Raising The Standard Of Maritime Voyage Data Recorder Security, Rory Hopcraft, Harish A Vineetha, Kimberly Tam, Kevin Jones Jan 2023

Raising The Standard Of Maritime Voyage Data Recorder Security, Rory Hopcraft, Harish A Vineetha, Kimberly Tam, Kevin Jones

School of Engineering, Computing and Mathematics

Voyage Data Recorders (VDRs), often referred to as the ‘black boxes’ of the shipping industry, collect and store vital data from key sensors and locations around the ship. This data plays a pivotal role in incident investigation, as was seen in the grounding of the Costa Concordia in 2012, and the sinking of the El Faro in 2015. With such an important role to play, the International Maritime Organization (IMO) has mandated that all SOLAS registered ships carry a VDR, which can demonstrate compliance with internationally agreed standards. Without a VDR compliant with these standards a ship cannot sail. However, …


Development And Prediction Of A Construction Price Index In Egypt, Mohamed Ramadan Jan 2023

Development And Prediction Of A Construction Price Index In Egypt, Mohamed Ramadan

Theses and Dissertations

Cost overrun is one of the most recurring issues in the Egyptian construction industry. The effect is not only on the construction industry ,but also influences the overall economy of a country like Egypt. Therefore, a construction performance index and a construction price index could be an integral indicator of the performance of the industry. These indices can reduce construction companies’ losses and decrease the effect of any sudden economic depression on the construction industry. Several research were conducted to predict construction indices. However, many uncertainties disturb the prediction of these indices. The trend in the prediction models for construction …

E. Coli Catheter-Associated Urinary Tract Infections Are Associated With Distinctive Virulence And Biofilm Gene Determinants, Zongsen Zou, Robert F. Potter, William H. Mccoy, John A. Wildenthal, George L. Katumba, Peter J. Mucha, Gautam Dantas, Jeffrey P. Henderson

2020-Current year OA Pubs

Urinary catheterization facilitates urinary tract colonization by E. coli and increases infection risk. Here, we aimed to identify strain-specific characteristics associated with the transition from colonization to infection in catheterized patients. In a single-site study population, we compared E. coli isolates from patients with catheter-associated asymptomatic bacteriuria (CAASB) to those with catheter-associated urinary tract infection (CAUTI). CAUTI isolates were dominated by a phylotype B2 subclade containing the multidrug-resistant ST131 lineage relative to CAASB isolates, which were phylogenetically more diverse. A distinctive combination of virulence-associated genes was present in the CAUTI-associated B2 subclade. Catheter-associated biofilm formation was widespread among isolates and …

Determining The Proportionality Of Ischemic Stroke Risk Factors To Age, Elizabeth Hunter, John D. Kelleher Jan 2023

Determining The Proportionality Of Ischemic Stroke Risk Factors To Age, Elizabeth Hunter, John D. Kelleher

Articles

While age is an important risk factor, there are some disadvantages to including it in a stroke risk model: age can dominate the risk score and lead to over-or under-predictions in some age groups. There is evidence to suggest that some of these disadvantages are due to the non-proportionality of other risk factors with age, eg, risk factors contribute differently to stroke risk based on an individual’s age. In this paper, we present a framework to test if risk factors are proportional with age. We then apply the framework to a set of risk factors using Framingham heart study data …


Serendipitous Synthesis Of Cross-Conjugated Dienes By Cascade Deconstructive Esterification Of Thiomorpholinone-Tethered Alkenoic Acids, Abdikani Omar Farah, Jorge Garcia, Claire Borg, Timothy K. Beng Jan 2023

Serendipitous Synthesis Of Cross-Conjugated Dienes By Cascade Deconstructive Esterification Of Thiomorpholinone-Tethered Alkenoic Acids, Abdikani Omar Farah, Jorge Garcia, Claire Borg, Timothy K. Beng

Student Published Works

Functionalized 1,3-dienes are ubiquitous structural motifs in biologically pertinent molecules. They are frequently employed as precursors for a broad range of chemical transformations, including Diels-Alder reactions. The stereoselective construction of highly decorated 1,3-dienes therefore represents an important research objective. Medicinal chemists are becoming increasingly interested in synthetic methodologies that not only achieve expedient construction and peripheral editing of heterocycles, but also seek to modify their core framework in order to achieve skeletal remodeling. In a succinct manifestation of this 'scaffold hopping' concept, we herein describe a cascade reaction, which converts thiomorpholinone-tethered alkenoic acids to 1,1-disubstituted amino-1,3-dienes. This domino process involves …

Reducing Tracheal Complications In Endotracheal Intubation Patients Using Automated Cuff Pressure Modulation, Shrihan G. Babu Jan 2023

Reducing Tracheal Complications In Endotracheal Intubation Patients Using Automated Cuff Pressure Modulation, Shrihan G. Babu

Journal of the South Carolina Academy of Science

Endotracheal tube intubation is the third most frequent procedure, performed approximately 13-20 million times yearly in the United States (Mosier et al., 2020). Despite the regularity of the procedure, intubation-related complications such as tracheal injuries, laryngeal injuries, and ventilator-associated pneumonia are ubiquitous due to improper cuff pressure management methods (Ganti et al., 2018). Current techniques, such as the pilot balloon and minimal leak technique, have proven ineffective and inconsistent in managing pressure. As a result, over 71.6% of intubation patients have abnormally high cuff pressures (Ramírez, 2014). Therefore, the purpose of this research was to design an endotracheal tube with …


