.2.3 Time series models Time series is an ordered sequence of values of a variable at equally spaced time intervals. Time series occur frequently when looking at industrial data. The essential difference between modeling data via time series methods and the other methods is that Time series analysis accounts for the fact that data points taken over time may have an internal structure such as autocorrelation‚ trend or seasonal variation that should be accounted for. A Time-series model explains

conducted in series and parallel to identify the pressure different in both pumps. Centrifugal pump is known as one of the most widely used pumps for transferring liquids. It’s also known as a device to transfer mechanical energy from a prime mover into fluid energy to produce the flow of liquids. The pump is connected in 2 ways; in series and another as parallel pump. Centrifugal pump are connected in parallel because to provide enough flow rates compare to centrifugal pump that connected in series‚ the

Title: Resistors in Series and Parallel Date: 17/7/05 Aim: The aim of this experiment is to compare the predicted and actual resistance in a circuit of resistor combinations in series and in parallel. Background: A resistor is an electrical component/device that has electrical resistance. Resistors can be used in electric circuits for protection of components‚ voltage division or current control. In an ideal resistor the resistance remains constant regardless of the applied voltage or current
