Design Of Robotic Tram Unit For Field Data Collection, Quetzalcoatl Mendoza Rosas

Open Access Theses & Dissertations

Satellite remote sensing is the most applied method for detection and measurement of electromagnetic energy and its interaction with Earth surface. the analysis of the data acquired can provide important information with uses in areas as like weather forecasting, military intelligence and environmental and resources location. Due to the great distance from where the samples are taken and even with the most sophisticated sensor it is impossible to have an exactly replica of the Earth surface. As a result, scientist analyze imagery where a single pixel can be the representation of a 30 by 30 meters area of land. This …


Superpixel-Based Hyperspectral Unmixing With Regional Segmentation, Mohammed Qassim Alkhatib Jan 2018

Superpixel-Based Hyperspectral Unmixing With Regional Segmentation, Mohammed Qassim Alkhatib

Open Access Theses & Dissertations

Unsupervised unmixing analysis aims to extract the basic materials, also known as, endmembers, and their fractions (or abundances) from a hyperspectral image. In this work, a new unsupervised unmixing approach based on Low Dimensional representation with regional analysis is developed. A low dimensional image representation is obtained using superpixel segmentation where each superpixel is represented by its mean spectra. Regional analysis is then performed using the quadtree segmentation based on the Shannon entropy. Endmembers are extracted from each region and combined using clustering into endmember classes. The proposed approach is tested and validated using the HyDICE Urban, ROSIS Pavia, and …

BACKGROUND & SIGNIFICANCE: Consumption of processed foods high in sodium and fat can have a plethora of health complications, including, but not limited to hypertension, high cholesterol levels, obesity, diabetes and cancer. Previous studies have documented that lack of access to viable healthy eating options' grocery stores selling affordable fresh fruits and vegetables - in any neighborhood or area can result in negative public health outcomes. These areas devoid of such grocery stores and healthy eating options can be classified as "Food Deserts", as per one of the criteria adopted by the United States Department of Agriculture (USDA). In addition, …


Geometry, Timing, And Kinematics Of Neogene Extensional And Transtensional Structures Of Southern Death Valley: Implications For Regional Reconstructions And A Corrective Method For Rigid Body Rotations, Zachariah Fleming Jan 2018

Geometry, Timing, And Kinematics Of Neogene Extensional And Transtensional Structures Of Southern Death Valley: Implications For Regional Reconstructions And A Corrective Method For Rigid Body Rotations, Zachariah Fleming

Open Access Theses & Dissertations

Chapter 1:Advancements in computing capabilities over the last decade have allowed for the routine creation of Structure from Motion-Multiview Stereo (SfM-MVS) terrain models that can serve as base for high resolution geologic mapping. Outcrops models developed from these systems are high-resolution, photo-realistic 3D base providing unprecedented capability for geometric analysis. Yet, before this technology becomes a mainstay of field geology, the potential errors associated with it must be well understood. Here, we compare orientation measurements from multi-point analyses on the SfM-MVS point clouds to those taken in the field with the objective of resolving the geometry of complex folds within …
