Hybridization of Bast Natural and Synthetic Fibers in Thermoplastic Composites
(North Dakota State University, 2019)
In recent years, the use of natural fiber-reinforced composites in more advanced applications has grown substantially. Applications of high strength require high mechanical properties. An effective method for increasing ...
Dynamic Stall Characteristics of a Pitching Swept Finite Aspect Ratio Wing
(North Dakota State University, 2019)
This research will investigate various swept wing models, designing the mechanism for their pitching motion and control, designing wind tunnel implementation, and performing data measurements and analysis using particle ...
Unsteady Aerodynamics and Turbulent Near-Wake Characterization of Static and Rotating Cylinder Sytems
(North Dakota State University, 2018)
External flows around bluff bodies have been broadly investigated due to their great importance in engineering applications including aircraft and missile development, marine and naval structures, vehicle aerodynamics, ...
Cavitation Inception and Contaminant Effects
(North Dakota State University, 2014)
Within a liquid, it is possible to lower the pressure to a point in which the nuclei gas bubbles will cause cavitation inception. During this drop in pressure, at constant temperature, the bubble tension will increase to ...
Dynamic Modelling for the Path Tracking Control of a Four-Wheel Independent-Drive, Four-Wheel Independent-Steer Autonomous Ground Vehicle
(North Dakota State University, 2017)
Robots that can be reconfigured to perform more than one task would be to consumers. The Four-Wheel Independent-Drive, Four-Wheel Independent-Steer (4WD4WS) robot is well suited for the role of reconfigurable robot due to ...
Robust Control of Skid Steered Robotic Vehicles on High Friction Surfaces
(North Dakota State University, 2015)
The autonomous control of unmanned ground vehicles (UGVs) is a growing research area. Skid steered UGVs are desired because of their simple control inputs, however the control algorithm requires complex dynamic analysis. ...
Fluid Dynamics of Material Micro-Deposition: Capillary-Based Droplet Deposition and Aerosol-Based Direct-Write
(North Dakota State University, 2012)
With rapid development of the direct-write technology, in addition to requirement of non-destructive printing, there is a need for non-expensive, robust, and simplified techniques of micro/nano fabrication. This dissertation ...
Characterization of Regenerated Silk Material for Biomimetic Spinning and Film Casting
(North Dakota State University, 2018)
Natural silks produced by spiders and silkworms exhibit tailorable mechanical performance yet to be achieved synthetically. This phenomenon is derived from a biological system that has been evolutionarily optimized. In ...
Nanomechanical Characterization of Tobacco Mosaic Virus Superlattice with Novel Atomic Force Microscopy Methods
(North Dakota State University, 2013)
Tobacco mosaic virus (TMV) has been widely studied due to its excellent properties. In order to utilize TMV superlattice, this thesis initiates the study on its mechanical properties. The elastic modulus of TMV superlattice ...
Dried Distillers Grains With Solubles as a Multifunctional Filler in Wood Particleboards
(North Dakota State University, 2015)
Dried Distillers Grains with Solubles (DDGS) has been investigated for its use as a functional filler in wood particleboards bonded with Melamine Urea Formaldehyde. Both the concentration of the DDGS filler – 5, 10, and ...
