The Infrared Einstein Ring in the Gravitational Lens MG 1131+0456 and the Death of the Dusty Lens Hypothesis
We have obtained and modeled new NICMOS images of the lens system MG 1131+0456 , which show that its lens galaxy is an H= 18.6 mag, transparent, early-type galaxy at a redshift of zl ≃ 0.85; it has a major axis effective radius Re = 0. ′′68 ± 0. ′′05, projected axis ratio b/a = 0.77 ± 0.02, and major axis PA= 60 ± 2. The lens is the brightest member of a group of seven galaxies with similar R–I...
متن کاملIterative regularization method applied to reconstruction of 3D scattering geometry
The problem of the shape reconstruction of a scatterer from the scattered field measured outside under the illumination of an incident plane wave is considered. Theoretically, the inversion algorithm is derived using integral equation formulations together with the Newton Kantorovich iterative regularization technique. Numerical results show that the good reconstruction is obtained with the onl...
متن کاملCT Metal Artifact Reduction in the Spine: Can an Iterative Reconstruction Technique Improve Visualization?
BACKGROUND AND PURPOSE Metal-related artifacts from spine instrumentation can obscure relevant anatomy and pathology. We evaluated the ability of CT images reconstructed with and without iterative metal artifact reduction to visualize critical anatomic structures in postoperative spines and assessed the potential for implementation into clinical practice. MATERIALS AND METHODS We archived CT ...
متن کاملIterative Learning Control Applied to Batch Processes: an Overview
With the recent emphasis on batch processing by the emerging industries like the microelectronics and biotechnology, the interest in batch process control has been renewed. In this paper, we present an overview of the Iterative Learning Control (ILC) technique, which can be used to improve tracking control performance in batch processes. We present the fundamental concepts and review the variou...
