Nucleation and propagation of thermomagnetic avalanches in thin-film superconductors (Review Article)
(2018)Stability of the vortex matter—magnetic flux lines penetrating into the material—in type-II superconductor films is crucially important for their application. If some vortices get detached from pinning centres, the energy ... -
Moral outrage: The generative power of political emotions.
(2018)Moral outrage has until now been conceptualized as a call to action, a reaction to injustice and transgressions, and a forceful motor for democratic participation, acts of civil disobedience, and violent and illicit action. ... -
A New Distributed Localization Algorithm Using Social Learning Based Particle Swarm Optimization for Internet of Things
(2018)Emerging applications in the Internet of Things (IoT) will depend on the accurate location of thousands of deployed sensors. However, accurate localization of deployed sensors nodes is a classical optimization problem which ... -
Autonomous, Cooperative UAV Operations Using COTS Consumer Drones and Custom Ground Control Station
(2018)The benefits of using UA Vs for inexpensive aerial surveillance and survey have been widely accepted, and UAVs are routinely assisting humans performing ISR operations. While large countries and well-funded military ... -
Estimating output mix effectiveness: An applied scenario approach for the Armed Forces
(2019)The ability of public sector policy makers to prioritize has a huge impact on the effectiveness of public service provision. Public services can take the form of final outputs demanded by consumers or of intermediate outputs ... -
Use of n-vector for radar applications
(2018)This paper aims to alert the radar community about the benefits of using n-vector for representing global horizontal position. Unlike other alternatives, n-vector position calculations are simple, vectorized and exact at ... -
Connecting the dots in counterterrorism: The consequences of communication setting for shared situation awareness and team performance
(2018)Shared situation awareness (SSA) is critical for counterterrorism teams. We examined whether a rich media condition (co‐located face to face) and a lean media condition (distributed email) differentially influence SSA at ... -
Improved correction methods for measuring altitude by Radar and Barometer
(2018)Geometric altitude of air targets may be found from radar or barometric measurement. However, radar rays are affected by changes in refractive index gradients which result in non-normal bending of rays. Similarly, precision ... -
Guidelines for using animal models in blast injury research
(2018)Blast injury is a very complex phenomenon and frequently results in multiple injuries. One method to investigate the consequences of blast injuries is with the use of living systems (animal models). The use of animals ... -
A 3D Reactive Collision Avoidance Algorithm for Underactuated Vehicles
(2018)This paper presents a 3D reactive collision avoidance algorithm for vehicles with underactuated dynamics. The underactuated states cannot be directly controlled, but are controlled indirectly by steering the direction of ... -
Image-aided inertial navigation for an Octocopter
(2018)A typical unmanned aerial system combines an Inertial Navigation System (INS) and a Global Navigation Satellite System (GNSS) for navigation. When the GNSS signal is unavailable, the INS errors grow over time and eventually ... -
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 ... -
Supporting artificial intelligence with artificial images
(2018)Infrared (IR) imagery is frequently used in security/surveillance and military image processing applications. In this article we will consider the problem of outlining military naval vessels in such images. Obtaining these ... -
A 3D Reactive Collision Avoidance Algorithm for Nonholonomic Vehicles
(2018)This paper presents a 3D reactive collision avoidance algorithm for vehicles with nonholonomic constraints. The algorithm steers the heading and pitch angle of the vehicle in order to maintain a constant avoidance angle ... -
An Integral Line-of-Sight Guidance Law with a Speed-dependent Lookahead Distance
(2018)This paper presents an algorithm that makes an underactuated marine vehicle follow a straight line path while in the presence of a constant ocean current. When following the path, the vehicle maintains a desired surge speed ... -
Automating Event-B invariant proofs by rippling and proof patching
(2019-01-02)The use of formal method techniques can contribute to the production of more reliable and dependable systems. However, a common bottleneck for industrial adoption of such techniques is the needs for interactive proofs. We ... -
Terrain referenced navigation using sand dunes and sand ripples in presence of tides
(2018)We investigated using terrain referenced navigation in shallow water in the presence of unknown tide, with an autonomous underwater vehicle equipped with a high resolution bathymetric sensor. The mission area had both ... -
Investigation of new orexin 2 receptor modulators using in silico and in vitro methods
(2018)The neuropeptides, orexin A and orexin B (also known as hypocretins), are produced in hypothalamic neurons and belong to ligands for orphan G protein-coupled receptors. Generally, the primary role of orexins is to act as ... -
Simplified energy landscape for modularity using total variation
(2018)Networks capture pairwise interactions between entities and are frequently used in applications such as social networks, food networks, and protein interaction networks, to name a few. Communities, cohesive groups of nodes, ...
