Multi-channel and multi-polarisation ship detection
(2012)
Norway's large ocean areas in the North require efficient methods to detect vessels in the High North. Radar satellites in orbit today offer dual- or quad-polarised data, which ease the task of detecting vessels in a SAR ...
The Rise of Muslim Foreign Fighters Islam and the Globalization of Jihad
(2010)
Why has transnational war volunteering increased so dramatically in the Muslim world since 1980? Standard explanations, which emphasize U.S.-Saudi support for the 1980s Afghan mujahideen, the growth of Islamism, or the ...
Detection of forest clear-cuts with shuttle radar topography mission (SRTM) and tandem-X InSAR data
(2013)
The aim of this study was to determine whether forest clear-cuts during 2000–2011
could be detected as a decrease in surface height by combining Digital Surface Models
(DSMs) from the Shuttle Radar Topography Mission ...
Terahertz imaging of composite materials in reflection and transmission mode with a time-domain spectroscopy system
(2016)
A fiber-coupled Terahertz time domain spectroscopy (THz-TDS) system based on photoconductive antennas, pumped by a 100-fs fiber laser, has been used to characterize materials in transmission and reflection mode. THz images ...
Quantifying the tracking capability of space-based AIS systems
(2016)
The Norwegian Defence Research Establishment (FFI) has operated three Automatic Identification System (AIS) receivers in space. Two are on dedicated nano-satellites, AISSat-1 and AISSat-2. The third, the NORAIS Receiver, ...
Minimum Variance Signal Selection for Aorta Radius Estimation Using Radar
(2010)
This paper studies the optimum signal choice for the estimation of the aortic blood pressure via aorta radius, using a monostatic radar configuration. The method involves developing the Cramér-Rao lower bound (CRLB) for a ...
A concept approach to input/output logic
(2015)
This paper provides a semantics for input/input output logic based on formal concept analysis. The central result shows that an input/output logic axiomatised by a relation R is the same as the logic induced by deriving ...
Severe gunshot injuries in a porcine model: impact on central markers of innate immunity
(2011)
Background
The mechanisms behind lipopolysaccharide (LPS) tolerance remain obscure. LPS signals through Toll-like receptor 4 (TLR4) and severe trauma/haemorrhage may influence binding and signalling through this receptor, ...
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 ...
Mathematical simulation of enegy expenditure and recovery during sprint cross-country skiing
(2014)
Purpose: A cross-country sprint competition relies on maximal effort durations of 3–4 minutes. Significant anaerobic energy contribution is expected. Anaerobic energy contribution has been estimated in different sports to ...
