Penetration into concrete by truncated projectiles
(2000)In this report we examine the penetration into semi–infinite concrete targets by truncated projectiles. Forrestal’s semi–analytical penetration formula for ogive–nosed projectiles has earlier been seen to give good ... -
Penetration into modular targets
(2002)Penetration into modular targets (i.e. a wall or similar structure consisting of several target blocks) is examined using a variety of methods. Full Autodyn-3D simulations are performed and supported by analytical calculations. ... -
Penetration into rock-rubble overlays
(2024-01-15)Rock-rubble overlays can be used for protection against projectiles. Due to the asymmetric and stochastic properties of a rock-rubble overlay, incoming projectiles can be deflected or may even ricochet. In this report we ... -
Penguin – en målsøkende rakett mot skip
(Forsvarets forskningsinstitutt, 2006)Penguin-prosjektet har vært det desidert største utviklingsprosjektet ved Forsvarets forskningsinstitutt (FFI) noen gang. Det har også vært betegnet som det største forsknings- og utviklingsprosjekt i Norge på 1960-1970-tallet. ... -
Pensjonskostnader i forsvarssektoren - overslagsberegninger av "usynlige" kostnader for forsvarssektorens personell
(2016-01-17)Forsvarssektorens pensjonskostnader bæres i dag langt på vei av folketrygden og av Statens pensjonskasse, uten at Forsvarsdepartementet behøver å betale. I forbindelse med en kommende revisjon av pensjonssystemet i ... -
Perfluorerte alkylerte stoffer (PFAS) - en litteraturstudie om PFAS i akvatiske miljø, effekter og kunnskapshull
(2017-06-02)Perfluorerte alkylerte stoffer (PFAS) er organiske fluorerte forbindelser brukt i en rekke industrielle og kommersielle produkter, deriblant brannskum. På grunn av omfattende bruk, persistens i miljøet og bioakkumulerende ... -
Perforation of concrete targets
(2003)During construction of concrete buildings for military purposes, one is interested in minimizing the potensial damage caused by an impacting projectile. To achieve this, it is necessary to use a wall thickness that either ... -
Performance analysis of the proposed new restoring camera for hyperspectral imaging
(2010)This report investigates the performance of the proposed new restoring camera for hyperspectral imaging. The suggested camera will eliminate keystone in the postprocessing of the data with no resolution loss and will be ... -
A Performance Characteristic for Net Light Collection in Hyperspectral and Conventional Cameras: A*
(2022-12-09)The signal-to-noise ratio of modern cameras under normal operating conditions tends to be limited by “photon noise” originating from the random arrival of photons. For best signal-to-noise ratio, it is desirable to collect ... -
Performance evaluation of high-volume electret filter air samplers in aerosol microbiome research
(2020)Background Reliable identification and quantification of bioaerosols is fundamental in aerosol microbiome research, highlighting the importance of using sampling equipment with well-defined performance characteristics. ... -
Performance of a low-latency repeater jammer implemented on an SDR
(2023-11-23)Frequency-hopping spread-spectrum (FHSS) radio systems change their radio frequency (RF) rapidly to decrease their susceptibility to jamming. Time-correlated jammers have the ability to jam FHSS systems much more efficiently ... -
Performance of a Multiband Passive Bistatic Radar Processing Scheme - Part II
(2012)Simulations based on real-life FM radio waveforms showed that the algorithm is capable of improving range resolution, and thus the accuracy, according to theory for single scatterers as is summarized. The performance of ... -
Performance of drag force models for shock-accelerated flow in dense particle suspensions
(2021-04)Models for prediction of drag forces within a particle cloud following shock-acceleration are evaluated with the aid of results from particle-resolved simulations in order to quantify how much the disturbances introduced ... -
Performance testing of STANAG 4406 (Military messaging) using IP over HF
(2005)This report is the final summary of a test activity of Project 822 SIGVAT HF. The STANAG 4406 (Military Messaging) and its tactical protocol profile has been tested over an HF link supporting IP. The automated HF technologies ... -
Periodisk avrenning av tungmetaller - en feltundersøkelse gjort ved Steinsjøen skytefelt
(2003)This report presents a study of Pb, Cu and Sb contamination of a small stream at Steinsjøen shooting range in Norway. The main purpose of the study was to investigate the dissolved heavy metal concentration during episodic ... -
The perirhinal cortex of rats: An intricate area for microinfusion of anticonvulsants against soman-induced seizures
(2013)Microinfusion of anticonvulsants into the perirhinal cortex through 1 guide cannula in each hemisphere only invades a small area of this seizure controlling site in rats exposed to soman. The purpose of the present study ... -
Permanent readiness units in the Russian Armed Forces
(2009)The Russian Armed Forces are currently undergoing a process of professionalisation, the aim of which is to build a 70 per cent professional force, retaining only 30 per cent conscript soldiers. The process of professionalising ...
