The Uiuc Virtual Spectrometer: A Java-Based Collaborative Learning Environment, Michael C. Dorneich, Patricia M. Jones Oct 2001

The Uiuc Virtual Spectrometer: A Java-Based Collaborative Learning Environment, Michael C. Dorneich, Patricia M. Jones

Michael C. Dorneich

The development of the UIUC Virtual Spectrometer (UIUC-VS), an interactive, Java-based simulation and tutoring system, is discussed. The apprenticeship model oflearning is utilized to create a learning environment for the study of a one-dimensional proton nuclear magnetic resonance (NMR) experiment, with the goal of linking theoretical knowledge with practical operational experience. Active, exploratory, apprentice-style learning is supported via modes of operation within the system. Students can flexibly choose to "observe the expert" perform and explain operational steps, or "act as an apprentice" and carry out the steps autonomously. Students can switch between modes at their discretion, giving them control of ...

A new two-semester capstone senior design course sequence in the area of assistive technology has been developed and integrated within the established curriculum of the Department of Mechanical and Industrial Engineering (MIE) at the University of Massachusetts (UMass) Amherst. Entitled “Senior Design Projects to Aid the Disabled,” the capstone sequence includes close collaborations with the Lemelson Assistive Technology Development Center (LATDC) at Hampshire College and Adaptive Design Services (ADS) under the Massachusetts Department of Mental Retardation (DMR). The new design course allows students to work directly with collaborators and disabled clients to solve specific assistive technology design problems. Through these ...


Entrance Capacity Of An Automated Highway System, Randolph W. Hall, Ali Nowroozi, Jacob Tsao Jan 2001

Entrance Capacity Of An Automated Highway System, Randolph W. Hall, Ali Nowroozi, Jacob Tsao

H.-S. Jacob Tsao

This paper evaluates the entrance capacity and queueing delay for Automated Highway Systems through use of simulations and analytical modeling. Queueing statistics are also used to determine the sustainable capacity of alternative concepts, taking trip length distribution and spacing between ramps into consideration. Based on safety-spacing headways (produced in a separate analysis), the most promising concept utilizes platoons both on the highway and on on-ramps. However, it is unclear whether comparable capacity can be achieved on exit, when vehicles must be decoupled from their platoons, and whether it is safe for vehicles to enter the highway in closely spaced platoons ...


Virtual Classroom For Teaching The Economics Of Engineering Design, Janis P. Terpenny, Kimberly Sward Jan 2001

Virtual Classroom For Teaching The Economics Of Engineering Design, Janis P. Terpenny, Kimberly Sward

Janis P. Terpenny

As decision-makers, engineers must be knowledgeable and competent in multiple aspects of design. Engineering is more than a problem solving activity focusing on simply the expected performance of designed artifacts. Consideration must also be given to the economic consequences of design decisions on life-cycle issues. A major challenge to undergraduate engineering education is to increase student competency in the economic elements that are such a critical part of the engineering process. Many believe that success in this endeavor requires new methods and materials that actively engage students in learning, are more closely aligned with engineering decision-making, and include real-world problems ...
