A combined analytical and experimental approach for prediction of properties of Fused Deposition Modeling (FDM) parts
(University of Missouri--Columbia, 2020)Fused Deposition Modeling (FDM) is a technique used to build rapid prototypes out of thermoplastic materials. Printing technology continues to mature from a rapid prototyping process to a rapid manufacturing technique, ... -
Compact oscillating heat pipe and development of fuzzy copper or wicking structures
(University of Missouri--Columbia, 2008)A central processing units (CPU) calculation speed is limited by the heat it produces. As the number of transistors and the clock speed of CPUs increase they become more powerful, but they also generate more heat which ... -
A comparison of modeling techniques: using the finite element method to determine local displacements in a human hip
(University of Missouri--Columbia, 2007)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Artificial hip implant surgery is required by approximately 120,000 Americans each year. A typical hip replacement requires the surgical insertion of ... -
A comprehensive model for energy transport and ablation of metal films induced by ultrashort pulsed lasers
(University of Missouri--Columbia, 2012)A comprehensive laser material ablation model was developed to describe energy transport, ultrafast phase changes, and material ablation of metal films irradiated by ultrashort laser pulses. The two optical models were ... -
Comprehensive optimization for thermoelectric refrigeration devices
(University of Missouri--Columbia, 2005)A large market is currently in place for which thermoelectric (TE) technology can provide diverse energy solutions. This market should continue to grow as improvements are made to TE materials. In the last 10-15 years, ... -
A comprehensive simulation-based methodology for the design and optimization of orthopaedic internal fixation implants
(University of Missouri--Columbia, 2011)Internal fixation implants are widely used by orthopaedic surgeons to stabilize various types of fractures in injured patients. However, the irregular geometry of the human skeletal system, as well as the significant ... -
Condition monitoring of an axial piston pump utilizing the Kalman filter
(University of Missouri--Columbia, 2018)Condition monitoring of a hydraulic pump is an essential process for maximum operational time and pump life longevity. One method of condition monitoring is to estimate parameters characterized by flow losses. Even in a ... -
Condition-based monitoring system for diagnostics and prognostics of centrifugal pumps
(University of Missouri--Columbia, 2016)Centrifugal pumps are the most commonly used pumps in industry. Therefore, maintenance is a very important part of the pump's life cycle. This work presents a systematic robust conditionbased monitoring process for diagnostics ... -
Control of arterial hemoglobin saturation in premature infants using H-infinity synthesis and performance specifications from best clinical practice
(University of Missouri--Columbia, 2013)This work details the development of a novel control system for regulating the Arterial Hemoglobin saturation (SpO2) of premature infants. An H-infinity synthesis method was used to derive multiple controllers to cover a ... -
Controlling the kinematics of the left ventricle to treat resistant hypertension
(University of Missouri--Columbia, 2018)The intention of this thesis is to present a novel controller design that eliminates hypertension in patients who suffer from resistant hypertension. The controller is designed by first translating the functionality of the ... -
Cooperative control of multi-agent systems with time-delays
(University of Missouri--Columbia, 2018)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] In this dissertation, we designed two cooperative control algorithms for multi-agent systems with time-delays. The first one is Robust Sliding-Mode ... -
Cruise flight optimization of a commercial aircraft with winds
(University of Missouri--Columbia, 2015)With high prices for fuel and airfare, companies are looking to minimize operational costs. Reducing aircraft fuel consumption is one strategy companies use to lower costs. During flights, commercial aircraft divide the ... -
Damage inspection of isotropic/multi-layer plates by time-frequency analysis of Lamb waves
(University of Missouri--Columbia, 2014) -
Damping and stiffening forces of a squeeze-film between two plates
(University of Missouri--Columbia, 2016)Silicon microstructures, especially sensors and actuators, are characterized by squeeze film between the moving elements and the fixed substrates. The effect of the squeeze film has been represented by the damping effect ... -
Dental composites reinforced with zinc oxide nanofillers
(University of Missouri--Columbia, 2012)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Dental composites suffer from inadequate mechanical properties and formation of secondary caries, which could lead to the increased failure rate of ... -
The Design and analysis of a HA/PLA pedicle screw for spinal fusion
(University of Missouri--Columbia, 2011)Metallic pedicle screws have been widely used in the orthopaedic field to treat spinal diseases. Although spinal screws have improved over the last few decades, there is still sometimes a need for a second painful surgery ... -
Design and analysis of origami-inspired structures
(University of Missouri--Columbia, 2022)This work focuses on creating novel structures by combining elements of common origami patterns. Multiple different types of physical and computer models are implemented to represent and analyze the structures. These ... -
Design and experimental testing of metamaterial-based agitators
(University of Missouri--Columbia, 2016)Due to the low heat rejection capacity or huge water consumption of traditional cooling methods, many power plants are looking for a way that is eco-friendly and high efficient but low-cost to retrofit their current cooling ... -
The design and implementation of an endoscopic enabled mouth gag
(University of Missouri--Columbia, 2016)The purpose of this project was to design and produce a working prototype of a device that could be used in upper airway Otolaryngology surgeries to increase nasopharynx visualization. The nasopharynx is the anatomical ... -
Design and optimization of a Mars sample return mission with nuclear thermal rockets
(University of Missouri--Columbia, 2011)Nuclear thermal propulsion (NTP) is recognized as the only solution to human exploration of the near planets during the next several decades, but NTP currently receives little funding for development. In order to foster ...
