Spawning Atlantic cod (Gadus morhua L.) exposed to noise from seismic airguns do not abandon their spawning site
(2022-11-15)Seismic airgun surveys may disturb and displace fish at large ranges. If such displacement causes fish to abandon spawning grounds, reproductive success could be impacted. To investigate whether airgun sound causes cod ... -
Towards data-driven autonomous cyber defence for military unmanned vehicles - threats & attacks
(2022-11-28)Unmanned vehicles with varying degrees of autonomy will likely change the way military operations can be conducted, but they also introduce risks that require new ways of thinking security. In particular, the safety ... -
Collision Avoidance for Underactuated Surface Vehicles in the Presence of Ocean Currents
(2022-11-29)This paper considers the problem of collision avoidance for surface vehicles moving under the influence of ocean currents. The vehicles we consider have underactuated dynamics, where the vehicle cannot directly control its ... -
Big Data Solutions on Tactical Infrastructure
(2022-12-01)In this paper, we discuss the need for explainable artificial intelligence (AI) in defense systems. Further, we elaborate on the need for Big Data solutions to support AI on tactical infrastructure, and discuss an ... -
Typical Products for Outside Audiences: The Role of Typicality When Products Traverse Countries
(2022-12-02)While organization theorists have established the importance of typicality, most studies examine situations where producers and audiences dwell within the same category system (e.g., a country, industry, or market). ... -
A Performance Characteristic for Net Light Collection in Hyperspectral and Conventional Cameras: A*
(2022-12-09)The signal-to-noise ratio of modern cameras under normal operating conditions tends to be limited by “photon noise” originating from the random arrival of photons. For best signal-to-noise ratio, it is desirable to collect ... -
Realising benefits in public IT projects: A multiple case study
(2022-12-13)Information Technology (IT) investments in the public sector are large, and it is essential that they lead to benefits for the organisations themselves and wider society. While there is evidence suggesting a positive ... -
Radio-Frequency Interference Considerations for Utility of the Galileo E6 Signal Based on Long-Term Monitoring by ARFIDAAS
(2023)The extent to which navigation signals in the E6 band may be impacted by shared spectrum allocations might be underappreciated. This paper presents top-level observations from a multi-year international radio frequency ... -
The characteristics of successful military IT projects: a cross-country empirical study
(2023)In the armed forces, successful digitalizationis crucial to ensure effective operations. Much of the existing literature on project factors during the planning and execution phases of public IT projects do not focus ... -
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 ... -
MIMO synthetic aperture sonar: Benefits and limitations
(2023-01-16)The use of Multiple Input Multiple Output (MIMO) orthogonally coded waveforms sharing the same bandwidth, has the potential to increase area coverage rate in synthetic aperture sonar (SAS). The disadvantage is cross-talk ... -
Towards XAI in the SOC – a user centric study of explainable alerts with SHAP and LIME
(2023-01-26)Many studies of the adoption of machine learning (ML) in Security Operation Centres (SOCs) have pointed to a lack of transparency and explanation – and thus trust – as a barrier to ML adoption, and have suggested ... -
LADEMU: a modular & continuous approach for generating labelled APT datasets from emulations
(2023-01-26)Development and evaluation of data-driven capabilities for both threat hunting and intrusion detection require high-quality and up-to-date datasets. The generation of such datasets poses multiple challenges, which has led ... -
HYPSO-1 CubeSat: First Images and In-Orbit Characterization
(2023-01-28)The HYPSO-1 satellite, a 6U CubeSat carrying a hyperspectral imager, was launched on 13 January 2022, with the Goal of imaging ocean color in support of marine research. This article describes the development and current ... -
Exact Two-Component TDDFT with Simple Two-Electron Picture-Change Corrections: X-ray Absorption Spectra Near L- and M-Edges of Four-Component Quality at Two-Component Cost
(2023-02-01)X-ray absorption spectroscopy (XAS) has gained popularity in recent years as it probes matter with high spatial and elemental sensitivities. However, the theoretical modeling of XAS is a challenging task since XAS spectra ... -
Few-cycle pulse generation by double-stage hybrid multi-pass multi-plate nonlinear pulse compression
(2023-02-10)Few-cycle pulses present an essential tool to track ultrafast dynamics in matter and drive strong field effects. To address photon-hungry applications, high average power lasers are used which, however, cannot directly ... -
