A Triple-Porosity Model for Fractured Horizontal Wells
(2010-10-12)
Fractured reservoirs have been traditionally idealized using dual-porosity models.
In these models, all matrix and fractures systems have identical properties. However, it
is not uncommon for naturally fractured reservoirs ...
Development of Quality Assurance Methods for Performance-Based Maintenance Contracts for Roadway Assets
(2011-02-22)
Performance-based Maintenance Contracts (PBMCs) are increasingly being used for
roadway maintenance as an alternative to method-based specifications. However, this
technique is still relatively new and several issues ...
Phylogenetic Toric Varieties on Graphs
(2010-10-12)
We define the phylogenetic model of a trivalent graph as a generalization of a
binary symmetric model of a trivalent phylogenetic tree. If the underlining graph is a
tree, the model has a parametrization that can be expressed ...
The Effect of Ashe Juniper Removal on Groundwater Recharge in the Edwards Aquifer
(2011-02-22)
Understanding groundwater recharge rates has direct relevance for management of the Edwards Aquifer, which serves as the main source of fresh water for the city of San Antonio and surrounding communities. As population ...
The Mystery of the Chaetognatha: A Molecular Phylogenetic Approach Using Pelagic Chaetognath Species on Pelican Island, Galveston, Texas
(2011-02-22)
The phylum Chaetognatha is a mysterious group of organisms that has eluded
scientists for more than a century because of their unique morphology and
developmental characteristics, i.e. protostome (mouth develops from ...
Characterization of Product Quality Attributes and Thermal Properties of Potato Chips during Vacuum Frying
(2010-10-12)
Vacuum frying is an alternative processing method for producing high quality
snacks with the advantages of lower processing temperature, enhanced organoleptic
quality, and reduced acrylamide content. Vacuum frying (1.33 ...
Determination of soil properties for sandy soils and road base at Riverside Campus using laboratory testing and numerical simulation
(2010-07-14)
This study evaluated the soil properties of clean sand, a silty sand, and a road base that are extensively used as a backfill for full-scale testing at Riverside Campus at Texas A&M University. The three soils were collected ...
Advancement of Erosion Testing, Modeling, and Design of Concrete Pavement Subbase Layers
(2010-10-12)
Concrete pavement systems have great capacity to provide long service lives; however, if
the subbase layer is improperly designed or mismanaged, service life would be
diminished significantly since the subbase layer performs ...
Radioactive Flow Characterization for Real-Time Detection Systems in UREX+ Nuclear Fuel Reprocessing
(2011-02-22)
The reprocessing of used nuclear fuel requires the dissolution and separation of
numerous radioisotopes that are present as fission products in the fuel. The leading
technology option in the U.S. for reprocessing is a ...
Spent Nuclear Fuel Self-Induced XRF to Predict Pu to U Content
(2010-10-12)
The quantification of plutonium (Pu) in spent nuclear fuel is an increasingly important safeguards issue. There exists an estimated worldwide 980 metric tons of Pu in the nuclear fuel cycle and the majority is in spent ...
