MRTD: Man versus machine
(2018)We present Minimum-Resolvable Temperature Difference (MRTD) curves obtained by letting an ensemble of observers judge how many of the six four-bar patterns they can “see” in a set of images taken with different bar-to-background ... -
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 ... -
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 ... -
Content-based multimedia analytics: US and NATO research
(2018)The US and nations of the NATO Alliance are increasingly threatened by the global spread of terrorism, humanitarian crises/disaster response, and public health emergencies. These threats are influenced by the unprecedented ... -
Propionate enters GABAergic neurons, inhibits GABA transaminase, causes GABA accumulation and lethargy in a model of propionic acidemia
(2018)Propionic acidemia is the accumulation of propionate in blood due to dysfunction of propionyl-CoA carboxylase. The condition causes lethargy and striatal degeneration with motor impairment in humans. How propionate exerts ... -
A field-based method for evaluating thermal properties of static and mobile camouflage
(2018)Reliable and realistic methods for assessment of thermal infrared signature properties for military purposes are important. With a basis in ongoing developments of imaging technologies, especially towards mass markets, ... -
Tactical Router Interoperability: Concepts and Experiments
(2018)Interoperability on the lower tactical levels, e.g. in a multinational battalion or team, poses challenges because of the high degree of mobility and limited data capacity at the tactical edge. Enabling such multi-national ... -
Measurement of point spread function for characterization of coregistration and resolution: Comparison of two commercial hyperspectral cameras
(2018)For spectral cameras, the spatial resolution and coregistration of bands are important performance characteristics. The paper discusses how these can be quantified in a way that is relevant for the spectroscopic processing ... -
Field-Testing of High-Level Decentralized Controllers for a Multi-Function Drone Swarm
(2018)This paper describes the results of initial field testing of a high-level decentralized controller for a swarm of multi-rotor drones. This controller allows the intuitive implementation of a wide variety of swarm behaviors. ... -
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 ... -
Hierarchical path planning for walking (almost) anywhere
(2018)Computerized path planning, not constrained to transportation networks, may be useful in a range of settings, from search and rescue to archaeology. This paper develops a method for general path planning intended to work ... -
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 ... -
Guidelines for conducting epidemiological studies of blast injury
(2018)Blast injuries are often caused by more than one mechanism, do not occur in isolation, and typically elicit a secondary multi-system response. Research efforts often do not separate blast injuries caused by blast waves ... -
Fully adaptive radar for track update-interval control
(2018)A fully adaptive radar framework has been proposed in recent publications, and this paper will implement the framework in an adaptive update rate application for a tracking radar. A cost function is developed to balance ... -
Sensitivity of input parameters to modelling of atmospheric transmission of long-wave infrared radiation at sea under warm and humid conditions
(2018)A joint Australian-Norwegian eld trial (Osprey) was held in February 2018 in Darwin, Australia. The objective of this trial was to measure IR transmission properties of the atmosphere in a marine environment under warm and ... -
Toward an architecture and data model to enable interoperability between federated mission networks and IoT-enabled smart city environments
(2018)The emergence of smart city initiatives in many areas of the world has led to rapid development and proliferation of Internet of Things (IoT) technologies. Successful deployments of IoT have resulted in the military looking ... -
Evolving a Repertoire of Controllers for a Multi-function Swarm
(2018)Automated design of swarm behaviors with a top-down approach is a challenging research question that has not yet been fully addressed in the robotic swarm literature. This paper seeks to explore the possibility of using ... -
Using Open Standards for Utilizing IoT Sensors in a Smart City Scenario
(2018)Although the use of the Internet of Things (IoT) in a smart city context primarily stems from civilian applications like management and monitoring, there are also other uses. For instance, military forces may utilize ... -
