Evaluation of Two Path Following Controllers for an Ackermann Off-road Vehicle in Winter and Summer Conditions
(2021-04-02)Off-road driving can be a challenging task with rapid changes in the driving conditions, terrain and vehicle behavior. For off-road autonomous vehicles, it is important to be robust to these changes, and parts of this ... -
Evaluering av Forsvarets logistikksystem – utvikling og anvendelse av et nytt metodisk rammeverk
(2020)Tidligere studier ved Forsvarets forskningsinstitutt har påpekt gap i Forsvarets logistikksystem. Hensikten med denne studien har vært å undersøke om Forsvarets logistikksystem, ved bruk av strategiske partnere, påvirker ... -
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 ... -
Exact 3D scattering solutions for spherical symmetric scatterers
(2018)In this paper, exact solutions to the problem of acoustic scattering by elastic spherical symmetric scatterers are developed. The scatterer may consist of an arbitrary number of fluid and solid layers, and scattering with ... -
Exact Two-Component TDDFT with Simple Two-Electron Picture-Change Corrections: X-ray Absorption Spectra Near L- and M-Edges of Four-Component Quality at Two-Component Cost
(2023-02-01)X-ray absorption spectroscopy (XAS) has gained popularity in recent years as it probes matter with high spatial and elemental sensitivities. However, the theoretical modeling of XAS is a challenging task since XAS spectra ... -
Experimental and numerical study of the fragmentation of expanding warhead casings by using different numerical codes and solution techniques
(2014)There has been increasing interest in numerical simulations of fragmentation of expanding warheads in 3D. Accordingly there is a pressure on developers of leading commercial codes, such as LS-DYNA, AUTODYN and IMPETUS Afea, ... -
Experimental Evaluation of Named Data Networking (NDN) in Tactical Environments
(2020-03-05)Tactical edge networks represent a uniquely challenging environment from the communications perspective, due to their limited bandwidth and high node mobility. Several middleware communication solutions have been proposed ... -
Experimental investigation into radar-based central blood pressure estimation
(2015)To assess whether radar technology can be used for monitoring blood pressure via information from the aorta, two experiments were performed: (i) measurements on a phantom model and (ii) acquisitions on a human subject for ... -
Experimental tomographic scanning (TOSCA) imagers
(2014)The tomographic scanner (TOSCA) detects signals using line detectors scanning a scene at regularly distributed angles. These line scan signals are then processed to reconstruct 2-dimensional images. In the simplest form, ... -
Exploring Network Organization in Military Contexts: Effects of Flatter Structure and More Decentralized Processes
(2011)Changes in the tasks and responsibilities of military organizations in recent decades have prompted new organizational solutions collectively known as network organization. Network organization includes changes to central ... -
Exploring the overlapping binding sites of ifenprodil and EVT‐101 in GluN2B‐containing NMDA receptors using novel chicken embryo forebrain cultures and molecular modeling
(2019-05-30)N‐methyl‐d‐aspartate receptors (NMDAR) are widely expressed in the brain. GluN2B subunit‐containing NMDARs has recently attracted significant attention as potential pharmacological targets, with emphasis on the functional ... -
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, ... -
