Three dimensional spacelike warped anti-de Sitter space is studied in the context of Einstein theories of gravity and string theory, where there is no gravitational Chern-Simons term in the action. We propose that it is holographically dual to a two-dimensional conformal field theory with equal left and right moving central charges. Various checks of the central charges are offered, based on th...

This article proposes and studies warped-linear models for time series classification. The proposed models are time-warp invariant analogues of linear models. Their construction is in line with time series averaging and extensions of k-means and learning vector quantization to dynamic time warping (DTW) spaces. The main theoretical result is that warped-linear models correspond to polyhedral cl...

We present a statistical study of optical warps in a sample of 540 galaxies, about five times larger than previous samples. About 40% of all late-type galaxies reveal S-shaped warping of their planes in the outer parts. Given the geometrical parameters and detection sensitivity, this result suggests that at least half of all galaxy disks might be warped. We demonstrate through geometrical simul...

— In this paper, the design of a computationally efficient variable bandpass digital filter is presented. The center frequency and bandwidth of this filter can be changed online without updating the filter coefficients. The warped filters, obtained by replacing each unit delay of a digital filter with an allpass filter, are widely used for various audio processing applications. However, warped ...

The HI gas in the outer regions of spiral galaxies commonly rises above and below the inner galactic plane in characteristic `integral sign' warps. Such bending distortions were rst observed nearly 40 years ago in our own galaxy (Burke 1957, Kerr 1957; see Burton 1988 for a review), and since then the nature and excitation of warped discs has been a major unsolved problem in galactic dynamics (...

We obtain a basic inequality involving the Laplacian of the warping function and the squared mean curvature of any warped product isometrically immersed in a Riemannian manifold (cf. Theorem 2.2). Applying this general theory, we obtain basic inequalities involving the Laplacian of the warping function and the squared mean curvature of C-totally real warped product submanifolds of (κ, μ)-space ...

The scattering amplitude for the longitudinal weak bosons is investigated in the SU(3) gauge-Higgs unification as a function of the scattering energy, the Wilson line phase θH and the warp factor. The θH-dependence of the amplitude is quite different in the flat and the warped spacetimes. Generically the amplitude is enhanced for θH = O(1) in the warped case while it is almost independent of θH...

In this paper we consider contact CR-warped product submanifolds of the type $M = N_Ttimes_f N_perp$, of a nearly Kenmotsu generalized Sasakian space form $bar M(f_1‎, ‎f_2‎, ‎f_3)$ and by use of Hopf's Lemma we show that $M$ is simply contact CR-product under certain condition‎. ‎Finally‎, ‎we establish a sharp inequality for squared norm of the second fundamental form and equality case is dis...

I investigate a new approach for determining the pre-warp homography required to correct a projector image for perspective when projecting on a single flat surface. By using a depth camera placed at a fixed transform near the projector, the normal of the surface can be predicted in real time. By updating a homography on the image to be projected based on the projector intrinsics and the surface...
