Real-Time Detection Method for Center and Attitude Precise Positioning of Cross Laser-Pattern

open access: yesApplied Sciences, 2021
Optical metrology has experienced a fast development in recent years—cross laser-pattern has become a common cooperative measuring marker in optical metrology equipment, such as infrared imaging equipment or visual 3D measurement system.

Variable metric inexact line-search based methods for nonsmooth optimization [PDF]

open access: yes, 2015
We develop a new proximal-gradient method for minimizing the sum of a differentiable, possibly nonconvex, function plus a convex, possibly non differentiable, function.

Search and Discovery Tools for Astronomical On-line Resources and Services [PDF]

open access: yes, 2000
A growing number of astronomical resources and data or information services are made available through the Internet. However valuable information is frequently hidden in a deluge of non-pertinent or non up-to-date documents.

A Parallel Best-Response Algorithm with Exact Line Search for Nonconvex Sparsity-Regularized Rank Minimization [PDF]

open access: yes, 2017
In this paper, we propose a convergent parallel best-response algorithm with the exact line search for the nondifferentiable nonconvex sparsity-regularized rank minimization problem.

On-line learning from search failures [PDF]

open access: yesMachine Learning, 1994
Learning by explaining failures and avoiding similar ones thereafter is an attractive way to speed up problem solving. However, previous methods for explanation-based learning from failure can take too long to detect failures, explain them, or test the learned rules.

Levenberg-Marquardt and Line-Search Extended Kalman Smoothers

open access: yesIEEE International Conference on Acoustics, Speech, and Signal Processing, 2020
The aim of this article is to present Levenberg-Marquardt and line-search extensions of the classical iterated extended Kalman smoother (IEKS) which has previously been shown to be equivalent to the Gauss-Newton method.

A New Forward–Backward Algorithm with Line Searchand Inertial Techniques for Convex Minimization Problems with Applications

open access: yesMathematics, 2021
For the past few decades, various algorithms have been proposed to solve convex minimization problems in the form of the sum of two lower semicontinuous and convex functions.

The contribution of AGN to the X-ray background: the effect of iron features [PDF]

open access: yes, 1999
The contribution of the iron emission line, commonly detected in the X-ray spectra of Seyfert (Sey) galaxies, to the cosmic X-ray background (XRB) spectrum is evaluated in the framework of the XRB synthesis models based on AGN unification schemes.

Searching for Emission-Line Galaxies [PDF]

open access: yesInternational Astronomical Union Colloquium, 1984
Survey methods for finding emission-line galaxies are reviewed. Observational selection effects are investigated by comparing different surveys and the limitations of the different techniques are discussed. The advantages of Ha surveys for finding low luminosity galaxies and those with low excitation emission spectra are emphasized.
