Quantification of aerosol dispersal from suspected aerosol-generating procedures
(2021-12-06)Background Oxygen-delivering modalities like humidified high-flow nasal cannula (HFNC) and noninvasive positive-pressure ventilation (NIV) are suspected of generating aerosols that may contribute to transmission of disease ... -
Quantifying the tracking capability of space-based AIS systems
(2016)The Norwegian Defence Research Establishment (FFI) has operated three Automatic Identification System (AIS) receivers in space. Two are on dedicated nano-satellites, AISSat-1 and AISSat-2. The third, the NORAIS Receiver, ... -
The Queen Bees and the Women's Team - A contextual examination of enmity and friendship between military women
(2018)In several studies of women in the Norwegian Armed Forces, we have found an assertion that female groups are so riddled with conflicts and enmity that it is preferable to keep women few in number and mixed up ... -
Radar imager for Mars’ subsurface experiment—RIMFAX
(2020-11-03)The Radar Imager for Mars’ Subsurface Experiment (RIMFAX) is a Ground Penetrating Radar on the Mars 2020 mission’s Perseverance rover, which is planned to land near a deltaic landform in Jezero crater. RIMFAX will add a ... -
Radar sensitivity to human heartbeats and respiration
(2015)Human heartbeats and respiration can be detected from a distance using radar. This can be used for medical applications and human being detection. It is useful to have a system independent measure of how detectable the ... -
Radio-Frequency Interference Considerations for Utility of the Galileo E6 Signal Based on Long-Term Monitoring by ARFIDAAS
(2023)The extent to which navigation signals in the E6 band may be impacted by shared spectrum allocations might be underappreciated. This paper presents top-level observations from a multi-year international radio frequency ... -
A Radon-Transform-Based Image Noise Filter - With Applications to Multibeam Bathymetry
(2015)This paper describes a linear-image-transform-based algorithm for reducing stripe noise, track line artifacts, and motion-induced errors in remote sensing data. Developed for multibeam bathymetry (MB), the method has also ... -
Range and Doppler walk in DVB-T based Passive Bistatic Radar
(2010)This paper analyzes the effects of range and Doppler walk for a Digital Video Broadcast - Terrestrial based Passive Bistatic Radar of both simulated and experimental data. Range and Doppler walk cause energy dispersal ... -
Rapid Identification of Bacillus anthracis Spores in Suspicious Powder Samples by Using Matrix-Assisted Laser Desorption Ionization-Time of Flight Mass Spectrometry (MALDI-TOF MS)
(2013)Rapid and reliable identification of Bacillus anthracis spores in suspicious powders is important to mitigate the safety risks and economic burdens associated with such incidents. The aim of this study was to develop and ... -
The Rapidly Exploring Random Tree Funnel Algorithm
(2022-03-17)This paper shows the feasibility of combining robust motion primitives generated through the Sums Of Squares programming theory with a discrete Rapidly exploring Random Tree algorithm. The generated robust motion ... -
A Reactive Collision Avoidance Algorithm for Vehicles withUnderactuated Dynamics
(2017)This paper presents a reactive collision avoidance algorithm, which avoids both static and moving obstacles by keeping a constant avoidance angle between the vehicle velocity vector and the obstacle. In particular, we ... -
Reactive Collision Avoidance for Nonholonomic Vehicles in Dynamic Environments with Obstacles of Arbitrary Shape
(2021-11-01)Over the recent years, there has been an increasing interest in autonomous systems. Consequently, the problem of avoiding static and dynamic obstacles without human interference has gained a lot of attention. Avoiding ... -
Reactive Collision Avoidance for Underactuated Surface Vehicles using the Collision Cone Concept
(2021-08)Avoiding collisions is a crucial task for autonomous systems. Many strategies for avoiding obstacles have been proposed, yet the problem of having underactuated dynamics is rarely addressed in previous studies of collision ... -
Real-time anomaly detection in hyperspectral images using multivariate normal mixture models and GPU processing
(2009)Hyperspectral imaging, which records a detailed spectrum of light arriving in each pixel, has many potential uses in remote sensing as well as other application areas. Practical applications will typically require real-time ... -
Real-time georeferencing for an airborne hyperspectral imaging system
(2011)The paper describes the georeferencing part of an airborne hyperspectral imaging system based on pushbroom scanning. Using ray-tracing methods from computer graphics and a highly efficient representation of the digital ... -
Real-time PCR and NASBA for rapid and sensitive detection of Vibrio cholerae in ballast water
(2012)Transport of ballast water is one major factor in the transmission of aquatic organisms, including pathogenic bacteria. The IMO-guidelines of the Convention for the Control and Management of Ships’ Ballast Water and ... -
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 ... -
Reciprocity and the scattering matrix of waveguide modes
(2013)The implications of the Lorentz reciprocity theorem for a scatterer connected to waveguides with arbitrary modes, including degenerate, evanescent, and complex modes, are discussed. In general it turns out that a matrix ... -
The Recruiter’s Dilemma: Signaling and Terrorist Recruitment Tactics
(2013)How do terrorists recruit? We know much about the profiles and pathways of recruits, but little about the strategies and tactics of recruiters. Such procedures matter because they help determine who joins. I highlight a ...
