Form and Functionality of Additively Manufactured Parts with Internal Structure
(North Dakota State University, 2019)
The tool-less additive manufacturing (AM) or 3D printing processes (3DP) use incremental consolidation of feed-stock materials to construct part. The layer by layer AM processes can achieve spatial material distribution ...
Stochastic Optimization of Sustainable Industrial Symbiosis Based Hybrid Generation Bioethanol Supply Chains
(North Dakota State University, 2013)
Bioethanol is becoming increasingly attractive for the reasons of energy security, diversity, and sustainability. As a result, the use of bioethanol for transportation purposes has been encouraged extensively. However, ...
Optimization Models for Scheduling and Rescheduling Elective Surgery Patients Under the Constraint of Downstream Units
(North Dakota State University, 2013)
Healthcare is a unique industry in terms of the associated requirements and services provided to patients. Currently, healthcare industry is facing challenges of reducing the cost and improving the quality and accessibility ...
Assessing Reliability of Highly Reliable Products Using Accelerated Degradation Test Design, Modeling, and Bayesian Inference
(North Dakota State University, 2019)
The accelerated degradation test methods have proven to be a very effective approach to quickly evaluate the reliability of highly reliable products. However, the modeling of accelerated degradation test data to estimate ...
The Effect of Stress on Task Capacity and Situational Awareness
(North Dakota State University, 2012)
In today’s industry, many occupations require manpower resources to include both labor and cognitive resources. As the technology is rapidly changing and businesses are becoming more dependent on cognitive performance, it ...
Integrated Projection and Regression Models for Monitoring Multivariate Autocorrelated Cascade Processes
(North Dakota State University, 2014)
This dissertation presents a comprehensive methodology of dual monitoring for the multivariate autocorrelated cascade processes using principal component analysis and regression. Principle Components Analysis is used to ...
Designing Bio-Ink for Extrusion Based Bio-Printing Process
(North Dakota State University, 2019)
Tissue regeneration using in-vitro scaffold becomes a vital mean to mimic the in-vivo counterpart due to the insufficiency of animal models to predict the applicability of drug and other physiological behavior. Three-dimensional ...
Improvement of Wind Forecasting Accuracy and its Impacts on Bidding Strategy Optimization for Wind Generation Companies
(North Dakota State University, 2012)
One major issue of wind generation is its intermittence and uncertainty due to the highly volatile nature of wind resource, and it affects both the economy and the operation of the wind farms and the distribution networks. ...
Optimization of Large-Scale Sustainable Renewable Energy Supply Chains in a Stochastic Environment
(North Dakota State University, 2014)
Due to the increasing demand of energy and environmental concern of fossil fuels, it is becoming increasingly important to find alternative renewable energy sources. Biofuels produced from lignocellulosic biomass feedstock's ...
A Semiparametric Trajectory Model for Cognitive Decline
(North Dakota State University, 2017)
Dementia is a group of diseases that are caused by neurocognitive disorder. It is the second leading cause of death in older adults in the US. People who suffer from dementia experience memory loss and other cognitive or ...
