Variability, definitions

When more than one variable is allowed to vary, then all possible combinations of their values will be included. For example, the following variable definitions will result in a total of 20 scan points ...

Data transposition is the process of changing the orientation of the data from a normalized structure to a non-normalized structure or vice versa. There are many definitions of normalization of data, and you should learn about normal forms and normalization. Here, in brief, normalization of data means the process of taking information out of the variable definitions and turning that information into row definitions/keys in order to reduce the overall number of variables. Normalized data may also be described as stacked, vertical, or tall and skinny, while non-normalized data are often called flat, wide, or short and fat. ...

The number of equations and unknowns must balance. Thus, one can calculate the appropriate number of needed relationships from the degrees of freedom of a system, as shown for various systems by Newman. In terms of the relations, the equations can be broken down into five main types. The first are the conservation equations, the second are the transport relations, the third are the reactions, the fourth are equilibrium relationships, and the fifth are the auxiliary or supporting relations, which include variable definitions and such relations as Faraday s law. 

Consider a solitary wave, progressing to the left in an open channel, with celerity (wave velocity) c. We may replace this situation with the equivalent steady-flow case in which the wave stands still while the flow enters at velocity Vi = -c. Writing the energy equation, Eq. (10.122), between points 1 and 2 (with Z = z2, oq = a2 = 1, and neglecting friction), and keeping the same variable definitions, we have... 

Variable definitions AX (xylan conversion, %) AG (glucan conversion, %) l (inoculum amount, mg of P. ostreatus/g of stems) M (moisture content, g of H20/g of stems) t (time, d). 6 DOF, degrees of freedom for the regression analysis. 

This is the definition assumed in the work of Shoup and Szabo [507] and Aoki and coworkers [57,61,62] and also by Gavaghan in some recent works [260,261]. The above three formulae (12.9, 12.11 and 12.12), are those for this definition of normalised time. One inconvenient side-effect of the definition is that, when one normalises the diffusion (12.2), using the new dimensionless variables definitions...

A mixture of methane, ethane, and argon at 25 C is burned with excess air in a power plant boiler. The hydrocarbons in the fuel are completely consumed. The following variable definitions will be... 

The pressure scale is usually found indirectly by substituting all the other non-dimensional variable definitions into the momentum equation.
