Asymptotic load

This paper will describe (1) the load to strain relationships of the tissue during confined and unconflned compression against platens of different porosity (2) their strain rate dependency (3) some aspects of the tissue s load-dissipation characteristics and (4) the time invariant or asymptotic load to strain relationship of cartilage following relaxation.

With a favorable isotherm and a mass-transfer resistance or axial dispersion, a transition approaches a constant pattern, which is an asymptotic shape beyond which the wave will not spread. The wave is said to be self-sharpening. (If a wave is initially broader than the constant pattern, it will sharpen to approach the constant pattern.) Thus, for an initially uniformly loaded oed, the constant pattern gives the maximum breadth of the MTZ. As bed length is increased, the constant pattern will occupy an increasingly smaller fraction of the bed. (Square-root spreading for a linear isotherm gives this same qualitative result.)... 

The same solution presented in Fig. 14 can easily be recast (see Ref. 22) into another form, as in Fig. 15. Note here that the maximum scaled response curve is now essentially a rectangular hyperbola with one asymptote which depends only on the level of applied peak force and another asymptote which depends only on the level of applied total impulse. In the intermediate loading regime (the "knee" of the hyperbola), response determination requires knowledge of both peak force and total impulse. 

As more chlorines are added in the polychlorinated biphenyl series (PCBs), the measured log Poct values taper off asymptotically to a maximum value of 8.55 (de Bruijn, 1989). This is most probably due to the fact that the l(h3M octanol which is present in the water phase is much greater than the amount of PCB, and it acts as a detergent/ sequestering the miniscule amount of any solute with log P>7.5. Of course, this may make measured octanol/water an improved model for many actual environmental systems. River water with a heavy load of sediment will adsorb hydrophobic solutes and appear to solvate them better than pure water. The only real problem in calculating the log Poct of PCBs whose log P<7.0 is allowing for the decreased hydrophobicity of chlorines in the ortho position. Again, most programs handle this reasonably well, as the examples in Table 5.6 show. 

The plant control system functions to limit temperature rates of change during plant load change and upset events. This is achieved at two different levels. In the time asymptote the control system through control variable set points (with values assigned as a function of steady-state power) takes the plant to a new steady-state condition. The set point values are chosen so that hot side temperatures remain little changed. In the shorter term the control system manages the dynamic response of the plant so that the transition between steady states is stable and with minimal overshoot of process variables.

The maximum of the curves corresponds to the static friction coefficient and the asymptotic value to the kinetic coefficient.3... 

This case, displayed in Fig. 1.17(d), occurs at a low inlet oxygen concentration or a high initial coke loading - that is, the combustion is oxygen-limited. The heat of combustion is carried away downstream by convection. For wr Wtherm the effective temperature rise approaches asymptotically the value... 

We first briefly review the effects of M on physical properties under monotonic loading conditions. Some properties, such as density and low temperature dynamic mechanical behavior, are essentially unaffected by changes in molecular weight. Other properties, such as the glass transition temperature, T, and the tensile strength, increase appreciably with M in the low molecular weight region but tend to approach an asymptotic value as M is further increased. Fox and Flory have shown that for PS the dependence of T on M can be expressed as... 

Saturability of the binding to the allosteric site also offers the potential to dissociate duration of effect from magnitude of effect. Since allosteric effects reach an asymptotic value upon saturation of the allosteric site, there is the potential to increase the duration of allosteric effect by loading the receptor compartment with large concentrations of modulator. These large concentrations... 

Creep tests are run by subjecting a grouted soil sample to a sustained load less than the short-term Unconfined Compression strength, until failure occurs. As the sustained load decreases in value, the time to failure increases. Data from such tests plot as shown in Fig. 11.22, and indicate an asymptote at what may be called a creep endurance limit. For acrylamides these values will range from as low as 20% Unconfined Compression for triaxial tests at low lateral pressure to as high as 40% for triaxial tests at at rest lateral pressures. (For silicates, values may be taken from Fig. 11.11.)... 

For each axial load, plot unit strain vertically against square root of time horizontally. For specimens that do not rupture, these data should plot as a curve which becomes asymptotic to the horizontal. If this trend is not occurring by 90 days, the test should not be terminated. 

We prove that the overall load of every threading with threshold 5 is at most 2/3 n. Since the number of 5-close vertices in 2-threading is 215 n asymptotically it proves that 2-threading is optimal for this threshold.
