The Global Relevance Of Bio-Based Industries To Engineering And Technology Education, Kurt A. Rosentrater, Radha Balamuralikrishma Jun 2006

The Global Relevance Of Bio-Based Industries To Engineering And Technology Education, Kurt A. Rosentrater, Radha Balamuralikrishma

Kurt A. Rosentrater

The society in which we live has developed an insatiable demand for energy and material goods. In particular, recent data reveals that the aggressive pursuit of improved standards of living in the highly populated countries of India and China has contributed to increased demand for fossil fuels, which has exacerbated the recent spike in energy costs. Historically, these needs have been met primarily by fossil fuels and other non-renewable raw materials. As environmental concerns grow, however, renewable resources are gaining increased attention. This paper examines the emergence and importance that bio-based industries are increasingly beginning to play. A bio-based enterprise ...


An Evaluation Of An Established Case Study For Engineering Technology Education, Kurt A. Rosentrater, Radha Balamuralikrishma Jun 2006

An Evaluation Of An Established Case Study For Engineering Technology Education, Kurt A. Rosentrater, Radha Balamuralikrishma

Kurt A. Rosentrater

Engineering and technology educators focus on meeting existing and future needs of industry when designing the content domain and planning instructional methods in their discipline. However, undergraduate students in engineering and technology rarely have an opportunity to solve real world problems that require integration across several disciplinary branches of engineering and those outside of engineering. This makes it difficult for students to make the transition from academia to industry especially in an era where the principles of concurrent engineering are employed in new product design and development. Therefore, there is a strong need to bring challenging, industry involved problems into ...


Biorefining Of Renewable Resources—Emerging Opportunities For Engineering Education, Kurt A. Rosentrater Jun 2006

Biorefining Of Renewable Resources—Emerging Opportunities For Engineering Education, Kurt A. Rosentrater

Kurt A. Rosentrater

The society in which we live has developed an insatiable demand for energy and material goods. Historically these needs have primarily been met by utilizing fossil fuels and other nonrenewable raw materials. As environmental concerns grow, however, renewable resources are gaining increased attention. This paper examines industrial biorefineries, which are at the leading edge of the development of emerging biobased industries. Biorefineries, similar in concept to traditional petroleum refineries, utilize various conversion technologies to produce multiple products, including fuels, chemicals, industrial products, and electrical power from renewable biomass sources, such as corn stover, residue straw, perennial grasses, legumes, and other ...


Preparing New Faculty Members To Be Successful: A No-Brainer And Yet A Radical Concept, Rebecca Brent, Sarah A. Rajala, Richard M. Felder Jun 2006

Preparing New Faculty Members To Be Successful: A No-Brainer And Yet A Radical Concept, Rebecca Brent, Sarah A. Rajala, Richard M. Felder

Sarah A. Rajala

A multifaceted program at North Carolina State University involving workshops and mentorships helps prepare new faculty members and graduate students for successful academic careers. This paper describes the elements of the program, reviews assessment data for each element, and offers recommendations to engineering schools wishing to establish their own programs for new and future faculty members.


Updating Mechanical Engineering Measurements And Instrumentation—A Case Study, Theodore J. Heindel Jun 2006

Updating Mechanical Engineering Measurements And Instrumentation—A Case Study, Theodore J. Heindel

Mechanical Engineering Conference Presentations, Papers, and Proceedings

Measurement and instrumentation is a common course topic in many undergraduate mechanical engineering curricula. This paper summarizes changes to ME 370 – Engineering Measurements and Instrumentation at Iowa State University (ISU), which went through major course revisions from fall 2003 to spring 2005. Modifications to the course include the following: (i) incorporating virtual measurements and instrumentation into the lecture and laboratory, (ii) coupling the lecture and laboratory more closely through an on-line course manual, (iii) providing additional course resources through WebCT to enhance student learning, and (iv) updating and/or developing several new laboratory exercises to demonstrate key course learning objectives ...


Demonstrating Electromagnetic Noise In An Undergraduate Measurement And Instrumentation Course, David Muff, Theodore J. Heindel, Sriram Sundararajan Jun 2006

Demonstrating Electromagnetic Noise In An Undergraduate Measurement And Instrumentation Course, David Muff, Theodore J. Heindel, Sriram Sundararajan

Mechanical Engineering Conference Presentations, Papers, and Proceedings

Electromagnetic noise (interference) is always present in a measurement system. The desire to minimize noise in your signal of interest can only be accomplished after the noise is properly identified. This paper summarizes a mechanical engineering undergraduate laboratory activity developed for ME 370 – Engineering Measurements and Instrumentation at Iowa State University. The goals of this activity are to (i) develop an understanding of how analog noise enters a measurement system and (ii) investigate several noise reduction methods. Students induce and measure capacitively coupled noise and investigate how the noise is related to noise source frequency and measurement circuit resistance. Methods ...


Home Schoolers In An Engineering/Education K12 Outreach Program, Lawrence Genalo, Jamie Gilchrist Jan 2006

Home Schoolers In An Engineering/Education K12 Outreach Program, Lawrence Genalo, Jamie Gilchrist

Materials Science and Engineering Conference Papers, Posters and Presentations

The Toying With TechnologySM program (TWT) has been offered to preservice elementary and secondary teachers for ten years. This program is designed to explain the principles behind many of the technological innovations in wide use today. This is accomplished through hands-on laboratory experiences. This includes, but is not limited to, experiences with programming, global positioning systems, and biomedical engineering. This program uses engineering as a basis to teach math, science, technology and problem solving concepts.

This paper will describe the twelve week experience of a home schooled group engaged in the TWT program. Home schooling is a growing trend in ...


Communication Practices Of Women In Undergraduate Engineering Classes , Sarah Michelle Brown Jan 2006

Communication Practices Of Women In Undergraduate Engineering Classes , Sarah Michelle Brown

Retrospective Theses and Dissertations

Communication Practices of Women in Undergraduate Engineering Classes explores ways in which women and men communicate in undergraduate engineering classes and ways to better attract and retain women in engineering programs. The data, gathered over three semesters, include classroom observations, surveys, and interviews. Seven classes were analyzed: four in engineering, two in history, and one in food science. This thesis brings together three articles written for various academic audiences: engineering education, leadership, and women's studies. The individual articles focused on (1) class participation, leadership, and negative behavior in undergraduate engineering classes, (2) leadership styles of women and men, and ...
