A Computational Analysis of the Fermi, Pasta, Ulam Paradox

This paper presents a computational study of the Fermi, Pasta, Ulam (FPU) paradox as it is applied to a system of nonlinear springs and thirty-two masses. The chain of springs and masses experiences motion only in one direction without the forces of friction or internal heating present to reduce the energy of the system. The program, written in Python, uses the Runge-Kutta method and Newtons second law for its calculations of motion.

Energy of a Two-Gas System

This paper presents a computational program designed to simulate a two-gas system in Visual Python. Similar to the well-known "Particles in a Box", this simulation aims to illustrate the energies of two initially separated gases of different temperatures as they mix together and proceed toward equilibrium.

The Zeeman Catastrophe Machine

Catastrophe theory states that for certain non-linear systems, small changes in the parameters may cause dramatic changes in the equilibrium. The problem is how to set the parameters such that one can examine the interesting behavior of the hypothetical situation. This paper examines the aspects of the chaotic Zeeman Catastrophe Machine, invented by Christopher Zeeman in 1969.

Thermodynamic Properties of Engine Cycles

The objective of this project was to create a model for three different types of engine cycles: Carnot Cycle, Otto Cycle, and Brayton Cycle. These models will simulate the different steps of each process and calculate the energy and work done. The models were all initially computed using hydrogen as a fuel source. Real data was then obtained that allowed the models to be adjusted to match more realistic situations.

H. A. Lorentz as the Grandfather of Quantum Physics

The first Solvay Conference in the fall of 1911 set a precedent for how leading physicists collaborate in order to solve difficult problems such as blackbody radiation and the photoelectric effect. By the end of the fifth Solvay Conference in 1927, the foundation had been laid for the theory of Quantum Mechanics. Besides featuring many prominent scientists in the field of quantum physics such as Einstein and Bohr, the first five Solvay Conferences had one very important characteristic that they all shared: they were chaired by Hendrik Lorentz. 


UD in the Community: Lamberti's Carries On Tradition

Its connection to UD helps the alumnus-owned Lamberti's fulfill its three pillars: local, tradition and famiglia. Lamberti's was the vendor for this year's Groundhog "Party in the Park" celebration; additionally, Lamberti's is looking into carrying Due Santi Rosso wine from UD's own vineyard on the Eugene Constantin Campus.

University of Dallas Dedicates Cardinal Farrell Hall -- Its New 'Front Door'

The University of Dallas community gathered on Friday, Feb. 2, 2018, for the formal blessing and opening of Cardinal Farrell Hall, named after our former bishop of Dallas, previous chancellor and longtime friend of the university, Kevin Cardinal Farrell. The opening of the new student-focused building marks the completion of one of several capital projects, a part of a broader institutional effort to transform the university's Irving campus.

Textile and Ceramic Exhibition Arrives from North Carolina Mountain Range

The Beatrice M. Haggerty Gallery proudly announces the opening of a two-person exhibition, "What Remains," featuring artists Rachel Meginnes and Assistant Professor of Ceramics Kelly O'Briant. The exhibition is curated by Penland Gallery Director Kathryn Gremley of the Penland School of Craft in North Carolina. In 2001, O'Briant received a two-year Core Fellowship from the Penland School of Craft, where Meginnes recently completed a three-year residency.
