Development Of Composite Pcms By Incorporation Of Paraffin Into Various Building Materials, Shazim Ali Memon, Wenyu Liao, Shuqing Yang, Hongzhi Cui, Syed Farasat Ali Shah

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

In this research, we focused on the development of composite phase-change materials (CPCMs) by incorporation of a paraffin through vacuum impregnation in widely used building materials (Kaolin and ground granulated blast-furnace slag (GGBS)). The composite PCMs were characterized using environmental scanning electron microscopy (ESEM), Fourier transform infrared spectroscopy (FT-IR), differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) techniques. Moreover, thermal performance of cement paste composite PCM panels was evaluated using a self-designed heating system. Test results showed that the maximum percentage of paraffin retained by Kaolin and GGBS was found to be 18% and 9%, respectively. FT-IR results show that …

Precipice Regulations And Perverse Incentives: Comparing Historic Preservation Designation And Endangered Species Listing, J. Peter Byrne

Georgetown Law Faculty Publications and Other Works

The insight upon which this article is built is that the common structures of these two legal regimes create incentives toward destroying the resources they seek to protect. The shift from legal freedom to exploit resources to strict limitation on property modification and the lengthy and public process to designate or list specific resources for protection provide the motive and the opportunity to legally frustrate the application of the statutes. This article seeks to understand how these perverse incentives are created and how they can be lessened. The procedural and substantive provisions of both legal regimes have evolved to reduce …

Efficient Management Of Cross-Cultural Manufacturing Teams In The Dominican Republic, Efrain Serrano

Walden Dissertations and Doctoral Studies

Companies that have moved their operations from the United States to other countries have forced top management to rely on their managers for leading overseas assignments. However, the success rate of expatriate managers is low and is a concern for top management in corporations. The purpose of this phenomenological study was to explore the shared lived experiences of 20 expatriate managers to identify methods which may improve the success rates of expatriate managers asked to participate in overseas assignments. Social learning, cultural shock, and experiential learning were used to support the conceptual framework linking how cross-cultural training, adaptation, problems, and …

The City As Palimpsest, Jeffrey A. Kroessler

Publications and Research

“Palimpsest preservation” suggest the necessity of keeping the successive layers of urban form alive rather than simply effacing and rebuilding, for that keeps a city’s history alive. No city without a tangible, tactile history, without the capacity for denizens and visitors to reach into the past while experiencing the present, can be truly vital. But this is a contested approach. George Orwell’s 1984 offers a warning in the guise of a party slogan: “Who controls the past controls the future: who controls the present controls the past.” Preservationists may advocate on historical, architectural, or cultural grounds, but the final decision …

Shared Trauma: A Phenomenological Investigation Of African American Teachers, Juanita Lynne White

Walden Dissertations and Doctoral Studies

In the wake of increasing community disasters such as hurricanes, neighborhood violence, and terrorist attacks, schools are usually deemed places where youth can find safety and stability. Research about community trauma related to the role of teachers and schools has predominantly focused on younger populations, concerned about disturbances in their developmental processes. School teachers' responsibilities related to these community disasters have also increased and now include supporting their traumatized students. However, there has been limited attention on the direct effect of community traumas on the teachers who work and live in affected districts. The construct of shared trauma describes this …

The Cost Of Design: A Life-Cycle Assessment Of Green Infrastructure Technology, Cheryl Kaye Lough

LSU Master's Theses

Landscape architectural research of green infrastructural practices has increased dramatically over the last decade. Due to this research, many designers are suggesting some form of green infrastructure within their projects. Much of the present-day research focuses on function and not long term impacts of individual materials. The current rate of implementation of green infrastructures might not produce a drastic impact upon the environment, but with installations being realized at an ever-increasing and larger scales, even minute elements within the construction of these structures begin to influence the overall ecological footprint produced by our designs. Designers must re-evaluate the materiality of …

New Orleans, A City Of Layers Preventing Extinction, William Francis Reinhardt

LSU Master's Theses

Preventing the loss of New Orleans occupies the minds of many designers in Louisiana. Great efforts to preserve the city are targeting the slow return to naturalization of the engineered river to find a new balance determined by plan formulators of the Federal government. Throughout history, many experimental movements have been born from the landscape architecture practice, and may be key to the future of New Orleans. Separate chapters are devoted towards the movements created by William Kent, Fletcher Steele, and Jens Jensen to explore as inspiration to be applied to coastal living. Finally, the future of New Orleans is …

Using Stormwater Modeling In Iterative Site Design: An Integration Of Techniques From Engineering And Landscape Architecture, Brooke Erin Morris

