Co-pyrolysis of tobacco stalk (TS) with different types of polymer wastes such as scrap tire (ST), polypropylene (PP) and polyvinyl chloride (PVC) was investigated. Thermogravimetric analyzer coupled with Fourier transform infrared spectrometer was …
Superregular breather solution that develops from a small localized perturbation based on the higher-order generalized nonlinear Schrödinger equation.
We study a variable-coefficient nonlinear Schrodinger (vc-NLS) equation with higher-order effects. We show that the breather solution can be converted into four types of nonlinear waves on constant backgrounds including the multipeak solitons, …
We study the nonlinear waves on constant backgrounds of the higher-order generalized nonlinear Schrodinger (HGNLS) equation describing the propagation of ultrashort optical pulse in optical fibers. We derive the breather, rogue wave, and semirational …
