Storytelling and Racial Identity: How First-Generation Students of Color Navigate Their Identities at Predominately White Institutions
Get PDFUtilizing the Narrative Paradigm (Fisher, 1984) and thematic analysis (Braun & Clarke, 2006) the present study seeks to explore and further understand the ways in which first-generation students of color navigate, and thus make meaning, of their race and class identities at a Predominantly White Institution (PWI). Through qualitative interviews with 14 first-generation students of color (henceforth, FGSOC), themes that emerged included: (1) being used to “it”, (2) financial differences cause a clash with belonging, and (3) cultural spaces bring welcoming feelings. Findings were consistent with previous research regarding barriers faced by first-generation students of color. The current study adds to the growing body of research on intersectionality within the Communication discipline. Theoretical and practical implications are offered. Study limitations and directions for further research are discussed
Construction of High-Bay Lab Reaction Frame Foundations
Get PDFThis paper details the construction process of two concrete modular foundations designed to meet specific design standards for various testing methods. The project, positioned within the California Polytechnic State University, San Luis Obispo (Cal Poly) High Bay Lab, will provide the Architectural Engineering (ARCE) and Construction Management (CM) departments with valuable insight into industry structural elements. The project required extensive forethought and thoroughness due to the complex designs, including 200 all-thread coupler attachments and a cumbersome rebar cage. This paper outlines the primary phases of construction, including material procurement and quality control, and discusses how the final product was obtained. Furthermore, the paper delves into the mistakes made during the process, with the intention of facilitating potential similar projects leading to more efficient means of success. The project serves as a remarkable demonstration of quality control and strategy when managing a construction project. By outlining the construction process and mistakes made, this paper provides valuable insights for future projects in the field and study. The construction of these two concrete modular foundations will aid students in the ARCE and CM departments for years to come, providing them with a better understanding of specific industry structural elements
TDCOSMO - XII. Improved Hubble Constant Measurement from Lensing Time Delays using Spatially Resolved Stellar Kinematics of the Lens Galaxy
Get PDFStrong-lensing time delays enable the measurement of the Hubble constant (H0) independently of other traditional methods. The main limitation to the precision of time-delay cosmography is mass-sheet degeneracy (MSD). Some of the previous TDCOSMO analyses broke the MSD by making standard assumptions about the mass density profile of the lens galaxy, reaching 2% precision from seven lenses. However, this approach could potentially bias the H0 measurement or underestimate the errors. For this work, we broke the MSD for the first time using spatially resolved kinematics of the lens galaxy in RXJ1131−1231 obtained from the Keck Cosmic Web Imager spectroscopy, in combination with previously published time delay and lens models derived from Hubble Space Telescope imaging. This approach allowed us to robustly estimate H0, effectively implementing a maximally flexible mass model. Following a blind analysis, we estimated the angular diameter distance to the lens galaxy Dd = 865−81+85 Mpc and the time-delay distance DΔt = 2180−271+472 Mpc, giving H0 = 77.1−7.1+7.3 km s−1 Mpc−1 – for a flat Λ cold dark matter cosmology. The error budget accounts for all uncertainties, including the MSD inherent to the lens mass profile and line-of-sight effects, and those related to the mass–anisotropy degeneracy and projection effects. Our new measurement is in excellent agreement with those obtained in the past using standard simply parametrized mass profiles for this single system (H0 = 78.3−3.3+3.4 km s−1 Mpc−1) and for seven lenses (H0 = 74.2−1.6+1.6 km s−1 Mpc−1), or for seven lenses using single-aperture kinematics and the same maximally flexible models used by us (H0 = 73.3−5.8+5.8 km s−1 Mpc−1). This agreement corroborates the methodology of time-delay cosmography
Custom LED Dashboard Integration for the Cal Poly Racing Team
Get PDFThe Custom LED Dashboard Integration was made for the Cal Poly Racing Team, specifically the BAJA division. The dashboard was made as a way to combat the current limitations endured from the past methods used to display critical information of the vehicle to the car. The display was made to combat issues of limited quantity of data being able to be displayed to the driver and its small readability was an issue, the display helped combat that by providing a greater quantity of data being able to be sent and displayed on the display and the information being displayed having a greater clarity for readability in varying environments of the off-roading vehicle
Regenerative Power System ITech ITM-3633
Get PDFIn EE295 classes, students have been using variable resistors and a 125V DC source from the wall. Both of them have weaknesses and therefore, the regenerative power system Itech IT-M3633 is used in this project. Moreover, two of the experiments, 7 and 8, have some problems with the EE295 lab manual. There is accuracy in experiment 7 and experiment 8 has been stopped for a while now by a few professors if not all. These experiments were conducted again with ITech IT-M3633 for better accuracy
Implementation of log4net and Parametric Modeling within the Horizon Simulation Framework
Get PDFCreating system models and simulations allow for rapid, iterative analysis of spacecraft mission performance. This design methodology provides opportunities for improvement before allocating resources towards further physical spacecraft development. Horizon Simulation Framework (HSF) is a system evaluation tool that can be used for the assessment of spacecraft mission performance, subject to mission targets, constraints, and spacecraft design. Specific subsystems are defined for a unique mission case and are evaluated through a Day-in-the-Life (DITL) scenario simulation. Valuable information can be derived from failed attempted mission-related events, highlighting shortcomings in subsystem capabilities. Further information can be unveiled by assessing possible system sensitivity to changes in subsystem parameters. Utilizing HSF as a mission simulation and evaluation tool, this thesis will provide failure analyses of simulated missions that would otherwise be lost using HSF’s original output data, along with the ability to create parametric, multithreaded studies about each system. This thesis will configure HSF’s simulation with differing subsystem attribute values simultaneously to provide an array of solutions for the user to compare and utilize for further optimization of the system for the defined mission
