Interface, defined

The geometry of Fig. 10.3 leads to a result known as Snell s law, which relates the refractive index of the medium to the angles formed by two wave fronts with the interface. Defining 6q and 6, respectively, as the angles between the phase boundary and the wave front under vacuum and in the medium of refractive index n, show that Snell s law requires n = sin Oo/sind.

The fact that the curvature of the surface affects a heterogeneous phase equilibrium can be seen by analyzing the number of degrees of freedom of a system. If two phases a and are separated by a planar interface, the conditions for equilibrium do not involve the interface and the Gibbs phase rule as described in Chapter 4 applies. On the other hand, if the two coexisting phases a and / are separated by a curved interface, the pressures of the two phases are no longer equal and the Laplace equation (6.27) (eq. 6.35 for solids), expressed in terms of the two principal curvatures of the interface, defines the equilibrium conditions for pressure ...

Three model areas can be distinguished. Model areas allow defining separated areas in the value chain network to be optimized separately. Model areas can be defined by clustered resources and/or products that have clear interfaces. Defining model area eases the implementation of a comprehensive value chain planning optimization model for a complex value chain network the optimization model can be tested for parts of the value chain network with limited data complexity before extending the model to the entire network. Three model areas are defined in the industry case study ...

The change in volume of the aqueous layer and the appearance of the interface define the water reaction of the fuel.

As discussed by Andersen [9, 10] for muffin-tin orbitals, the locally regular components y defined in each muffin-tin sphere are cancelled exactly if expansion coefficients satisfy the MST equations (the tail-cancellation condition) [9, 384], The standard MST equations for space-filling cells can be derived by shrinking the interstitial volume to a honeycomb lattice surface that forms a common boundary for all cells. The wave function and its normal gradient evaluated on this honeycomb interface define a global matching function %(cr). 

The measured reflectivity, R(Q), depends upon the neutron refractive index profile perpendicular to the interface, defined as the z-direction. The neutron refractive index is a function of the scattering length density, Nb, which is the product of the number density N, in units of nuclei per cm3, and the neutron scattering lengths, b, of the nuclei present. Since the neutron scattering length varies from nucleus to nucleus, chances in the nature and composition of the surface result in changes in reflectivity.

SCSI Acronym for small computer system interface. A high-speed, system-level parallel interface defined by the ANSI X3T9.2 committee. SCSI is used to connect a personal computer to several peripheral devices using just one port. Devices connected in this way are said to be daisy-chained together, and each device must have a unique identifier or priority number. 

To proceed we need to determine the nature of the interface defining the surface pressure- or stress tensor. For the general non-equilibrium circumstances T/ is a non-isotropic and non-symmetric tensor, containing six... 

Module A module is a logical unit of a software system with a clearly defined purpose in a given context. It consists of an export interface defining which resources (data and/or operations) the module offers to the rest of the system, an import interface defining which resources from other modules the module may use to realize its export interface, and an implementation in some programming language. The internals of the module (the implementation or body) are encapsulated. Therefore, a module can be viewed as an abstraction the interface provides access to abstract resources the module abstracts from the realization of these resources. The term interface of a module, without further qualification, refers to the export interface. Furthermore, a module is the atomic architectural unit of reuse. Modules can be used in a context or system different from the one in which they were developed.

When a beam of light travelling in air, refractive index n0 = 1, passes through a glass plate, refractive index 2, a part of the incident light will be reflected on the front and rear surfaces, as shown schematically in Fig.2a. The reflectance R of a glass/air interface, defined as the ratio of the reflected intensity to the incident intensity, is a function of the difference in the refractive indices of the media and may be expressed for normal incidence as ...

Here is the eharge of ehemisorbed anions. The layer parallel to the interface, defined by the point of nearest approaeh of hydrated ions, is called the outer Helmholtz plane and the one at eorresponding to the position of chemisorbed anions is called the inner Helmholtz plane. Ions loeated in the inner layer are in direet eontact with the surface, without the interposition of water molecules. This phenomenon, referred to as chemical adsorption or spec adsorption, particularly concerns certain types of anions, the most important from a eorrosion point of view being ehloride. In order to study specific adsorption, the experimental eharge of the double layer is compared to the predictions of the Stern model and the difference is attributed to specific ads option.
