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 ...
Multimodal change monitoring using multitemporal satellite images
(2021-09-12)
The main objective of this study is to monitor the land infrastructure growth over a period of time using multimodality of
remote sensing satellite images. In this project unsupervised change detection analysis using ITPCA ...
Optimization of active sonar parameters in a measured environment
(2021-09-13)
ABSTRACT
Sonar operation in coastal waters is challenging due to high false alarm rates and strongly varying sonar conditions. Optimal choices for sonar design and pulse characteristics depend strongly on target location ...
Detection of Point Scatterers in Medical Ultrasound
(2021-11-19)
We present an overview of the detection of point scatterers in ultrasound images and suggest strategies for evaluating and measuring the detection performance. We use synthetic aperture Field II simulations of a point ...
Leveraging network-centric strategic goals in capabilities
(2021-04-19)
The vision of network-centric operations is to increase operational capabilities through networked collaboration. NATO and its member nations state this vision in strategic documents at a very high level of abstraction. ...
Hvorfor så ambivalent? USAs politikk overfor EUs forsvarsambisjoner
(2021-01-19)
Artikkelen diskuterer forholdet mellom den europeiske integrasjonsprosessen og det atlantiske samarbeidet under USAs ledelse. Problemstillingen artikkelen besvarer er hvilke tilnærminger Trump-administrasjonen har hatt til ...
Surgical helmets can be converted into efficient disinfectable powered air-purifying respirators
(2021-12-25)
Background
Filtering facepiece respirators often fail to provide sufficient protection due to a poor fit. Powered air-purifying respirators (PAPRs) are not designed for healthcare personnel, and are challenging to disinfect. ...
Relative Heading Estimation for Pedestrians Based on the Gravity Vector
(2021-03-15)
Inertial navigation of pedestrians carrying a smart device is a core component of many indoor positioning systems. While infrastructure-based solutions typically depend on an installation of dedicated hardware, inertial ...
A containerised approach to labelled C&C traffic
(2022-01-24)
A challenge for data-driven methods for intrusion detection is the availability of high quality and realistic data, with ground truth at suitable level of granularity to train machine learning models. Here, we explore a ...
German-Norwegian relations in security and defence? What kind of partnership?
(2021-03-17)
The article contributes to the debate on European defence cooperation and integration by analysing the German–Norwegian security and defence partnership. I define this partnership as being based upon mutual interests and ...
