CSDT Work Monday, May 30 - Sunday, June 5

Monday, 5/30 10:30am-11:45am, 2:45-3:45pm:

          Found a Matlab script to run Fast Fourier Transform (FFT) and compute power series http://faculty.olin.edu/bstorey/Notes/Fourier.pdffunction)

• Adapted script to operate on input from .wav audio file

• Ran analysis on Bach pieces and white noise sample

• Did not find expected slopes for Power Series 

• 
  

• Tuesday, 5/31 12:00-2:45pm: 

• Bach pieces were recorded with instruments that did not vary volume (amplitude) with time.

• Ran power series analysis on Mozart piece played with violin, sample of 

• white noise (alpha = 0), and 1/f noise (alpha = 1)

• Did find expected correlation; Mozart slope appears close to alpha = 1:

Power Series analysis of Mozart Piece and Alpha = 0 and Alpha = 1 Noise

Wednesday 6/1 10:25-11:25am, 2:00pm-5:00pm

•      Edited Matlab script to select only the data in frequency range of interest (~1/(time of piece) to 0.5Hz))

•      Worked on setting script to compute slope of best fit line of LogLog plot

•      Attended meeting with design group; Goal: Run power series analysis on pitch 

•        sequence by this weekend

•      Helped transfer screenshots and print-outs of coordinates for Albany BGC Anishinaabe Arcs project

Friday 6/3 1:15-2:15pm, 3:30-5:30pm

•      Printed out Anishinaabe Arcs Projects

•      Taught Lesson #3 of Arcs Project at Albany BGC

•           Had students 1) Label graph paper with coordinate axis

•                        2) Plot point from their arc printouts

•                        3) Attach printouts to styrofoam and add bendable rods to 

•                           create their wigmwams

•      Students had far more difficulty with this than either of two previous lessons

•      3rd and 4th grade students were not familiar with using coordinate axis; they

       labled the axis, but not at even intervals, and they needed individual instruction

•      Probably 3 or 4 of about 16 students were comfortable plotting points without any 

       help by end of the session; some other students made significant progress

•      Students who learned helped their classmates

•      Perhaps target age group for activity could be 5th or 6th grade 

Saturday 6/4 2:00-2:45pm

     Worked on getting best fit line to logrhythmic plot of Power Series
     Difficulty adapting linear best-fit to logrhythmic plot
