When: November 9, 2011, 11:30am-12:30pm Where: Olin Hall, Room 320 We will screen a video of Dr. David A. Ferrucci’s keynote address, “IBM’s Watson/DeepQA,” which he gave at the 2011 Federated Computing Research Conference. (QA stands for “Question Answering.”) Ferrucci is an excellent speaker and provides an explanation of how his group at IBM tackled…

When: November 2, 2011, 11:30am-12:30pm Where: Olin Hall, Room 320 Presenter: Prof. Mat Timm of Bradley University A graph is collection of dots, called vertices, with some pairs of vertices joined together by line segments, called edges. A graph is a weighted graph when each end of each edge is labeled with an integer. Each…

When: Wednesday, October 19, 11:30am – 12:20pm Where: Olin Hall 320 Presenter: Max Hailperin Minnesota law provides for publicly-funded recounts of close elections. This raises the question of what exactly constitutes a “close election.” Is the current standard appropriate? Two recent high-profile statewide recounts have drawn considerable attention to this question, though in fact multiple…

When: Thursday, October 13, 4:30pm – 5:20pm Where: Olin Hall 320 Presenter: Jim Walsh, Professor of Mathematics, Oberlin College In this talk the dynamics of a simple model of three charged bodies interacting under an inverse square electrostatic force is presented.  Professor Walsh will illustrate the manner in which fractals and chaos arise in the…

Second-Order Linear Differential Equations and Integrating Factors, Part 2 When: Wed, September 28, 11:30am – 12:20pm Where: Olin Hall 320 Presenter: Ron Rietz For first-order linear differential equations, a simple routine determines an integrating factor which leads to an integral expression giving all of the solutions of the equation. For second-order linear differential equations there…
