Connectivity, defined

The intermediate phases formed in the various binary systems have been represented, in a first approximation, as point compounds. The points, which in the different binaries correspond to phases having the same composition and structure, have then been connected, defining multi-component ternary stability fields (in this case, line fields). On each horizontal line of this multi-diagram triangle the same overall composition is found (the same Mg content and the same total... [Pg.247]

Bertz 83a) used the number of connections (defined as the number of pairs of adjacent edges) to introduce the index C(q), called the complexity of a molecule. [Pg.46]

The laws of electromagnetism are based on the theory of gauge fields. The electromagnetic vector potential defines components of a gauge connection 1-form. This gauge connection defines a field strength 2-form ... [Pg.432]

The texture of precipitated silica-alumina depends on the texture of the silica when silica results from a sol-gel transition. The condensation of silicic acids leads to the formation of primary spherical particles (sol) which aggregate in defined conditions, forming the tridimensional network of the gel [1]. In the gel framework each primary particle of silica is connected to two or three particles [1] and the gel pores are the cavities existing between these particles [2], The size of the particles, conjugated to their connectivity, defines the surface area, the volume and diameter of the gel pores. Thus, the silica texture could be controlled by mastering the size and the packing of the silica particles [3], characteristics which depend on the conditions of preparation of silica sol and gel. [Pg.623]

The atomic walk count is a measure of something like involvedness or centrality of the atom in the graph, i.e. a measure of the complexity of the vertex environment. Moreover, the atomic walk count is the - extended connectivity defined by Morgan [Razinger, 1982 Rucker and Rucker, 1993 Figueras, 1993]. [Pg.480]

The X matrix [Hall, 1990] is the most popular weighted distance matrix, based on the path contributions arising in constructing -> connectivity indices. Using the vertex degree 8 of the atoms, each path pij between the vertices v, and vj is weighted by the path connectivity defined as ... [Pg.487]

Structurally these are the wells defined by completely I, completely O or mixed 170 neighborhoods. They give rise to potential wells which are shallow (T), shallow-deep (170 ) and deep (O ). Their connectivities lead to shallow-shallow, shallow-deep and deep-deep combinations. The Ag ions present in wells generated by shallow-shallow interactions contribute most to the conductivity, because their mobilities depend upon connectivity of wells in the glass structure. Thus the well depths and connectivities define both the diffusion path and the mobility. [Pg.238]

A generalization of the concept of edge connectivity, defined in terms of vertex degrees, is given by the following expression ... [Pg.472]

Biochemical Connections Define omega-3 fatty acid. [Pg.233]

Connectivity defines the arrangemoit and number of pore coimections. For monosize pores, coimectivity is the average number of pores per junction. The term represents a macroscopic measure of the number of pores at a junction. Coimectivity correlates with permeability, but caimot be used alone to predict permeability except in certain limiting cases. [Pg.5]

Listed to the right of each category, as applicable, are the Standard and Limited Standard connections for each gas. ANSI/CGA V-1, American National, Compressed Gas Association Standard for Compressed Gas Cylinder Valve Outlet and Inlet Connections, defines small cylinders as those with a capacity less... [Pg.137]

Connections, defines small cylinders as those with a capacity less than or equal to 110 in. (1.80 L 1.81 kg water). [1] For a discussion of the valve connections that may be used on such cylinders, which include those termed lecture bottles, readers are referred to CGA V-1 (paragraph 2.8 of the 1987 sixth edition). [Pg.134]
