Title of Talk: Intro Stats Project: Handwriting and Gender
Abstract: Can you tell the gender of a writer from a sample of handwriting? A simple survey leads provides perhaps surprising answers. The resulting data set proves unexpectedly rich in terms of the number of questions students can ask. Most of the questions are suitable for a first course in statistics for a general audience. (Side questions: Many math departments are asked to teach elementary statistic courses. Is this math? Should it be?)

Title of Talk: Using Playdough and 3D Prints to Visualize Volumes
Abstract: Using two-dimensional images to visualize three-dimensional objects can be challenging. Instead, playdough and 3D prints can help us better understand different shapes and their cross sections. Let’s have some fun with these physical representations of objects to more clearly illustrate and help our students learn how to, for example, set up volume integrals.

Title of Talk: Explicit Constructions of Functions whose Graphs are Dense in The Plane
Abstract: A set D is dense in the plane if and only if every open ball in the plane contains an element of D. We prove that there exists a function f from the real line R to itself whose graph is dense in the plane by explicitly constructing it using a partition of the rationals into countably many subsets dense in R. We then use this method of construction to prove that there are 2^(2^\aleph_0) functions whose graphs are dense in the plane, and that there exists a function f: R ->R such that f(U) = R for every non-empty open set U in R.

Title of Talk: An Algorithm for the Detection of Transient Neural Oscillations
Abstract: The analysis of neural activity through measures of electrical potential affords researchers great opportunity to understand in detail the dynamic nature of certain brain processes. Electroencephalography (EEG) and Local Field Potential recording (LFP) are two of the most common methods for measuring this activity. Both are essentially recordings of the electrical potential over time in a highly localized segment of the brain, and produce data sets that can show surprising amounts of structure. Oscillations with very well defined frequencies are the most common examples of structure within these recordings, and a large portion of modern neuroscience research focuses on how different frequency bands of these oscillations relate to different modes of activity for the organism being studied. Such signals can easily be detected and quantified automatically with traditional signal processing tools such as the Fourier transform. However, there also exist very transient oscillations within such recordings that are of interest to researchers. These require more sophisticated techniques to detect, because of their dual localization in both the time and frequency domains. A combination of several classic signal processing tools, namely digital band-pass filters, the Hilbert transform, z-scoring, and numerical derivatives has yielded an efficient and accurate algorithm for the detection of such transient oscillations. This algorithm has been applied to LFP data for sleeping rats and used to detect the well-known phenomena of sleep spindles, which are a hallmark of late stage sleep in mammals.

Abstract: Coe has been using a "Math Culture Points" system for several years now to encourage and reward students for relevant activities outside of class, inspired by the article "Culture Points: Engaging Students outside the Classroom" by Fraboni and Hartshorn in PRIMUS v17. We have had excellent results, particularly including enthusiastic student participation in activities. We will discuss our implementations of the system, which differ from Fraboni and Hartshorn

Title of Talk: Constructing the Naturals -- An Inquiry-Based Approach
Abstract: The construction of the natural numbers via the Peano Axioms is a strangely neglected backwater of the undergraduate curriculum. It deserves more attention. Meanwhile, although inquiry-based learning has gained some traction, it usually is considered a binary decision, where a course either is or is not taught using an IBL approach. I propose a standalone unit, giving our number systems the foundation they deserve, and offering a "trial size" taste of IBL.

Subject area(s): Combinatorial games theory
Title of Talk:
Abstract: I conducted research in the summer of 2006 dealing with the game of Hex, the two player combinatorial game developed independently by Piet Hein and John Nash. I wanted to know if modifying the game board by removing available playing spaces would effect the outcome of the game. I analyzed a 3x3 size board, then a 5x5 board, and some preliminary work on a 7x7 board.

Title of Talk: Orthogonal Polynomials on the Cantor Set
Abstract: The middle-thirds Cantor set is an uncountable set of Lebesgue measure zero. The Cantor measure is defined such that it assigns the Cantor set measure one, and has the Cantor set as its support. An orthogonal polynomial sequence (OPS) is traditionally defined by means of Riemann integration, but more generally an OPS can be defined by means of integration with respect to a measure. First we construct the Cantor measure and show it satisfies the properties of a measure. Then, we verify the existence of an associated OPS by examining the positivity of its moment matrix. Finally, using the Gram-Schmidt method we construct the OPS, and derive various properties of the polynomials based on results for classical orthogonal polynomials.

Title of Talk: Fractals: A Basic Introduction
Abstract: We present a basic introduction to fractals by looking and understand the concept of Hausdorff dimension and Topological dimension by looking at simple examples of classic fractals and geometric constructs. We also define the Julia set and Mandelbrot set as an iterative function on the complex plane and present some examples together with some historical remarks.

Title of Talk: Toward an integrative model of suction feeding using the immersed boundary method
Abstract: Suction feeding is among the most common forms of aquatic prey capture. During a suction feeding strike a fish rapidly opens its mouth creating a fluid flow that draws in the prey. This is an example of indirect prey capture; the fish does not directly manipulate the prey, but rather the fluid flow around the prey. Previous studies of suction feeding have either studied jaw mechanics or the flow field in isolation, or have only considered rigid jaw motions (think of a fish mouth as a collection of metal plates). In this talk I will describe work in progress to develop a new methodology to study fish suction feeding that relaxes some of these conditions. In particular we will allow for more realistic flexible jaws and examine how the kinematics of the jaw motion affects the resultant flow field and subsequent prey capture.

Title of Talk: An Elementary Solution to a Problem of Ramanujan's Interest
Abstract: In the early 1900's, Srinivasa Ramanujan discovered an intriguing, yet exotic, integral that he believed could have a 'simple', beautiful closed form. However, he never gave a simple solution to this integral. It wouldn't be until the mid-1950's when Russian mathematician V. I. Levin revisited Ramanujan's integral. He used non-elementary calculus techniques to prove that the integral, indeed, had a closed form for a single parameter; however, that parameter was only defined for positive integers. The integral would not be fully explored for the sake of itself until half a century later. Recently, V. Adamchik found that exact same integral that Ramanujan had encountered nearly a century ago. He showed a closed form using methods of Euler sums and related non-elementary techniques. This presentation will show a closed form of the integral does exist, but use only methods of elementary calculus. In addition, these techniques can be used to extend the result to double parameters!
