How a signal can be represented in time domain or frequency domain? Put simply, a time-domain graph shows how a signal changes over time, whereas a frequency-domain graph shows how much of the signal lies within each given frequency band over a range of frequencies. The “spectrum” of frequency components is the frequency-domain representation of […]
What page replacement algorithm has minimum number of page faults?
What page replacement algorithm has minimum number of page faults? MIN (minimum) or OPT (optimal) : Belady’s optimal algorithm for the minimum number of page faults. replace the page that will be referenced furthest in the future or not at all. problem: we cannot implement it, because we cannot predict the future. Why page replacement […]
How do you make a traffic light system?
How do you make a traffic light system? Participants in the Design of Traffic Light System by using State Design Pattern ITrafficLight- It will define the methods to change the state and report state. ConcreteState- It will be an implementation of ITrafficLight Interface. TrafficLight- It will behave as a context for the traffic light or […]
What is the difference between 1018 and 4140 steel?
How does diffusion coefficient change with temperature?
How does diffusion coefficient change with temperature? We note also that the diffusion coefficient increases strongly with the temperature of contact. The coefficient of diffusion increases gradually as the temperature of the air increases. The activation energy was calculated by using the Arrhenius equation for all simulators. Why diffusion coefficients of carbon in bcc and […]
How do facilitators ensure that a group works together effectively?
How do facilitators ensure that a group works together effectively? Answer: They organize the way a group meeting will run. They guide discussion so that everyone contributes equally. They resolve conflicts and make sure all opinions are heard. Which actions should be taken at the groups first meeting to ensure an effective project? Which actions […]
How does a double wishbone suspension work?
How does a double wishbone suspension work? How does double wishbone suspension work? Double wishbone suspension allows each wheel to act and react independently from the others. It achieves this thanks to two wishbone-shaped arms (also known as control arms or double A-arms) that are located between the knuckle on the wheel assembly and the […]
What safety factor should you perform before enter a curve or sharp turn?
What safety factor should you perform before enter a curve or sharp turn? Centrifugal force results in strong outward pull on your vehicle. So what you need to do before entering a curve is slow down. Lowering your speed when you’re already on a curve may cause your car to skid. Look for signs indicating […]
Why are water towers elevated?
Why are water towers elevated? The primary function of water towers is to pressurize water for distribution. Elevating the water high above the pipes that distribute it throughout the surrounding building or community ensures that hydrostatic pressure, driven by gravity, forces the water down and through the system. Where do cities put their water towers? […]
What is calibration error?
What is calibration error? The difference between values indicated by an instrument and those that are actual. Normally, a correction card is placed next to the instrument indicating the instrument error. Also called calibration error. What are the four types of errors? Errors are normally classified in three categories: systematic errors, random errors, and blunders. […]
