A well-balanced adaptive Haar wavelet finite volume scheme for 1D free surface water flows

Ain Shams Engineering Journal, 2019
This paper studies a Haar-wavelet based finite volume method in terms of its capability of preserving a well-balanced property compared to the classical finite volume method, as well as with its application on the real case of the shallow water flow ...

Haar-LikeWavelets over Tetrahedra

Journal of Computer Science and Technology, 2017
In this paper we define a Haar-like wavelets basis that form a basis for L2(T,S,μ), μ being the Lebesgue measure and S the σ -algebra of all tetrahedra generated from a subdivision method of the T tetrahedron.

Quantum Sensing of Fast Time-Varying Magnetic Field With Daubechies Wavelets

IEEE Access
The waveform of the time-varying magnetic field can be reconstructed by combining the use of quantum sensing technology and orthogonal functions, such as Walsh and Haar wavelet functions, as the control sequences of qubits.

Haar wavelets based technique in evolution problems

, 2004
The compression property of wavelets in the analysis of an evolution problem (with unsmooth initial conditions) is investigated. The effectiveness of wavelets both in the reduction of complexity (number of coefficients) and in better approximation is ...

Free Vibration Analysis of Non-Uniform Timoshenko Beams Using Haar Wavelets [PDF]

In this paper, we present a method using Haar wavelets for solving axially functionally graded (FG) Timoshenko beam equations with non-uniform cross-sections. We compare two different approaches to the solution.
