Equipment replacement prioritization measures : simulation and testing for a vehicle fleet

Creator:: Kriett, Phillip Oliver
Abstract:: Oregon Department of Transportation (ODOT) Fleet Services manages a fleet that in 2008 included approximately 5,000 pieces of active equipment worth $340–$390 million. Every biennium, a fixed budget is available to replace a certain amount of this equipment. This research evaluated various measures for establishing equipment replacement priorities. A model...

Impact of asset usage preferences on parallel replacement decisions

Creator:: Wagner, Tristan John
Abstract:: 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...

Evaluating the effectiveness of spare parts replenishment methods for warranty service satisfaction

Creator:: Bluett, Andrew H.
Abstract:: After a mobile communication device (MCD), such as a smartphone or tablet, has been sold to the public, the customer may find that there is a defect. Each MCD is sold with a warranty that covers the repair of manufacturing defects and is supported by the MCD manufacturer. A third...

Automated manipulation of zebrafish embryos for high-throughput toxicology screening of nanomaterials

Creator:: Mandrell, David
Abstract:: 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...

Modeling and optimization of radio frequency identification networks for inventory management

Creator:: Suriya, Atipong
Abstract:: Stock loss and out-of-stocks are outcomes of poorly designed inventory management systems and can lead to significant revenue losses. Inventory management systems (IMS) based on radio frequency identification (RFID) have the potential to minimize these losses if they are properly designed and deployed. However, the placement of RFID readers to...

Impact of RFID Technology on Replenishment Decisions for Multi-Echelon Supply Chains

Creator:: Cavazos Sanchez, Myrna Leticia
Abstract:: Radio frequency identification (RFID) has long been regarded as an automated data collection technology that promises solutions to inefficiencies found in supply chains such as “just-in-case” inventory stock, inventory obsolescence, stockouts, and theft. However, the disappointingly slow return on RFID investment has forced companies to examine and redefine RFID initiatives....

Materials and process design for powder injection molding of silicon nitride for the fabrication of engine components

Creator:: Lenz, Juergen H. (Juergen Herbert)
Abstract:: A new material system was developed for fabricating the combustion engine of an unmanned aerial vehicle. The material system consisted of a mixture of nanoscale and microscale particles of silicon nitride. Magnesia and yttria were used as sintering additives. The powders were mixed with a paraﬃn binder system. The binder-powder...

Potential of Genetic Algorithms for Design of Liquid Cooled Heat Sinks Fabricated Using Additive Manufacturing

Creator:: Dokken, Connor B.
Abstract:: The advancement of new manufacturing techniques such as additive manufacturing enable significantly greater freedom of design compared to conventional techniques. Of significant interest is what improvements could be made in the design of cold plates and heat sinks for electronics cooling. Greater design freedom could potentially enable new designs that...

Sources of flow maldistribution in microreactor-assisted synthesis of ceria nanoparticles

Creator:: Tseng, Chih-Heng
Abstract:: Recent efforts show that microchannel technologies have much to offer the field of nanomanufacturing: the structuring of matter on the order of one billionth of a meter. During the synthesis of nanomaterials, microchannel reactors take advantage of large surface-to-volume ratios to accelerate heat and mass transport. This accelerated transport allows...

Analysis of the Effects of Combustion Products on Forced Ignition and Turbulent Flame Propagation

Creator:: Bonebrake, Jonathan M.
Abstract:: Practical combustion devices frequently rely upon forced ignition of turbulent fuel/oxidizer mixtures that also contain the product species of combustion. Examples of this include engines that use exhaust gas recirculation (EGR), inter-turbine burners in aircraft engines, and other systems the utilize staged combustion. In this work, the effects of major...
