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%.


Balancing The Navigational Safety, Efficiency & Financial Aspects Of Oreis, Raza Ali Mehdi 2017 World Maritime University

Balancing The Navigational Safety, Efficiency & Financial Aspects Of Oreis, Raza Ali Mehdi

MARENER 2017

The increasing number and sizes of offshore renewable energy installations (OREIs), combined with the ambitious plans for future developments in the sector, portray a bleak outlook for ‘traditional’ maritime and marine players: if the current plans for OREIs are realized, sea-space will become increasingly restricted for activities such as shipping.

Sustained growth of both OREIs and shipping may thus lead to situations where certain risk control options (RCOs) need to be adapted in order to maintain safety – despite the fact that such measures themselves may be counter-productive in terms of energy efficiency or financial sustainability. This leads to the question ...


See The Bigger Picture: A True Systems Approach To Healthcare, Brian J. Galli 2017 Long Island University

See The Bigger Picture: A True Systems Approach To Healthcare, Brian J. Galli

Faculty of Computer Science/Management Engineering Publications

“Healthcare” is typically related directly to patient care, hospitals, and ambulatory services, but it is important to see that healthcare is beyond just the delivery of care in hospitals or ambulatory services. A more accurate systems approach to views the world of healthcare as one that involves several stakeholders, including: healthcare delivery (patient care in hospitals and ambulatory services), regulatory agencies, health insurance/health plan organizations, medical device design and manufacturers, pharmaceuticals, society, government (all levels), and healthcare reform organizations. All of these stakeholders relate to each other in many levels and impact our healthcare system.

A Case Study Of Upper-Room Uvgi In Densely-Occupied Elementary Classrooms By Real-Time Fluorescent Bioaerosol Measurements, Chunxiao Su, Josephine Lau, Fang Yu

Architectural Engineering -- Faculty Publications

Recently, the requirement to continuously collect bioaerosol samples using shorter response times has called for the use of real-time detection. The decreased cost of this technology makes it available for a wider application than military use, and makes it accessible to pharmaceutical and academic research. In this case study, real-time bioaerosol monitors (RBMs) were applied in elementary school classrooms—a densely occupied environment—along with upper-room ultraviolet germicidal irradiation (UVGI) devices. The classrooms were separated into a UVGI group and a non-UVGI control group. Fluorescent bioaerosol counts (FBCs) were monitored on 20 visiting days over a four-month period. The classroom ...

This paper will describe a synopsis of the development and application of a survey instrument to assess team skills and professional development outcomes of Team-Based Learning (TBL) in a human factors course. TBL is an advancing teaching pedagogy that shifts instruction from a traditional lecture-based teaching paradigm to a structured learning sequence that includes individual student preparation outside of class followed by active, in-class problem solving exercises completed by student learning teams. As an evolving teaching method, TBL appears to be producing new empirical learning outcomes in areas that have only preliminarily been explored. Traditionally, the effectiveness of TBL has ...

A real-time, on-line scatterometry system has also been demonstrated and proven to provide a high throughput measurement.

Three different types of samples have been measured using the scatterometry setup. The wire-grid polarizer (WGP) sample has been made by Jet and Flash Nanoimprint Lithography with ~100 nm pitch and ~50 nm wide ~200 nm tall Al gratings on ...


Investigation Of Subjective Perception & Objective Metrics Of Acoustic Room Diffusion, Jay Michael Bliefnick 2016 University of Nebraska-Lincoln

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 ...

Experimental Investigation Of The Velocity Field In Buoyant Diffusion Flames Using Piv And Tpiv Algorithm, Lulu Sun, Xiangyang Zhou, Shankar Mahalingam, David R. Weise

Lulu Sun

We investigated a simultaneous temporally and spatially resolved 2-D velocity field above a burning circular pan of alcohol using particle image velocimetry (PIV). The results obtained from PIV were used to assess a thermal particle image velocimetry (TPIV) algorithm previously developed to approximate the velocity field using the temperature field, simultaneously captured by an infrared (IR) thermal camera. By tracing “thermal particles,” which were assumed to be virtual particles that corresponded to pixels of temperature values in successive IR images, the TPIV algorithm estimated a larger scale instantaneous velocity field than either a single-point velocity measurement (e.g., LDV) or ...

Using Photogrammetry To Document, Analyze, And Reverse-Engineer Grave Markers, Robert Z. Selden Jr.

Robert Z. Selden Jr.

There are a wide range of applications for three-dimensional (3D) data in archaeology, and a diverse array of methods for collecting and analyzing those data. In this article, free 3D photogrammetry software (Autodesk 123D Catch) is used to document a series of grave markers. The data are subsequently exported to Geomagic Design X to demonstrate and briefly discuss the various potential analyses that might be used to illustrate the effects of preservation treatments and marker degradation through time. Further, one marker is reverse-engineered, illustrating the capacity of 3D modeling to expedite the process of design, should elements warrant replacement. Additional ...

High Power Optically Pumped Semiconductor Lasers For Sodium Guidestar Applications, Shawn W. Hackett 2016 University of New Mexico

High Power Optically Pumped Semiconductor Lasers For Sodium Guidestar Applications, Shawn W. Hackett

Optical Science and Engineering ETDs

Optically pumped semiconductor lasers (OPSLs) are shown to provide a much more compact and less expensive source for illumination of the sodium layer of the mesosphere for use as a sodium laser guidestar via single and two photon excitation schemes. This represents a revolution in laser guidestar technology as the cost, size, and power requirements for a laser guidestar system are shown to have been decreased by an order of magnitude with guidestar performance shown to be similar to previous sources. Sodium laser guidestar sources for broadband simultaneous illumination of multiple lines are developed and simulated. Simulations are then compared ...


Distributed Fiber-Optic Temperature Sensor Validations Using Field Deployments In The Flooded Orphan Boy Mine Shaft In Butte, Mt, Elliott Mazur 2016 Montana Tech

Distributed Fiber-Optic Temperature Sensor Validations Using Field Deployments In The Flooded Orphan Boy Mine Shaft In Butte, Mt, Elliott Mazur

Graduate Theses & Non-Theses

The process of sensor validation through experimentation with the Omnisens Distributed Temperature and Strain (DITEST) Brillouin Optical Time Domain Analyzer (BOTDA) proved to be a challenging project. The project encompassed sensor calibrations, system error minimization, sensor network design and deployment, and the characterization of temperatures in the Orphan Boy Mine shaft. Fiber-optic cable sensor calibrations yielded linear relationship coefficients 0.6-1.0MHZ/°F, indicating a strong positive correlation between Brillouin Frequency Shifts and temperature. Calibrated sensors demonstrated accuracies near ±0.8°F using the corrected error bounds from residual analyses as the benchmark. Fiber-optic measurement accuracy and repeatability were controlled ...


Collecting, Preparing, And Synthesizing Well Log Data For Subsurface Mapping: Example From The Bakken Formation, Asel Sherimkulova 2016 Montana Tech

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 ...
