Pemodelan Tsunami Sederhana dengan Menggunakan Persamaan Differensial Parsial

Indonesian Journal of Applied Physics, 2018
One way to solve fluid dynamics problem is using partial differential equation. By using Taylor expansion, fluid dynamics can be applied simply. For the example is tsunami wave.

Evaluation of the performance of fractional evolution equations based on fractional operators and sensitivity assessment

Results in Physics, 2023
In this article, the nonlinear fractional Kudryashov’s equation and the space–time fractional nonlinear Tzitzeica–Dodd–Bullough (TDB) equation are solved using the new auxiliary equation method, which yields innovative analytical solutions using β and M ...

Different forms of optical soliton solutions to the Kudryashov’s quintuple self-phase modulation with dual-form of generalized nonlocal nonlinearity

Results in Physics, 2023
In this paper, the exact soliton solutions and other exact solutions for nonlinear Schrodinger’s equation having Kudryashov’s quintuple power law of refractive index together with dual form of generalized nonlocal nonlinearity are studied.

One-way acoustic beam splitting in spatial four-waveguide couplers designed by adiabatic passage

New Journal of Physics, 2023
In this work, we introduce quantum-mechanical adiabatic passage into the design of spatial acoustic four-waveguide (WG) couplers. Thanks to the agreement in form between the Schrödinger equation in quantum mechanics and the coupled-mode equation of ...

Propagator and wave-equation inversion for near-receiver material properties [PDF]

, 2004
Near-receiver material properties are required for the separation of the recorded wavefield into upgoing and downgoing P and S waves, and are also important for static time-shift corrections.

Scattering of relativistic spinless particles within the Feshbach-Villars formalism

Heliyon, 2022
We consider the relativistic quantum scattering of spinless particles in one-spatial dimension using the Feshbach-Villars formalism. We construct the general form of the scattering matrix, for symmetric and non-symmetric potentials, based on the symmetry

Wave-equation Qs Inversion of Skeletonized Surface Waves

, 2017
We present a skeletonized inversion method that inverts surface-wave data for the Qs quality factor. Similar to the inversion of dispersion curves for the S-wave velocity model, the complicated surface-wave arrivals are skeletonized as simpler data ...

Lack of controllability of the heat equation with memory [PDF]

, 2012
We consider a model for the heat equation with memory, which has infinite propagation speed, like the standard heat equation. We prove that, in spite of this, for every T > 0 there exist square integrable initial data which cannot be steered to hit zero ...

New solitary wave in shallow water, plasma and ion acoustic plasma via the GZK-BBM equation and the RLW equation

Propulsion and Power Research, 2017
This work obtains the disguise version of exact solitary wave solutions of the generalized (2+1)-dimensional Zakharov-Kuznetsov–Benjamin-Bona-Mahony and the regularized long wave equation with some free parameters via modified simple equation method (MSE)
