Setting Empirically Informed Policy Benchmarks For Physical Science Teaching, Elizabeth B. Lewis, Ana Rivero, Lyrica L. Lucas, Aaron Musson, Brandon Helding

Department of Teaching, Learning, and Teacher Education: Faculty Publications

In the United States, research on beginning science teachers provides little guidance regarding empirical minimum levels of discipline-specific science coursework for sufficient subject matter knowledge to teach science. Accordingly, in this study we analyzed secondary physical science teachers' science coursework for subject matter knowledge (SMK) and resulting misconceptions of chemistry and physics concepts. Findings were compared with state-level science teacher certification policies. Participants had either: (a) completed a master's level teacher preparation program with an undergraduate degree in science, (b) completed an undergraduate teacher preparation program with a minor degree or more in science, or (c) were undergraduate students enrolled …

Assessment Of Students’ Levels Of Studying Physics, Fozil Irmatov

Mental Enlightenment Scientific-Methodological Journal

This article explores the specifics of teaching physics in nonphysical specializations. In the areas of non-physical specialization of pedagogical higher education institutions, it is emphasized that the physics program should be radically different from the curriculum of physics, which is a specialized subject. Many other modern educational technologies are based on the teaching of physics for students of non-physical specialties, the organization of the educational process. The main focus in the teaching of physics to students of non-physical specialties is the content of theoretical materials necessary for the formation of scientific thinking among students, the creation of opportunities for independent …

Environmental Topics In Physics By Inquiry Course: Integration Models Used By Physics Teachers, David A. Kimori, Gillian Roehrig

The Qualitative Report

As we approach the second quarter of the twenty-first century, one may predict the environment will be among the dominant themes in political and educational discourse. This study investigates how three physics teachers integrated environmental topics and issues in their classroom. Data collection methods including field notes taken from observations, teachers’ interviews, and a collection of artifacts and documents were used. The data were coded, analyzed, and organized into categories utilizing Fogarty’s models of curriculum integration. Findings of this study indicate teachers acknowledge the importance of teaching environmental issues in their classrooms; however, implementing and utilizing effective integration strategies and …

Energetics Of Biological Mechanics And Dynamics, Daniel Seara

Yale Graduate School of Arts and Sciences Dissertations

Living matter is a class of soft matter systems that maintains itself away from thermodynamic equilibrium by the continual consumption of chemical energy. Indi- vidual proteins consume energy and break detailed balance to drive active force generation by molecular motors, force-dependent binding kinetics, and chemically driven (dis)assembly. These non-equilibrium dynamics propagate across heterogeneous structures to drive essential life processes such as replication, migration, and shape change at the scale of both single cells and multicellular tissues. While much work has been done to understand the molecular processes underlying each individual non-equilibrium behaviors, we lack a general understanding of how the …

Error-Corrected Quantum Metrology, Sisi Zhou

Yale Graduate School of Arts and Sciences Dissertations

Quantum metrology, which studies parameter estimation in quantum systems, has many applications in science and technology ranging from frequency spectroscopy to gravitational wave detection. Quantum mechanics imposes a fundamental limit on the estimation precision, called the Heisenberg limit (HL), which bears a quadratic enhancement over the standard quantum limit (SQL) determined by classical statistics. The HL is achievable in ideal quantum devices, but is not always achievable in presence of noise. Quantum error correction (QEC), as a standard tool in quantum information science to combat the effect of noise, was considered as a candidate to enhance quantum metrology in noisy …

College of Sciences Posters

In the modern SRF research, Thin films coated niobium cavities are used for the low cost and increased quality factor. Among the potential thin film materials applied on the niobium, performances demonstrated by the Nb3Sn cavities makes this material attractive for SRF accelerator applications giving higher critical temperature and higher accelerating gradients. While the majority of research efforts are currently focused on the development of elliptical single-cell and multi-cell cavities, the potential of this material is evident to other cavity types, which may have complex geometries. We are working towards the development of Nb₃Sn-coated Half-wave resonator and twin …

Relationship Between Thermal Conductivity And Free Electrons In Metal, Yansong Liu

Senior Theses

An experiment was designed and conducted to explore the relationship between thermal conductivity with free electrons in metal. In the experiment, copper, iron, aluminum, and titanium rods with close diameters were used to carry out the experiment. Each rod was heated up by a heat unit at one end while cooled on the other end with a heat sink to maintain a steady state. DC current was applied to rods in the direction along, as well as against, the heat flow. Thermal conductivities were measured in these two situations for each rod. Results showed electrons do dominate thermal flow inside …

