RIFTA: A Robust Iterative Fourier Transform-based dwell time Algorithm for ultra-precision ion beam figuring of synchrotron mirrors

Scientific Reports, 2020
With the rapid evolution of synchrotron X-ray sources, the demand for high-precision X-ray mirrors has greatly increased. Single nanometer profile error is required to keep imaging capability at the diffraction limit. Ion Beam Figuring (IBF), as a highly

The Exact Correspondence between Phase Times and Dwell Times in a Symmetrical Quantum Tunneling Configuration [PDF]

, 2007
The general and explicit relation between the phase time and the dwell time for quantum tunneling or scattering is investigated. Considering a symmetrical collision of two identical wave packets with an one-dimensional barrier, here we demonstrate that ...

Rectangular Potentials in a Semi-Harmonic Background: Spectrum, Resonances and Dwell Time [PDF]

, 2011
We study the energy properties of a particle in one dimensional semi-harmonic rectangular wells and barriers. The integration of energies is obtained by solving a simple transcendental equation.

A Tool to Retrieve Alert Dwell Time from a Homegrown Computerized Physician Order Entry (CPOE) System of an Academic Medical Center: An Exploratory Analysis

Applied Sciences, 2021
Alert dwell time, defined as the time elapsed from the generation of an interruptive alert to its closure, has rarely been used to describe the time required by clinicians to respond to interruptive alerts.

Mechanical Properties and Microstructure of Friction Stir Spot Welded 6082-T6 Aluminium Alloy Joint [PDF]

MATEC Web of Conferences, 2019
Friction stir spot welding (FSSW) can substitute resistance spot welding (RSW) to avoid the problem due to melting materials during welding. In this investigation, a friction stir spot welded 6082 T6 joint was made to study the effect of pin diameter and

Generalized stability criteria of switched linear systems with time-varying delays

Results in Control and Optimization, 2023
In this paper, the global exponential stability problem of the switched linear system with time-varying delays is considered. We establish a new stability criterion for the switched linear time-delay system under the Φ-dependent average dwell time ...
