Telemetrienkoder til bruk i vitenskapelige sonderaketter - dokumentasjon og bruksanvisning
(2009)I perioden 2005 til 2007 ble det designet og produsert en ny telemetrienkoder på FFI til bruk i vitenskapelige sonderaketter. Denne rapporten er skrevet som en bruksanvisning og brukerveiledning til telemetrienkoderen ... -
TEMPER simulations for 120 mm IM HE-T
(2015-11-17)Three of the IM threats, bullet impact, fragment impact and sympathetic reaction, have been studied by simulations with the MSIAC software TEMPER. TEMPER has been used to calculate the IM responses of 120 mm IM HE-T ... -
TEMPER simulations of bullet impact and fragment impact tests of 155 mm shell filled with MCX-6100 composition
(2015-10-22)IM classification of munitions requires testing according to STANAG 4439 (1). All tests have to be performed unless the Threat Hazard Analysis shows that specific threats in the STANAG do not exist for the life cycle of ... -
TEMPER simulations of MCX-6100 filled 155 mm shell - experimental properties, sympathetic reaction and fragmentation studies
(2015-10-22)IM classification of munitions requires testing according to STANAG 4439 (1). The exception is if the Threat Hazard Analysis shows that a specific threat in the STANAG does not exist for the life cycle of the munitions. ... -
Temperature dependent lattice constant of Al0.90Ga0.10AsySb1-y
(2010)Using x-ray diffraction, the in-plane and out-of-plane lattice constants of Al0.90Ga0.10AsySb1−y epilayers grown on GaSb and GaAs substrates were determined between 30 and 398 °C for y = 0.003–0.059. The bulk lattice ... -
Temperaturmålinger av loddeprofil for EKKO II kretskort
(2010)I forbindelse med produksjon av et EKKO II kretskort i OPEK prosjektet ved FFI, ble det oppdaget at RAM brikkene ikke lenger fungerte etter lodding i dampfaseovnen. EKKO II kretskortet består av både blyholdige og blyfri ... -
Temporal dynamics in microbial soil communities at anthrax carcass sites
(2017)Background Anthrax is a globally distributed disease affecting primarily herbivorous mammals. It is caused by the soil-dwelling and spore-forming bacterium Bacillus anthracis. The dormant B. anthracis spores become ... -
Temporal stability of X-band single-pass InSAR heights in a spruce forest: Effects of acquisition properties and season
(2015)We investigated the stability of TanDEM-X interferometric synthetic aperture radar (InSAR) heights across eight repeated acquisitions. With InSAR height we mean the height above ground of the scattering phase center. We ... -
Temporal variability of the bioaerosol background at a subway station: Concentration level, size distribution, and diversity of airborne bacteria
(2014)Naturally occurring bioaerosol environments may present a challenge to biological detection-identification-monitoring (BIODIM) systems aiming at rapid and reliable warning of bioterrorism incidents. One way to improve the ... -
Tenders in European Defence Procurement : selective TED Publication Survey 2015
(2016-11-04)The European market in defence and security equipment and services is customarily perceived as rather fragmented and closed in the sense that relatively few contracts are awarded across borders. After the transposition ... -
Tensile tests of Wolfram Carbide hard cores
(2007)In this report an experimental study of the tensile strength of different hard cores of Wolfram Carbide was performed. A bending test was constructed for the study. We show that the tensile strength and strain is smaller ... -
Tensor analysis applied to the equations of contiuum mechanics I
(2014-01-27)The Navier-Stokes equations, the Euler equations, the equations of elasticity and expressions derived from those, are in most cases treated in Cartesian coordinates. In some cases it can necessary to handle those equations ... -
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 ... -
Termisk signatur fra objekt og bakgrunn - sluttrapport for prosjekt 775
(2002)In project 775, models for simulation of thermal signature for natural backgrounds and for vehicles have been developed. Both models were calibrated and evaluated on the basis of meteorological data and real thermal images. ... -
Termogravimetrisk og dynamisk mekanisk analyse av polymermatriser
(2004)In this work improved DMA and TGA methods were developed in order to measure glass transition temperatures and study thermochemical properties of various polymer matrices suited for binders in rocket propellants. Several ... -
Terne - et anti ubåtvåpen
(Forsvarets forskningsinstitutt, 2003)I 1946 nedsatte forsvarsminister Jens Chr. Hauge ”Forsvarskommisjonen av 1946” med oppdrag bl.a. å vurdere det teknologiske perspektiv i forsvarssammenheng. FFI bidro ves-entlig til kommisjonens arbeid gjennom sine ”Tekniske ... -
Terrain referenced navigation using sand dunes and sand ripples in presence of tides
(2018)We investigated using terrain referenced navigation in shallow water in the presence of unknown tide, with an autonomous underwater vehicle equipped with a high resolution bathymetric sensor. The mission area had both ... -
Terrengets påvirkning av jordbølgen på HF : måleresultater og analyse
(2004)The two categories of HF operations are sky waves and ground waves. The focus in this report has been on ground wave, which consists of the direct wave, reflected wave and surface wave. The International Telecommunication ... -
Terrengreferert posisjonering for undervannsfarkoster
(2001)This report deals with terrain referenced positioning of underwater vehicles, also known as terrain correlation. There is no fundamental difference from airborne platforms. The report treats search methods and gradient ...
