Designing Acoustics For Linguistically Diverse Classrooms: Effects Of Background Noise, Reverberation And Talker Foreign Accent On Speech Comprehension By Native And Non-Native English-Speaking Listeners, Z. Ellen Peng

Durham School of Architectural Engineering and Construction: Dissertations, Theses, and Student Research

The current classroom acoustics standard (ANSI S12.60-2010) recommends core learning spaces not to exceed background noise level (BNL) of 35 dBA and reverberation time (RT) of 0.6 second, based on speech intelligibility performance mainly by the native English-speaking population. Existing literature has not correlated these recommended values well with student learning outcomes. With a growing population of non-native English speakers in American classrooms, the special needs for perceiving degraded speech among non-native listeners, either due to realistic room acoustics or talker foreign accent, have not been addressed in the current standard. This research seeks to investigate the effects of BNL …

Laminar And Turbulent Regime Changes In Drinking Water Contact Tanks, Taylor C. Barnett, Subhas K. Venayagamoorthy

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Transitions in flow regimes that can occur in drinking water contact tanks may significantly affect the disinfection efficiency of the system. To demonstrate these effects, the authors investigated the internal velocity fields and flow regime of a drinking water contact tank located in Jamestown, Colo. The baffling factor (BF) of the system fluctuated annually between 0.5 and 0.6 because of a shift in flow regime caused by changes in the flow rate of the system. The authors studied the effects of the regime change from laminar to turbulent flow (or vice versa) using computational fluid dynamics (CFD) models and physical …

Methane Production By A Packed-Bed Anaerobic Digester Fed Dairy Barn Flush Water, Sean Richard Thomson

Master's Theses

Packed-bed digesters are an alternative to covered lagoon digesters for methane production and anaerobic treatment of dilute wastewaters such as dairy barn flush water. The physical media of packed-beds retain biofilms, often allowing increased treatment rates. Previous studies have evaluated several types of media for digestion of dilute wastewaters, but cost and media fouling have setback commercial development. A major operational cost has been effluent recirculation pumping.

In the present effort, a novel approach to anaerobic digestion of flush dairy water was developed at pilot-scale: broken walnut shells were used as a low-cost packed-bed medium and effluent recirculation was replaced …

Neighborhoods, Proximity To Daily Needs, & Walkability In Form-Based Codes, Evan Evangelopoulos

Master's Theses

Form-based codes are evaluated with criteria often requiring additional clarification. To better identify form-based code evaluation criteria, this thesis identifies the major intentions of form-based codes from the literature and focuses on the first intention, quality of life. The form-based code literature relates quality of life to three principles with underlying parameters: neighborhood with a center and edge, proximity to daily needs, and walkability. Neighborhood refers to the identification of walkable districts of about .25 mile radius with a clear center and edge. Proximity to daily needs requires diversity of uses in proximity to residential uses so that residents travel …

The Relationship Between Bicycles And Traffic Safety For All Road Users, Jasmine A. Martin

Master's Theses

Over the past twenty years bicycle use as a mode of transportation has grown considerably in the United States. Other studies have examined the individual bicyclist’s risk in proportion to the growth in cycling across cities, a phenomenon referred to as ‘safety in numbers.’ This study expands from that research and examines the effect of cyclists on road safety for all road users.

The study examines the roles of bicycle modal split, a city wide analysis, and bicycle infrastructure, a site based analysis, in road safety outcomes. For the city based analysis, twenty years of crash data in 12 California …

This study rediscovers Shaoshan’s memorial projects undertaken during this period and explores how they embody the complex interplay between art/architecture and politics and the artistic tensions between rural and urban settings in post-Revolutionary China. The text focuses on four endeavors: the historic preservation of Mao’s Old House; the urban renovation plans advanced during the Great Leap Forward; the Exhibition Pavilion constructed by …

Investigating Transformational Leadership And Return On Equity Outcomes In Small And Medium-Sized Community Banks, Jason C. Dean

All-Inclusive List of Electronic Theses and Dissertations

The focus of this investigation is small financial institutions based in the United States and insured by the Federal Deposit Insurance Corporation (FDIC). Without a viable market for community banks individual and small business investors and borrowers, particularly in rural areas, will have less financing options and may be forced to accept the terms dictated by larger financial institutions (Walser & Anderlik, 2004). Additionally, within the literature there is minimal empirical evidence informing community banks of appropriate initiatives that may be implemented to unleash human expertise through training and development interventions related to successful leadership styles. As competition in the …

Engineer Manual 385 Effectiveness: A Study Of Predictive Analytics, Scott Arias

Low-Impact Infrastructure: Development And Design Potential For Surface Application Alternatives For Subsurface Infrastructure In Yellowstone National Park's Upper Geyser Basin, Michael R. Pace

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

In sensitive and iconic landscapes, such as Yellowstone National Park’s Upper Geyser Basin, construction and expansion of visitor services is hindered, and often blocked, by the potential for environmental damage that could occur during the installation of subsurface utilities. These utilities, crucial to the success of development, require an alternative method of installation when placed in locations requiring special consideration and protection.

Yellowstone, in particular, is faced with the responsibility of protecting limited hydrothermal resources while also providing access to the general public. Sub-surface utilities threaten this responsibility due to the unknown nature of much of the subsurface

Finite Element Modelling And Dilation Of Frp-Confined Concrete Columns, Osama Youssf, Mohamed Elgawady, Julie E. Mills, Xing Ma

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Concrete dilation is one of the main parameters that controls the stress-strain behavior of confined concrete. Several analytical studies have been carried out to predict the stress-strain behavior of concrete encased in fiber-reinforced polymer (FRP), which is crucial for structural design. However, none of these studies have provided a simple formula to determine the dilation parameter that is always required in the finite element (FE) material modelling of concrete. This paper presents a simple empirical model predicting the confined concrete dilation parameter within the theoretical framework of a Karagozian and Case type concrete plasticity model. A set of 105 FRP-confined …
