Modeling hop kilning with respect to energy consumption and drying kinetics

Creator:: Thomas, Matthew W.
Abstract:: Currently, little work has been performed studying energy consumption in hop kilning. This thesis explores drying with an alternative drying schedule that extends the initially elevated drying temperature currently used by growers and examines its impact on drying time and energy use. Extending the time of the initially elevated drying...

The Effect of Process Improvement Practices on Kuwaiti Manufacturing Companies

Creator:: Khajah, Abdullah Saheb
Abstract:: Awareness and implementation of process improvement strategies, like Six Sigma, Total Quality Management, and Lean Management have increased since the 1980s. In more recent history, lean management thinking has shown its significance in the manufacturing world. Kuwait, being a country in which its whole dependence is on revenues of oil...

Influences of Replacing Cr with Mo in Fe25Co25Ni25Cr25-XMoX High Entropy Alloy Series on the Microstructure and Mechanical Properties

Creator:: Xu, Yifan
Abstract:: Fe25Co25Ni25Cr25-XMoX High Entropy Alloys were fabricated in mini arc-melter and then cast into 4mm diameter cylinders by injection casting technique and 1cm diameter cylinders by water quenching technique. Heat transfer modeling during solidification of FeCoNiCr HEA was simulated. Combining X-Ray Diffraction, Optical Microscopy, Scanning Electron Microscope, Energy Dispersive X-ray analysis,...

Time-Dependent Crack Growth Mechanisms in Alloy 617 at 800°C in Air

Creator:: Addison, Dylan, A.
Abstract:: Time-dependent crack growth mechanisms in Alloy 617 at 800°C in air were studied using compact tension samples machined in the L-T direction, cracked at temperature using an induction furnace and servo-hydraulic load frame. The application of different loading waveforms, including triangular, hold time, and sustained loading, were studied with relation...

An Application of Visual Management to Reduce In-house Material Handling Wastes in SMEs with High Product Variety and Low Volume

Creator:: Kopriva, Cody
Abstract:: Small and medium-sized enterprises that are characterized by high-mix, low-volume, and highly variable production operations often have unstructured material movement processes that are prone to material handling wastes. These sub-optimal material handling systems are oftentimes a result of small and medium-sized enterprise's limited resources. Current tools to assist organizations in...

Numerical design of a high-flux microchannel solar receiver

Creator:: Rymal, Charles
Abstract:: This thesis discusses the design of several microchannel solar receiver devices for use in CSP (concentrated solar power) using CFD (computational fluid dynamics) simulations. The goal is to demonstrate that, by taking advantage of the higher heat transfer coefficienct of microchannels, solar receivers can achieve higher efficiency than current receiver...

A wireless sensor network approach for estimating individual task time

Creator:: Atichat, Tanawat
Abstract:: Most existing methods for generating individual task time estimates in production systems where jobs move through various manually operated workstations remain tedious and time consuming. For existing systems, average task times may vary considerably from prior estimates causing system inefficiencies, poor scheduling and poor planning decisions. Accurate and up-to-date estimates...

The impact of shared ownership on virtual team effectiveness

Creator:: Bonnono, Mark A.
Abstract:: This research studied the role of shared ownership on virtual team effectiveness, using student teams enrolled in engineering management coursework at Oregon State University and Virginia Polytechnic Institute. After a thorough review of the literature, the concept of shared ownership was developed. This concept was operationalized as the extent to...

Failure analysis of pre-notched composite laminated plates under four-point bending conditions

Creator:: Arias Gonzales, Sergio
Abstract:: Ever since composite laminate technology was introduced into the aerospace and automotive industry, there has been a need to fully understand the damage progression experienced by composite laminated plates in the presence of a notch. While numerous research studies have been conducted on this matter when subjected to in-plane loads,...

Investigation of the hospital consumer assessment of healthcare providers and systems survey and its impact on hospital performance

Creator:: Worley, June M.
Abstract:: In 2007, the Centers for Medicare and Medicaid Services began requiring many hospitals in the United States to randomly survey patients who had stayed at least one night in the hospital. The Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) survey provides hospitals with valuable performance measurement data built...
