Park Model (Park, 1987). This model is widely used in practical calculations because of its simplicity. According to the model, the dissociation rate coefficient can be found by... 

The factor 5 is a fitting parameter of the Park model, which is recommended to be taken as 5 = 0.7. In initial publications, the effective temperature was taken approximately as Teff = V oTv. The Macheret-Fridman model permits the Park parameter to be found theoretically ...

Constitutive Law for Concrete Parts (Based on the Kent-Park Model)... 

The proposed constitutive law modeling the concrete in monotonic compression for the cases of confined and unconfined concrete is the Kent-Park model as described in Park and Paulay (1975). As it is shown in Fig. 4, the material follows a parabolic stress-strain curve up to a maximum stress equal to the cylinder s strength, after which it decays linearly with strain until the residual strength is reached. In tension, the model assumes a linear stress—strain behavior up until the tensile limit of the material is reached, and then the stiffness and strength decays with increasing strain (Fig. 5).

Concrete slab in compression can be modeled using stress-strain relationships proposed in EC2 or any of the stress-strain relationships presented in sections Constitutive Law for Concrete Parts (Based on the Kent-Park Model) and Constitutive Law for Concrete (Based on the Popovics-Saenz Law) for both unconfined (concrete above reinforcement level) and confined (concrete below reinforcement level) conditions. A typical example of the stress-strain relationship that can be used in analysis is presented in Fig. 15a for both concrete... 

Parks model predicts that oxide surfaces of different orientations have the same I EPS. Yet, Nabavi et al. (1993) showed, for example, that the pKi and pK2 of nanometric-size particles of cerium oxide Ce02 are very different on the (100), (110) and (111) faces. On the hydroxylated (100) face, oxygens with a coordination number Z = 2 are found, which belong either to the ideal surface or to adsorbed OH groups. On the two other faces, three-fold coordinated oxygens exist on the ideal surfaces, while singly coordinated oxygens result from the on-top adsorption of an OH".

RGA Method for 2X2 Control Problems To illustrate the use of the RGA method, consider a control problem with two inputs and two outputs. The more general case of N X N control problems is considered elsewhere (McAvoy, Interaction Analysis, ISA, Research Triangle Park, North Carohna, 1983). As a starting point, it is assumed that a linear, steady-state process model is available.
