A fast algorithm for approximating the ground state energy on a quantum computer
, 2013 Estimating the ground state energy of a multiparticle system with relative error $\e$ using deterministic classical algorithms has cost that grows exponentially with the number of particles.

Bell wavelets method to solve class of fractional differential equations arising in fluid mechanics
Partial Differential Equations in Applied MathematicsThis study introduces a new Bell wavelet matrix method to solve a class of fractional differential equations arising in fluid mechanics. The class under consideration comprises the fractional relaxation-oscillation equation (R-OE) as a special case.

Enhanced curve representations using piecewise non-linear binary subdivision scheme
Arab Journal of Basic and Applied SciencesThis study presents a piecewise non-linear binary subdivision scheme based on a four-point linear binary subdivision scheme. This scheme is first transformed into a piecewise linear subdivision scheme and then into a piecewise non-linear subdivision ...

Shape preserving $C^2$ interpolatory subdivision schemes [PDF]
, 1998 Stationary interpolatory subdivision schemes which preserve shape properties such as convexity or monotonicity are constructed. The schemes are rational in the data and generate limit functions that are at least $C^2$.

Hermite subdivision schemes, exponential polynomial generation, and annihilators [PDF]
, 2013 We consider the question when the so--called spectral condition} for Hermite subdivision schemes extends to spaces generated by polynomials and exponential functions.

Complete Algebraic Reconstruction of Piecewise-Smooth Functions from Fourier Data [PDF]
, 2014 In this paper we provide a reconstruction algorithm for piecewise-smooth functions with a-priori known smoothness and number of discontinuities, from their Fourier coefficients, posessing the maximal possible asymptotic rate of convergence -- including ...
