The enclosed dataset is the compressed file ('.rar'), which consists of 
1) a table in word. listing the information of all the experiments, 
2) 84 data files ('.txt') of the smoothed data (~every 60 - 120 datapoints) for all the experiments performed. 
3) 198 graphs showing the preliminary results ('.emf').  The title of the individual graphs correspond to the names of the data files.  
Note that one single experiment may contain 2-5 data files (i.e., segments of records) for different stages of the experiment. In each data file, the head lines (up to ) give the information of data processing. Here is the example (LHV25520003_Fric_Coef_)
