Towards Systematic Selection Of Terrain- And Ground Cover-Specific Lidar Filtering Parameters, Vance Green

Graduate Theses and Dissertations

Accurate automated classification of LiDAR point clouds is a well-known problem and proper parameterization of the classification algorithm is essential to creating useful bare-earth terrain models. Parameterization is particularly important in areas characterized by extremely low relief, such as the Little Red River Irrigation Project Area in central Arkansas. In this kind of landscape, analyses such as hydrological flow models are sensitive to small changes in the topography, and therefore prone to errors in the classification of the LiDAR point cloud and the digital elevation models (DEMs) derived from it. Developing effective project-specific parameters requires a high degree of knowledge …

A Simulation Platform For Accurate Prediction Of In-Bin Drying And Storage Of Rough Rice, Houmin Zhong

Graduate Theses and Dissertations

Natural air (NA), in-bin drying and storage of rough rice generally maintains high grain quality, but the associated slow movement and occasional stagnation of the drying front during the process may result in problems of rice quality reduction, mold growth, and mycotoxin development, especially for rough rice in the top layers of the bin. Using modeling techniques to simulate in-bin rough rice drying in typically-encountered field scenarios may provide a tool for rapidly predicting the grain condition as drying progresses. The objectives for this study were to (1) investigate accurate models for predicting equilibrium moisture content (EMC) of rough rice …

On The Evolutionary Origins Of Religious Belief, Robert Duane Howard

Graduate Theses and Dissertations

Religious belief is a byproduct of evolutionarily designed cognitive mechanisms. The ubiquity of religious belief and experience across human cultures is explained by our common human psychology; our domain-specific cognitive mechanisms give rise, collectively, to the phenomenon of byproduct religious belief/experience. In this thesis, I will examine what I call religion-generating cognitive mechanisms, and I will argue that byproduct raw god-beliefs are developed by cultures into refined god-beliefs. These refined god-beliefs are co-opted by evolutionary processes and are cultural adaptations. My conception of “religious belief” in terms of raw and refined god-beliefs allows a disambiguation of the term “religion,” and …

Geospatial Workflows And Trust: A Use Case For Provenance, Rachel Frances Linck

Graduate Theses and Dissertations

At first glance the Astronomer by Vermeer, Tutankhamun’s burial mask, and a geospatial workflow may appear to have nothing in common. However, a commonality exists; each of these items can have a record of provenance detailing their history. Provenance is a record that shows who did what to an object, where this happened, and how and why these actions took place. In relation to the geospatial domain, provenance can be used to track and analyze the changes data has undergone in a workflow, and can facilitate scientific reproducibility. Collecting provenance from geospatial workflows and finding effective ways to use this …

Validation Of Soil-Test-Based Phosphorus And Potassium Fertilizer Recommendations For Rice And Soybean, Matthew Scott Fryer

Graduate Theses and Dissertations

The science of soil-testing for nutrient management and fertilizer recommendations is widely accepted among scientists and agronomists.

However, the research also showed that there is still a large gap in the number of males and females working in Science, Technology, Engineering, and Mathematics (STEM) careers. This study also investigated this trend within western Arkansas to determine whether the gender gap in STEM is caused …

Baby Mama: Appellate Court Declares Sherri Shepherd Is The Legal Mother Of A Child Born To Her Via Surrogate, Joanna L. Grossman

Hofstra Law Faculty Scholarship

Although surrogacy ostensibly dates to biblical days—Abraham and Sarah’s handmaiden, Hagar, for example—it is quintessentially a modern path to parenthood. In its initial iteration, so-called traditional surrogacy, the arrangement called for artificial insemination of the surrogate carrier with sperm from the intended father, whose wife provided no genetic material but was the intended mother and a party to the contract. As reproductive technology advanced, and in vitro fertilization was first developed and then improved, a new type of surrogacy became the norm. With gestational surrogacy, the carrier provides only the womb, while both egg and sperm come from the intended …
