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...
