Fluid mechanics to improve fuel consumption

Cars today must be certified for fuel consumption and emissions. Petter Ekman shows in his doctoral thesis how car manufacturers can make considerable resource savings for estimations of aerodynamics effects even from small geometrical details.

Paradigm shift to give superfast supercomputers

“In just a few years we’ll have supercomputers that work at exaflop speeds. We are witnessing a paradigm shift.” The words are those of Thomas Sterling, a grand old man in supercomputing and professor at Indiana University, visiting NSC and LiU.

New research supercomputer online

Swedish research has now gained access to the first 600 nodes of the new supercomputer Tetralith, which will be the most powerful computer in the Nordic region when it comes fully online this autumn. Researchers at LiU also have access to Sigma.

Blood flow in the heart revealed in a flash

Researchers at LiU have for the first time been able to use information from computer tomography images to simulate the heart function of an individual patient. Some of the modelling methods they use have been developed in the motor industry.

NSC at LiU to install Scandinavia’s most powerful supercomputer

Swedish researchers will gain access to significantly higher computing power when the most powerful computer in the Nordic region, Tetralith, is installed at National Supercomputer centre. The maximum speed is estimated to be just over 4 petaflops.

China - A superpower in supercomputers

Milky Way-2 takes second place in the Top500 list of supercomputers. This machine is located in Guangzhou and will reach a performance of 100 petaflops. LiU just happens to be in the process of procuring Sweden's most powerful supercomputer.

Large research grant for greener timber trucks

With the aid of a supercomputer, a wind tunnel and a research grant of SEK 5.7 million, the 2,000 timber trucks in Sweden are to achieve lower fuel consumption, becoming in this way a little bit greener.

A transport vehicle of the future

Emissions from the transport sector can be drastically reduced with more streamlined trucks. Researchers have calculated, and road carrier owner Erik Alfredsson has built an initial version of the transport vehicle of the future.

Heart valves in a new light

In all probability, at least one of the heart’s valves – the mitral valve – functions entirely differently than previously believed. Neil Ingels, professor at Stanford School of Medicine is now putting out all the scientific data on the Internet.
