A comparison of AUTODYN and RSPH on two-dimensional shock waves problems
(2009)It is important, both to the military and civilian community, to be able to predict the strength and propagation pattern of shock waves generated from the detonation of high explosives. This report documents a comparative ... -
A comparison of measurements and predictions of HF groundwave propagation
(2005)The field-strength of HF groundwave was logged for 6 different locations in the south-eastern part of Norway. Results were compared to models that take terrain elevation and ground conductivity/permittivity as input ... -
Comparison of RADARSAT and IKONOS satellite images - detection and visibility of man-made objects
(2001)This report compares the visual appearance and detection of different man-made objects in an area close to Bergen city in Norway using IKONOS (1 m resolution) and RADARSAT (9 m resolution) images respectively. The results ... -
Comparison of results from some chemical dispersion models and hazard prediction and assessment tools
(2010)Dispersion models and hazard prediction and assessment software tools are used to assess consequences from dispersion of hazardous materials, such as toxic chemicals. Such tools can be employed during and after an event ... -
Comparison of sound propagation codes: Milstøy, BNoise and a PE-method
(2009)Ranges for military training must ensure that noise reaching neighbors is kept at an acceptable level. In Norway, strict noise limits are set by the authorities. To comply with these regulations, the Norwegian Defence ... -
Comparison of thermal runaway initiation methods for a cylindrical Li-ion cell
(2021-08-30)Li-ion batteries have become an important part of our daily life in applications as different as cell phones and electric ferries. High energy density is one of the factors for the successful market penetration of this ... -
Compressed sensing og sparse rekonstruksjon i radarsammenheng
(2020-09-25)Denne rapporten gir en kort gjennomgang av de viktigste prinsippene bak compressed sensing og vurderer noen mulige anvendelser i radarsammenheng. Compressed sensing er en metodikk som kan anvendes for å samle inn og ... -
Compressive properties of PBXN-5 and PBXW-11 before and after ageing at 60 °C for 3 and 6 months
(2008)PBXW-11 and PBXN-5 have been tested in uniaxial compressive test at room temperature according to STANAG 4443. PBXW-11 shows moderate changes in compressive mechanical properties due to ageing for up to 6 months at 60oC. ... -
Computational fluid dynamics simulations of local wind in large urban areas
(2020-09-29)The present report details the methodology and parameters used for high-fidelity computational fluid dynamics (CFD) simulations of wind in large urban areas. In particular, a 150 km2 area of Oslo is used as an example, ... -
Computational fluid dynamics simultations of flow and dispersion in the aerosol test chamber
(2012-10-19)This report presents findings from computer simulations of the air flow and the dispersion of aerosols inside a rectangular 12 m3 Aerosol Test Chamber. Methodologically, the Large Eddy Simulation approach is used, in ... -
Computational modeling of health effects from indoor dispersion of airborne biological and chemical agents
(2019-03-20)Biologisk eller kjemisk terror, der biologiske eller kjemiske stoffer benyttes for å skade eller ta livet av sivile, er en trussel med store potensielle konsekvenser. Flere kjemiske og biologiske trusselstoffer kan være ... -
Computational studies of impact sensitivity in energetic plasticizers – using DFT on BuNENA, MeNENA and DINA
(2023-10-02)Energetic materials are key constituents in rocket propellants. Modern solid rocket propellants contain energetic plasticizers, whose purpose is to adjust propellant properties such as thermal stability, energy content, ... -
Concept for trusted binding of metadata to data
(2013-02-27)Information exchange is a critical part of military operations. Information flows between domains are traditionally managed by air gaps and manual review-and-release procedures. More efficient information flow mechanisms ... -
