Generative Suburban Frameworks: Emerging Architect-Guided Optimization Workflows Within Suburban Mass Production, Chris Reeh May 2019

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

Theses from the M. Arch. Program

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 May 2019

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

Theses from the M. Arch. Program

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 May 2019

Combating Zombie Subdivisions In Teton Valley, Idaho, Taylor Cook

Community and Regional Planning Program: Student Projects and Theses

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 ...


Explorations Of Acoustic Trends In Data Logged In K-12 Classrooms, Kieren Smith Apr 2019

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

Architectural Engineering -- Dissertations 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 ...


Voltage And Deflection Amplification Via Double Resonance Excitation In A Cantilever Microstructure, Mohammad H. Hasan, Fadi Alsaleem, Abdallah Ramini Jan 2019

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

Architectural Engineering -- 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 ...


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. M. Alsaleem, S. Ilyas, M. I. Younis Jan 2019

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. M. Alsaleem, S. Ilyas, M. I. Younis

Architectural Engineering -- 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.

Data Driven Approach To Thermal Comfort Model Design, Mostafa Rafaiejokandan Dec 2018

Data Driven Approach To Thermal Comfort Model Design, Mostafa Rafaiejokandan

Architectural Engineering -- Dissertations and Student Research

Apart from the dominant environmental factors such as relative humidity, radiant, and ambient temperatures, studies have confirmed that thermal comfort significantly depends on internal personal parameters such as metabolic rate, age, and health status. This study reviews the sensitivity of the Predicted Mean Vote (PMV) thermal comfort model relative to its environmental and personal parameters of a group of people in a space. PMV model equations adapted in ASHRAE Standard 55–Thermal Environmental Conditions for Human Occupancy, are used in this investigation to conduct a parametric study by generating and analyzing multi-dimensional comfort zone plots. It has been found that ...


Best Practices For Urban Coliving Communities, Rachel Osborne Dec 2018

Best Practices For Urban Coliving Communities, Rachel Osborne

Interior Design Program: Theses

Coliving, a new typology of housing design, has recently been gaining in popularity. Coliving is a form of rental housing that seeks to create community among its residents by providing features such as extensive shared spaces and community managers paired with typically small, furnished private spaces. Little architectural or interior design research is available to describe this emerging typology, and no best-practices or guiding principles exist to aid designers in ­making informed decisions when designing or evaluating coliving spaces.

This thesis uses a mixed-methods approach to understand the composition of existing coliving facilities as well as the motivations and preferences ...


The Diversity Of Modern Urbanism: An International Comparative Study Of Urban Space, Fanhao Kong Dec 2018

The Diversity Of Modern Urbanism: An International Comparative Study Of Urban Space, Fanhao Kong

Theses from the Architecture Program

While industrialization and globalization are continuing to bridge cultural and geographical gaps on the earth, differences still exist. Today, Developing countries are undergoing massive urban transition; and the transition appears to pursue the path of developed countries. However, the belief that global paths of urbanism will converge into one road is not convincing. Many studies on urbanism have been discussed in the past. However, these studies are mainly focused on urban areas in developed countries, mostly located in North America and Europe. In the last ten years, researchers have done more studies in developing areas, especially in East Asia. Though ...


Social Media Communication By Local Governments And Its Implications For Urban Planning, Leiming Zhao Dec 2018

Social Media Communication By Local Governments And Its Implications For Urban Planning, Leiming Zhao

Community and Regional Planning Program: Student Projects and Theses

Social media has altered traditional communication and enriched traditional social networks. In addition to its use for personal communication and business marketing, social media has also been proved to be a valuable tool for urban planners and managers. However, there are relatively few studies about how social media communication may inform the design of urban master plans. The objectives of the thesis are to understand how the city governments have used social media to engage with the general public on urban planning issues, and assess if social media contents can be used to inform urban planning. The 10 top digital ...


