Peregrine soliton as a limiting behavior of the Kuznetsov-Ma and Akhmediev breathers
N. Karjanto
This article discusses a limiting behavior of breather solutions of the focusing nonlinear Schrödinger (NLS) equation. These breathers belong to the families of solitons on a non-v…
Challenges in teaching Real Analysis classes at the University of PGRI, South Sumatra, Indonesia
E. Septiati, N. Karjanto
This paper discusses our experiences and challenges in teaching advanced undergraduate Real Analysis classes for Mathematics Education students at the University of PGRI (Persatuan…
The effects of increasing speed on the structure of axle box bogies of NT-11 trains
S. W. Rienstra, N. Karjanto, S. D. Destiyani +1
The occurrence of cracks on the structure of axle box bogie of NT-11 economic trains operated by PT Kereta Api Indonesia is studied. These axle box bogies were designed for the max…
A theoretical study on a two-dimensional flap-type wavemaker
N. Karjanto
A mathematical model for unidirectional wave generation explained in this study. The model consists of Laplace's equation in the semi-infinite two-dimensional water interior, dynam…
The nonlinear Schrödinger equation: A mathematical model with its wide-ranging applications
N. Karjanto
The nonlinear Schrödinger equation (NLSE) models the slowly varying envelope dynamics of a weakly nonlinear quasi-monochromatic wave packet in dispersive media. In the context of B…
Exploiting bifurcations in waveguide arrays for light detectors
N. Karjanto, H. Susanto
An array of a finite number waveguides, driven laterally by injecting light at the outer waveguides, is considered. The array is modeled by a discrete nonlinear Schrödinger equatio…
