Use of sample entropy to study equine gait lameness.
(2017-08-21)
Administration of a sedative is occasionally required to perform a nerve or joint block
in the horse during the course of a lameness examination. Because sedatives have analgesic
properties, we investigated as to whether ...
Effects of Aging on Microstructure and Mechanical Properties of Lead Free Solder Materials
(2018-12-03)
Lead free solder materials are widely used in the electronic packaging industry due to environmental concerns. However, experimental testing and microstructural characterization have revealed that Sn-Ag-Cu (SAC) lead free ...
Thermal Modeling of the Laser-Powder Bed Fusion Process
(2018-07-24)
Parts fabricated using laser-based additive manufacturing (AM) methods, such as laser-powder bed fusion (L-PBF) receive very high, localized heat fluxes from a laser within a purged, shielding gas (i.e. argon) environment ...
A Nonlinear Model Predictive Control Algorithm for an Unmanned Ground Vehicle on Variable Terrain
(2016-12-12)
This thesis presents a Nonlinear Model Predictive Controller (NMPC) for an Unmanned Ground Vehicle (UGV) capable of controlling the vehicle over both smooth and rough terrain using measurements from GPS and a Light Detection ...
Experimental Evaluation of Immersion-Cooled Strategies for High-Powered Server Modules
(2012-07-19)
Cooling of server-level high-performance computing equipment is an ongoing challenge. Early approaches, based almost entirely on forced air cooling, resulted in unsustainably high energy usage in the air-conditioning units. ...
Investigation of Heat Transfer and Bonding During Material Jetting Additive Manufacturing
(2018-11-15)
Optimum process parameters are critical to achieve deposits of high metallurgical integrity during material jetting additive manufacturing. The most important process parameters include deposition temperature, substrate ...
Parametric Development of Wire 3D Printing
(2015-12-11)
Currently commercialized additive manufacturing techniques offer great detail in small, difficult to produce parts. They are also slow, limited in scale, and expensive. An additive technique that can rapidly produce large ...
Application of Low Melt Alloys as Compliant Thermal Interface Materials: A Study of Performance and Degradation under Thermal Duress
(2016-07-08)
Thermal interface materials (TIMs) are a crucial part of thermal management in micro-electronics and often can account for a significant portion of the overall thermal budget. Generally, materials with high thermal ...
Slow Speed Orthogonal Machining of Polycrystalline FCC BCC HCP Alloys at Various Levels of Hardness using Gaseous Coolants
(2018-11-16)
A statistically designed slow speed orthogonal machining experiment was conducted to compare the effects of various metal-working gases upon the cutting process. Several metals with different crystalline structures and ...
Simultaneous Localization Auto-Calibration and Mapping of Ground Vehicles
(2016-06-17)
This dissertation advances the state of the art of sensor auto-calibration by presenting a generic solution and analysis to the 3D sensor auto-calibration problem, as well as to the 2D simultaneous localization and ...
