Comparison of RADARSAT and IKONOS satellite images - detection and visibility of man-made objects
(2001)This report compares the visual appearance and detection of different man-made objects in an area close to Bergen city in Norway using IKONOS (1 m resolution) and RADARSAT (9 m resolution) images respectively. The results ... -
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 results from some chemical dispersion models and hazard prediction and assessment tools
(2010)Dispersion models and hazard prediction and assessment software tools are used to assess consequences from dispersion of hazardous materials, such as toxic chemicals. Such tools can be employed during and after an event ... -
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 sound propagation codes: Milstøy, BNoise and a PE-method
(2009)Ranges for military training must ensure that noise reaching neighbors is kept at an acceptable level. In Norway, strict noise limits are set by the authorities. To comply with these regulations, the Norwegian Defence ... -
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 thermal runaway initiation methods for a cylindrical Li-ion cell
(2021-08-30)Li-ion batteries have become an important part of our daily life in applications as different as cell phones and electric ferries. High energy density is one of the factors for the successful market penetration of this ... -
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
(2015)Automatic ship reporting systems (AIS – Automatic identification System, LRIT – Long Range Identification and Tracking, VMS – Vessel Monitoring System) today allow global tracking of ships. One way to display the results ... -
Comprehensive quasi-steady force correlations for compressible flow through random particle suspensions
(2023-04-26)Models for quasi-steady drag, quasi-steady drag variation, and transverse forces for compressible flows through random, fixed, particle suspensions are presented. Correlations are formulated using drag force measurements ... -
