Testing of two M7 propellant lots in closed vessel
(2009)Two different lots of M7 propellant for use in M72 rockets have been tested at room temperature in closed vessel to investigate if they have different burning properties. The studied lots were lot NARA 128 and lot NARA ... -
Testing og karakterisering av PBXN-110
(2007)To partier av HMX krystaller med krystallfordeling tilsvarende klasse 2 og 3 har vært benyttet til fremstilling av PBXN-110 med 87.2 vektprosent HMX. Hensikten med fremstilling av PBXN-110 var å studere om benyttede ... -
Testoppsett for sikkerhetsmekanismer i VoIP
(2014-08-13)Denne rapporten utforsker muligheten for sikring av Voice-over-IP (VoIP)-trafikk, og demonstrerer hvordan man kan sette opp server og klienter for eksperimentering med VoIPsikkerhet. Dette innebærer bruk av ulike ... -
Tests of Hesco gabions June 2011
(2012-03-06)English summary In June 2011 a number of tests of the protective properties of Hesco gabions relative to various weapon threats were accomplished. The experiments are part of a series of tests involving physical force ... -
Tests of the Missionland dataset
(2013-02-11)The objective of the NATO Science and Technology Organization Task Group MSG-071 “Missionland” is to construct a dataset from which simulation environment databases can be created. FFI is planning to use the dataset. As a ... -
Tetanus: Pathophysiology, Treatment, and the Possibility of Using Botulinum Toxin against Tetanus-Induced Rigidity and Spasms
(2013)Tetanus toxin, the product of Clostridium tetani, is the cause of tetanus symptoms. Tetanus toxin is taken up into terminals of lower motor neurons and transported axonally to the spinal cord and/or brainstem. Here the ... -
The ECOMA 2007 campaign: rocket observations and numerical modelling of aerosol particle charging and plasma depletion in a PMSE/NLC layer
(2009)The ECOMA series of rocket payloads use a set of aerosol particle, plasma, and optical instruments to study the properties of aerosol particles and their interaction with the ambient plasma environment in the polar mesopause ... -
Theoretical and experimental investigation of strain gradients for transversal shear stress determination in GRP sandwich panels
(2001)This report describes a theoretical and experimental investigation for transversal shear stress determination in the core of a sandwich panel. The outlined method is based on strain gradient measurements on the surface ... -
A theoretical study of small scale turbulence in stratified turbulent shear flows
(2004)This report examines the postulate of local isotropy in stratified homogeneous turbulence from a theoretical point of view. The study is based on a priori analysis of the evolution equations governing single-point turbulence ... -
Thermal and mechanical analyses for the NSAT-1 phase B study
(2003)The Norwegian Defence Research Establishment (FFI) and industry partners are looking into a possible development of a micro satellite system (NSAT-1) with an X-band vessel-detector antenna to geolocation vessels for ... -
Thermal effects in end-pumped solid state lasers - influence on resonator stability, beam quality, and output power
(2001)A theoretical analysis is given of the magnitudes of thermal effects in end-pumped high-power solid state lasers, and their influence on the laser output characteristics, particularly the beam quality and conversion ... -
Thermal infrared reference sources fabricated from low-cost components and materials
(2018)Mass markets, including mobile phones and automotive sensors, drive rapid developments of imaging technologies toward high performance, low cost sensors, even for the thermal infrared. Good infrared calibration blackbody ... -
Thermal sensor acquisition range estimation
(2021-06-24)There is a large number of factors which may influence the performance of thermal surveillance systems used in any given scenario. Some of the parameters needed for making an accurate performance prediction might be ... -
Thermal stability of NMC442 cathode material studied by accelerating rate calorimetry
(2020-12-07)Lithium ion batteries have developed into one of the most popular secondary batteries on the market today due to high voltage, long lifetime and high energy density. However, lithium ion batteries may have safety issues, ... -
Third-generation femtosecond technology
(2014)Femtosecond pulse generation was pioneered four decades ago using mode-locked dye lasers, which dominated the field for the following 20 years. Dye lasers were then replaced with titanium-doped sapphire (Ti:Sa) lasers, ... -
Thirty years after its foundation – where is al-Qaida going?
(2017)This article presents a framework for understanding al-Qaida, based on a new reading of its thirty-year history. Al-Qaida today is commonly labelled a ‘global insurgency’ or ‘global franchise.’ However, these labels are ... -
The threat of war and domestic restraints to defence reform- how fear of major military conflict changed and did not change the Ukrainian military 2014-2019
(2019-12-19)The annexation of Crimea and the Russia enabled rebellion in Donbas created a need for radical improvements of Ukrainian military capability. This study discusses how different, mostly domestic, reform drivers and reform ... -
