We present some features of Kerr black hole horizons that are replicated on orbits accessible to outside observers. use the concepts horizon confinement and replicas show outer there exist photon whose frequencies contain information about inner can, in principle, be detected through emission spectra holes. It is shown such close rotation axis geometry. argue these results could used recognize ...

Rats trained to relocate a particular corner in a rectangular arena systematically confound the correct corner and the diametrically opposite one--this rotational error demonstrates the use of the geometry of space (i.e., the spatial arrangement of the different components of a visual scene). In many cases, geometric information is preferentially used over other spatial cues, suggesting the pre...

In this paper we introduce an efficient hole-filling strategy for 3D meshes and at the same time aesthetically recover the sharp features of the original 3D model at the hole areas. Commonly, hole filling techniques try to fill up the hole first then smooth it. Very few have tried to recover the fine features of the original model at the holes. Our hole filling technique is different from other...

Application of stochastic geometry methods to pattern recognition is analyzed. The paper is based on Trace-transformations of original images introduced in [1] into images on the Mobius band. Trace–transformation is a new geometrical transformation, which is connected with image scanning on complex trajectories, including random parameters trajectories. Based on this new geometric transformatio...

We present an in-depth examination of the effectiveness of radial basis function kernel (beyond Gaussian) estimators based on orthogonal random feature maps. We show that orthogonal estimators outperform state-of-the-art mechanisms that use iid sampling under weak conditions for tails of the associated Fourier distributions. We prove that for the case of many dimensions, the superiority of the ...

We study some aspects of type 0 strings propagating in the two dimensional black hole geometry, corresponding to the exact SL(2)/U (1) SCFT background.

Effective global manufacturing enterprises require internet-based tools and technologies to virtually integrate the efforts of customers, designers, and manufacturers who work in separate office buildings or on separate continents. We present the framework for an internetaccessible, feature-based, CNC programming environment. The environment empowers users from different geographical sites to c...

Any cold, optically-thick matter in the vicinity of an accreting black hole, such as the accretion disk, can intercept and reprocess some fraction of the hard X-ray continuum emission, thereby imprinting atomic features into the observed spectrum. This process of ‘X-ray reflection’ primarily gives rise to a broad reflection ‘hump’ peaking at ∼ 30 keV and an iron emission line at 6.4 keV. In thi...

The standard approach to initial data for both analytic and numerical computations of black hole collisions has been to use conformally-flat initial geometry. Among other advantages, this choice allows the simple superposition of holes with arbitrary mass, location and spin. The conformally flat restriction, however, is inappropriate to the study of Kerr holes, for which the standard constant-t...

We present detailed calculations of the quasinormal modes of ReissnerNordström black holes. While the first few, slowly damped, modes depend on the charge of the black hole in a relatively simple way, we find that the rapidly damped modes show several peculiar features. The higher modes generally spiral into the value for the extreme black hole as the charge increases. We also discuss the possi...
