Improved Lubrication Performance of Chainsaw Cutting Systems

Creator:: Sellars, Patrick V.
Abstract:: Chainsaws serve as one of the primary tools used by logging corporations, ranches, and farms for forestry management. Lubricating oil remains one of the heaviest operational expenditures for chainsaws. This largely in part due to chainsaw lubrication being a total loss system in which nearly all lubricating oil applied is...

Proportional integral derivative control of an oil-heated fractal-like branching microchannel desorber

Creator:: Davis, Keith R.
Abstract:: A PID controller was designed to control the performance of an oil-heated fractal-like branching microchannel desorber for use in an ammonia-absorption refrigeration system. Both the amount and concentration of ammonia refrigerant generated at the desorber can be controlled by choosing the rectified circulation ratio as the controlled variable in a...

Aerodynamic undertray design for formula SAE

Creator:: Jensen, Karl
Abstract:: Aerodynamic improvements in automotive racing can have a significant effect on vehicle performance. Recent developments in Formula SAE (Society of Automotive Engineers) have included the design and implementation of aerodynamic devices such as inverted wings and undertrays to improve performance. In this work the literature of undertray technology is presented...

Identifying customer requirements and designing for modularity in developing specialized, low production volume products

Creator:: van Tamelen, Peter G.
Abstract:: Field biologists are in need of more specialized and technical equipment than they are able to produce on their own in order to collect data more efficiently or gather data that is not currently available. This presents a challenge for design engineers because these products are typically highly specialized and...

Technological Improvements in Ligation and Suturing Techniques: A Comparison in the Material Strength of Ligating Clips and Suturing Devices

Creator:: Robertson, Bria L.
Abstract:: Treatment of extrahepatic portosystemic shunts provides many options, including cellophane banding. These cellophane bands are secured with a ligation clip. Weck® offers two forms of these: the stainless steel Hemoclip, and the polymer Hem-o-lok. This in vitro study compares the mechanical strength of these two of types of clips by...

Incremental Forming of Polymers at Room Temperature

Creator:: Davar Panah, Mohammad Ali
Abstract:: Single Point Incremental Forming (SPIF) is a forming process in which a fully clamped sheet is formed by a hemispherical ended tool that moves along a predefined 3D toolpath. The sheet is formed in a series of local deformations to reach its desired shape. Double Sided Incremental Forming (DSIF) includes...

Digital Co-Creation: An Early Stage Product Personalization Methodology to Bridge the User-Designer Void

Creator:: Slama, Timothy J.
Abstract:: Modern product development is a complex combination of multidisciplinary processes ranging from market research to design, engineering analysis, and logistics. The product development process has a significant impact on the success or failure of new product launches. The majority of consumer product launches fail, resulting in significant sunk cost in...

Synthetic Lubricant Performance in Enclosed Gearbox Applications at Extreme Temperature

Creator:: Marr, Carter J.
Abstract:: The goal of this paper is to evaluate how synthetic lubricants perform in an enclosed gearbox application when compared with a proven mineral oil. This is in an effort to improve gearbox efficiency with the desired effect of lower emissions from of improved energy output from power generation. Four liquid...

Microchannel steam-methane reforming under constant and variable surface temperature distributions

Creator:: Eilers, Benn J.
Abstract:: Steam-methane reforming is a well understood industrial process used for generating hydrogen and synthesis gas. The reaction is generally carried out with residence times on the order of one second. By performing this reaction at microscales it is possible to take advantage of increased heat transfer rates and low diffusion...

Swept time-space domain decomposition on GPUs and heterogeneous computing systems

Creator:: Magee, Daniel J.
Abstract:: Modern scientific and engineering problems often require simulations with a level of resolution difficult to achieve in reasonable amounts of time—even in effectively parallelized programs. Therefore, applications that exploit high performance computing (HPC) systems have become invaluable in academia and industry over the past two decades. Addressing the questions that...
