Cybersecurity Education Employing Experiential Learning, Travis Lowe, Casey Rackley

KSU Proceedings on Cybersecurity Education, Research and Practice

ABSTRACT

The purpose of this paper is to discuss a curriculum design that employs Kolb’s Experiential Learning Theory stages and Kolb’s Learning Styles in four consecutive class sessions. The challenge each class is to present students with perplexing and often frustrating network problems that someday might be encountered on the job. By using Kolb’s theory, students address those problems from the perspective of each learning style, while passing through each phase of the learning cycle. As a result, students gain stronger cognitive thinking skills and hands-on troubleshooting skills in preparation for work as network administrators or cybersecurity analysts.

Study Of Physical Layer Security And Teaching Methods In Wireless Communications, Zhijian Xie, Christopher Horne Oct 2018

Study Of Physical Layer Security And Teaching Methods In Wireless Communications, Zhijian Xie, Christopher Horne

KSU Proceedings on Cybersecurity Education, Research and Practice

In most wireless channels, the signals propagate in all directions. For the communication between Alice and Bob, an Eavesdropper can receive the signals from both Alice and Bob as far as the Eavesdropper is in the range determined by the transmitting power. Through phased array antenna with beam tracking circuits or cooperative iteration, the signals are confined near the straight line connecting the positions of Alice and Bob, so it will largely reduce the valid placement of an Eavesdropper. Sometimes, this reduction can be prohibitive for Eavesdropper to wiretap the channel since the reduced space can be readily protected. Two …

Towards An Empirical Assessment Of Cybersecurity Readiness And Resilience In Small Businesses, Darrell Eilts, Yair Levy

KSU Proceedings on Cybersecurity Education, Research and Practice

Many small businesses struggle to improve their cybersecurity posture despite the risk to their business. Small businesses lacking adequate protection from cyber threats, or a business continuity strategy to recover from disruptions, have a very high risk of loss due to a cyberattack. These cyberattacks, either deliberate or unintentional, can become costly when a small business is not prepared. This developmental research is focused on the relationship between two constructs that are associated with readiness and resilience of small businesses based on their cybersecurity planning, implementation, as well as response activities. A Cybersecurity Preparedness-Risk Taxonomy (CyPRisT) is proposed using the …

Conventional ultra-high sensitivity detectors in the millimeter-wave range are usually cooled as their own thermal noise at room temperature would mask the weak received radiation. The need for cryogenic systems increases the cost and complexity of the instruments, hindering the development of, among others, airborne and space applications. In this work, the nonlinear parametric upconversion of millimeter-wave radiation to the optical domain inside high-quality (Q) lithium niobate whispering-gallery mode (WGM) resonators is proposed for ultra-low noise detection. We experimentally demonstrate coherent upconversion of millimeter-wave signals to a 1550 nm telecom carrier, with a photon conversion efficiency surpassing the state-of-the-art by …


A New Thickness-Based Accelerated Aging Test Methodology For Resin Materials: Theory And Preliminary Experimental Study, Yanlei Wang, Xue Zhang, Gaochuang Cai, Baolin Wan, Danièle Waldmann, Yuan Qu Oct 2018

A New Thickness-Based Accelerated Aging Test Methodology For Resin Materials: Theory And Preliminary Experimental Study, Yanlei Wang, Xue Zhang, Gaochuang Cai, Baolin Wan, Danièle Waldmann, Yuan Qu

Civil and Environmental Engineering Faculty Research and Publications

This paper proposes a novel accelerated test method based on the thickness of resin materials. This method is to overcome the adverse influence of high temperature on the reliability of experimental results of the accelerated tests widely adopted in the current practice. To verify the proposed thickness-based accelerated method (ThAM), an experimental investigation was conducted focusing on the water absorption and tensile properties of epoxy resin. The results suggest that the existing temperature-based accelerated method (TAM) cannot be applied when the test temperature is high as in this case the degradation mechanism of materials is probably changed. The acceleration factor …

Faculty Publications

We address the design, development, and testing of a pointer/tracker as a probe beam for the purpose of making high-speed, aero-optical measurements of the flow over a scaled beam director turret. The tracker uses retro-reflection of the probe beam off of a Reflexite annulus surrounding the turret. The constraints of the design required a near-total-commercial off the shelf system that could be quickly installed and removed in a rented aircraft. Baseline measurements of environmental vibrations are used to predict pointing performance; mitigation of line-of-sight jitter on the probe beam is achieved through passive isolation and the design of relay optics. …

METHODS: The data of reported TB cases in 340 prefectures from the mainland of China were extracted from the China Information System for Disease Control and Prevention (CISDCP) during January 2005 to December 2015. The Kulldorff's retrospective space-time scan statistics was used to identify the temporal, spatial and spatio-temporal clusters of reported TB in the mainland of China by using the discrete Poisson probability model. Spatio-temporal clusters …


The Use Of Systematic Distractions To Increase Sustained Attention In School-Aged Children With Attention Problems, Emma Larson Oct 2018

The Use Of Systematic Distractions To Increase Sustained Attention In School-Aged Children With Attention Problems, Emma Larson

LSU Master's Theses

With the growing prevalence of Attention Deficit Hyperactivity Disorder (ADHD) in children (DSM-5, 2013), it has been established that the ability of these children to sustain attention is marked with difficulty (Barkley, 2006). Prior research has addressed the need to increase sustained attention in children with ADHD, however, not all of the promising methods take into consideration that children with ADHD have difficulty ignoring distractions (Rapport et al., 2009). This is problematic because the typical classroom environment is filled with distractions. The current study attempted to fill this research gap by training participants to sustain attention while systematically introducing distractions …

Analysis Of Covariance (Ancova) In Randomized Trials: More Precision, Less Conditional Bias, And Valid Confidence Intervals, Without Model Assumptions, Bingkai Wang, Elizabeth Ogburn, Michael Rosenblum Oct 2018

Analysis Of Covariance (Ancova) In Randomized Trials: More Precision, Less Conditional Bias, And Valid Confidence Intervals, Without Model Assumptions, Bingkai Wang, Elizabeth Ogburn, Michael Rosenblum

Johns Hopkins University, Dept. of Biostatistics Working Papers

Covariate adjustment" in the randomized trial context refers to an estimator of the average treatment effect that adjusts for chance imbalances between study arms in baseline variables (called “covariates"). The baseline variables could include, e.g., age, sex, disease severity, and biomarkers. According to two surveys of clinical trial reports, there is confusion about the statistical properties of covariate adjustment. We focus on the ANCOVA estimator, which involves fitting a linear model for the outcome given the treatment arm and baseline variables, and trials with equal probability of assignment to treatment and control. We prove the following new (to the best …
