Risk Analysis Of Job Stress Among Balinese Crew Of Cruise Ships, Made Adhyatma Prawira Natha Kusuma, Indri Hapsari Hapsari Susilowati

National Journal of Occupational Health and Safety

Job stress can appear in all fields of work. Job stress not only occurs from the environment at work but also can be caused by the psychological condition of the workers. Working on a cruise ship demands higher patience to serve the guests in various activities and handle complaints. Moreover, work on cruise ships causes the workers separated from their families for a long time period, which can increase their mental pressure. The aim of this research is to describe the job stress of workers at a cruise ship. This research was conducted in January-June 2017. In an attempt to …

Conditional Generative Adversarial Network Demosaicing Strategy For Division Of Focal Plane Polarimeters, Garrett Sargent, Bradley M. Ratliff, Vijayan K. Asari

Electrical and Computer Engineering Faculty Publications

Division of focal plane (DoFP), or integrated microgrid polarimeters, typically consist of a 2 × 2 mosaic of linear polarization filters overlaid upon a focal plane array sensor and obtain temporally synchronized polarized intensity measurements across a scene, similar in concept to a Bayer color filter array camera. However, the resulting estimated polarimetric images suffer a loss in resolution and can be plagued by aliasing due to the spatially-modulated microgrid measurement strategy. Demosaicing strategies have been proposed that attempt to minimize these effects, but result in some level of residual artifacts. In this work we propose a conditional generative adversarial …

Pandemic Vibrio Cholerae Shuts Down Site-Specific Recombination To Retain An Interbacterial Defence Mechanism, Francis J. Santoriello, Lina Michel, Daniel Unterweger, Stefan Pukatzki

Publications and Research

Vibrio cholerae is an aquatic microbe that can be divided into three subtypes: harmless environmental strains, localised pathogenic strains, and pandemic strains causing global cholera outbreaks. Each type has a contact-dependent type VI secretion system (T6SS) that kills neighbouring competitors by translocating unique toxic effector proteins. Pandemic isolates possess identical effectors, indicating that T6SS effectors may affect pandemicity. Here, we show that one of the T6SS gene clusters (Aux3) exists in two states: a mobile, prophage-like element in a small subset of environmental strains, and a truncated Aux3 unique to and conserved in pandemic isolates. Environmental Aux3 can be readily …

Varying The Aspect Ratio Of Toroidal Ion Traps: Implications For Design, Performance, And Miniaturization, Praneeth Madushan Hettikankanange

Theses and Dissertations

A large aspect ratio leads to higher ion capacity in miniaturized ion trap mass spectrometers. The aspect ratio (AR) of an ion trap represents the ratio between an extended trapping dimension and the characteristic trapping dimension. In contrast to linear and rectilinear traps, changing the AR of a toroidal ion trap (TorIT) results in changes to the degree of curvature and shape of the trapping potential, and hence, on performance as a mass analyzer. SIMION simulations show that higher-order terms in the trapping potential vary strongly for small and moderate AR values (below ~10), with the effects asymptotically flattening for …

Crime Prediction With Historical Crime And Movement Data Of Potential Offenders Using A Spatio-Temporal Cokriging Method, Hongjie Yu, Lin Liu, Bo Yang, Minxuan Lan

Faculty Research, Scholarly, and Creative Activity

Crime prediction using machine learning and data fusion assimilation has become a hot topic. Most of the models rely on historical crime data and related environment variables. The activity of potential offenders affects the crime patterns, but the data with fine resolution have not been applied in the crime prediction. The goal of this study is to test the effect of the activity of potential offenders in the crime prediction by combining this data in the prediction models and assessing the prediction accuracies. This study uses the movement data of past offenders collected in routine police stop-and-question operations to infer …

Monomer Selection For In Situ Polymerization Infusion Manufacture Of Natural-Fiber Reinforced Thermoplastic-Matrix Marine Composites, Yang Qin, John Summerscales, Jasper Graham-Jones, Maozhou Meng, Richard Pemberton

School of Engineering, Computing and Mathematics

Awareness of environmental issues has led to increasing interest from composite researchers in using “greener” materials to replace synthetic fiber reinforcements and petrochemical polymer matrices. Natural fiber bio-based thermoplastic composites could be an appropriate choice with advantages including reducing environmental impacts, using renewable resources and being recyclable. The choice of polymer matrix will significantly affect the cost, manufacturing process, mechanical properties and durability of the composite system. The criteria for appropriate monomers are based on the processing temperature and viscosity, polymer mechanical properties, recyclability, etc. This review considers the selection of thermoplastic monomers suitable for in situ polymerization during resin, …

Development Of A Flow Control Valve Using Magnetorheological Fluid, Scott A. Bell

Theses

This research aims to develop and characterize the behavior of a newly ideated valve that actuates based on magnetorheological fluid (MRF) in a volume surrounding a flexible thin-walled tube. This valve had the goal of reducing the obstruction and complexities within the pathway of fluid flow when compared to a commercial valve. A decrease in the obstructions would increase the efficiency of the valve. An iterative design process was employed to develop this valve through multiple preliminary concepts and two physical iterations. The first iteration presented multiple areas for improvement, which led to the second design. The second design was …

