Rapid Prototyping In Design Education: A Comparative Study Of Rapid Prototyping And Traditional Model Construction, Scott D. Greenhalgh

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

To evaluate the effectiveness of a rapid prototyping into a curriculum, a study was conducted requiring students to conceive a design and create a model. Students were randomly selected to be given access to the rapid prototype or to create the models by hand. The students' models were evaluated on scale, design, and craftsmanship. Students participated in a survey consisting of perceptions of design feedback and difficulties as well as interests and affective traits. The study utilized qualitative data investigating the instructors' perceptions prior to implementing rapid prototyping into the curriculum and its correlation to observed events.

The study found …

Development Of A Model Predictive Controller For Tankless Water Heaters, Gregor P. Henze, David P. Yuill, Andrew H. Coward

David Yuill

This paper describes the development of a novel approach to temperature control of tankless water heaters (TWHs). Conventional methods of controlling TWHs typically allow a high degree of error in the outlet water temperature when subjected to disturbances in flow rate or inlet water temperature. Poor control affects comfort, safety, and energy consumption associ- ated with TWHs. The novel control approach presented here uses model predictive control (MPC) to minimize the outlet temperature error. A dynamic heat transfer model of an electric TWH is developed and validated and used within a MPC-based controller. The controller is interfaced to a physical …
