Terrain Classification for Planetary Rovers Using Wireless In‐Wheel Sensor Modules and Machine Learning

Journal of Field Robotics, EarlyView.
ABSTRACT Safe and reliable mobility over different kinds of ground is important for planetary rovers on space missions. Since terrain changes might affect the mobility of the rover, energy consumption, and safety, detecting the type of ground in real‐time is vital.

Cameras do not always take a full picture: wolf activity patterns revealed by accelerometers versus road‐positioned camera traps

Remote Sensing in Ecology and Conservation, EarlyView.
Camera traps have become an increasingly popular non‐invasive alternative to animal‐attached devices for studying wildlife behaviour. This study compared wolf (Canis lupus) activity patterns derived from collar accelerometers and road‐positioned camera traps and revealed strong overall agreement but also important seasonal and diel mismatches between ...

Sleep assessment using accelerometry: Not all algorithms are equal

Sleep Research, EarlyView.
Abstract Study objectives Accelerometry devices are increasingly used to assess sleep. However, whether different algorithms provide consistent estimates remains uncertain. This study compared sleep parameters derived from two accelerometry‐based algorithms and a self‐reported sleep journal.

Experimental Investigations on the Impact of Operational Conditions on Bubble Dynamics and the Resulting Vibrations in Gas‐Stirred Ladles

steel research international, EarlyView.
This study applies sensitive vibration sensors to investigate gas bubble behavior in liquid metal during argon injection. Analysis of vibration signals provides insights into bubble evolution and the influence of gas flow and surface pressure. The results provide a basis for improved vibration‐based two‐phase flow models, enhancing accuracy in ...

Large‐scale tests of 50‐year‐old prestressed concrete bridge girders

Structural Concrete, EarlyView.
Abstract An experimental investigation has been carried out as part of the BRIDGE|50 research project, focusing on large‐scale loading tests performed on five 50‐year‐old prestressed concrete (PC) girders. The study aimed at evaluating the structural response of five girders retrieved from a viaduct in the urban area of Turin, Italy, subjected to 4 ...
