The Impact Of Trees On Passive Survivability During Extreme Heat Events In Warm And Humid Regions, Ulrike Passe, Janette R. Thompson, Baskar Ganapathysubramanian, Boshun Gao, Breanna L. Marmur

Natural Resource Ecology and Management Conference Papers, Posters and Presentations

Communities are increasingly affected by excessive heat. The likelihood of extreme heat events is predicted to increase in the Midwest region of the United States. By mid-century (2036–2065), one year out of 10 is projected to have a 5-day period that is 13°F warmer than a comparable earlier period (1976–2005). The frequency of high humidity/dew point days (“extra moist tropical air mass days,” MT++ synoptic climate classification system) has also increased significantly during a similar period (1975–2010) and between 2010 and 2014 included 8 of 26 heat events. This impact is exacerbated by the fact ...

PLACEMAKING IN METRO EAST SPRINGFIELD - Creating a Landscape Framework

Placemaking in Metro East Springfield – Creating a Landscape Framework provides strategies to use the landscape as a framework for rebuilding community in a downtown urban area that has “good bones” but has been neglected and overlooked for decades. A catalyst for the development of project area is the recent acquisition of the historical 1916 Willys Overland building through a developer. The Graduate Urban Design Studio 2018 developed five proposals for urban revitalization in the area that are centered on the landscape. The programming of the proposals was developed in collaboration with ...


Not Parking Lots But Parks: A Joint Association Of Parks And Transit Stations With Travel Behavior, Keunhyun Park, Dong-Ah Choi, Guang Tian, Reid Ewing Feb 2019

Not Parking Lots But Parks: A Joint Association Of Parks And Transit Stations With Travel Behavior, Keunhyun Park, Dong-Ah Choi, Guang Tian, Reid Ewing

Landscape Architecture and Environmental Planning Faculty Publications

Urban design literature says that public open space in a station area could promote walking and other types of physical activity, enhance place attractiveness, and increase property values. In the context of station areas, however, there is a lack of empirical studies on the relationship between the presence of parks and sustainable travel behavior, which is one of the primary goals of transit-oriented developments (TODs). This study examined the impact of park provision on transit users’ mode choice in three U.S. regions: Atlanta (GA), Boston (MA), and Portland (OR). This study utilized multilevel multinomial logistic regression to account for ...


Design For Living Complexities, Peter J. Taylor Jan 2019

Design For Living Complexities, Peter J. Taylor

Working Papers in Critical, Creative and Reflective Practice

Lectures from a 12-session course that addresses the intersection of design with critical thinking. Design in this course means intentionality in construction, which involves a range of materials, a sequence of steps, and principles that inform the choice of materials and the steps. Design also always involves putting people, as well as materials, into place. This happens by working with the known properties of people, as well as the known properties of material, and trying out new arrangements to work around their constraints (at least temporarily). Critical thinking, as I define it, involves understanding ideas and practices better when we ...


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 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. 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.


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 ...

The Kalinago are the Indigenous people of Dominica.Hurricane Maria hit the people particularly hard, losing up to 90% of their homes and community fabric. The people also suffered before the storms. Discrimination, little government aid, no electrical grid, isolation in their mountainous territory, limited social services, and economic mobility. The people have grown up relaying on themselves and their neighbors. With most of the housing stock gone, new building strategies need to be implemented. The goal is to make the territory self-sufficient, and a working expo society about sustainable living and resilience. The territory will undergo a master plan ...


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 ...

Energy Use And Weatherization Practices: Applications For Agent-Based Modeling To Support Vulnerable Populations, Jacklin Stonewall, Wanyu Huang, Michael C. Dorneich, Caroline Krejci, Linda Shenk, Ulrike Passe

Industrial and Manufacturing Systems Engineering Conference Proceedings and Posters

This work surveyed residents of an economically disadvantaged community on their attitudes toward weatherization and their energy use behaviors. To support urban leaders making decisions to mitigate the effects of large-scale climate change, data-driven simulation models are being developed. To ensure that these models are equitable, the needs of all citizens must be included, especially those most vulnerable to the impacts of climate change. The results of this survey indicate that residents are taking steps to weatherize and conserve energy, but they are hindered by a lack of resources and knowledge of available assistance programs. These results are being applied ...

Solar & Rain Catching Canopy "Urban Oasis" 1.1, Afolabi Ibitoye, Alexander Aptekar

Publications and Research

Accumulation of water runoff during rain storms affects New York City’s combination water system, forcing water treatment plants to release untreated excess water. Rather than allow this grey water to overfill the sewer system, pocket parks and gardens can be used to absorb rainfall. By harnessing nature’s resources through today’s technology we can also create solar and rain catching canopies to beautify, educate, and bring growth and social awareness to local businesses.

