Mechanical properties of DPX-6 before and after accelerated ageing at 71 C
(2006)Uniaxial compression tests have been performed on cylindrical test items with L≈D of DPX-6 before and after ageing. Accelerated ageing was done at 71oC on test items wrapped in aluminium foil. Samples were taken out after ... -
Peacekeeping and the modernized Russian armed forces
(2007)Siden Sovjetunionens sammenbrudd har militærreform stått sentralt på den politiske agendaen i Kreml. Militærreformens uttalte siktemål har vært å omskape mobiliseringsforsvaret til et moderne forsvar med de strukturelementer ... -
LAMU tracker – a tracker for sensors with Large Angular Measurement Uncertainty
(2007)LAMU (Large Angular Measurement Uncertainty) trackeren har blitt utviklet for sensorer med stor vinkel-usikkerhet, altså stor målestøy for vinkelmålingen. Mange HF (High Frequency) radarer er eksempler på slike sensorer. ... -
A model for the burn velocity of tracers
(2006)In this report we perform a study of the burn velocity of tracer compositions. Both the burn velocity during flight and in static conditions is studied. In addition we present results for varying densities of the tracer ... -
AMEC Project 1.1-1: Design, Construction, and Commissioning into Test Operation of a Storage Pad for Transportable Metal-Concrete Containers for the Interim Storage of Russian Naval Spent Nuclear Fuel
(2007)Northwest Russia contains large quantities of spent nuclear fuel (SNF) from naval reactors that potentially threaten the environmental security of the surrounding Arctic Region. The majority of the SNF from the Russian ... -
Risikovurdering av tungmetallforurensning på en utendørs skytebane
(2000)Risk assessment of heavy metal pollution was carried out at an outdoor firing range at Sessvollmoen, Norway. The assessment is based on the supervisor published by SFT (Statens forurensningstilsyn). The results indicate ... -
Geomagnetic noise suppression in Overhauser magnetometer data - a comparative study
(2007)In this report we investigate data from three scalar Overhauser magnetometers w.r.t noise suppression. We use remote reference methods with and without filters, and obtain suppressions in the order of respectively 17-38dB ... -
A graphics-independent computer program for radio communications calculations
(2006)A simple program written in the C programming language is documented. The code is given the name CalcRadio and calculates the effects of radiowave propagation, antenna gain, interference and jamming. The program treats ... -
Static magnetic dipole detection - generalized matched filtering to Anderson functions
(2006)We propose a method for combined noise suppression and target detection for 3-axial magnetometer measurements. Vector linear prediction is used to whiten the noise, and matched filters are used for detection. In a case ... -
Determination of detonation velocity and plate dent properties fir DPX-6
(2006)M72 LAW (Light Antiarmour Weapon) has been redesigned with a new warhead for urban warfare. The new warhead is designed for combat of light buildings and therefore need an explosive filling that is optimized for this ... -
Determination of critical diameter for DPX-6
(2006)M72 LAW (Light Antiarmour Weapon) has been redesigned with a new warhead for urban warfare. The new warhead is designed for combat of light buildings and therefore needs an explosive filling that is optimized for this ... -
Studies of wear charactistics of three different gunpowder gases
(2006)In this report a study of the gun barrel wear characteristicsof three different gunpowders are performed. The three different gunpowders are: Bofors NC 1214 NEXPLO (NEXPLO), BOFORS NC 1214 EURENCO (EURENCO) and PB Clermont ... -
Waziristan - impact on the Taliban insurgency and the stability of Pakistan
(2006)This report takes a closer look at the struggles currently taking place in the Federal Administered Tribal Areas of Pakistan, bordering with Afghanistan. It provides an overview of some of the militant factions who are ... -
Hardness tests used to establish constitutive models
(2008)In this report a study of the hardness of different materials are performed theoretically and experimentally. The objective was to study whether the hardness test could be used to establish constitutive material models. We ... -
Observability at HF direction finding sites of scattering from wind farms - measurements at Smøla 2006
(2006)This report studies, on a general basis, whether wind farms may decrease the accuracy of direction finding systems in the HF (high frequency, 2-30 MHz) band, due to scattering from the wind turbine towers or blades. ... -
Variational multiscale turbulence modeling in a high-order spectral element method
(2006)One of the more promising recent approaches to turbulence modelling is the Variational Myltiscale Large Eddy Simulation (VMS LES) method proposed by Hughes et al.[Comp. Visual. Sci., vol 3, pp 47-59, 2000]. This method avoids ...
