The higher-order nonlinear Schrödinger equation with combined nonlinearities is derived by an asymptotic reduction from the (2+4) Korteweg?de Vries model for weakly nonlinear wave packets for the context of interfacial waves in a three-layer symmetric me...

An algorithm is presented for the construction of an asymptotic approximation of a stable stationary solution to a diffusion equation system in a two-dimensional domain with a smooth boundary and a source function that is discontinuous along some smooth ...

The presence of a number of space debris in low Earth orbits poses a serious threat for current spacecraft operations and future space missions. To mitigate this critical problem, international guidelines suggest that an artificial satellite should decay...

This note provides a neat and enjoyable expansion and application of the magnificent Ordentlich-Cover theory of ?universal portfolios?. I generalize Cover?s benchmark of the best constant-rebalanced portfolio (or 1-linear trading strategy) in hindsight b...

In this paper, we take into account a two-dimensional inverse scattering problem for localizing small electromagnetic anomalies when they are surrounded by small, randomly distributed electromagnetic scatterers. Generally, subspace migration is considere...

A substantial issue in modern risk management is the measurement of risks. Specify, the requirement to quantify risk discovers in many different contexts. For instance, a regulator measures the risk exposure of a government institution in order determini...

This paper proposes the study of the application of fuzzy logic on the relevant parameter of biomass pyrolysis. The frequency factor, the upper limit of ?dE?, and the scale and shape parameters of the fuzzy Gamma distribution were fuzzified in order to e...
