At given values of the parameters, there are optimal values of the micro-channel diameter and length, which correspond to a maximum efficiency coefficient. [Pg.423]

The multiplier tells how the optimal value of the objective func tion changes for this small change in the value of a constraint while holding all the other constraints at zero. It is for this reason that they are often called shadow prices. [Pg.484]

Concerning the VDW parameters, the ability to directly apply previously optimized values makes convergence criteria unnecessary. If VDW parameter optimization is performed based on pure solvent or crystal simulations, then the heats of vaporization or sublimation should be within 2% of experimental values, and the calculated molecular or unit cell volumes should be also. If rare gas-model compound data are used, the references cited above should be referred to for a discussion of the convergence criteria. [Pg.33]

The design of the heat exchanger network is greatly simplified if the design is initialized with an optimized value for [Pg.233]

The standard requires plant layouts to minimize material travel and handling, synchronize material flow, and optimize value added use of floor space and to use a multidisciplinary approach for developing plant facility and equipment plans. [Pg.212]

Although the even tempered function scheme is fairly reasonable far from the nucleus, each function added is slightly further from the energy-optimized value. Generally, two or three additional functions at the most will be added to a basis set. Beyond this point, it is most elficient to switch to a different, larger basis. [Pg.236]

Note The sample job files for this chapter do not generally include the optimization step. The molecule specifications in these input files have already been set to their optimized values. [Pg.63]

As p ) of the optimization procedure, we will have to determine which iKxles shouiu oe intercepted and the optimal values of die intercepted nodes. Next, let us consider the case when only one node is intercepted at a time. [Pg.169]

No attempt should be made to optimize pressure, reflux ratio, or feed condition of distillation in the early stages of design. The optimal values almost certainly will change later once heat integration with the overall process is considered. [Pg.92]

A finite difference formula is used to estimate the second derivatives of the coordinate vector with respect to time and S is now a function of all the intermediate coordinate sets. An optimal value of S can be found by a direct minimization, by multi-grid techniques, or by an annealing protocol [7]. We employed in the optimization analytical derivatives of S with respect to all the Xj-s. [Pg.270]

Once creation of the PV A database is complete, optimized probabilities may be calculated for the experimental spectrum at hand. Since the iterative procedure is restricted to a 2048 data point region, zoom cursors are displayed and set by the user until this condition is satisfied. In this case, the methylene region was selected and an initial guess for the Bernoullian probability (Pr=0.5) and linewidth (13.0Hz) were given. Optimized values for the probability and linewidth were Pr=0.52 and 12.8Hz, respectively. [Pg.166]

A certain subset of the raw or adjusted measurements is used to adjust the parameter estimate. Once the optimal values are attained, the model is used to predict values to compare against other measurement sets or subsets. These additional measurements provide an independent check on the parameter estimates and the model vahdity. [Pg.2575]

The effect of various parameters on the efficiency coefficient is illustrated in Fig. 10.15a-d. It may be seen, that an increase of heat flux on the wall leads to a significant decrease in 17. It is due to the meniscus displacement towards the inlet and growth of heat losses into the cooling liquid. The calculations show (Fig. 10.15a-c) that for given values of parameters there is some optimal value of a micro-channel s diameter and length, at which the coefficient of efficiency reaches maximum.

All the nmr measurements were made in the temperature range 6—7 K to ensure complete rigidity of the structure and in the case of the strained (1-form, no opportunity for relaxation to occur. The results are shown in Fig. 12, and indicate a very clear difference between the anisotropy for the strained and relaxed structures. Detailed consideration of the results for the p-form showed that only those models proposed by Hall and Pass32) termed by them Models 6 and 7, and the model of Yokouchi et al.34) need be further analysed. (These models are shown in Fig. 13). In fact, the second moment anisotropy could only be modelled accurately by the Hall and Passmodel 7, as can be seen from the results shown in Fig, 14. These fits were obtained by taking optimal values for P2, P4 and the crystallinity. It was assumed that the major contribu- [Pg.111]
