Dual basicity equation

The electrochemical model allows, through the basic equation of the electrochemical kinetics (Eq. 13), the constraction and quantitative description of one actuator and several sensors working simultaneously in a physically uniform device. Such sensing polymeric motors do not exist in current human technologies only haptic muscles provide some parallel dual system. Human proprioception is based on haptic muscles, and artificial proprioceptive equations were attained Ifom Eq. 13 (Otero and Martinez 2015). [Pg.250]

Another dual-parameter equation has been introduced by Kamlet, Taft et al. [182] for correlating Lewis basicity ... [Pg.52]

Barrer (1984) suggested a further refinement of the dual-mode mobility model, including diffusive movements from the Henry s law mode to the Langmuir mode and the reverse then four kinds of diffusion steps are basically possible. Barrer derived the flux expression based on the gradients of concentration for each kind of diffusion step. This leads to rather complicated equations, of which Sada (1987, 1988) proved that they describe the experimental results still better than the original dual-mode model. This, however, is not surprising, since two extra adaptable parameters are introduced. [Pg.687]

Of the three QM-FEP methods which will be outlined here the QM implementation of the dual topology method is the most similar to the techniques which are used with MM systems. However, as opposed to a dual-topology classical force field calculation in which the interactions are pairwise additive such that only a limited subset of terms needs to be recalculated, a QM method requires two full SCF calculations. This method is readily understood by considering basic FEP theory. In the equation below we give the basic master equations for the FEP method. [Pg.105]

The simplest treatments of convective systems are based on a diffusion layer approach. In this model, it is assumed that convection maintains the concentrations of all species uniform and equal to the bulk values beyond a certain distance from the electrode, 8. Within the layer 0 x < 5, no solution movement occurs, and mass transfer takes place by diffusion. Thus, the convection problem is converted to a diffusional one, in which the adjustable parameter 8 is introduced. This is basically the approach that was used in Chapter 1 to deal with the steady-state mass transport problem. However, it does not yield equations that show how currents are related to flow rates, rotation rates, solution viscosity, and electrode dimensions. Nor can it be employed for dual-electrode techniques or for predicting relative mass-transfer rates of different substances. A more rigorous approach begins with the convective-diffusion equation and the velocity profiles in the solution. They are solved either analytically or, more frequently, numerically. In most cases, only the steady-state solution is desired. [Pg.332]

At relatively low pressures, what dimensionless differential equations must be solved to generate basic information for the effectiveness factor vs. the intrapellet Damkohler number when an isothermal irreversible chemical reaction occurs within the internal pores of flat slab catalysts. Single-site adsorption is reasonable for each component, and dual-site reaction on the catalytic surface is the rate-limiting step for A -h B C -h D. Use the molar density of reactant A near the external surface of the catalytic particles as a characteristic quantity to make all of the molar densities dimensionless. Be sure to define the intrapellet Damkohler number. Include all the boundary conditions required to obtain a unique solution to these ordinary differential equations. [Pg.506]

The solution operator describes how a function of the phase variables is mapped forward in time under the flow of the differential equation. An alternative ( dual ) perspective is in terms of the evolution of the measure (or density) of points in phase space. We begin by summarizing a few basic principles needed to provide a foundation for working with probability measures. [Pg.182]

The basic element of SL simulation is its dual-grid approach. The traditional static (Eulerian) grid is used to specify petrophysical properties, well locations and rates, and initial conditions, and to solve for the spatial pressure distributions using an implicit pressure exphcit saturation (IMPES) formulation. The dynamic (Lagrangian) grid represented by the SLs, on the other hand, is used to solve the hyperbohc equations that govern the transport of chemical species. [Pg.275]

The parallel between operator and vector spaces, used above, depends only on the existence of a scalar product. The metric defined in (13.5.8) is not the only possible choice (see e.g. Lowdin 1982, 1985), but it is the one most commonly employed in propagator theory. The same matrix notation applies to both vector and operator spaces, provided that the basic conventions are carefully observed i and i (playing the part of basis elements and their duals) are always of row and column form respectively, and all equations are then internally consistent. [Pg.469]

We now turn our attention to the dual formulation of kriging which leads us to linear equations of the same type as those that arise from interpolation with radial basic functions such as thin plate splines. Some of the basic ideas can be found in [4]. The first studies go back to [8],... [Pg.405]
