Characterization of a compact 6-band multifunctional camera based on patterned spectral filters in the focal plane
(2014)In some applications of multi- or hyperspectral imaging, it is important to have a compact sensor. The most compact spectral imaging sensors are based on spectral filtering in the focal plane. For hyperspectral imaging, ... -
Active spacecraft potential control investigation
(2014)In tenuous plasma the floating potential of sunlit spacecraft reaches tens of volts, positive. The corresponding field disturbs measurements of the ambient plasma by electron and ion sensors and can reduce micro-channel ... -
Real-time anomaly detection in hyperspectral images using multivariate normal mixture models and GPU processing
(2009)Hyperspectral imaging, which records a detailed spectrum of light arriving in each pixel, has many potential uses in remote sensing as well as other application areas. Practical applications will typically require real-time ... -
Extraction and classification of vehicles in LADAR imagery
(2013)The work presented in this paper is based on a dataset recorded with an airborne sensor. It comprises targets like M-60, M-47, M-113, bridge layers, tank retrievers, and trucks in various types of scenes. The background-object ... -
Anisotropic scattered data interpolation for pushbroom image rectification
(2014)This paper deals with fast and accurate visualization of pushbroom image data from airborne and spaceborne platforms. A pushbroom sensor acquires images in a line-scanning fashion, and this results in scattered input data ... -
Real-time PCR and NASBA for rapid and sensitive detection of Vibrio cholerae in ballast water
(2012)Transport of ballast water is one major factor in the transmission of aquatic organisms, including pathogenic bacteria. The IMO-guidelines of the Convention for the Control and Management of Ships’ Ballast Water and ... -
Detection of Legionella pneumophila in a biological treatment plant by co-cultivatiobn with Acanthamoeba castellanii
(2014)Legionella pneumophila was identified in the aeration ponds of a biological wastewater treatment plant at the pulp and paper industry Borregaard, Sarpsborg, Norway. After 3 outbreaks of Legionaires’ disease reported in ... -
Integrated Camera-Based Navigation
(2000)This paper presents an integrated INS (Inertial Navigation System) and camera-based navigation system. The camera-based navigation system provides position measurement aiding to the INS. This is an alternative to the more ... -
Is it Possible to Increase the Share of Military Women in the Norwegian Armed Forces?
(2014)Ever since Norway introduced general conscription for men in 1897, the participation of women in the Norwegian Armed Forces (NorAF) has been an issue for discussion. In 1984 the NorAF introduced occupational equality ... -
Phase-coherent communications without explicit phase tracking
(2010)Phase-coherent communications typically requires a reliable phase-tracking algorithm. An initial phase estimate with training symbols allows a receiver to compensate for a motion-induced Doppler shift. Following the training ... -
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 ... -
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 ... -
Sensor noise informed representation of hyperspectral data, with benefits for image storage and processing
(2011)Many types of hyperspectral image processing can benefit from knowledge of noise levels in the data, which can be derived from sensor physics. Surprisingly, such information is rarely provided or exploited. Usually, the ... -
The red-sky enigma over Svalbard in December 2002
(2005)On 6 December 2002, during winter darkness, an extraordinary event occurred in the sky, as viewed from Longyearbyen (78° N, 15° E), Svalbard, Norway. At 07:30 UT the southeast sky was surprisingly lit up in a deep red ... -
Results of a Ka Band Campaign for the Characterisation of Propagation Conditions for SatCom Systems at High Latitudes
(2017)Satellite services in the High North are utilized extensively for both communication purposes and for earth and climate observations. This paper presents results of two year measurements at 20 GHz and co-sited meteorological ... -
Robust Web Services in Heterogeneous Military Networks
(2010)NATO Network Enabled Capability is firstand foremost about achieving better interactionbetween the different actors involved in militaryoperations. This implies more efficient exchangeof information. Consequently, the NATO ... -
Using web services to realize service oriented architecture in military communication networks
(2007)The principles of network enabled capability highlight the need for seamless information exchange. The service oriented architectural paradigm has been recognized as one of the key enablers to achieve this. At the same ... -
