Flexural performance of concrete‐filled steel tubular beams with wood chip aggregate

Structural Concrete, EarlyView.
Abstract This study investigates the flexural performance of concrete‐filled steel tubular (CFST) beams with partial replacement of aggregates by wood chips (0%–25%) through experimental and numerical analysis. This study is novel in that it experimentally and numerically investigates the flexural behavior of CFST beams with partial replacement of ...

Pickin' up good vibrations: a systematic review of footfall detection and analysis in the realm of wildlife surveying

Wildlife Biology, EarlyView.
Exploration of new wildlife surveying methodologies that leverage advances in sensor technology and machine learning has led to tentative research into the application of seismology techniques. This, most commonly, involves the deployment of a footfall trap – a seismic sensor and data logger customised for wildlife footfall.
