Single-Cell Tracking of A549 Lung Cancer Cells Exposed to a Marine Toxin Reveals Correlations in Pedigree Tree Profiles
(2018)Long-term video-based tracking of single A549 lung cancer cells exposed to three different concentrations of the marine toxin yessotoxin (YTX) reveals significant variation in cytotoxicity, and it confirms the potential ... -
Single-point structure tensors in turbulent channel flows with smooth and wavy walls
(2019-10-06)A long-standing problem in turbulence modeling is that the Reynolds stress tensor alone is not necessarily sufficient to characterize the transient and nonequilibrium behaviors of turbulence under arbitrary mean deformation ... -
Skandinavias første jihadister
(2019-03-22)Nyoppdagede primærkilder viser et skandinavisk innslag blant afghanaraberne i 1980-årene. Jihadismen i nord er antakelig eldre enn tidligere antatt. -
Small state perspectives on learning, improvement, and institutionalization – a case study
(2021)This article describes and discusses the perspectives of a small state - Norway - on the innovation process accompanying the introduction of a new joint targeting concept and the practices associated with it. Most case ... -
Small-scale fire performance assessment of intumescent coatings on metal tubes containing ammonium nitrate. A stepping-stone towards their application as a fire safety measure on road transportation tanks?
(2021-11)Ammonium nitrate is used in vast amounts globally, first and foremost as a component of fertilizers and explosive formulations. This usage necessitates its transportation which, as for most hazardous materials, involves ... -
SMART II: Android apps, cloud computing and mobile device management as enablers for efficient operations
(2019-11-25)"SMART" { pervasive situational awareness at the individual soldier level { was a Concept Development and Experimentation (CD&E) project carried out in Norway during 2016. The concept being tested was the use of smart ... -
Smokeless GAP-RDX Composite Rocket Propellants Containing Diaminodinitroethylene (FOX-7)
(2017)Composite rocket propellants prepared from nitramine fillers (RDX or HMX), glycidyl azide polymer (GAP) binder and energetic plasticizers are potential substitutes for smokeless double-base propellants in some rocket motors. ... -
The social context of individual foraging behaviour in long-finned pilot whales (Globicephala melas)
(2014)Long-finned pilot whales (Globicephala melas) are highly social cetaceans that live in matrilineal groups and acquire their prey during deep foraging dives. We tagged individual pilot whales to record their diving behaviour. ... -
A socio-cognitive perspective on implementation and use of smart technology in the Norwegian home guard
(2019-11-25)The Norwegian Defence Research Establishment (FFI) has developed a communications concept for the Norwegian home guard (HV). This concept, called ”SMART” due to the emphasis on smart technologies, has been realized as a ... -
Software-Defined Underwater Acoustic Modems: Historical Review and the NILUS Approach
(2017)Flexible/adaptive acoustic modems that are reprogrammable/reconfigurable at all layers of the communication stack, either by a user or by means of autonomous decisions, are considered as an important enabler for interoperability ... -
Solar Wind from Coronal Funnels and Transition Region Lyalpha
(2005)Using a newly developed gyrotropic solar wind model that extends continuously from the mid-chromosphere to 1 AU and that accounts for radiative losses in the transition region, we have studied the difference between the ... -
Solving non-linear Boolean equation systems by variable elimination
(2019-08-17)In this paper we study Boolean equation systems, and how to eliminate variables from them while bounding the degree of polynomials produced. A procedure for variable elimination is introduced, and we relate the techniques ... -
Sonar scattering from the sea bottom near the Norwegian coast
(2017)High false alarm rates on active sonar systems in shallow waters is a well known problem which may be a limiting factor for the sonar performance. One way to reduce the false alarm rate is through supervised learning and ... -
Source Localization With Multiple Hydrophone Arrays via Matched-Field Processing
(2016)This paper considers approaches to combining information from multiple arrays in matched-field processing (MFP) for underwater acoustic source localization. The standard approach is to apply conventional MFP for each array ... -
The Space of Influence: Developing a New Method to Conceptualise Foreign Information Manipulation and Interference on Social Media
(2023-05)Foreign information manipulation and interference (FIMI) on social media is a fast- evolving threat to democracies. However, there is a growing need to systematically conceptualise the phenomenon. General Morphological ... -
Spaceborne Bistatic SAR Processing Using the EETF4 Algorithm
(2009)In this letter, the fourth-order extended exact transfer function (EETF4) is adapted for spaceborne bistatic synthetic aperture radar (SAR) processing. The problems with high squint and large bistatic Doppler centroid ... -
Sparse Phase Estimation and Processing of Independent Coherent Processing Intervals
(2017)Radars employing electronically steering arrays are capable of instantaneously altering the direction of the beam along with other parameters. This flexibility offers great opportunities to a radar as it may e.g. divide ... -
Sparse range-Doppler image construction with neural networks
(2020-06-11)The principles outlined by compressed sensing can permit a sensor to collect reduced amount of data and still reconstruct an exact outcome. This can for example be used to generate super-resolution sparse range-Doppler ... -
Spatial coherence of speckle for repeat-pass synthetic aperture sonar micronavigation
(2021-03-31)Accurate positioning of autonomous underwater vehicles is a major challenge. The long-term drift is problematic if global position updates are not available, and for applications such as repeat-pass interferometry and ...
