Damping interarea and torsional oscillations using FACTS devices [PDF]
, 2005 A problem of interest in the power industry is the mitigation of interarea and torsional oscillations. Interarea oscillations are due to the dynamics of interarea power transfer and often exhibit poor damping when the aggregate power transfer over a ...

Journal of Polymer Science, EarlyView.This study presents a fast and accurate calculation tool to predict conveying of polymer melts in single‐screw extruders. Integrating generalized sub‐models into network theory allows to represent the complex screw shapes and material behavior more realistically. Tests on an industrial extruder show close agreement with experiments, outperforming older

Direct Measurement of Explosive Impulse From Contact to the Ultra‐Near Field
Propellants, Explosives, Pyrotechnics, EarlyView.ABSTRACT Measurement of impulse from explosive charges in contact and ultra‐near‐field regimes remains poorly characterised due to the short duration of loading, high strain rates, and the difficulty of obtaining direct momentum‐based measurements.

The formation of the quality parameters of the surface layer by ultrasonic
MATEC Web of Conferences, 2018 In work the questions of hardening of a surface layer of a detail by means of ultrasonic fluctuations are opened. The developed device for forming ultrasonic longitudinal-torsional oscillations is described, which makes it possible to substantially ...

Journal of Field Robotics, EarlyView.ABSTRACT People with physical disabilities face significant mobility challenges while climbing uneven surfaces and staircases. In these circumstances, traditional wheelchairs do not provide stable, safely controlled mobility, underscoring the importance of building superior stair‐climbing wheelchairs for both medical and infrastructure purposes.

Intelligent Continuum Micromachines in Complex Confined Spaces
SmartBot, EarlyView.The cover depicts a conceptual design for an intelligent continuum micromachine entering a target capsule used in fusion‐energy research through its slender gas‐fill tube. By combining route‐adaptive deformation, embedded sensing, and a functional end effector, the robot could inspect hidden defects, assess local conditions, and support localized ...

Mixed-mode oscillations with multiple time scales [PDF]
, 2010 Mixed-mode oscillations (MMOs) are trajectories of a dynamical system in which there is an alternation between oscillations of distinct large and small amplitudes.

Small Methods, EarlyView.For the observation of micromechanical devices, a fast imaging technique with high temporal resolution is needed. Here, we demonstrate that a standard scanning electron microscope can be converted into a time‐resolving instrument using a fast detector and a time‐to‐digital converter.