An Evaluation Of Public Open Space In Downtown Lincoln, Nebraska, Karl Dietrich Dec 2018

An Evaluation Of Public Open Space In Downtown Lincoln, Nebraska, Karl Dietrich

Community and Regional Planning Program: Student Projects and Theses

Public open space provides many benefits to a downtown area. Among the benefits are economic growth, social connectivity, health, and helping to create an identity for a city. As many cities continue to sprawl outwards, it is important that their downtown areas create a sense of place so that businesses and people stay and visit. Public open spaces can help provide that much needed sense of place. This study examines whether the “public space index” designed by Vikas Mehta (2014) is effective at evaluating public open spaces. This was done by using four public open spaces (Foundation Garden, Tower Square ...


Evaluation Of Hospital Soundscapes To Improve Patient And Staff Experience, Jay Bliefnick Nov 2018

Evaluation Of Hospital Soundscapes To Improve Patient And Staff Experience, Jay Bliefnick

Architectural Engineering -- Dissertations and Student Research

Hospital soundscapes can be difficult environments to assess acoustically due to the continuous activity within units. Routinely, patients perceive these soundscapes poorly when rating their hospital experience on HCAHPS (Hospital Consumer Assessment of Healthcare Providers and Systems) surveys administered after discharge. In addition, hospital staff can be negatively impacted by the acoustical environments in which they work, affecting both performance and job satisfaction. This doctoral research addressed these issues across three phases by collecting acoustical measurements within three individual hospitals, comparing results with provided patient and staff survey information, and conducting laboratory tests of hospital noise perception. In the first ...

Rural Sense: Value, Heritage, And Sensory Landscapes: Developing A Design-Oriented Approach To Mapping For Healthier Landscapes, Judith Van Der Elst, Heather Richards-Rissetto, Lily Díaz-Kommonen Aug 2018

Rural Sense: Value, Heritage, And Sensory Landscapes: Developing A Design-Oriented Approach To Mapping For Healthier Landscapes, Judith Van Der Elst, Heather Richards-Rissetto, Lily Díaz-Kommonen

Anthropology Faculty Publications

Landscape design needs a novel value system centred on human experience of the landscape rather than simply on economic value. Design-oriented research allows us to shift the focus from mechanistic paradigms towards new sensemaking approaches that value both the sensual and the cognitive in human experience. To move in this direction, we investigate cultural and natural aspects of sensory experience in rural landscapes, arguing that: (1) rural (non-urban) regions offer diverse sensory experiences for optimising human health; and (2) spatial interconnectedness between rural and urban areas means that healthy rural regions are critical for urban development. Our key argument is ...

Participating in the Landscape Architecture Foundation’s 2018 Case Study Investigation has been an incredibly informative experience for our research team at the University of Nebraska-Lincoln. We are eager to shine a spotlight on the landscape performance of two Great Plains projects: P Street Corridor, a revitalized downtown streetscape in Lincoln, Nebraska, and Tom Hanafan River’s Edge Park, a waterfront redevelopment in Council Bluffs, Iowa. Working on the post-occupancy study of both projects has been extremely beneficial in understanding how reclaiming underutilized sites can create high-performing landscapes. Both are public projects in urban settings with primary goals of transforming ...


Analyzing The Impact Of Incentive Programs On Retention Of Family Practice Providers In Rural Nebraska, Andrew J. Pedley Jul 2018

Analyzing The Impact Of Incentive Programs On Retention Of Family Practice Providers In Rural Nebraska, Andrew J. Pedley

Community and Regional Planning Program: Professional Projects

Rural populations in Nebraska are generally older, less affluent and suffer from more chronic diseases than their urban counterparts. To address these disparities, the Nebraska Department of Health and Human Services Office of Rural Health oversees incentive programs that compensate providers for costs associated with education in exchange for time worked in shortage areas. This report examines the impact that these incentive programs have on the retention of family medicine providers in Nebraska using survival analysis methodologies. The findings of this report indicate a positive correlation between participation in incentive programs and workforce retention of family medicine providers.

