Student Talk Series: Sharon Garthwaite 11/10 @ noon in Olin 268

Title:  1+2+3+4+… = -1/12 Abstract: Infinite series. Every Calculus II student hates them; every mathematician loves them. So, why do mathematicians love infinite series? Well, ask one, and you’ll never hear the end of it… (just sum math humor). We’ll see how two standard examples of series, the geometric series and the zeta function (p-series), lead to beautiful applications, such as in economics and signal processing. We’ll also see how even divergent series are fascinating.

Student Talk Series: Mark Meyer 10/27 @ noon in Olin 268

Title:  Losing Altitude: A story of airplanes, heart rate, and one “controversial” dataset Abstract: When you ride in an airplane, the lowered pressure in the cabin causes your blood oxygen levels to decrease. If oxygen saturation levels go low enough, you may experience some interesting side effects (like temporary color blindness, for example), that much we know. What we don’t know is if there is also an impact on the functioning of the heart. Partially motivated by a rash of flight related medical case studies, a study was conducted in 2007 to more formally assess the effects of exposure to altitude […]

Student Talk Series: Charles Wessell, 9/29 @ noon in Olin 268

Title:  Electoral College Math:  How to Become President with 20% of the Popular Vote Abstract: The Electoral College makes it possible to become U. S. President with less than a majority of the popular vote. In a two-candidate election, what is the minimal percentage of the popular vote possible for a winning candidate? In this talk we’ll first mimic an approach suggested by George Pólya that to find a theoretical solution. We’ll then make use of of tools not readily available to Pólya – spreadsheets and binary linear integer problem software — to see if we can improve on his […]

Student Talk Series: Brian King, 9/15 @ noon in Olin 268

Title:  Sequential data mining Abstract:  Data representing DNA, proteins, literature, weather, and the stock market all share one common characteristic: their data are sequential. Sequence data present some of the most challenging problems for machine learning and data mining methods. In this talk, Professor Brian King will present a generalized, probabilistic framework for modeling sequential data. He will show how he and his students have adapted this model for classification and prediction tasks, reporting results from recent studies.

Student Talk Series: Karl Voss, 9/1 @ noon in Olin 268

  Title:  Being fair in a world of limited resources Abstract:  Fair division is a problem that all of us encounter regularly.  Every time you and another person or several people have to divide something – pizza, money, space, Neapolitan ice cream, band width, candy, etc. – you are working on a fair-division problem.  How can several people share a limited resource and make sure that no person feels the resulting allocation is unfair?   Before we can answer this question, we need to figure out what exactly is means to be ‘fair’.  The mathematical development of this subject is fairly […]

Student Talk Series: Alia Stanciu, April 21st @ noon in Olin 268

Title:  From airlines to healthcare: scheduling services with high variability Abstract:  What do the airline and healthcare industries have in common when it comes to managing their capacity? What makes scheduling surgeries so much more difficult than an airline’s management of its seat inventory? How can hospitals improve their surgical scheduling system? While most optimization models suffer from the curse of dimensionality, simulation-based optimization is often a better choice when dealing with demand that is highly variable. Drawing from revenue management techniques developed by the airline industry, I will show how simulation modeling can help hospitals to more efficiently schedule surgical […]

Student Talk Series: Matt Mizuhara ’12, March 24th @ 12 noon in Olin 268

Title: Mathematical biology under the microscope:  A study of cell motility Abstract: Although physics and chemistry have long relied on mathematics as a descriptive and exploratory tool, biological systems were historically seen as too complex to be understood theoretically. However, advances in mathematics and computational capabilities now allow for the quantification of biological problems in a field called mathematical biology. In this talk I will introduce a modern topic of mathematical biology: crawling cell motility. Cell motion plays a central role in wound healing and the immune response, e.g., to fight foreign bodies. We will present a partial differential equation model for […]

Student Talk Series: Lara Dick, February 25th @ 12 noon in Olin 268

Title:  There’s Nothing Common About It Abstract:  Training yourself to think like a child is often counterintuitive and surprisingly difficult.  My research focuses on helping preservice teachers analyze and learn from children’s mathematical thinking.  For this talk, we will focus on different types of story problems as described in the Common Core State Standards for Mathematics and discuss how children change their solution approaches depending on the situation presented in the problem.  We will watch videos of children solving different story problems and will consider various samples of written student work.  Audience participation will be encouraged.

Student Talk Series: Greg Adams, February 11th @ 12 noon in Olin 268

Title:  Monkeying around in South Africa Abstract:  As part of my sabbatical last year, I spent 5 weeks in South Africa at the Unizulu Science Centre in Richards Bay.  One of the highlights of my stay were the many encounters with vervet monkeys, both in the flesh and abstractly in mathematical problems.  They insist on playing a role in this talk. The science center serves the some 700 rural schools in the province of Kwazulu-Natal.  The level of mathematics achievement by the students at the rural public schools in South Africa is among the lowest in the world.  The science […]
