Twirre is a new architecture for mini-UAV platforms designed for autonomous flight in both GPS-enabled and GPS-deprived applications. The architecture consists of low-cost hardware and software components. High-level control software enables autonomous operation. Exchanging or upgrading hardware components is straightforward and the architecture...

The use of a geotechnical centrifuge for properly capturing the mechanisms in the sand adjacent to a foundation pile is well established. Larger centrifuge facilities were previously preferred over small centrifuges, because of the difficulties of the required miniature instrumentation. The technology since then has moved on and recent technical...

The current paper presents a novel experimental method which is able to capture the effects of suffusion by substitution of the fines in a sample by salt of a similar grain size. The setup is tailored to optically capture the change in soil structure behind a glass window in a plane strain strongbox using a digital camera. Subsequently, digital...
