Object Detection For Agricultural And Construction Environments Using An Ultrasonic Sensor, Joseph S. Dvorak, Marvin L. Stone, Kelvin P. Self
Biosystems and Agricultural Engineering Faculty Publications
This study tested an ultrasonic sensor‘s ability to detect several objects commonly encountered in outdoor agricultural or construction environments: a water jug, a sheet of oriented strand board (OSB), a metal fence post, a human model, a wooden fence post, a Dracaena plant, a juniper plant, and a dog model. Tests were performed with each target object at distances from 0.01 to 3 m. Five tests were performed with each object at each location, and the sensor‘s ability to detect the object during each test was categorized as "undetected," "intermittent," "incorrect distance," "good." Rigid objects that presented a larger surface …
Using Wii Technology And Experiential Learning To Teach Newtonian Mechanics To Rural Middle School Students, Joseph S. Dvorak, Tanya C. Franke-Dvorak, Shane Neel
Using Wii Technology And Experiential Learning To Teach Newtonian Mechanics To Rural Middle School Students, Joseph S. Dvorak, Tanya C. Franke-Dvorak, Shane Neel
Biosystems and Agricultural Engineering Faculty Publications
This study looked at the effects of an experiential learning activity using the accelerometer in the Wii Remote to teach basic concepts of Newtonian mechanics, e.g., acceleration, to middle school students in a rural school district. A major prerequisite for students at the mid-level in biosystems engineering programs is that they have a good knowledge of basic science, including physics. Education in these concepts must begin before college, such as at the middle school level. Improvements in science education are vitally necessary to achieve essential learning outcomes for middle school students in the U.S. and to prepare these students for …
