Abstraction-decomposition space for critical infrastructure systems: A framework for infrastructure planning and resilience policies
(2022-04-20)The objective of this work has been to propose a framework that will aid governments with the development of more coherent and effective infrastructure planning and resilience policies through a system-of-systems approach ... -
The Rapidly Exploring Random Tree Funnel Algorithm
(2022-03-17)This paper shows the feasibility of combining robust motion primitives generated through the Sums Of Squares programming theory with a discrete Rapidly exploring Random Tree algorithm. The generated robust motion ... -
Formalizing swarm security
(2022-01-24)Cheap, capable processors are becoming readily available, and these are being deployed to a wide variety of applications, ranging from internet-enabled refrigerators to swarms of specialised drones. As often is the case ... -
Probabilistic estimation of merchant ship source levels in an uncertain shallow-water environment
(2021-11-13)The estimation of ship source levels (SSLs) in shallow-water environments can be complicated by sound interaction with the seabed. Uncertainty in seabed properties influences SSL estimates, and it is of interest to mitigate ... -
Urban Terrorism in the Arab World: Introducing a Dataset of Jihadist Attack Plots in Jordan
(2021-09-21)Few regions have been more plagued by terrorism than the Arab world. However, knowledge of the phenomenon’s nature is limited by a lack of attack plot data for most Arab countries. This article contributes to addressing ... -
Augmenting Radar Doppler Resolution with Neural Networks
(2021-12-08)In order to generate high-resolution Doppler profiles a radar needs to emit a large number of pulses within a coherent processing interval (CPI). For a radar operating in demanding scenarios it can be difficult to sustain ... -
High Unemployment and the Armed Forces: The Costs and Benefits of Recruiting Military Personnel in Norway
(2021-12-07)The SARS-CoV-2 pandemic, the subsequent non-pharmaceutical interventions by governments to reduce the transmission of the coronavirus, and adjusted consumer behaviors have resulted in high unemployment rates worldwide. In ... -
NATO Federated Coalition Cloud with Kubernetes: A National Prototype Perspective
(2021-10)In NATO, the IST-168 research task group (RTG) “Adaptive Information Processing and Distribution To Support Command and Control” aims to investigate cloud computing at the tactical edge from a coalition force perspective. ... -
Military Applications of Internet of Things: Operational Concerns Explored in Context of a Prototype Wearable
(2021-10)Internet of Things (IoT), due to its inherently automated behavior and low development costs, coupled with the emergence of wireless technologies combined with small-sized hardware, has become one of the defining ... -
Holmium-doped fiber amplifier for pumping a ZnGeP2optical parametric oscillator
(2021-03-03)We present a holmium-doped all-fiber master oscillator power amplifier (MOPA) system operating at 2108 nm targeting optical frequency conversion applications. The MOPA delivers pulses of 0.52 mJ energy at 10 kHz repetition ... -
Fusing of a continuous output PDR algorithm with an ultrasonic positioning system
(2021-12-09)The availability of inertial navigation sensors in smartphones has facilitated the development of pedestrian dead reckoning (PDR) models on a large scale. These models often consist of a step detection algorithm combined ... -
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 ... -
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 ... -
Systemic approaches for emission reduction in industrial plants based on physical accounting: example for an aluminium smelter
(2022-01-22)Greenhouse gas (GHG) accounting in industrial plants usually has multiple purposes, including mandatory reporting, shareholder and stakeholder communication, developing key performance indicators (KPIs), or informing ... -
Pragmatism and Purism in Jihadist Governance: The Islamic Emirate of Azawad Revisited
(2022-01-02)The Islamic Emirate established in northern Mali in 2012 was brought down less than a year later by a French military intervention, pro- voked by the Emirate’s belligerent posture. This article explains why the leaders of ... -
The First GAEN-Based COVID-19 Contact Tracing App in Norway Identifies 80% of Close Contacts in “Real Life” Scenarios
(2021-11-17)The coronavirus disease 2019 (COVID-19) response in most countries has relied on testing, isolation, contact tracing, and quarantine (TITQ), which is labor- and time-consuming. Therefore, several countries worldwide launched ... -
Severity Scoring of Behavioral Responses of Sperm Whales (Physeter macrocephalus) to Novel Continuous versus Conven tional Pulsed Active Sonar
(2021-04-19)Controlled exposure experiments (CEEs) have demonstrated that naval pulsed active sonar (PAS) can induce costly behavioral responses in cetaceans similar to antipredator responses. New generation continuous active sonars ... -
In situ performance prediction of a coherent acoustic modem in a reverberant environment
