Explosion characteristics for Li-ion battery electrolytes at elevated temperatures
(2019-01-28)Li-ion batteries are used in electronic devices and electric cars, yet they create safety concerns due to the possibility of the release of combustible materials. The electrolyte, one of the main components in a Li-ion ... -
Extraction and classification of vehicles in LADAR imagery
(2013)The work presented in this paper is based on a dataset recorded with an airborne sensor. It comprises targets like M-60, M-47, M-113, bridge layers, tank retrievers, and trucks in various types of scenes. The background-object ... -
Eye-safe fiber laser for long range 3D imaging applications
(2018)We report an all-fiber Er/Yb master oscillator power amplifier at 1.55 μm, delivering 135 μJ pulses with 6 ns duration (full width at half-maximum) at 100 kHz pulse repetition frequency, limited by stimulated Brillouin ... -
Fast and robust image processing algorithms based on approximations to order statistics
(2018)A test system with four cameras in the infrared and visual spectra is under development at FFI (The Norwegian Defence Research Establishment). The system can be mounted on a high speed jet aircraft, but may also be used ... -
Feasibility of a standard for full specification of spectral imager performance
(2017)The current state of the art of specifying spectral imagers falls short of what is needed. Commercial datasheets do not adequately reflect the performance of hyperspectral imagers offered as standard products. In particular, ... -
Federated Identity Management in a Tactical Multi-Domain Network
(2011)Identity Management maintains information regarding actors of an Information System, like users, equipment and services. One important service is to disseminate and validate credentials for the purpose of authentication ... -
Federated single sign on in disconnected, intermittent and limited (DIL) networks
(2015)In a military setting resource exchange amongst coalition partners is of great importance. Using SAML2.0 in a Single Sign On scheme in a federated setting can be a solution to Web authentication of Web resources. The problem ... -
Federating Tactical Edge Networks:Ways to Improve Connectivity, Security, and Network Efficiency in Tactical Heterogeneous Networks
(2020-02-14)This article elaborates on security and routing architectures for mobile tactical heterogeneous networks. It explores challenges and opportunities, and highlights the characteristics of these types of networks and their ... -
The FESTER field trial
(2016)An overview is given of the First European – South African Transmission ExpeRiment (FESTER), which took place in South Africa, over the False Bay area, centered around Simon’s Town. The experiment lasted from April 2015 ... -
FESTER: a propagation experiment, overview and first results
(2016)A long term field trial called FESTER (First European South African Transmission Experiment) has been conducted by an international collaboration of research organizations during the course of almost one year at False Bay, ... -
Few-cycle pulse generation by double-stage hybrid multi-pass multi-plate nonlinear pulse compression
(2023-02-10)Few-cycle pulses present an essential tool to track ultrafast dynamics in matter and drive strong field effects. To address photon-hungry applications, high average power lasers are used which, however, cannot directly ... -
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, ... -
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. ... -
Fighting on behalf of the state—the issue of pro-government militia autonomy in the Donbas war
(2019-01-04)This study investigates the degree of autonomy the Ukrainian volunteer battalions had from the regular forces during the war in Donbas. The findings indicate that the degree of autonomy was high and that in particular, ... -
The final destination: building test bed apps for DIL environments
(2015)Recent years have seen a massive growth in the everyday use of smartphones and tablet (here called smart mobile devices or SMDs) and a turn towards app based software to connect to cloud based services. This has had a huge ... -
The First GAEN-Based COVID-19 Contact Tracing App in Norway Identifies 80% of Close Contacts in “Real Life” Scenarios
(2021-11-17)The coronavirus disease 2019 (COVID-19) response in most countries has relied on testing, isolation, contact tracing, and quarantine (TITQ), which is labor- and time-consuming. Therefore, several countries worldwide launched ... -
First in situ measurement of the vertical distribution of ice volume in a mesospheric ice cloud during the ECOMA/MASS rocket-campaign
(2009)We present in situ observations of mesospheric ice particles with a new particle detector which combines a classical Faraday cup with the active photoionization of particles and subsequent detection of photoelectrons. Our ... -
First indications that northern bottlenose whales are sensitive to behavioural disturbance from anthropogenic noise
(2015)Although northern bottlenose whales were the most heavily hunted beaked whale, we have little information about this species in its remote habitat of the North Atlantic Ocean. Underwater anthropogenic noise and disruption ... -
Flow noise reduction from superhydrophobic surfaces
(2012)This work investigates how a highly (super)hydrophobic surface can be used to reduce turbulence-generated drag and noise on a towed streamer cable. The work is done by analyzing full-scale drag and flow noise measurements ...
