Computer modeling of aerosol diffusion through lung mucosa
(Oklahoma State University, 2020-04-24)Diseases of the lung are some of the most common and deadly in the world, accounting for 4 of the top 10 global causes of death according to the World Health Organization. Existing treatments, if any exist, tend to be ... -
Design of an Axial Flow Bioreactor for Tissue Regeneration
(Oklahoma State University, 2012-05-01)Modeling of bioreactors using Computational Fluid Dynamics (CFD) tools have been adapted for several bioreactor configurations such as flow-through, parallel-flow, and rotary. In this study, modeling was mainly performed ... -
Development and validation of a reduced order fin-and-tube heat exchanger model
(2020-05)Vapor compression systems are the most widely used cooling system type in heating, ventilation, and air-conditioning (HVAC) applications. Two of the four basic components of a vapor compression system are heat exchangers, ... -
Development of tools to accelerate and advance modeling disease progression
(2020-12)Disease pathology emerges from complex interactions at multiple scales including the cellular level, tissue level, and organ level. Multiscale modeling seeks to capture emergent phenomena by coupling models of differing ... -
Evaluating Environmental Influences on Grassland Soil Organic Carbon Temporal and Spatial Distribution
(2019-07)The soil is the largest terrestrial carbon sink, and soil organic carbon (SOC) accounts for twice as much carbon as is stored in the atmosphere. A large portion of recent atmospheric carbon increases is due to the loss of ... -
Evaluating the Impacts of Variable Irrigation Management Strategies on the Performance of Cotton and Grain Sorghum Using Monitoring and Modeling Techniques
(2019-05-01)Diminishing water resources have threatened irrigated agriculture in many semi-arid and arid regions across the globe. In these regions, both surface and groundwater resources have declined due to persistent droughts and ... -
Experimental investigation and simulation of a fluidized-bed gasifier using switchgrass
(2013-12)The overall goal of this research was to improve and optimize yield and composition of syngas generated from biomass gasification using an autothermal lab-scale fluidized-bed gasifier, and to develop a biomass gasification ... -
From Tobacco Road to Tinsel Town: Assessing the Context of Smoking in Movies in Terms of Social Modeling Implications
(Oklahoma State University, 2011-07-01)This study examines the social modeling implications of smoking portrayals in movies as they relate to influencing whether adolescents begin smoking or not. Drawing on the work of Bandura and others, the study identifies ... -
Incorporating the interfacial friction angle concept into the PDC single cutter and full bit modeling
(2019-12)Over the past century, oil and gas served an important role in the US energy sector. The oil industry continually has worked to reduce the drilling cost by increasing drilling efficiency. Drilling is a time-consuming and ... -
