Simulating CSF flow dynamics in the normal and chiari I subarachnoid space during rest and exertion
(2013)
BACKGROUND AND PURPOSE: CSF fluid dynamics in healthy subjects and patients with Chiari I have been characterized during rest with phase-contrast MR imaging and CFD. CSF flow velocities and pressures in the nonresting state ...
'Bomb-making for beginners': Inside an al-Qaida e-learning course
(2013)
This study explores how terrorists utilize the Internet to learn bomb-making skills. Unlike previous studies, it does not focus on assessing the quality of online bomb recipes. Rather, it discusses the efforts being made ...
Brukerveiledning for Concept-databasen
(2010)
Denne rapporten er en teknisk og praktisk brukerveiledning for Concept-databasen utviklet ved
FFI i tilknytning til oppdrag 3380 – Offentlige anskaffelser, kontraheringsformer og
kontraktsmodeller (Concept-programmet). ...
Naval sonar disrupts foraging in humpback whales
(2016)
Modern long-range naval sonars are a potential disturbance for marine mammals and can cause disruption of feeding in cetaceans. We examined the lunge-feeding behaviour of humpback whales Megaptera novaeangliae before, ...
Convex Variational Methods on Graphs for Multiclass Segmentation of High-Dimensional Data and Point Clouds
(2017)
Graph-based variational methods have recently shown to be highly competitive for various classification problems of high-dimensional data, but are inherently difficult to handle from an optimization perspective. This ...
Turbulence characterization and image processing data sets from a NATO RTO SET 165 trial in Dayton, Ohio, USA
(2012)
The performance of optical systems is degraded by atmospheric turbulence. Over propagation distances that exceed several kilometers, it is difficult to evaluate its impact because of terrain variability - a factor that ...
Underwater Acoustic Network Simulation With Lookup Tables From Physical-Layer Replay
(2015)
An underwater acoustic network simulation methodology is presented that is based on lookup tables (LUTs) with physical-layer error ratios. These LUTs are prepared with a validated replay channel simulator, which is here ...
The use of synthetic aperture sonar to survey seafloor massive sulfide deposits
(2015)
With the advent of advanced deep sea mining technology, seafloor mining is poised to begin on a
global scale. For the success of any mining operation, it is crucial that both the operators and
regulatory bodies possess ...
A logical characterisation of SPARQL federation
(2014)
The paper provides a logical characterisation of distributed processing of SPARQL queries. The principal notion analysed is that of a distribution scheme; a pair consisting of an evaluation rule and a distribution function. ...
Large-eddy simulation of dense gas dispersion over a simplified urban area
(2017)
Dispersion of neutral and dense gas over a simplified urban area, comprising four cubes, has been investigated by the means of large-eddy simulations (LES). The results have been compared to wind tunnel experiments and ...