Majorana Quasiparticles In Topological Material Interfaces, David Alspaugh

LSU Doctoral Dissertations

In this dissertation we analyze how Majorana quasiparticles found on material interfaces of both topological insulators (TIs) and topological superconductors (TSCs) are affected by imperfections within their local environment. While these quasiparticles are predicted to be critical for the construction of quantum computers, they are typically modeled only under pristine conditions. Thus, although quantum computers may require the spatial manipulation of Majorana quasiparticles, these topological material interfaces are commonly studied in static contexts and their response to manipulation remains an open question. We first demonstrate that interface potentials on the topological insulator Bi₂Se₃ can enable the emergence …

First I describe the effect on this excitation of negative ion resonances and previous experiments to measure the excitation function, as well as suggestions for future applications of such studies. Then the experimental apparatus is described in three parts. The vacuum system uses a turbomolecular pump to decrease the pressure of the chamber to as low as 4*10^-9 Torr. The electron beam system incorporates a trochoidal electron monochromator to send a highly monochromatic beam …

Identifying, Analyzing, And Using Discriminatory Variables For Classification Of Neutrino Signal And Background Noise In Multivariate Analysis In The Askaryan Radio Array Experiment, Jesse Osborn

Honors Program: Senior Projects (Public)

The Askaryan Radio Array Experiment, located near the South Pole, works to pinpoint specific instances of neutrinos from outside the solar system interacting with nucleons inside the Antarctic ice, emitting radio waves. I have taken data from the ARA stations which is presumed to be background noise and compared it to simulated data meant to look like a neutrino signal. I developed a suite of variables for discrimination between the two data sets, using a computer algorithm to generate a single output variable which can be used to distinguish noise events from signal events. I maximized this discrimination process for …

The Physics Of Fire By Friction, Bradley D. Duncan

Electrical and Computer Engineering Faculty Publications

In what follows I will attempt to produce a rigorous, macroscopic, time averaged model of the process of creating fire by friction – up to the point of initial ember formation. I will employ reasonable, practical approximations with the goal of developing mathematical results that are experimentally verifiable. Although force, velocity, pressure and the like are actually vector quantities, due to the symmetry of the problem I will perform a scalar analysis only. Also, to simplify the analysis I will assume that the assortment of variables we will encounter are independent. Mostly this assumption is valid, though on occasion I …

Electron Beam Dispersion Compensator Using A Wien Filter, Jackson Lederer

Honors Program: Senior Projects (Public)

When an electron beam travels through space, it spreads out over time which impedes the ability to work with short electron pulses in the lab. A Wien filter is a device consisting of perpendicular electric and magnetic fields which filters charged particles based on their velocities. For a specific velocity, the two forces from the two fields in the filter cancel each other out letting charges with that velocity travel straight through the filter. Charges moving at other speeds are deflected as they have a net force applied to them from the filter. If a particle is deflected from the …

Physics Engine On The Gpu With Opengl Compute Shaders, Quan Huy Minh Bui

Master's Theses

Any kind of graphics simulation can be thought of like a fancy flipbook. This notion is, of course, nothing new. For instance, in a game, the central computing unit (CPU) needs to process frame by frame, figuring out what is happening, and then finally issues draw calls to the graphics processing unit (GPU) to render the frame and display it onto the monitor. Traditionally, the CPU has to process a lot of things: from the creation of the window environment for the processed frames to be displayed, handling game logic, processing artificial intelligence (AI) for non-player characters (NPC), to the …

Numerical Solution To A One-Dimensional Nonlinear Problem Of Heat Wave Propagation In A Rigid Thermal Conducting Slab, N H Sweilam, A F Ghaleb, M S Abou-Dina, M M Abou Hasan

Faculty Journal Articles

This work aims at presenting a new numerical solution to a nonlinear, one-dimensional problem of heat wave propagation in a thick slab of a rigid thermal conductor. The model predicts dependence of second sound velocity on temperature and heat flux. For this, an unconditionally stable numerical scheme is constructed using a kind of weighted average nonstandard finite difference discretization. Stability analysis of this scheme is studied by von Neumann technique, and its accuracy is proved. Numerical simulations are given for all quantities of physical interest to confirm the reliability of the proposed method. The model and the numerical results shed …
