Anisotropic elastic materials capable of a three-dimensional deformation (static or dynamic) with only one displacement component and uncoupling of all three displacement components.
(Elsevier, 2012-01)It is shown that there are anisotropic elastic materials that are capable of a nonuniform three‐dimensional deformation with only one displacement component. For wave propagation the equation of motion can be cast in the ... -
Assessing the impacts of state-supported rail services on local population and employment: A California case study
(Elsevier, 2018-04-01)The State of California has been financially supporting Amtrak intercity passenger rail services since 1976. This paper studies the impacts of this support on local population and employment at both county and city levels. ... -
Behavior of ASTM A325 bolts under simulated fire conditions: Experimental investigation
(Emerald Group Publishing Ltd., 2017)Purpose - Heavy hex structural bolts have been used in a wide range of steel structures for many years. However, these structures remain susceptible to fire damage. Conducting fire experiments on full-scale steel structures ... -
Behavior of skewed extended shear tab connections part I: Connection to supporting web
(Elsevier, 2017-01)The objective of this study is to investigate the behavior of skewed extended shear tab connections in which plate (shear tab) is welded to supporting member webs (flexible supports). To achieve the study goals, Finite ... -
Bistability, Autowaves and Dissipative Structures in Semiconductor Fibers with Anomalous Resistivity Properties
(Taylor & Francis, 2012-01)This work provides a discussion of bistability conditions, switching autowaves properties and emergence of dissipative structures in semiconducting fibers with anomalous positive dependence of electrical resistivity on ... -
Capacity allocation in vertically integrated rail systems: A bargaining approach
(Elsevier, 2018-01)This paper presents a game-theoretic bargaining approach to allocating rail line capacity in vertically integrated systems. A passenger rail agency negotiates with the host freight railroad to determine train schedules and ... -
Complexity in future cities: the rise of networked infrastructure
(Taylor & Francis, 2016-04-06)How will urban infrastructure systems (UIS) be planned in future cities? In the twenty-first century, cities will need to overcome many challenges. They will need to accommodate a growing urban population who aspire for ... -
Cusp singularity-based bistability criterion for geometrically nonlinear structures
(Elsevier, 2016-10-25)This letter introduces a method of analyzing multi-stable truss structures and unit cells of engineered materials using the third order derivative of the formulated system's potential energy function. The method can determine ... -
A domain-reduction approach to bridging-scale simulation of one-dimensional nanostructures
(Springer Verlag, 2011-01)We present a domain-reduction approach for the simulation of one-dimensional nanocrystalline structures. In this approach, the domain of interest is partitioned into coarse and fine scale regions and the coupling between ... -
A dynamic hazard-based system of equations of vehicle ownership with endogenous long-term decision factors incorporating group decision making
(Elsevier, 2011-06-29)The transportation system affects all aspects of our daily lives including relatively long-term decisions on work and home location choice and automobile ownership decisions. The interdependency existing among these three ... -
An efficient methodology for generating synthetic populations with multiple control levels
(National Academy of Science, 2010)This paper details a new methodology for controlling attributes on multiple analysis levels within a population synthesis program. The methodology determines how both household- and personlevel characteristics can jointly ... -
Electrokinetic Remediation of Chlorinated Aromatic and Nitroaromatic Organic Contaminants in Clay Soil
(Mary Ann Liebert, 2011-06)This article presents a bench-scale experimental study performed to investigate the remediation of low permeability clay soil contaminated with pentachlorophenol (PCP), Lindane, and dinitrotoluene (DNT) using electrokinetic ... -
Electrokinetic-Enhanced Transport of Lactate-Modified Nanoscale Iron Particles for Degradation of Dinitrotoluene in Clayey Soils
(Elsevier, 2011-06-07)This study investigated the transport and reactivity of bare nanoscale iron particles (NIP) and lactate modified NIP (LM-NIP) in low permeability clayey soils contaminated with dinitrotoluene (DNT) under applied electric ... -
Embedded discontinuity finite element modeling of fluid flow in fractured porous media
(Springer Verlag, 2013-02)In many geomaterials, particularly rocks and clays, permeability is greatly enhanced by the presence of fractures. Fracture sets create an overall permeability that is anisotropic, enhanced in the directions of the ... -
Emission Control under Private Port Operator Duopoly
(Elsevier, 2018-06-01)Recent trends in regulating maritime vessel emissions have negative effects on the competitiveness of many ports as regulations increase costs for shipping operators calling the ports. This paper develops analytical models ... -
Experimental Study on Chromium Containment by Admixed Soil Liner
(American Society of Civil Engineers, 2012-02)Chrome tanneries generate large quantities of chromium-laden sludge that require proper disposal in engineered landfills to prevent contamination of subsurface soils and groundwater and reduce the risk to public health and ... -
