Paradigms And Paleoartists: How Our Perception Of Dinosaurs Forms, Jordan C. Oldham Apr 2018

Paradigms And Paleoartists: How Our Perception Of Dinosaurs Forms, Jordan C. Oldham

The Research and Scholarship Symposium (2013-2019)

Thomas Kuhn in his famous work The Structure of Scientific Revolutions put forth his idea about how science changes. Kuhn thought that science changed by scientific revolutions brought on by an anomaly. After the anomaly, a crisis point would ensue as more scientists would research the anomaly. While in the process of research they would abandon the old paradigm in favor of one that would explain the anomaly. Not all anomalies create a crisis, but can rather result in a paradigm shift. These shifts occur within the old paradigm, and do not led to the formation of a new paradigm. …

Malware For Macintosh, Nathan C. Shinabarger, Josiah E. Bills, Richard W. Lively, Noah S. Shinabarger

The Research and Scholarship Symposium (2013-2019)

Technology is a cornerstone of modern society. Unfortunately, it seems that every new piece of technology is accompanied by five computer-security breaches elsewhere. Most people associate hacks with Windows computers. This is a problem because Apple computers, and other non-Windows systems, are also extremely vulnerable to attacks and risk being compromised. Dolos is a piece of malware we developed intended to exploit the macOS Sierra operating system. It provides a framework for running exploits and comes built in with certain control and data exfiltration capabilities. Dolos also helps destroy the misconception of "the impenetrable Macintosh computer" by showing that Apple …

On Passing The Buck, Adam J. Hammett, Anna Joy Yang

The Research and Scholarship Symposium (2013-2019)

Imagine there are n>1 people seated around a table, and person S starts with a fair coin they will flip to decide whom to hand the coin next -- if "heads" they pass right, and if "tails" they pass left. This process continues until all people at the table have "touched" the coin. Curiously, it turns out that all people seated at the table other than S have the same probability 1/(n-1) of being last to touch the coin. In fact, Lovasz and Winkler ("A note on the last new vertex visited by a random walk," J. Graph Theory, …


Grain Size Analysis Of Massie’S Creek Near Flax Pond And Community Park, Andrew R. Rivera Apr 2018

Grain Size Analysis Of Massie’S Creek Near Flax Pond And Community Park, Andrew R. Rivera

The Research and Scholarship Symposium (2013-2019)

The goal of this research is to better understand the stream bed conditions at the confluence of North Fork and South Fork Massie’s Creek next to Community Park in downtown Cedarville, OH. Stream depth as well as sediment type where determined as a result of field work done for this project. The depth data was then used to create a contour map of the pool behind the low-head dam that defines the lower boundary of the confluence area. Sediment distribution is represented on this map based on laboratory particle size analysis and gross piratical size analysis done in the field. …


A Hydrologic And Hydraulic Analysis Of Massie’S Creek Gorge, Greene County, Oh, Using Hec-Ras, Joshua W. Perez Apr 2018

A Hydrologic And Hydraulic Analysis Of Massie’S Creek Gorge, Greene County, Oh, Using Hec-Ras, Joshua W. Perez

The Research and Scholarship Symposium (2013-2019)

Massie’s Creek is a small tributary of the Little Miami River, located in southwest Ohio near the village of Cedarville. For approximately 1.5 miles (2.4 km) it flows westward through the Indian Mound Reserve Park, an area which occasionally undergoes flooding. In the first ½ mile (0.8 km) of the park, the stream is confined by a deep gorge, 40 feet (12 m) or more tall, and quickly flattens to a meandering stream through the rest of the park. The present study describes the application of HEC-RAS with the integration of ArcGIS for steady flow analyses and flood inundation mapping, …


The Use Of Drones For Creating 3d Models Of Waterfalls And Bedrock Features, With Particular Attention To Process And Teaching Applications, Campbell F. Bortel Apr 2018

The Use Of Drones For Creating 3d Models Of Waterfalls And Bedrock Features, With Particular Attention To Process And Teaching Applications, Campbell F. Bortel

The Research and Scholarship Symposium (2013-2019)

This study explored the use of Unmanned Aerial Systems (UAS) to model and 3D print waterfalls and bedrock features for use as classroom teaching aids and for possible use in hydrology experiments involving flumes. To achieve the goals of this study, two waterfalls and one bedrock feature were photographed and 3D printed. The waterfalls were Ludlow Falls in Miami County, OH, and Cedar Cliff Falls in Greene County, OH. The bedrock feature was Lizard Head Rock near Sedona, AZ. The UAS platform that was flown was the DJI Mavic Pro quadcopter. A camera mounted on the copter had both videography …
