A New Rotary Magnetorheological Damper for a Semi-Active Suspension System of Low-Floor Vehicles

open access: yesActuators
This study explores the significance of active suspension systems for vehicles with lower chassis compared to conventional ones, aiming at the development of future automobiles. Conventional linear MR (magnetorheological) dampers were found inadequate in

4D Printing of Complex Structures with a Fast Response Time to Magnetic Stimulus.

open access: yesACS Applied Materials and Interfaces, 2018
A poly(dimethylsiloxane)/Fe (PDMS/Fe) composite ink was developed for reversible four-dimensional (4D) printing to create magnetically responsive three-dimensional (3D) structures with a fast response time for their structure evolvements under external ...

Fluctuations of two-time quantities and non-linear response functions [PDF]

open access: yes, 2010
We study the fluctuations of the autocorrelation and autoresponse functions and, in particular, their variances and co-variance. In a first general part of the Article, we show the equivalence of the variance of the response function with the second ...

The Effect of Ambulance Response Time on Survival Following Out-of-Hospital Cardiac Arrest.

open access: yesDeutsches Ärzteblatt International, 2018
BACKGROUND Out of hospital cardiac arrest (OHCA) is one of the more common causes of death in Germany. Ambulance response time is an important planning parameter for emergency medical services (EMS) systems.

Femtosecond response time measurements of a Cs2Te photocathode

open access: yes, 2017
We present the response time measurements of a Cs2Te photocathode illuminated with two 100 fs duration, variable time separation laser pulses at 266 nm wavelength. The response time was confirmed in dispersive region downstream of a 12-cell standing wave

A short response-time atomic source for trapped ion experiments [PDF]

open access: yes, 2018
Ion traps are often loaded from atomic beams produced by resistively heated ovens. We demonstrate an atomic oven which has been designed for fast control of the atomic flux density and reproducible construction.
