Crossover point

If TI T2, with both values less than unity, the copolymer starts out richer in monomer 1 than the feed mixture and then crosses the 45° line, and is richer in component 2 beyond this crossover point. At the crossover point the copolymer and feed mixture have the same composition. The monomer ratio at this point is conveniently solved from Eq. (7,15) ... 

Figure 2 Genetic operators used to create a population of children chromosomes from a population of parent chromosomes, (a) Single-point mutation. A gene to he mutated is selected at random, and its value is modified, (b) One-point crossover. The crossover point is selected randomly, and the genes are exchanged between the two parents. Two children are created, each having genes from both parents.

For this computer system, the crossover point where direct SCF beats the conventional algorithm happens at around 120 basis functions ( N=7). This level may be lower for some vector processors. ... 

Simply speaking, the CPU may be spending most of its time waiting for data to be transferred from disk. Direct methods, on the other hand, use the CPU with a near 100% efficiency. For machines without fast disk transfer (like workstation type machines) the crossover point for direct vs. conventional methods in terms of wall clock time may be so low that direct methods are always preferred. 

Most large generator designs also incorporate a regenerative FW heating facility where from 20 to 30% of the throttle steam may be withdrawn from the turbine at various points to provide the necessary heating. In addition, the primary steam requirement for the FW pump turbines is extracted from the main turbine at the IP to LP crossover point. 

The crossover point for the O p jTC energy levels takes place just after N2, so the general diagram for Z < 7 in Figure 10-35 applies to all three molecules. The valence electron counts are B2 = 6 e, ... 

Figure 24. Plot of the particle-size distribution versus the transition temperature Tross, which describes the crossover point between an activated transport mechanism (ln(A) oc EJT and variable range hopping (VRH) (ln(R)ocT ). Note that Tdoss has a OK value at a finite (3%) particle-size distribution. (Reprinted with permission from Ref. [56], 2002, American Chemical Society.)...

We should find that for values of Xj > 0.5, the system stays stable. For = 0.5, the system may become unstable, but only at infinitely large Kc. The system may become unstable for x < 0.5 if Kc is too large. Finally, for the choice of x = 0.1, we should find with the MATLAB function riocf ind that the ultimate gain is roughly 0.25, the same answer from Example 7.3. How close you get depends on how accurate you can click the axis crossover point. 

If the crossover points Q (x) are determined from Fig. 45, taking the x-values at half-step height, Q (x) = 1/1 (x) = (0.7 + 0.2)x is obtained in the case of the PS system. This has to be compared with static value Qs (x) = 1.6x, derived from the same polymer solvent system by elastic neutron scattering [103], As long as no corresponding data from other polymer solvent systems are available, the final decision as to whether static and dynamic scaling lengths coincide or not, is still open. 

For PS/d-cyclohexane, the only system where comparable static and dynamic data from the crossover regime are available, the static and dynamic crossover points Q (x) = l/c/x) do not coincide... 

Q2 behavior takes place at decreasing Q. The position of the crossover point Q (c) is a direct measure of the dynamic correlation length (c) = 1/Q (c). The plateau value at low Q determines the collective diffusion coefficient Dc. A simultaneous fit of all low Q spectra where a simple exponential decay was found led to the concentration dependence and the numerical values of Dc... 

Response Yes, it certainly would be most interesting to investigate this question. This is closely related to the previous discussion concerning the relationship between noise and nonlinearity, so I would modify the statement of the problem to At what point does one or another effect dominate the behavior of the calibration that is, where is the crossover point Investigating questions of this sort is called research , and a more fundamental question arises why isn t anybody doing such investigations ... 

Fe2L2) and longer chain the monomeric (FeL) form. When the intermediate connecting chain is -(CH2)6- (39), a crossover point between Fe2L2 and FeL is reached where both are present (52).
