Automatic Assessment of the Design Quality of Python Programs with Personalized Feedback
J. Walker Orr, Nathaniel Russell
The assessment of program functionality can generally be accomplished with straight-forward unit tests. However, assessing the design quality of a program is a much more difficult…
Singular Points of High Multiplicity for Septic Curves
Nicholas J. Willis, David A. Weinberg
For real irreducible algebraic curves of the seventh degree, there are 22 types of singular points of multiplicity six, 174 types of singular points of multiplicity five, and at le…
Steady and Stable: Numerical Investigations of Nonlinear Partial Differential Equations
R. Corban Harwood
A nonlinear partial differential equation is a nonlinear relationship between an unknown function and how it changes due to two or more input variables. A numerical method reduces…
Oscillation-free method for semilinear diffusion equations under noisy initial conditions
R. C. Harwood, Likun Zhang, V. S. Manoranjan
Noise in initial conditions from measurement errors can create unwanted oscillations which propagate in numerical solutions. We present a technique of prohibiting such oscillation…
Interpreting Ulysses data using inverse scattering theory: Oblique Alfvén waves
Harry R. Wheeler, M. A. Reynolds, R. L. Hamilton
Solitary wave structures observed by the Ulysses spacecraft in the solar wind were analyzed using both inverse scattering theory as well as direct numerical integration of the deri…
Singular Points of Reducible Sextic Curves
David A. Weinberg, Nicholas J. Willis
There are 106 individual types of singular points for reducible complex sextic curves.
