Discrete Fourier Transform with Neural Networks
(2021-12-10)The discrete Fourier transform is an important computational tool to retrieve the frequency distribution of a sampled signal. Recent years have also witnessed considerable research activity in neural networks as a mean to ... -
Discriminating between camouflaged targets by their time of detection by ahuman based observer assessment method
(2015)Detection of a camouflaged object in natural sceneries requires the target to be distinguishable from its local background. The development of any new camouflage pattern therefore has to rely on a well-founded test methodology ... -
Dispersion of SARS-CoV-2 in air surrounding COVID-19-infected individuals with mild symptoms
(2022-02-12)Since the beginning of the pandemic, the transmission modes of SARS-CoV-2—particularly the role of aerosol transmission—have been much debated. Accumulating evidence suggests that SARS-CoV-2 can be transmitted by aerosols, ... -
Disruptive camouflage tricks the human eye - a study of detection times of two near-similar targets in natural backgrounds
(2015)Our understanding of camouflage, in military as well as in evolutionary perspectives, has been developing over the last 100 years. In that period of time several underlying principles have emerged. It has turned out in the ... -
Disruptive coloration in woodland camouflage: evaluation of camouflage effectiveness due to minor disruptive patches
(2016)We present results from an observer based photosimulation study of generic camouflage patterns, intended for military uniforms, where three near-identical patterns have been compared. All the patterns were prepared with ... -
Distributed certificate validation in MANET
(2009)The need for certificate management in mobile ad hoc networks (MANET) is the background for this report. A prototype implementation of a distributed certificate validation service is presented and evaluated. The proposed ... -
Distributed fusion in underwater sensor networks: Fusing bearing information
(2019)In underwater sensor networks, distributed data fusion may be more efficient than centralized fusion because the limited data transmission capacity can make it difficult to collect all required sensor information at a ... -
Distribution and mobility of lead (Pb), antimony (Sb) and copper (Cu) from ammunition residues on shooting ranges for small arms located on mires
(2017)An environmental survey was performed on shooting ranges for small arms located on minerotrophic mires. The highest mean concentrations of Pb (13 g/kg), Cu (5.2 g/kg), Zn (1.1 g/kg), and Sb (0.83 g/kg) in the top soil were ... -
Disturbance-specific social responses in long-finned pilot whales, Globicephala melas
(2016)Social interactions among animals can influence their response to disturbance. We investigated responses of long-finned pilot whales to killer whale sound playbacks and two anthropogenic sources of disturbance: tagging ... -
Dokumentasjon av Commander´s quest : en systemdynamisk modell til støtte for minimalistisk beslutningstrening
(2003)This report describes Commander’s Quest; the second of a total of five system dynamic models in the FFI-project 846 – Implementering av beslutningstrener (BST II). Commander’s Quest is a gaming model for running ... -
Dokumentasjon av Executive Force : en systemdynamisk modell til støtte for minimalistisk beslutningstrening
(2003)This report describes Executive Force; the third of a total of five system dynamic models in the FFI-project 846 – Implementering av beslutningstrener (BST II). The model presents a holistic view on the forces governing a ... -
Dokumentasjon av Iwo Jima en systemdynamisk modell til støtte for minimalistisk beslutningstrening
(2003)This report describes Iwo Jima; the first of a total of five system dynamic models in the FFI-project 846 – Implementering av beslutningstrener (BST II). Iwo Jima models a conflict between to countries; Redland and ... -
Dokumentasjon av Vectura : en systemdynamisk modell til støtte for minimalistisk beslutningstrening
(2003)This report describes Vectura; the fourth of a total of five system dynamic models in the FFI-project 846 - Implementering av beslutningstrener (BST II). Vectura is a logistics model containing: Transport, deployment, ... -
Dokumentasjon om al-Qaida - intervjuer, kommunikéer og andre primærkilder, 1990-2002
(2003)This report is an attempt at gathering all available statements and interviews given to foreign media by Usama bin Ladin and his al-Qa‘ida organization from the early 1990s through 2002. The bulk of this material has been ... -
Dose response severity functions for acoustic disturbance in cetaceans using recurrent event survival analysis
(2015)Behavioral response studies (BRSs) aim to enhance our understanding of the behavior changes made by animals in response to specific exposure levels of different stimuli, often presented in an increasing dosage. Here, we ... -
Dose-response relationships for the onset of avoidance of sonar by free-ranging killer whales
(2014)Eight experimentally controlled exposures to 1−2 kHz or 6−7 kHz sonar signals were conducted with four killer whale groups. The source level and proximity of the source were increased during each exposure in order to reveal ... -
Driftskostnadsvekst estimert med Bayesianske metoder
(2005)This report gives a Bayesian analysis of operating cost escalation in the Norwegian Armed Forces. The amount of relevant data is limited to nine data points from the time period 1994-2002. We present a statistical model ...
