    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

      Abstract: Ever want to create your own solar system? Now you can! In this workshop participants will be introduced to python scripting using a Linux environment with the goal of modeling an N-Body problem. Topics covered will included package management for the linux OS, importing python libraries, and basic scripting for numerical computation touching on classes, functions, and plotting data.
    3. Python II:
      3:30-5:00pm on October 16, in Stright 220
      Presenter: Dr. Ed Donley

      Abstract:  In this workshop, participants will learn some fundamental procedures for analyzing images and will implement those procedures in the Python programming language using popular Python packages.  Image processing tasks will include edge detection, line detection, and identification of objects within images.

      October 22, 2014
      Presenter: Dr. Pete Vanden Bosch
       Dr. Pete Vanden Bosch currently teaches math at Marymount University. Served in USAF 26 years, culminating as chief of analysis and science & technology advisor for USNORTHCOM and NORAD. Worked in a think tank on homeland security issues for three years. Taught high school 1977-84. Dr. Vanden Bosch has published articles on  mathematics education, nuclear effects, stochastic processes, military doctrine, homeland security, numerical estimation, and the psychology of decision making.

      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.

      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.

         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.
