A containerised approach to labelled C&C traffic
(2022-01-24)A challenge for data-driven methods for intrusion detection is the availability of high quality and realistic data, with ground truth at suitable level of granularity to train machine learning models. Here, we explore a ... -
Content-based multimedia analytics: US and NATO research
(2018)The US and nations of the NATO Alliance are increasingly threatened by the global spread of terrorism, humanitarian crises/disaster response, and public health emergencies. These threats are influenced by the unprecedented ... -
Control Plane Performance in Tactical Software Defined Networks
(2019)Software Defined Networking can be beneficial in tactical networks to increase flexibility, provide programmability and to simplify management. The immense dynamics in tactical communication networks can, however, lead to ... -
Converting the Iranian heavy water reactor IR-40 to a more proliferation-resistant reactor
(2012)This article assesses the feasibility and benefits of converting the Iranian heavy water research reactor, IR-40, from using natural uranium to low-enriched uranium fuel. Based on neutronics calculations for a detailed ... -
Convex Variational Methods on Graphs for Multiclass Segmentation of High-Dimensional Data and Point Clouds
(2017)Graph-based variational methods have recently shown to be highly competitive for various classification problems of high-dimensional data, but are inherently difficult to handle from an optimization perspective. This ... -
Cooperative Caching in Space Information Networks
(2022-05-22)Members of a Low Earth Orbit (LEO) satellite group need to coordinate their activities in order to improve the quality and timeliness of the services provided to terrestrial clients. As a report from a work in progress, ... -
Correlation between sediment properties and seafloor characterization maps based on multibeam backscatter data from three regions off the coast of Norway
(2017)Multibeam echo sounder data from Kongsberg EM 1002 and EM 710 (70– 100 kHz) acquired between 2003 and 2014 were processed using QPS Fledermaus Geocoder Toolbox (FMGT) to produce backscatter mosaics and maps of estimated ... -
Correlations between sound speed and density in seabed sediment cores collected in Norwegian waters
(2022-08-08)In modelling of underwater sound propagation, knowledge about the seabed’s acoustic properties is essential, especially sound speed and density. These two properties are highly correlated, and standard empirical regressions ... -
Cost disease in defense and public administration: Baumol and politics
(2018)William Baumol’s model predicts a steady increase in relative public sector prices (or costs) because of the combination of slow productivity growth and wage growth similar to sectors wherein productivity is growing more ... -
Cost-Effective Flight Strategy for Aerial Thermography Inspection of Photovoltaic Power Plants
(2022-11-06)Thermography from unmanned aerial vehicles (UAV) is widely used for module condition surveys and defect detection in solar (photovoltaic) power plants. This article presents an optimized defect inspection procedure in which ... -
Country survey: military expenditure and defence policy in Norway 1970?2013
(2017)This article examines military expenditure and defence policy in Norway from 1970 to 2013. Until 1990 Norwegian military expenditure remained between 2.5 and 3.0 per cent of Gross Domestic Product (GDP). Despite constant ... -
A Critical Investigation of Proposed Electrostatic Corrections to Quantum Mechanical Volumes: The Importance of Variation and the Irrelevance of Imbalance
(2016)The crystal density of neutral and ionic molecular crystals is remarkably well approximated by the enclosed volume of molecular surfaces, where these surfaces are defined as regions of constant and small electron density. ... -
Critical thickness of MBE-grown Ga1-xInxSb (x < 0.2) on GaSb
(2009)Several Ga1−xInxSb layers, capped with 1 μm of GaSb, were grown on GaSb(0 0 1) substrates by molecular beam epitaxy in a Varian Gen II Modular system using either the conventional sample growth position with substrate ... -
Curing of Glycidyl Azide Polymer (GAP) diol using isocyanate, isocyanate-free, synchronous dual, and sequential dual curing systems
(2015)Glycidyl azide polymer (GAP) is an important energetic binder candidate for new minimum signature solid composite rocket propellants, but the mechanical properties of such GAP propellants are often limited. The mechanical ... -
The Dalton quantum chemistry program system
(2014)Dalton is a powerful general-purpose program system for the study of molecular electronic structure at the Hartree–Fock, Kohn–Sham, multiconfigurational self-consistent-field, Møller–Plesset, configuration-interaction, and ... -
Data loss prevention based on text classification in controlled environments
(2016)Loss of sensitive data is a common problem with potentially severe consequences. By categorizing documents according to their sensitivity, security controls can be performed based on this classification. However, errors ... -
Data-Driven Autocalibration for Swath Sonars
(2020-12-20)Sidelobes in swath sonar water column imagery can obscure targets of interest and create erroneous bottom detections. Differences between ideal and actual element responses limit the achievable sidelobe level for practical ... -
A decomposition solution approach to the troops-to-tasks assignment in military peacekeeping operations
(2019-09-20)This paper considers the Peacekeeping Troops-to-Tasks Problem (PTTP). The PTTP deals with assigning battlegroup resources to a set of tasks associated with a given peacekeeping mission. The tasks may be spread across several ... -
Deep temporal detection - A machine learning approach to multiple-dwell target detection
(2020)Detecting small targets, such as an Unmanned Aerial Vehicle (UAV) in high clutter and non-homogeneous environments is challenging for a radar system. Traditional Constant False Alarm Rate (CFAR) detectors have suboptimal ... -
Deep-ultraviolet picosecond flat-top pulses by chirp-matched sum frequency generation
(2012)Picosecond, flat-top, deep-UV pulses are needed to generate high-brightness electron beams to efficiently drive x-ray free electron lasers. Current metal photocathodes have low efficiency and therefore require high-energy ...
