Data management reaction-based

TTie classification of kinetic methods proposed by Pardue [18] is adopted in the software philosophy. TTie defined objective of measurement in the system is to obtain the best regression fit to a minimum of 10 data points, taken over either a fixed time (i.e. the maximum time for slow reactions) or variable time (for reactions complete in less than 34 min, which is the maximum practical observation time). In an analytical system generating information at the rate of SO datum points per second, with reactions being monitored for up to 2040 s, effective data-reduction is of prime importance. To reduce this large quantity of analytical data to more manageable proportions, an algorithm was devised to optimize the time-base of the measurements for each individual specimen. 

METEOR S biotransformation rules are generic reaction descriptors, and the versatile structural representation used in the system allows each atom or bond to have specific physicochemical properties. This approach provides more details than simple hard-coded functional group descriptors (313), but this flexibility also can give rise to an avalanche of data. METEOR manages the amount of data by predicting which metabolites are to be formed rather than all the possible outcomes (310,312,314,315). At high certainty levels, when chosen, only the more likely biotransformations are requested. At lower likelihood levels, the more common metabolites are also selected for examination. Currently, METEOR knowledge-based biotransformations are exclusively for mammalian biotransformations (phase I and phase II) (314,315). 

Note that widely different mixts all follow a single curve. The horizontal lines I and II are theoretical computations. Une I is based on a frozen sound velocity and line U is based on an equilibrium sound velocity. Clearly the former provides a better fit (at large d/a) to the exptl data than the latter. Frozen sound velocity is computed under the assumption that compn and entropy remain constant, while for equilibrium sound velocity one assumes the chemical reaction manages to follow the changes in the expansion isentrope. Vasil ev et al suggest that the larger-than-theoretical values of (c—u)/D at small d/a are due to an increase in c because... 

Step 5. Each near miss tree as such generates a set of classifications of elements which have to be put into a data-base for further statistical analysis. This means that a NMMS is not meant to generate ad-hoc reactions by management after each and every serious near miss report on the contrary, a steady build-up of such a database until statistically reliable patterns of results emerge must be allowed in order to identify structural factors in the organisation and plant instead of just unique, nonrecurring aspects. 

The detailed mechanism in most cases will be too complicated to be handled effectively, especially when macroscopic phenomena is under scrutiny. Therefore, the mechanism should be reduced carefully to a manageable size, systematically. Sensitivity analysis based on a constraint and a choice of parameters will render some of the mechanism steps ineffective in the overall analysis, similar to the pseudoequilibrium hypothesis done in earlier kinetic analysis work. But this time, elimination is based on some rigorous analysis with substantial information on the kinetics, and not on a simplifying assumption to be validated against data fitting. Eor sensitivity analysis, one has to select model responses, such as conversion, selectivity, and rate. Then, the sensitivity of the model response to the parameters is analyzed. For example, the sensitivity analysis of reaction rate r, with respect to the Arrhenius preexponentials can be done by constructing a sensitivity matrix with the elements of...
