1. 3D Printer
   1:30-3:00 p.m. on September 12, in Stright 220
   Presenter: Dr. Brian Sharp and Dr. Ed Donley
   Abstract:Digital Fabrication and 3-D printing offer many possibilities to enhance the teaching and learning of mathematics by bridging the gap between the abstract and the concrete (or plastic as it may be). For example, calculus students often grapple with problems in which they have to find the surface area and volume of an object formed by rotating a curve around an axis. In the past, these types of problems usually remained abstract to students because the technology to create actual physical models was not available or convenient to use. With a digital fabrication facility, students can construct mathematical representations of the objects, send the representations to the 3D printer, and fabricate plastic models to investigate. Participants in this workshop will learn how to create models using Mathematica and a 3-D printer.
2. Python I:
   3:30-5:00 p.m. on October 9, in Stright 220

   a. 11:15 AM-12:05 PM, Weyandt 107
   Title: Variations on a Theme by Sierpinski
   Abstract:This talk will start by exploring a well-known fractal, the Sierpinski gasket. By using a stochastic version of the definition of this fractal, we'll come up with related fractals, like the one depicted here. You'll discover there's an interesting connection between these fractals and random walks.
   
   Excel Experiment: Sierpinski Sierpinski-Pascal
   
   b. 2:30 PM-3:20 PM, Weyandt 208
   Title: Analytical Career Paths in Government
   Abstract:There must be government jobs that need talented, quantitative folks, but what and where are they? And what do they really do? This talk will attempt to answer those questions. The focus will be on the author's own analytical career in government, but it will also offer some wider insights, based on his own exploration into those questions.

   Title: The Goldilocks Fallacy
   Abstract:When faced with a range of options, we often choose an intermediate one without much thought. This Goldilocks heuristic serves us well in many circumstances. In the presence of conflict, we seek compromise. We keep to the middle of our lanes when driving, without consciously reasoning why this is a really good idea. And when we see seven predictions for a hurricane's path, we intuitively assign higher likelihood to the intermediate predictions and less to the extremes, without consciously invoking the Law of Large Numbers. All of these mental shortcuts have some justification.

   But we also apply this Goldilocks heuristic in questionable ways. This presentation focuses on the idea that, in making choices when there are conflicting objectives - which are very common - choosing a middle path often fails to give you the best decision. In fact, sometimes it leads to the worst. We'll examine an analytic framework that allows us to quantify what "often" and "sometimes" really mean, and we'll also examine the psychological reasons that drive us to make these poor Goldilocks decisions.

3. Data Visualization Workshops
   February 27, 2015
   Presenter: Dr. Rafael E. Matos
   About the presenter:Dr. Matos was born in San Juan, Puerto Rico, and attended the University of Puerto Rico, where he obtained a Bachelor of Science degree in natural sciences. Upon graduation, he joined the US Navy and served as a surface warfare officer aboard to the USS GARCIA (FF 1040), the aircraft carrier USS AMERICA (CV 66) during Operations Desert Shield and Desert Storm, and was forward deployed on the USS CURTS (FFG 38) in Yokosuka, Japan.

Title: Building a Successful Company - With Mathematicians???
Abstract:
In this talk, Dr. Butler will give an overview of his company, Daniel H. Wagner, Associates, from
its historic beginnings in 1963 through its current role today. In 1963, Dr. Dan Wagner
founded his eponymous company with two guiding principles in mind. First, Dan believed in
hiring young mathematicians and training them to solve real-world problems. Second, Dan felt the quality of the writing in the technical reports and briefings provided to the clients was nearly as important as the technical content itself. To this end, and while the company size was small, Dan personally reviewed every scrap of paper that went out under the company name. Through the years, the company developed an impressive reputation for mathematical analysis applied to the budding field of Search Theory (find the lost H-bomb, find the sunken treasure, find the enemy submarine, etc.), and this continues to be an area of expertise today. At the same time, the company demonstrated the breadth of its capabilities by working in areas as diverse as DNA sequencing, retirement planning, crane anti-sway, speech recognition, speaker verification, and random number generation on GPUs.

Title:Decentralized and Autonomous Data Fusion Service (DADFS) for Heterogeneous
Unmanned Vehicles (UVs)
Abstract:
In a joint project with Johns Hopkins University Applied Physics Laboratory (JHU/APL), Daniel H. Wagner Associates developed a full-scale prototype Decentralized and Autonomous Data Fusion Service (DADFS) for heterogeneous Unmanned Vehicles (UVs) that obtains contact/track data from real-world UVs and (1) creates a Common Operational Picture (COP) on each UV node using sensor data from all communicating UV nodes and any other available relevant additional data; (2) synchronizes this COP across all UV nodes within the constraints of the available limited and intermittent communications links; and (3) (when human operators are available) provides alerts, requests for assistance, and the relevant COP information to UV operators in an intuitive, easily comprehended manner.

In this talk, we will discuss data fusion and a few of the various mathematical algorithms
required to successfully implement a Data Fusion Service. As a concrete example of the use of DADFS, the Office of Naval Research (ONR) conducted a demonstration of this first-of-its-kind technology, which will allow any unmanned surface vehicle (USV) to not only protect Navy ships, but also, for the first time, "swarm" offensively on hostile vessels.
