Operativ bruk av ikke-dødelige våpen
(2003)The report gives a brief introduction to non-lethal weapons in general and FFI's work in the field. This is followed by short descriptions of a number of scenarios suitable for the use of non-lethal weapons. -
Operativ nytte av ensemblevarsling for hav
(2014-06-02)I krigføring under vann er kunnskap om lydutbredelsen viktig, og en riktig beskrivelse av den vertikale lydhastighetsprofilen er essensielt for beregninger av lydutbredelsen. Målte lydhastighetsprofiler vil alltid være ... -
Operative beslutningsstøttetjenester - fremtid NBF
(2005)This report describes a conceptual solution for information and integration services for Command and Control in a short-term view (2008). We have used a long-term vision for 2014 as a basis, and from this derived a ... -
Oppbemanning av Forsvaret i koronaens tid - en samfunnsøkonomisk analyse
(2021-04-23)I april 2020 la regjeringen frem sitt forslag til ny langtidsplan for Forsvaret (LTP) for perioden 2021–2024. Forslaget til LTP la opp til en gradvis oppbemanning av Forsvaret med 550 årsverk frem mot 2024. Koronapandemien ... -
Opplinjering av oppsett for fotoluminesensmåling
(2014-11-12)Permanent oppsett for måling av fotoluminesens fra halvlederprøver er plassert på eget optikkbord på rom 203D/185. Når en laserstråle med passende intensitet og bølgelengde treffer en halvleder vil elektron-hullpar dannes ... -
Oppvarming av litium- og litiumionceller
(2006)Lithium cells may for safety purposes be equipped with safety vents, shut down separators and various types of fuses. In this work lithium primary cells, lithium ion cells and a lithium ion polymer battery block have been ... -
Oppvarming ved laserstråling – første forsøk med enkle konstruksjonsmaterialer
(2024-02-15)Prosjektet «Laservåpen og beskyttelse» innenfor forskningsprogrammet «Luftvern, ubemannede luftsystemer og laser» går ut på å utvikle høyeffektlasere som mottiltak mot innkommende prosjektiler, droner og liknende. Denne ... -
oProbe - an OMNeT extension module
(2007)OMNeT++ er et programvarebasert rammeverk for å bygge simuleringsmodeller av datanett, se www.omnetpp.org. Denne rapporten beskriver et programvareprosjekt kalt oProbe som utvider OMNeT++ med en modul for statistisk analyse. ... -
Optical limiting properties and z-scan measurements of carbon disulfide at 2.05 μm wavelength
(2016)Nonlinear and optical limiting properties of carbon disulfide (CS 2 ) are characterized at 2.05 μm wavelength using a 𝑄 -switched Ho:YLF laser with high pulse energy. The nonlinear refractive index of CS 2 is measured ... -
Optical limiting properties of carbon disulfide at 2.05μm wavelength
(2016)Several types of infrared sensors are based on sensitive focal plane arrays. In such sensors, the intensity will typically increase by a factor ~107 at the focal plane, compared to the intensity of the incoming radiation. ... -
Optical parametric master oscillator and power amplifier for efficient conversion of high-energy pulses with high beam quality
(2004)We describe a system for parametric conversion of high-energy, Q-switched laser pulses from 1.064 µm to 2.1 µm in KTiOPO4. High beam quality and efficiency are obtained by use of a two-stage system: An optical parametric ... -
Optical parametric oscillators with high pulse energy and beam quality
(2010)A new method for obtaining high beam quality from high pulse energy optical parametric oscillators (OPOs) is demonstrated. By using different nonlinear crystals that have walk-off in orthogonal directions but are type 2 ... -
Optimal classification of standoff bioaerosol measurements using evolutionary algorithms
(2011)Early warning systems based on standoff detection of biological aerosols require real-time signal processing of a large quantity of high-dimensional data, challenging the systems efficiency in terms of both computational ... -
