Norge - en motvillig europeer i nord
(2023-03-23)Denne artikkelen spør hva Norge, som et lite land utenfor EU, kan gjøre for å styrke sin posisjon som en viktig aktør i nordområdene. Russlands angrep på Ukraina og en tiltakende arbeidsdeling mellom EU og Nato for ... -
Evaluating Publish/Subscribe Protocols for use in Constrained Networks
(2023-03-09)Considering the case of disaster relief and search and rescue operations, we can anticipate personnel operating with a total or partial lack of any pre-existing infrastructure. This means that ad hoc com- munication solutions ... -
Big Data Solutions on Tactical Infrastructure
(2022-12-01)In this paper, we discuss the need for explainable artificial intelligence (AI) in defense systems. Further, we elaborate on the need for Big Data solutions to support AI on tactical infrastructure, and discuss an ... -
Exact Two-Component TDDFT with Simple Two-Electron Picture-Change Corrections: X-ray Absorption Spectra Near L- and M-Edges of Four-Component Quality at Two-Component Cost
(2023-02-01)X-ray absorption spectroscopy (XAS) has gained popularity in recent years as it probes matter with high spatial and elemental sensitivities. However, the theoretical modeling of XAS is a challenging task since XAS spectra ... -
Optimizing the troops-to-tasks problem in military operations planning
(2015)In the planning of military operations, deciding who should do what, where, and when is crucial for the success of the operation. This troops-to-tasks analysis is a project scheduling problem closely related to the ... -
Towards Using Reinforcement Learning for Autonomous Docking of Unmanned Surface Vehicles
(2022-06-10)Providing full autonomy to Unmanned Surface Vehicles (USV) is a challenging goal to achieve. Autonomous docking is a subtask that is particularly difficult. The vessel has to distinguish between obstacles and the dock, and ... -
Spawning Atlantic cod (Gadus morhua L.) exposed to noise from seismic airguns do not abandon their spawning site
(2022-11-15)Seismic airgun surveys may disturb and displace fish at large ranges. If such displacement causes fish to abandon spawning grounds, reproductive success could be impacted. To investigate whether airgun sound causes cod ... -
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 ... -
A Performance Characteristic for Net Light Collection in Hyperspectral and Conventional Cameras: A*
(2022-12-09)The signal-to-noise ratio of modern cameras under normal operating conditions tends to be limited by “photon noise” originating from the random arrival of photons. For best signal-to-noise ratio, it is desirable to collect ... -
A risk-increasing safety strategy? Evaluating the Traditional Risk-mitigating Strategy in Dealing with Dumped Ammunition and Explosive Remnants of War
(2022-10-16)In Norway, hundreds of thousands of tonnes of explosive remnants of war remain in nature. It has always been recognized that the ordnance could represent a certain explosive risk if disturbed, and that some of the constituents ... -
Generalization and stabilization of exact scattering solutions for spherical symmetric scatterers
(2022-08-29)In a previous work the authors described a fast high-fidelity computer model for acoustic scattering from multi-layered elastic spheres. This work is now extended with a scaling strategy significantly mitigating the problem ... -
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. ... -
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 ... -
Collision Avoidance for Underactuated Surface Vehicles in the Presence of Ocean Currents
(2022-11-29)This paper considers the problem of collision avoidance for surface vehicles moving under the influence of ocean currents. The vehicles we consider have underactuated dynamics, where the vehicle cannot directly control its ... -
Freezing Unicast Paths in Sensor Swarms
(2022-09-22)Drone swarms have great potential to convey sensor information. However, a swarm may have a very high degree of topology dynamics. This impedes the sensor data distribution from the sensor node to consumers which are ... -
Compact multimodal multispectral sensor system for tactical reconnaissance
(Society of Photo-Optical Instrumentation Engineers (SPIE), 2022-09-30)Multispectral imaging is an attractive sensing modality for small unmanned aerial vehicles (UAVs) in numerous military and civilian applications such as reconnaissance, target detection, and precision agriculture. Cameras ... -
A Cloud-based experimentation and analysis framework for services at the tactical edge
(2022-09-22)In this paper we present an experimentation and analysis framework that utilizes a public cloud infrastructure for most of the experimentation environment but also supports interaction with services installed on servers ... -
Jamming and Jamming Mitigation for Selected 5G Military Scenarios
(2022-09-22)This paper presents jamming and jamming mitigation techniques, which can be used in relation to emerging military systems based on fifth-generation (5G) technology. Nowadays, 5G technology provides incremental improvements ... -
