A Calibration Algorithm for Microelectromechanical Inertial Sensors
Известия высших учебных заведений России: Радиоэлектроника, 2022 Introduction. Systematic errors of microelectromechanical (MEMS) inertial sensors, such as those related to zero drift, scale factor, and nonorthogonality of sensitive axes, are the main sources of errors in strapdown inertial navigation systems (SINS ...

Discrete element models for understanding the biomechanics of fossorial animals
Ecology and Evolution, Volume 12, Issue 9, September 2022., 2022 The dynamics (forces, work, and soil displacements) of burrowing by North American Badger were predicted for different forms of badger claw and manus, using numerical models. The results indicate that the modern manus with 5 digits has indeed advantages.

Selection of the Material for the Sensitive Elements of SAW-based Accelerometers
Известия высших учебных заведений России: Радиоэлектроника, 2020 Introduction. At the present, sensors based on surface acoustic waves (SAW) is a rapidly developing direction and a promising replacement for classical sensors, especially in those areas where long-term performance of latter is questionable.

Testing and calibration of smart pebble for river bed sediment transport monitoring [PDF]
, 2007 The Smart Pebble (smart particle), SP, has been developed for the past two years to monitor sediment transport in riverbeds. The implementation is based on use of small size and low cost acceleration and angular motion sensors. In this stage, the project

Wireless Communications and Mobile Computing, Volume 2022, Issue 1, 2022., 2022 Aerobics is an indispensable part of school teaching. Aerobics can exercise the human body’s flexibility, muscle extension, and cardiopulmonary function. However, there are many details in the aerobics movements that need attention, so this article mainly studies the perception and recognition of the upper limb movement trajectory of aerobics.

Large amplitude dynamics of micro/nanomechanical resonators actuated with electrostatic pulses [PDF]
, 2010 International audienceIn the field of resonant NEMS design, it is a common misconception that large-amplitude motion, and thus large signal-to-noise ratio, can only be achieved at the risk of oscillator instability.
