Communities of Trust in Tactical Coalition Networks
(2014)The need for information exchange between security domains has traditionally been approached through the use of guards and security labels. Although these technologies are thoroughly researched and exist in mature ... -
Compact airborne C-band radar sounder
(2014)We describe a lightweight wideband C-band radar sounder, which is designed for use in a small unmanned aerial vehicle, primarily for measuring snow and ice. The waveform used is a gated frequency modulated continuous wave, ... -
Compact camera for multispectral and conventional imaging based on patterned filters
(2014)A multispectral camera concept is presented. The concept is based on using a patterned filter in the focal plane, combined with scanning of the field of view. The filter layout has stripes of different bandpass filters ... -
Compact multimodal multispectral sensor system for tactical reconnaissance
(Society of Photo-Optical Instrumentation Engineers (SPIE), 2022-09-30)Multispectral imaging is an attractive sensing modality for small unmanned aerial vehicles (UAVs) in numerous military and civilian applications such as reconnaissance, target detection, and precision agriculture. Cameras ... -
Compact multispectral multi-camera imaging system for small UAVs
(2016)Cameras with filters in the focal plane provide the most compact solution for multispectral imaging. A small UAV can carry multiple such cameras, providing large area coverage rate at high spatial resolution. We investigate ... -
Comparative testing and evaluation of nine different air samplers: End-to-end sampling efficiencies as specific performance measurements for bioaerosol applications
(2014)Accurate exposure assessments are needed to evaluate health hazards caused by airborne microorganisms and require air samplers that efficiently capture representative samples. This highlights the need for samplers with ... -
Comparative visualization of multiple time surfaces by planar surface reformation
(2016)Comparing time surfaces at different integration time points, or from different seeding areas, can provide valuable insight into transport phenomena of fluid flows. Such a comparative study is challenging due to the often ... -
Comparing RLS and LMS adaptive equalizers for large hydrophone arrays in underwater acoustic communication channels
(2019-10-14)There is an expected growth in underwater acoustic data traffic. To meet the demand of high data throughput, a migration towards the very high frequency band (>100 kHz) will be necessary. The increment in frequency comes ... -
Comparing VO2max Improvement in Five Training Methods
(2012)This paper presents a theoretical study comparing the improvement of the whole body maximum oxygen uptake (maximum aerobic power or VO2max) when training at different intensities and with different methods matched for ... -
Comparison of Measurements with Prediction Methods for Propagation by diffraction at88 - 108 MHz
(2004)Three methods for predicting attenuation due to diffraction are tested against a large database of 115 614 measurement points, representing 115 614 different path profiles of 100-m horizontal resolution, and vertical root ... -
A comparison of rain attenuation and drop size distributionsmeasured in Chilbolton and Singapore
(2002)Attenuation of radio waves caused by precipitation, especially in the form of rain, is considered to be the limiting factor for new communication systems that will exploit the radio wave spectrum at frequencies higher than ... -
Comparison of simulated and measured ISAR images flow of a ship at sea
(2021-07-02)The aim of this work is to simulate a flow of ISAR images for a ship at sea seen from an airborne radar, in rigorously the same configuration as it has been measured by a real SAR using the recorded motion data of both ... -
Comparison of synthetic aperture sonar images and optical images of UXOs from the Skagerrak chemical munitions dumpsite
(2019-11-28)After World War II chemical munitions were loaded onto large ships and sunk in the Skagerrak Strait in the Norwegian trench, in deep waters between Norway and Denmark. In collaboration with the Norwegian Coastal Administration, ... -
Comparison of terahertz technologies for detection and identification of explosives
(2014)We present results on the comparison of different THz technologies for the detection and identification of a variety of explosives from our laboratory tests that were carried out in the framework of NATO SET-193 “THz ... -
Comparison of two methods for automatic range alignment in ISAR imaging
(2011)A maximum likelihood algorithm for translational motion estimation (TME) in ISAR imaging is described and compared with prominent point processing (PPP). It is suggested that the kurtosis (fourth order central moment) of ... -
Complete genome sequences of six Legionella pneumophila isolates from two collocated outbreaks of legionnaires' disease in 2005 and 2008 in Sarpsborg/Fredrikstad, Norway
(2016)Here, we report the complete genome sequences of Legionella pneumophila isolates from two collocated outbreaks of Legionnaires’ disease in 2005 and 2008 in Sarpsborg/Fredrikstad, Norway. One clinical and two environmental ... -
Completeness and Accuracy of a Wide-Area Maritime Situational Picture based on Automatic Ship Reporting Systems
