Journal of Human Performance in Extreme Environments
We used a field excursion to the West Clearwater Lake Impact structure as an opportunity to test factors that contribute to the decisions a remote field team (for example, astronauts conducting extravehicular activities (EVA) on planetary surfaces) makes while collecting samples for return to Earth. We found that detailed background on the analytical purpose of the samples, provided to the field team, enables them to identify and collect samples that meet specific analytical objectives. However, such samples are not always identifiable during field reconnaissance activities, and may only be recognized after outcrop characterization and interpretation by crew and/or science team …
Estimating The Water Quality Condition Of River And Lake Water In The Midwestern United States From Its Spectral Characteristics, Jing Tan
Open Access Dissertations
This study focuses on developing/calibrating remote sensing algorithms for water quality retrieval in Midwestern rivers and lakes. In the first part of this study, the spectral measurements collected using a hand-held spectrometer as well as water quality observations for the Wabash River and its tributary the Tippecanoe River in Indiana were used to develop empirical models for the retrieval of chlorophyll (chl) and total suspended solids (TSS). A method for removing sky and sun glint from field spectra for turbid inland waters was developed and tested. Empirical models were then developed using a subset of the field measurements with the …
Image Segmentation Using Fuzzy-Spatial Taxon Cut, Lauren Barghout
Image Segmentation Using Fuzzy-Spatial Taxon Cut, Lauren Barghout
MODVIS Workshop
Images convey multiple meanings that depend on the context in which the viewer perceptually organizes the scene. This presents a problem for automated image segmentation, because it adds uncertainty to the process of selecting which objects to include or not include within a segment. I’ll discuss the implementation of a fuzzy-logic-natural-vision-processing engine that solves this problem by assuming the scene architecture prior to processing. The scene architecture, a standardized natural-scene-perception-taxonomy comprised of a hierarchy of nested spatial-taxons. Spatial-taxons are regions (pixel-sets) that are figure-like, in that they are perceived as having a contour, are either `thing-like', or a `group of …
Two Correspondence Problems Easier Than One, Aaron Michaux, Zygmunt Pizlo
Two Correspondence Problems Easier Than One, Aaron Michaux, Zygmunt Pizlo
MODVIS Workshop
Computer vision research rarely makes use of symmetry in stereo reconstruction despite its established importance in perceptual psychology. Such stereo reconstructions produce visually satisfying figures with precisely located points and lines, even when input images have low or moderate resolution. However, because few invariants exist, there are no known general approaches to solving symmetry correspondence on real images. The problem is significantly easier when combined with the binocular correspondence problem, because each correspondence problem provides strong non-overlapping constraints on the solution space. We demonstrate a system that leverages these constraints to produce accurate stereo models from pairs of binocular images …
Automated Segmentation, Detection And Fitting Of Piping Elements From Terrestrial Lidar Data, Yun-Ting Su
Automated Segmentation, Detection And Fitting Of Piping Elements From Terrestrial Lidar Data, Yun-Ting Su
Open Access Dissertations
Since the invention of light detection and ranging (LIDAR) in the early 1960s, it has been adopted for use in numerous applications, from topographical mapping with airborne LIDAR platforms to surveying of urban sites with terrestrial LIDAR systems. Static terrestrial LIDAR has become an especially effective tool for surveying, in some cases replacing traditional techniques such as electronic total stations and GPS methods. Current state-of-the-art LIDAR scanners have very fine spatial resolution, generating precise 3D point cloud data with millimeter accuracy. Therefore, LIDAR data can provide 3D details of a scene with an unprecedented level of details. However, automated exploitation …
Investigation Of Industry Perceptions Of Building Information Modeling (Bim)-Based Estimating Practices In The U.S. And China, Zhihang Yi
Open Access Theses
While the Building Information Modeling (BIM) technology has been seen as next revolutionary technology for the Architectural, Engineering, Construction and Facility Management (AEC/FM) fields, the AEC/FM industry does not implement BIM technology on the cost estimating practices as widely as expected. The efficiency improvement on cost estimating with BIM could be accomplished through automating quantity take-offs, closely collaborating design with the estimating professionals and so on. This research explores the advantages and barriers of imbedding BIM technology into the estimating practices which enables the industry deepen their understandings on BIM-based cost estimation method. This study also compares the industry perceptions …
International Water And Food Security Development: Performance Evaluation And Assessment Of Research Needs At Multiple Scales, Caitlin Anne Grady
International Water And Food Security Development: Performance Evaluation And Assessment Of Research Needs At Multiple Scales, Caitlin Anne Grady
Open Access Dissertations
Water and food security remain the top development challenges of the decade, and perhaps the century. Since the Millennium Development Goals were established in 2000, billions of people have obtained access to more food, better nutrition, improved water, and basic sanitation facilities worldwide. This progress has been accomplished through the dedication of international organizations, non-governmental organizations, country-level governments, private corporations, and individuals at international, regional, and local scales. Truly tremendous strides have been made in water and food provisioning for humans worldwide. These past two decades have also seen the largest population growth on record, the highest rates of childhood …
A Probabilistic Model Of Benefit-Cost Analysis For Highway Construction Projects, Yue He
A Probabilistic Model Of Benefit-Cost Analysis For Highway Construction Projects, Yue He
Open Access Theses
Deterministic method occupies the predominant position in economic analysis. However, by using a single value to estimate the project value, deterministic method would hide the risk under it. Analysts may make incorrect judgments by looking at a value without knowing the likelihood of its occurrence and the consequences of its occurrence. A probabilistic model was developed in this study to address this problem. It was found in this study that the traffic flows on Indiana highways follow logistic distributions rather than normal distributions as generally believed. The application of the probabilistic model was illustrated through a case study. The results …
Waste And Duplication In Nasa Programs: The Need To Enhance U.S. Space Program Efficiency, Bert Chapman
Waste And Duplication In Nasa Programs: The Need To Enhance U.S. Space Program Efficiency, Bert Chapman
Libraries Faculty and Staff Scholarship and Research
The U.S. Government faces acute budgetary deficits and national debt problems in the Obama Administration. These problems have been brought about by decades of unsustainable government spending affecting all agencies including the National Aeronautics and Space Administration. (NASA). An outgrowth of this fiscal profligacy is the presence of wasteful and duplicative programs within NASA that prevent this agency from achieving its space science and human spaceflight objectives. These problems occur due to mismanagement of these programs from NASA and the creation of these programs by the U.S. Congress and congressional committees. This occurs because congressional appropriators tend to be more …
Eco-Design Integration Into New Product Development Processes: Comparison Between Lca Software And Cad-Integrated Tools, Maria I. Hernandez Dalmau
Eco-Design Integration Into New Product Development Processes: Comparison Between Lca Software And Cad-Integrated Tools, Maria I. Hernandez Dalmau
Purdue Polytechnic Masters Theses
The constant growth of environmental concerns and in order to satisfy the increasing population demands, designers have started to integrate eco-design parameters in early design stages. The technological development that happened in the last decade has started to integrate LCA methods within CAD tools, allowing non-geometric data to be integrated in a typical geometrical model. The main research interest of this thesis is focused on the evaluation of the use of these emerging CAD tools, as tools capable to evaluate the futures environmental impacts of products and processes. This thesis studies through three comparative case studies if SolidWorks Sustainability as …
