Many Departments of Transportation (DOTs) have done construction and maintenance work at night in order to minimize the disruption of daytime traffic, but nighttime operations produce a new set of concerns such as safety, public relations, productivity, and work quality. In addition, decision-making for using nighttime operations has been subjective...
The study hypotheses, based on sociobiology, were that the more committed and positive the parental relationship, the greater the likelihood of breastfeeding and of later weaning. Data from the Fragile Families and Child Wellbeing Study was used; sample size was 3635, and over half were African- 2merican. In a logistic...
The use of mobile bar code scanners is expanding to markets beyond popular manufacturing uses, such as healthcare, environmental testing and professional services. The successful interaction of users with mobile bar code scanners is of great importance from a business and technology perspective as well as from the user standpoint....
Hydrogels have been proposed as candidates for nucleus pulposus replacement due to
their similarity in mechanical behavior to the native tissue when subjected to transient or
static loading; however, given the viscoelastic nature of soft biological tissues, the lack of
dynamic testing is a significant inadequacy in the studies performed...
Due to growing global competition, especially in the last decade, the United States wood and wood-based industries have suffered significant market share losses. The wood industry in Germany is facing similar challenges. To stay competitive in an increasingly global marketplace, many wood manufacturers are adopting new management/manufacturing approaches. Lean manufacturing...
The increase of diesel fuels and natural gas has increased the energy cost of the mint
oil extraction industry in the Willamette Valley. In this study the energy evaluation of
a distillation facility in Oregon is considered. Solvent free microwave extraction of
peppermint oil is introduced as a new technique...
This research proposes a Human Fallibility Identification and Remediation Methodology (HFIRM) that supports the systematic identification and remediation of potential human errors. The objective of this research was to develop and test a prototype framework that supports the practical application of human factors knowledge to the analysis and design of...
Modern complex mechanical systems have evolved to a point of incredible complexity. Many now operate with significant assistance from automated response functions, and some operate without human operators at all. These increasingly complex systems have also become more expensive and more ambitions in mission, bringing about higher risk to both...
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...
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...
