Inferences On The Power-Law Process With Applications To Repairable Systems, Jularat Chumnaul Dec 2019

Inferences On The Power-Law Process With Applications To Repairable Systems, Jularat Chumnaul

Theses and Dissertations

System testing is very time-consuming and costly, especially for complex high-cost and high-reliability systems. For this reason, the number of failures needed for the developmental phase of system testing should be relatively small in general. To assess the reliability growth of a repairable system, the generalized confidence interval and the modified signed log-likelihood ratio test for the scale parameter of the power-law process are studied concerning incomplete failure data. Specifically, some recorded failure times in the early developmental phase of system testing cannot be observed; this circumstance is essential to establish a warranty period or determine a maintenance phase for …

Bridging The Gaps In Elementary Life Science Lessons, Kaitlin Cook

Honors Program Theses and Projects

The United States is experiencing a rise in science, technology, engineering and mathematics (STEM) careers while facing a shortage of STEM workers. This could partly be due to a decline in the amount of time allowed for science in elementary schools or possibly because many life science lessons in elementary school lack originality and may not stimulate an interest in science. Lack of captivating STEM education prior to college may be contributing to the decline of students graduating with STEM based degrees. My thesis focuses on getting out of the routine of using monotonous life science lesson plans. I identify …

The Dirty Clean Fuel, Sawyer Krivanek Dec 2019

The Dirty Clean Fuel, Sawyer Krivanek

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

Hydraulic fracking began nearly 80 years ago and was initially headlined as a brand new, fuel efficient alternative to coal and oil. Natural gas has been disguised as a clean fuel, when in reality it is just another dirty, polluting, environmentally harmful fossil fuel. The detriments of fracking heavily outweigh the benefits, and it needs to be banned on public and private lands. Natural gas has been viewed as a cleaner alternative to coal and oil, so immediately fossil fuel industries took advantage of that narrative. Consumers, eager for cleaner alternatives, have been tricked into buying into the fracking fad. …

Don’T Give Up On Nuclear Energy, Daniel Gertner Dec 2019

Don’T Give Up On Nuclear Energy, Daniel Gertner

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

The nuclear power plant failures at Three Mile Island and Chernobyl in the late 1970s and 1980s split Americans into two passionate camps. For some, nuclear plants posed serious threats to both environmental and national security, and, for others, nuclear energy remained the most viable path to clean, reliable power in the United States. But following the fervent debates of the late 20th century, the national conversation around nuclear power stagnated. A few ardent advocates and opponents notwithstanding, nuclear power left the public eye. Popular energy debates—especially among young people—now center around flashier topics like the Green New Deal, electric …
