    CONTINUOUS TIME INTENSITY - REPORTS

SIMS 2000 has been enhanced with continuous time-intensity following the guidelines outlined in the ASTM E-18 document: ASTM E1909 - 97(2003) Standard Guide for The Time-Intensity Evaluation of Sensory Attributes.

A few key definitions include:

I max Peak Intensity, maximum observed intensity during the time of measurement
Area after I max Post-peak area under the curve
Area before I max Pre-peak area under the curve
AUC Area under the curve (total)
Rate of increase Rate of intensity increase before peak intensity (slope)
Rate of decrease Rate of intensity decrease after peak intensity (slope)
T init Time of initial exposure, typically when clock starts
T onset Time point when the sensation is first perceived after initial exposure
T max Time to reach maximum intensity of the sensation after exposure
T plateau Duration of peak intensity
T dur Duration time of sensation
T ext Time to extinction, Time when the sensation can no longer be perceived
T trun Truncate Time


SIMS 2000 uses the same flexible Line Scales for Time Intensity data collection. Data reporting and analysis includes textual summary and detail reports, individual panelist time-intensity graphs, entire panel time-intensity graphs (using key curve parameters method) and Curve Parameter Analysis Summary using Panel Means by Sample with Significance Test (p-value).

   Continuous Time Intensity
   -------------------------

     SIMS 2000 Continuous Time-Intensity follows the guidelines outlined in the ASTM E-18 document:
     ASTM E1909 - 97(2003) Standard Guide for The Time-Intensity Evaluation of Sensory Attributes.

     SIMS 2000 uses the same flexible Line Scales for Time Intensity data collection.
     Data reporting and analysis includes textual summary and detail reports, individual panelist
     time-intensity graphs, entire panel time-intensity graphs (using key curve parameters method) 
     and Curve Parameter Analysis Summary using Panel Means by Sample with Significance Test (p-value). 
     SIMS 2000 uses SAS to generate the stats output columns for p-values and sample separation letters.

       A few key definitions include:
         I max:  Peak Intensity, maximum observed intensity during the time of measurement
         Area after I max:  Post-peak area under the curve
         Area before I max:  Pre-peak area under the curve
         AUC:  Area under the curve (total)
         Rate of increase:  Rate of intensity increase before peak intensity (slope)
         Rate of decrease:  Rate of intensity decrease after peak intensity (slope)
         T init:  Time of initial exposure, typically when clock starts
         T onset:  Time point when the sensation is first perceived after initial exposure
         T max:  Time to reach maximum intensity of the sensation after exposure
         T plateau:  Duration of peak intensity
         T dur:  Duration time of sensation
         T ext:  Time to extinction, Time when the sensation can no longer be perceived
         T trun:  Truncate Time


   Analyze Key Curve Parameters
     SIMS 2000 is designed to use SAS statistics to generate the statistical output columns 
     for p-values and sample separation letters.   Straight forward GLM procedure, X1-X14.


   Advanced, Data Edit
     Hopefully you should rarely need to edit individual Continuous Time Intensity Data.
     1 Data Set via Excel.  You can edit one at a time, i.e. a panelist sample single attribute's Observations.
     Flexibility exists for Copy-n-pasting from one panelist to another, one sample to another, etc. 
     Proceed with caution.  Consider practicing with a 'Copy' of your real SIMS 2000 Test Result Code.
     All of these advanced edit import events will be fully logged by the SIMS 2000 system event logs.
     General Use Instructions:
       - Export to Excel ONE Data Set you would like to Edit.  One panelist one completed TI attribute.
       - Make your editing changes in Excel and only within the Response Column.
       - Select (highlight) just the Response Column.  Do not select any other columns.
             For your current Attribute named Sweetness, is expecting 100 Rows.
       - Copy to Clipboard (use Edit Copy, or CTRL-C from within Excel).
       - From SIMS 2000, press button for Excel Import.