Force-Driven Weave Patterns For Shell Structures In Architectural Design, Khaled Amir Benaida Jul 2018

Force-Driven Weave Patterns For Shell Structures In Architectural Design, Khaled Amir Benaida

Theses from the Architecture Program

The use of lightweight carbon fiber reinforced polymers (CFRP) in the discipline of architecture opens new possibilities for the construction of architectural components. CFRP has been explored mainly in engineering fields, such as aeronautics, automotive, ballistic and marine engineering. CFRP has also been explored in the discipline of architecture in the construction of shell structures because of its high strength-to-weight ratio and low-cost. There is, however, limited research on how structural analysis can be used to inform weave patterns for shell structures using CFRP.

Further, previous research in the field has not performed physical structural tests to validate which force ...


Seventy-Five North Developments: A Holistic Approach To Improving Northeast Omaha, Fabiola Alikpokou Jun 2018

Seventy-Five North Developments: A Holistic Approach To Improving Northeast Omaha, Fabiola Alikpokou

Community and Regional Planning Program: Student Projects and Theses

The concentration of public housing in high-poverty neighborhoods has many negative impacts; it limits educational opportunities for kids, leads to increased crime, causes poor health outcomes, hinders wealth building, and decreases investments (U.S. Department of Housing and Urban Development, 2013). Northeast Omaha exhibits many of these issues. North Omaha is not only home to many of the city's minority persons, but also home to one of the most impoverished Black communities in the United States (Cordes, Gonzalez, & Grace, 2011). The Omaha-Council Bluffs area was ranked 14 for the highest African-American poverty rate out of 100 most populous metro ...


Recycled Substrates: Plant Biomass And Plant Cover Correlation, Richard K. Sutton May 2018

Recycled Substrates: Plant Biomass And Plant Cover Correlation, Richard K. Sutton

Landscape Architecture Program: Faculty Scholarly and Creative Activity

Green roofs extend roof membrane life and reduce waste to landfills. However, green roof costs must be reduced if their benefits are to accrue more widely. Use of recycled materials may reduce costs and also keep those materials out of landfills. Some work has been done on use of local recycled materials for green roof substrates, but none describe the characteristics, proportions and results of using an entire suite of blended recycled materials in admixtures (i.e., mixtures of very different materials) such as crumb rubber (CR), crushed used brick (CB) and compost (CPT) in concert with greens grade sand ...

A Case Study On The Design Of Safe Spaces In Hospitals Vulnerable To Tornadoes In Central Us, Lucy Owusua Ampaw - Asiedu

Architectural Engineering -- Dissertations and Student Research

In the wake of recent disasters happening around the world such as the earthquake in Italy (January 2017); hurricanes in the United States (U.S.) (September 2016 and 2017); and compounding disasters in Haiti (September 2010 and 2016); to our best knowledge, never has the world seen the need to work on preemptive rather than reactionary measures to address this issue. Tornadoes are natural hazards that commonly occur in mid-western and central states of the U.S. Tornadoes, like all natural hazards, are very destructive and result in massive destruction to building structures, causing billions of dollars in damage and ...


Challenging The Norm Of Minimums: A Case Study Of Ada Design Standards On The University Of Nebraska-Lincoln Campus, Emily Drummy May 2018

Challenging The Norm Of Minimums: A Case Study Of Ada Design Standards On The University Of Nebraska-Lincoln Campus, Emily Drummy

Interior Design Program: Theses

In the United States, over 30 million people have difficulties climbing stairs and require the use of a walker, cane, or wheelchair to move around (United States Census Bureau, 2012). All people interact with the built environment around them, including the some thirty million who deal with physical difficulties. While some can navigate the space around them easily, others have more difficulty due to certain barriers. Often, interior environments are designed with the able bodied in mind, not accommodating properly for the disabled even in the most basic of ways. Despite the introduction of the Americans with Disabilities Act (ADA ...


