Faculty Publications

Studies have shown that the elderly are at a higher risk of developing malnutrition due to physiological and pathological changes. Several studies have confirmed that older South Africans have insufficient dietary diversity, resulting in nutritional deficiencies. Furthermore, poor and uninformed dietary choices are associated with the development of several diseases and increased mortality. Following the Elderly Food Based Dietary Guidelines (EFBDGs) related to promoting elderly health could ensure that the elderly have an adequate intake of nutritious foods. This paper provides an overview of six FBDGs relating to promoting health and is based on the South African Food Based Dietary …

Solopreneur Digital Ecosystems: Genesis, Lineage And Preliminary Categorization, Gabriele Piccoli, Biagio Palese, Joaquin Rodriguez

Faculty Publications

This paper traces the genesis and lineage of solopreneur digital ecosystems. These ecosystems, fostered by a digital environment that is infrastructural, combinatorial and servitized, are enabling the rise to prominence of the solopreneur. We theorize solopreneur digital ecosystems as the latest incarnation of systems beyond firm control, with digital platforms and digital marketplaces as their principal enablers. In an effort to compare them from the perspective of the solopreneur, we categorize solopreneur digital ecosystems on three dimensions: algorithmic control, commoditization, and lock-in. Our work contributes a framework that solopreneurs can use to identify ecosystems in which they can optimally invest …

Virtual Reality As A Versatile Tool For Research, Dissemination And Mediation In The Humanities, Paul François, Jeffrey Leichman, Florent Laroche, Françoise Rubellin

Faculty Publications

The VESPACE project aims to revive an evening of theatre at the Foire Saint-Germain in Paris in the 18th century, by recreating spaces, atmospheres and theatrical entertainment in virtual reality. The venues of this fair have disappeared without leaving any archaeological traces, so their digital reconstruction requires fusing many different sources, including the expertise of historians, as well as of historians of theatre and literature. In this article, we present how we have used video game creation tools to enable the use of virtual reality in three key research stages in the human sciences, and particularly, in history or archaeology: …

Fear Of Zika: Information Seeking As Cause And Consequence, James Price Dillard, Ruobing Li, Chun Yang

Faculty Publications

This study examined the relationship between information seeking and fear during the Zika-induced global health crisis. A longitudinal survey of women in the Southern U.S. (N = 306) was conducted in 2016, beginning just days after the World Health Organization declared Zika a global crisis. The data showed that time 1 fear stimulated information seeking at time 2 and that time 2 information seeking caused fear at time 3. This pattern held regardless of whether participants were pregnant or planning to become pregnant (high personal relevance) versus neither (low personal relevance). The findings are at odds with most theories of …

Sailing To Freedom: Maritime Dimensions Of The Underground Railroad, Kate Clifford Larson

Civil War Book Review

Editor Timothy Walker and the chapters’ authors challenge the “20^th century fakelore featuring the use of quilt codes, lawn jockeys and other physical devices as signs and signals.” What their collection shows is “that escape by water, through a vast network of maritime links, was far more common,” as escapees often hid in plain sight, posing as dockworkers, and seamen, on their way to freedom.

Black Freedom In The Age Of Slavery: Race, Status, And Identity In The Urban Americas, Takkara Brunson

Civil War Book Review

Marks shows that when Black people attempted to better their lives, they challenged extant racialized practices and the ideology of white supremacy that dominated both Charleston, South Carolina and Cartahena, Colombia. Still, white leaders in both cities approached Black freedom in distinct ways. Marks’s work opens the door for further exploration, which is a testament “to the successes of Marks’s comparative approach for examining local histories of race and slavery.”

Marine Vehicles Localization Using Grid Cells For Path Integration, Ignacio Carlucho, Manuel F. Bailey, Mariano De Paula, Corina Barbalata

Faculty Publications

Autonomous Underwater Vehicles (AUVs) are platforms used for research and exploration of marine environments. However, these types of vehicles face many challenges that hinder their widespread use in the industry. One of the main limitations is obtaining accurate position estimation, due to the lack of GPS signal underwater. This estimation is usually done with Kalman filters. However, new developments in the neuroscience field have shed light on the mechanisms by which mammals are able to obtain a reliable estimation of their current position based on external and internal motion cues. A new type of neuron, called Grid cells, has been …

