Development Of A Problem-Based Learning (Pbl) And Cooperative Learning (Cl) Transportation Engineering Course For Undergraduate Students, Deogratias Eustace

Civil and Environmental Engineering and Engineering Mechanics Faculty Publications

This study reports the findings of a project that was done during the implementation of a problem-based learning (PBL) and cooperative learning (CL) elements into an undergraduate transportation engineering course. The study procedure used the student course evaluations, including a survey questionnaire, and university-wide standardized student evaluations. Additionally, student homework, tests, and exam grades were used as part of the evaluation process. Two methods of teaching formats were evaluated: the traditional teaching method of lecturing and using end-of-chapter book questions for homework assignments and the new currently used teaching method of student field data collection, preparation of a lab report …

Facilitating Use Of The Odor Footprint Tool By Nebraska Pork Producers, Rick R. Stowell

Department of Agricultural and Biological Systems Engineering: Faculty Publications

The goal of this project was to make Odor Footprint Tool (OFT) resources readily usable by pork producers and their technical advisors as a planning and screening tool when siting swine facilities. Detailed odor footprints for five specified sizes of swine facilities were developed for twenty-four locations throughout Nebraska: six regional sites and three “localized” sites within each region. Each odor footprint shows the predicted odor annoyance-free frequency as a function of the distance from the facility. Footprints developed using localized weather data differed only slightly from footprints produced using weather data from a regional site when the general topography …

Implementing Mass Nutrient Balance Procedures On Swine Production Facilities, Richard Koelsch, Alan Sutton

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Whole Farm Nutrient Balance (WFNB) approaches have been used to provide a measure of environmental performance (Aarts et al., 1992; Lanyon and Beegle, 1993; Klausner, 1995). Whole farm balance concepts are used as part of the Netherlands Mineral Accounting System public policy that includes compulsory mineral input and output reports from livestock farms and levies for excess imbalances (Jongbloed and Lenis, 1998). Procedures for measuring WFNB will be followed in measurements made on commercial swine facilities for 2006 and 2007. The conclusions developed based upon data from 13 for 2006 include:

• On average, the participating swine producers import 1.5 units …

System And Method For Analyzing Material Properties Using Hyperspectral Imaging, Jeyamkondan Subbiah, Chris Richard Calkins, Ashok Samal

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Systems and methods are provided for analyzing material properties of an object using hyperspectral imaging. An exemplary method includes obtaining a hyperspectral image of an object; analyzing the hyperspectral image according to an algorithm; and correlating data obtained from the analysis with material properties of the object.

Lipid Productivity Of Algae Grown On Dairy Wastewater As A Possible Feedstock For Biodiesel, Ian C. Woertz

Master's Theses

The objective of this thesis is to develop a biological wastewater treatment system that utilizes algal growth to simultaneously create renewable energy in the form of biodiesel and digester biogas, remove polluting nutrients, and abate greenhouse gases. Research under the Department of Energy Aquatic Species Program during 1978-1996 concluded that cultivating algae for biofuels was cost prohibitive at that time and that an integrated approach should be studied that combined wastewater treatment with algal biofuel production. Nutrient removal, in particular nitrogen and phosphorus, from wastewater is a growing regulatory need and the use of algae cultivation could create a unique …

Exceed Teaching Workshop: Tenth Year Anniversary, Allen Estes, Ronald Welch, Stephen Ressler, Norman Dennis, Debra Larson, Carol Considine, Tonya Nilsson, Jim O'Brien, Thomas Lenox

Engineering Technology Faculty Publications

In response to the need for faculty training, the American Society of Civil Engineers developed and funded the ExCEEd (Excellence in Civil Engineering Education) Teaching Workshop that is today - the summer of 2008 - celebrating its tenth year of existence. For the past decade, nineteen ExCEEd Teaching Workshops (ETW) have been held at the United States Military Academy, the University of Arkansas, and Northern Arizona University, with two more workshops scheduled for this summer for a total of 21 offerings. ETW has realized 449 graduates from 203 different U.S. and international colleges and universities. This paper summarizes the content …
