Day 14

Today, my lab partner and I sieved a 400 gram sample of gravel. We found that almost all of the gravel was retained on the very top sieve after putting the sample through the sieve shaker. Therefore, we didn't do any more trials with these sieve sizes. We are considering using larger sieve sizes on the sample for trials 2 and 3. After the sieving, I started the manual image analysis using ImageJ for one of the microscopic images of the clay&silt (image attached below). I will continue working on it when I get home as well.

Day 1

Today was the first day of my internship. We had a brief meeting in the morning and then went to get our ID's, computer accounts, and parking permits. After, Joe explained a team-building activity that we would be working on for the rest of the day: a scavenger hunt. All of us were given the same packet of objects/people that we needed to find around campus. In the end, we were tasked with making a movie that consisted of all the video footage we took of the different objects/people. At 4pm, Joe and two other judges evaluated our project and calculated the total points we received as a group. The scavenger hunt was a good way for us to get to know each other and discover more about the campus. Finally, before we went home, we each met with our advisors and learned more about what we would be doing throughout the course of the internship.

Day 20

My lab partner and I continued working on our PowerPoint in the morning. I took a picture of the clay & silt sample using the camera because our other one was not clear enough for the image analysis. I continued working on and finished the manual image analysis for the sand image and transferred the data onto a spreadsheet. However, after binning the data, we noticed that the particle size distribution did not match our data from the sieving trials for sand. We asked our advisor and he said to redo the image because the cropped version messed with the pixel sizing of the image. After lunch, I went to a MS thesis defense on visual perception. The title of the presentation was "A Tool for the Analysis of Human Interaction with Two-Dimensional Printed Imagery. I also started working on a new manual analysis of the sand image in ImageJ and finished before I left. Chris said that he will give us some advice on our presentations next Monday and after we can start the wet sieving if

In the morning, Joe read over Amy's abstract and gave her some feedback. Then, we all went down to Brian's lab on the second floor. He explained his project to us and showed us the eye tracking device that he uses, which tracks the movement of your pupils. The research done in the visual perception lab with this device could be used to track how people behave in the presence of money and where their eyes looked. There are specific symbols on paper money that distinguish real currency from their fake counterparts. This device can track where experts look specifically for the symbols. After Brian showed us around his lab, we all went to our labs. Chris looked over my finalized test plan and made some minor changes. Before lunch, since we had nothing else to do, Hannah and I decided to do a test run of the sieve shaker with a sand sample we found in one of the cupboards. We used the entire container of sediment, which weighed about 997 grams. We turned on the sieve shaker for a li
