We study two members of the multi-component AKNS hierarchy. These are multi-NLS and multi-MKdV systems. derive Hirota bilinear forms these equations obtain soliton solutions. find all possible local nonlocal reductions systems give a prescription to their also (2+1)-dimensional extensions

The main focus of the present article is the development of a general solution framework for coupled and/or interaction multi-physics problems based upon re-using existing codes into software products. In particular, we discuss how to build this software tool for the case of fluid-structure interaction problem, from finite element code FEAP for structural and finite volume code OpenFOAM for flu...

In this paper, a frequency reconfigurable multiple-input-multiple-output (MIMO) antenna has been described. The idea of the design is to form reconfigurable MIMO antenna by the development of two-port antenna that are identical to each other and pin diodes are used to achieve the frequency reconfigurability. The design of the canonical element consists of compact folded slots with one pin diode...

In this contribution, a single-node multi-GPU thermal lattice Boltzmann solver is presented. The program is based on the TheLMA framework which was developed for the purpose. The chosen implementation and optimisation strategies are described, both for inter-GPU communication and for coupling with the thermal component of the model. Validation and performance results are provided as well.

heavy metals such as cu(ii) and pb(ii) are among the hazardous pollutants that lead to severe ecological problems and have a toxic effect on living organisms. the removal of cu(ii) and pb(ii) by iranian bentonite experiment were conducted in single component and multi component systems. the bentonite from the birjand area was characterized by x-ray diffraction pattern and ftir spectroscopy. the...

Under the frame of the (2+1)-dimensional zero curvature equation and Tu model, the (2+1)-dimensional dispersive long wave hierarchy is obtained. Furthermore, the loop algebra is expanded into a larger one. Moreover, a class of integrable coupling system for dispersive long wave hierarchy and (2+1)-dimensional multi-component integrable system will be investigated.

A palladium-catalyzed three-component reaction of bis-(2-iodoaryl)carbodiimide, isocyanide, and amine gives rise to quinazolino[3,2-a]quinazolines and related compounds in good yields. Multi-bonds are formed in one pot through nucleophilic attack, isocyanide insertion, and C-N coupling during the reaction process.

1. Abstract This paper combines efficient uncertainty propagation and sampling techniques for uncertainty quantification of aerospace structures. A new method is developed for including uncertainty quantification in multi-disciplinary system analysis (MDA) that usually requires iterative analyses with a large number of coupling variables. The methodology for MDA estimates the probability distri...
