Faculty, Staff and Students Publications

In this research, we report a simple hydrothermal synthesis to prepare rhenium (Re)- doped MoS2 flower-like microspheres and the tuning of their structural, electronic, and electrocatalytic properties by modulating the insertion of Re. The obtained compounds were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), high-resolution transmission electron microscopy (HRTEM), Raman spectroscopy, and X-ray photoelectron spectroscopy (XPS). Structural, morphological, and chemical analyses confirmed the synthesis of poorly crystalline Re-doped MoS2 flower-like microspheres composed of few stacked layers. They exhibit enhanced hydrogen evolution reaction (HER) performance with low overpotential of 210 mV at current density of 10 mA/cm2, with a …

Enabling Data-Driven Transportation Safety Improvements In Rural Alaska, F. Lawrence Bennett, Jonathan B. Metzgar, Robert A. Perkins

CSET Project Reports

Safety improvements require funding. A clear need must be demonstrated to secure funding. For transportation safety, data, especially data about past crashes, is the usual method of demonstrating need. However, in rural locations, such data is often not available, or is not in a form amenable to use in funding applications. This research aids rural entities, often federally recognized tribes and small villages acquire data needed for funding applications. Two aspects of work product are the development of a traffic counting application for an iPad or similar device, and a review of the data requirements of the major transportation funding …

Achieving Optimal Horizontal Drill Operations, Daniel J. Serna, James Vasquez, Donald Markley

SMU Data Science Review

In this paper, we present a novel method of predicting the onset of a slide event in horizontal drilling operations. Horizontal drilling operations attempt to create a well through a subsurface as quickly as possible by rotating a drill through the subsurface. A slide event occurs when the drill begins to inefficiently rotate through the subsurface, resulting in a significantly reduced rate of penetration. Slide events can be prevented, or significantly reduced in their impact, when their onset is accurately predicted. We present a method of accurately predicting the onset of slide events with a time-series based predictive model that …

A Data Driven Approach To Forecast Demand, Hannah Kosinovsky, Sita Daggubati, Kumar Ramasundaram, Brent Allen

SMU Data Science Review

Abstract. In this paper, we present a model and methodology for accurately predicting the following quarter’s sales volume of individual products given the previous five years of sales data. Forecasting product demand for a single supplier is complicated by seasonal demand variation, business cycle impacts, and customer churn. We developed a novel prediction using machine learning methodology, based upon a Dense neural network (DNN) model that implicitly considers cyclical demand variation and explicitly considers customer churn while minimizing the least absolute error between predicted demand and actual sales. Using parts sales data for a supplier to the oil and gas …

Pilot Study Of The Contributions Of Achievement-Striving And Dutifulness On Intimate Partner Violence In Intimate Dyads, Ernest M. Oleksy, Liz Goncy

The Downtown Review: An Interdisciplinary Journal Written and Peer-Reviewed by Mandel Honors College Students at Cleveland State University

The purpose of this pilot study was to further our knowledge about the interaction of trait conscientiousness of one’s self and one’s partner with the occurrence of intimate partner violence (IPV) as we prepare for a larger study that will utilize this pilot study’s protocol. Conscientiousness has been demonstrated to be positively correlated with increased satisfaction in couples (Malouff, Thorsteinsson, Schutte, Bhullar, & Rooke, 2010), while different facets of conscientiousness have been demonstrated to have differential effects on relational behavior, like achievement-striving and duty’s opposing effects on commitment dilemmas (Moon, 2001). Furthermore, the negative correlation between conscientiousness and deviance (Rao, …

Comparing The Violent Crime Trends In Select States To The National Trends To Determine Differences Between Crimes, States, And Regions, Alexandra N. Kremer

The Downtown Review: An Interdisciplinary Journal Written and Peer-Reviewed by Mandel Honors College Students at Cleveland State University

