A bridge is inserted around the protruding end of the shear connector and a fastener is installed onto the protruding end of the shear connector to engage the bridge and urge the bridge in abutting relation with a lip of the sleeve . The pocket …

The Relationship Between Separated Bicycle Lanes And Bicycle Crashes In Denver, Colorado., Wonsun Chang

Community and Regional Planning Program: Theses and Student Projects

Cyclists feel more comfortable when they ride in a bike facility separated from traffic. Therefore, cyclists tend to prefer separated bicycle lanes over other lanes. It follows that cities are increasing the installation of separated bicycle lanes for bicycle utilization and bicycle safety. However, previous research has proven that separated bicycle lanes cause more crashes. Through empirical study, this paper examined the impact of both separated bicycle facilities and shared roads on bicycle crashes and which is safer or dangerous among methods of the separation. This study deals with bicycle accidents in Denver from 2013 to 2019. This research creates …

Long-Term Changes Of Open-Surface Water Bodies In The Yangtze River Basin Based On The Google Earth Engine Cloud Platform, Yue Deng, Wei-Guo Jiang, Zhenghong Tang, Ziyan Ling, Zhifeng Wu

Community and Regional Planning Program: Faculty Scholarly and Creative Activity

The spatiotemporal changes of open-surface water bodies in the Yangtze River Basin (YRB) have profound influences on sustainable economic development, and are also closely relevant to water scarcity in China. However, long-term changes of open-surface water bodies in the YRB have remained poorly characterized. Taking advantage of the Google Earth Engine (GEE) cloud platform, this study processed 75,593 scenes of Landsat images to investigate the long-term changes of open-surface water bodies in the YRB from 1984 to 2018. In this study, we adopted the percentile-based image composite method to collect training samples and proposed a multiple index water detection rule …

Digitally-Mediated Practices Of Geospatial Archaeological Data: Transformation, Integration, & Interpretation, Heather Richards-Rissetto, Kristin Landau

Department of Anthropology: Faculty Publications

Digitally-mediated practices of archaeological data require reflexive thinking about where archaeology stands as a discipline in regard to the ‘digital,’ and where we want to go. To move toward this goal, we advocate a historical approach that emphasizes contextual source-side criticism and data intimacy—scrutinizing maps and 3D data as we do artifacts by analyzing position, form, material and context of analog and digital sources. Applying this approach, we reflect on what we have learned from processes of digitally-mediated data. We ask: What can we learn as we convert analog data to digital data? And, how does digital data transformation impact …

Two objectives are used to assess the viability of tiny housing in this Midwestern state. The first analyzes the economics (demand, supply, and cost) of tiny housing in metropolitan areas of Nebraska. The second identifies barriers to occupancy of tiny houses in the state. The results of this research are significant because tiny housing presents a means to address the state’s need for more affordable housing options available to Nebraska residents. At the time of this study, 11.4% of Nebraska’s …

Designing Single-Family Residences: A Study Of The Positive Impact Of Interior Design In Creating New Home Value, Shawn M. Falcone

Interior Design Program: Theses and Other Student Work

This study seeks to demonstrate that interior designers should be included as primary stakeholders in the home construction market. The market demand for new single-family homes in America is a relative constant. The primary stake and role that land developers, architects, draftsman, home builders, bankers, appraisers, real estate agents, and buyers have in the home construction market is clear. What is less clear is the role in value an interior designer has in the home construction market. This thesis examines the impact designers have on home value when their expertise is utilized in space planning (i.e.: layout, function, room utilization, …

Workforce Development Through Online Experiential Learning For Stem Education, Arefeh Mohammadi, Kevin Grosskopf, John Killingsworth

Durham School of Architectural Engineering and Construction: Faculty Publications

The U.S. workforce is increasingly comprised of older adults, women, and minorities who lack basic skills and are unable to acquire these skills through traditional educational and training programs. New approaches are needed to provide effective training to the adult learner and flexible support for nontraditional students who must balance work-life demands with limited educational opportunities. Contextualized teaching and learning (CTL) is a form of experiential learning that blends both basic skills and occupational training together in environments that allow students to relate subject matter to real-world situations. Virtual CTL environments can be created to better engage students, provide immediate …

Machine Learning In Architecture: Connectionist Approach To Architectural Design, Andrew Chase