From Market-Ready Rovs To Low-Cost Auvs, Jonatan Scharff Willners, Ignacio Carlucho, Sean Katagiri, Chandler Lemoine, Joshua Roe, Dylan Stephens, Tomasz Luczynski, Shida Xu, Yaniel Carreno, Eric Pairet, Corina Barbalata, Yvan Petillot, Sen Wang

Faculty Publications

Autonomous Underwater Vehicles (AUVs) are becoming increasingly important for different types of industrial applications. The generally high cost of AUVs restricts the access to them and therefore advances in research and technological development. However, recent advances have led to lower cost commercially available Remotely Operated Vehicles (ROVs), which present a platform that can be enhanced to enable a high degree of autonomy, similar to that of a high-end AUV. In this article, we present how a low-cost commercial-off-the-shelf ROV can be used as a foundation for developing versatile and affordable AUVs. We introduce the required hardware modifications to obtain a …

Event-Triggered Control For Systems With State Delays Using A Positive Systems Approach, Frederic Mazenc, Michael Malisoff, Corina Barbalata, Zhong Ping Jiang

Faculty Publications

We provide a new positive system approach to event-triggered feedback control of linear systems with state delays. We use an interval observer method and linear Lyapunov functions to prove global exponential stability of the closed loop systems. Our two examples illustrate the usefulness of our method for counteracting the effects of potentially destabilizing state delays.

Intelligent Spectrum Management And Trajectory Design For Uav-Assisted Cognitive Ambient Backscatter Networks, Jiazhou Liu, Sa Xiao, Huayan Guo, Xiangwei Zhou, Shixin He

Faculty Publications

In this paper, we consider a novel Internet of Things (IoT) system in smart city called unmanned aerial vehicle- (UAV-) assisted cognitive backscatter network, where a UAV is employed as both a relay and a radio frequency source to help the data transmission between ground IoT backscatter devices (BDs) and a remote data center (DC). However, since the IoT applications are usually not assigned dedicated spectrum resource in smart cities, these data transmissions from BDs to the DC should share the licensed spectrum of cellular users (CUs). Therefore, we aim to maximize the minimum uplink throughput among all BDs while …

Octo-Tiger's New Hydro Module And Performance Using Hpx+Cuda On Ornl's Summit, Patrick Diehl, Gregor Daiß, Dominic Marcello, Kevin Huck, Sagiv Shiber, Hartmut Kaiser, Juhan Frank, Geoffrey C. Clayton, Dirk Pfluger

Faculty Publications

Octo-Tiger is a code for modeling three-dimensional self-gravitating astrophysical fluids. It was particularly designed for the study of dynamical mass transfer between interacting binary stars. Octo-Tiger is parallelized for distributed systems using the asynchronous many-task runtime system, the C++ standard library for parallelism and concurrency (HPX) and utilizes CUDA for its gravity solver. Recently, we have remodeled OctoTiger's hydro solver to use a three-dimensional reconstruction scheme. In addition, we have ported the hydro solver to GPU using CUDA kernels. We present scaling results for the new hydro kernels on ORNL's Summit machine using a Sedov-Taylor blast wave problem. We also …

Well-Scale Multiphase Flow Characterization And Validation Using Distributed Fiber-Optic Sensors For Gas Kick Monitoring, Jyotsna Sharma, Otto L.A. Santos, Giuseppe Feo, Oloruntoba Ogunsanwo, Wesley Williams

Faculty Publications

Early detection of a gas kick is crucial for preventing uncontrolled blowout that could cause loss of life, loss of assets, and environmental damage. Multiphase flow experiments conducted in this research demonstrate the capability of downhole fiber optic sensors to detect a potential gas influx in real-time in a 5000 ft deep wellbore. Gas rise velocities estimated independently using fiber optic distributed acoustic sensor (DAS), distributed temperature sensor (DTS), downhole gauges, surface measurements, and multiphase flow correlations show good agreement in each case, demonstrating reliability in the assessment. Real-time data visualization was implemented on a secure cloud-based platform to improve …

Student Perceptions Of Rules For Classroom Interaction, Hanson Paul Leblanc Iii

LSU Master's Theses

ABSTRACT

Burgoon’s expectancy violation model posits that nonverbal rule violations will be evaluated according to the perceptions toward the violator and the behavior itself. However, the violator may have perceptions regarding the appropriateness of the rule. This study measured the perceptions of high school students regarding the rules for classroom interaction. It is believed that the rules for classroom interaction are rules which have been learned through the process of socialization and enculturation into the classroom setting throughout students’ careers. These rules should be well known by all students by the time they reach tenth grade, the grade being investigated. …
