Characterization of the public transit air microbiome and resistome reveals geographical specificity
(2021-05-26)Background The public transit is a built environment with high occupant density across the globe, and identifying factors shaping public transit air microbiomes will help design strategies to minimize the transmission of ... -
Characterization of Variable Density 3D Printed Materials for Broadband GRIN Lenses
(2017)In this work we design, simulate, manufacture and measure blocks made of variable density plastic. The density is controlled through varying the size of small cubes at the intersections of a fine grid. This structure is ... -
Characterizing the dynamic range of a hyperspectral camera
(2021-04-12)The dynamic range of a hyperspectral camera can have a strong impact on the quality and integrity of the collected spectra. For the image sensor chip alone, the dynamic range is the ratio between the saturation level and ... -
Cheetah calculations of GA BAMO candidate compositions
(2015-12-02)Norway’s main objective in the EDA project No B-0585-GEM2-GC “Formulation and Production of New Energetic Materials” was to synthesize different new energetic binders built of GA and BAMO polymers. Before starting ... -
Chemical warfare agents and their interactions with solid surfaces
(2013-03-01)This literature study describes the interactions of chemical warfare agents (CWA) with materials. The materials of interest are various construction materials (concrete, plastics) and different types of surface finishing ... -
Chemoselective O-acylation of hydroxyamino acids and amino alcohols under acidic reaction conditions: History, scope and applications
(2015)Amino acids, whether natural, semisynthetic or synthetic, are among the most important and useful chiral building blocks available for organic chemical synthesis. In principle, they can function as inexpensive, chiral and ... -
China's nuclear weapons programme
(2013-07-15)China has been a nuclear weapons power since it conducted its first nuclear test explosion in 1964. This means that China is one of the five states that are allowed to keep a nuclear weapons arsenal under the Treaty of ... -
Chirped pulses sum frequency generation for deep-UV picosecond pulse shaping
(2012)We show by experiments and simulations that properly chirped laser pulses enable efficient and broadband sum frequency generation in nonlinear crystals. We achieved high energy, picosecond deep-UV pulses with spectral ... -
Choice of approaches in developing novel medical countermeasures for nerve agent poisoning
(2014)During the establishment of a research branch, all relevant matters encountered will be of interest to study. After having acquired a body of basal knowledge, it becomes possible to derive ideas or hypotheses for further ... -
Civilian and Private Actors’ Support of Ukrainian National Resistance
(2022-09-16)Civilian and private actors play an important role in Ukrainian national resistance efforts and are likely to be a feature of future conflicts. Studying their role in national resistance is therefore relevant. By identifying ... -
Classification based on fast and robust approximations to order statistics
(2020-04-22)A test system with four cameras in the infrared and visual spectra is under development at FFI (The Norwegian Defence Research Establishment). The system may be mounted on a jet aircraft or may be used in a land-based ... -
Classification of acoustically stable areas using empirical orthogonal functions - examination of stability methods
(2011-11-08)Overview and control of the oceanographic and acoustic variations are very important in underwater warfare. We have developed a method for dividing an area into smaller subareas that can be represented by a single vertical ... -
Classification of birds and UAVs based on radar polarimetry
(2016)This letter aims to show the potential of using polarimetric parameters to distinguish between large birds and unmanned aerial vehicles (UAVs) of comparable size in the context of a modern long-range air defense radar. ... -
Classification of Ships Using Real and Simulated Data in a Convolutional Neural Network
(2016)Convolutional neural networks (CNNs) have recently been applied successfully in large scale image classification competitions for photographs found on the Internet. As our brains are able to recognize objects in the images, ... -
Clostridium botulinum Group I Strain Genotyping by 15-Locus Multilocus Variable-Number Tandem-Repeat Analysis
(2011)Clostridium botulinum is a taxonomic designation that encompasses a broad variety of spore-forming, Gram-positive bacteria producing the botulinum neurotoxin (BoNT). C. botulinum is the etiologic agent of botulism, a rare ... -
Cloud influence on maritime surveillance by an optical satellite
(2016-03-03)Disturbing clouds may be a showstopper when planning a maritime surveillance satellite with an optical sensor. When the probability of clouds in any place is in the range of 75 %, it is indeed important to know where the ... -
Cloud-based decision support system for planning military operations
(2020-02-21)When planning a military operation, it is important to explore possibilities and understand consequences of the plan. To this end, wargaming can be used for assessing possible courses of action (COA) for own and enemy ... -
A Cloud-based experimentation and analysis framework for services at the tactical edge
(2022-09-22)In this paper we present an experimentation and analysis framework that utilizes a public cloud infrastructure for most of the experimentation environment but also supports interaction with services installed on servers ... -
Cluster weapons - military utility and alternatives
(2008)This report is made through the sponsorship of the Royal Norwegian Ministry of Foreign Affairs. Its purpose is to get an overview of the military utility of cluster munitions, and to find to which degree their capacity ... -
Clustering evaluation for deinterleaving
(2013-02-23)Deinterleaving is a fundamental step in a lot of processing in ESM and radar systems, enabling users and/or client programs to focus on data from a single emitter at a time, rather than a mixture of data from several ...
