Context independent interface

Each solution is represented symbolically, so the user has no contextual clues as to what the problem is that he is attempting to solve. This is done in order to create a context independent interface that can be used for a wide variety of problems and algorithms. The only information to which the user has access is similarities between solutions (as shown by similarities in symbols) and the value of each solution. Once the user selects a set of solutions, he picks the type of variation operators to apply to the solutions and then presses GO to have the algorithm, as shown in Figure 8.1, create a new set of solutions. Dembski s work implies that even with only this information it is possible for the user to be able to provide active information to the search algorithm because a prior external source of information is unnecessary to add active information to the search since the user is an intelligent agent. [Pg.158]

We have mentioned above the tendency of atoms to preserve their coordination in solid state processes. This suggests that the diffusionless transformation tries to preserve close-packed planes and close-packed directions in both the parent and the martensite structure. For the example of the Bain-transformation this then means that 111) -> 011). (J = martensite) and <111> -. Obviously, the main question in this context is how to conduct the transformation (= advancement of the p/P boundary) and ensure that on a macroscopic scale the growth (habit) plane is undistorted (invariant). In addition, once nucleation has occurred, the observed high transformation velocity (nearly sound velocity) has to be explained. Isothermal martensitic transformations may well need a long time before significant volume fractions of P are transformed into / . This does not contradict the high interface velocity, but merely stresses the sluggish nucleation kinetics. The interface velocity is essentially temperature-independent since no thermal activation is necessary. [Pg.297]

Successful assembly requires matching features of the template, meaning that wavelength and height have to be of the same dimensions. Additionally, adhesion of particles and surface must be avoided by weak repulsive forces. In this context, polyelectrolyte multilayer-wrinkles are particularly useful, as the wettability of the multilayer is determined by the part of the layer adjacent to the film/solution or film/air interface respectively, while the elastic properties are determined by the total film [84], Thus, elastic constants can be adjusted largely independent from wettability properties. [Pg.88]

The experimental spectroscopic methods discussed below are performed in the steady state, i.e., the time average of the nuclei positions is fixed. This justifies the use of the time-independent Schrodinger equation in the calculations. Dynamical systems are also of some interest in the context of metal-polymer interfaces in studies of, for instance, the growth process of the metallic overlayer. Also, in the context of polymer or molecular electronic devices, the dynamics of electron transport, or transport of coupled electron-phonon quasi-particles (polarons) is of fundamental interest for the performance... [Pg.9]

While the calculations presented here were performed in terms of solution of Laplace s equation for a disk geometry, the nature of the electrode-electrolyte interface can be imderstood in the context of the schematic representation given in Figure 13.5. Under linear kinetics, both Co and Rt can be considered to be independent of radial position, whereas, for Tafel kinetics, 1/Rf varies with radial position in accordance with the current distribution presented in Figure 5.10. The calculated results for global impedance, local impedance, local interfacial impedance, and both local and global Ohmic impedances are presented in this section. [Pg.246]

The porous electrode theory was developed by several authors for dc conditions [185-188], bnt the theory is usually applied in the ac regime [92,100,101,189-199], where mainly small signal frequency-resolved techniques are used, the best example of which are ac theory and impedance spectra representation, introdnced in the previons section. The porous theory was first described by de Levi [92], who assumed that the interfacial impedance is independent of the distance within the pores to obtain an analytical solution. Becanse the dc potential decreases as a fnnction of depth, this corresponds to the assnmption that the faradaic impedance is independent of potential or that the porons model may only be applied in the absence of dc cnrrent. In snch a context, the effect of the transport and reaction phenomena and the capacitance effects on the pores of nanostructured electrodes are equally important, i.e., the effects associated with the capacitance of the ionic donble layer at the electrode/electrolyte-solntion interface. For instance, with regard to energy storage devices, the desirable specifications for energy density and power density, etc., are related to capacitance effects. It is a known fact that energy density decreases as the power density increases. This is true for EDLC or supercapacitors as well as for secondary batteries and fnel cells, particnlarly due to the distributed nature of the pores... [Pg.127]

The rate of evaporation of water decreases dramatically when a compact and coherent insoluble monolayer occupies the water-air interface (Gaines, 1966 La Mer, 1962). In this context, n-cetyl alcohol (n-hexadecanol) is a well-studied insoluble surfactant which forms such monolayers. A simple explanation is that a significant part of the interfacial area available for evaporation is blocked by the monolayer. Even at a liquid-liquid interface, a resistance to mass transfer is sometimes observed when a solute crosses the interface as it transfers from one liquid into another. This resistance appears to be independent of the convection in the liquid, suggesting that it lies solely at the interface (Chen and Lee, 2000). [Pg.360]

All the above contributions are presented as self-contained independent chapters. This has inevitably led to some element of repetition and overlap of content. In my opinion, this contributes positively to the book by providing alternative data, literature, opinions, and interpretations. Many partly answered and unanswered questions remain. Perhaps the most pertinent lie within the context of the antioxidant/prooxidant balance of ascorbic acid within different tissues and disease situations and the detailed understanding of the hydrophilic/hydrophobic interface between water-soluble ascorbic acid and the lipid-soluble antioxidants, vitamins E and A. Thus, the door remains wide open for many future investigations. [Pg.451]

Duplex films the film is sufficiently thick to give complete independence between the energy of the surface and that of the interface where in the present context the surface is the air-oil surface and the interface is the interface between the oil and the foaming liquid. [Pg.58]

This chapter is concerned with the study of liquid interfaces. Liquid interfaces would mostly mean droplets, vesicles, or bubbles. Bubbles and "nanobubbles," in particular, have been studied extensively in the context of slippage and the long-range hydrophobic attraction.Today they are studied by numerous groups independently of these specific applications. This chapter only covers a rather narrow subtopic of this research field. We show in the second part that nanobubbles look like stiff objects when investigated with ultrasonic shear waves. [Pg.284]

The safety requirement for the system was formally stated independently of any outline design, based on its behaviour in the context of system interfaces. Formulation of the safety requirement was only possible once its impact on wider system behaviour was analysed in the context of the environment. [Pg.248]
