John E. Hammett III, St. Peter's University - "Accessing Mathematics Through Poetry: Engaging Learners at All Levels"

Mathematical poetry in its various forms foster opportunities; students can solve problems, investigate content, explore the history of mathematics, explain algorithms and other techniques, engage in recreational mathematics, and enjoy the beauty inherent in the discipline. Math poems can offer differentiated access points to mathematical content for learners of all ability, interest and preparation levels, including majors, minors, pre-service teachers, and general education students. All students and faculty are welcome and encouraged to attend this workshop; come prepared to help compose at least one math poem, either individually or as part of a small group, your choice. You will leave a math poet.

Mathematics/Computer Science Colloquium Series (co-sponsored by Lectures and Forum & Public Health):

Armin Mikler, University of North Texas - "RE-PLAN: A Framework for Responding to Biochemical Emergencies"

Emergencies stemming from the release of harmful biochemical substances demand a timely response. Therefore, local governments are required to maintain functional plans for receiving medical countermeasures (MCMs) from the Strategic National Stockpile (SNS) and distributing them within federally-mandated timeframes.

Determining optimal placement of clinics for the distribution of MCMs, requires the integration of geographic, demographic, and transportation data. The design and analysis of these response plans is a complex task. To this end, the RE-PLAN Framework has been developed to facilitate a data-driven response plan design. This talk will provide the highlights of RE-PLAN, a computational framework for placing facilities based on different optimization criteria.

Mathematics/Computer Science Colloquium Series:

Gwyn Whieldon (Mathematics), Hood College - "OCR and Bayesian Networks"

Bayesian networks are used to model real-world situations--with applications ranging from diagnosing illnesses based on symptoms, to predicting likelihood of passing on a given trait to ones' offspring, to identifying objects in an image. A neat application of these "probabilistic graphical models" is optical character recognition (OCR). OCR takes an image of printed (or even handwritten) text as input, and outputs the content of the text. This is widely used to scan images of printed text (as in Project Gutenberg and the Google Books project) and output eBooks which can be stored more compactly, indexed and searched, and be read or translated by machines. In fact, the US Postal Service has been using OCR since 1965 to pre-sort mail, as has the popular magazine Reader's Digest. This talk will detail some of the theory behind optical character recognition and will include a demonstration of several working OCR systems (as well as talking about how we could build our own from scratch!).

March 13

Mathematics/Computer Science Colloquium Series:

Dr. Kathleen Ryan, DeSales University - "Forget Yellow: Follow the Properly Colored Brick Road Instead"

We say an edge-colored graph is properly connected if there exists a properly colored path between every pair of vertices. In any such graph, we can reconsider the notions of distance and diameter by requiring that only properly colored paths are traversable. (Sorry, Dorothy: The yellow brick road is thus closed for travel!) In this talk, we define proper distance and proper diameter and we explore bounds on these quantities for various graph families.
