Day 8: Back to the Tower

The group outside of Rokin' Roller Coaster
Hey guys! It's Jamie and Alex covering today's post. We'll take you through this morning's class, project time, and afternoon in Hollywood Studios.

RFID, Infrared, and Animatronics:
We took a break from our recent lectures on modeling and graph theory to talk about the technology behind many of the things that disney does well.

First up, Radio Frequency Identification (RFID). This is the tech behind the Magic Bands that Disney has implemented within the past several years. An antenna sends a signal to a transmitter in the band which in turn sends a data burst back to the receiver that includes your ID. A computer can then bring up your payment information, reservations, fastpasses and many other things. The Magic Bands have both a near and far field transmitter so that sensitive information can pass through a short range or basic information like your name can be recognised from a greater range. This is used to display your name on screens around rides. The Rockin' Roller Coaster that we visited today is a good example of this application of far field RFID.

Apparently, Dr. Harris is a real hit
Infrared is used mainly for security monitoring and statistic gathering. Instead of classic turnstiles, most disney attractions have an infrared gate that tracks how many people pass through. Further, infrared cameras are used throughout the park to keep surveillance in dimly lit areas such as dark rides.

Animatronics have been a big part of disney from the beginning, but the audio-animatronics that are used throughout the parks debuted in the 60's with the Enchanted Tiki Room, It's a Small World, and a life sized model of Abraham Lincoln. These designs have been dramatically improved since then and more modern attractions can manage stunning emulations of living people.

Project Work:
After class, we got back to work on our OR projects, and my group (Jamie) made some very good progress. We finally have a model to present to our classmates. Whether we can write it in a way that a computer can solve remains to be seen.

HOLYWOOOOOD!
After a break to finish up our projects, the group headed to Hollywood Studios for some free time! We spent a lot of the afternoon using FastPasses to ride some of our favorite attractions and see a new show. We started at Rockin’ Roller Coaster, but one time just wasn’t enough. The group ended up going back again but instead of waiting in the normal line, we went to the single rider line.

We have figured out by now that while it is nice sometimes to ride as a group, the single rider line is very fast and convenient, even sometimes quicker than FastPass. Our next stop on the agenda was Indiana Jones show, a show which mimicked being backstage as the movie crew shot stunts for the classic movie. We then went from one Harrison Ford movie to another: Star Wars. We all went through a minimum wait line for Star Wars Tours. Our group then headed to Tower of Terror.

Just like Rockin’ Roller Coaster, one time just was not enough. While for some of us (including me, Alex), the faces made on the photos are not planned. However for many, it’s always fun to plan a pose for the pictures!

Around dinnertime, the group broke off to either ride more rides or grab a bite to eat. We met up an hour or so later to ride Toy Story Mania while the line was minimum. Remember how we’ve mentioned a few times that our group was super competitive? The competition is still on. While I (Alex) may have beaten my personal record, I fell short of the winner: 189, 800 points. After the ride, we all walked back to Hollywood Scoops to get ice cream or ice cream sandwiches. This was the time too when a few of us broke off to ride Tower of Terror one last time for the day! The ride was a lot different in the dark than during the day, especially when the ride gets stuck for at least 10 seconds.

The fun for the day ended when we all realized that we needed to make a run to the grocery store once we got back. All in all, it ended up being another magical day in Disney and we're excited to present our projects tomorrow and meet some of Team Disney! Stay tuned for more math and the mouse!

Day 7: Takeovers, Rainstorms, and Bratwurst

Hello, everyone! Caroline and Johanna here to take you through our 7th day at Disney. Well recovered from our borderline traumatic day at Magic Kingdom, we began the day with a great lesson on graph theory and then visited Epcot for the second time.

Pick the Right Path

Today, we built upon our earlier work with network models to create shortest path models. Basically, we wanted to find the best path to get around a certain number of vertices based on different constraints. One constraint could have us not trying to hit every vertex, but every edge. Another could have us trying to hit every vertex only once and end up at our starting vertex. Finally, the professors introduced a problem where certain vertices and pathways had certain values, where the goal was to find the non-repeating path with the lowest total value. The vertices had different values depending on their order in the sequence, which made the problem simulate walk and wait times in a park. In one example, the vertices had different values depending on whether they were among your first four or last four, which resembled increasing wait times throughout a day at Disney. At the end of the session, Dr. Hutson introduced how the Traveling Salesman Problem, the basis of our Traveling Tourist Problem from yesterday, relies on a lot of the same data we used in our practice problems, and how companies like Touring Plans can make good solutions quickly for their clients.

OR We There Yet?
After class, we continued working on our OR problems. My group (Caroline) has made a lot of progress, and was actually able to start putting the pieces of our constraints together. Because each section of the constraint can be very long, we incorporated some Mouse into our math by naming each different section after a Disney character. Hopefully tomorrow we can begin consolidating our "characters" and have a model ready to present! My group (Johanna) has also made good progress. We are currently working on building generalizations from our constraints that make the strings of different variables we are summing more concise for the sake of both the computer and our classmates. Though we won't have a solution until we use a program like Mosel to calculate the problem, we have built a good bit of our model for Thursday, which is quite exciting!

