Integration procedures

Integrated safety testing is included in hardware and software test plan and procedures. [Pg.48]

System-level hazards attributed to the subsystem are analyzed, and adequate control of the potential hazard is implemented in the design. [Pg.48]

The SSHA shall be generated in concurrence with the SHA to support the CDR, [Pg.48]

The O SHA must identify the safety requirements or alternatives needed to eliminate or control identified hazards, or to reduce the associated risk to a level that is acceptable under either regulatory or contractually specified criteria. It shall document the system safety assessment of procedures involved in system production, deployment, installation, assembly, test, operation, maintenance, servicing, transportation, storage, modification, and disposal. [Pg.48]

Note that the definite integrals in the members of the elemental stiffness matrix in Equation (2.77) are given, uniformly, between the limits of -1 and +1. This provides an important facility for the evaluation of the members of the elemental matrices in finite element computations by a systematic numerical integration procedure (see Section 1.8). [Pg.53]

Taking as the reference system an unsheared monolayer (o. = 0), the thermodynamic integration procedure in Eqs. (107) permits one to construct the plot shown in Fig. 17. For = 0, A = 0 vanishes for the monolayer as expected. As increases, A rises, indicating that the sheared mono-layer is increasingly less stable. A bilayer film, on the other hand, becomes increasingly stable as > 0.5, eventually intersecting the monolayer curve at As increases from 0.0 up to the monolayer is the thermodynamically stable phase because its A is smallest for the bilayer... [Pg.55]

In the component balance equations, dY]/dt will therefore be zero, whereas dXj/dt may still be quite large. This can obviously cause considerable difficulties in the integration procedure, owing to equation stiffness. [Pg.200]

TRUE when the integration procedure has completed an integration step. [Pg.683]

Furthermore, the implementation of the Gauss-Newton method also incorporated the use of the pseudo-inverse method to avoid instabilities caused by the ill-conditioning of matrix A as discussed in Chapter 8. In reservoir simulation this may occur for example when a parameter zone is outside the drainage radius of a well and is therefore not observable from the well data. Most importantly, in order to realize substantial savings in computation time, the sequential computation of the sensitivity coefficients discussed in detail in Section 10.3.1 was implemented. Finally, the numerical integration procedure that was used was a fully implicit one to ensure stability and convergence over a wide range of parameter estimates. [Pg.372]

Figure 8 shows the result of the integration procedure for compound 1 it can be presented either as a curve above the signal concerned or, as in this case, as a series of numerical values under the spectrum. Even in the case of pure compounds the integration values are not perfect, but the errors are so small that the ratio of the numbers of protons can be easily determined these... [Pg.12]

Because of the irregular shape of an atom in a molecule, this integration is not trivial and can be time-consuming. For many molecules, however, it can now be carried out on a personal computer in a reasonably short time. A discussion of integration procedures is given by Popelier (1999). [Pg.153]

On the basis of automated peak picking and integration procedure, after less than 2 h, the enantiomeric purity was established. R S ratio was 34.4 65.6, which is close to the values obtained from the 1H or 13C NMR spectra. [Pg.129]

If azimuthal averaging is used for the purpose of isotropization, a geometric problem from the 3D world is taken for a 2D problem57. For the field of polymer science the correct integration procedure has already been described in 1967 by Desper and Stein [148],... [Pg.145]

We can view the classical— quantum transition another way, namely through the potential rather than the kinetic energy. If we substitute (1 — X)AUa(x) + XAUa[x r) for zW/ . x(r) in the quantum correction term of (11.22), and then follow through with a thermodynamic integration procedure, we obtain... [Pg.409]

Figure 12.5. If desired, these small effects can easily be exactly included by letting the simulation program output all the relative energy levels for the experimentally used frequency and for the canonical orientation that corresponds to geff = 10.4, and then using these values in Equation 12.3. The outcome of Equation 12.3 for a given experimental temperature is required for spin counting (determination of the concentration of the S = 7/2 system) using the single-peak integration procedure explained in Section 6.2. Figure 12.5.

Show that the integration procedure over the Gamow peak implies for that peak a 1/e full width of A = (4/ /3)-s/(E0kT),le. essentially twice the geometric mean of Eo and kT. [Pg.48]

A brief summary will be given of the Newmark numerical integration procedure, which is commonly used to obtain the time history response for nonlinear SDOF systems. It is most commonly used with either constant-average or linear acceleration approximations within the time step. An incremental solution is obtained by solving the dynamic equilibrium equation for the displacement at each time step. Results of previous time steps and the current time step are used with recurrence formulas to predict the acceleration and velocity at the current time step. In some cases, a total equilibrium approach (Paz 1991) is used to solve for the acceleration at the current time step. [Pg.180]

In addition to definite integration, KACSYKA can perform numeric integration using the Romberg numeric integration procedure. There are a number of other numeric techniques available. And, one has the ability to evaluate expressions numerically to arbitrary precision. [Pg.108]

The solution of the problem requires integration procedures along pseudo-binary lines that result in the combination of integral forms of the type in equation 2.101. In this context it is unnecessary to proceed further with detailed treatment, for which reference may be made to Lewis and Randall (1970). [Pg.119]

In general, the Leighton relationship is expected to hold when reactions (4) and (6) are the major loss processes for N02 and 03 [reaction (5) is essentially always the loss process for 0(3P)]. Under such circumstances, the Leighton relationship can be used in computer models of tropospheric chemistry to minimize computation time. Thus, instead of carrying out numerical integration procedures separately to obtain [03], [NO], and [N02], if two of the three concentrations are known, one can obtain the third by using Eq. (A). [Pg.266]

Based on the considerations set out above, we shall now develop a model which treats more systematically some features of the process of decision taking by a multi-faceted individual. In Sections I and II, on the one hand, we emphasized the different aspects or points of view pulling the individual in different directions, thus making him a Faustian decision-taker. In Section III, on the other hand, we discussed the individual s integrating or fusing process of the many different aspects. Both the aspects taken into consideration by the individual and the integrating procedure employed are much more... [Pg.210]

Integration of systems of nonlinear partial differential equations (54),(86) has been performed [33,49]. Here we indicate the principal steps of the integration procedure. While integrating (54),(86), we essentially apply the fact that the general solution of system of equations 1,2 from (86) is known [62]. With already known (x) in hand, we proceed to integrating linear partial differential equations 3,4 from (86). Next, we insert the results obtained into the remaining equations and get the final forms of the functions (x), ). [Pg.327]

Integration of the stationary electro-diffusion equations in one dimension. The integration of the stationary Nernst-Planck equations (4.1.1) with the LEN condition (4.1.3), in one dimension, for a medium with N constant for an arbitrary number of charged species of arbitrary valencies was first carried out by Schlogl [5]. A detailed account of Schlogl s procedure may be found in [6]. In this section we adopt a somewhat different, simpler integration procedure. [Pg.108]

Acrylic Polymers. Burrows et al. [95] showed by the Integral Procedural Decomposition Temperature (IPDT) method that for main group metal ions -the stabilizing effect in regard to polyacrylamide is inversely proportional to the radius of the metal ion reemphasizing that the strength of the complex between the ion and the polymer is of importance in deciding the stability. [Pg.111]
