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 ... -
Spectral properties of multilayered oak leaves and a camouflage net: experimental measurements and mathematical modelling
(2021-09-21)The development of state-of-the-art surveillance technology forces nations to develop camouflage with advanced capabilities. Owing to the abundance and wide distribution of leaves, their spectral properties are often ... -
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 ... -
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. ... -
3D Rendering of Shipwrecks from Synthetic Aperture Sonar
(2021-10-25)Synthetic aperture sonar (SAS) bathymetric mapping provides centimeter-scale horizontal resolution of the seafloor. Typically, SAS data has been visualized as 2D images or gridded 2.5D surfaces, but it can also be plotted ... -
A Bayesian Network Approach to Evaluating the Effectiveness of Modern Mine Hunting
(2021-10-29)This paper describes a novel technique for estimating how many mines remain after a full or partial underwater mine hunting operation. The technique applies Bayesian fusion of all evidence from the heterogeneous sensor ... -
Small-scale fire performance assessment of intumescent coatings on metal tubes containing ammonium nitrate. A stepping-stone towards their application as a fire safety measure on road transportation tanks?
(2021-11)Ammonium nitrate is used in vast amounts globally, first and foremost as a component of fertilizers and explosive formulations. This usage necessitates its transportation which, as for most hazardous materials, involves ... -
Reactive Collision Avoidance for Nonholonomic Vehicles in Dynamic Environments with Obstacles of Arbitrary Shape
(2021-11-01)Over the recent years, there has been an increasing interest in autonomous systems. Consequently, the problem of avoiding static and dynamic obstacles without human interference has gained a lot of attention. Avoiding ... -
Ultrafast Pulse Compression in Bulk with > 20 Times Spectral Broadening Factor from a Single Stage
(2021-11-01)We introduce the combination of multi-pass cell and multi-plate spectral broadening. We demonstrate the compression of 110-μJ pulses from 900-fs to 60-fs in a single stage and report broadening to 38-fs transform-limit by ... -
Spectral characteristics of moist birch leaves and synthetic materials: experimental studies and evaluation of models
(2021-11-09)The optical depth of biomaterials and natural backgrounds varies with their environment and incoming light properties. Deciduous trees, for instance, have canopy thicknesses that vary significantly from one place to another. ... -
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 ... -
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 ... -
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 ... -
Quantification of aerosol dispersal from suspected aerosol-generating procedures
(2021-12-06)Background Oxygen-delivering modalities like humidified high-flow nasal cannula (HFNC) and noninvasive positive-pressure ventilation (NIV) are suspected of generating aerosols that may contribute to transmission of disease ... -
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 ... -
Augmenting Radar Doppler Resolution with Neural Networks
