experiments, the correction seems to be significant at the low salinities (less than0.9 Mho/m). Furthermore, since the down-hole MWD tool is operated at 2 MHz, a set ofcorrected data is essential for the tool calibration and the raw data correction. Therefore, thecorrection at the higher frequencies, such as 2 MHz, which is essential for MWD logging, hasbeen developed.Bibliography 1.

While Internet access is taken for granted on U.S. campuses, this may not be the case during a study abroad, and certainly was limited and expensive (30 to 50 cents per minute) on the Semester at Sea experience.

Hence the capacitor voltage represents the water tank level. Potentiometer R1represents the drain on the tank by the customers. The pump is modeled by a current sourcerealized as a current mirror. The current in the matched transistors of the LM3046 are controlledby the PLC output connected to Q1. The output voltage at the PLC output corresponds to thepumping rate. In this laboratory, the students would use an oscilloscope to monitor the capacitorvoltage at node 5. These first two laboratories lay down the model for the PLC as a robust and reliablecontroller.
