Iterative Learning Control for Trailing-Edge Flap Lift Enhancement with Pulsed Blowing

, 2015
A novel iterative learning control algorithm was developed and applied to an active flow control problem. The technique used pulsed air jets applied to a trailing-edge flap to enhance the lift. The iterative learning control algorithm used position-based

To lift or recut: Changing trends in LASIK enhancement

Journal of Cataract and Refractive Surgery, 2003
To report serious complications caused by recutting laser in situ keratomileusis (LASIK) flaps for enhancement and reconsider the current preferred method of LASIK enhancement.Multiple surgeon practices.This retrospective noncomparative nonconsecutive case series comprised LASIK patients in the private practices of 9 experienced refractive surgeons and

Image enhancement based on lifting wavelet transform

2009 4th International Conference on Computer Science & Education, 2009
The traditional image enhancement algorithms enhance noise signal in image while they enhance image, which leads to the de-scent of information entropy. Designing image enhancement systems with good nature is a goal which all researchers pursue. Method of lifting can best deal with MRA Multi-resolution Analysis method which is time and memory consuming

Enhancing Low Productivity Wells Using Special Gas Lift Design

Middle East Oil Show and Conference, 1999
Abstract Artificial lift using gas is considered the main source of life for most of Gupco's wells. Since employing gas lift technology in 1972, Gupco managed to improve total oil recovery and increase daily production rate in its operations.
