Control variable definition: a person, group, event, etc., that is used as a constant and unchanging standard of comparison in scientific experimentation.. See examples of CONTROL VARIABLE used in a sentence.
A control variable is a variable that is held constant in a research analysis. The use ofcontrol variablesis generally done to answer four basic kinds of questions: Is an observed relationship between two variables just a statistical accident? If one variable has a causal effect on another, is...
Here, the temperature is the controlled variable. At the same time, it is the input variable since it is measured by a thermometer and used to decide whether to heat or not to heat. The desired temperature (20°C) is the set point. The state of the heater (e.g., the setting of ...
standard form (known as the Bolza form): Determine the state (equivalently the trajectory or path), x(t)∈Rn, the control input, u(t)∈Rm, the initial time, t0∈R, and the terminal time, tf∈R (where t∈ [t0, tf] is the independent variable) that optimize the performance index:...
Strategy 1: \(({u}_{1}=\mathrm{0,}{u}_{2}\ne \mathrm{0,}{u}_{3}\ne \mathrm{0)}\) In this strategy, we set the control variable u 1 = 0 zero and the rest of the control variables are non-zero, this effect can bee seen in Fig. 2, (sub-figures (a–c)) and...
The findings demonstrated extensive road network simulation with the integrated simulation platform, multidimensional control variables, control strategies with support, as well as stable and reliable operation. It can be used to verify several sorts of traffic control simulation with variable dimensions....
For example, given the following simple protocol: protocol SomeProtocol { func doSomething() } You can use an extension to add protocol conformance, like this: struct SomeStruct { private var privateVariable = 12 } extension SomeStruct: SomeProtocol { func doSomething() { print(private...
In this definition, the result of<Expression>is matched against each value set and<Value set>must be an expression or a range. 注意 <Expression>can't be an application object variable, since application objects don't have a comparator. ...
