Ship-of-opportunity noise inversions for geoacoustic profiles of a layered mud-sand seabed
(2019-04-30)This paper considers the use of broadband noise from a ship-of-opportunity in statistical inference for estimating geoacoustic parameters of a layered mud-sand seabed model via trans-dimensional (trans-D) Bayesian matched-field ... -
Shock attenuation by porous materials
(2015-03-24)Shock waves from explosions can do great damage to humans, buildings and other structures. Protective measures may therefore be useful to attenuate the effect of the shock waves. Porous materials have traditionally been ... -
Shock attenuation experiments using a Hopkinson bar method : summary of experimental results
(2009)Close-in attenuation of the pressure wave from a detonation is desirable in several applications. Porous materials are often assumed to have good shock damping properties. In this report an experimental set-up using a ... -
Shock sensitivity testing of Octols
(2008)Octol 60/40 and 70/30 (HMX/TNT) have been tested with regard to shock sensitivity in Intermediate Scale GAP test. Both compositions were cast filled into the test tubes. An average density of 98.1% of TMD was obtained ... -
Should I Stay or Should I Go? Explaining Variation in Western Jihadists' Choice between Domestic and Foreign Fighting
(2013)This article studies variation in conflict theater choice by Western jihadists in an effort to understand their motivations. Some militants attack at home, whereas others join insurgencies abroad, but few scholars have ... -
Signal environment mapping of the Automatic Identification System frequencies from space
(2016)This paper presents received signal strength data recorded by the NORAIS Receiver on the four VHF channels allocated to the use of the Automatic Identification System (AIS). The NORAIS Receiver operated on-board the Columbus ... -
Signalrepresentasjoner for automatisk talegjenkjenning
(2005)In this report we give an overwiev of methods for front-end processing of speech signals for automatic speech recognition (ASR) that are described in the litterature. The most common representation of speech in this ... -
Signatur- og atmosfæremodeller for bruk i det infrarøde spektralområdet
(1999)The objective for the project: electronic warfare for the air force, protection against IR-guided missiles, is to develop concepts for protection based on tactic, flares and ir-jammers. To obtain tbis, missiles, targets ... -
Sikker anvendelse av litiumbatterier
(2010-01)Rapporten tar sikte på å gi et minimum av bakgrunn for sikker bruk av batterier, herunder hvilke sikringsmekanismer man kan forvente i cellene og hvilke tiltak man selv må ivareta. En beskrivelse av bruken av de viktigste ... -
Sikkerhet i Voice over IP og andre multimediasesjoner basert på SIP og RTP
(2012-06-27)”Voice over IP” (VoIP), også kjent som IP-telefoni, er telefoni over pakkebaserte nettverk, slik som Internet. Hovedårsakene til utbredelsen av VoIP er at en unngår å ha et eget nett for formidling av tale og at VoIP kan ... -
Sikkerhet og sårbarhet i elektroniske samfunnsinfrastrukturer : refleksjoner rundt regulering og tiltak
(2007)Rapporten tar utgangspunkt i arbeidet med en serie med analyser og studier som i hovedsak er gjennomført i BAS-prosjektserien på FFI. Arbeidet har i stor grad vært rettet inn mot å identifisere og analysere tiltak for å ... -
Sikkerhetsarkitektur for Forsvarets informasjonsinfrastruktur - en innledende studie av rammeverk og begreper
(2017-07-14)Mange nye kapabiliteter som ønskes realisert i Forsvaret, forutsetter ny funksjonalitet i informasjonsinfrastrukturen. Men for å oppnå ønsket operativ evne, må tilstrekkelig sikkerhet være på plass for å beskytte mot ... -
