Assessment Of Musculoskeletal Disorders (Msds) Risk During The Framing Of A 6' X 8' Wooden Shed Using Traditional Hammers, Maxwell R. Helfman

Construction Management

Wood-framed construction will almost always use nails as a connector whether it be for different pieces of wall sections or connecting wall sections to the structure. Nails also act in Shear Walls in different nailing patterns to prevent the panel from splitting. Houses in modern times are usually nailed with nail guns, either with a cord or cordless, which reduces their exposure to Musculoskeletal disorders (MSDs). However, smaller jobs may opt to use traditional hammers instead of nail guns. This study aims to numerically quantify the forces and flexions one puts on the body when performing nailing tasks using a …

Exploring Mass Timber And Mitek Posi-Strut System In Modern Construction, Matthew N. Maloney

Construction Management

This study evaluates the performance, cost-effectiveness, and constructability of two different truss systems by constructing identically sized mockup models. The comparison focuses on the top chord POSI-Strut Metal Web System and the bottom chord truss system, both utilizing Boise Cascade LVL engineered lumber. Our findings reveal that the top chord POSI structure truss system is more cost-effective and time-efficient compared to the bottom chord truss system. The top chord system's design reduces material costs and speeds up construction time, making it an attractive option for projects with tight budgets and schedules. However, the top chord POSI-Strut Metal Web System has …

Characterization Of High Albedo Ground Surface Treatments For Energy Harvesting By Bifacial Photovoltaic Power Plants, Roma C. Chatripally, Matthew Honda, James Vance

Materials Engineering

Bifacial photovoltaic (bPV) cells have higher solar efficiency than monofacial photovoltaic (mPV) cells due to having two sides of active layers. bPV cells also require less space to produce equivalent electricity, which is useful for solar farms that want to maximize energy output per unit area. Placing a sheet of highly reflective material on the surface beneath bPV cells further increases their efficiency due to increasing the amount of solar radiation that reaches the underside of the bPV cells. This study explores the effects of natural outdoor weathering, solar altitude angle, and accelerated exposure to UV radiation on the albedos …

Sustainable Land Initiative Infographics, Riley M. Cameron, H. Rain Mazumder, Peyton Fraley, Sarah Sykora

Graphic Communication

The Sustainable Land Initiative (SLI) is a collaborative program between farmers, Resource Conservation Districts (RCDs), and universities that is aimed at hastening the California agricultural industry’s adoption of climate-smart agriculture (CSA) practices to mitigate and adapt to the effects of climate change on the environment. One aspect of the program involves removing the various barriers that local farmers face during the CSA practice adoption process, which includes a lack of outreach and education. To help tackle this obstacle, our senior project team has developed infographics on three different CSA practices with two main objectives: educate growers on the benefits of …

Resources To Support Adu Construction, Eleanor Rheingans

Construction Management

This survey examines whether cities with a higher number of online resources will result in a higher proportion of ADU permits and a lower wait time for approval. Some cities have offered online resources directly related to the ADU permitting and construction process. The seven online resources were selected based on interviews with developers. Data used is from 2018 to 2023. Other factors seem to affect the number of permits issued more than resources the cities post for public access. While developers do want the resources cities are currently offering, there are some gaps, particularly records of past permit costs …

Performance Interference Detection For Cloud-Native Applications Using Unsupervised Machine Learning Models, Eli Bakshi

Master's Theses

Contemporary cloud-native applications frequently adopt the microservice architecture, where applications are deployed within multiple containers that run on cloud virtual machines (VMs). These applications are typically hosted on public cloud platforms, where VMs from multiple cloud subscribers compete for the same physical resources on a cloud server. When a cloud subscriber application running on a VM competes for shared physical resources from other applications running on the same VM or from other VMs co-located on the same cloud server, performance interference may occur when the performance of an application degrades due to shared resource contention. Detecting such interference is crucial …
