Identification of airborne bacteria by 16S rDNA sequencing, MALDI-TOF MS and the MIDI microbial identification system
(2015)The aim of this study was to collect and identify airborne bacteria in Norway, Sweden and Finland and to compare three different technologies for identifying collected airborne bacterial isolates: the “gold standard” method ... -
Identification of mixed substances using a random forest regressor to classify THz absorbance spectra
(2018)We report on the development and application of a random forest regressor that not only identifies but also estimates the relative concentrations of substances (one explosive and two simulants), both in one-substance and ... -
Image-aided inertial navigation for an Octocopter
(2018)A typical unmanned aerial system combines an Inertial Navigation System (INS) and a Global Navigation Satellite System (GNSS) for navigation. When the GNSS signal is unavailable, the INS errors grow over time and eventually ... -
Imaging ground sensor system OPAK
(2003-09-18)Architecture and technology of imaging intrusion detection sensor OPAK are presented. Applications and desired features for IDS and UGS are compared. Started developments of OPAK towards an unattended ground sensor system ... -
Imaging radar for navigation and surveillance on an autonomous unmanned ground vehicle capable of detecting obstacles obscured by vegetation
(2019-09-16)The Norwegian Defence Research Establishment (FFI), has developed a multi purpose radar demonstrator for Intelligence, Surveillance and Reconnaissance (ISR) on the Off-road Light Autonomous Vehicle (OLAV) platform. The ... -
The Importance of Significant Others in Preventing Extremism: The Philosophy and Practice of the Swedish Tolerance Project
(2020)This article concerns a specific educational programme to reduce recruitment to racist and extreme organizations in Sweden. The programme is called the Tolerance Project, and it functions as an elective course offered to ... -
Improved active sonar tactical support by through-the-sensor estimation of acoustic seabed properties
(2014)Accurate environmental information is required for obtaining confident sonar performance predictions. This environmental information is, however, often unreliable or unavailable. To support antisubmarine warfare (ASW) ... -
Improved conceptualising of hybrid interference below the threshold of armed conflict
(2023-06-08)European policymakers have identified the need to understand influence operations on social media, cyber-attacks or hidden economic investments – activities that can be characterised as hybrid threats or hybrid warfare. ... -
Improved correction methods for measuring altitude by Radar and Barometer
(2018)Geometric altitude of air targets may be found from radar or barometric measurement. However, radar rays are affected by changes in refractive index gradients which result in non-normal bending of rays. Similarly, precision ... -
Improved discretisation and linearisation of active tension in strongly coupled cardiac electro-mechanics simulations
(2012)Mathematical models of cardiac electro-mechanics typically consist of three tightly coupled parts: systems of ordinary differential equations describing electro-chemical reactions and cross-bridge dynamics in the muscle ... -
Improved estimation of oceanographic climatology using empirical orthogonal functions and clustering
(2013)Vertical profiles of temperature, salinity, and sound speed velocity are used in numerous applications where accurate vertical profiles are crucial. Conventional climatological representations of vertical oceanographic ... -
Improved Passivation Effect Due to Controlled Smoothing of the CdTe-HgCdTe Interface Gradient by Thermal Annealing
(2019-07-11)HgCdTe films grown by liquid phase epitaxy were passivated with CdTe grown by molecular beam epitaxy. A series of annealing tests with different temperatures and durations were then carried out in order to reach a two-fold ... -
Improving the decision-making basis by strengthening the risk assessments of unexploded ordnance and explosive remnants of war
(2023-01-15)For many countries, the legacy of armed conflict in the form of unexploded ordnance has a severe impact on society and daily life, as millions of tonnes of explosive remnants of war represent a grave threat to both the ... -
In operando neutron diffraction study of a commercial graphite/(Ni, Mn, Co) oxide-based multi-component lithium ion battery
(2016)In situ neutron diffraction was employed to investigate the structural evolution of the electrode materials in an ICR 10440 commercial cylindrical lithium-ion battery, which has a discharge capacity of 360 mAh and a nominal ... -
In situ performance prediction of a coherent acoustic modem in a reverberant environment
(2021-07-28)A channel sounding and communications experiment was performed in the Oslofjord, using eight bottom-mounted instrument units deployed in a network configuration. Five units were equipped with a software-defined 4–8-kHz ... -
In-Body to On-Body Ultrawideband Propagation Model Derived from Measurements in Living Animals
(2015)Ultra wideband (UWB) radio technology for wireless implants has gained significant attention. UWB enables the fabrication of faster and smaller transceivers with ultra low power consumption, which may be integrated into ... -
In-operation calibration of clock-bias and intrinsic parameters for pan-tilt-zoom cameras based on keypoint tracking
(2020-09-20)We propose a method for jointly estimating intrinsic calibration and internal clock synchronisation for a pantilt- zoom (PTZ) camera using only data that can be acquired in the field during normal operation. Results show ... -
