Dwell time and phase times for transmission and reflection

Physical Review B, 1989
The dwell time ${\ensuremath{\tau}}_{D}$(E) and the transmission and reflection times ${\ensuremath{\tau}}_{T}$(E) and ${\ensuremath{\tau}}_{R}$(E), respectively, associated with the interaction of a particle of energy E with a one-dimensional barrier are currently the subject of considerable controversy.

Dwell time on tableting: dwell time according to force versus geometric dwell time

Pharmaceutical Development and Technology
Dwell time is an important parameter responsible for the material deformation and the mechanical and biopharmaceutical properties of the tablet. Thus, it is widely used for scale-up purposes. The geometric dwell time (GDT) can be assumed based on the shape of the punch head and the diameter and speed of the turret.

The Time in Which We Dwell

Archives of Surgery, 1975
There is a wonderful saying—attributed to the Quakers, I believe—that one should not speak unless he can improve on silence. With this self-admonition, I should like to discuss three topics: (1) the international aspects of cardiovascular surgery and of our Society in particular; (2) the North American Chapter, its resources and its responsibilities ...

Improving Dwell-Based Gaze Typing with Dynamic, Cascading Dwell Times

Proceedings of the 2017 CHI Conference on Human Factors in Computing Systems, 2017
We present cascading dwell gaze typing, a novel approach to dwell-based eye typing that dynamically adjusts the dwell time of keys in an on-screen keyboard based on the likelihood that a key will be selected next, and the location of the key on the keyboard.

Dwell times for light and electrons

Journal of Physics A: Mathematical and General, 1993
Using a time-dependent scattering theory for light the authors obtain expressions for the time that light spends in a finite dielectric medium surrounded by vacuum, the so-called dwell time. Given an incoming wavepacket, they focus upon the light scattered in an arbitrary direction.

Dwell-time control of continuous-time switched linear systems

53rd IEEE Conference on Decision and Control, 2014
This paper analyses the design of switched control of continuous-time switched systems, satisfying dwell-time constraints. These constraints are normally imposed to avoid the undesired phenomenon of chattering, which can damage physical devices used in the implementation of such systems.

Switching Controller Design With Dwell-Times and Sampling

IEEE Transactions on Automatic Control, 2017
We consider the problem of obtaining state dependent switching strategies for switching linear time-invariant systems which satisfy prespecified dwell-time constraints. Continuous-time strategies which yield exponential stability and a guaranteed level of performance are presented. We also consider discrete-time strategies in which the sampling time is

Dwell-Time Map

2014
This chapter focuses on the solution of the dwell-time map, which involves traditional convolution iteration and Fourier transform methods and the sub-aperture corrosion iteration method. Four compensation models for the implementation errors of the dwell-time map are also investigated to further improve fabrication efficiency.
