All Graduate Theses and Dissertations
Structural Health monitoring is to determine the condition of a bridge based on instrument measurements. The C-846 Bridge in Salt Lake City has such instrumentation. The bridge is located in Salt Lake City at about 2100 South and Interstate 15. This bridge has two kinds of instruments on it: accelerometers and thermocouples. The accelerometers measure the vibrations of the bridge. The accelerometers have been recording data on the bridge since 2001. The thermocouples, which measure temperature, were added as part of this thesis in April 2016.
In light of recent research, damage may be detected from measuring the change in ...
A New Market Segmentation Approach: Evidence From Two Canadian Cities, 2017 McGill University
A New Market Segmentation Approach: Evidence From Two Canadian Cities, Dea Van Lierop, Ahmed El-Geneidy
Journal of Public Transportation
Traditionally, transit market research has categorized passengers into two distinct groups: captive riders and choice riders. Market analyses that depend on such broad categories are likely to overlook important details about the needs and desires of their customer base. This study attempts to better understand the complexities of the different groups who take transit by using information from five years of customer satisfaction questionnaires collected by two Canadian transit providers. Employing a series of clustering techniques, the analysis reveals that nine market segments are present across different modes in both transit agencies. Three different overarching groups of transit users are ...
A Framework For Measuring The Spatial Equity In The Distribution Of Public Transportation Benefits, 2017 Isfahan University of Technology
A Framework For Measuring The Spatial Equity In The Distribution Of Public Transportation Benefits, Seyyed Amir Hosein Mortazavi, Meisam Akbarzadeh
Journal of Public Transportation
This paper proposes that an equitable transit system requires that the geographical distribution of transit service benefits conform to the geographical distribution of the citizens with the greatest need for public transportation. This is the essence of vertical equity. This study calculated “connectivity power,” which reflects public transit service quality in each traffic analysis zone (TAZ) in a city to indicate the amount of benefit that TAZ is receiving from the transit system. The number of carless citizens in each TAZ was also calculated as an index of need to the public transit services in that area. Conformity of need ...

Identifying Key Factors Of Rail Transit Service Quality: An Empirical Analysis For Istanbul, Erkan Isikli, Nezir Aydin, Erkan Celik, Alev Taskin Gumus
Journal of Public Transportation
Providing a high quality of service in public transportation is essential to reduce dissatisfactions stemming from traffic congestion and noise. Public transport providers need to find ways to dilute the effects of immoderate use of private cars in big cities while maintaining a sufficient level of customer satisfaction. This study aimed to identify the key service quality (SQ) factors that drive passenger satisfaction in Istanbul’s rail transit (RT) system using data obtained from an extensive survey conducted by the Istanbul Public Transportation Co. A total of 11,116 passengers who used rail transport from May 15–June 3, 2012 ...
The Irreversible Momentum Of Clean Energy, 2017 President of the United States
The Irreversible Momentum Of Clean Energy, Barack Obama
US Department of Energy Publications
The release of carbon dioxide (CO2) and other greenhouse gases (GHGs) due to human activity is increasing global av-erage surface air temperatures, disrupting weather patterns, and acidifying the ocean (1). Left unchecked, the continued growth of GHG emissions could cause global average tem-peratures to increase by another 4°C or more by 2100 and by 1.5 to 2 times as much in many midcontinent and far northern locations (1). Although our understanding of the impacts of climate change is increasingly and disturbingly clear, there is still debate about the proper course for U.S. policy—a debate that is ...

Increased Indigenous Participation In Environmental Decision-Making: A Policy Analysis For The Improvement Of Indigenous Health, Kerry Black, Edward Mcbean
The International Indigenous Policy Journal
Improving the physical environment and Indigenous participation in environmental decision-making is inherently related to the improvement of health among Indigenous Peoples. Improving the state of the physical environment necessitates increased involvement by Indigenous communities in decision-making and policy development. This involvement must integrate local traditional knowledge (TK) as an important tool in the decolonization of environmental decision-making, and a necessary step towards the improvement of Indigenous health. With a focus on the physical environment as a social determinant of Indigenous health, this article highlights the need for increased Indigenous participation in the decision-making process on environmental issues and proposes a ...
Landfill Elevated Internal Temperature Detection And Landfill Fire Index Assessment For Fire Monitoring, Aurora Musilli
Theses and Dissertations
Landfill fires are becoming a real threat to both people and environment due to lack of predictions and control methods. Processing of the infrared band from level-1 satellite images was employed and decades worth of archived data from USGS Earth Explorer databases were analyzed to obtain surface temperature values of Atlantic Waste Landfill, Virginia and Bridgeton Landfill, Missouri. Multitemporal thermal maps and frequency of maxima analysis maps of these two landfills showed the hotspots spreading through the waste site. A Landfill Fire Index (LFI) was created by investigating eight factors that give information about the hazardousness of the landfill conditions ...

