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 ...
MODELING IRON ABUNDANCE ENHANCEMENTS IN THE SLOW SOLAR WIND
(2011)
We have studied the behavior of Fe ions in the slow solar wind, using a fluid model extending from the chromosphere to 1 AU. Emphasis is on elemental "pileup" in the corona, i.e., a region where the Fe density increases ...
O and Ne in an H-He Fast Solar Wind
(2011)
We have studied the abundances and ion fractions of O and Ne in an H-He fast solar wind with emphasis on gravitational settling in the chromosphere and corona. We use a time-dependent numerical model that spans the mid- ...
Scenario modelling with morphological analysis
(2017)
Scenarios can serve as points of reference in the future for decisions that we have to make today. Morphological analysis provides a structured method for ensuring consistency and relevance in scenario development. This ...
Evaluation of camouflage pattern performance of textiles by human observers and CAMAELEON
(2017)
Military textiles with camouflage pattern are an important part of the protection measures for soldiers. Military operational environments differ a lot depending on climate and vegetation. This requires very different ...
Analyses of the geolocation accuracy that can be obtained from shipborne sensors by use of time difference of arrival (TDOA), scanphase, and angle of arrival (AOA) measurements
(2010)
We have performed a theoretical study of the geolocation accuracy that can be obtained from
shipborne sensors by use of the localization methods: 1) time difference of arrival (TDOA), 2)
scanphase, and 3) angle of arrival ...
Safe application of lithium and lithium ion batteries
(2010)
The purpose of this report is to give a minimum of information for the safe use and assembling of
batteries. The requirements for battery safety circuits are described as well as the most common
use of devices such as ...