In order to design the canopies to collect the maximum amount of rainwater and maximize solar collection, we analyzed expected rainfall and optimal solar angles ...

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 ...

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 ...


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 ...

City Play: Post-Affordances And The Transformative Power Of Place, Benjamin A. Shirtcliff, Mahsa Adib Mar 2018

City Play: Post-Affordances And The Transformative Power Of Place, Benjamin A. Shirtcliff, Mahsa Adib

Landscape Architecture Conference Proceedings and Papers

Landscape architecture research and practice often focus on demand or instrumental value of the land to serve some need, like a healing garden or playground, or the intrinsic value of the land due to unique characteristics, like a protected wilderness or geological phenomenon, but rarely does the discipline concentrate on the transformative power of the environment. Sarkar (2012) suggests that transformative power refers to those unanticipated experiences with the environment that change or transform our worldview.

Analyses Of Crowd-Sourced Sound Levels Of Restaurants And Bars In New York City, Gregory S. Farber, Lily M. Wang

Architectural Engineering -- Faculty Publications

For several decades, there has been a significant need to better educate the public about noise pollution. A small number of small-scale studies have focused on the sound levels of restaurants and their impact on health and hearing. There have also been an increasing number of media articles stating that eating and drinking venues are getting increasingly loud making it more difficult for people to connect with others in conversation. This study reports on an exploratory large-scale noise survey of sound levels of 2,376 restaurants and bars in New York City using a novel smart-phone application and categorized them ...

Investigating The State Of Play Of Geobim Across Europe, Claire Ellul, Jantien E. Stoter, Lars Harrie, M. Shariat, Avril Behan, Maria Pla

Conference papers

In both the Geographic Information (Geo) and Building Information Modelling (BIM) domains, it is widely acknowledged that the integration of data from both domains is beneficial and a crucial step in facing the multi-disciplinary challenges of our built environment. The result of this integration – which can broadly be termed GeoBIM – could answer questions such as identifying an appropriate Heating, Ventilation and Air Conditioning system for a building based on room usage, outside air temperature, solar exposure and traffic pollution or validating whether a proposed built asset meets relevant planning constraints.

Developing a coherent approach to GeoBIM integration requires consensus between ...


What Design Practices Do Professionals Use For Sustainability And Innovation?, Jeremy Faludi, Alice M. Agogino Jan 2018

What Design Practices Do Professionals Use For Sustainability And Innovation?, Jeremy Faludi, Alice M. Agogino

Open Dartmouth: Faculty Open Access Articles

Interviews with 27 professionals were performed to investigate what designers, engineers, and their managers value in sustainable design practices, and see how sustainable design practices might also provide innovation. Quantitative and qualitative analysis found that only 1/6th of design practices were valued for both sustainability and innovation; two often-mentioned practices were systems thinking and The Natural Step. Providing a new lens, broadening scope, and problem redefinition were some of the reasons these and other design practices were valued for both sustainability and innovation.


Numerical Simulation Of Fault Impacts For Commercial Walk-In Freezers, Alireza Behfar, David P. Yuill Jan 2018

Numerical Simulation Of Fault Impacts For Commercial Walk-In Freezers, Alireza Behfar, David P. Yuill

Architectural Engineering -- Faculty Publications

Refrigeration systems can undergo many faults that could negatively affect their operation and performance. This paper describes a modeling process to simulate the fault impacts on the operation of a commercial walk-in freezer using semi-empirical models. These models often require less modeling effort than full forward models and could be used in scenarios where detailed information is missing, such as in field-measured systems. An important characteristic of a typical walk-in refrigeration system is the existence of a liquid-line receiver after the condenser, which significantly changes the behavior of the cycle, in comparison to a receiver-less system. Component models described in ...


Impact Of Owners’ Early Decisions On Project Performance And Dispute Occurrence In Public Highway Projects, Sogand Hasanzadeh, Behzad Esmaeili, Ghada M. Gad, Douglas D. Gransberg Jan 2018

Impact Of Owners’ Early Decisions On Project Performance And Dispute Occurrence In Public Highway Projects, Sogand Hasanzadeh, Behzad Esmaeili, Ghada M. Gad, Douglas D. Gransberg

Architectural Engineering -- Faculty Publications

Disputes are common in the construction industry and lead to unnecessary cost and schedule overruns in projects. It is commonly believed that owners’ early decisions regarding the selection of delivery methods, procurement methods, and contract types impact the frequency and severity of project disputes; however, no previous study has empirically tested this hypothesis, particularly in highway public projects. Therefore, this study empirically investigated the impact of owners’ early decisions regarding project organization (i.e., delivery methods, procurement, and contract types) on performance measures (e.g., cost and schedule growth), specifically dispute performance metrics (e.g., frequency and severity of disputes ...
