Evaluation Of Sustainable And Environmentally Friendly Stabilization Of Cohesionless Sandy Soil For Transportation Infrastructure, Miladin Radovic, Anand Puppala, Surya Sarat Chandra Congress, Jungyeon Jang, Oscar Huang

Data

Ordinary Portland cement (OPC) is generally used to stabilize cohesionless sandy soils that are often found in coastal areas. Due to its high carbon footprint, many studies are being conducted to identify a suitable green alternative for stabilizing cohesionless soils. Previous studies have shown that partially replacing OPC with waste materials such as nano-silica and coal waste reduces the overall carbon footprint without significantly impacting the performance. Geopolymer (GP) received a lot of attention in the past few decades owing to its similar properties to that of OPC yet with a lower carbon footprint. This study investigated the feasibility of …

Assessment Of The Potential Of Self-Incorporation As A Solution To Roadway Maintenance In Texas Colonias, Moise Dzogolo

Public Affairs Theses

Colonias are communities that lack basic infrastructures such as water, sewer, and paved roads and that are located within 100 miles of the US-Mexico border. They are generally found in unincorporated areas, and the literature, as well as policy makers, have extensively called for their annexation as a solution to solve the infrastructure issues. This paper examines selfincorporation as an alternative to annexations as cities have consistently avoided colonias when they expand through annexation. The paper has two focuses. The first one consists of analyzing the economic and social aspects of a colonia to determine whether they resemble the ones …

Resource Allocation And Capacity In Wireless Communications And Networks, Zikai Wang

Electrical Engineering Dissertations

How to allocate resources in the era of Big Data in telecommunications becomes a new issue. Smartphone data could be a function of personality, as the smartphone supports interpersonal interaction, and the data collected from the smartphone usage often contains rich customer opinion and behavioral information. A bandwidth allocation method based on smartphone users' personality traits and channel condition is studied in a unified mathematical framework in this dissertation. Personalizing bandwidth allocation could be done by analyzing smartphone users' personality traits, resulting in business intelligence, a smarter and more efficient usage of the limited bandwidth, while taking channel fading conditions …

Eco-Friendly Stabilization Of Sulfate-Rich Expansive Soils Using Geopolymers For Transportation Infrastructure, Xinbao Yu, Anand Puppala, Miladin Radovic, Sayantan Chakraborty, Jungyeon Jang, Oscar Huang

Data

Traditional calcium-based stabilizers, such as lime, to stabilize sulfate-rich expansive soils, are lasting-challenges in geotechnical engineering. The biggest problem with using calcium-based stabilizers is that when calcium and water are exposed to sulfate-rich expansive soils, they form ettringite as an expansive mineral, which causes sulfate-induced heaving. The study aimed to investigate the feasibility of stabilizing sulfate-rich expansive soils using geopolymers for transportation infrastructure. Literature review on sulfate-induced heaving and sulfate-rich soils stabilized with geopolymers suggests a direction for how to stabilize sulfate soils using geopolymers. The engineering tests were conducted to determine the swell, shrinkage, and strength behavior of natural, …

Development Of Geopolymer-Based Cement And Soil Stabilizers For Transportation Infrastructure, Miladin Radovic, Anand Puppala

Data

Corresponding data set for Tran-SET Project No. 18CTAM03. Abstract of the final report is stated below for reference:

"Geopolymer Cement (GPC) has drawn much attention in the recent years as an alternative to Ordinary Portland Cement (OPC) for soil stabilization, pavements, bridges and other transportation structures due to their good mechanical properties in comparison to OPC. In addition, GPC can be processed at room temperatures from aqueous solutions of waste materials (e.g. fly ash) or abundant natural sources (e.g. clay), thereby significantly reducing CO2 production associated with processing of OPC. As such, GPC proves to be a more sustainable and …

Novel Infrastructure Monitoring Using Multifaceted Unmanned Aerial Vehicle Systems - Close Range Photogrammetry (Uav - Crp) Data Analysis, Surya Sarat Chandra Congress

Civil Engineering Dissertations

Remote sensing is a method of collecting data without making any physical contact with the object under inspection. Modern day remote sensing kicked off with the invention of the camera and continued on to the invention of advanced satellite mounted sensors. Photogrammetry is defined as a science that measures distances using one or more images captured remotely. Remote collection of images within a range of 1000 ft is termed close-range photogrammetry (CRP). Unmanned aerial vehicle systems (UAV or UAS) have become a popular means of remotely gathering information and assessing infrastructure conditions due to their versatile nature. Multirotor and fixed-wing …

An Investigation Of Water Pipeline Renewal Practices, Abbas Abed Salman

Civil Engineering Theses

Globally, the use of trenchless technologies is gradually increasing due to the growing need to replace and renew aging utility infrastructure and the need for more flexible solutions for the installation of new pipes. In the United States of America, the American Society of Civil Engineers (ASCE) in 2017 assessed that America’s infrastructure is close to failing. It faces an annual shortfall of at least $11 billion to replace the aging facilities that are near the end of their useful lives. In this research, surveys and interviews of professionals working in trenchless technologies for the North American Society for Trenchless …

Fading Landscapes: The Culture Of Exile And The Open Road, Marc T. Rentschler

English Department: Traveling American Modernism (ENG 366, Fall 2018)

This article seeks to analyze the complex relationship between material culture and hegemonic constructions of ideology along with their tendency to make their way into larger institutional apparatuses of society. For this study this interaction is explored through the symbolic construction of the american roadways and a selective. Drawing on Jack Kerouac’s On the Road, Baudrillard’s America, and William Least Heat Moon’s Blue Highways, this work attempts to combine critical perspectives on the formation of public space with the events of these works in order to formulate how the ideological values which are subsumed by the representational space of ‘The …

Development Of A New Joint System For A Circular-Shaped Infrastructure, Sugyu Lee

Civil Engineering Dissertations

This dissertation focused on development of new carbon fiber joint systems for all types of underground gravity and sewer pipe systems. Specifically, the external CFRP wrap and, particularly, the carbon fiber reinforced polymer (CFRP) internal coupler can be used for concrete pipes with regular or reduced wall thicknesses. The concrete pipes with reduced wall thickness are classified as semi-rigid pipe and are referred to as thin-wall (TW) concrete pipe. The performance of the CFRP coupler is presented in this report based on full-scale experimental tests and three dimensional non-linear finite element studies for regular and thin wall pipes. Finally, design …

The Effect Of Educational, Health, Infrastructure Expenses On The Workforce Employment And Poverty, Niken Sulistyowati

BISNIS & BIROKRASI: Jurnal Ilmu Administrasi dan Organisasi

The research aims to analyze the influence and impact of educational, health, and infrastructure expenses on the employment of workforce (from agricultural, industrial, services sectors) and poverty in Central Java. The model was built by using an econometric approach in the form of a system of simultaneous equation model consisting of six blocks (human capital, inputs, outputs, revenues, expenditures and social welfare) with 33 equations (24 structural equations and 9 identity equation). The method of estimation model uses Two Stage Least Squares (2SLS). The simulation results show that the policies of increasing expenses on education, health, and infrastructure with the …