Numerical Computation Of Transient Response Of 2d Wedge Impact, 2016 University of New Orleans
Numerical Computation Of Transient Response Of 2d Wedge Impact, Naresh Kumar Koyyapu
University of New Orleans Theses and Dissertations
The diverse applications of advanced marine craft ascribed to their high speed and technological advancements has led to the use of stronger and lighter metals in such crafts. High speed, in effect also increases slamming loads as higher speed increases frequency of wave encounter while operating in waves. The present study is limited to wedge impact models. Fundamentally, the study is thus about two-dimensional (2D) wedge impact in water. In an attempt to predict the structural response to impact hydrodynamic force, a beam element based finite element (FE) computer program is written and the results of the code are presented ...
Investigation Of Grouted Dowel Connection For Precast Concrete Wall Construction, 2016 The University of Western Ontario
Investigation Of Grouted Dowel Connection For Precast Concrete Wall Construction, Douglas J. Provost-Smith
Electronic Thesis and Dissertation Repository
The grouted dowel connection is a simple and cost-effective connection used in many precast concrete structural systems. The required dowel length is currently designed as a regular bar in reinforced concrete, which underestimates the bond strength, thus resulting in excessive connection lengths. Furthermore, precast wall construction continues throughout cold weather, where in-situ heating of the grout used in the grouted dowel connections is usually conducted for short periods of time. Hence, early-age exposure to subfreezing conditions may affect the quality of the grout and subsequently the bond strength of the connection, which can compromise structural integrity.
In this thesis, full-scale ...
An Evaluation Of The Safety Of The Cycling In Dublin City For Dit Students, 2016 Dublin Institute of Technology
An Evaluation Of The Safety Of The Cycling In Dublin City For Dit Students, Niamh O. Reilly
Cycling as a mode of transport offers many benefits including a cheap, cost effective, healthy, fast, mainly congestion free and environmentally friendly means of getting to and from places of employment and education. Given the central location of Dublin Institute of Technology campus buildings this would seem an ideal option for its third level students, but on the contrary, a DIT online travel survey conducted in March 2014 found that only 7% of students chose cycling as their primary mode of transport. Concerns about cyclist safety were a major factor cited by students who chose alternative modes of transport. Based ...

Increasing The Success Rate Of Groundwater Exploration In Developing Nation Using Geophysical Methods: Case Of A Small Community In Nigeria, 2016 Indiana University - Purdue University Fort Wayne
Increasing The Success Rate Of Groundwater Exploration In Developing Nation Using Geophysical Methods: Case Of A Small Community In Nigeria, Solomon A. Isiorho, David O. Gbenga, P A. Aizebeokhai
Geosciences Faculty Presentations
About 35 percent of Nigeria’s population of the more than 180 M relies on groundwater. Due to the lack of an adequate water supply system within Ogun State, many homes result to drilling their own private wells. Most groundwater is sourced from shallow wells (less than 30 m) and is often of poor water quality. The number of borehole failures is also alarming. Several entrepreneurs have seized on the lack of adequate water supply to drill for groundwater. Several of these wells have either failed or are not adequate for the purposed use of the water. There also appears ...
Concentrations Of Lead In Germany's Tap Water, 2016 Loyola Marymount University
Concentrations Of Lead In Germany's Tap Water, Kirby E. Townsend
Research & Exhibition
Germany is known for having great tap water. However, since it is an older country, in certain homes and buildings lead piping still exists, and many people are not even aware of this. Because of these pipes, lead can seep into the tap water and have negative impacts on one’s health. This is why I want to measure concentrations of lead in tap water in different areas of Germany to see where lead may be a concern.
