Visual primitives have long been proposed, under the name of geons or generalized cylinders, as components for object models in the brain and in the computer. Geons constitute a structural level intermediate between features and whole objects, and can form a basis for powerful generalization between different view points. We here present a system for the extraction of geon models from images of...

The nature of the obscuring material in active galactic nuclei is still uncertain. Although some sources, such as Cygnus A, show evidence for a geometrically thick “torus” as originally suggested, recent work on the radiation-driven warping instability discovered by Pringle suggests that obscuration by thin, warped disks may play a crucial role in AGN.

A careful analysis of the gravitational geon solution found by Brill and Hartle is made. The gravitational wave expansion they used is shown to be consistent and to result in a gauge invariant wave equation. It also results in a gauge invariant effective stress-energy tensor for the gravitational waves provided that a generalized definition of a gauge transformation is used. To leading order th...

We report the results of our CO J = 4 ! 3 line and rest frame 650 m continuum observations of the z=0.93 hyperluminous infrared galaxy FSC 15307+3252 using the Owens Valley Millimeter Array. No line or continuum emission was detected, but the derived limits provide a useful constraint on the temperature, emissivity, and mass of the cold dust associated with FSC 15307+3252 and its molecular gas ...

Resumen— This paper analyzes the robustness of the king networks for fault tolerance. To this aim, a performance evaluation of two well known fault tolerant routing algorithms in king as well as 2d networks is done. Immunet that uses two virtual channels and Immucube, that has a better performance while requiring three virtual channels. Experimental results confirm the excellent behavior, both ...

mohammad akram (ghanimat-e-konjahi) was from gujarat, india and lived during the era of alamgir king (eleventh and twelfth centuries). in his poetry, one can find new ideas and delicate senses especially in his neirang-e-eshgh, which is also known as ghanimat. his complete collection of poetry consists of lyrics, elegies and quatrains. in his poetry, ghanimat has followed great masters of poetr...

New methods are presented for increasing the bandwidth of wire antennas using impedance loading. This paper extends the seminal Wu-King theory of the internal impedance profile that produces travelling-wave only current modes on a center-fed dipole antenna. It also presents a numerical optimization methodology based on Central Force Optimization, a new deterministic multidimensional search and ...
