A Digital Hydraulic Valve, Actuated Using A Piezoelectric Linear Motor, Brian C. Bevill Jul 2011

A Digital Hydraulic Valve, Actuated Using A Piezoelectric Linear Motor, Brian C. Bevill

Purdue Polytechnic Directed Projects

Proportional control in hydraulics is widely utilized. The most widely used current types of proportional valves utilize solenoid technology. While this technology has been around for decades and has been proven an effective means of control, there is always a demand for improved performance of advancing technologies. Integrating piezoelectric devices as a means to control hydraulic systems helps advance control for hydraulic systems.

Piezoelectric stack devices have been used to control hydraulic systems with success. Advantages of these stacks include being relatively small with a high power to weight ratio, using less energy than solenoid operations, and being fast acting. …

Library Scholars Grant Presentation, Brent K. Jesiek

Library Scholars Grant Program

The primary goal of this project is to document the historical development of computer engineering as a distinct academic discipline and professional specialty in the United States, from the origins of the field in the 1940s to the early 2000s. My research is more specifically focused on three main contexts: a) the computer industry, b) professional organizations and sub-groups, and c) academic departments, degree programs, and curricula.


Assessing Pedagogy In Bioengineering Classrooms: Quantifying Elements Of The “How People Learn” Model Using The Vanth Observation System (Vos), Monica F. Cox, David S. Cordray Oct 2008

Assessing Pedagogy In Bioengineering Classrooms: Quantifying Elements Of The “How People Learn” Model Using The Vanth Observation System (Vos), Monica F. Cox, David S. Cordray

School of Engineering Education Faculty Publications

One goal of the VaNTH Engineering Research Center is to estimate the effects of the “value added” to bioengineering student learning as a result of “How People Learn” (HPL) framework interventions. A necessary step in that process is to assess pedagogical differences in both lecture-based and HPL-oriented courses. Data from 28 bioengineering courses, over five semesters, were analyzed using a newly developed HPL Index. This index, developed from the Classroom Interaction Observation portion of the VaNTH Observation System, reports levels of HPL-inspired pedagogy, traditional pedagogy, and classroom organization within a class using codes for different types of faculty and student …
