Some student research projects
A Closer Look at Bobo's Sequence with Dan Clancy
Dan and I studied an integer sequence introduced by E. Ray Bobo in the article A Sequence Related to the Harmonic Series. Bobo posed several questions concerning the sequence; Dan and I answered them. Our research resulted in this paper. See sequences A103762 and A242679 in The On-Line Encyclopedia of Integer Sequences. (Dan won a 1st place in the 2011 Skyway STEM competition.)
Exceptional Bobo Numbers with Alan Mitchell and Sam Zandi
In the work with Dan Clancy described above, Dan and I found that some of the numbers in the sequence of Bobo numbers had an rather unusual property. These unusual Bobo numbers were called "exceptional," and we knew of only one exceptional Bobo number (namely, 36). Alan, Sam, and I took up the task of finding and describing all exceptional Bobo numbers. Our research resulted in a paper that has been submitted for publication (details available upon request). See sequence A277603 in The On-Line Encyclopedia of Integer Sequences.
Kimberling's Conjecture on Harmonic Numbers when Jointly Ordered with Logarithms with Gary Rathbone and Andrew Severs
Gary, Andrew, and I studied the sequence A206911 in The On-Line Encyclopedia of Integer Sequences. More details will be posted later. (This project won a 2nd place in the 2017 Skyway STEM competition.)
The Falling Ladder Paradox Revisited with Brittany Burke and Zach Jackson
The falling later problem is a famous related-rates problem that typically appears in Calculus 1. The standard related-rates approach to solving the problem leads to a physically unrealistic solution. Physically correct solutions are well known (but not in calculus classes). Brittany, Zach, and I actually performed some falling ladder experiments, analyzed the solution model, and provided some new details. Our work resulted in this paper (Preprint available here.)
Lovie Smith, NFL Coaches, and Separating Hyperplanes with Timothy Dannels, Nandjui Koutouan, and Reginald Thompson
We found a hyperplane in 7-dimensional space that best separated "winning" and "losing" NFL coaches. Lovie Smith falls on the losing side of our hyperplane. (This project won a 1st place in the 2013 Skyway STEM competition.)
Generating cycles of Newton's Method with Kevin Kuipers
Kevin studied the behavior of certain periodic cycles generated when Newton's method is applied to polynomials.
