Feedback Applications In Active Noise Control For Small Axial Cooling Fans, Matthew J. Green
Feedback Applications In Active Noise Control For Small Axial Cooling Fans, Matthew J. Green
Theses and Dissertations
Feedback active noise control (ANC) has been applied as a means of attenuating broadband noise from a small axial cooling fan. Such fans are used to maintain thermal stability inside of computers, projectors, and other office equipment and home appliances. The type of low-level noise radiated from axial cooling fans has been classified as harmful to productivity and human well being. Previous research has successfully implemented feed-forward ANC, targeting specific narrow-band fan noise content related to the blade passage frequency (BPF) of the fan. The reference signal required for a feed-forward algorithm limits its ability to attenuate much of the …

Teaching Writing Through Peer Revising And Reviewing, Kristi Lundstrom
Theses and Dissertations
Although peer review, in which students evaluate each others' papers, has been shown to be beneficial in many writing classrooms, the benefits of peer review to the reviewer, or the student giving the feedback, has not been thoroughly investigated in the field of second language (L2) writing. The purpose of this study is to determine which is more beneficial to improving student writing: receiving or giving peer feedback. The study was conducted at the English Language Center (ELC) at Brigham Young University (BYU). Ninety-one students in nine writing classes at two different proficiency levels, high beginning and high intermediate, participated …
Active Learning In A Large Enrollment Introductory Biology Class: Problem Solving, Formative Feedback, And Teaching As Learning, Diane Flint Robison
Active Learning In A Large Enrollment Introductory Biology Class: Problem Solving, Formative Feedback, And Teaching As Learning, Diane Flint Robison
Theses and Dissertations
The purpose of this study was to take a case study approach to exploring student learning experiences in a large enrollment introductory biology class. Traditionally such classes are taught through the lecture method with limited instructor-student interaction and minimal student-centered learning (Lewis & Woodward, 1984; Wulff, Nyquist, & Abbott, 1987). Biology 120 taught at Brigham Young University winter semester 2006 by John Bell was chosen as the case for the study due to its large enrollment (263) and its innovative pedagogy. In the classroom, students applied their learning through a variety of student-centered activities including solving problems, discussing concepts with …
