using data from several sources either for strategic decision making or other business goals such as data integration. Data quality problems are always a hindrance to effective ...
Implementation of Broadcast Domination Algorithms for Interval Graphs, Series-Parallel Graphs, and Trees
(The University of Bergen, 2004)
The State of the Art in Topology-based Visualization of Unsteady Flow
(Blackwell Publishing Ltd., 2011)
Vector fields are a common concept for the representation of many different kinds of flow phenomena in science and engineering. Methods based on vector field topology are known for their convenience for visualizing and ...
Curve Density Estimates
(Blackwell Publishing Ltd., 2011-06-28)
In this work, we present a technique based on kernel density estimation for rendering smooth curves. With this approach, we produce uncluttered and expressive pictures, revealing frequency information about one, or, ...
Improving Parallel Sparse Matrix-vector Multiplication
(The University of Bergen, 2013-12-19)
Sparse Matrix-vector Multiplication (SMvM) is a mathematical technique encountered in many programs and computations and is often heavily used. Solving SMvM in parallel allows for bigger instances to be solved, and problems ...
So you've got IPv6 address space. Can you defend it?
(The University of Bergen, 2014-05-29)
Internet Protocol version 6 (IPv6) is the successor of Internet Protocol version 4 (IPv4). IPv6 will become the next standard networking protocol on the Internet. It brings with it a great increase in address space, changes ...
Recursive Time-Frequency Reassignment
(The University of Bergen, 2008-11-18)
A fast algorithm for producing time-frequency representations (TFRs) is proposed. The resulting TFRs have optional time-frequency resolution up to optimality. The algorithm is further extended with a method known as ...
