Imagine a valve control system without compromises, one that isn’t crank-driven and doesn’t play by conventional rules. Such an engine would allow infinitely variable timing on all its valves ...

The main variables in a science experiment are the independent variable, the dependent variable and the control variables. The independent variable is what we change or control in the experiment.

Does the system actually work? Okay, it’s not perfect. For a start, and in a very un-McLaren bout of wanton imprecision, Variable Drift Control, as featured on the 720S Coupe and Spider, isn’t ...

Controlled variable – a variable that is kept the same during a scientific investigation to ensure a fair test so that results can be compared.

What is a variable wattage control system for electric heaters? What are the advantages of these types of control systems? Are there any safety issues with variable wattage control systems? If so ...

Sorting by CONTROL variables is available for systematic and sequential selection methods, which include METHOD=SYS, METHOD=PPS_SYS, METHOD=SEQ, and METHOD=PPS_SEQ. Sorting provides additional control ...

This is a survey paper on the application of control variables to increase the efficiency of discrete event simulations. The emphasis is on the practical problems and potential of applying the method ...
