Mathematics and Computer Science Colloquium
Title: 
Casino Carnival Games: Past, Present, and Future

Speaker:  Mark Bollman
Professor of Mathematics
Mathematics and Computer Science
Albion College
Albion, MI

Abstract: 
Beyond the "big four" casino table games of baccarat, blackjack, craps, and roulette, over 1000 different games have been designed, proposed for casino use, and approved by the state of Nevada. In this presentation, we shall look at the math behind some of the games that have fallen by the wayside and at the mathematical issues that arise in designing a new game of chance. An opportunity to investigate the mathematics behind a new game proposal will be announced.

Planning for Graduate Study in Mathematics and Computer Science

Speaker:  David A. Reimann
Professor
Mathematics and Computer Science
Albion College
Albion, Michigan

Abstract: 
A degree in mathematics or computer science is excellent preparation for graduate school in areas such as mathematics, statistics, computer science, engineering, finance, and law. Come learn about graduate school and options you will have to further your education after graduation.

Title: 
Reducibility and Balanced Intransitive Dice

Speaker:  Michael Ivanitskiy^{1} and Michael A. Jones^{2}
^{1}University of Michigan; ^{2}Mathematical Reviews
Ann Arbor, MI

Abstract: 
We will review some results about balanced intransitive $n$sided dice and what it means for a set of dice to be reducible based on a concatenation operation. Using data from the Online Encyclopedia of Integer Sequences, the lexicographical ordering of dice, and permutations, we are able to construct new integer sequences representing the number of $n$sided reducible and irreducible dice. We define a notion of margin and explain how margins are effected by concatenation. We introduce a new splicing operation that generalizes concatenation and give conditions for when the resulting dice are balanced and irreducible. Finally, we construct new integer sequences for the number of fair, balanced dice and the largest margins for $n$sided, balanced intransitive dice.
Bonus: You will either get to make or will be given a set of balanced, intransitive dice.

Title: 
MultiLens Analysis of Office Dynamics and
Space Usage

Speaker:  Angela Morrison, '17
Graduate Student
Mathematics
Michigan State University
East Lansing, Michigan

Abstract: 
Workplace optimization is critical for organizations to make the most of their real estate as well as help employees stay more productive at work. Steelcase Space Analytics equips organizations with tools and data needed to measure and improve the effectiveness of the workplace by applying their proprietary sensing capability. This project aims to analyze office space dynamics and usage by investigating correlations between and within sensing and survey datasets sourced from Steelcase's 2 West (2W) facility. The data consists of sensor output that describes how often spaces are in use, as well as survey data that reports how the 2W employees feel about using certain spaces. Clustering analysis was developed to study the hidden trends of the sensor data and generalized linear mixed model (GLLM) was constructed to investigate the correlations between the sensor data and space traits data. The results showed that the significant space traits indicated by the GLMM were also the popular ones from survey data analysis.

Title: 
Spherical Panoramic Photographic Polyhedra

Speaker:  David A. Reimann
Professor
Mathematics and
Computer Science
Albion College
Albion, Michigan

Abstract: 
Conventional cameras view a small solid angle, limiting the both the field of view and projective distortion. However, multiple individual pictures are need to have full spherical coverage.
Cameras that can directly take spherical panoramic photos, such as the Ricoh Theta~S, have become available as relatively inexpensive consumer products.
Unlike a traditional camera, this camera has two hemispherical lenses, allowing it to see simultaneously in every direction around the camera.
These cameras produce an equirectangular projection, where each latitude row has the same number of pixels, which has severe distortion at the poles.
One approach to hardcopy display is to map the image onto the surface of a small polyhedron, such as a Platonic or Archimedean solid, which reduces the distortion.
Using such polyhedra resembles the process artist Dick Termes uses for painting on a sphere, which he calls a Termesphere. These techniques force the viewer to
see the world insideout.
This work maps the spherical photo to the inside of a large polyhedra to create a miniature pavilion which can be entered for a personal panoramic experience.
Other interesting applications and issues will be discussed.

Mathematics and Computer Science Colloquium
Title: 
The Geometry of Polynomials

Speaker:  Matt Boelkins
Professor of Mathematics, Grand Valley State University
Mathematics
Grand Valley State University
Allendale, MI

Abstract: 
In the geometry of polynomials, we seek to understand relationships among certain sets connected to polynomial functions. For example, Marden's Theorem reveals stunning connections between the critical numbers of a cubic polynomial with complex zeros and the inscribed inellipse of the triangle whose vertices are the polynomial's zeros.
In this talk, we'll discuss several important historical results from the geometry of polynomials and survey developments in the past 25 years that are centered on polynomial rootdragging, the study of how continuously changing one or more roots of a polynomial function affects various properties of the function. We will encounter some surprising structural results about polynomial functions that deserve to be more wellknown and also see beautiful interplay between calculus and Euclidean geometry.
