Bitcoin's Technical Foundation And Its Potential For A Decentralized And Environmentally Friendly Future, Iqtiar Md Siddique

Open Access Theses & Dissertations

This research examines a systematic analysis of Bitcoin, employing a Coefficient of Variation (CV) approach to gauge its degree of decentralization. Bitcoin, an innovative decentralized digital currency, has received much attention for its potential to revolutionize traditional financial systems. This study employs the Coefficient of Variation (CV) to acquire insights into the wealth distribution and concentration among Bitcoin users. This research demonstrates how decentralized the network of Bitcoin is. The methodology uses real data on Bitcoin addresses and their holdings to compute the Coefficient of Variation (CV). This approach provides valuable insights into the ongoing discourse surrounding Bitcoin's decentralization, offering …

Transportation Asset Management For The Electric Road System, Kamalen Maria Santos Diaz

Open Access Theses & Dissertations

Electric road systems (ERS) have been presented as a new solution towards a sustainable transportation future, fueling the widespread adoption of electric vehicles by eliminating range anxiety, reducing battery size, and being regional friendly. These systems consist of four components: electric power supply, roads, vehicles, and operations. Much of the early research conducted on ERS has been on how to initially construct these systems by focusing on the first three components, however, there is limited knowledge on how ERS will impact traditional road operations after the systems are in place. Transportation Asset Management (TAM), a major focus within the transportation …

Understanding The Consequences And Costs Of Climate Change On Texas Pavements, Megha Sharma

Open Access Theses & Dissertations

Over the several centuries, the global temperatures have been rising, and the rate of rising in temperature has increased significantly in the last century. The increase in temperature and precipitation can substantially influence performance life of pavements because of their continuous exposure to climate. The climate parameters like temperature and precipitation are considered in the pavement design to reflect the influence of climate factors on the performance of the pavements. Currently, designers use the historical weather patterns while designing pavements. Since the climate is changing, the estimated service life of the pavement will be reduced significantly if the historical data …

A Multi-Objective Sustainable Model For Transportation Asset Management Practices, Marketa Vavrova

Open Access Theses & Dissertations

Transportation Asset Management (TAM) practices have gained popularity in the United States and worldwide with the aim to provide the required level of service for the transportation infrastructure network in the most cost-effective manner. However, TAM is a complex decision-making process because many objectives and different perspectives, often producing conflicting goals, must be considered.

This Dissertation presents a Multi-Objective Sustainable (MOS) model to integrate economic, social, and environmental sustainable objectives into TAM decision-making. The objective is to develop a holistic multi-objective asset management approach integrating environmental and social sustainability related performance measures with traditional indicators, such as asset condition and …

Integrated Sustainability Decision-Making Framework, Michael Paul Cole

Open Access Theses & Dissertations

The Integrated Sustainability Decision-Making Framework (ISDMF) is an 'ideal case' framework developed at the University of Texas El Paso (UTEP) from 2012 to present to provide the most comprehensive and concise sustainability strategy and decision-making template available.

Sustainable decision-making improves community Quality of Life, but is often beyond the reach of the majority. A framework that is most approachable, actionable, and adoptable can accelerate convergence on and continued operation of a sustainable solution. Research confirms that published frameworks continuously emerge, and are infinite in number. Iterations benefit from prior work, and contribution occurs when an 'ideal case' is envisioned, best …

Critical Parts Retrieval And Profit Maximization For Medical Sustainability Using Design For Disassembly And Modularity, Karthik Varma Manikanta Koppella

Open Access Theses & Dissertations

With rising medical expenditure and increase in medical waste, it is highly imperative to look for ways to recycle and reuse medical products. Even though the reprocessing industry has made use of optimum disassembly techniques in order to derive the maximum possible profit from each medical device, it is limited since most of the medical devices can be hard to recycle without a change in the basic design complying with life cycle goals. This study will introduce a framework which will help to combine the optimum disassembly techniques with the modularity concept in order to come up with recommendations for …
