Emergency Diesel-Electric Generator Set Maintenance And Test Periodicity, Stephen John Fehr
Emergency Diesel-Electric Generator Set Maintenance And Test Periodicity, Stephen John Fehr
Engineering Management & Systems Engineering Theses & Dissertations
Manufacturer and industry recommendations vary considerably for maintenance and tests of emergency diesel-electric generator sets in emergency standby duty. There is little consistency among generator sets of similar technology, and manufacturers and their representatives often provide contradictory guidance. As a result, periodicity of emergency diesel-electric generator set maintenance and tests varies considerably in practice. Utilizing the framework proposed and tested by Fehr (2014), this research developed a parametric regression survival model of the reliability of modern diesel-electric generator sets in emergency standby duty as a function of maintenance, age, and cumulative run hours. A survival regression technique leveraging Cox’s (1972) …
Methods For Analyzing Attribute-Level Best-Worst Discrete Choice Experiments, Amanda Faye Working
Methods For Analyzing Attribute-Level Best-Worst Discrete Choice Experiments, Amanda Faye Working
Mathematics & Statistics Theses & Dissertations
Discrete choice experiments (DCEs) have applications in many areas such as social sciences, economics, transportation research, health systems, and clinical decisions to mention a few. Usually discrete choice models (DCMs) focus on predicting the product choice; however, these models do not provide information about what attributes of the products are impacting consumers’ choices the most. Today, it is common to record the best and worst features of a product (or profile), also called attribute levels, and the goal is to investigate and build models for estimation of attribute and attribute-level impacts on consumer behavior. Attribute-level best-worst DCEs provide information into …
Healthcare Outcomes And Resource Utilization Associated With Neonatal Hypoglycemia: Analysis Of Data From The Hcup Kid’S Inpatient Database, Brook T. Alemu
Healthcare Outcomes And Resource Utilization Associated With Neonatal Hypoglycemia: Analysis Of Data From The Hcup Kid’S Inpatient Database, Brook T. Alemu
Health Services Research Dissertations
Neonatal hypoglycemia is the most common metabolic abnormality in infants and is associated with neurological damage and death. The risk of developing hypoglycemia among infants born from diabetic mothers is even higher. Although much work has been performed addressing issues for treatment and care, research related to neonatal hypoglycemia has been focused on the clinical or individual level risk factors. Contextual risk factors such as hospital characteristics, neighborhood economic status, and regional variations were not considered in earlier studies. Additionally, although healthcare resources utilization of hypoglycemia has been adequately addressed in the adult population, this topic has not been studied …
