Accelerating convergence of leapfrogging optimization - Applications to nonlinear process modeling and nonlinear model predictive control
(2014-07)
Conventionally used optimization methods in chemical engineering applications such as linear programming (LP), Levenberg-Marquardt and sequential quadratic programming (SQP) handle nonlinear objective function (OF) surfaces ...
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 ...
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 ...
PDC drill bit modeling in hard rock
(2020-05)
The objective of thesis is to develop a detailed PDC drill bit ROP model that can be implemented in a real time drilling optimization system for hard rock application. Within the drilling industry, often times operational ...
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, ...
Approach to Modeling and Optimization of Integrated Renewable Energy System (Ires)
(Oklahoma State University, 2013-12-01)
The purpose of this study was to cost optimize electrical part of IRES (Integrated Renewable Energy Systems) using HOMER and maximize the utilization of resources using MATLAB programming. IRES is an effective and a viable ...
Adaptation of a dynamic crop model for estimating tall fescue forage availability in the southern Great Plains
(2022-05)
Due to interannual and cross-location variability of forage production, ranchers oftenencounter difficulties anticipating which management strategies should be used for optimum pastureland management. While models for ...
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 ...
Wet scrubbing of biomass producer gas tars using vegetable oil
(2014-05)
The overall aims of this research study were to generate novel design data and to develop an equilibrium stage-based thermodynamic model of a vegetable oil based wet scrubbing system for the removal of model tar compounds ...