Linking The Pinware, Baraboo, And Picuris Orogens: Recognition Of A Trans-Laurentian Ca. 1520–1340 Ma Orogenic Belt, Christopher G. Daniel, Aphrodite Indares, L. Gordon Medaris Jr., Ruth Aronoff, David H. Malone, Joshua Schwartz Jan 2023

Linking The Pinware, Baraboo, And Picuris Orogens: Recognition Of A Trans-Laurentian Ca. 1520–1340 Ma Orogenic Belt, Christopher G. Daniel, Aphrodite Indares, L. Gordon Medaris Jr., Ruth Aronoff, David H. Malone, Joshua Schwartz

Faculty Publications - Geography, Geology, and the Environment

It is proposed that the Pinware orogen of eastern Canada, the Baraboo orogen of the midcontinent, and the Picuris orogen of the southwestern United States delineate a previously unrecognized, ~5000-km-long, ca. 1520–1340 Ma trans-Laurentian orogenic belt. All three orogenic provinces are characterized by Mesoproterozoic sedimentation, magmatism, metamorphism, and deformation—the hallmarks of a tectonically active plate margin. Tectonism was diachronous, with the earliest stages beginning ca. 1520 Ma in eastern Canada and ca. 1500 Ma in the southwest United States. Magmatic zircon age distributions are dominated by Mesoproterozoic, unimodal to multimodal age peaks between ca. 1500 and 1340 Ma. The onset …

Needs Assessment And Mentor Program Development For A Midwestern University, Mindy Thompson

DNP and Student Works

An estimated 1.13 million new registered nurses are needed to fill new jobs and replace retiring nurses from 2012-2022. However, the nurse faculty shortage is a primary barrier to expanding the nursing workforce over the next decade (AACN, 2005; AACN, 2015). Nurses moving from the clinical setting to the academic setting need preparation, professional growth, and the development of a social network to make the transition a lasting one (Schoening, 2013). Not only do mentoring relationships improve the work environment, but there is also an indication that it improves organizational commitment by achieving a sense of accomplishment, autonomy in their …


Quantifying The Econometric Loss Of A Cyber-Physical Attack On A Seaport, Kimberly Tam, Barbara Chang, Rory Hopcraft, Kemedi Moara-Nkwe, Kevin Jones Jan 2023

Quantifying The Econometric Loss Of A Cyber-Physical Attack On A Seaport, Kimberly Tam, Barbara Chang, Rory Hopcraft, Kemedi Moara-Nkwe, Kevin Jones

School of Engineering, Computing and Mathematics

Modern Cyber-Physical Systems (CPS) show increasing levels of automation, intelligence, and optimization capabilities. Both creators and adopters of these technologies emphasize the benefits: safety, cost-savings, and efficiencies. Existing literature under-represents the potential risks associated with the adoption of individually complex systems and interconnected Systems-of-Systems (SoS). Research primarily focuses on the potential benefits, and many recent deployments of new technology have received little rigorous scrutiny. The studies that do explore issues, such as cyber-attacks on CPS, often lack an analysis of the potential impact based on the way cyber-physical risks are communicated. Due to high levels of interaction and inter dependencies …


Water Wave Interaction With An Array Of Submerged Circular Plates: Hankel Transform Approach, S. Zheng, H. Liang, S. Michele, D. Greaves Jan 2023

Water Wave Interaction With An Array Of Submerged Circular Plates: Hankel Transform Approach, S. Zheng, H. Liang, S. Michele, D. Greaves

School of Engineering, Computing and Mathematics

In this paper, water wave interaction with an array of thin submerged horizontal circular plates is investigated within the framework of linear potential flow theory. To consider a more general case, the circular plates studied in this paper are not limited to be rigid and impermeable and, instead, they can be perforated and/or elastic. A Hankel transform approach is employed to formulate integral equations in terms of unknown functions related to the jump in velocity potential across each plate. A Galerkin method is adopted to the solution of these integral equations, and the velocity potential jump across the plate is …

Defining Interim Storage Of Nuclear Waste, Max Johnson Jan 2023

Defining Interim Storage Of Nuclear Waste, Max Johnson

Northwestern University Law Review

Nuclear power may be humanity’s best hope to curb climate-altering greenhouse gas emissions. But public fear of its dangers, including the toxicity of nuclear waste, undermines its expansion. To provide for more effective waste disposal, in 2021 and 2022 the Nuclear Regulatory Commission (NRC) recommended licensing two privately-owned nuclear waste storage facilities—called Consolidated Interim Storage Facilities (CISFs)—to be built in New Mexico and in Texas. Both states vehemently oppose the construction and operation of these facilities: legislators in both states have proposed state laws opposing them, and both states have sued the NRC challenging the legality of the facilities’ licensure. …

Secap Switch—Defeating Topology Poisoning Attacks Using P4 Data Planes, Dylan Smyth, Sandra Scott-Hayward, Victor Cionca, Sean Mcsweeney, Donna O'Shea Jan 2023

Secap Switch—Defeating Topology Poisoning Attacks Using P4 Data Planes, Dylan Smyth, Sandra Scott-Hayward, Victor Cionca, Sean Mcsweeney, Donna O'Shea

Department of Computer Science Publications

Programmable networking is evolving from programmable control plane solutions such as OpenFlow-based software-defined networking (SDN) to programmable data planes such as P4-based SDN. To support the functionality of the SDN, the correct view of the network topology is required. However, multiple attacks aimed at topology poisoning have been demonstrated in SDNs. While several controller-centralised security solutions have been proposed to defeat topology poisoning attacks, some attacks e.g., the Data Plane ARP Cache Poisoning Attack and the relay-type Link Fabrication Attack are difficult to detect using a fully centralised security solution. In this paper, we present the Security-Aware Programmable (SECAP) Switch—a …
