The answer is B. A only. The optimum valve timing is found through experimentation using an engine dynamometer. The timing of the opening and closing of the valves is called valve timing. So the use of dynamometer measures the power output of a machine that is why it can measure the optimum valve timing.
No. When you purchase software, it is usually distributed under a license that only lets you do certain things with it. It is usually only for personal use, but other times the manufacturers of the software will allow you to freely redistribute it.
<u>Windowing</u> is the detection of events that fall inside a specified set of parameters, such as within or outside of a specified time frame.
<h3>What is windowing?</h3>
Windowing is the process of processing and analysing a small subset of a bigger dataset. The rectangular window is a crude method that merely truncates the dataset before and after the window without altering the contents of the window in any way.
A windowing system allows many apps to simultaneously share a computer's graphical display presentation resources. You might want to utilise several programmes simultaneously on a computer with a graphical user interface (GUI) (this is called task).
Therefore, windowing is detection of events within a given set of parameters, such as within a given time period or outside a given time period.
