Deep temporal detection - A machine learning approach to multiple-dwell target detection
(2020)
Detecting small targets, such as an Unmanned Aerial Vehicle (UAV) in high clutter and non-homogeneous environments is challenging for a radar system. Traditional Constant False Alarm Rate (CFAR) detectors have suboptimal ...
Path Planning for UGVs Based on Traversability Hybrid A*
(2021-02-01)
In this letter, a new method of path planning for unmanned ground vehicles (UGVs) on terrain is developed. For UGVs moving on terrain, path traversability and collision avoidance are important factors. If traversability ...
Changes in inoperability for interdependent industry sectors in Norway from 2012 to 2017
(2021-03)
The purpose of this work has been to investigate changes in interdependencies between Norway's mainland industry sectors and how it might affect national security. To this end, the interdependencies were analysed by using ...
Sparse range-Doppler image construction with neural networks
(2020-06-11)
The principles outlined by compressed sensing can
permit a sensor to collect reduced amount of data and still
reconstruct an exact outcome. This can for example be used
to generate super-resolution sparse range-Doppler ...
A framework for automatic behavior generation in multi-function swarms
(2020)
Multi-function swarms are swarms that solve multiple tasks at once. For example, a quadcopter swarm could be tasked with exploring an area of interest while simultaneously functioning as ad-hoc relays. With this type of ...
Laminar burning velocity of the dimethyl carbonate–air mixture formed by the Li-ion electrolyte solvent
(2020-08-21)
If a Li-ion cell fails and the electrolyte leaks out into air, a flammable premixed gas cloud can be formed. The electrolyte combustion energy is 65–70% of the total energy content of the cell. The main objective of this ...
Redrawing borders, reshaping orders: Russia’s quest for dominance in the Black Sea region
(2021-01-04)
Since Russia’s annexation of Crimea in March 2014, severe limitations have been placed on Ukraine’s coastal state rights and navigational freedoms in the Black and Azov Seas and the Kerch Strait. The "Kerch Strait clash" ...
Generative Adversarial Immitation Learning for Steering an Unmanned Surface Vehicle
(2020-02)
The task of obstacle avoidance using maritime vessels, such as Unmanned Surface Vehicles (USV), has traditionally been solved using specialized modules that are designed and optimized separately. However, this approach ...
Specifying radiometric performance of hyperspectral and conventional cameras: A minimal set of independent characteristics
(2020)
The radiometric performance of cameras is customarily characterized and specified in terms of component properties such as F-number and readout noise. This paper considers the camera as an integrated unit and derives ...
Modeling and Simulation as a Service infrastructure capabilities for discovery, composition and execution of simulation services
(2020-01-13)
Modeling and Simulation as a Service (MSaaS) embodies the idea that simulations should be composed quickly for the task at hand from loosely coupled shared components, simulation services, in a cloud-based environment. ...