Masters in Architecture Program: Theses

Previous applications to design processes intend to enhance a building’s schematic design using quantitative data. Therefore, most applications to the early design phases are passed by as simple overarching ideas informed by the designer and users’ knowledge. Although this is a preferred method of choice making, the knowledge used to inform conceptual and schematic design process can be limited. With the increase of computation in all major industries, a new increase in data to describe forms of infrastructure is required. These forms being objects to analyze their performance and potential, and active forms that can describe the disposition of urban …

Generative Suburban Frameworks: Emerging Architect-Guided Optimization Workflows Within Suburban Mass Production, Chris Reeh

Masters in Architecture Program: Theses

The mass production of single-family housing has led to a number of overlooked design problems, including enormous physical footprints, subpar construction, and hastily installed infrastructure (Florida 2017). The continued growth of this development strategy has decreased the disparity of the building type, which also undergoes far less design consideration than other building typologies. Solutions to these issues have been oriented around concepts of modular construction and prefabricated elements. These ideas have typically remained in conceptual design stages, and when actualized they tend to lack the simplicity, speed, or cost of current residential construction practices. Additionally, several of these approaches could …

Blend Space: Architectural Storytelling In The Age Of Mixed Reality, Grant Moehlenhoff

Masters in Architecture Program: Theses

Storytelling and narratives have long been traditions for communication in human culture. Hieroglyphics, cave paintings, and stone tablets became the mediums in which this common method of communication began. The reasons why people tell stories are numerous, the most common ones being to entertain, to keep cultural heritage, to transfer knowledge, or provide warnings to others of danger. In addition, cultures often use architecture as a place to embed these narratives.

As technology has rapidly developed, so have the modes for telling stories. Today, stories are moving beyond the physical, and into both virtual and mixed realities. Virtual and augmented …

Combating Zombie Subdivisions In Teton Valley, Idaho, Taylor Cook

Community and Regional Planning Program: Theses and Student Projects

This research examined the history, background, and viable solutions to deal with zombie subdivisions in the Teton Valley area (Teton County, Idaho). Overdevelopment, lack of responsible zoning code enforcement and the 2008 economic recession are just some of the key factors that contributed to the ongoing dilemma of zombie subdivisions in the Teton Valley. The current and past long-range plan for Teton County, Idaho was reviewed and analyzed to understand the workings and planning mechanisms that were and are currently set in place. Zoning code, Idaho state statutes and development agreements between Teton County officials and developers, were closely reviewed …

Agnosia, Hilary Wiese

Masters in Architecture Program: Theses

This thesis “Agnosia, a parallel history of the figures of the infra-ordinary” explores the contemporary possibilities for architecture to be critical as well as projective, to formulate a position while learning from the past, to provoke the present with the hope to liberate the future.

The critical positioning that the work engages with is feminism in architecture, women’s under-recognized voices in the making of modern architectural history and how their contributions should be studied to cultivate new contemporary perspectives in architecture practices and architectural pedagogy.

Formulated through text, narratives, poems, research but also total installations, object making, movie making and …

Architecture For The Atypical: Architectural Diffusion, Diane Nguyen

Masters in Architecture Program: Theses

The study of phenomenology within architecture is rooted in the emphasis of the experience of the human body. The ability to understand how a human inhabits a space is crucial; through the study of the human experience, we are able to study phenomenology within architecture. But what happens when the human body doesn’t react the way that we, as architects, desire? Since the reliance on vision is the most prominent sense for a phenomenological experience of a space, taking away that sense seems to lessen the impact. As a result, this privileging of vision leads to missed opportunities within design. …

Type Theory, Paris Mood

Masters in Architecture Program: Theses

The concept of type and typology are at the heart of Architecture. Type is the simple act of drawing similarity and difference between a group of artifacts. Typology, on the other hand, is a bit more complicated. When one engages with typology, they are taking the information they gather from observing the artifacts and transposing it into a new context. Most designers and architects refer to this act as type/typology. The distinction between the two terms is necessary for my work. My work looks at the relationship between these two events. As a collective they are Type Theory.

