Cavity expansion theory applied to the penetration of high speed spheres into weak targets
(2002)As a first attempt at identifying a tissue model for use in wound ballistic simulations a study of the deceleration of spherical steel projectiles in soap has been carried out. Experimental data were compared to numerical ... -
CBAM: A Contextual Model for Network Anomaly Detection
(2021)Anomaly-based intrusion detection methods aim to combat the increasing rate of zero-day attacks, however, their success is currently restricted to the detection of high-volume attacks using aggregated traffic features. ... -
CEP-stable few-cycle pulses with more than 190 μJ of energy at 100 kHz from a noncollinear optical parametric amplifier
(2017)Noncollinear optical parametric amplifiers (NOPAs) have become the leading technique for the amplification of carrier-envelope phase (CEP)-stable, few-cycle pulses at high repetition rate and high average power. In this ... -
Cerebrospinal Fluid Phosphate in Delirium after Hip Fracture
(2017)Aims: Phosphate is essential for neuronal activity. We aimed to investigate whether delirium is associated with altered phosphate concentrations in cerebrospinal fluid (CSF) and serum. Methods: Seventy-seven patients with ... -
Cetaceans and naval sonar : the 3S-2009 cruise report
(2009)Forsvaret har utrykt behov for å få kartlagt sjøpattedyrs følsomhet overfor sonarsignaler, også atferdsmessige påvirkninger. 3S-konsortiet, som for tiden består av fire partnere, FFI, Woods Hole Oceanographic Institution ... -
Challenges for Risk and Security Modelling in Enterprise Architecture
(2019-11-19)From our experience cooperating with the Norwegian Armed Forces, we outline two interconnected challenges for modelling risk and security in an enterprise architecture: (1) modelling what is protected and why it is protected ... -
Challenges in Seafloor Imaging and Mapping With Synthetic Aperture Sonar
(2011)Synthetic aperture sonar (SAS) is emerging as an imaging technology that can provide centimeter resolution over hundreds-of-meter range on the seafloor. Although the principle of SAS has been known for more than 30 years, ... -
Challenges of Labelling Unknown Seabed Munition Dumpsites from Acoustic and Optical Surveys: A Case Study at Skagerrak
(2022-05-31)The disposal of unexploded ordnance (UXOs) at sea is a global problem. The mapping and remediation of historic UXOs can be assisted by autonomous underwater vehicles (AUVs) carrying sensor payloads such as synthetic aperture ... -
Change detection in SAR-images from the TerraSAR-X satellite with main focus towards harbors and container terminals
(2013-10-01)The detection of changes or no change in a set of images of the same scene recorded at different times is of importance in many applications. The time scale could be from seconds to days or months. Man-made constructions ... -
Change detection on shipwrecks using synthetic aperture sonar – North Sea Wrecks Task 3.5 Deep Water Case Study
(2022-12-16)During the last 15 years, synthetic aperture sonar (SAS) technology has matured substantially. Today SAS represents state-of-the-art in seabed imaging and mapping when used on autonomous underwater vehicles (AUV). SAS ... -
Change Detection Using Time and Look Angle Series of Geocoded TanDEM-X Staring Spotlight Images
(2021-03-26)This article describes the analysis of changes in time and look angle series of TanDEM-X (TDX) and TerraSAR-X (TSX) staring spotlight images over the regions around Kjeller near Oslo in Norway and the town Nikel in Russia ... -
Changes in dive behavior during sonar exposure in killer whales, pilot whales and sperm whales.
(2012)Anthropogenic underwater sound in the environment might potentially affect the behavior of marine mammals enough to have an impact on their reproduction and survival. Diving behavior of four killer whales (Orcinus orca), ... -
Changes in fibrinogen availability and utilization in an animal model of traumatic coagulopathy
(2013)Background Impaired haemostasis following shock and tissue trauma is frequently detected in the trauma setting. These changes occur early, and are associated with increased mortality. The mechanism behind trauma-induced ... -
Changes in inoperability for interdependent industry sectors in Norway from 2012 to 2017
(2021-03)The purpose of this work has been to investigate changes in interdependencies between Norway's mainland industry sectors and how it might affect national security. To this end, the interdependencies were analysed by using ... -
Changes in intestinal microbiota composition and metabolism coincide with increased intestinal permeability in young adults under prolonged physiologic stress
(2017)The magnitude, temporal dynamics, and physiological effects of intestinal microbiome responses to physiological stress are poorly characterized. This study used a systems biology approach and a multiple-stressor military ... -
Channel sounding for acoustic communications : techniques and shallow-water examples
(2011-04-11)This report deals with channel soundings, which are measurements of the time-varying impulse response of a propagation medium. The treatment focuses on underwater acoustic channels, the characterization of which is ... -
Characterisation of a munition grade lewisite mixture
(2001)The three compounds trans-lewisite I, all-trans-lewisite II and all-trans-lewisite III have been identified in a munition grade lewisite mixture probably originating from World War II. all-trans-Lewisite II and ... -
The characteristics of successful military IT projects: a cross-country empirical study
