The new functions a release is to contain are incorporated in the existing product during the SAP SDLC. This involves extending the existing process and data models and adding to the application documentation and test catalog. New test case descriptions for new functions are added to the test catalog. New process chains that link the old and new functions in test scenarios are included as test cases.

We have checked, using as a test case, that the description of the optimum orbital of the molecular system is then complete in the sense that it allows (assuming that the orbital energy is known) to construct by a fit process an optimum orbital which is very close to the one obtained by a diagonalisation process in a gaussian basis. 

The function of TOGA is to transform the results of chemical analysis, together with descriptive information about a transformer, into a diagnosis of transformer condition and a recommended action. The rules were created by a process of successive refinement, using the HSB data base of past transformer histories as a source of test cases. 

Validation. TOGA was validated by conqjarlng Its diagnoses to those previously made by the expert who supplied the rules. A set of 859 test cases from a historical data base were used. The data base contained the gas analysis results, transformer descriptive Information, and the expert s detailed diagnoses (which had been prepared several years before TOGA was built). None of the cases were used In rule construction. 

The dissociation of difluorine is a demanding test case used traditionally to benchmark new computational methods. In this regard, the complete failure of the Hartree-Fock method to account for the F2 bond has already been mentioned. Table 1 displays the calculated energies of F2 at a fixed distance of 1.43 A, relative to the separated atoms. Note that at infinite distance, the ionic structures disappear, so that one is left with a pair of singlet-coupled neutral atoms which just corresponds to the Hartree-Fock description of the separated atoms. 

Validation deviations during the project must be managed. Details of deviations must be recorded with a description of the circumstances under which the deviation was noted (e.g., reference to design review or test case) and the name of the person noting the deviation. A record is also required...

Table II gives a general description of the program features such as total number of elements, aqueous species, gases, organic species, redox species, solid species, pressure and temperature ranges over which calculations can be made, an indication of the types of equations used for computing activity coefficients, numerical method used for calculating distribution of species and the total number of iterations required by these models for each of the two test cases. The chemical analyses for the two test cases are summarized in Table III. The seawater compilation was prepared in several units to assure consistency between concentrations for proper entry into the aqueous models.

Test cases that will be handed out to the test person are prepared by the quality assurance (QA) department together with the development team. The documents include the scope of the test with a link to the requirement specifications document, the system configuration, background information on the function to be tested, detailed test description and expected results. During and after testing, the test person completes the sheet with his name, actual results and any comments on findings. 

The function ffjl is derived analytically from the hard-sphere-collision integral, and readers interested in the exact forms are referred to Tables 6.1-6.3 of Chapter 6. One crucial issue is the description of the equilibrium distribution with QBMM. In fact, since the nonlinear collision source terms that drive the NDF and its moments to the Maxwellian equilibrium are approximated, the equilibrium is generally not perfectly described. The error involved is generally very small, and is reduced when the number of nodes is increased, but can be easily overcome by using some simple corrections. Details on these corrections for the isotropic Boltzmann equation test case are reported in Icardi et al. (2012). 

Ghose and Crippen [89] first worked on this approach on a more theoretical basis. Later, Smellie et al. [90] applied this methodology to real test cases. Billeter et al. [91] combined the description of molecules by distance constraints with an efficient algorithm for constrained optimization. 

Many statistical models have been applied to reaction (3.1), and it might be considered a test case for theoretical treatments of the rate constant. The process inverse to (3.1), the dissociation of ethane, has also been extensively studied experimentally25,26 and theoretically.116,2 2,27 The theoretical predictions for the rate of dissociation are, of course, quite sensitive to the value of the bond dissociation energy. On the other hand, recombination rates depend only weakly on that quantity. In the present review, attention is focused on the prediction of the recombination rate using the transition state theory outlined in Section IIC. First, the high-pressure limit of kr, denoted by kK, is considered, particularly its temperature dependence. This is followed by a brief description of some results for the pressure dependence of kr and for the dissociation of a vibrationally excited C2H6 molecule. 

For the water-metal interaction, extended tests of the dependency of results on the basis set used were also performed using the CU-H2O dimer as a test case. The full electron description was used for the reference system. The results, calculated using the B3LYP method combined with different basis sets, were compared with those obtained at the standard HF and MP4 levels. Consequently, the least extended LANLIMB basis set was chosen for copper and the tests were focused on the choice of the basis set for the water molecule. Of all tests performed the B3LYP/ MB-6-31G method was found to give the best estimates for the CU-H2O system. An energy of -37.5 kJmol was obtained with this basis set for the ion-copper interaction the reference level defined by the MP4/full electron calculations is —42.3 kJmol. It should be mentioned that both results are close to the experimentally suggested estimate of the interaction of the water molecule with the copper electrode,ca -35 kJmoL. ...

The approach to the Rock Mechanics Site Descriptive Model was tested by predicting the rock mechanics properties of a 600 m x 180 m x 120 m rock volume at the Aspb Hard Rock Laboratory (HRL) in Sweden using limited borehole data of the type typically obtained during a site investigation (Hudson, 2002). These predicted properties were then compared with best estimate properties obtained from a study of the test rock volume using additional tunnel and tunnel borehole data. This exercise was known as the Test Case, and directly indicates how some of the input required for modelling can be specified and tested. 

The Test Case exercise was invaluable in forcing the generic approach to the Rock Mechanics Site Descriptive Strategy to become a specific approach for the Aspd HRL rock volume being considered. The predictions of the rock mass modulus between fracture zones made by the empirical and theoretical teams were similar and close to the best estimate values. The predictions of the rock mass modulus in fracture zones were more varied, because few data were available and hence there was greater choice in the assumptions necessary to make the predictions. The empirical and theoretical teams predictions of the rock strength were also more varied, mainly because few data were available and different interpretations of rock mass strength were used. 

The essentials of the SSEA for numerically compufed energy-normalized N-elecfron wavefunctions were published in 1994 by Mercouris ef al. [54], The firsf application was not only to the multiphoton ionization of H (whose specfrum is known exactly analytically), as a test case, but also to the multiphoton detachment of the four-electron Li negative ion, with two free channels, Li ls 2s S and ls 2p P°. Li (or Be) is the first system of fhe Periodic Table for which the proper description of the zero-order electronic structure requires a multiconfigurational Hartree-Fock (MCHF) description. In the context of the review of the SSEA, we also discuss briefly the formulation of the problem in terms of the full atom-EMF interaction,Vext(f), which is computationally convenient as well as necessary for certain problems involving, say, off-resonance coupling of Rydberg states, for which use of just the electric dipole term is inadequate [55-57]. 

User acceptance testing (UAT) demonstrates that the application software meets the expectations of the user, based on the URS/functional description. It checks if the application software works in practice and is demonstrated by test cases/scenarios. 

The workflow should be broken down to manageable chunks each of which become a target for a round of hazard analysis and perhaps our what-if questions. It is at this stage that detailed hazards, causes and controls can be established which will form the bulk of the hazard register. The system business processes themselves may be derived from a number of different sources depending on the material available. Some systems may have detailed use cases with primary and exception flows carefully documented. For others the processes may need to be ascertained from training material, product descriptions or test cases.

The usage model and profile are descriptions of the intended operational usage of the software. A reliability prediction is conducted based on test cases generated from a usage profile and is always related to that profile. Hence, a reliability prediction must always be stored in the experience base together with the usage profile used.
