Evaluation of Two Path Following Controllers for an Ackermann Off-road Vehicle in Winter and Summer Conditions
(2021-04-02)Off-road driving can be a challenging task with rapid changes in the driving conditions, terrain and vehicle behavior. For off-road autonomous vehicles, it is important to be robust to these changes, and parts of this ... -
Evaluering av effektiviseringsarbeidet i forsvarssektoren – evaluering etter første året i langtidsplanen for perioden 2017–2020
(2018-07-02)I langtidsplanen for perioden 2017–2020 skal forsvarssektoren effektivisere omlag 1,8 mrd. kroner innen utgangen av 2020. Alle etatene har derfor fått i oppdrag å arbeide strukturert med kontinuerlig forbedring og ... -
Evaluering av Forsvarets logistikksystem – utvikling og anvendelse av et nytt metodisk rammeverk
(2020)Tidligere studier ved Forsvarets forskningsinstitutt har påpekt gap i Forsvarets logistikksystem. Hensikten med denne studien har vært å undersøke om Forsvarets logistikksystem, ved bruk av strategiske partnere, påvirker ... -
Evaluering av HF-modemer og flerfrekvenssystemer basert på kanalmålinger på høye breddegrader
(1998)The high latitude HF channel has been measured and characterised in terms of Doppler spread, delay spread and signal-to-noise ratio. This is done by the Doppler And Multipath Sounding Network developed(DAMSON) by DERA ... -
Evaluering av RAZOR™-instrument for identifisering av biologiske trusselstoffer
(2013-08-07)Ved en biologisk hendelse er det viktig å undersøke tilstedeværelse av biologiske trusselstoffer så raskt som mulig og identifisere dem, samt å avklare om de biologiske trusselstoffene utgjør en reell trussel. PCRteknikken er ... -
Evaluering av støy fra håndvåpen ved måleanlegget på FFI
(2015-12-14)De ti siste årene har FFI publisert om lag 40 rapporter og artikler om akustisk støy fra våpen. Denne rapporten beskriver metoden vi benytter for å bestemme den akustiske kildestyrken til et våpen. Noe er nytt, men vi ... -
Evaluering av tre typer autoinjektor-regimer mot nervegassforgiftning
(2011-12-15)Forsvaret er utstyrt med akuttmedisinske motmidler som har til formål å redusere skader på mennesker og å øke overlevelse etter nervegasseksponering. Dette er legemidler som skal benyttes både profylaktisk og i oppfølgende ... -

Everything you wanted to know about material testing but were afraid to ask
(2003)The theory behind various methods of material testing is reviewed. We look in detail at static triaxial testing with a GREAC cell and dynamic testing with the Split Hopkinson Bar and Flyer plate. In particular, we ... -
Evolving a Repertoire of Controllers for a Multi-function Swarm
(2018)Automated design of swarm behaviors with a top-down approach is a challenging research question that has not yet been fully addressed in the robotic swarm literature. This paper seeks to explore the possibility of using ... -
Exact 3D scattering solutions for spherical symmetric scatterers
(2018)In this paper, exact solutions to the problem of acoustic scattering by elastic spherical symmetric scatterers are developed. The scatterer may consist of an arbitrary number of fluid and solid layers, and scattering with ... -
Exact Two-Component TDDFT with Simple Two-Electron Picture-Change Corrections: X-ray Absorption Spectra Near L- and M-Edges of Four-Component Quality at Two-Component Cost
(2023-02-01)X-ray absorption spectroscopy (XAS) has gained popularity in recent years as it probes matter with high spatial and elemental sensitivities. However, the theoretical modeling of XAS is a challenging task since XAS spectra ... -
Examination of yawed impact using a combined numerical and analytical approach
(2003)Performing sensitivity studies using 3D-hydrocodes have normally been an extremely time consuming process and still remains so even though computer speed continues to increase. To overcome this problem, a combined analytical ... -
Examples of operational capability of NSAT-1 - phase-B report
(2003)NSAT-1 is a Norwegian micro satellite primarily for surveillance of the Norwegian waters. Four scenarios are described and simulated to study the coverage and revisit times for NSAT-1. The results shows that the Norwegian ... -
