Dependence defined

By Noether s theorem, invariance of the Lagrangian under an infinitesimal time displacement implies conservation of energy. This is consistent with the direct proof of energy conservation given above, when L and by implication H have no explicit time dependence. Define a continuous time displacement by the transformation t = t + oi(t ) whereat/(,) = a(t ) = 0. subject to a —0. Time intervals on the original and displaced trajectories are related by dt = (1 + a )dt or dt = (1 — a )dt. The transformed Lagrangian is... [Pg.17]

The dependence defined by the equilibrium equation of state (4) is depicted in Fig. 2A. As a result of the competition between the entropy and interaetion terms in Eq. (4) the surfaee tension changes very little for small surface coverages. As the coverage increases beyond about the surface tension starts decreasing until reaching equilibrium. This qualitatively explains the shape of dynamic surface tension curves found in experiments for non-ionic surfactants (e.g. [8,20]). We have reproduced in... [Pg.60]

This paper reviews the detailed hydrodynamics of Outokumpu flotation cells by using Computational Fluid Dynamic (CFD) modelling. This includes different computational grid type dependency defining in the CFD model and examining the flow pattern induced in the cell as well as validating the model. [Pg.960]

Equations (7.4) and (7.5) are completely general statements that there are some functional dependences S U, V,N) and U(S, V, N), and that these dependences define T, p, and p. Equations (7.4) and (7.5) are fundamental because they completely specify all the changes that can occur in a simple thermodynamic system, and they are the bases for extremum principles that predict states of equilibria. An important difference between these fundamental equations and others that we will write later is that S and U are functions of only the extensiv e variables. Beginning on page 111 we will show how to use Equations (7.4) and (7.5) to identify states of equilibrium. [Pg.109]

An example of the IMF resulting from the variation in secondary ion yields with emission velocity is shown for the Silicon isotopes from Silicon under 0 impact in Figure 3.35. Note The secondary ion mass fractionation observed (F) is depicted in units of permil. This exhibits trends over higher emission velocities (inverse velocity values less than 1.5 X 10 s/cm) consistent with the velocity dependence defined in Relation 3.10(a) (Gnaser and Hutcheon 1987). The deviations at lower emission energies appear to be consistent with those noted in Figure 3.30 with speculated reasons for these deviations covered in Section 3.3.2.2.2. [Pg.111]

The influence of excitation processes on the ionization and/or neutralization processes/s active on the atomic emissions produced through sputtering. These have been used to explain the deviations from the velocity dependence defined in Relations 3.10(a) and (b), with examples displayed in Figure 3.30 for the Cu secondary ion emissions arising from Ar , 02, or Cs impact. Excitation processes are discussed in detail in Section 3.3.2.3. [Pg.112]

Then assuming system components dependence defined by (13) and applying directly the formulae (16)-(17) and (19), we get the system reliability function... [Pg.261]

To study chemical dynamics, it is often sufficient to restrict the electronic basis to the ground state electronic wave function, ( o(r> R), and this choice will be assumed throughout this work. The associated electronic energy, o(R)> is seen to depend on the particular structure of the molecule, R. This dependence defines the topology of the potential energy landscape on which the nuclear dynamics happens. [Pg.85]
