Segmentation of PMSE data using random forests
(2022-06-22)EISCAT VHF radar data are used for observing, monitoring, and understanding Earth’s upper atmosphere. This paper presents an approach to segment Polar Mesospheric Summer Echoes (PMSE) from datasets obtained from EISCAT VHF ... -
Seismic exploration noise reduction in the marginal ice zone
(2014)A sonobuoy field was deployed in the Marginal Ice Zone of the Fram Strait in June 2011 to study the spatial variability of ambient noise. High noise levels observed at 10–200 Hz are attributed to distant (1400 km range) ... -
Selected Issues of QoS Provision in Heterogenous Military Networks
(2014)Tactical ad-hoc networks are evolving today towards complex heterogeneous networks in terms of architecture, protocols and security. Due to the difference in network resources and reliability, end-to-end quality of service ... -
A selection of data from measurements of C4 detonations at Finnskogen in 1994 - test case C1
(2007)Denne rapporten er en del av et pågående arbeid ved Forsvarets forskningsinstitutt (FFI) for å forbedre Forsvarsbygg (FB) sin evne til å estimere støynivået rundt forsvarets skytefelt. FFI sitt arbeid er en del av et ... -
Selective adsorption of lead, copper and antimony in runoff water from a small arms shooting range with a combination of charcoal and iron hydroxide
(2015)Metals and metalloids from ammunition residues at small arms shooting ranges leach into the soil and surrounding watercourses and may pose a threat to exposed wildlife and humans. To reduce the potential impact of heavy ... -
Selekteres de riktige personene til dagens Forsvar? -beskrivelse av dagens seleksjonsordning til førstegangstjenesten
(2019-09-09)I Norge har vi kjønnsnøytral verneplikt (allmenn verneplikt) som vil si at alle unge menn og kvinner må delta i seleksjonsprosessen til førstegangstjeneste. Førstegangstjenesten er en lovpålagt tjeneste hvor hensikten er ... -
Semantic Service Discovery for Interoperability in Tactical Military Networks
(2010)Interoperability, both inter- and intra-nation, is a main concern when attempting to fully realize NATO Network Enabled Capabilities (NNEC). The NNEC vision implies an information infrastructure that supports prioritized access ... -
Semantic service discovery in dynamic environments
(2007)Denne rapporten samler tre publiserte artikler innenfor fagområdet “service discovery” i dynamiske omgivelser. Samlet gir artiklene en god introduksjon til fagfeltet, samtidig som de peker på hva som mangler for å forbedre ... -
Semantic technologies
(2007)Semantiske teknologier kan beskrives som teknologier som gjør det mulig å bygge mer adaptiv og effektiv software ved å utnytte meningsinnholdet i den tilgjengelige informasjonen. I FFIprosjektet Semantini, semantiske ... -
Semantic wiki - collaboration, semantics & semi-structured knowledge
(2010)Wikis are collaboration tools and characteristic examples of Web 2.0 utilisation of technology. Users participate to generate content and maintain the quality of information within the wiki. Information is contained in ... -
Semantikkbasert informasjonsforvaltning for Forsvaret - sluttrapportering av aktiviteten på semantiske teknologier i FFI-prosjekt Informasjons- og integrasjonstjenester i INI
(2016-12-19)Rapporten oppsummerer forskningsaktiviteten på semantiske teknologier i FFI-prosjekt 1277 – Informasjons- og integrasjonstjenester i INI. Delaktivitetens oppgave var å studere hvordan semantiske teknologier kan brukes ... -
Semi-active suspension systems using magneto-rheological fluids
(2008)For a given vehicle, the suspension system isolates the passengers and payload from shock and vibration. In addition, the system also enables the wheels to maintain contact with the surface, thereby affecting stability and ... -
Sensemaking and decision-making in a joint military context: The role of translating, verifying and prioritizing information
(2018)This article, based on fieldwork during a military exercise in Norway, analyzes how new technology is used in joint operations by military personnel and how it is connected to sense-making and decision-taking. The authors' ... -
Sensitivity of input parameters to modelling of atmospheric transmission of long-wave infrared radiation at sea under warm and humid conditions
(2018)A joint Australian-Norwegian eld trial (Osprey) was held in February 2018 in Darwin, Australia. The objective of this trial was to measure IR transmission properties of the atmosphere in a marine environment under warm and ... -
Sensitivity of LYBINs transmission loss due to variations in sound speed
(2006)This study is motivated by the Sea Acceptance Test 2 (SAT2) to be made sometime in 2006. The testing of the new Norwegian Frigates sonar system will involve use of the acoustic ray trace model, LYBIN. The study reveals ... -
Sensitivity to changes in sound speed on passive bearing and range estimation
(2003)A passive towed array can easily measure the bearing to a target. Range can be found by at least two methods; measurements of time of arrival differences at three spaced hydrophone or hydrophone clusters or triangulation ... -
