Monotonic increasing response surface

Figures 2.2, 2.3 and 2.4 show relationships between y, and Xj that always increase or always decrease over the domains shown. The lowest and highest values of the response y, lie at the limits of the x, factor domain. Figure 2.2 is a response surface that is monotonic increasing that is, the response always increases as the factor level increases. Figures 2.3 and 2.4 show response surfaces that are monotonic decreasing the response always decreases as the factor level increases.

In Fig. 39, the three Stokes shifts show distinct relationships with tryptophan s emission maxima and ascertain the dominance of solvation response from surface water hydration. The first component AE shows a monotonic increase... 

One of these constituent curves is attributed to a fast response to one of the volatile compounds emitted from the TNT based explosives. Some traces of saturated signal can be related to these fast responses. In addition to the fast term, the curve representing much slower response to the smell is also visible in the measured signal. This constituent curve superimposes the fast response. There is no tendency towards the saturation in this constituent curve representing the slow response term. Monotonous increase of this term indicates a poisoning of the surfaces by some of the volatile compounds. 

These considerations may also explain the nonmcmotonic frequency responses with vapor partial pressure observed for adsorption of non-polar molecules onto the quartz surface of a SAW sensor [114]. Since it is well known that surface coverage increases monotonically with partial pressure, these trends are inconsistent with a simple mass-loading interpretation. In this paper, the authors no-posed a coverage-dependent SAW-adsorbate interaction to explain the anomalous results for the weaker binding non-polar s )ecies (no anomalous trends were observed with polar adsorbates). 

Myoelectric control derives it name from the electromyogram (EMG), which it uses as a control input. When a muscle contracts, an electric potential (the EMG) is produced as a by-product of that contraction. If surface electrodes are placed on the skin near a muscle, they can detect this signal (Fig. 32.26). The signal can then be electronically amplified, processed, and used to control a prosthesis. While the intensity of the EMG increases as muscle tension increases, the relationship is a complex nonlinear process that depends on many variables, including the position and configuration of the electrodes (Heckathome and Childress, 1981). Although the EMG is nonlinear it is broadly monotonic, and the human operator perceives this response as more or less linear. 

There are some informations about monotonous decrease of the equilibrium surface tension, dilatational elasticity, and adsorption of lysozyme for non-ionic surfactant decyl dimethyl phosphine oxide (Cj DMPO) as the concentration of surfactant increases in the mixture. However, in the case of mixtures of non-ionic surfactants with more flexible proteins like P-casein, the elasticity of the interfacial layer decreases before passing through a maximum as the concentration of surfactant increases [7], Possibly, the weaker interfacial network formed by P-casein as compared to globular proteins determines the dilatational response of the mixtures. The same picture was shown for the system P-casein mixed with dodecyl dimethyl phosphine oxide (C,2DMPO). For all studied frequencies (0.005-0.1 Hz) the elasticities for adsorption layers have a maximum about 4x10" mol/1 Cj2DMPO concentration. It was shown the obtained values are very close to those measured for the surfactant alone. Thus, in this concentration region the surfactant dominates the surface layer. In our case we have...
