Transient liquid-phase diffusion brazing is used in precision, hermetic joining applications as a replacement for diffusion bonding to reduce cycle times, reduce bonding pressure and improve yields. Studies showed that the interlayer used in diffusion brazing can be detrimental due to the use of melting point depressants (MPDs). The goal...
Data from a state department of transportation fleet shows that the usage of a typical asset decreases as it ages. One possible explanation for decreasing asset usage with age is operator preference for using the newest available asset. In this research the long-term cost and replacement implications of such a...
Distractions and interruptions are common occurrences in an operating room (OR), but little is known about their effects on surgical task performance. Based on human factors research, it was hypothesized that realistic distractions and interruptions in an OR would adversely impact surgical task performance. Because of the concern of patient...
Continuous Improvement (CI) is an integral part of hospital administration. This study examined the relationship between five CI variables against six hospital criterion measures of, wait times to prepare a room, patient costs per day, waiting time for lab results, reportable errors, patient satisfaction, and employee satisfaction. The research was...
The OSU Society of Automotive Engineers (SAE) is a nonprofit, student-run organization dedicated to enhancing its members‟ engineering, leadership, communication, and teamwork skills. The OSU Formula SAE team objective is to design, build, and race an autocross style car that competes at annual events worldwide. The purpose of the proposed...
The Society of Automotive Engineers organizes the Formula SAE competitions annually for universities internationally to compete in a series of events. Teams compete in several dynamic tests for the vehicle’s handling, performance, and fuel economy, as well as static events that judge the team’s assumptions for cost, design, and business...
Qualitative data analysis (QDA) is a time consuming and, potentially unreliable research activity. In qualitative research, a number of tasks must be repeated for every new research case, even if each case is closely related or is in the same area of study.
Existing QDA applications provide users with a...
Work engagement is demonstrated when employees are involved with, committed to,
enthusiastic, and passionate about their work. The goal of this study was to summarize
relevant information on work engagement, produce a working coding system to identify
evidence of work engagement, and discuss the implications of work engagement on an...
Microchannel arrays are being developed across a wide spectrum of microfluidic applications including blood processing, fuel cells and thermal management among many others. Typical arrays are based on a flat laminated architecture produced in a vacuum hot press (VHP) through solid-state diffusion bonding. Due to the cylindrical nature of certain...
The field of nanotechnology has been rapidly developing new materials. These materials have become incorporated into consumer products and the environment after only minimal assessment of their effects on human health or the environment. The toxicity of these new nanomaterials remains unknown due to the unpredictable nature of the core...
