Robust Cross-Dock Location Model Accounting For Demand Uncertainty, Stephanie Spangler

Graduate Theses, Dissertations, and Problem Reports (ETD)

The objective of this thesis was to develop optimization models to locate cross-docks in supply chain networks. Cross-docks are a type of intermediate facility which aid in the consolidation of shipments, in which the goods spend little or no time in storage. Instead, the goods are quickly and efficiently moved from the inbound trucks to the outbound docks. Two deterministic facility location models were developed. One followed the p-median facility problem type, where only p facilities were opened in order to minimize total network costs. In the second model, as many cross-docks as necessary were opened and facility location costs …

Hydrologic Response Of Alternative Valley Fill Reclamation Designs, Michael W. Snyder

Graduate Theses, Dissertations, and Problem Reports (ETD)

Mountaintop mining (MTM) is a widely practiced surface mining technique in Central Appalachian Conventional reclamation (Approximate Original Contour), involves the construction of valley fills of headwater systems. Recent research suggests that current MTM reclamation techniques increase stormflow response of the affected watersheds when compared to the original, undisturbed conditions. One method that has shown success in reclaiming surface mine sites in semi-arid regions of the western U.S. is geomorphic landform design. Geomorphic reclamation is based upon creating landforms that resemble the mature surrounding watersheds in both topography and hydrologic response. The objective of this research was to predict the hydrologic …

Using Bio-Chars As Potential Catalysts For Upgrading Wood Pyrolysis Vapors, Wenjia Jin

Graduate Theses, Dissertations, and Problem Reports (ETD)

Pyrolysis is a promising thermochemical conversion method to process lignocellulosic biomass to produce bio-oil that can be further refined into chemicals and fuels compatible with current petrochemical fuels. However, bio-oils are highly reactive and unstable and therefore must be refined immediately, thereby reducing process sustainability. Catalytic modifications of pyrolysis vapors have been researched to improve bio-oil stability. However, using traditional highly active petroleum refining cracking catalysts for catalytic pyrolysis has shown some negative results, for example, increasing bio-oil moisture content and reducing its calorific value. Therefore, this project aims at understanding decomposition behavior of wood components, its chemical constituent polymers …

In order to address the increasing trend of firewood use and prevent further …

Response Of Continuous Steel I-Girder Bridges Subject To Temperature Variation, Christopher L. Beckett

Graduate Theses, Dissertations, and Problem Reports (ETD)

Thermal deformation of the superstructure in continuous slab-on-girder bridges must be freely permitted to avoid potential adverse behavior due to the development of thermal forces. The use of fixed and guided bearings can introduce a significant amount of restraint against thermal deformation that, if not accommodated by the supporting piers, will lead to thermal stresses throughout the structure, most notably in substructure elements (piercaps, bearing assemblies, bearing anchor bolts). The potential effects of restrained thermal deformation in steel I-girder bridges have not been clearly demonstrated. Additionally, the method provided in AASHTO specifications for orienting guided expansion bearings on horizontally curved …

The Political Economy Of U.S. Public Pension Plans And Their Unfunded Liabilities, Dashle Gunn Kelley

Graduate Theses, Dissertations, and Problem Reports (ETD)

Chapter 1 applies a public choice approach to the problem of unfunded pension liabilities and adopts the methodology of Congleton and Shughart (1990) to model underfunding of state-level public pension plans using the median voter theorem, along with the theory of "capture" by special interest groups, and a combined model of the two. With panel data from 2001 to 2009, the paper finds that the combined model provides the strongest explanation for the current levels of unfunded liabilities; hence, both median voter preferences and special interest group influence are affecting political outcomes. The special interest group model slightly outperforms the …

Review Of Imaginary Citizens: Child Readers And The Limits Of American Independence, 1640–1868 By Courtney Weikle-Mills, James Marten

History Faculty Research and Publications

No children appear in Imaginary Citizens until chapter 4, and then just barely; their presence would have made this a very different book. Yet they remain central to Courtney Weikle-Mills's argument that during the 250 years after Europeans came to the New World, children and childhood provided real and metaphorical meanings to freedom and citizenship and reflected the ways democratic values could actually be shaped by words.

Effects Of Trauma Induced Stress On Attention, Executive Functioning, Processing Speed, And Resilience In Urban Children, Antoinette Welsh

Seton Hall University Dissertations and Theses (ETDs)

Brain development, and particularly structures involved in executive functioning, occurs at different rates in children, leading to differential performance in school. Due to neuroanatomical changes secondary to the stress response, children who have experienced stress as a result of poverty and traumatic events may be at increased risk for cognitive difficulties, including attention, executive functioning, and processing speed (Blair, Granger, & Razza, 2005; DeBellis, Hooper, & Sapia, 2005). Prevalence rates among urban children suggest that 70-100% have been exposed to trauma (Dempsey, Overstreet, & Moely, 2000; Macy, Baryry, & Noam, 2003). Some of these children develop posttraumatic stress disorder and …

Caveolins And Njks Influence Brain Endothelial Permeability After Juvenile Tbi, David Olufemi Ajao

Loma Linda University Electronic Theses, Dissertations & Projects

Disruption of blood-brain barrier (BBB) is a key secondary event that exacerbates brain damage following traumatic brain injury (TBI). BBB disruption is particularly damaging to the developing brain – which is highly vulnerable to various stress stimuli, resulting in increased brain swelling, disrupted cerebral blood flow (CBF) autoregulation, long-term disabilities and death following TBI in young demographic. Unsurprisingly, BBB disruption and the resultant cerebral edema have emerged as therapeutic targets in juvenile TBI. It is therefore important to understand the molecular players and mechanisms involved in TBI-induced BBB disruption in the juvenile brain. To this end, the endothelial caveolins and …
