Uncertainty Of Stereo Piv Calibration And Self-Calibration, Braydon J. Williams 2017 Utah State University

Uncertainty Of Stereo Piv Calibration And Self-Calibration, Braydon J. Williams

All Graduate Theses and Dissertations

Particle image velocimetry (PIV) is a widely used fluid measurement technique. Three dimensional PIV data or stereo PIV is acquired using two cameras. Stereo cameras are calibrated from camera coordinates, pixels, to real world units such as millimeters using calibration models. Stereo calibration is fundamental to the accuracy of a PIV measurement. In this thesis, the accuracy of the stereo calibration is assessed. The mean error of stereo calibration was found to be 0.23%.

Investigation Of Subjective Perception & Objective Metrics Of Acoustic Room Diffusion, Jay Michael Bliefnick

Architectural Engineering -- Dissertations and Student Research

While a variety of assessment methodologies have been proposed to quantify acoustic diffusivity within rooms, a link between these and the perception of diffusion has not been fully established. This study investigated various ways of analyzing diffusion, through both human perception and objective metrics. Numerous impulse response measurements were collected from a physical acoustics testing facility designed for diffusion research. This space featured reversible absorptive/diffusive/reflective wall panels, which allowed numerous testing configurations. One such setup investigated how changing the diffusivity of an isolated wall surface impacted diffusive room conditions. Alternatively, the effects diffuser configurations had on diffusive room ...

Collecting, Preparing, And Synthesizing Well Log Data For Subsurface Mapping: Example From The Bakken Formation, Asel Sherimkulova

Graduate Theses & Non-Theses

Late Devonian and Early Mississippian Bakken Formation consists of three distinct members: the upper shale, middle, and lower shale. The upper and lower shales are excellent source rocks, rich in organic content. The organic material in the shales was derived from planktonic algae. Both the upper and lower shales were deposited during a transgressive event in hypoxic to anoxic conditions. The original total organic carbon content in the Bakken shales ranges from 20 to 22 weight percent, however; the content decreases to 10 to 17 weight percent as a result of maturation of hydrocarbons and primary expelling of oil. High ...

Proposal Of Hybrid Damping Package Design, Qi Zhang, Katsuhiko Saito, Katsushige Nagaoka 2016 Graduate School of Maritime Sciences, Kobe University

Proposal Of Hybrid Damping Package Design, Qi Zhang, Katsuhiko Saito, Katsushige Nagaoka

Journal of Applied Packaging Research

To protect products from shock and vibration during transport, Cushioning Packaging Design is implemented. The cushioning performance and anti-vibration performance of a package is tested by a drop test and a vibration test. The effectiveness of the cushioning during a drop test is predictable because the cushioning material`s thickness and bearing area are determined by the cushion curves which are plotted based on the results of the tests. However, an effective package-design method which can predict the package vibration of all the static stresses that are suitable for cushioning package design has not been established yet.thus, it remains ...

Designing And Building An Automatic Chamfer Grinder, William Johnson

Honors College Capstone Experience/Thesis Projects

Modern day manufacturing is a demanding environment with a constant need for process improvement. As automation becomes more advanced, there are fewer jobs that must be completed by a human. In the case of Stupp Bridge Company, a local manufacturer of steel bridge girders, their workforce is highly skilled, so replacing mundane tasks with automation allow the skilled workers to focus on the difficult jobs. One such task is grinding a chamfer onto every leading edge of each girder flange, eight edges in total, ranging from 20 to 200 feet long. The purpose of this project was to design an ...

Optimization Of A High-Speed X-Ray Imaging System For Studying Sprays, Lane E. Schultz, Mikhail N. Slipchenko, Terrence R. Meyer, Wilbert C. Slowman

The Summer Undergraduate Research Fellowship (SURF) Symposium

Spray-based liquid atomization and liquid mixing is critical for development of efficient combustors and drug delivery systems as well as multiple coating-related applications. While optical methods allow characterization of low density regions of sprays, the scattering of optical photons hinders the characterization of a dense core. Unlike optical photons, higher-energy X-ray photons have the capability to penetrate and image the core structure of sprays. Here we characterized temporal and spatial resolution of an X-Ray imaging system based on a commercially available tube source with an anode size of 0.6 mm. For high-speed imaging, a phosphor screen in combination with ...

Predicting The Effect Of Gaps Between Pallet Deckboards On The Compression Strength Of Corrugated Boxes, Matthew Baker, Laszlo Horvath, Marshall S. White 2016 Virgina Polytechnic Institute & State University, USA

Predicting The Effect Of Gaps Between Pallet Deckboards On The Compression Strength Of Corrugated Boxes, Matthew Baker, Laszlo Horvath, Marshall S. White

Journal of Applied Packaging Research

The majority of corrugated boxes are transported and stored on pallets where the reduced support area due to deckboard gaps has an adverse effect on the strength of the corrugated boxes Therefore, an adjustment factor is used to adjust the box compression strength to account for the lack of support, but these factors were developed for a limited range of deckboard gaps, box sizes, and box orientations. In addition, there is no predictive model that can estimate the reduction in compression strength based on the size of the box and the size of the gap. The main objective of this ...


Ir-Based Estimation Of Velocities Above Flames Spreading Over Different Fuels, Lulu Sun, Xiangyang Zhou, David R. Weise, Shankar Mahalingam 2016 Embry-Riddle Aeronautical University - Daytona Beach

Ir-Based Estimation Of Velocities Above Flames Spreading Over Different Fuels, Lulu Sun, Xiangyang Zhou, David R. Weise, Shankar Mahalingam

Lulu Sun

Wildfire spread in living vegetation such as chaparral in California and eucalyptus forests in Australia often causes significant damage to infrastructure and ecosystems. A physically based empirical model to predict fire spread rate is used in the United States to assist in a variety of fire management operations. The spread model does not adequately describe the chemical processes of combustion in live fuels.

Prior to describing and modeling the chemical processes of combustion in wildland fuels using computational fluid dynamics, we are investigating a technique to non-intrusively measure flame gas velocities using thermal imagery. By tracing "hot" pixels through successive ...
