Surface Water Hydrology Within The Great Salt Lake Basin, Madeline F. Merck

All Graduate Theses and Dissertations, Fall 2023 to Present

The Great Salt Lake (GSL) and its tributaries are ecologically and economically important resources for Utah. It is a highly saline lake, with salinity that is several times saltier than the ocean. Lake uses are heavily influenced by its salinity and lake level and, similarly, river uses by its streamflow quantity. Currently, the GSL Basin is experiencing changes that affect tributary inflows, lake level, and salinity. For my dissertation and in support of better lake management, I addressed important gaps in our understanding of the lake and the changes it is undergoing.

Chapter 2 is an examination of the distribution …

Podcasts As A Learning Method In Engineering Education, Jeanette Engzell, Charlotte Norrman

Research Papers

Multimedia has been integrated in education the last 40 years but podcasts have more recently become popular. Since 2006 podcasts have become increasingly popular in Sweden and nowadays podcasts are used in all types of contexts but are yet to find a place in engineering education. Students do not acquire knowledge or solve problems in the same way. Using a mix of methods in teaching is therefore important if one has the ambition to democratize the learning processes and give students the same opportunity to learn. Traditionally, much of the university education has been based on lectures in classrooms and …

Probabilistic Cable Aging Diagnosis And Prognosis With Reflectometry And Capacitance Methods, Xuan Wang

Theses and Dissertations

Safe and reliable operation of power plants and power transmission are critical to economy and society. Cables in power generation and transmission are subject to various thermal, chemical, and mechanical stresses, which generally lead to aging and degradation of cable insulation. It is reported that some cables with a projected lifetime of 40 years need to be replaced in 10-15 years. Poorly maintained aged cables can adversely affect power delivery and lead to catastrophic events, such as blackout, fires, and loss of lives. The current research on cable is mainly focused on the detection and localization of hard faults, which …

The Influence Of Environmental Tax And Technology On Different Air Pollution Emissions In Oecd Countries, Malak Ali Assaf

BAU Journal - Creative Sustainable Development

Although countries continuously employ taxation and technological measures to control air pollution in the Organization for Economic Co-operation and Development, the results of these practices should be evaluated to determine whether they reach their intended outcomes. This study used panel autoregressive distributed lag model to establish how environmental taxes and technology affects the emission of air pollutants (nitrogen oxides, Carbon dioxide, and particulate matter 2.5). Using secondary data present in the OECD Database and The World Bank, EViews panel was derived to create 3 model in which each of the three variables would be sufficiently explained by environmental tax, abatement …

Architectural Hybrid (Physical-Digital) Prototyping In Design Processes With Digital Twin Technologies, Gulbahar Emir Isik, Henri Achten

Architecture and Planning Journal (APJ)

A digital twin is a simultaneous digital reflection of object processes and states. Digital twins are usually made of objects that exist in reality or which are very near completion in a design and production process. In our research, we investigate the potential of digital twin technology for early design. Key to the early application of digital twin in design is the role of information and simulation. Since design information is valuable for predicting the future of design, we assume that design will begin to change as digital twin technologies become more and more adaptable, as designers simultaneously have digital …

Drone Detection Using Yolov5, Burchan Aydin, Subroto Singha

Faculty Publications

The rapidly increasing number of drones in the national airspace, including those for recreational and commercial applications, has raised concerns regarding misuse. Autonomous drone detection systems offer a probable solution to overcoming the issue of potential drone misuse, such as drug smuggling, violating people’s privacy, etc. Detecting drones can be difficult, due to similar objects in the sky, such as airplanes and birds. In addition, automated drone detection systems need to be trained with ample amounts of data to provide high accuracy. Real-time detection is also necessary, but this requires highly configured devices such as a graphical processing unit (GPU). …

Electrochromic Smart Glass: Supplier Comparison Return On Investment Analysis, Hayden Stewart Owens

Construction Management

In recent years, sustainability in construction has become the focus of how the industry can progress with minimal environmental impact. As sustainability certifications become more desirable, key companies in the construction industry have started to seek greener alternatives to standard building systems. There are many sustainable products that are released, but these products are typically so complex that members of the industry are not familiar with these new systems. One novel piece of technology introduced to the industry is electrochromic glass, or smart glass. Electrochromic glass windows examine sunlight and heat exposure from the surrounding environment and change their opacity …

Artificial Intelligence Assisted Residual Strength And Life Prediction Of Fiber Reinforced Polymer Composites, Partha Pratim Das, Muthu Ram Prabhu Elenchezhian, Vamsee Vadlamudi, Rassel Raihan

Institute of Predictive Performance Methodologies (IPPM-UTARI)

With the increased use of composite materials, researchers have developed many approaches for structural and prognostic health monitoring. Broadband Dielectric Spectroscopy (BbDS)/Impedance Spectroscopy (IS) is a state-of-the-art technology that can be used to identify and monitor the minute changes in damage initiation, accumulation, interactions, and the degree of damage in a composite under static and dynamic loading. This work presents a novel artificial neural network (ANN) framework for fiber-reinforced polymer (FRP) composites under fatigue loading, which incorporates dielectric state variables to predict the life (durability) and residual strength (damage tolerance) from real-time acquired dielectric permittivity of the material. The findings …

Communicating Complexity To Prepare For Complexity, Magnus Lilledahl

Practice Papers

A trend in higher education is a stronger focus on the content of a study program as a whole rather than the individual courses that make up the program. The Norwegian university of science and technology (NTNU) has recently completed a large project, The future of technology studies (FTS), that attempt to describe how study programs should prepare students for a technological career in a rapidly evolving society. A central recommendation from the project is the necessity of an integrated, programdriven curriculum. Hence, there is a need for a useful description of the content at the program level. However, a …

Integrating Ar Technology Into Cbm Laboratory Experiments, Alan Mcdonnell, Brian Vaughan, David Mcdonnell, Bernard Capraro

Practice Papers

This paper examines the pilot phase integration of Augmented Reality (AR) technology into a Condition Based Monitoring (CBM) engineering taught module. Students participate in a laboratory cycle within the CBM module, engaging in multiple experiments on a weekly basis, including Shaft Alignment, which provides meaningful, industry-relevant experience in an engineering environment. During the laboratory sessions, multiple pairs of students complete the experiment simultaneously on multiple custom engineering rigs. The Shaft Alignment procedure, although very relevant to industry needs, is also complex and time consuming, with students often struggling to complete the task within the designated laboratory time. AR technology has …
