Cancer Development and Damped Electromagnetic Activity [PDF]
Applied Sciences, 2020 Cancer can be initiated in a cell or a fibroblast by short-circuiting of the cellular electromagnetic field by various fibers, parasitic energy consumption, virus infections, and mitochondrial defects, leading to a damped cellular electromagnetic field. Except short-circuiting (e.g., by asbestos fibers), the central process is mitochondrial dysfunction

Virtual Energy Management for Physical Energy Savings in a Legged Robot Hopping on Granular Media
Frontiers in Robotics and AI, 2021 We discuss an active damping controller to reduce the energetic cost of a single step or jump of dynamic locomotion without changing the morphology of the robot. The active damping controller adds virtual damping to a virtual leg spring created by direct-

Active Vibration Control Strategy for Online Application in a Range Extender
IEEE Access, 2023 Noise, vibration and harshness are a big issue for hybrid vehicles especially in range extenders. Traditional vibration control and active damping control are generally used for suppressing vibration.

A Unified Active Damping for Grid and Converter Current Feedback in Active Front End Converters
IEEE Access, 2022 The Active Front End (AFE) is interconnected to the grid with an LCL filter to reduce the switching harmonics. Possible resonances induced by the LCL filter can be damped using Active Damping (AD). In AFE applications, the current sensor can be placed on

Robust Active Damping Control for LCL-Type Shunt Active Power Filters
IEEE Access, 2022 A dual-loop current control is discussed for LCL-type shunt active power filters (APFs), where inverter-side current feedback and point of common coupling (PCC) voltage feedforward both provide active damping (AD) effects for LCL resonance.
