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 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 ... -
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 ... -
DSI Suppression with Adaptive Beamforming in DVB-T Passive Radar Measurements
(2018)Adaptive beamforming (ABF) for maximizing the signal to interference plus noise ratio (SINR) is applied to acquisitions made by a passive bistatic radar (PBR) exposed to strong direct signal interference (DSI). The DVB-T ... -
DVB-T Passive Radar Dual Polarization Measurements in the Presence of Strong Direct Signal Interference
(2017)A dual-polarization passive bistatic radar is used to evaluate the potential benefit of cross-polarized measurements for the suppression of strong direct signal interference in the DVB-T band. The linear array antenna ... -
DVL Velocity Aiding in the HUGIN 1000 Integrated Inertial Navigation System
(2004)The RDI WHN-600 Doppler Velocity Log (DVL) is a key navigation sensor for the HUG1N 1000 Autonomous Underwater Vehicle (AUV). HUGIN 1000 is designed for autonomous submerged operation for long periods of time. This is ... -
East or West? : Ukraine's quandary

Echinococcus across the north: Current knowledge, future challenges
(2016)Zoonotic Echinococcus spp. cestodes are present in almost all circumpolar nations, and have historically posed a risk to health of indigenous as well as other northern residents. However, surveillance data on both alveolar ... -
Effect of composite covering on ballistic fracture damage development in ceramic plates
(2017)This paper describes the damage development in ceramics with and without composite cover during ballistic impact. This is relevant for ceramic inserts in body armor that are often covered with a composite material. To study ... -
The effect of contrast in camouflage patterns on detectability by human observers and CAMAELEON
(2015)Evaluation of signature properties of military equipment is very important. It is crucial to apply the proper method out of many possible approaches, based on amongst others ranking by probability of detection, detection ... -
EFFECT OF COULOMB COLLISIONS ON THE GRAVITATIONAL SETTLING OF LOW AND HIGH FIRST IONIZATION POTENTIAL ELEMENTS
(2013)We model the effect of gravitational settling in the upper chromosphere on O, Fe, Si, and Ne, studying whether Coulomb collisions between ionized low First Ionization Potential (FIP) elements and protons is sufficient to ... -
The Effect of Internal Wave-Related Features on Synthetic Aperture Sonar
(2015)In October 2012, the Centre for Maritime Research and Experimentation (CMRE, La Spezia, Italy) conducted trials from the NATO research vessel (RV) Alliance, off Elba Island, Italy. During this trial, data were collected ... -
Effect of the Series Resistance on the Current Response of a HgCdTe Avalanche Photodiode Under High-intensity Nanosecond Irradiation
(2022-05-10)We investigate the nonlinear signal current response of a Hg0.72Cd0.28Te avalanche photodiode (APD) irradiated by high-intensity, finite-duration laser pulses. At high irradiation levels and/or high gains, carrier-induced ... -
Effect of Tonsillar Herniation on Cyclic CSF Flow Studied with Computational Flow Analysis
(2011)BACKGROUND AND PURPOSE: The Chiari I malformation, characterized by tonsils extending below the foramen magnum, has increased CSF velocities compared with those in healthy subjects. Measuring the effect of tonsillar ... -
Effects of 4-methylimidazole on cerebral glutamate decarboxylase activity and specific GABA receptor binding in mice
(2009)4-Methylimidazole (4MeI) is a tremorogenic and convulsive agent of concern both in human and veterinary toxicology. The in vitro effects of 4MeI (5 μM–20 mM) on cerebral glutamate decarboxylase (GAD) activity and (in ... -
Effects of a 7-days military training exercise on inflammatory biomarkers, serum hepcidin, and iron status
(2013)Background Hepcidin, a peptide that is released into the blood in response to inflammation, prevents cellular iron export and results in declines in iron status. Elevated serum and urinary levels of hepcidin have been ... -
The Effects of a UAV on a Terrestrial MANET
(2018)Technological advances on Unmanned Aerial Vehicles (UAVs) and autonomous control could make UAVs useful for communication purposes, extending the range and increasing the performance of Mobile Ad-Hoc Networks (MANETs). However, ...
