Fast evaluation of nonlinear functionals of tensor product wavelet expansions [PDF]
, 2010 For a nonlinear functional f, and a function u from the span of a set of tensor product interpolets, it is shown how to compute the interpolant of f (u) from the span of this set of tensor product interpolets in linear complexity, assuming that the index

The generalized sampling theorem for transforms of not necessarily square integrable functions
International Journal of Mathematics and Mathematical Sciences, Volume 8, Issue 2, Page 355-358, 1985., 1985 It is known that the generalized sampling theorem is valid for certain finite limit integral transforms of square integrable functions. In this note, we will extend the validity of the theorem to include transforms of absolutely integrable functions associated with differentiable kernels.

Quantum coherence of Gaussian states in curved spacetime
Results in Physics, 2019 We study quantum coherence of two-mode Gaussian states in the background of an asymptotically flat black hole. We find that quantum coherence between mode A observed by an inertial observer Alice and mode B observed by an accelerated Bob who hovers near ...

A HYPERBOLIC UNIFORM SPLINE METHOD FOR LINEAR FOURTH ORDER BOUNDARY VALUE PROBLEM
, 2013 In this paper, a numerical method is developed for solving a linear fourth order boundary value problem (4VBP ) by using the hyperbolic uniform spline of order 3 (lower order). There are both proved to be first-order convergent. Numerical results confirm

Closed balls for interpolating quasi-polynomials
, 2011 The classic interpolation problem asks for polynomials to fit a set of given data. In this paper, quasi-polynomials are considered as interpolating functions passing through a set of spatial points.

On bivariate fractal interpolation for countable data and associated nonlinear fractal operator
Demonstratio MathematicaFractal interpolation has been conventionally treated as a method to construct a univariate continuous function interpolating a given finite data set with the distinguishing property that the graph of the interpolating function is the attractor of a ...

A theoretical study on resistance of electrolytic solution: Measurement of electrolytic conductivity
Results in Physics, 2019 We propose a theoretical approach to determine the conductivity of electrolytic solution using sine waveform voltage as a triggering signal. The approach is based on the acquisition of the complex impedance in two-electrode conductance cell by analyzing ...
