A Simple Leapfrog Integration Scheme to Find Optimal Interplanetary Trajectories

Creator:: Kelley, Scott M.
Abstract:: The calculation of interplanetary trajectories is a numeric problem which requires a high degree of precision for the results to be accurate. A computer program was written for this project which uses leapfrog integration combined with Newton’s method of iterative root finding to find ideal interplanetary trajectories. Reasonable initial conditions...

Practical Mechanically Interlocked Molecules: A Model of Gas Adsorption in Metal OrganicFrameworks Harboring Rotaxane Molecular Shuttles

Creator:: Carney, Jonathan
Abstract:: Metal organic frameworks(MOFs) are a class of crystalline materials utilized in gas storage, chemicalsensing, and other engineering applications. Recently chemists have begun synthesizing MOFs withmoving parts in order to further these applications. A wide array of dynamic MOFs have been created andtheorized. Among them is the interlocking of a ring...

A Study of Charging Behaviors in Organic Semiconductors using Optical Trapping

Creator:: Founds, Graham M.
Abstract:: We measure the charging and discharging of two organic materials, PCBM and ADT-TES-F. These materials are studied through the noncontact method of particle trapping known as Optical Tweezers, where an IR laser is used to constrain the motion of a coated or noncoated silica sphere while its positional data is...

Fabrication and low-temperature measurement of quantum devices

Creator:: Nichols, Dublin M.
Abstract:: Since the advent of graphene, research on 2D materials has exploded. Countless experiments have uncovered novel properties that emerge when different layered crystals are cleaved down to only a few atomic layers in thickness. The most popular of these non-graphene 2D materials is MoS2, a semiconductor which has been of...

Riesz Transforms on a Sphere

Creator:: Tyma, Troy
Abstract:: Motivated by the Navier-Stokes equations, which are a set of unsolved equations related to fluid motion in R^3, we explored the incompressibility condition and the Neumann boundary problem. After exploring, we noticed that using iterated Riesz transforms of the boundary data could be used to get information about the velocity...

Exploiting Diffraction Orders from a Phase Limited SLM to Remove and Model Zernike Aberrations

Creator:: Goschie, Aaron J.
Abstract:: Using a plastic bottle, we explore the capabilities of a reflective phase-only Spatial Light Modulator (SLM) in removing wavefront aberrations using a Zernike polynomial phase mask, with the modulators phase depth limited to 0.8π radians. Wavefront aberrations, which can be modeled with Zernike polynomials, distort image transmission through various optical...

Freezing a Softly Repulsive Fluid : Monte Carlo Methods and the Weeks-Chandler-Andersen Potential

Creator:: May, Christopher
Abstract:: The equation of state for a fluid described by the Weeks-Chandler-Andersen (WCA) potential was solved to determine at what pressures and temperatures the fluid will theoretically freeze. A Monte Carlo (MC) algorithm was used to sample a system of 256 spheres for a set of thermodynamic averages to locate and...

A Generalized Scheme for Creating Regge Calculus Models of General Relativity

Creator:: Hanson, Ben R.
Abstract:: Solutions to Einstein's equations are usually found by considering ideal, simplified models. However, if the real world always matched ideal physics models, then farmers would milk black and white spheres. To combat this, Regge calculus was developed as a numerical approximation scheme for general relativity. In Regge calculus curved manifolds...

Simulating the Dynein Motor Protein: A Monte Carlo Approach to Achieve Coordinated Stepping

Creator:: Kiatvongcharoen, Jin
Abstract:: The motor protein dynein is responsible for cellular processes such as axonal transport and cell division by delivering vital information along the microtubule track. A failed delivery can cause severe damage to the cell’s functionality and lead to neurological diseases. Despite dynein’s rich history in cellular research, the mechanism of...

Drunken Walking: A Novel Brownian Dynamics Simulation for the Mechanochemical Cycle of the Dynein Motor Protein

Creator:: Waczak, John L.
Abstract:: The dynein molecule is a peculiar motor protein recognized for its unique stepping behavior. Sometimes it steps forwards. Other times it steps backwards. It has even been observed to occasionally shuffle by beginning a step with the same domain many times in row. These motions make dynein an interesting object...
