متن کاملA review of roll-to-roll nanoimprint lithography
UNLABELLED Since its introduction in 1995, nanoimprint lithography has been demonstrated in many researches as a simple, low-cost, and high-throughput process for replicating micro- and nanoscale patterns. Due to its advantages, the nanoimprint lithography method has been rapidly developed over the years as a promising alternative to conventional nanolithography processes to fulfill the demands...
متن کاملDesign Parameter Analysis of a Roll-to-Roll Printing Machine
The stability of multi-input and multi-output web-tension systems is an important factor that is required for the roll-to-roll printing machines. This paper analyzes stability for design parameters of a web-tension system of a high-speed gravure printing machine. Analyzed parameters include moment of inertia of the passive dancer, viscous friction coefficient of the dancer system, distances fro...
متن کاملExtended Slow-Roll Conditions and Rapid-Roll Conditions
We derive slow-roll conditions for a scalar field which is non-minimally coupled with gravity in a consistent manner and express spectral indices of scalar/tensor perturbations in terms of the slow-roll parameters. The conformal invariance of the curvature perturbation is proved without linear approximations. Rapid-roll conditions are also derived, and the relation with the slow-roll conditions...
متن کاملDeath roll of the alligator: mechanics of twist feeding in water.
Crocodilians, including the alligator (Alligator mississippiensis), perform a spinning maneuver to subdue and dismember prey. The spinning maneuver, which is referred to as the ;death roll', involves rapid rotation about the longitudinal axis of the body. High-speed videos were taken of juvenile alligators (mean length=0.29 m) performing death rolls in water after biting onto a pliable target. ...
