During a practice of my presentation maria noticed that the scales on my b-scans were incorrect. This means that i have to go back through and first, edit my program. Second, get the program to run. Third, run the program for the 12 scans we did earlier.
The last couple of days have consisted of making minor changes to my presentation. As well as presenting it to maria and the other people in the BMI lab for constructive criticism. I changed my animated GIF images into AVI's to be played like movies, and to be more compatible with earlier versions of PowerPoint

Today i did some more research into TFT (Thin Film Transistors) on paper. once the paper is coated by sputtering, transistors are applied as if it was a silicon wafer. The finished product is an organic flexible display, that is applied to paper.

I started out today finishing up some of my 3D models of the surface of papers. Then i continued to work on my presentation. My hope is to finish this by Monday so maria and i can take a look at it and begin editing. Tomorrow will be more work on the power point and compiling the data that we have so we can sen it to Portugal(the people that asked us to study the papers).

Today maria wanted me to make 3D surface plots for all of the top surfaces of the paper. As I started to make them we noticed that the axis didn't line up the way we wanted them to. By that time it was lunch and i lose my computer to one of the grad students. So for the rest of the day I continued working on my presentation.
Today we did statistical analyses on our 2nd normalized moment. We noticed that in a few of the papers the moment was under 2 which meant that the A-line was a rice distribution. This means that there is a pattern in the substance as we move across. This corresponds with our previous images that showed a sort of line pattern from threads going up and down the paper.

Today was simply running the program with the 12 data sets i have. Later we will be looking at the results to see some correlation between the 3 ratios and the quality of the paper. These normalized moments can be used in the future for factory inspection to check the quality of every piece of paper that leaves the facility.
After a very long a hard day i finally got my program to work. The script randomly pulls 25 A-lines from a huge data set and displays them, then it allows the user to crop the data before calculating the normalized moments. All of this data is then exported to an excel file for future reference.

Today we finished up the last of cropping the A-Lines to create more detailed B-Scans. Each of these B-Scans are saved in a excel file as well as a jpeg of the B-Scan. Tomorrow i will begin editing the normalized moments script to calculate the moments of each scan.
