Local Diurnal Wind‐Driven Variability And Upwelling In A Small Coastal Embayment, Ryan K. Walter, Emma C. Reid, Kristen A. Davis, Kevin Armenta, Kevin Merhoff, Nicholas J. Nidzieko

Physics

The oceanic response to high‐frequency local diurnal wind forcing is examined in a small coastal embayment located along an understudied stretch of the central California coast. We show that local diurnal wind forcing is the dominant control on nearshore temperature variability and circulation patterns. A complex empirical orthogonal function (CEOF) analysis of velocities in San Luis Obispo Bay reveals that the first‐mode CEOF amplitude time series, which accounts for 47.9% of the variance, is significantly coherent with the local wind signal at the diurnal frequency and aligns with periods of weak and strong wind forcing. The diurnal evolution of the …

Roof Diaphragm Distributed Yielding Concept For Improved Seismic Collapse Performance Of Buildings With Rigid Walls/Flexible Roof Diaphragms, Maria Koliou, Andre Filiatrault, D.J. Kelly, John W. Lawson

Architectural Engineering

Buildings with rigid walls and flexible roof diaphragms (RWFD) are a common type of single-story construction in North America, Europe and New Zealand that incorporate rigid in-plane concrete or masonry walls and flexible in-plane wood or steel roof diaphragms. RWFD buildings have shown poor seismic performance during past earthquake events. In particular, it has been observed that the global seismic response is dominated by the response of the roof diaphragm, which is mainly attributed to large in-plane roof displacements that significantly exceed the displacements of in-plane walls. The present study explores the concept of distributed yielding in the flexible roof …

An Alternative Procedure For The Seismic Design Of Buildings With Rigid Walls / Flexible Diaphragms: Fema P-1026, John W. Lawson, Dominic J. Kelly, Maria Koliou, Andre Filiatrault

Architectural Engineering

Evidence indicates that the dynamic behavior of Rigid Wall - Flexible Diaphragm (RWFD) buildings is dominated by the flexible roof diaphragm’s response instead of the walls’ response, and this is a significant departure from the underlying assumptions of the widely used equivalent lateral static force methods in current building codes. RWFD buildings are common in the Americas and other parts of the world, and incorporate rigid in-plane concrete or masonry walls and flexible in-plane wood or steel roof diaphragms. In an effort to improve the seismic performance of this common building type, the National Institute of Building Sciences (NIBS) directed …

Singer, Wittgenstein, And Morally Motivating Examples, Ramona Ilea

Between the Species

Peter Singer’s Animal Liberation played a pivotal role in the animal rights movement and the foundation of modern animal ethics. Using an analysis inspired by Wittgenstein’s remarks on ethics, I will analyze the way in which Singer’s book is structured in order to understand why it succeeds in providing people with the moral motivation to change the way they live. I will argue that the success of Animal Liberation is in large part due to the detailed, carefully chosen, emotionally rich examples and the unusual way in which these examples are juxtaposed, structured, and presented. Understanding how examples can have …

Effects Of Habitat Restoration On Soil Retention On Santa Rosa Island, Michael Perez, Kathryn Mceachern, Ken Niessen

STAR Program Research Presentations

Ranching began on Santa Rosa Island in the 1840’s, consequently introducing nonnative megafauna that put novel selective grazing pressures on endemic plant species. Their movement patterns also altered substrate integrity as the land became denuded of any stabilizing vegetation. Dense groves of island oak (Q. tomentella) are known to aid in sediment deposition and retention. The groves also function to collect water during periods of intense fog common to the island. This experiment sought to determine whether sediment is being lost or deposited on a ridge in the middle of the island containing a grove of Q. tomentella …

Lecture Videos To Supplement Electromagnetic Classes At Cal Poly San Luis Obispo, Dean Y. Arakaki

Electrical Engineering

Electromagnetics and Transmission Lines is a fundamental, yet difficult subject in the Electrical Engineering (EE) field. To help improve information retention, a series of lecture videos was created to supplement traditional lectures, to facilitate in-class discussions, and to improve students’ proficiency and interest in electromagnetics.

Engineering electromagnetics classes at California Polytechnic State University, San Luis Obispo cover fundamentals to understand and analyze cell phone communications, radar systems (air traffic control, law enforcement), and biomedical imaging (MRI). However, this subject also requires considerable mathematics preparation in vector calculus, differential equations, linear algebra, and background in both physics and EE.

Modeling Of Selective Laser Sintering/ Selective Laser Melting, Xuan Wang, Connor West

Industrial and Manufacturing Engineering

Selective laser sintering and selective laser melting are powder based additive manufacturing (AM) process that can rapidly manufacture parts with comparable mechanical properties to conventional manufacturing methods directly from digital files. However, the processing recipe development and design optimization of AM parts are often based on trial and error which erodes the benefit of AM. Modeling is a powerful tool to enable faster development cycle by significantly reducing the experimental efforts. In this paper we discussed the current status of selective laser sintering/melting modeling, in which the laser and powder interaction was studied to understand and predict the process and …

The Politics Of Homelessness In The United States, Jean Williams

Political Science

As the United States grapples with increasing economic inequality and significant poverty, homelessness represents a thorny political and policy issue. This article explores the debates that contrast two primary responses to homelessness, Housing First and the linear, or treatment first, model. Both are employed to address homelessness, though Housing First has been directed almost exclusively to chronic homeless people who are on the streets for long periods of time and contend with mental illness and substance abuse problems. By reviewing the strengths and weaknesses of each type of policy, this article analyzes the philosophy underlying each approach and its impact …

Comparison Of Ac And Dc Led Light Bulb Efficiency For The Dc House Project, Brandon Stafford

Electrical Engineering

This project investigates the efficiency of using LED light bulbs when operated under two different electrical systems: AC and DC systems. The project is in conjunction with the implementation of the DC House system in urban areas. More specifically, this project looks at whether having a hybrid AC and DC system in a typical urban house will increase the efficiency in operating the LED light bulbs, and thus reducing energy consumption and cost. The efficiency of the LED light bulbs are measured by looking at their lumens per watt output. Several light bulbs at four different wattage levels were tested. …

Araucaria In The Urban Landscape: A Novel Leaning Pattern And Evidence Of Cultivated Hybridization, Jason W. Johns

Master's Theses

Our understanding of the natural world is constantly evolving and strengthening as more observations are made and experiments are performed. For example, we understand that tree stems grow toward the light (positive phototropism; Darwin 1880, Loehle 1986, Christie et al. 2013) and against gravity (negative gravitropism; Knight 1806, Hashiguchi et al. 2013). We also know that plants respond to mechanical stimulus and perturbation (thigmotropism; Braam 2005). Genes and their resulting proteins have been described to uncover some of the mechanisms for these environmental responses, but relatively speaking, we have just scratched the surface (Wyatt et al. 2013). While the discovery …

Evaluation Of Career Readiness At An Industrial Technology Program Using A Fuzzy Approach, Ahmed Deif, Cameron Stark, Kathryn Butler, Eric Olsen

Industrial Technology and Packaging

In this research, a quantitative model to measure the “career readiness” performance level of the current curriculum of the Industrial Technology and Packaging program at California Polytechnic State University is proposed. Career readiness is first defined through performance attributes and these attributes are further classified into specific categories and metrics. Using a fuzzy logic computational approach, “career readiness” measures are developed and a “career readiness” score referred to as (CRS) is calculated. The model is designed to be flexible, dynamic and easy to use. It should enable a systematic measurement of career readiness by producing a final integrated unit-less score. …
