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 ... -
Realising benefits in public IT projects: A multiple case study
(2022-12-13)Information Technology (IT) investments in the public sector are large, and it is essential that they lead to benefits for the organisations themselves and wider society. While there is evidence suggesting a positive ... -
Wargaming for the Purpose of Knowledge Development: Lessons Learned from Studying Allied Courses Of Action
(2022-09-19)We present a series of four wargames intended to improve our ability to analyze the alliance aspect of Norwegian military operations. We discuss the objectives, the set-up, and the lessons learned. The wargames proved to ... -
Practical Jamming of a Commercial 5G Radio System at 3.6 GHz
(2022-09-22)Fifth-generation (5G) mobile technology has attracted interest from armed forces worldwide due to its many new possibilities for communication. Military operations may face threats in the electromagnetic spectrum, such as ... -
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 ... -
NATO Core Services profiling for Hybrid Tactical Networks -Results and Recommendations
(2021-07-21)The NATO Research Task Group IST-150 "NATO Core Services profiling for Hybrid Tactical Networks" had Federated Mission Networking (FMN) as the main context and motivation for its work. IST-150 intended to investigate Core ... -
Understanding the Threat of Nuclear, Biological and Chemical Warfare
(2021)Weapons of mass destruction are not merely Cold War relics. Recent years have seen the use of biological and chemical agents in the United States, Syria, Malaysia and the United Kingdom. The faltering of strategic arms ... -
Effects of Cultural Diversity on Trust and its Consequences for Team Processes and Outcomes in Ad Hoc Distributed Teams
(2011)This quasi-experimental study explores trust as a mediator, explaining how cultural diversity may affect team processes and outcomes in distributed ad hoc teams. Data were collected both through self-report and direct ... -
