- Computer-Augmented Laboratory: This experiment is the first in a series of exercises that are part of a course designed to familiarize chemistry students with the theory and practice of automated data collection, data processing and computer control of experiments.
The students are instructed to assume a linear response for their thermistor over the 0-100°C temperature range and calibrate it accordingly by measuring the voltage at the temperature extremes. This provides them with a δT/δV value which can be inserted into the linear equation in their data collection program.They record the temperatures for their thermometer and thermistor as well as the raw voltage over the whole range (HOT=>COLD) at intervals of ~5°C.
A curve of T vs V is plotted and the linear least squares best fit line (trendline) and the correlation coefficient (R²) are determined.
If the results of the linear fit are not satisfactory, a second or third order polynomial or exponential fit is attempted.
Finally, the students rewrite their data collection program to handle the corrected equation and verify experimentally that the thermistor response is now accurate.
Hardware/Software Design: This program, written in LabVIEW (National Instruments), is designed to control the operation of 16 cages, monitor the reactions of the test animals, administer a predetermined dose of narcotic and output a data file of their activity. The program utilizes 64 digital channels. The input bits correspond to a “dummy” lever and “real” lever for each of the 16 cages which monitor the “learning progress” of the test subjects. The output bits correspond to the light and pump which stimulate the subject and administer the drug, respectively, for each of the cages. Parameters, which can be set for each cage, include the number of lever hits required for a dose, the maximum number of doses that can be administered and the length of time that the light and pump will be on. The output file, which contains all of the activity occurring during the experiment, is in an Excel-ready format.
Hardware/Software Design: A hardware/software combination affording a rapid and accurate determination of the photosynthesis - light irradiation relationship (P vs. I) was developed. By interfacing an oxygen electrode/amplifier system directly to a PC, it is possible to evaluate the in situ production rate of oxygen, dO2/dt, for different light intensities and subsequently produce an overall "P vs. I" curve for symbiotic coral-algae systems in a realtime environment. Parameters are calculated for an inverse quadratic as well as for a hyberbolic tangent fit.