My current interest lies in micro-architecture because its a scale I feel I can be in complete control of the outcome. Also a smaller …

Automated Generation Of Daily Evacuation Paths In 4d Bim, Kyungki Kim, Yong-Cheol Lee

Durham School of Architectural Engineering and Construction: Faculty Publications

Spatial movements of workers and equipment should be carefully planned according to project plans. In particular, it is crucial for workers’ safety to prepare emergency evacuation paths according to changing construction site configurations and construction progress. However, creating evacuation paths for all crews for each day can be an extremely labor-intensive task if it is done manually. Consequently, in most construction projects, evacuation plans are not provided to managers and crews throughout the entire construction. Even state-of-the-art technologies do not suggest ways to generate evacuation paths according to changing progresses presented in 4-Dimensional Building Information Model (4D BIM). This research …

The Antithesis: Challenging The Current Execution Of University Thesis Via The Exquisite Capriccio And Grand Tour, Joshua D. Puppe

Masters in Architecture Program: Theses

Dimensions Of Surveillance, Prisoners Of The Planetary Panopticon, Mallory R. Lane

Masters in Architecture Program: Theses

This project explores the Prisoners of the Planetary Panopticon. Surveillance no longer exists solely within an architectural scale, but has expanded to the urban, territorial, and planetary scale.

At the beginning of this thesis I began researching the contemporary issues of prisons and found that issues now extend far beyond the walls of the grounds. When comparing the architecture of Jeremy Bentham's Panopticon to today's society, what separates our exposed, surveilled bodies from those within the Panopticon Prison of the 1800's? This subject is relevant at a time when surveillance has taken over the city and created another spatial world …

Architecture In Neoliberalism, Ben J. Kunz

Masters in Architecture Program: Theses

Neoliberalism, as a form of capitalism that redistributes wealth to existing accumulations of money, has reorganized our society around market relations resulting in extreme inequality. Architecture has been both captive and complicit in this process because it relies on the largess of its clients who benefit most from the process of neoliberalization. We must dissolve the dogma of architectural practice, and become free entrepreneurial operators in a neoliberal society with architecture as a core skill set, able to operate on risk and its dimensions of time, space, and money without the servitude to our risk ordered professional relationships in order …

The Experience Condition: Experiencing Alternate Futures, Holly R. Craig

Masters in Architecture Program: Theses

A B S T R A C T I n t r o In The Human Condition, Hannah Arendt states that the human capacity for new beginnings is marked by the launch of the first satellite into space in 1957. Arendt recognizes this as an ‘event, second in importance to no other, not even to the splitting of the atom’. The minatory threat of technological enterprises, the advent of automation, virtual and cosmic colonization, climatic changes, and todestrieb or ‘death drive,’ belong to a scope of events that impel new forms of experiences. (1)(2)(3) Narrative Architecture will be used …

Community and Regional Planning Program: Faculty Scholarly and Creative Activity

Extension professionals are increasingly using geographic information system (GIS) technology to develop and inform programs and services. In this article, we use a mapping exercise to demonstrate how the unit of data can be applied and inadvertently misrepresented in GIS mapping. We contrast the use of counts, percentages, and location quotients with the same data and the resulting divergence in maps. The discussion addresses ideal circumstances for using each unit of data. Overall, the article illustrates the need for Extension professionals to be cognizant of the benefits and limitations of various units of data to avoid miscommunication when using GIS …

Detection Of Linkage Between Solar And Lunar Cycles And Runoff Of The World's Large Rivers, Zhijun Dai, Jinzhou Du, Zhenghong Tang, Suying Ou, Samuel Brody, Xuefei Mei, Jietai Jing, Shoubing Yu

Community and Regional Planning Program: Faculty Scholarly and Creative Activity

It is an ongoing concern that global hydrological cycle can be likely intensified under context of climate change and anthropogenic actions. Here, our results show that the solar and lunar periodic motions (SLPMs) have substantial impact on the runoff of the world's large rivers. We estimate that SLPMs can produce a change of the world's large rivers runoff by as much as 6.7%. Although climate models suggest that the increased frequency of extreme events is attributed to anthropogenic activities, it is out of our expectation that as much as 73% and 85% of the extreme flood and drought events (based …

The article emphasizes the need for Extension professionals to consider the effects of data grouping to avoid miscommunication when using GIS mapping.

The Augmented Drift, Kylie Miller

Masters in Architecture Program: Theses

This thesis aims to define and understand the role in which technology plays on human perception and its relationship to architecture. This is to critically analyze the changes and manipulations of the body within regards to new technological systems. These are analyzed under the frameworks of body perceptual systems and their levels of engagement. This then allows for experimentation of sensory manipulation to test the body’s responsive and reactionary techniques.

