Horton, Constance Holden, Ken Wild University of Maine/National Park ServiceAbstractIn the spring term of 2004 twelve students and two faculty members at the University of Maine(UM) participated in a service learning project for the U. S. Virgin Islands National Park (thePark) on St. John. The Park archeologist sought to virtually preserve decaying sugar plantationbuildings using three dimensional computer-aided design (3D CAD) models with photographicskins. The challenges included fast turn-around time, student project management, andunforeseen technical

Simply stated, it encompasses the philosophy of workplace safetywherein there is a place for everything and everything is in its place – and it is kept that way.“Five S (5S) is a visually-oriented system of cleanliness, organization, and arrangement designedto facilitate greater productivity, safety, and quality. It provides a foundation for moreresponsible behavior on the job—better work, better products, better morale.” 3 Step 1: Sort The goal of Sort is to have a workspace with only the bare essentials required to do thetasks.

Scott Moor Indiana University-Purdue University Fort WayneAbstractProviding first-year students with a realistic engineering design experience is both difficult anddesirable. The benefits of hands-on projects to student learning and to student interest are welldocumented. However, it is a challenge to pose simple design problems that include bothengineering analysis and engineering synthesis. The construction of a wind chime provides anexcellent and yet quick engineering design problem for first-year

However, to test the hands-on component it hasbeen found to be necessary to use Competency Based Assessment (CBA).

accomplishing that outcome. Finally, again as othershave done, the committees went the extra step of requiring course chairs to develop sub-outcomes (e.g., course outcomes) that give explicit guidance to faculty about specific results thatare required in individual courses if the broader program outcome(s) are to be achieved. It isthese course outcomes that have taken on a central role in the quality control process.Course Outcomes In identifying course outcomes, the intent of the curriculum committees was to create a setof clear metrics by which course successes could be judged. Thus, it was essential that courseoutcomes be stated in clear terms and in a way that lent them to objective measurement. To thatend, course chairs were charged with

The figure shows two underdamped cases (α = 0.1 and0.707), one critically damped case (α=1), and one overdamped case (α=1.5). The least dampedcase clearly shows classic damped harmonic oscillation, where energy is being transferredbetween the inductor and the capacitor and slowly dissipated in the resistor, behavior identical tothe damped harmonic motion of the spring-mass-damper system of Figure 2.
