Component specific modeling
The objective was to develop and verify a series of interdisciplinary modeling and analysis techniques specialized to address hot section components. These techniques incorporate data as well as theoretical methods from many diverse areas, including cycle and performance analysis, heat transfer analysis, linear and nonlinear stress analysis, and mission analysis
Component specific modeling
The objective is to develop and verify a series of interdisciplinary modeling and analysis techniques that have been specialized to address three specific hot section components. These techniques will incorporate data as well as theoretical methods from many diverse areas including cycle and performance analysis, heat transfer analysis, linear and nonlinear stress analysis, and mission analysis. The new methods developed will be integrated to provide an accurate, efficient, and unified approach to analyzing combustor burner liners, hollow air-cooled turbine blades, and air-colled turbine vanes. For these components, the methods developed will predict temperature, deformation, stress, and strain histories throughout a complete flight mission

Practice VS. Evidence: Predicting Insertion Length and Verifying Placement of Feeding Tubes in Neonates
The placement of nasogastric (NG) and orogastric (OG) feeding tubes is one of the most common procedures performed in the Neonatal Intensive Care Unit (NICU). According to the literature, as many as 44% of feeding tubes are placed in the incorrect location in children (Parker, Withers, & Talaga, 2018). The purpose of this process evaluation project was to analyze the current processes and human factors in predicting insertion length and verifying placement of feeding tubes in neonates. The goal was to use the data obtained to compare current practices to current evidence. If warranted, the ultimate goal was for the data obtained to lead to a future practice change. The setting was Kentucky Children’s Hospital NICU and the target population was registered nurses (RNs) in the NICU. Inclusion criterion was RNs employed by University of Kentucky Health Care that work in the NICU. RNs working all shifts were included, as well as full and part time nurses. Exclusion criterion was RNs still in orientation at the time of the project. Approval was obtained from the University of Louisville Institution Review Board and the University of Kentucky Nursing Research Committee. Data were collected via a survey distributed to the NICU nursing listserv using SurveyMonkeyTM. The data collected showed that non-evidence based practice continued to be used for predicting insertion length and verifying placement of feeding tubes. Findings from the project were presented to the nursing staff through a PowerPointTM report format
Component-specific modeling
Accomplishments are described for a 3 year program to develop methodology for component-specific modeling of aircraft hot section components (turbine blades, turbine vanes, and burner liners). These accomplishments include: (1) engine thermodynamic and mission models, (2) geometry model generators, (3) remeshing, (4) specialty three-dimensional inelastic structural analysis, (5) computationally efficient solvers, (6) adaptive solution strategies, (7) engine performance parameters/component response variables decomposition and synthesis, (8) integrated software architecture and development, and (9) validation cases for software developed
