Acoustic seabed classification using QTC IMPACT on single-beam echo sounder data from the Norwegian Channel, northern North Sea
(2013)Sediment mapping is important for understanding the physical processes, the impact of human activity, and the conditions for marine life on the seabed. For this purpose, the seabed classification tool QTC IMPACT analyses ... -
Active spacecraft potential control investigation
(2014)In tenuous plasma the floating potential of sunlit spacecraft reaches tens of volts, positive. The corresponding field disturbs measurements of the ambient plasma by electron and ion sensors and can reduce micro-channel ... -
Adapting OLSR for WSNs (iOLSR) Using Locally Increasing Intervals
(2012)Proactive link state routing protocols, popular within the Mobile Ad hoc NETwork framework, have not been as successful in wireless sensor networks. This is mainly due to the extensive energy usage by control traffic ... -
Adaptive phase estimation filter in long range synthetic aperture sonar interferometry
(2023-05-15)Synthetic aperture sonar (SAS) interferometry is a technique for very high resolution imaging and mapping of the seabed. In SAS interferometry, the seabed depth estimation performance is a function of the system, the ... -
Adaptive suppression of smart jamming with FDA permutation
(2022-05-03)By adding a frequency increment to the carrier frequency of the pulses transmitted from an antenna array, it becomes possible to make the beam dependent on both frequency and range. This is called a frequency diverse ... -
Advice from the Scientific Advisory Board of the Organisation for the Prohibition of Chemical Weapons on riot control agents in connection to the Chemical Weapons Convention
(2018-12-19)Compounds that cause powerful sensory irritation to humans were reviewed by the Scientific Advisory Board (SAB) of the Organisation for the Prohibition of Chemical Weapons (OPCW) in response to requests in 2014 and 2017 ... -
Agile requirements handling in a service-oriented taxonomy of capabilities
(2016)To get to grips with information systems portfolio development, strategic decisions tend towards service orientation and cloud deployment. Functionality should be presented as services that can be consumed from secure ... -
Al-Qaida in the Islamic Maghrib’s Expansion in the Sahara: New Insights from Primary Sources
(2020-09-24)Although originating in Algeria, AQIM and its allies had by 2012 become so entrenched in the Sahel that they were in de-facto control of vast swathes of territory in northern Mali. This article explains how and why GSPC/AQIM ... -
All Molecular Surfaces are Equal: Demanding Invariance of Predictions in Linear Single-Variable Models
(2016)The molecular surface has been suggested to be a region of the molecule where information of non-covalent intermolecular interactions is present. Many workers have pursued this idea by constructing models based on statistical ... -
All solid-state spectral broadening: An average and peak power scalable method for compression of ultrashort pulses
(2016)Spectral broadening in bulk material is a simple, robust and low-cost method to extend the bandwidth of a laser source. Consequently, it enables ultrashort pulse compression. Experiments with a 38 MHz repetition rate, 50 ... -
Analysis of detection performance of incoherent range walk compensation for passive radar
(2015)This paper analyzes the performance of an incoherent range walk compensation method for passive radar systems. The method utilizes the velocity information in the range-Doppler map, and no detection before compensation ... -
Analysis of samples of high explosives extracted from explosive remnants of war
(2022-10-10)Millions of tonnes of dumped ammunition and explosive remnants of war remain in nature both on land and at sea. It is well known that the ordnance could represent a definite explosive risk if disturbed, and that some of ... -
Anisotropic scattered data interpolation for pushbroom image rectification
(2014)This paper deals with fast and accurate visualization of pushbroom image data from airborne and spaceborne platforms. A pushbroom sensor acquires images in a line-scanning fashion, and this results in scattered input data ... -
Anisotropy and shear-layer edge dynamics of statistically unsteady,stratified turbulence
(2015)Direct numerical simulation data of an evolving Kelvin-Helmholtz instability have been analyzed in order to characterize the dynamic and kinematic response of shear-generated turbulent flow to imposed stable stratification. ... -
Anonymous Tokens with Public Metadata and Applications to Private Contact Tracing
(2022-10-22)Anonymous single-use tokens have seen recent applications in private Internet browsing and anonymous statistics collection. We develop new schemes in order to include public metadata such as expiration dates for tokens. ... -
Ansar al-Sharia in Libya: An Enduring Threat
(2017)Ansar al-Sharia in Libya (ASL) is one of the most powerful jihadi groups in Libya and it might, in fact, represent a more significant long-term threat than IS’ provinces in Libya. However, there are few recent studies of ... -
Antenna Processing Optimization for a Colocated MIMO Radar
(2016)In a practical colocated MIMO radar design case, there will often not be a free choice of locations for single element antennas. Antenna parts may be available as rectangular arrays of antenna elements located on tiles, ... -
An application of a combined framework to set the future direction of the Norwegian Home Guard
(2020-02-17)In 2017, the Norwegian Ministry of Defence and the Norwegian Home Guard commissioned a research project to help set a future identity and direction for the reserve-based Home Guard. Using a combination of frameworks, we ... -
Architectural work for modeling and simulation combining the NATO Architecture Framework and C3 Taxonomy
(2016)To provide modeling and simulation functionality as services is strategically leveraged in the defense domain and elsewhere. To describe and understand the context, the ecosystem, wherein such services are used and ... -
