Predicting acoustic dose associated with marine mammal behavioural responses to sound as detected with fixed acoustic recorders and satellite tags
(2019-03-08)To understand the consequences of underwater noise exposure for cetaceans, there is a need for assessments of behavioural responses over increased spatial and temporal scales. Bottom-moored acoustic recorders and satellite ... -
Predicting Basic Military Performance for Conscripts in theNorwegian Armed Forces
(2017)The Norwegian Armed Forces have made major changes to the enlistment and selection system for conscripts in recent years. In this article, the predictive validity of various selection criteria for military performance is ... -
Predicting False Alarm Rates for High-Resolution Antisubmarine Warfare Sonars in a Cluttering Environment Prone to False Alarm Rate Inflation
(2019-09-13)Operation of high-resolution, broadband, antisubmarine warfare sonars in littoral waters is challenging, since the presence of sea mounts, underwater ridges, and other topographic features causes increased false alarm ... -
Predicting Near-Time Satellite Signal Attenuation at Ka-band Using Tropospheric Weather.
(2018-12-10)There are satellite communication applications where it is desirable to predict near time (e.g. 2 to 12 h) propagation losses at Ka-band due to hydrometeor precipitation. We present results from a project investigating the ... -
Predicting scalar coupling constants via machine learning
(2021-12-22)Over the preceding decade, machine learning techniques have been successfully applied in several fields of research, including the prediction of chemical properties of atoms and molecules. Whereas conventional quantum ... -
Prediction of concrete penetration using Forrestals formula
(2000)The various existing empirical formulas for predicting penetration into concrete targets are seen to give different results. Explaining the difference is difficult since most of the original empirical data behind the ... -
Preliminary assessment of the vertical release of liquefied chlorine inside a depression
(2009)Toxic industrial chemicals (TICs) are used in most places and can pose a threat due to accidents, terror, or sabotage. Many of the most common TICs are gasses at ambient atmosphere, such as chlorine, ammonia, and sulfur ... -
Preliminary numerical simulation of the dispersion of chlorine vapour in a mock urban environment for the Jack Rabbit II field trials
(2016-02-02)The release and dispersion of toxic industrial chemicals as a result of accidents, terrorism, or sabotage represent a possible hazard for life and health. Such chemicals are often transported and stored as condensed ... -
Preparation and characterisation of epoxy/alumina polymer nanocomposites
(2013)The effect of adding nanosized alumina fillers of both fibre-like and spherical shapes to an epoxy polymer has been investigated. The alumina was dispersed in the epoxy hardener using two different sonication techniques. ... -
Preparation of biological contaminated samples for chemical analysis
(2009)FFI has established laboratory facilities in order to receive and analyze samples containing a mixture of chemical, biological and radiological (CBR) agents, so-called “mixed samples”. Detailed procedures are needed to ... -
Presisjonsstyrte våpen i de senere års konflikter
(2004)This report gives an overview and a discussion of the development and utilisation of long-range precision guided munitions in recent military operations – starting with Desert Storm in 1991. The open literature has been ... -
Prestasjonsbasert logistikk (PBL) - muligheter og utfordringer
(2011-11-01)Prestasjonsbasert logistikk, eller Performance-Based Logistics (PBL), er et relativt nytt konsept for understøttelse av militære systemer. En grunntanke i PBL er endringen fra den tradisjonelle transaksjonsbaserte formen ... -
Pretreatment and prophylaxis against nerve agent poisoning: are undesirable behavioral side effects unavoidable?
(2016)The threat of chemical warfare agents like nerve agents requires life saving measures of medical pretreatment combined with treatment after exposure. Pretreatment (pyridostigmine) may cause some side effects in a small ... -
Prinsipper for en bærekraftig forsvarsøkonomi
(2015-10-08)I denne rapporten diskuteres prinsipper for en bærekraftig forsvarsøkonomi. Prinsippene er allmenne og kan vektes ulikt avhengig av hvilken forsvarsstruktur de anvendes på. I rapporten defineres bærekraftig forsvarsøkonomi ... -
Prinsipper for norsk avskrekking – en operasjonsanalytisk tilnærming
(2019-05-08)Forsvarets oppgave nummer 1 er å «Sikre troverdig avskrekking med basis i NATOs kollektive forsvar». I denne rapporten diskuterer vi hva som kan ligge i «troverdig avskrekking» ved å bruke operasjonsanalyse som verktøy. ... -
Pro-inflammatory cytokines in cystic glioblastoma: A quantitative study with a comparison with bacterial brain abscesses. With an MRI investigation of displacement and destruction of the brain tissue surrounding a glioblastoma
(2022-07-29)Cystic glioblastomas are aggressive primary brain tumors that may both destroy and displace the surrounding brain tissue as they grow. The mechanisms underlying these tumors’ destructive effect could include exposure of ... -
Probabilistic estimation of merchant ship source levels in an uncertain shallow-water environment
(2021-11-13)The estimation of ship source levels (SSLs) in shallow-water environments can be complicated by sound interaction with the seabed. Uncertainty in seabed properties influences SSL estimates, and it is of interest to mitigate ... -
