Lamb wave line sensing for crack detection in a welded stiffener [PDF]
, 2014 This paper proposes a novel Lamb wave line sensing technique for crack detection in a welded stiffener. The proposed technique overcomes one of the biggest technical challenges of Lamb wave crack detection for real structure applications: crack-induced ...

The coevolution of board interlock networks and corporate strategic actions
Strategic Management Journal, EarlyView.Abstract Research Summary Studies on board interlock networks are divided into two streams, one examining their dynamics; the other, their consequences. We propose that both phenomena—board interlock dynamics and consequences—are interdependent. Applying structuration theory, we explain and empirically demonstrate how firms' corporate strategic actions

Numerical Simulation of Nonlinear Lamb Waves Used in a Thin Plate for Detecting Buried Micro-Cracks
Sensors, 2014 Compared with conventional linear ultrasonic inspection methods, which are sensitive only to severe defects, nonlinear ultrasonic inspection methods are better for revealing micro-cracks in thin plates.

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.

Journal of the Royal Anthropological Institute, EarlyView.Hair is an integral part of the skin's interface and has sensory capacity. It actively contributes to processes of bodily materialization and facilitates transactional exchange with other social actors and environments, particularly regarding energies and vibrations that can be perceived as subtle matter.
