China's nuclear weapons programme
(2013-07-15)China has been a nuclear weapons power since it conducted its first nuclear test explosion in 1964. This means that China is one of the five states that are allowed to keep a nuclear weapons arsenal under the Treaty of ... -
Classification of acoustically stable areas using empirical orthogonal functions - examination of stability methods
(2011-11-08)Overview and control of the oceanographic and acoustic variations are very important in underwater warfare. We have developed a method for dividing an area into smaller subareas that can be represented by a single vertical ... -
Cloud influence on maritime surveillance by an optical satellite
(2016-03-03)Disturbing clouds may be a showstopper when planning a maritime surveillance satellite with an optical sensor. When the probability of clouds in any place is in the range of 75 %, it is indeed important to know where the ... -
Cloud-based decision support system for planning military operations
(2020-02-21)When planning a military operation, it is important to explore possibilities and understand consequences of the plan. To this end, wargaming can be used for assessing possible courses of action (COA) for own and enemy ... -
Cluster weapons - military utility and alternatives
(2008)This report is made through the sponsorship of the Royal Norwegian Ministry of Foreign Affairs. Its purpose is to get an overview of the military utility of cluster munitions, and to find to which degree their capacity ... -
Clustering evaluation for deinterleaving
(2013-02-23)Deinterleaving is a fundamental step in a lot of processing in ESM and radar systems, enabling users and/or client programs to focus on data from a single emitter at a time, rather than a mixture of data from several ... -
A collection of oceanographic and geoacoustical data in Vestfjorden - obtained from the MILOC survey Rocky Road
(2002)A brief overview of oceanographic and geoacoustic data from the Vestfjorden area is given. The overview is based on data collected during the MILOC survey Rocky Road, which took place during 1992-95. -
Combustion of RS-41
(2000)The pyrotechnic composition RS-41, a mixture of 49 wt.% KClO4, 49 wt.% Al/Mg and 2 wt.% Calcium Resinate, is an important ingredient in the MP (Multipurpose) ammunition. RS-41 placed in the front of the projectile ignites ... -
"Common sense is not that common" : krysskulturelle kommunikasjonskollisjoner : utfordringer i internasjonal krisehåndtering
(2008)Denne rapporten fokuserer på sivilmilitært samarbeid i internasjonal krisehåndtering, og den beskriver og analyserer en del av de utfordringene som ligger i feltet krysskulturell kommunikasjon og samhandling. Rapporten ... -
Communication signal generation and automatic classification with detection of unknown formats using neural networks
(2004)The performance of algorithms for signal classification is often characterized according to their ability to correctly classify various signals belonging to a set of known signal formats. However, in a non-co-operative ... -
COMPACT project - hydro burst testing of impact damaged four-inch pressure vessels
(2013-09-20)Twelve four-inch pressure vessels made of carbon fibre reinforced plastic (CFRP) have been produced at FFI. The applied material system is a carbon fibre reinforced prepreg system, TCR UF3325-95/M30SC. The vessels have ... -
Comparison between analytical shock mechanic solutions and numerical solutions from the autodyn hydro code
(2004)Numerival codes, i.e. Autodyn are widely used for simulations purpose during impact and penetration of prosjectiles into targets. To check the validity of the simulations during shock compression we first study the axiomatic ... -
Comparison of 294 nm and 355 nm excitation wavelengths in UVLIF standoff detection of biological aerosols released in a semi-closed chamber
(2012-02-07)FFI has previously developed a lidar for standoff detection of biological aerosols based on ultraviolet laser induced fluorescence, using an excitation wavelength at 355 nm. A 294 nm laser source has been developed and ... -
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 ...