Violent crimes include crimes such as murder, rape, robbery, and assault. The FBI in the UCR breaks these down into Type I, crimes against the person, and Type II, property crimes, offenses. The FBI also divides the country into four regions: West, South, Northeast, and Midwest. Each of these regions are examined, through the use of two states from each, here. Their overall violent crime rates and trends, and their specific Type I offensive rates and trends, are examined against the national data and against each other. Several theories are used to explain the potential causes of the differences in …

Brief Literature Review On Conscientiousness And Responsivity To Cbi Programming, Ernest M. Oleksy

The Downtown Review: An Interdisciplinary Journal Written and Peer-Reviewed by Mandel Honors College Students at Cleveland State University

This article reviews the literature of how individual differences (specifically trait conscientiousness) may contribute to ex-offender responsivity to reentry programming. By studying if individual differences (e.g. personality traits) contribute to specific responsivity, programming can be determined to be ineffective for the general population and redesigned in a manner that is beneficial for the largest number of clients. To that end, this literature review provides a conceptual foundation for potential future studies, based on what previous researchers have found in their own studies. With this knowledge, future researchers will be better equipped to make sense of findings once they analyze their …

Physiological Responses To Music, Shauna Cox

The Downtown Review: An Interdisciplinary Journal Written and Peer-Reviewed by Mandel Honors College Students at Cleveland State University

There are numerous ways that people react physically to music, whether it be by choice (like dancing, swaying, etc.) or something that the body carries out on its own, with no intentional or conscious command. These automatic responses from the body could be as basic as heart-rate or respiration, or as complex as biochemical reactions involving hormones and neurotransmitters. In this essay, I will be focusing on those automatic responses.

Integrating Lidar Data And Multi-Temporal Aerial Imagery To Map Wetland Inundation Dynamics Using Google Earth Engine, Qiusheng Wu, Charles B. Lane, Xuecao Li, Kaiguang Zhao, Yuyu Zhou, Nicholas Clinton, Ben Devries, Heather E. Golden, Megan W. Lang

United States Environmental Protection Agency: Publications

The Prairie Pothole Region of North America is characterized by millions of depressional wetlands, which provide critical habitats for globally significant populations of migratory waterfowl and other wildlife species. Due to their relatively small size and shallow depth, these wetlands are highly sensitive to climate variability and anthropogenic changes, exhibiting inter- and intra-annual inundation dynamics. Moderate-resolution satellite imagery (e.g., Landsat, Sentinel) alone cannot be used to effectively delineate these small depressional wetlands. By integrating fine spatial resolution Light Detection and Ranging (LiDAR) data and multi-temporal (2009–2017) aerial images, we developed a fully automated approach to delineate wetland inundation extent at …

Perceptions Of Rural Superintendents On Factors Influencing Employment Decisions, Heather P. Williams, Kathleen Shoup, Lisa Colon Durham, Ben A. Johnson, Shannon Dunstan, Brittany A. Brady, Carl F. Siebert

School Leadership Review

School districts struggle to attract and maintain a sufficient supply of highly capable superintendents. High-needs within rural districts, in particular, often are not able to attract and retain effective leaders. The issue of short superintendent tenure has drawn speculation and concern that revolving leadership may have negative consequences for schools and student achievement. A variety of factors contribute to superintendent turnover including: school board relations, job satisfaction, school district characteristics, and the personal characteristics of superintendents (Grissom & Anderson, 2012; Kamrath & Brunner, 2014; Wood, Finch & Mirecki, 2013). This study provides insight into perceptions of rural superintendents (n=10) and …

Safeguarding Biometric Authentication Systems From Fingerprint Spoof Attacks, Firas Sammoura, Jean-Marie Bussat

Defensive Publications Series

This publication describes processes, methods, and techniques of safeguarding biometric authentication systems from fingerprint spoof attacks. A fingerprint spoof attack occurs when a malicious party attempts to access a user’s computing device by mimicking/replicating biometric identifiers inherent to the user’s fingerprint. To prevent fingerprint spoof attacks, an improved biometric authentication protocol includes, in a first step, verifying a user’s identity and, in a second step, determining if the finger presented is alive. As a result, fingerprint spoof attacks can be rejected when it is determined that the spoof finger does not exhibit characteristics of life.
