An example of unipolar induction is a slab of material with (relative) permittivity and (relative) permeability μ that is immersed in a uniform external magnetic field H0 parallel to the plane of the slab, such that if the slab has velocity v perpendicular to H0 but also in the plane of the slab, a nonzero voltage difference V is detected between sliding contacts (fixed in the laboratory) on op...

We present a method for  the construction of compactlysupported $left (begin{array}{lll}1 & 0 & -1\1 & 1 & 0 \1 &  0 & 1\end{array}right )$-wavelets  under a mild condition. Wavelets inherit thesymmetry of the corresponding scaling function and satisfies thevanishing moment condition originating in the symbols of the scalingfunction. As an application, an  example is  provided.

This paper presents a proof of Stirling's formula using Haar wavelets and some properties of Hilbert space, such as Parseval's identity. The present paper shows a connection between Haar wavelets and certain sequences.

We present a new kind of second generation wavelets on a rectangular grid. These wavelets are constructed using a 2D lifting scheme which is based on a red-black blocking scheme. Compared to classical tensor product wavelets on the same grid, these new wavelets show less anisotropy. The performance of the new wavelets is compared to tensor product wavelets in an image denoising application.

Our concern is with the construction of a frame in L 2 (S) consisting of smooth functions based on kernels of spherical harmonics. The corresponding decomposition and reconstruction algorithms utilize discrete spherical Fourier transforms. Numerical examples connrm the theoretical expectations. x1. Introduction Traditionally, wavelets were tailored to problems on the Euclidean space IR d. Howev...

In the present study, the heat of detonation of high energy compounds with CaHbNcOd  formula was obtained according to Kistiakowski-Wilson rules. Comparison of these results with experimental date, group additivity method and Kamlet method shows that the values of heat detonation based on the Kistiakowski-Wilson rules are more accurate. In the following, the values of detonation velocity and de...

We prove three results on wavelets for the Hardy space H (R). All wavelets constructed so far for H(R) are MSF wavelets. We construct a family of H-wavelets which are not MSF. An equivalence relation on H-wavelets is introduced and it is shown that the corresponding equivalence classes are non-empty. Finally, we construct a family of H-wavelets with Fourier transform discontinuous at the origin.

In the literature 2D (or bivariate) wavelets are usually constructed as a tensor product of 1D wavelets. Such wavelets are called separable. However, there are various applications, e.g. in image processing, for which non-separable 2D wavelets are preferable. In this paper, we investigate the class of compactly supported orthonormal 2D wavelets that was introduced by Belogay and Wang [2]. A cha...
