In this paper, we address the problem of boundary controllability for one-dimensional nonlinear shallow water system, describing free surface flow as well under a fixed gate structure. The system differential equations considered can be interpreted simplified model particular type wave energy device converter called oscillating column. physical requirements naturally lead to exact in prescribed...

investigations were carried out on coal tailings by conventional cell and column flotation techniques. tests were conducted to assess processing coal tailings of alborz markazi coal washing plant in iran by column flotation. the effects of reagent type/dosage were investigated with conventional flotation and their results were used in the performance of column flotation. also the effects of the...

In a plasma wakefield accelerator in the nonlinear regime the accelerated bunch electrons oscillate in a pure ion column. They emit strong synchrotron, also known as betatron radiation, in the keV to MeV photon range [1]. In previous experiments with a single electron bunch the oscillating electrons where distributed symmetrically about the beam axis or the ion column axis. However, with a driv...

oscillating reactions are one of the most interesting topics in chemistry and analytical chemistry. fluctuations in concentrations of one the reacting species (usually a reaction intermediate) create an oscillating chemical reaction. in oscillating systems, the reaction is far from thermodynamic equilibrium. in these systems, at least one autocatalytic step is required. developing an instinctiv...

This work presents a two-dimensional numerical analysis of wave channel and oscillating water column (OWC) device. The main goal is to validate methodology which uses transient velocity data as means impose boundary condition for the generation waves. To achieve this, was simulated using regular waves with same parameters those used in laboratory experiment. First, these were imposed prescribed...

The classical theory of locomotion in sharks proposes that shark pectoral fins are oriented to generate lift forces that balance the moment produced by the oscillating heterocercal tail. Accordingly, previous studies of shark locomotion have used fixed-wing aircraft as a model assuming that sharks have similar stability and control mechanisms. However, unlike airplanes, sharks are propelled by ...

The Robinson-Schensted-Knuth correspondence (RSK, see [8] and Corollary 2.5 below) is a bijection between pairs of semi-standard Young tableaux of the same shape and matrices with nonnegative integer entries with prescribed column and row sums. This correspondence plays an important role in the representation theory of the symmetric group and general linear groups, and in the theory of symmetri...
