This paper focuses on the energy costs of using a control system to follow a specific trajectory as opposed to directly choosing the inputs in an open-loop sense to achieve a specific trajectory. Results show that the PID controller will use 7–13%

A Vibratory, Subresonant Diagnostic Device to Measure Dental Implant Stability Via Angular Stiffness
Publikováno v:
Journal of Medical Devices. 15
Stability of a dental implant reflects quality of osseointegration between the implant and its surrounding bone. While many methods have been proposed to characterize implant stability, angular stiffness at the neck of the implant has been proven to

This paper studies the effect of rotor blade aerodynamics and rotor grouping on the accuracy of open-loop simulations with respect to generated trajectories and energy consumption for multi-rotor drones. To examine these effects an 18-rotor high perf

Both flapping insect and robotic wings undergo structural deformation during flight. Deformation gives rise to considerable strain energy storage, and this energy can be recovered to accelerate/decelerate the wing over a flapping cycle. This mechanis

Piezoelectric thin-film micro-sensors and actuators often appear in the form of a diaphragm anchored around its entire boundary. When a micro-device is scaled down in size, its sensitivity reduces and natural frequency increases, drastically lowering
