Multipolarity and East Asia.
(1982)The East Asian geographic subsystem was chosen as the region to be analyzed because of the author's belief that changes in the East Asian subsystem since 1945 have always preceded changes in the global international system. ... -
A multiscale analysis of factors influencing the distributions of birds in the southern Great Plains.
(1998)I studied the influence of local- and landscape-level habitat factors on breeding-bird communities in a prairie landscape in southwestern Oklahoma, U.S.A. Local habitat characteristics were sampled at study plot transects. ... -
A multiscale analysis of nest-site choice, nest success, and population abundance in the scissor-tailed flycatcher (Tyrannus forficatus).
(2000)I used BBS data and habitat maps to examine associations of landscape structure and composition with the relative mean abundance of the scissor-tailed flycatcher. Routes were scattered over most of the breeding range. ... -
Multiscale analysis of seismic event source parameter resolution and characterization
(2021)Earthquake source parameters such as stress drop help us understand the underlying physics of tectonic stress loading and releasing associated with the occurrence of earthquakes, and the influence of human activity on the ... -
Multiscale Dispersion Characterization and Breakdown of Nanoclay Clusters during Molding
(2005)Thermo-mechanical properties of polymers can be significantly altered by the addition of nano-scale particulates such as carbon nanotubes and nanofibers. Among the nano-scale particulates, inclusion of nanoclay is proven ... -
A Multiscale Investigation of the 26–27 April 2011 Tornado Outbreak
(2021-12)One of the most prolific tornado outbreaks ever documented occurred on 26–27 April 2011 and comprised three successive episodes of tornadic convection that primarily impacted the southeastern United States, including two ... -
Multiscale modeling and simulation: Incorporation of mesoplasticity between atomistic and continuum
(2007-08)Scope and Method of Study: In the framework of multiscale modeling, two modeling techniques at the meso/micro scale, namely, mesoplasticity and discrete dislocation are employed to study the mechanical behavior of single ... -
Multiscale modeling of fractured reservoir stimulation and induced seismicity
(2020-12-18)Natural fractures and fracture networks characteristics significantly influence the success of reservoir stimulations. Subsurface and surface investigations consider various geophysical techniques to probe and measure ... -
Multiscale Modeling of Hybrid Structural Composites Enhanced by Aligned Zinc Oxide Nanowires
(2022-05)Interfacial properties between fibers and matrix can significantly impact the overall performance of the composite structures. One pioneering approach to enhancing the interfacial properties is growing nanostructures on ... -
Multiscale Modeling of Nanoparticles Transport, Aggregation, and In Situ Gelation in Porous Media
(2017)Nanoparticle applications in the petroleum industry have grown recently especially in EOR and well stimulation. Transport of nanoparticles in porous media involves different interaction mechanisms either between nanoparticles ... -
MULTISCALE NATURAL FRACTURE CHARACTERIZATION WORKFLOW FOR UNCONVENTIONAL SHALE, WOODFORD AND BARNETT SHALES AS EXAMPLES
(2019-12-13)This research presents an integrated methodology and workflow to characterize, interpret and predict natural fracture occurrence in different scales for unconventional shales using the Devonian-Mississippian Woodford and ... -
MULTISCALE RESPONSES TO PERTURBATION IN THE CONTEXT OF A HIGHLY CONTAMINATED FIELD SITE
(2024-05-10)Microbes and microbial communities are ubiquitous in the environment and responsible for the cycling of carbon, sulfur, nitrogen, phosphorous, and more, while also being subject to variable conditions ranging from seasonal ... -
Multiscale Simulation from Atomistic to Continuum -- Coupling Molecular Dynamics (MD) with Material Point Method (MPM)
(Oklahoma State University, 2004-12-01)Failure in single crystals and polycrystalline materials usually involve processes such as dislocation, cleavage, macrocrack initiation and growth as well as coalescence until final fracture. Multiscale modeling is necessary ... -
Multiscale simulation using the generalized interpolation material point method, discrete dislocations and molecular dynamics
(2006-05)Scope and Method of Study: A multiscale simulation scheme that spans the atomistic scale to the continuum has been developed for materials simulations in this study. At the continuum scale, the generalized interpolation ... -
MULTISCALE SIMULATIONS OF HEAT TRANSFER IN NANOCOMPOSITES
(2012)The field of nanotechnology has been expanded by the discovery of fullerenes and carbon nanotubes (CNTs) in the 20th century. Geim and Novoselov won the Nobel prize in 2010 for their work on graphene sheets (GSs). Those ... -
MULTISCALE SPATIOTEMPORAL ANALYSES OF SEISMICITY AND WASTEWATER INJECTION IN OKLAHOMA
(2017-05)The increase in seismicity in Oklahoma since 2009 has been primarily attributed to wastewater disposal, however, the extent and nature of the relationship is not clear. On the state level, there is no statistically significant ... -
Multiscale study of effects of brine type and ionic strength on the wettability alteration of naphthenic-acid-adsorbed calcite and calcite-coated glass surfaces
