However, for strongly-coupled gratings if the absorption of medium cannot be ignored, the diffraction efficiency decreases with widening of reference beam.

In this paper,we study a strongly-coupled parabolic system with initial boundary values. Under the appropriate conditions,using some prior estimate's techniques of Hlder inequality,comparison principle of ODE,Gagliard-Nirenberg,Poincaré inequality,Gronwall inequality and imbedding Theorem,we obtain the global existence and uniform boundness of solutions.

Matrix coupled mode theory model of strongly-coupled multiwaveguide optical nonlinear directional couplers

Attention is drawn to the possibility of creation of the supercooled strongly-coupled (nonideal) plasma by an explosive ejection from spacecraft into vacuum.

Studying the Properties of Supercooled Strongly-Coupled Plasma Created by Artificial Injection into Space

In strongly-coupled models for motor enzyme function, such as the original Huxley (1957) model for muscle, ATP binding and subsequent hydrolysis are required for the detachment and reattachment of every force-producing cross-bridge.

Conditions for such transition are studied, and properties of the resulting strongly-coupled plasma(particularly, the effective concentration of free-charge carriers)are briefly outlined.

According to the behavior of the combined process of multicomponent molecular diffusion and Knudson diffusion in porous catalysts, a set of second order nonlinear ordinary differential equations describing the concentrationprofiles of reactants and products for a single reaction in an isothermal spherical catalyst has been developed in this paper. In these differential equations, the concentration gradients of different reaction components are strongly coupled together. By using shooting method to solve the...

According to the behavior of the combined process of multicomponent molecular diffusion and Knudson diffusion in porous catalysts, a set of second order nonlinear ordinary differential equations describing the concentrationprofiles of reactants and products for a single reaction in an isothermal spherical catalyst has been developed in this paper. In these differential equations, the concentration gradients of different reaction components are strongly coupled together. By using shooting method to solve the two-point boundary value problem posed by this set of equations, the concentration profile of each reaction component and the numerical solution of effectiveness factor can he obtained. Because of the differences between the effective diffusion coefficients of the reaction species, the relations between the changes of their compositions in catalyst no longer obey the stoichiometric relations of the reaction. When the intraparticle diffusion restriction is serious, in the catalyst it may appear a "dead zone", in which the concentrations of the reaction components are asymptotic to the equilibrium concentrations and the chemical reaction practically does not proceed. As the "dead zone" exists, applying this mathematical model and the solution procedure, the radius of "dead zone" and the effectiveness factor under this condition can be solved. The cylindrical sh.ape catalysts commonly used in industry are treated as spheres of equal specific external surface.

It has been known that the most satisfactory method of determining rate constants and activation parameters is a full steady-state line-shape fitting orer the temperature range where exchange effects can be observed. For weakly coupled systems undergoing exchange it is possible to compute theoretical ine shapes using modified Bloch equation, but strongly coupled systems require a full density matrix (DM) treatment. The aim of this paper is to show how-to calculate line-shapes using the DM method. The paper consists...

It has been known that the most satisfactory method of determining rate constants and activation parameters is a full steady-state line-shape fitting orer the temperature range where exchange effects can be observed. For weakly coupled systems undergoing exchange it is possible to compute theoretical ine shapes using modified Bloch equation, but strongly coupled systems require a full density matrix (DM) treatment. The aim of this paper is to show how-to calculate line-shapes using the DM method. The paper consists of the basic theory of DM and the applications of DM theory to NMR line-shape calculations of inter- and intra-molecular exchanging systems.

From the characteristics of velocity admittance, a method of identification of modal parameters is developed by way of smoothing the measurements of frequency response of velocity. Several numerical examples show that this method is able to obtain the modal parameters of discrete or continuous systems and can be applied to the damped system which cannot be diagonalised. Moreover, the separation of strongly coupled modes can well be considered in the presence of neighbouring damping ratios and for a very high...

From the characteristics of velocity admittance, a method of identification of modal parameters is developed by way of smoothing the measurements of frequency response of velocity. Several numerical examples show that this method is able to obtain the modal parameters of discrete or continuous systems and can be applied to the damped system which cannot be diagonalised. Moreover, the separation of strongly coupled modes can well be considered in the presence of neighbouring damping ratios and for a very high modal density, for exampleThe representation of velocity admittance in the complex plan is well restituted in the range of frequency studied.In this paper, the author introduces non-dimensional coefficients so that the method may be made to extend the range to over 20 KHz.
