Welcome to Women In Mathematics @ UA

The Women In Mathematics group is a community of female math faculty and students who work together to provide support and resources for women in math at The University of Akron. WIM encourages women to pursue studies and careers in mathematics by organizing events such as seminars given by female speakers. The main goal of WIM is to retain more women mathematics students at all levels, from undergraduate through graduate, and to provide them with a strong network of support.

Title: Mathematical Modeling of Cellular Blebbing

Abstract: A biological cell is the fundamental unit of life. Cell migration is a necessary process for embryonic development, wound healing, and immune responses. In order to migrate, signaling proteins trigger cytoskeletal remodeling and substrate adhesion that result in translocation. Accomplishing these tasks requires highly coordinated chemical and mechanical responses. Mathematical modeling is an important tool for determining how components in such a complex system interact with each other in order to understand the overall biological system. In this talk, I will discuss mathematical modeling of cellular protrusions called blebs, the role of blebs in cell migration, and the synergy between mathematics and biology.

Title: Making Better Business Decisions: Where Math Can Help? Where it Can't?

Speaker: Valerie Tardif, PhD, Director of Product Management at GT Nexus and Adjunct Professor at Carnegie Mellon University

Abstract: After 30+ years in the business of making enterprises making better business decisions, I would like to share a few things about the real power of mathematics and its limitations. Knowing the boundaries, how to stretch them, and what to do outside of the realm of mathematical modeling is the real challenge.

Bio: Dr. Tardif has over 30 years of experience leveraging mathematics such as optimization, probability and statistics, decision sciences to business and technology problems. She graduated from McGill University with a BS in Math, obtained a Master of Math from the University of Waterloo, and obtained her PhD from Northwestern University. She has worked both in academia, consulted for high-tech business, and worked for software providers of supply chain planning and execution systems. But still is still learning something new every day! She lives in Pittsburgh with her husband and two children.

Title: Twin primes and their kin

Abstract: The question of whether there are infinitely many pairs of twin primes (prime numbers that differ by 2) has puzzled mathematicians for over 200 years. Until recently, it was not even known whether there are infinitely many pairs of primes that differ by a finite number. In 2013, Yitang Zhang stunned the mathematics community by proving that there are infinitely many pairs of primes that differ by at most 70,000,000. While 70,000,000 is still quite far from 2, Zhang's work has inspired a flurry of activity on this problem, giving reason to hope that a resolution to the Twin Primes Conjecture is within reach. In this talk, I will discuss the current state-of-affairs of the Twin Primes Conjecture and I will mention some of my own work on related problems.

**Title**: The Critical Role of Math in Flow Visualization Techniques** **

**Abstrac**t: At NASA Glenn Research Center, researchers and engineers are working on designing the next generation of air vehicles and their propulsion systems. As part of the design process, it is very important to understand how air flow passing over and around the vehicle’s engine affects its overall health and performance. The study of this air flow interaction is referred to as aerodynamics. Often times, the aerodynamics of a newly designed vehicle are studied in a wind tunnel where air flow, mimicking real flight conditions, is passed over a scaled model of the aircraft and/or a model of the aircraft’s engine. The air flow passing over the model is normally invisible to the human eye, however it is very useful to be able to “see” this air flow. Several flow visualization techniques exist in order to make the flow visible. One such technique is known as “schlieren” which is an optical method used to visualize the flow, based on light rays refracting through the flow’s density gradients. The presentation will not only go over the schileren technique, but will also give real-world examples of the technique and its sister techniques in use at NASA. In addition, a significant portion of the presentation will show how math plays a critical role in the implementation and understanding of these techniques and their results.

**When**: Thursday January 22nd, 2015 at 2:45pm

**Speaker**: Nguyet Nguyen, Department of Mathematics and Statistics, Youngstown State University

**Title**: Hidden Markov Models for Financial Economics

**Abstrac**t: Hidden Markov Models (HMMs) are typically used to predict hidden regimes of observation data. Therefore they are used in many different areas such as speech recognition systems, computational molecular biology, and financial economic predictions. In this talk we use HMMs for both single observation data and multiple observation data to predict regimes of some macro economics variables such as: Inflation (CPI), Economics Growth (GDP), Stock Market Index (S&P500) and Market Volatility (VIX). We use the variables to calibrate HMMs' parameters and then use HMMs with the obtained parameters to predict economics trends and stock prices. We also avoid overfitting by analyzing relationships between macro economics regimes and stock performance to make stock selections.

Refreshments will be served at 2:30pm.

**Title**: PDE-free variational imaging methods based on sparse representations** **

**Abstrac**t: Fourier analysis provides many elegant approaches to differential operators and related tools in PDE-based image processing. Replacing differential operators with the operators based on multiscale sparse representation systems (such as wavelets or composite wavelets, including shearlets), leads to the design of a brand new class of adaptively anisotropic operators. Those are not meant to approximate the differential operators, but rather to replace them in a variety of applied signal processing settings, such as diffuse interface approximations to the TV (total variation) functional in a variety of applications. Our ongoing research aims at merging the knowledge and experience of the applied harmonic analysis/sparse systems, compressive sensing and PDE communities to create qualitatively new and highly adaptable methods for image analysis and reconstruction.

Refreshments will be served at 3:20pm.

**Title**: From Hands-on to Mathematics to the International Space Station

**Abstrac**t: While attending UA I was a non-traditional student, working full-time and attending classes part-time. Early in my career as a NASA technician, I’d been afforded opportunities to grow and develop my craft; becoming a specialist in the area of micro-miniature techniques. Deciding to return to college to complete my degree was a surprise to my organization. Mathematics provided me a new skill, analytical thinking. I am now a power system analyst for the International Space Station.

Refreshments will be served at 3:20pm.

**Title**: Modeling Quasicrystals with Dynamical Systems: An Investigation of Periodicity and Quasiperiodicity

**Abstrac**t: The mathematical modeling of quasicrystals, whose discovery by Dan Shechtman earned him the 2011 Nobel Prize in Chemistry, is a fascinating problem that involves work in different areas of mathematics, and has applications to different areas of science. We are particularly interested in the symbolic dynamics on aperiodic sequences and tilings. In this talk, we trace a brief history of quasicrystals and discuss the surprising interplay between dynamical systems and mathematical physics.

Refreshments will be served at 3:20pm.
