Algorithmically Optimized Hemispherical Dome as a Secondary Optical Element for the Fresnel Lens Solar Concentrator

Description: This article focuses on a way to maximize the concentration acceptance product (CAP), while using the minimum SOE and receiver geometry at a given f-number and incidence angle (also referred to as the tracking error angle). The laws of polychromatic light refraction along with trigonometry and spherical geometry were utilized to optimize the POE grooves, SOE radius, receiver size, and SOE–receiver spacing.

Diverse Learners in the Classroom: Students with Special Needs Enrolled in Science, Technology, Engineering, and Mathematics (STEM) Texas Public Classrooms

Description: The purpose of this study was to determine if students with special needs participating in an inclusive classroom can learn the skills related to a STEM career as compared to the general student population. The study involved seventh grade students from two rural middle schools in north central Texas and was framed through a constructivist lens using a quasi-experimental design with a convenience sample. The Solenoid Invention Kit Assessment and the STEM Semantics Survey used in this study were… more

Charpy Impact Testing of Twinning Induced Plasticity and Transformation Induced Plasticity High Entropy Alloys

Description: High entropy alloys (HEAs) are a new class of solid solution alloys that contain multiple principal elements and possess excellent mechanical properties, from corrosion resistance to fatigue and wear resistance. Even more recently, twinning induced plasticity (TWIP) and transformation induced plasticity (TRIP) non-equiatomic high entropy alloys have been engineered, promising increased strength and ductility as compared to their equiatomic counterparts. However, impact and fracture resistance o… more

Characterization, Analysis, and Optimization of Rotary Displacer Stirling Engines

Description: This work focuses on an innovative Rotary Displacer SE (RDSE) configuration for Stirling engines (SEs). RDSE features rotary displacers instead of reciprocating displacers (found in conventional SE configurations), as well as combined compression and expansion spaces. Guided by the research question "can RDSE as a novel configuration achieve a higher efficiency compared to conventional SE configurations at comparable operating conditions?", the goal of this study is to characterize, analyze, an… more

Investigations of the Fresnel Lens Based Solar Concentrator System through a Unique Statistical-Algorithmic Approach

Description: This work investigates the Fresnel-lens-based solar concentrator-receiver system in a multi-perspective manner to design, test and fabricate this concentrator with high-efficiency photon and heat outputs and a minimized effect of chromatic aberrations. First, a MATLAB®-incorporated algorithm optimizes both the flat-spot and the curved lens designs via a statistical ray-tracing methodology of the incident light, considering all of its incidence parameters. The target is to maximize the solar ray… more

The Missing Piece of the Puzzle: A Study of How First-Generation Latino Male College Students Acquire Cultural Capital

Description: This study aimed to take asset-based approach and identify Latino male students who were persisting in college, and to identify what strategies made them successful. This qualitative study consulted Tinto's revised student departure model, Bourdieu's theory of cultural capital, as well as Yosso's theory of community cultural wealth. A phenomenological design was utilized to identify the shared experience of first-generation Latino male college students who had persisted in college and maintai… more
