Bayesian seabed classification using angle-dependent backscatter data from multibeam echo sounders
(2014)Acoustical seabed classification is a technology for mapping seabed sediments. Processed multibeam sonar data yield the variation of the seabed scattering strength with incidence angle, and this paper examines the effect ... -
Beam shaping of high power laser diode bars
(2001)A technique for reshaping the highly astigmatic beam from a high-power laser diode bar by use of two parallel mirrors is studied theoretically and experimentally. It is found that the output from the 1 µm x 1 cm laser ... -
Beamforming of synthetic target signal acquired by the Atlantis PCL system
(2016-09-20)The passive coherent location system, Atlantis, is a test bed for digital beamforming at the Norwegian Defence Research Establishment (FFI). The system has functionality for real time direction of arrival (DoA) estimation. ... -
Behavior of captive herring exposed to naval sonar transmissions (1.0-1.6 kHz) throughout a yearly cycle
(2012)Atlantic herring, Clupea harengus, is a hearing specialist, and several studies have demonstrated strong responses to man-made noise, for example, from an approaching vessel. To avoid negative impacts from naval sonar ... -
Behavioral changes following PCB 153 exposure in the Spontaneously Hypertensive rat - an animal model of Attention-Deficit/Hyperactivity disorder
(2014)Background Attention-Deficit/Hyperactivity Disorder (ADHD) is a behavioral disorder affecting 3-5% of children. Although ADHD is highly heritable, environmental factors like exposure during early development to various ... -
Behavioral Responses of Captive Herring to Sonar Signals (1-1.6 kHz) of a Naval Frigate Throughout a Yearly Cycle
(2012)Atlantic herring, Clupea harengus, is a hearing specialist, and several studies have demonstrated strong responses to man-made noise, for example, from an approaching vessel. To avoid negative impacts from naval sonar ... -
Behavioral responses to predatory sounds predict sensitivity of cetaceans to anthropogenic noise within a soundscape of fear
(2022-03-21)As human activities impact virtually every animal habitat on the planet, identifying species at-risk from disturbance is a priority. Cetaceans are an example taxon where responsiveness to anthropogenic noise can be severe ... -
Behavioral side effects of prophylactic therapies against soman-induced seizures and lethality in rats
(2014)Four medical therapies previously shown to exert varying degrees of protection against a convulsant dose of soman were assessed for potential behavioral side effects in a novelty test. In Experiment 1, HI-6 (1-[([4-(amin ... -
Behavioural response studies of cetaceans to naval sonar signals in Norwegian waters - 3S-2011 cruise report
(2011-11-01)Marine mammals are sensitive to sound in their environment and there is a continuing need to quantify the sensitivity of the animals to behavioural disturbance, and determine how potential behavioural changes may affect ... -
Behavioural responses of cetaceans to naval signals in Norwegian waters - the 3S-2012 cruise report
(2012-11-01)Marine mammals are sensitive to sound in their environment and there is a continuing need to quantify the sensitivity of the animals to behavioural disturbance, in order to regulate the use of powerful anthropogenic sound ... -
Behavioural responses of cetaceans to naval sonar signals – the 3S-2013 cruise report
(2014-06-20)The 3S-projects is an international collaborative effort with the aim to investigate behavioral reactions of cetaceans to naval sonar signals, in order to establish safety limits for sonar operations. This report summarizes ... -
Behavioural responses of wild, spawning Atlantic cod (Gadus morhua L.) to seismic airgun exposure
(2023-03-11)Seismic airgun surveys to map petroleum deposits in the seabed may impact behaviour of marine animals over large distances. Understanding whether fish spawning behaviour is affected by this anthropogenic noise source is ... -
Bein i nesa : en antropologisk studie av kjønnsproblematikk på minesveiperen KNM Otra
(2010-02)Stortingsmelding nr. 36 (2006–2007) [1] understreker behovet for høyere kvinneandel i Forsvaret. På oppdrag fra Forsvarsdepartementet skal Forsvarets forskningsinstitutt (FFI) drive forskning på årskull for å identifisere ... -
Beitedyr på skyte- og øvingsfelt - eksponering og effekter av de ammunisjonsrelaterte metallene kobber og bly - en litteraturstudie
(2017-02-08)Forsvarets skyte- og øvingsfelt inneholder metallforurensinger som bly (Pb) og kobber (Cu) fra ammunisjon. Norske skyte- og øvingsfelt er sjelden inngjerdet og kan benyttes som utmarksbeite for husdyr. Det kan derfor ... -
Beitekvalitet i skyte- og øvingsfelt
(2010)Med tanke på risikovurderinger av sau som beiter i forurensede skyte- og øvingsfelt er det gjort en vurdering av hvordan Forsvarets aktivitet i disse feltene påvirker beitekvaliteten. Studien viser at dette er sterkt ... -
Bekjempelse av internasjonal terrorisme : fra militærmakt til utviklingshjelp
(2006)The present report provides an overview over different strategies of combating terrorism. It serves to clarify the conceptual basis for analyses in the TeTe2 project and can be used as a reference document that provides ... -