A Spatiotemporal Analysis To Identify Naturally Occurring Retirement Communities In Nebraska, Sangho Lee May 2018

A Spatiotemporal Analysis To Identify Naturally Occurring Retirement Communities In Nebraska, Sangho Lee

Community and Regional Planning Program: Student Projects and Theses

This study aims to identify the geographic locations of “naturally occurring retirement communities (NORCs)” and whether there were spatiotemporal patterns of naturally occurring retirement communities in Nebraska for the time periods of 2000 to 2010, and to 2015. As the American population continues to age, older people generally prefer to live in their own homes for later years of life, instead of moving into assisted living. These demands have resulted in the increase of elderly populations who are “aging in place”. Nevertheless, there have been few spatiotemporal analyses about the distribution patterns of elderly households in terms of NORCs for ...


Development Of A Model To Predict The Likelihood Of Complaints Due To Assorted Tone-In-Noise Combinations, Joonhee Lee, Lily M. Wang May 2018

Development Of A Model To Predict The Likelihood Of Complaints Due To Assorted Tone-In-Noise Combinations, Joonhee Lee, Lily M. Wang

Architectural Engineering -- Faculty Publications

This paper develops a model to predict if listeners would be likely to complain due to annoyance when exposed to a certain noise signal with a prominent tone, such as those commonly produced by heating, ventilation, and air-conditioning systems. Twenty participants completed digit span tasks while exposed in a controlled lab to noise signals with differing levels of tones, ranging from 125 to 1000 Hz, and overall loudness. After completing the digit span tasks under each noise signal, from which task accuracy and speed of completion were captured, subjects were asked to rate level of annoyance and indicate the likelihood ...


Road Diet Feasibility Analysis For Nebraska, Brandon L. Purintun May 2018

Road Diet Feasibility Analysis For Nebraska, Brandon L. Purintun

Civil Engineering Theses, Dissertations, and Student Research

Many rural towns and cities throughout Nebraska have experienced consistent population decline over the past 50 years, and the highway system once built to accommodate hoped-for growth is not serving the population as well as it could. These towns and cities would benefit from implementing a road diet conversion on their main highways. Within rural communities, road diets are an increasingly popular method of improving safety along major arterials through the reduction of excess capacity in favor of increasing refuge areas for turning vehicles. A typical application might be the restriping of a four-lane undivided highway into a three-lane highway ...


Effects Of Reverberation Conditions And Physical Versus Virtual Source Placement On Localization In Virtual Sound Environments, Anna Catton Apr 2018

Effects Of Reverberation Conditions And Physical Versus Virtual Source Placement On Localization In Virtual Sound Environments, Anna Catton

Architectural Engineering -- Dissertations and Student Research

Sound field synthesis systems vary in number and arrangement of loudspeakers and methods used to generate virtual sound environments to study human hearing perception. While previous work has evaluated the accuracy with which these systems physically reproduce room acoustic conditions, less is known on assessing subjective perception of those conditions, such as how well such systems preserve source localization. This work quantifies the accuracy and precision of perceived localization from a multi-channel sound field synthesis system at Boys Town National Research Hospital, which used 24 physical loudspeakers and vector-based amplitude panning to generate sound fields. Short bursts of broadband speech-shaped ...

Wetland Conservation Effects Result In Enhanced Playa Functionality In The Rainwater Basin, Nebraska, Hong Zhang

Community and Regional Planning Program: Student Projects and Theses

This study assessed the functionality level of wetland hydrology, hydrophyte and soil conditions, and then identified the restorable potential of conserved playas. The distribution of hydrology and hydrophyte were geospatially examined through annual tracking the quantity and quality of wetlands on historical hydric soil footprints under different conservation programs in the Rainwater Basin (RWB) in Nebraska, USA during 2004-2015. The results show that the historical hydric soil footprints with the conservation programs had significantly higher functionality of ponded water and hydrophyte than non-conserved wetlands. The yearly average of ponded water areas within footprints varies at 12.59% for the Waterfowl ...
