Research On Vibration-Based Early Diagnostic System For Excavator Motor Bearing Using 1-D Cnn, Dorjsuren Yandagsuren, Tatsuki Kurauchi, Hisatoshi Toriya, Hajime Ikeda, Tsuyoshi Adachi, Youhei Kawamura

Journal of Sustainable Mining

In mining, super-large machines such as rope excavators are used to perform the main mining operations. A rope excavator is equipped with motors that drive mechanisms. Motors are easily damaged as a result of harsh mining conditions. Bearings are important parts in a motor; bearing failure accounts for approximately half of all motor failures. Failure reduces work efficiency and increases maintenance costs. In practice, reactive, preventive, and predictive maintenance are used to minimize failures. Predictive maintenance can prevent failures and is more effective than other maintenance. For effective predictive maintenance, a good diagnosis is required to accurately determine motor-bearing health. …

Journal of Sustainable Mining

Accurate information on Young’s modulus (E) is required for simulating rock deformation in mines; on the other hand, it is very cumbersome to obtain in the laboratory and collecting drilled cores in sufficient amounts, especially in the case of soft rocks, is quite impossible. Empirical equations were deducted for E from easily determinable rock properties, and the final model was selected through different statistical strength parameter tests. The generalization of the equation was verified through the normal distribution tests of residues of the equation. R2 came to be 0.609 and was validated using an artificial neural network with an improved …

Spatial Validation Of Agent-Based Models, Kristoffer Wikstrom, Hal T. Nelson 2022 Claremont Graduate University

Spatial Validation Of Agent-Based Models, Kristoffer Wikstrom, Hal T. Nelson

Public Administration Faculty Publications and Presentations

This paper adapts an existing techno–social agent-based model (ABM) in order to develop a new framework for spatially validating ABMs. The ABM simulates citizen opposition to locally unwanted land uses, using historical data from an energy infrastructure siting process in Southern California. Spatial theory, as well as the model’s design, suggest that adequate validation requires multiple tests rather than relying solely on a single test-statistic. A pattern-oriented modeling approach was employed that first mapped real and simulated citizen comments across the US Census tract. The suite of spatial tests included Global Moran’s I, complemented with bivariate correlations, as well as …

Closing The Loop: An Examination Of Consumer Attitudes And Motivation For Sustainable Behaviors, Jennifer D. Henderson 2022 University of South Alabama

Closing The Loop: An Examination Of Consumer Attitudes And Motivation For Sustainable Behaviors, Jennifer D. Henderson

Theses and Dissertations

Smartphones and related electronic devices are a recently growing area of ethical, environmental, and social responsibility concern. Specifically, these products generate large quantities of electronic waste (e-waste) and are increasingly produced under questionable working conditions. These social and environmental impacts can potentially be mitigated through the adoption of sustainable consumer behaviors, such as e-waste recycling and purchasing sustainably- produced devices. However, although we are years into the modern sustainability movement, there still exists an attitude-behaviors gap where many consumers report that they are concerned about environmental and social responsibility issues, but they fail to translate these concerns into consumption behaviors. …


How Low Can You Go? Expanding Oyster Tidal Niche With Predator Induction, Carter Lin 2022 University of South Alabama

How Low Can You Go? Expanding Oyster Tidal Niche With Predator Induction, Carter Lin

Theses and Dissertations

An oyster’s realized niche is constrained by different stressors based on tidal elevation, such as desiccation or benthic predators. These factors constrain survival and set the boundary for their realized niche. Eastern oysters (Crassostrea virginica) also harden their shells in response to predation risk which reduces their mortality. We performed an empirical study to investigate if this defense mechanism could be manipulated to expand their realized niche. We raised oysters in the presence of blue crab predators (Callinectes sapidus) or in controls sans predators, then monitored their survival at different tidal elevations. Oyster survival was significantly higher in the highest …
