AIChE National Student Competition
10/29/18: Logan Melican, 3rd Year Math & ChemE major - won the Third Place award for the National Student Paper Competition at the National AIChE conference in Pittsburgh for his talk: “Application of Asymptotic Approximants to Fluid Equations of State.” . 9 students who won from respective regional competitions around the country competed. Logan did his work in collaboration with Stephen Kronenberger, 3rd Year ChemE major, Nate Barlow, and Steve Weinstein.
Multidisciplinary effort leads to significant publication.
10/1/18: Ryne Beachley (B.S. Applied Math, 2018) and Morgan Mistysyn (Industrial & Systems Engineering, 4th year BS/ME student) were co-authors on a recent paper that enhanced our predictive ability for light deflection around black holes. The study began with Ryne during an NSF REU in the summer of 2017 at RIT, advised by Dr. Josh Faber. Ryne generated new coefficients for the weak-field limit of a Kerr black hole, and began exploring an extended parameter space that ultimately enabled the full trajectory of light around the black hole to be determined in closed-form. During the Fall of 2017, Drs. Nate Barlow and Steve Weinstein applied their method of asymptotic approximants to construct the closed-form expression, accurate to any order far from the black hole but only zeroth order in the limit as the black hole's critical radius (the radius below which light is absorbed) is approached. In the Spring of 2018, Morgan joined the team and developed a novel integral expansion method that enabled the approximant to retain accuracy to any order in this limit. The resulting closed-form expression is on the order of 10 times faster than alternative numerically-based methods and is thus a significant advance. The aricle can be foundhere.
Nate wins two teaching awards!

4/7/18: Logan Melican (2nd year APPMTH/ CHME-BS) & Stephen Kronenberger (2nd year CHME-BS) won the student presentation competition at the AIChE (American Institute of Chemical Engineers) Eckhardt Northeast Student Regional Conference!
The work involved the use of series expansions and the Gamma function to predict critical exponents that govern fluid phase behavior.
