    Opinion Dynamics Modelling: Distinct Attraction and Repulsion Topologies Highlight Quantitative Effects of Trolling

    Abstract We introduce a model of opinion dynamics based on networked nonlinear differential equations. The model combines a linear attraction with a repulsive hyperbolic tangent interaction, labelled controversialness . For low controversialness, the model displays universal cons...

    UAS engagement decision modelling for directed energy systems

    The problem of countering swarms of uncrewed aerial systems has become of increased importance in modern military settings. This is because small and agile uncrewed aerial systems may be deployed quite easily and used for destroying infrastructure or attacking enemy positions. Su...

    Experimental investigation of ship airwake with wave-induced motions

    The turbulent airwake over a moving ship is experimentally investigated in a wind-wave facility using a 1:200 scaled NATO-GD model. Three motion scenarios are examined: heaving, pitching, and combined motions, naturally driven by incoming waves. Particle Image Velocimetry measure...

    Measuring Ocean Surface Waves

    Abstract Propagating waves on the ocean surface can be represented as a stochastic process whose statistics are characterized by a spectrum. This paper reviews methods for measuring the wave spectrum and related quantities. Observations begin by sensing fluid dynamical properties...

    Evolution of spectra and convection velocities of a turbulent boundary layer over an axisymmetric body

    Time-resolved particle image velocimetry and hot-wire anemometry are employed to examine the spectral characteristics and frequency-dependent convection velocities of a turbulent boundary layer developing over an axisymmetric body of revolution subjected to varying pressure gradi...

    How to Benchmark Post-Quantum Accelerators

    With the recent standardisation of several post-quantum cryptographic (PQC) algorithms, there is an increased focus within the hardware research community to investigate efficient accelerator designs. However, it is difficult to determine whether the reported results are directly...

    Cognitive Performance in Young Adults During Three Consecutive Days of Simulated Occupational Heat Stress: An Exploratory Study

    INTRODUCTION: Global increases in occupational heat exposure are raising concerns about worker safety and cognitive performance during prolonged and repeated shifts. At present, the cumulative effects of repeated heat exposure on cognitive performance remain unclear. This explora...
