Degradation Modeling And Rul Prediction Using Wiener Process Subject To Multiple Change Points And Unit Heterogeneity, Yuxin Wen, Jianguo Wu, Devashish Das, Tzu-Liang Bill Tseng

Engineering Faculty Articles and Research

Degradation modeling is critical for health condition monitoring and remaining useful life prediction (RUL). The prognostic accuracy highly depends on the capability of modeling the evolution of degradation signals. In many practical applications, however, the degradation signals show multiple phases, where the conventional degradation models are often inadequate. To better characterize the degradation signals of multiple-phase characteristics, we propose a multiple change-point Wiener process as a degradation model. To take into account the between-unit heterogeneity, a fully Bayesian approach is developed where all model parameters are assumed random. At the offline stage, an empirical two-stage process is proposed for model …

Rainwater Harvesting System Scenario Analysis On Runoff Reduction Potential In Surabaya, Indonesia: A Geospatial Analysis For Brantas Hilir Watershed, Putri Sukmahartati

Department of Civil and Environmental Engineering: Dissertations, Theses, and Student Research

Global warming has become an environmental concern over the past several decades and its impact on the water cycle is very crucial to the well-being of the human population. In the hydrological cycle, water evaporates by the heat of the sun and atmosphere, where it is accumulated in the atmosphere via clouds and it then falls as rain. With warmer temperatures, more intensive evaporation and downpours occur. In addition, impervious surfaces are increasing as a result of urban development. Those surfaces cause more water to flow faster into open water bodies, creating more extensive flooding, and additionally reducing water quality. …

A Comparison Of Traditional Education And Project-Based Education In Construction Management, Trey Miller Apr 2018

A Comparison Of Traditional Education And Project-Based Education In Construction Management, Trey Miller

Honors College Theses

Construction is a rapidly moving and constantly changing industry. The skills needed to manage the complex task of running a job site safely, on schedule, and within budget, are unique to the field. Construction Management as an academic field is relatively new discipline. Therefore the field is still rapidly evolving. In many cases, classes are taught by engineering professors, which leads to an engineering-focused education as opposed to a Project Management focused education. Therefore Construction Management students are not receiving the “hands-on” experience early enough in their studies. By structuring classes around an applied project, students will attain a more …

An Investigation Of The Effects Of The Second Pyrolysis On The Chemistry, Morphology, And Performance Of Iron-Nicarbazin Catalysts, Elizabeth B. Weiler

Chemical and Biological Engineering ETDs

Proton exchange membrane fuel cells offer a cost-effective, environmentally friendly, and sustainable alternative to petroleum-based power sources to the transportation sector. However, slow electrochemical reactions at the cathode of these fuel cell prevent the technology from being competitive. Iron-nitrogen-carbon based catalysts have emerged as a viable answer to this problem, yet further progress is needed to improve their performance beyond that of current state-of-the-art platinum-based catalysts, which are economically and geopolitically impractical to be a final solution. Currently, a two-step high temperature pyrolysis method has proven a promising way to synthesize iron-nitrogen-carbon catalysts for optimized performance, but there is a …


Hawai'i Wildlife Fund V. County Of Maui, Lowell J. Chandler Apr 2018

Hawai'i Wildlife Fund V. County Of Maui, Lowell J. Chandler

Public Land & Resources Law Review

In Hawai’i Wildlife Fund v. County of Maui, the Ninth Circuit held that the plain language of the Clean Water Act provides jurisdiction over indirect discharges of pollutants from a point source into groundwater that is shown to be connected to navigable waters. The court found that studies confirmed pollutants entering the Pacific Ocean were fairly traceable to the County of Maui’s sewage disposal wells. In affirming the district court’s ruling, the Ninth Circuit held that Maui County violated the Clean Water Act by discharging pollutants into a navigable water without the required permit. The court also concluded the …

The results showed that it would be possible to generate 28,210,958 Nm3/year of biogas or 154,846 MWh of thermal heat with 110,715 tonnes of CO2 savings in a year. The electricity generation potential and CO2 savings were also calculated. It was possible to conclude that the anaerobic digestion of the wastewater from the brewery and distillery industries stand out as a feasible option to increase the share of renewable energies in Ireland.


Human Behavior Modeling For Residential Energy Consumption, Mesfer Alrizq Apr 2018

Human Behavior Modeling For Residential Energy Consumption, Mesfer Alrizq

Research and Creative Activities Poster Day

Electric utility companies are interested in load profile (electricity consumption) data for expansion planning. Conventional methods of collecting the load profile data, such as surveys and metering, are tedious and time consuming activities. Cumbersome data collection processes also pose barriers. We present an innovative behavior model for generating electricity consumption load profiles. The model, based on fuzzy logic and activity graphs, requires minimum consumer data and can be easily updated to adapt to changes in technology. We demonstrate the accuracy of our model against real world data.


Virtual Reality Power Chair Simulator For Human Operator Modeling And Tremor Filtering, Rick Meyer Apr 2018

Virtual Reality Power Chair Simulator For Human Operator Modeling And Tremor Filtering, Rick Meyer

Faculty Research and Creative Activities Award (FRACAA)

Approximately 180,000 persons who have a need for a powered wheelchair (PWC) suffer from Parkinson's’ hand tremor that makes it difficult, even potentially dangerous, for them to operate it. Persons with hand tremor that attempt to operate a PWC have to try to compensate for their tremor, which may not be realistically possible if the tremor is severe enough. Hand tremor can lead to sudden changes in PWC joystick commands that could result in unsafe PWC movements and collisions resulting in injury and/or property damage. These tremor sufferers are candidates for an assistive PWC. As a step toward assistive PWC, …
