Mathematical Modeling-based Engineering Education through an Axiomatic Design Approach
  Location: KFC Courts
  Date: Monday, Aug.1
  Time: 8:00 PM -8:45 PM

  Abstract: Many engineering students have difficulty resolving real life problems through traditional instruction. Most of them do not develop or apply the fundamental science-math knowledge to construct a functional understanding. A mathematical modeling learning approach named Axiomatic Design represents a didactical alternative to achieve not only the scientific skills but also the ability toward the design, creativity, and innovate of engineering processes based on an adaptive expertise for learning using mathematics and physics principles. We present an axiomatic design application in the context of a block stacking situation and the corresponding expected learning outcomes.

You Can Build a Scanning Tunneling Microscope for Your Classroom!
  Location: KFC Courts
  Date: Monday, Aug.1
  Time: 8:00 PM -8:45 PM
  Author: Mark Plano Clark, Doane College

  Co-Author(s): Paul Garcia , Axel Enders
  Abstract: Two years ago the authors proposed to produce a low-cost room-temperature atmospheric-pressure scanning tunneling microscope (STM) with atomic resolution -- to be accessible to high school and college teaching labs. Project costs are currently less than $200. The techniques to produce the STM require access to a basic machine shop and materials, and some skill in producing low-voltage (<20 V) amplifiers to drive the piezos. Each of the components make great student projects. Flat piezoceramic sheets are cut and then formed into rectangular structures to provide the x, y, and z scanning motions. We are using the open-source Gnome X Scanning Microscopy (GXSM) software and a commercial digital signal processing board but hope to produce a much cheaper digital signal processing board to further lower the cost.
