Specification of functions for the Unison underwater warfare demonstrator
(2002)UNISON 2005 is a research and development program supporting the development of the next generation of combat systems for underwater warfare. The UNISON 2005 program is a co-operation between KDA, SIMRAD and FFI. The ... -
Specifying radiometric performance of hyperspectral and conventional cameras: A minimal set of independent characteristics
(2020)The radiometric performance of cameras is customarily characterized and specified in terms of component properties such as F-number and readout noise. This paper considers the camera as an integrated unit and derives ... -
Spectral characteristics of moist birch leaves and synthetic materials: experimental studies and evaluation of models
(2021-11-09)The optical depth of biomaterials and natural backgrounds varies with their environment and incoming light properties. Deciduous trees, for instance, have canopy thicknesses that vary significantly from one place to another. ... -
Spectral element benchmark simulations of natural convection in two-dimensional cavities
(2004)This report presents the results of spectral element simulations of natural convection in two-dimensional cavities. In particular, a detailed comparison is performed with the reference data recently described by Christon ... -
Spectral properties of multilayered oak leaves and a camouflage net: experimental measurements and mathematical modelling
(2021-09-21)The development of state-of-the-art surveillance technology forces nations to develop camouflage with advanced capabilities. Owing to the abundance and wide distribution of leaves, their spectral properties are often ... -
Spectral reflectance and transmission properties of a multi-layered camouflage net: Comparison with natural birch leaves and mathematical models
(2020-09-20)With improved specifications and capabilities of modern sensors and detectors, concealment is an increasingly challenging endeavor. Concealment from modern sensors requires advanced camouflage material that can provide low ... -
Spectral reflectance measurements of snow and snow covered objects: experimental studies compared with mathematical models
(2021-09-12)In this study, we have investigated reflectance spectra of different snow types under various conditions. Snow reflectance is interesting from a camouflage point of view as snow covers large land areas in many parts of the ... -
Sperm whales reduce foraging effort during exposure to 1-2 kH z sonar and killer whale sounds
(2016)The time and energetic costs of behavioral responses to incidental and experimental sonar exposures, as well as control stimuli, were quantified using hidden state analysis of time series of acoustic and movement data ... -
Spesifikasjon av ESM-demonstrator
(2000)The report contains a specification of an Electronic Support Measure (ESM) device for demonstration purposes. The device will be used by FFI to demonstrate modern passive positioning and identification techniques for the ... -
Spin scan tomographic array-based imager
(2014)This work presents a novel imaging device based on tomographic reconstruction. Similar in certain aspects to the earlier presented tomographic scanning (TOSCA) principle, it provides several important enhancements. The ... -
Spin scan tomographic imager
(2015)A novel imaging device based on tomographic reconstruction is presented. The imager is based on rotating an image of the scene onto a linear detector array, and then reconstructing a 2-dimensional image from the detector ... -
Spin-vibronic interaction induced reverse intersystem crossing: A case study with TXO-TPA and TXO-PhCz molecules
(2022-11-01)We highlight the important roles the direct spin–orbit (DSO) coupling, the spin-vibronic (SV) coupling, and the dielectric constant of the medium play on the reverse intersystem crossing (RISC) mechanism of TXO-TPA and ... -
Spredning av hvitt fosfor ved detonasjon av røykgranater med hvitt fosfor : sluttrapport
(2004)On assignment from Forsvarsbygg and Hærstaben, FFI has assessed the distribution of white phosphorus from the detonation of 155 mm and 81 mm smoke rounds. White phosphorus is a highly toxic material that is noxious to ... -
Spredning av stridsgasser. Kamuflasje
(Forsvarets forskningsinstitutt, 2004)Under arbeider i komitéer og KRB-utvalg (Kjemiske/Radiologiske/Biologiske) for vurdering av farene ved fiendtlig bruk av moderne kjemiske stridsmidler i Norge (i første rekke nyutviklede nervegasser), ble det klart at det ... -
Spørreundersøkelse blant vernepliktige i Hæren vedrørende norsk internasjonalt engasjement, verneplikt og verving
(2000)This report describes the results from a questionnaire among conscripts in the Norwegian Army 3 months into their service. The questionnaire addressed questions concerning recruitment to a professional Army unit, and ... -
Stabilisering av tungmetaller i jord
(2016-03-29)Flere tonn metaller og metalloider som kobber (Cu), bly (Pb), sink (Zn) og antimon (Sb) fra ammunisjon deponeres årlig i norske skytefelt. Metallene som deponeres vil, i tillegg til mekanisk slitasje, korrodere når de ... -
The stabilising effect by a novel cable cerclage configuration in long cephalomedullary nailing of subtrochanteric fractures with a posteromedial wedge
(2019-05-16)Background Clinical studies suggest that an adjunctive cerclage in intramedullary nailing of subtrochanteric fractures improves the outcome. Despite this, to what extent various cerclage configurations influences the ...
