Livet i hegemonens skygge - en småstats sikkerhetslogikk
(2007)The security policies of small states after the Cold War have not been a central area of research. The security logic of the European small states covered by this study depends heavily on the geopolitical settings and ... -
Localization of a merchant ship by means of striations in a lofargram
(2005)In low frequency passive sonar a lofargram is a common presentation form for time varying spectral data. A target may emit narrow frequency lines and broadband noise. Depending upon the transmission channel, the target ... -
Localized mesosphere-stratosphere-troposphere radar echoes from the E region at 69 degrees N: Properties and physical mechanisms
(2011)We present the first observations, to our knowledge, of a new class of high-latitude mesosphere-stratosphere-troposphere radar echoes from the E region as observed with the Arctic Lidar Observatory for Middle Atmosphere ... -
A logical characterisation of SPARQL federation
(2014)The paper provides a logical characterisation of distributed processing of SPARQL queries. The principal notion analysed is that of a distribution scheme; a pair consisting of an evaluation rule and a distribution function. ... -
Logistics as a security policy tool – exploring motivations for allied support in the case of Norway
(2022-12-10)How, if at all, might logistics serve as a security policy tool for increasing the likelihood of allied support? Over the last few years, European NATO allies such as Germany and France have expressed uncertainty about the ... -
Logistikk og støtte - en beskrivelse av hvilke tjenester som inngår i begrepet
(2008)Logistikk- og støttetjenester utgjør det ressursmessige grunnlaget som den militære virksomheten hviler på, og er avgjørende for at militære operasjoner skal kunne gjennomføres. Logistikk fungerer som en styrkemultiplikator, ... -
Long-range tropospheric transport of uranium and plutonium weapons fallout from Semipalatinsk nuclear test site to Norway
(2013)A combination of state-of-the-art isotopic fingerprinting techniques and atmospheric transport modelling using real-time historical meteorological data has been used to demonstrate direct tropospheric transport of radioactive ... -
Long-Term Measurements of Tropospheric Scintillation at Very Low Elevation Angles - Initial Analysis
(2022-05-11)Four years of scintillation measurements at very low elevation angles at Kjeller, Norway are analyzed and compared with the ITU-R model. One year is at Ka band with an elevation angle of 3°, and three years are of simultaneous ... -
A LoRa Mesh Network Asset Tracking Prototype
(2020)Long Range (LoRa) is a low powered wide area communications technology, which uses radio frequencies in the industrial, scientific and medical (ISM) band to transmit data over long distances. Due to these properties, i.e., ... -
Low frequency models for littoral sound propagation - a comparison between a finite element model and a wave number integration model
(2005)Two different strategies for modeling sound propagation, exploring the Helmholz equation, in underwater acoustics are presented and compared, a nite element and a wave number integration model. The numerical models ... -
Low-Complexity Adaptive Sonar Imaging
(2016)We have studied the low-complexity adaptive (LCA) beamformer in active sonar imaging. LCA can be viewed as either a simplification of the minimum variance distortionless response (MVDR) beamformer, or as an adaptive extension ... -
Low-energy enhancement of nuclear γ strength and its impact on astrophysical reaction rates
(2014)An unexpected enhancement in the low-energy part of the γ-strength function for light and medium-mass nuclei has been discovered at the Oslo Cyclotron Laboratory. This enhancement could lead to an increase in the neutron-capture ... -
Low-frequency long-range atmospheric noise propagation modelling with the PE method
(2014-02-06)This note is part of an effort to improve numerical prediction of acoustic noise from Norwegian military practice ranges. The focus is on low-frequency, long-ranging sound. A Parabolic Equation method for sound propagation ... -
LTAMC experiments - assessment of culture and organizational and group processes in a simulated mission
(2008)This report presents the analyses of the data from the NATO HFM RTG – 138 Leader and team adaptability in multinational coalitions (LTAMC) experiments with a focus on organization, group processes, culture, communication, ... -
LTE for Military Communication - Business Models and Vulnerabilities
(2017)This document outlines security issues concerning military use of LTE. It illustrates implications of different business models, and outlines vulnerabilities that decision makers should be aware of in order to protect the ... -
LTE i Forsvaret - sårbarheter knyttet til ulike forretningsmodeller
(2016-04-18)LTE (Long Term Evolution) er en kommersiell 4G bredbåndsteknologi som har blitt svært utbredt. Rapporten omhandler sikkerhet ved bruk av LTE i Forsvaret. Den gir en oversikt over risikoområder som bør studeres nærmere, ... -
Luftbåren smitte av virale luftveisinfeksjoner fra et aerosolfysisk perspektiv
(2020-06-16)Luftbåren smitte foregår gjennom at infeksiøst materiale følger med dråper av ulik størrelse ut fra verten gjennom respiratoriske aktiviteter som pust, tale, sang, host eller nys. For de vanlige aktivitetene som pusting, ... -

Luftvern og sårbarhet av flystasjoner. Olje, gass og norsk sikkerhet
(Forsvarets forskningsinstitutt, 2004)Luftvern har vært et tilbakevendende analysetema på FFI. Særlig med flystasjonsluftvern tok det lang tid og flere analyser før man fikk tatt noen endelig beslutning om valg av luftvernsystem. Alt så tidlig som på 1960-tallet ... -
LYBIN 5.0 : interface description
(2009)The acoustic ray trace model LYBIN is a well established and frequently used sonar prediction model owned by the Norwegian Defence Logistic Organisation. The model is used onboard navy vessels as well as in training ...