Secure Outsourced Computation On Encrypted Data, Asma Aloufi

Theses

Homomorphic encryption (HE) is a promising cryptographic technique that supports computations on encrypted data without requiring decryption first. This ability allows sensitive data, such as genomic, financial, or location data, to be outsourced for evaluation in a resourceful third-party such as the cloud without compromising data privacy. Basic homomorphic primitives support addition and multiplication on ciphertexts. These primitives can be utilized to represent essential computations, such as logic gates, which subsequently can support more complex functions. We propose the construction of efficient cryptographic protocols as building blocks (e.g., equality, comparison, and counting) that are commonly used in data analytics and …

Food System Resilience In Nigeria: Farmers Perspective, Azariah Lawal

School of Natural Resources: Dissertations, Theses, and Student Research

Disturbances are inherent in every socio-ecological system (SES). However, the spate and scope of upheavals in contemporary SES has increased dramatically in recent years. Agricultural systems are perhaps the most impacted when disasters occur because different aspects of agricultural production are directly affected. The burgeoning farmers-Fulani herdsmen conflict in West Africa is a manifestation of these challenges. When faced with events like these, contemporary food systems are faced with two options: collapse or transform. It is essential to have resilient agricultural systems because these systems lie at the nexus of resolving emerging global issues.

Nigeria is an important country in …

Public Health Sciences Faculty Publications

Background Carbon nanotubes and nanofibers (CNT/F) have known toxicity but simultaneous comparative studies of the broad material class, especially those with a larger diameter, with computational analyses linking toxicity to their fundamental material characteristics was lacking. It was unclear if all CNT/F confer similar toxicity, in particular, genotoxicity. Nine CNT/F (MW #1-7 and CNF #1-2), commonly found in exposure assessment studies of U.S. facilities, were evaluated with reported diameters ranging from 6 to 150 nm. All materials were extensively characterized to include distributions of physical dimensions and prevalence of bundled agglomerates. Human bronchial epithelial cells were exposed to the nine …

Feedback Induced Magnetic Phases In Binary Bose-Einstein Condensates, Hilary M. Hurst, Shangjie Guo, I. B. Spielman

Faculty Research, Scholarly, and Creative Activity

Weak measurement in tandem with real-time feedback control is a new route toward engineering novel non-equilibrium quantum matter. Here we develop a theoretical toolbox for quantum feedback control of multicomponent Bose-Einstein condensates (BECs) using backaction-limited weak measurements in conjunction with spatially resolved feedback. Feedback in the form of a single-particle potential can introduce effective interactions that enter into the stochastic equation governing system dynamics. The effective interactions are tunable and can be made analogous to Feshbach resonances -- spin-independent and spin-dependent -- but without changing atomic scattering parameters. Feedback cooling prevents runaway heating due to measurement backaction and we present …

Impact Of Network And Host Characteristics On The Keystroke Pattern In Remote Desktop Sessions, I Kuzminykh, B Ghita, A Silonosov

School of Engineering, Computing and Mathematics

Authentication based on keystroke dynamics is a convenient biometric approach, easy in use, transparent, and cheap as it does not require a dedicated sensor. Keystroke authentication, as part of multi factor authentication, can be used in remote display access to guarantee the security of use of remote connectivity systems during the access control phase or throughout the session. This paper investigates how network conditions and additional host interaction may impact the behavioural pattern of keystrokes when used in a remote desktop application scenario. We focus on the timing of adjacent keys and investigate this impact by calculating the variations of …

Computer Vision For Recycling, Pratima Kandel

Departmental Honors & Graduate Capstone Projects

Americans recycle 32.1 percent of all the waste they create, as confirmed by the latest report from the Environmental Protection Agency. However, the underlying issue that remains is that most Americans are not equipped with the knowledge of the correct methods of recycling – and the deficiency of that knowledge is the greatest quandary to ensuring that the country is “green” and environment friendly. A survey of two thousand American citizens revealed that 62 percent of them worry that this inadequate knowledge is causing them to recycle incorrectly. The aim of this research is to develop an Android App, where …

Segment And Intersection Crash Analysis Methodologies For Utah Highways, Camille Cherie Lunt

Theses and Dissertations

This research focuses on the Crash Analysis Methodology for Segments (CAMS) which provides a way for engineers at the Utah Department of Transportation (UDOT) to prioritize safety improvements on state-owned roadways. Unlike the Utah crash analysis methodologies that come before it, the CAMS focuses exclusively on segment-related crashes. The benefits of such an analysis can be found in identifying locations that have safety concerns unbiased from intersections and their related crashes. The CAMS uses UDOT data to create a spreadsheet of roadway segments and their associated crashes. Each segment is homogeneous with respect to five variables: Annual Average Daily Traffic …

I have since discovered that my success and progress in life depend on my willingness to harness my greatness. During the process of writing this book, I discovered myself. I left Nigeria in my late teens, and I have been abroad ever since. …

Covid-19, Labor Demand, And Government Responses: Evidence From Job Posting Data, Xiaobing Shuai, Christine Chmura, James Stinchcomb

School of Professional and Continuing Studies Faculty Publications

Using high-frequency job advertisement data, this paper evaluates dynamics among COVID-19, labor market, and government policies. We find that COVID-19 has caused a significant decline in labor demand, by as much as 30%, measured by the number of job advertisements. But the pandemic did not result in noticeable changes in advertised wages. Regarding the roles of government policies, the study finds that the “stay-at-home” measures implemented by states appeared to suppress labor demand. The Paycheck Protection Program (PPP) program helps to stabilize the advertised wages, but also suppresses labor demand. Finally, the pandemic may increase labor demand for certain healthcare-related …
