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 ...
