Fabrication Of Lab-Scale Polymeric And Silicon Dioxide Nanoparticle-Enabled Thin Film Composite Reverse Osmosis Membranes For Potable Reuse Applications, Timothy J. Dinh Aug 2022

Fabrication Of Lab-Scale Polymeric And Silicon Dioxide Nanoparticle-Enabled Thin Film Composite Reverse Osmosis Membranes For Potable Reuse Applications, Timothy J. Dinh

Master's Theses

Reverse osmosis (RO) is widely used for water reclamation and is one of the most feasible technologies for addressing water scarcity around the world. RO membrane fabrication procedures are continually being optimized and modified to enhance the treatment performance and efficacy of the RO process. A review of the existing literature published on membrane fabrication revealed that a detailed and reproducible methodology consistent among prior studies was not available. Therefore, the primary objective of this study was to utilize techniques from prior research to develop a reliable lab-scale membrane fabrication process for studying the potable reuse applications of TFC RO …

Prefabrication And Modular Construction: Cm 214 Residential Construction Learning Module, Matthew V. Keeth Jul 2022

Prefabrication And Modular Construction: Cm 214 Residential Construction Learning Module, Matthew V. Keeth

Construction Management

The residential construction industry in the United States has certainly stuck to the conventional methods of stick-built construction nationwide. What if there was a better way? This project seeks to educate future Construction Management students about a smarter, more efficient, and sustainable method of homebuilding: Modular Construction. Distinguishing the difference between prefabrication and modularization is a necessary standard. Prefabrication is defined as the process of manufacturing the essential structural components of a home at a factory off-site. The large scale structural components of a home are then transported to the jobsite for easy installation. In addition, Modular Construction is defined …

Measuring Accessibility For Pedestrians, Bicyclists, And Transit Riders To Grocery Stores In The Excelsior/Outer Mission Neighborhoods Of San Francisco, Alexandra Lee-Gardner Jun 2022

Measuring Accessibility For Pedestrians, Bicyclists, And Transit Riders To Grocery Stores In The Excelsior/Outer Mission Neighborhoods Of San Francisco, Alexandra Lee-Gardner

Master's Theses

Grocery stores are an important amenity in neighborhoods and access to grocery stores is important for health and well-being. While grocery store accessibility is a popular topic of research, studies measuring access for pedestrians, bicyclists, and transit riders are extremely rare. When a new store opened in the Excelsior/Outer Mission districts of San Francisco on a street lacking basic infrastructure for pedestrians, bicyclists, and transit riders, the importance of this study became apparent. The Excelsior/Outer Mission neighborhood has a shocking number of collisions (over 1,100 between 2015 and 2019), elevated levels of walking, biking, and transit ridership, and minimal safe …

Feasibility Report On Water Recycling And The Housing Crisis, Tally A. Perry Jun 2022

Feasibility Report On Water Recycling And The Housing Crisis, Tally A. Perry

City and Regional Planning

The western United States is experiencing increasing population, a housing shortage, and a drought. These challenges demand creative and unprecedented changes to development. Water recycling is slowly emerging as a viable solution for developers, home owners, and cities as a way to continue much-needed housing development while mitigating unnecessary water depletion. With all change, policy, feasibility, and awareness can be the largest influencers. Drought-ridden western-American states require additional and revised regulatory requirements to promote recycled water in new development. Currently, water reuse is largely used for agricultural and industrial purposes. To motivate and encourage housing development, water recycling needs to …

Dynamic Response Of Elastic Two-Story Steel Moment Frame Scaled Structure Equipped With Viscous Dampers, Garrett L. Barker, Alexander L. Poirier Jun 2022

Dynamic Response Of Elastic Two-Story Steel Moment Frame Scaled Structure Equipped With Viscous Dampers, Garrett L. Barker, Alexander L. Poirier

Architectural Engineering

The authors of this report are Architectural Engineering undergraduate students at California Polytechnic State University, San Luis Obispo. Damping is a complex, experimentally derived value that is affected by many structural properties and has a profound effect on the dynamic response of structures. Deducing the inherent damping of a steel moment frame and affecting the damping ratio with viscous dampers are two topics explored in this paper. Dampers are commonly implemented in resilient structures that perform better in a design basis earthquake, reducing the seismic cost and downtime. Undergraduate coursework does not delve into the factors that affect damping and …

Increasing Strength Of Plywood Shear Walls, Elizabeth Claypool, Michelle Dennin Jun 2022

Increasing Strength Of Plywood Shear Walls, Elizabeth Claypool, Michelle Dennin

Architectural Engineering

In a recent iteration of an upper-division engineering design lab course at Cal Poly SLO, students were challenged to identify and understand the probable failure mechanism of conventionally built plywood shear walls and hypothesize how they could delay or prevent common failure mechanisms to increase the overall lateral load capacity. After observing the results of a test on a conventional, code specified wall, a solution to integrate metal gauge strapping into edge nailing was developed to address the common failure mechanisms of nail head pull through and panel edge tear out. A shear wall with metal strapping installed between the …

The Effect Of Inflation And The Pandemic On A Southern California Solar Company: A Case Study, Adrian Avila Jun 2022

The Effect Of Inflation And The Pandemic On A Southern California Solar Company: A Case Study, Adrian Avila

Construction Management

Supply chain issues are causing panic in certain sectors of the economy particularly the solar sector. Solar energy already has problems that can affect its growth in the long term such as lack of government incentives, high cost, and energy curtailment. These problems are becoming more pronounced as the pandemic is prolonged. California is a state that has been encouraging the use of solar energy and has introduced incentives for its citizens to install solar. Because of this, solar companies in California may be able to more adequately circumvent issues and better excel economically than companies in other states. In …
