User-defined variables

Vertex constraint maximizers are not assumed, although they are expected to be common. Both local and global searches into the interior of V may be carried out as part of the search procedure, the effort expended in finding a new constraint maximum being bounded by user-defined variables. 

The variable three state celLljst is a user-defined variable which lists the instances of three-state cells.

User-defined variables are scoped, which means that a variable is valid only in its defining block. In HardwareC, variables are declared in statement blocks therefore, variables declared in a Block node are valid only in its children. The... 

Temporary registers hold internal values that do not correspond to user-defined variables. They are created as a result of hardware sharing. If a resource component is shared among multiple operations, then the outputs of the resource component may have to be latched so that the results of each diff nt invocation of the resource component are retained even if the component is reused subsequently. 

Type declaration—Must be placed after CONST sequence and before variable declarations used to define nev (not predefined) data types either as a range of values or as specific values within parentheses and to define arrays, records, and files. User-defined scalar types are ordered in increasing lefl to right sequence. For example. 

In 2000, Krishnamurthy et al. have presented the 2/,3/-HMBC experiment (Figure 20), that affords for the first time the means of unequivocally differentiating between 2/ch from 3Jch correlations.59 Their approach is based on a further derivative of the constant-time variable delay introduced in the IMPEACH-MBC experiment. The user-definable /-scaling factor of the CIGAR-HMBC is used in the new experiment, the 2J,3J-HMBC experiment, to differentiate between 2/CH from 3Jch correlations. This new pulse sequence element has been given the acronym STAR (Selectively Tailored Accordion F1 Refocused) operator. 

The RNG model provides its own energy balance, which is based on the energy balance of the standard k-e model with similar changes as for the k and e balances. The RNG k-e model energy balance is defined as a transport equation for enthalpy. There are four contributions to the total change in enthalpy the temperature gradient, the total pressure differential, the internal stress, and the source term, including contributions from reaction, etc. In the traditional turbulent heat transfer model, the Prandtl number is fixed and user-defined the RNG model treats it as a variable dependent on the turbulent viscosity. It was found experimentally that the turbulent Prandtl number is indeed a function of the molecular Prandtl number and the viscosity (Kays, 1994). 

Optimisation may be used, for example, to minimise the cost of reactor operation or to maximise conversion. Having set up a mathematical model of a reactor system, it is only necessary to define a cost or profit function and then to minimise or maximise this by variation of the operational parameters, such as temperature, feed flow rate or coolant flow rate. The extremum can then be found either manually by trial and error or by the use of numerical optimisation algorithms. The first method is easily applied with MADONNA, or with any other simulation software, if only one operational parameter is allowed to vary at any one time. If two or more parameters are to be optimised this method becomes extremely cumbersome. To handle such problems, MADONNA has a built-in optimisation algorithm for the minimisation of a user-defined objective function. This can be activated by the OPTIMIZE command from the Parameter menu. In MADONNA the use of parametric plots for a single variable optimisation is easy and straight-forward. It often suffices to identify optimal conditions, as shown in Case A below. 

Different baseline correction methods vary with respect to the both the properties of the baseline component d and the means of determining the constant k. One of the simpler options, baseline ojfset correction, nses a flat-line baseline component (d = vector of Is), where k can be simply assigned to a single intensity of the spectrum x at a specific variable, or the mean of several intensities in the spectrum. More elaborate baseline correction schemes allow for more complex baseline components, such as linear, quadratic or user-defined functions. These schemes can also utilize different methods for determining k, such as least-squares regression. 

MATLAB has a built-in root finder for scalar equations f(x) = 0 in one real variable x that are in standard form. The built-in MATLAB function is fzero. The use of fzero hinges on a user-defined function, such as the function f inside the following fzero tester, called fzerotryl, that we apply to our previously studied third degree polynomial. 

Using automation software routines for the ASPECT 3000 pulse generator, we can utilize up to nine ejection/activation pulses, each combining up to four options. Mass (or frequency) information is taken from several variable user-defined lists, such that each option in each event may be used on a large number of masses. The variable mass and delay lists can be defined either via alphanumeric keyboard input, or they can be defined interactively from the spectrum via cursor. Each acceleration/ejection event can contain up to 4095 different steps. All events can be separated by fixed or incrementable delays. 

With the help of the study team, data management usually prepares the validation procedures document to identify specific variables that must be validated. Edit checks may be defined as part of the data structure and executed during data entry. Programmed checks are user-defined checks executed off-line during batch validation. 

The simplest method based on an exhaustive examination of all the possible models of k variables (i.e. the model size) obtained by a set of p variables, where k is a parameter between 1 and a user-defined value (the maximum theoretical value is limited by the number n of objects in the data set). The best model or models is or are evaluated by validation or by parameters depending on the models degrees of freedom. 

For quantitative validation of simulation results, it is often necessary to compare predicted profiles (of velocity or other variable of interest) with experimental data X-Y plotting facilities are useful for this purpose. Most post-processors allow the user to import tabulated data for comparison with simulation results. Facilities to calculate the usual global quantities of interest to reactor engineers, such as overall pressure drop, dispersed phase volume fraction, heat or mass transfer rates and so on, are necessary to address reactor engineering concerns. Most codes allow use of user-defined routines to evaluate different quantities of interest, which may then be displayed using the standard tools discussed above.
