compound action potential‚ the conduction velocity‚ and by quantifying the total and absolute refractory period between the nerve at room and cold temperature. An oscilloscope‚ preamplifier‚ and stimulator were used to stimulate the frog’s nerve located in the nerve chamber. Threshold voltage was determined by stimulating the nerve at increasing voltages until a compound action potential resulted. Absolute threshold was determined similarly by increasing the voltage until no further increase in amplitude

Introduction: The report focuses on data mining approach to predict human wine taste preferences. A large data set is considered with white and red wine samples (“Vinho Verde” wine from Portugal). The inputs include objective tests (e.g. PH values) and the output is based on sensory data (median of at least 3 evaluations made by wine experts). Each expert graded the wine quality between 0 (very bad) and 10 (very excellent). Due to privacy and logistic issues‚ only physicochemical (inputs) and

The absolute and relative refractory periods will be found by stimulating the nerve with a series of pulses. The velocity of the compound action potential as it travels down the nerve will then be calculated to determine the nerve conduction velocity. Lastly‚ the temperature sensitivity of nerve conduction velocity will be tested by measuring the speed at which the compound action potential travels down the nerve at both hot and cold temperatures. It was hypothesized that threshold voltage‚

In a plurality system (first past the post)‚ the candidate with the most votes will win the election. For an absolute majority‚ the winning candidate must achieve more than half of the votes to win. If no one achieves this threshold of at least 51%‚ there is a runoff election between the top two candidates of round one‚ eliminating the lowest ranked candidates
