LINE EW-UAS link and network performance : passive performance analysis from the November 2015 flights
(2016-12-13)The communication capacity needs in the Norwegian Armed Forces (NAF) will increase in the coming years. Radios with high capacity often have strict requirements for Line-of-Sight (LoS). Unmanned Aerial Vehicles (UAVs) ... -
Linear motion of multiple superposed viscous fluids
(2019-04-16)In this paper the small-amplitude motion of multiple superposed viscous fluids is studied as a linearized initial-value problem. The analysis results in a closed set of equations for the Laplace transformed amplitudes of ... -
Lineærprogrammering og mixed integer programmering i strukturanalyser - grunnlag og erfaringer
(2006)The basic concept of optimisation – to find the best solution to a decision-problem, given a set of decisions, an objective and a set of constraints – is at the very hart of decision support and operations research. It ... -
Literature review of atmospheric contaminant transport offshore
(2023-11-17)In this report, we consider the atmospheric dispersion of possibly harmful contaminants from offshore accidents by doing a literature review on the subject. The atmospheric dispersion is mainly governed by the wind, which ... -
Literature review on estimating ice thickness
(2017-12-19)This report is a literature review on how to estimate ice thickness using satellite altimeter and satellite SAR. A presentation is given on ice, the properties of ice and on how sea ice and the ocean reflect back to the ... -
Literature review on ship and ice discrimination
(2017-11-14)Ice melting in the Arctic leads to more ship traffic, fishing, and new opportunities for oil searching and production in the High North. Maritime Domain Awareness (MDA) is of interest for Norway, and thus it is of ... -
Literature review on vessel detection
(2004)This report presents an overview of available literature on the subject of vessel detection in Synthetic Aperture Radar (SAR) imagery. The review was carried out as part of the EU-funded DECLIMS project, which is aimed at ... -
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 ...