Takeover Time
So, today, I (Caroline) had the opportunity to take over the Furman Snapchat as part of their showcase of different MayX courses. It was a lot of fun to be able to explain and update our activities in a way that would reach a lot of people. If you would like to see my story, follow furmanu on Snapchat, or look for it on YouTube!

Rain, Rain, Go Away!

Unfortunately, we had our first spot of bad weather today, but that did not keep us away from the parks. After class and lunch, we set out for Epcot, where we took advantage of the single rider line in Test Track, in what was probably one of the most efficient uses of the single rider line thus far in the trip. We made it on the ride in less than 5 minutes, just before inclement weather halted it indefinitely. From there, some of the group decided to test ourselves and our stomachs at Mission Space, where we learned that Zack is the last person you want on your space shuttle due to his inability to push buttons at the correct time. After Mission Space, a few of us ended up taking pictures with Baymax from Big Hero 6, who is as adorable as he is squishy, and who gave great hugs. After wandering around Epcot for a while, we all met up at the Land Pavilion to ride Living With the Land. Despite its slow pace, it was really interesting to see how Disney is a prominent facility for ecologically smart farming techniques. The food grown in the Epcot facility is actually used in the park. After the ride, we met with Furman student Haley Cottingham, who is just finishing an internship with Disney. Haley is a computer science major, and her internship actually deals with workforce scheduling, the same issue as our projects. She was able to give us a lot of information about the Disney internship program in general, and told us about all the possible career opportunities available at Disney. When we finished our visit with Haley, we had some time to kill before our dinner reservation, so we tried the ride in the Mexico Pavilion, and almost lost Dr. Harris when he nearly fell out of the boat!

Did Someone Say Bratwurst?

delicious German food
We ended the day with a delicious dinner at the German restaurant Biergarten. While we waited for the table, we explored the nearby shops, including a toy store and a glass and jewelry shop. When we finally entered the restaurant, we were floored. The restaurant is perfectly decorated and even featured a performance by a German band. Because it's buffet-style, we were able to try a whole spectrum of German foods, and we could get as much as we pleased. Some favorites were the schnitzel, the bratwurst and sauerkraut, red cabbage, and apple strudel. Due to the rain, we decided to opt out on a 2nd viewing of Illuminations, and made our way to the exit. We didn't let the rain dampen our fun, and we splashed and laughed our way to the van, ready to get some rest for another day.

Day 2: Modeling and Epcot

Morning:
Hi, everyone, Caroline and Jamie here! Today we had our first full day in Florida, and we began bright and early exploring some of the math aspects of Math and the Mouse. We spent the morning learning about the basics of Operations Research (OR) Modeling. This form of modeling seeks to accomplish a main objective under a certain set of constraints. For example, a bakery would seek to optimize profits with the constraints of limited ingredients or time. At Disney, OR Modeling is used to design incredibly detailed schedules for the cast members in the parks, who often are moving every 15-30 minutes. After looking at several examples of different OR Modeling problems, we split into groups to solve some problems on our own. One of the problems we examined in detail was the Knapsack Problem, which seeks to fit as many items as possible, with the greatest utility, or usefulness, in a set space. Later in the day, we learned that this problem would be a critical part of tomorrow's activity. After working through and presenting the problems, we set out for Epcot.

Epcot:
Our first stop at Epcot was in the big sphere itself, as we experienced Spaceship Earth. Soon, we moved to the much more exciting Test Track. We were a little parched after Test Track, so we went to the Coca-Cola Club Cool, where Dr. Harris and Dr. Hutson convinced several unsuspecting students to try the infamous drink Beverly. Luckily, the Flower and Garden Festival is going on currently, and there were many great exhibits and unique stops, including a Butterfly Garden.

Our next stop took us to the relaxing and almost sleep-inducing Journey into Imagination and The Seas with Nemo and Friends rides, though we did enjoy the air conditioning and seeing a dolphin. Following our time at the rides, we received our assignment for tomorrow, and split into our groups to formulate plans. From here, our smaller groups split up to see more of what Epcot had to offer.


Caroline:
After quickly finishing our project, my group decided to take advantage of the dinnertime short ride lines. Johanna and I had a great time on Mission Space and then enjoyed the quick wait for a second run on Test Track. After we had our fill of rides, we set out for the World Showcase, but not before I had my very first Dole Whip. We slowly made our way through all the pavilions, and ate our way through quite a few of them. We ended up enjoying teriyaki beef at Japan, gelato at Italy, and funnel cakes just in time for Illuminations. Even though Dr. Bouzarth assured me that the pavilions had not been renovated recently, I couldn't help but feel that they were so much bigger than when I last visited Disney! I could easily spend an hour in each pavilion, exploring the various shops and restaurants. Illuminations was just as exciting as I remembered, and was a great way to close out another day in Disney.

Jamie:
After a more tedious attempt at strategy, my group also went to Mission Space. While I was a bit queasy afterwards, it was quite fun.  Following that, we began our tour of the countries. We stopped for fish and chips in England, Bratwurst in Germany, and churros in Mexico. The national pavilions are fantastic with a variety of sights and tastes unique to each one. Following our walk, we regrouped with the others to watch Illuminations, a spectacular display of laser optics and pyrotechnics that left our ears ringing and our eyes dazzled. After so much excitement, we took the long slow walk back to the van to get some much needed beauty sleep.
