Regression and neural network modeling of resilient modulus based on routine soil properties and stress states.
(2006)
The laboratory results from the fourteen sites from fourteen counties were used to develop the relationships or models.
Neural network and analytical modeling of slope stability.
(2002)
A semi-analytical method is developed for analysis of slope stability involving cohesive and non-cohesive soils. For sandy slopes, a planar slip surface is employed. For clayey slopes, circular slip surfaces are employed ...
Investigating the need for and effect of air entrainment in high performance concrete.
(2002)
The use of high performance concrete (HPC) in exterior structures has increased in recent years. Its increased strength and durability make HPC very appealing to the prestressed concrete industry, particularly in bridge ...
Durability of cementitiously stabilized aggregate bases for pavement application.
(2005)
Cementitious stabilization has been extensively used to improve the performance of pavement materials. In the past, emphasis has been placed on observing the macromanifestation of stabilized pavement materials, but to the ...
A framework-based finite element approach for solving large deformation problems in multi-phase porous media.
(2005)
The performance of the uniform gradient element formulation is studied by simulating settlement of a footing and dynamic behavior of a saturated clay embankment and a level ground. Significant hourglassing is seen for the ...
A practicing engineer's perspective on nonlinear finite element analysis techniques for reinforced concrete structures.
(2004)
The research demonstrates the continued progress in finite element analysis of reinforced concrete structures. Increasingly, structural engineers will use this method in their designs, and in research into materials and systems.
Impact of physiological state and macro-nutrient ratio on microbial surface thermodynamics and transport.
(2002)
As both deposition and retardation occur during bacterial transport, the deposition coefficient and retardation factor have been widely used individually in describing the transport of bacteria through porous media. Rijnaarts ...
Anisotropic poromechanics of the wellbore coupled with thermal and chemical gradients.
(2002)
A generalized anisotropic porothermoelastic formulation incorporating fully coupled thermo-hydro-mechanical response of saturated porous media is developed. Governing equations are tailored for transversely isotropic media ...
Development of a Web-based infrastructure management system for Oklahoma's general aviation airports, and, Exploring the use of spectral analysis of surface waves and impulse response for pavement health monitoring.
(2007)
The transportation infrastructure of the United States consumes over 17% of its Gross National product annually and is currently valued at $1.75 trillion. With the interstate system now 50 years old, the emphasis of the ...
Algorithmic improvements and analyses of the generalized wave continuity equation based model, ADCIRC.
(2005)
Second, nearly all GWC-based models utilize a velocity-based, non-conservative momentum equation (NCM) to obtain the depth-averaged velocity profile. It has been hypothesized that the conservative momentum equation (CM) ...
