BAKTRAK: Backtracking drifting objects using an iterative algorithm with a forward trajectory model
(2012)The task of determining the origin of a drifting object after it has been located is highly complex due to the uncertainties in drift properties and environmental forcing (wind, waves, and surface currents). Usually, the ... -
Band structures and Z2 invariants of two-dimensional transition metal dichalcogenide monolayers from fully relativistic Dirac-Kohn-Sham theory using Gaussian-type orbitals
(2023-06-02)Two-dimensional (2D) materials exhibit a wide range of remarkable phenomena, many of which owe their existence to the relativistic spin-orbit coupling (SOC) effects. To understand and predict properties of materials ... -
Bandwidth optimizations for standards-based publish/subscribe in disadvantaged grids
(2012)NATO has identified Web services as a key enabler for its network enabled capability. Web services facilitate interoperability, easy integration and use of commercial off-the-shelf components, and while request/response-based ... -
A Bayesian Network Approach to Evaluating the Effectiveness of Modern Mine Hunting
(2021-10-29)This paper describes a novel technique for estimating how many mines remain after a full or partial underwater mine hunting operation. The technique applies Bayesian fusion of all evidence from the heterogeneous sensor ... -
Bayesian seabed classification using angle-dependent backscatter data from multibeam echo sounders
(2014)Acoustical seabed classification is a technology for mapping seabed sediments. Processed multibeam sonar data yield the variation of the seabed scattering strength with incidence angle, and this paper examines the effect ... -
Behavior of captive herring exposed to naval sonar transmissions (1.0-1.6 kHz) throughout a yearly cycle
(2012)Atlantic herring, Clupea harengus, is a hearing specialist, and several studies have demonstrated strong responses to man-made noise, for example, from an approaching vessel. To avoid negative impacts from naval sonar ... -
Behavioral changes following PCB 153 exposure in the Spontaneously Hypertensive rat - an animal model of Attention-Deficit/Hyperactivity disorder
(2014)Background Attention-Deficit/Hyperactivity Disorder (ADHD) is a behavioral disorder affecting 3-5% of children. Although ADHD is highly heritable, environmental factors like exposure during early development to various ... -
Behavioral Responses of Captive Herring to Sonar Signals (1-1.6 kHz) of a Naval Frigate Throughout a Yearly Cycle
(2012)Atlantic herring, Clupea harengus, is a hearing specialist, and several studies have demonstrated strong responses to man-made noise, for example, from an approaching vessel. To avoid negative impacts from naval sonar ... -
Behavioral responses to predatory sounds predict sensitivity of cetaceans to anthropogenic noise within a soundscape of fear
(2022-03-21)As human activities impact virtually every animal habitat on the planet, identifying species at-risk from disturbance is a priority. Cetaceans are an example taxon where responsiveness to anthropogenic noise can be severe ... -
Behavioral side effects of prophylactic therapies against soman-induced seizures and lethality in rats
(2014)Four medical therapies previously shown to exert varying degrees of protection against a convulsant dose of soman were assessed for potential behavioral side effects in a novelty test. In Experiment 1, HI-6 (1-[([4-(amin ... -
Behavioural responses of wild, spawning Atlantic cod (Gadus morhua L.) to seismic airgun exposure
(2023-03-11)Seismic airgun surveys to map petroleum deposits in the seabed may impact behaviour of marine animals over large distances. Understanding whether fish spawning behaviour is affected by this anthropogenic noise source is ... -
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 ... -
Big Five Personality Profiles in the Norwegian Special Operations Forces
(2020-05-05)This study is the first to report on Big Five personality traits of employees in the Norwegian military Special Operations Forces (NORSOF). Three research questions were formulated for this study, aiming to investigate (1) ... -
Biological significance of sperm whale responses to sonar: Comparison with anti-predator responses
(2016)A key issue when investigating effects of anthropogenic noise on cetacean behavior is to identify the biological significance of the responses. Predator presence can be considered a natural high-level disturbance stimulus ... -
Bispyridinium compounds inhibit both muscle and neuronal nicotinic acetylcholine receptors in human cell lines
(2015)Standard treatment of poisoning by organophosphorus anticholinesterases uses atropine to reduce the muscarinic effects of acetylcholine accumulation and oximes to reactivate acetylcholinesterase (the effectiveness of which ... -
Bitstream radar waveforms for generic single-chip radar
(2017)A Digital-to-Time converter (DTC) based on static CMOS multiplexers is presented, achieving a time resolution of 65 ps consuming 0.5 mW. The DTC relies on gate delay for programmability, ensuring robustness, linearity and ... -
'Bomb-making for beginners': Inside an al-Qaida e-learning course
(2013)This study explores how terrorists utilize the Internet to learn bomb-making skills. Unlike previous studies, it does not focus on assessing the quality of online bomb recipes. Rather, it discusses the efforts being made ... -
Bond strength and performance of optical fibre Bragg gratings sensors embedded in composite patch repairs for military aircraft
(2016)Structural health monitoring (SHM) systems are recognized as a key element in a modern and efficient approach to structural lifecycle management. With novel applications of advanced materials, such as extensive use of ... -
Botulism outbreaks in natural environments - an update
(2014)Clostridium botulinum comprises a diverse group of botulinum toxin-producing anaerobic rod-shaped spore-forming bacteria that are ubiquitously distributed in soils and aquatic sediments. Decomposition of plants, algae, and ... -
Brain infection with Staphylococcus aureus leads to high extracellular levels of glutamate, aspartate, γ-aminobutyric acid, and zinc
