Study of thermal instability of HMX crystalline polymorphs with and without molecular vacancies using reactive force field molecular dynamics
(2016)
The sensitivity of energetic materials can be identified by heat, friction, impact, shock, electrostatic charge, etc. A complexity of various factors may influence the sensitivity and among them are the crystal structure ...
Utviklingen av droner og EUs søken etter strategisk autonomi
(2017-12-05)
EUs rolle som sikkerhetspolitisk aktør får økende politisk oppmerksomhet. Den britiske
beslutningen om å tre ut av EU og USAs sviktende internasjonale ledervilje vil endre grunnlaget
for det transatlantiske sikkerhetsf ...
Generation of 1.5-octave intense infrared pulses by nonlinear interactions in DAST crystal
(2015)
Infrared pulses with large spectral width extending from 1.2 to 3.4 μm are generated in the organic crystal DAST (4-N, N-dimethylamino-4'-N'-methylstilbazolium tosylate). The input pulse has a central wavelength of 1.5 μm ...
Computing turbulence structure tensors in plane channel flow
(2016)
This paper is concerned with the computation of turbulence structure tensors in plane channel flow. It has been pointed out that the previously computed turbulence structure tensors, for this configuration, used an ...
Phase-coherent communications without explicit phase tracking
(2010)
Phase-coherent communications typically requires a reliable phase-tracking algorithm. An initial phase estimate with training symbols allows a receiver to compensate for a motion-induced Doppler shift. Following the training ...
L-alanine-induced germination in Bacillus licheniformis -the impact of native gerA sequences
(2014)
Background
L-alanine, acting through the GerA receptor, was recently found to be an efficient germinant in Bacillus licheniformis ATCC14580/DSM13.
Results
In this study, we show that several of 46 examined B. ...
Data loss prevention based on text classification in controlled environments
(2016)
Loss of sensitive data is a common problem with potentially severe consequences. By categorizing documents according to their sensitivity, security controls can be performed based on this classification. However, errors ...
A computational study of density of some high energy molecules
(2016)
The detonation pressure depends quadratically on the loading density of the explosives. A precise estimate of the density is thus crucial to decide if a novel energetic material is worth pursuing. In this work we investigate ...
The FESTER field trial
(2016)
An overview is given of the First European – South African Transmission ExpeRiment (FESTER), which took place in South Africa, over the False Bay area, centered around Simon’s Town. The experiment lasted from April 2015 ...
A Critical Investigation of Proposed Electrostatic Corrections to Quantum Mechanical Volumes: The Importance of Variation and the Irrelevance of Imbalance
(2016)
The crystal density of neutral and ionic molecular crystals is remarkably well approximated by the enclosed volume of molecular surfaces, where these surfaces are defined as regions of constant and small electron density. ...