LSU Master's Theses

Landscape Architects currently do not have an efficient method for including stormwater quantities in early stages of their design process. With stormwater control infrastructure and theory rapidly shifting in favor of stormwater management with Green Infrastructure or Low Impact Development technologies (LIDs), landscape architects and planners are increasingly making layout and sizing decisions for stormwater design. Due to the development of modeling tools, it is now possible to rapidly produce quantifiable stormwater values for complex site designs at a range of scales. This paper proposes a methodology for the utilization of the EPA – Stormwater Management Model (SWMM), in conjunction …

Failure Modes For I-Section Gfrp Beams, Mamadou Konate, Zia Razzaq

Civil & Environmental Engineering Faculty Publications

This paper presents calculations for the failure modes for I-section Glass Fiber Reinforced Polymer (GFRP) beams with single mid-span web brace. Theoretical predictions are made using ASCE-LFRD Pre-Standard for FRP structures. For the member length considered, it is found that for small and medium I-sections the failure mode is governed by lateral-torsional buckling and for bigger I-sections the failure mode is governed by material rupture. The outcome of the predicted lateral-torsional buckling mode is compared with that observed experimentally.

Revisit And Revise: The Introspective Approach To Reclamation And Redevelopment In Miami's Urban Core, Jescelle Renee Major

LSU Master's Theses

The human plays a vital role in the city and the city a vital role in the sustainability and resiliency of the future. It is imperative to explore all avenues for improvement and longevity. Now is the time to explore methods to strengthen the cities we have and the people who live there. This is especially true for coastal cities facing sea level rise and climate change. It is important now not to dwell on what we have lost but to seek methods for using the memory of a place to restore and build for the future. Recognizing there is …

Informal Landscape Architecture: A Tool To Improve Water Quality For Informal Settlements Along Waterways In Bangkok, Jidapa Chayakul

LSU Master's Theses

The canals of Bangkok were a vital form of infrastructure from when the city was founded in 1782 until the 1850s, when the road system was introduced. Built for agricultural irrigation, the canals served as the primary means of transportation and significantly influenced the form and orientation of Bangkok’s early settlements and public institutions. With the implementation of roads, new buildings were constructed to be oriented towards the streets and away from the canals. The canals and their communities subsequently decreased in visibility. Today, most of the land along the waterways is publically owned. As a result, the land adjacent …

Campus Planners' Preferences For Residence Hall Project Delivery Methods, Paul E. Riel

Ridazz, Wrenches, And Wonks: A Revolution On Two Wheels Rolls Into Los Angeles, Donald Parker Strauss

Antioch University Dissertations & Theses

How can we make cities more livable? Los Angeles, in particular, is a notably challenging place to live. For many, it is hard to see Los Angeles—city or county—as anything other than a huge, sprawling, and some would say placeless place. Los Angeles is known by many as the place that tore up more than 1,000 miles of streetcar lines to make way for millions of cars and hundreds of miles of freeways. Because of this, Los Angeles is also known for its poor air quality and jammed freeways. Those who live in Los Angeles know that it can be …

Creativity In Urban Placemaking: Horizontal Networks And Social Equity In Three Cultural Districts, Tom Borrup

Antioch University Dissertations & Theses

Many authors point to expanding disparities related to wealth and social benefits brought by globalization and the creative city movement while culture and creativity emerge as growing forces in urban placemaking and economic development. The phenomenon of cultural district formation in cities around the globe presents challenges and opportunities for leaders, planners, and managers. Emerging theory related to cultural districts suggests culture can serve to build horizontal relationships that bridge people and networks from different sectors and professions as well as across ethnicities, class, and interests. Research for this dissertation examined the formation of three urban cultural districts social and …

Seeing Red: Characterizing Historic Bricks At Sylvester Manor, Long Island, Ny 1652-1735, Martin John Schmidheiny

Graduate Masters Theses

The goal of this project is to develop a basic material characterization of the bricks excavated at the site of Sylvester Manor on Shelter Island, New York. In the early Manor period of 1650-1690, this early Northern provisioning plantation supplied Barbadian sugar operations and pursued mercantile interests independent of state control. Accounting for the range of production defects and material characteristics of the bricks suggests on-site or local manufacture as a regional ceramic industry developed. Qualitative visual analysis and petrographic thin-sections were used to characterize the internal composition, variation and production evidence in the bricks. Interpreting the results of this …

A Sustainable Design Method Acting As An Innovation Tool, Jeremy Faludi

Dartmouth Scholarship

Product companies generally see sustainability as a burden limiting their design process, similar to cost or safety limits. A method for sustainable design was created, attempting to turn sustainability from a burden into an innovation tool with inherent business value. The method combines creative whole-systems thinking with quantitative sustainability metrics. It facilitates innovation by the creation of visual whole-system maps that encourage more thorough and more radical brainstorming. It facilitates sustainability by using quantitative measurements, such as lifecycle assessment or point-based certification systems, to set priorities and choose final designs. The method has been anecdotally tested in classes at four …
