Earlier we considered the difference between local variables, which are available only within a particular procedure, and global variables, which are used throughout an entire project.
Each data type consists of many variables which are analyzed individually and as interacting networks.
Our approach can be easily implemented for other water quality variables which are dependent on streamflow.
Particular attention has been paid to "temperament" variables, which are considered to have a biological basis.
The proposed design method doesn't impose any constraints on slack variables, which are less conservative.
These factors are present as random variables which are spatially distributed across a region.
The heat exchanger has two input variables which are, cold and hot water flow rates.
Indeed, such variables, which are argued to be unmanageable, may affect the electricity utilities' performance.
New internal variables which are related to the orientation of particles are proposed.
The second element is a collection of variables, which are quantities whose values can be manipulated in order to optimize the objective.
Five variables, which are fracture spacing, fracture network size, fracture network conductivity, matrix permeability and reservoir size, were investigated.
