Inversion method for initial tsunami waveform reconstruction [PDF]
This paper deals with the application of the r-solution method to recover the initial tsunami waveform in a tsunami source area by remote water-level measurements. Wave propagation is considered within the scope of a linear shallow-water theory.

Randomized Dynamic Mode Decomposition
This paper presents a randomized algorithm for computing the near-optimal low-rank dynamic mode decomposition (DMD). Randomized algorithms are emerging techniques to compute low-rank matrix approximations at a fraction of the cost of deterministic ...

Due to the acoustic source distribution and limited bandwidth ultrasound measurement, the dominant ultrasound signals always come from the boundary of the electrical conductivity in magneto-acoustic tomography with magnetic induction (MAT-MI).

Approximate convolution using partitioned truncated singular value decomposition filtering for binaural rendering [PDF]
In conventional binaural rendering, a pair of head-related impulse responses (HRIR), measured from source direction to left and right ears, is convolved with a source signal to create the impression of a virtual 3D sound source when played on headphones.

Radio-frequency tomography was originally proposed to image underground cavities. Its flexible forward model can be used in free-space by choosing an appropriate dyadic Green's function and can be translated in the microwave domain. Experimental data are

Recursive POD expansion for the advection-diffusion-reaction equation [PDF]
This paper deals with the approximation of advection-diffusion-reaction equation solution by reduced order methods. We use the Recursive POD approximation for multivariate functions introduced in [M. AZAÏEZ, F. BEN BELGACEM, T. CHACÓN REBOLLO, Recursive

Receiver function analysis is perhaps the most popular tool amongst seismologists for estimating the receiver-side crustal structure using three-component recordings of teleseismic P-wave coda. Several methods have been suggested for successful construction of receiver function time series, and almost all of them involve deconvolution, the inverse of ...

Characterizing coherence with quantum observables
We introduce a procedure based on quantum expectation values of measurement observables to characterize quantum coherence. Our measure allows one to quantify coherence without having to perform tomography of the quantum state and can be directly ...

Polynomial basis conversion made stable by truncated singular value decomposition
The aim of this paper is to provide a numerically stable method for the transformation between the power and the Bernstein basis resp. the Bernstein and the B-spline basis. Although this transformation process is defined by a system of linear equations, the direct use of this linear system is sometimes not recommended, since it may be ill conditioned ...
