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 ... -
Detection of military objects in LADAR images
(2008)This report describes different techniques for preprocessing, segmentation, and detection of vehicle sized objects in LADAR images. Five preprocessing strategies are presented; 1) Median filtering, 2) Two 1-D median ... -
Detection of Point Scatterers in Medical Ultrasound
(2021-11-19)We present an overview of the detection of point scatterers in ultrasound images and suggest strategies for evaluating and measuring the detection performance. We use synthetic aperture Field II simulations of a point ... -
Detection performance for Incoherent Range Walk Compensation
(2014-11-24)FFI supports the Royal Norwegian Air Force in their acquisition of new air surveillance sensors. Improved detection performance on low observable targets may be obtained by increasing the radar dwell time on target. For ... -
Detection: how many pixels are required?
(2020-09-23)In this work, we studied how detection range of a small target changes as a function of the number of defined target pixels. The intuitively simplest method to look for a target in IR images is to look for the “hottest” ... -
Deteksjon av eksplosivrester i felt ved hjelp av hyperspektral avbildning
(2009)Der er kjent at det i Forsvarets skytefelt ligger rester av eksplosiver, noe som hovedsakelig skyldes ufullstendig detonasjon av ammunisjon. Disse restene er vanskelige å finne, men er ansett å være et miljøproblem blant ... -
Determination of chemical warfare agents in water samples by solid phase microextraction and GC-FID
(2007)The Norwegian Defence Research Establishment (FFI) is presently developing a mobile laboratory for the identification of chemical warfare agents (CWA) and related compounds. The laboratory will be used in the field, and ... -
Determination of critical diameter for DPX-6
(2006)M72 LAW (Light Antiarmour Weapon) has been redesigned with a new warhead for urban warfare. The new warhead is designed for combat of light buildings and therefore needs an explosive filling that is optimized for this ... -
Determination of detonation pressure and velocity for RDX/GAP propellant
(2017-03-13)Detonation velocity and detonation pressure have been determined for the solid propellant D- 07, a RDX/GAP propellant produced by Nammo Raufoss. Three firings, two with test item diameter 35.6+1 mm and one with diameter ... -
Determination of detonation velocity and plate dent properties fir DPX-6
(2006)M72 LAW (Light Antiarmour Weapon) has been redesigned with a new warhead for urban warfare. The new warhead is designed for combat of light buildings and therefore need an explosive filling that is optimized for this ... -
Determination of detonation velocity and plate dent properties of DPX-5
(2008)Detonation velocity for DPX-5 Ch 01/07 has been determined both experimentally and theoretically by use of the Cheetah 2.0 code. The measured detonation velocity was found to be 8276 m/s or approximately 350 m/s higher ... -
Determination of detonation velocity and Plate Dent properties of DPX-9 and DPX-10
(2009)Two press and formable new plastic explosive compositions developed by Chemring Nobel containing RDX as main filler have been studied. Pellets pressed by Chemring Nobel AS were glued together at FFI to test charges of ... -
Determination of detonation velocity and plate dent properties of PBXV-11 with 30 WT.% aluminium
(2008)Studied composition PBXW-11with 30wt.% aluminium class 7 powder is a Norwegian produced explosive equal to the American PBXIH-18 composition. By slightly modification of the aluminium content the studied composition will ... -
Determination of detonation velocity and pressure for MCX-6100
(2015-12-02)Independent of the application of an explosive composition there are certain properties that are important to know. Performance depends on properties as detonation velocity and detonation pressure. Sensitivity of munitions ... -
Detonation transfer : summary report, FFI project 803.03
(2003)In connection with the upgrade of AMRISK, a program for risk analysis of ammunition storages, the process of detonation transfer have been studied. Based on earlier work a model for sympathetic detonation is developed ... -
DETOUR trials: The mission and its results
(2017)In this paper DMPAR Evaluation Trials for Operationally Upgraded Radar (DETOUR) and their results for a selected scenario are described. The DETOUR trials were conducted by the SET-195 research task group (RTG) under an ... -
Development and Calibration of a Low-Cost Radar Testbed Based on the Universal Software Radio Peripheral
(2019-12-01)For a cognitive radar algorithm to be useful, it must run on radar hardware that is flexible. Typically, this has been viewed as requiring a software-defined radio. With the emergence of cheap, digital transceiver systems, ... -
Development of a chemical, atomic and toxic compound surveillance system - CATSS
(2004)A demonstrator of an automatic surveillance system for chemical, radiological and toxic compounds, called CATSS, has been developed at FFI. The system contains several commercially available detectors integrated into CATSS. ... -
Development of LES inflow conditions for turbulent boundary layers
(2013-10-31)Computational Fluid Dynamics (CFD) is currently the only known physically based method to model dispersion and transport of aerosols and gases in complex urban environments. One of the main challenges with CFD simulations ...
