A survey of the polar cap density based on Cluster EFW probe measurements: Solar wind and solar irradiation dependence
(2012)
The plasma density above the Earth's polar caps provide crucial information about the state of the magnetosphere. This region of space is known for its tenuous plasma and extremely low plasma densities, thus making traditional ...
Fracture networks in sea ice
(2014)
Fracturing and refreezing of sea ice in the Kara sea are investigated using complex network analysis. By going to the dual network, where the fractures are nodes and their intersections links, we gain access to topological ...
Using the Power Balance Model to Simulate Cross-Country Skiing on Varying Terrain
(2014)
The current study adapts the power balance model to simulate cross-country skiing on varying terrain. We assumed that the skier’s locomotive power at a self-chosen pace is a function of speed, which is impacted by friction, ...
Obtaining spectral information from infrared scenarios using hyper-spectral cameras and cameras with spinning filter wheel
(2014)
In the past decades the Norwegian Defence Research Establishment (FFI) has recorded and characterized infrared scenarios for several application purposes, such as infrared target and background modeling and simulation, ...
Myndighetsutøver, ressursforvalter og livredder – den russiske kystvakten i støpeskjeen
(2016)
The Russian Coast Guard, or Beregovaya okhrana, was formally established in 2007 and plays a crucial role in the management of natural resources located in the vast maritime areas under Russian jurisdiction. The purpose ...
Sensor noise informed representation of hyperspectral data, with benefits for image storage and processing
(2011)
Many types of hyperspectral image processing can benefit from knowledge of noise levels in the data, which can be derived from sensor physics. Surprisingly, such information is rarely provided or exploited. Usually, the ...
A Study of the Detonation Properties, Propellant Impulses, Impact Sensitivities and Synthesis of Nitrated ANTA and NTO Derivatives
(2016)
Nitrated derivatives of 5-amino-3-nitro-1,2,4-triazole (ANTA)
and 3-nitro-1,2,4-triazol-5-one (NTO) were theoretically characterized with respect to their performance as high explosives and rocket propellants. The detonation ...
Experimental and numerical study of the fragmentation of expanding warhead casings by using different numerical codes and solution techniques
(2014)
There has been increasing interest in numerical simulations of fragmentation of expanding warheads in 3D. Accordingly there is a pressure on developers of leading commercial codes, such as LS-DYNA, AUTODYN and IMPETUS Afea, ...
The modus operandi of jihadi terrorists in Europe
(2014)
This article provides the most thorough overview yet of how jihadis have plotted terrorist attacks in Europe. Drawing on a database of 122 incidents, we review trends in weapon types, attack types and target types in the ...
Improved discretisation and linearisation of active tension in strongly coupled cardiac electro-mechanics simulations
(2012)
Mathematical models of cardiac electro-mechanics typically consist of three tightly coupled parts: systems of ordinary differential equations describing electro-chemical reactions and cross-bridge dynamics in the muscle ...
