Norway, NATO and cyber defense
(2014-07-10)NATO is the cornerstone of Norwegian security policy, and has in recent years intensified its efforts relating to the cyber domain. Cyber defense has gained increased attention in Norway as well, and the Norwegian Armed ... -
Norwegian defence reforms of the 1990s
(2002)This report gives an overview of the Norwegian Defence Reforms of the 1990s focussing on defence concept evolution, the planning process, implementation issues, funding, time horizon for planning and lessons identified. ... -
Norwegian long-term defence analysis - a scenario- and capability-based approach
(2020-10-21)The Norwegian Defence Research Establishment (FFI) supports the political and military leadership of Norwegian defence in their long-term defence planning. In this report, we describe and review the method FFI uses to ... -
Not focussing on whether it's a spout or a handle : an anthropological study on even gender balance among conscripts in a Norwegian Air Force battalion
(2017-05-10)The Norwegian Air and Missile Defence Battalion at 138th Air Wing at Ørland airbase was chosen for an experiment between August 2014 and June 2016 on the initiative of the Air Force. Leaders in the Air Force wanted to ... -
A novel headspace sampler for field detection of chemical warfare agents and simulants connected to a commercial ion mobility detector
(2016)A rapid and simple sampling technique for use in conjunction with commercial ion mobility spectrometric detectors is described. The technique may be used for the detection of chemical warfare agents in the field. A plastic ... -
A Novel IoBT Security Assessment Framework: LoRaWAN Case Study
(2020)The Internet of Things (IoT) is interesting because this potentially disruptive technology can also be used as a low-cost approach to augment information in military systems. This makes following IoT trends important ... -
A Novel Method of Predicting Site DependentSpecific Rain Attentuation of Millimeter Radio Waves
(2003)There is a need for validation and improvement of propagation prediction methods for the safe design and operation of millimeter radio communication systems. At this frequency range, propagation related degradation is ... -
NSAT-1: nye momenter vedrørende kooperative overvåkningssystemer, flerfrekvent sensor samt havbølgers innvirkning på deteksjon og dekning
(2001)This report complements the NSAT-1 Phase-A Report with a discussion of three important topics. These are: (1) The emerging cooperative maritime surveillance systems. (2) The possibility of a dual-band NSAT sensor for ... -
Nuclear weapons capabilities and doctrines in North Korea
(2019-02-18)Det nordkoreanske atom- og missilprogrammet har hatt en akselerert utvikling under Kim Jong‑un. Vi har undersøkt offisielle nordkoreanske uttalelser om kjernevåpenbruk og analysert dem i en doktrinekontekst. Videre har ... -
Nuclear weapons – worldwide situation 2021
(2021-09-14)This report is based on open sources and provides an overview of the current status and recent developments in the nuclear weapons arsenals of the world’s nine nuclear-weapon possessing states. The brief sections on each ... -
Nucleation and propagation of thermomagnetic avalanches in thin-film superconductors (Review Article)
(2018)Stability of the vortex matter—magnetic flux lines penetrating into the material—in type-II superconductor films is crucially important for their application. If some vortices get detached from pinning centres, the energy ... -
Nullutslippsforsvaret – en mulighetsstudie av klimavennlig teknologi for Forsvaret
(2023-07-05)Norge må gjennom en krevende, men nødvendig, omstilling til et nullutslippssamfunn. Olje og gass tar før eller siden slutt, og samfunnet må innrette seg mot nullutslipp så raskt som mulig for å unngå katastrofale ... -
Numerical modeling of single-layered piezoelectric elements
(2007)The focus of this report is on numerical simulation of piezoelectric materials. One example of such a material is quartz. By applying a pressure load to a piezoelectric material, electricity is generated – the so-called ... -
Numerical modelling of short pulse shock initiation of ultrafine Hexanitrostilbene (HNS)
(2023-09-15)The study of short duration shock pulses is relevant in many high-energetic applications. One such application is the initiation of insensitive high explosives, often preferred as booster charges in military and civilian ... -
Numerical prediction of long-range sound propagation - parametric uncertainty and atmospheric models
(2014-04-09)This short report is concerned with two related subtopics in long-range acoustical noise prediction: Atmospheric modelling and parametric uncertainty. It consists of summaries of recent research articles from the outdoor ... -
Numerical simulation of light armour piercing ammunition against ceramics
(2005)Using the hydrocode Autodyn we perform numerical simulations of penetration into various combinations of ceramic armour and backing material. In particular we look at the penetration performance of two common 7.62 x 51 ... -
Numerical simulation of light armour piercing ammunition against steel
(2005)Numerical simulations using the hydrocode Autodyn of two different armour piercing projectiles are performed against steel and ceramic targets. The results are compared with some experimental data available. A major problem ... -
Numerical simulations of flow-induced vibrations on Orion P-3C
(2003)The radome mounted on the Orion P-3C has a significant adverse impact on the performance of the aircraft. Measurements have revealed low-frequency vibrations so severe that operational restrictions have been imposed. ... -
Numerical simulations of particle dispersion in an urban area
