Heaviside unit step function is a function that can $$switch on$$ and $$switch off$$ at a given term

at a specific value of time. One of the examples is to use Heaviside unit step function to switch

on or off the voltage in an electrical circuit at a pre$-$described time. The applications for

Heaviside unit step function include the machine deep learning and control theory.

Demonstrate ONE $(1)$ application of Heaviside unit step function in following industry such

as Mechanical$/$Chemical$/$Electrical & Electronics$/$Robotic of your choice. You can include

the introduction$/$background$/$history of the unit step function, follow by the problem statement,

then clearly show the formulation steps to yield the solution and draw conclusion. Figure$($s$)$ or

diagram$($s$)$ that can aid the explanation may be included.

Please show how to solve it for chemical engineering and please attach the figures