The design of this thesis explores the opportunities in crossing, amplifying, and re-contextualizing the body and senses within the regards of the technological impacts. This is implored through physical prosthetic …

Explorations Of Acoustic Trends In Data Logged In K-12 Classrooms, Kieren Smith

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

The classroom environment influences the ability of children to learn. To ascertain the effect of indoor environment parameters on student achievement, a large-scale project was launched, collecting time-logged data from 220 k-12 classrooms in the eastern Nebraska region for six days each. Data were collected from a variety of disciplines, including acoustics, lighting, indoor air quality, and thermal comfort. This thesis focuses on the acoustic parameters, looking first at how overall classroom values--including average sound levels and room reverberation time--influence student achievement. Using structural equation modeling, the average sound level during times with speech present was discovered to have a …

Post-Earthquake Assessment And Numerical Modeling Of Freestanding Heritage Structures, M. Khalid Saifullah, Christine E. Wittich

Department of Civil and Environmental Engineering: Faculty Publications

Historic and heritage structures are particularly vulnerable to earthquakes, where damage or collapse can not only lead to loss of a structure but also the loss of irreplaceable heritage. Many heritage structures can be classified as freestanding (detached) structures, including unreinforced masonry walls, classical multi-drum columns, and statue-pedestal systems. However, the seismic response of freestanding structures (sliding, rocking, rock-slide, overturning) is poorly predicted by existing methods due to geometric non-linearities as well as sensitivity to interface conditions and modeling parameters. Previous studies have focused on analytical modeling of simplified systems and/or experimentation under controlled laboratory conditions. In contrast, this paper …

Efficient Excitation Of Micro/Nano Resonators And Their Higher Order Modes, N. Jaber, M. A. A. Hafiz, S. N. R. Kazmi, M. H. Hasan, F. Alsaleem, S. Ilyas, M. I. Younis

Durham School of Architectural Engineering and Construction: Faculty Publications

We demonstrate a simple and flexible technique to efficiently activate micro/nano-electromechanical systems (MEMS/NEMS) resonators at their fundamental and higher order vibration modes. The method is based on the utilization of the amplified voltage across an inductor, L, of an LC tank resonant circuit to actuate the MEMS/NEMS resonator. By matching the electrical and mechanical resonances, significant amplitude amplification is reported across the resonators terminals. We show experimentally amplitude amplification up to twelve times, which is demonstrated to efficiently excite several vibration modes of a microplate MEMS resonator and the fundamental mode of a NEMS resonator.

Voltage And Deflection Amplification Via Double Resonance Excitation In A Cantilever Microstructure, Mohammad H. Hasan, Fadi Alsaleem, Abdallah Ramini

Durham School of Architectural Engineering and Construction: Faculty Publications

Cantilever electrostatically-actuated resonators show great promise in sensing and actuating applications. However, the electrostatic actuation suffers from high-voltage actuation requirements and high noise low-amplitude signal-outputs which limit its applications. Here, we introduce a mixed-frequency signal for a cantilever-based resonator that triggers its mechanical and electrical resonances simultaneously, to overcome these limitations. A single linear RLC circuit cannot completely capture the response of the resonator under double resonance excitation. Therefore, we develop a coupled mechanical and electrical mathematical linearized model at different operation frequencies and validate this model experimentally. The double-resonance excitation results in a 21 times amplification of the voltage …

Experiencing Extreme Height For The First Time: The Influence Of Height, Self-Judgment Of Fear And A Moving Structural Beam On The Heart Rate And Postural Sway During The Quiet Stance, Mahmoud Habibnezhad, Jay Puckett, M. S. Fardhosseini, Houtan Jebelli, Terry Stentz, L. A. Pratama

Durham School of Architectural Engineering and Construction: Faculty Publications

Falling from elevated surfaces is the main cause of death and injury at construction sites. Based on the Bureau of Labor Statistics (BLS) reports, an average of nearly three workers per day suffer fatal injuries from falling. Studies show that postural instability is the foremost cause of this disproportional falling rate. To study what affects the postural stability of construction workers, we conducted a series of experiments in the virtual reality (VR). Twelve healthy adults—all students at the University of Nebraska-Lincoln—were recruited for this study. During each trial, participants’ heart rates and postural sways were measured as the dependent factors. …
