data acquisition

Computer experiment is crucial for marine controlled-source electromagnetic (CSEM) forward modeling in hydrocarbon exploration. Marine CSEM computer experiment is used to discretize the governing equations of the electromagnetic (EM) fields. One dimensional (1D) simulation usually is fully utilized to determine the reliability of the higher dimensional marine CSEM computations. All the data were generated using Web Hosted Active-Source Modeling (WHAM) online resource.

Ultrasonic transit time difference meters are prevelent in industry due to their ease of use and lack of moving parts. But, They often suffer from a cross-sensitivity to the speed of sound in the fluid, which is dependent on the temperature. Other factors like changes in the flow profile or trigger jitter in the signal can also have a large impact on the accuracy to which measurements can be made.

In order to obtain the constants of our PID temperature controller, it was necessary to identify the system. The identification of the system allows us, through experimentation, to find the representation of the plant to be able to control it.

The first data with name "data_2.mat" represent the open loop test, where the sampling frequency is 100 [Hz], this data was useful to find the period of the pulse train generator, which is twice the slowest sampling time analyzed between the high pulse and low pulse of the input.
