Ears-Dm: Efficient Auto Correction Retrieval Scheme For Data Management In Edge Computing, Kai Fan, Jie Yin, Kuan Zhang, Hui Li, Yintang Wang

Department of Electrical and Computer Engineering: Faculty Publications

Edge computing is an extension of cloud computing that enables messages to be acquired and processed at low cost. Many terminal devices are being deployed in the edge network to sense and deal with the massive data. By migrating part of the computing tasks from the original cloud computing model to the edge device, the message is running on computing resources close to the data source. The edge computing model can effectively reduce the pressure on the cloud computing center and lower the network bandwidth consumption. However, the security and privacy issues in edge computing are worth noting. In this …

Optimal Computational Power Allocation In Multi-Access Mobile Edge Computing For Blockchain, Yuan Wu, Xiangxu Chen, Jiajun Shi, Kejie Ni, Liping Qian, Liang Huang, Kuan Zhang

Department of Electrical and Computer Engineering: Faculty Publications

Blockchain has emerged as a decentralized and trustable ledger for recording and storing digital transactions. The mining process of Blockchain, however, incurs a heavy computational workload for miners to solve the proof-of-work puzzle (i.e., a series of the hashing computation), which is prohibitive from the perspective of the mobile terminals (MTs). The advanced multi-access mobile edge computing (MEC), which enables the MTs to offload part of the computational workloads (for solving the proof-of-work) to the nearby edge-servers (ESs), provides a promising approach to address this issue. By offloading the computational workloads via multi-access MEC, the MTs can effectively increase their …

Metasurface Base On Uneven Layered Fractal Elements For Ultra-Wideband Rcs Reduction, Jianxun Su, Yueyang Cui, Zengrui Li, Yaoqing (Lamar) Yang, Yongxing Che, Hongcheng Yin

Department of Electrical and Computer Engineering: Faculty Publications

A novel metasurface based on uneven layered fractal elements is designed and fabricated for ultra-wideband radar cross section (RCS) reduction in this paper. The proposed metasurface consists of two fractal subwavelength elements with different layer thickness. The reflection phase difference of 180^◦ (±37^◦) between two unit cells covers an ultra-wide frequency range. Ultra-wideband RCS reduction results from the phase cancellation between two local waves produced by these two unit cells. The diffuse scattering of electromagnetic (EM) waves is caused by the randomized phase distribution, leading to a low monostatic and bistatic RCS simultaneously. This metasurface can achieve …

Information Theory And Cognition: A Review, Khalid Sayood

Department of Electrical and Computer Engineering: Faculty Publications

We examine how information theory has been used to study cognition over the last seven decades. After an initial burst of activity in the 1950s, the backlash that followed stopped most work in this area. The last couple of decades has seen both a revival of interest, and a more firmly grounded, experimentally justified use of information theory. We can view cognition as the process of transforming perceptions into information—where we use information in the colloquial sense of the word. This last clarification is one of the problems we run into when trying to use information theoretic principles to understand …

Free To Hate: Can We Justify Curbing Hateful Speech?, Logan Drake

UReCA: The NCHC Journal of Undergraduate Research and Creative Activity

Hate speech and free speech, and the relationship between the two, have been prominent in the news lately, especially regarding speech on college campuses. It seems to me, however, that the debate usually lacks nuance. One side is portrayed as being free speech absolutists, while the other is seen as creating rules and restrictions that send us down a road towards totalitarianism and tyranny. In reality, however, very few people actually desire either of these extremes. No one wants tyrannical totalitarianism, and nearly everyone will admit that there needs to be, at the very least, restrictions on who can speak …

A Comparison Of Corrosion Potential, Installation, Maintenance, And Anti-Microbial Efficacy: Copper Combined With A Polymer Matrix Or Stainless Steel For Use In A Hospital Setting, Barika Mirza

UReCA: The NCHC Journal of Undergraduate Research and Creative Activity

According to Boev and Kiss in their article, “Hospital-Acquired Infections,” hospital-acquired infections (HAIs), also known as nosocomial infections, are currently the leading cause of deaths and disability in hospitalized patients (2017, p. 51), so they cost both patients and hospitals a lot of money. As of right now, QualityNet reports on their “Scoring Methodology” page that Obamacare’s Hospital-Acquired Condition (HAC) Reduction Program requires for hospitals with high cases of HACs to be subject to a reduction of Medicare payments (n.d.). The World Health Organization explains in Prevention of hospital-acquired infections: A practical guide, 2nd edition that HAIs can be acquired …

Closet Land: Combining Theatre And Film For A Psychological Thrill, Ashley Snead, Janet Hayatshahi

UReCA: The NCHC Journal of Undergraduate Research and Creative Activity

This paper reflects an intense study of the benefits of how film can be integrated into theatrical live performance. Traditionally, live theatrical performance has used three-dimensional bodies in space to help in its storytelling. This research seeks to find ways in which live performance can be complimented through the use of multimedia components. Based on an analysis of the script Closet Land, by Radha Bharadwaj, this research highlights moments from the text by showing how the use of video and still images displayed through projectors in the live performance enhances the storytelling and gives broader depth to the characters’ subconscious …

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Mycobacterium avium subsp. paratuberculosis is responsible for paratuberculosis in animals. This disease, leading to an inflammation of the gastrointestinal tract, has a high impact on animal health and an important economic burden. The environmental life cycle of M. avium subsp. paratuberculosis is poorly understood and several studies suggest that free-living amoebae (FLA) might be a potential environmental host. FLA are protozoa found in water and soil that are described as reservoirs of pathogenic and non-pathogenic bacteria in the environment. Indeed, bacteria able to survive within these amoebae would survive phagocytosis from immune cells. In this study, we assessed the in …

Emergency Management In Community Colleges: Why Colleges Need To Be Prepared, Dave Dibelka

Department of Educational Administration: Dissertations, Theses, and Student Research

This practice brief provides community college leaders with recommendations for preparing for emergencies that could occur on their campuses. When issues occur on college campuses that have an impact on day-to-day operations, administrators need to be prepared to ensure that their students, faculty, and staff have the knowledge of what to do before and after these situations occur. Also, these issues can bring increased media attention and, if the incident is not handled properly, it can cause serious harm to the institution's reputation. Having plans and teams in place prior to an incident will benefit not only the institution but …

International Students In Their Own Country: Motivation Of Vietnamese Graduate Students To Attend A Collaborative Transnational University, Christina W. Yao, Crystal E. Garcia

Objective: Beyond understanding whether first-year student success interventions in community colleges are effective—for which there is mixed evidence in the literature—this study’s purpose was to uncover how they work to realize observed outcomes, including at times unanticipated undesirable outcomes.

Method: This qualitative multiple case study used cultural historical activity theory (CHAT) to unpack interactions and tensions among programmatic-level features and individual-level experiences and actions. We conducted classroom observation, document analysis, and interviews with instructors and students in four student success courses across diverse contexts.

Results: Regardless of particular designs and course emphases, we found in all cases a blurring of …

The Secant Rate Of Corrosion: Correlating Observations Of The Uss Arizona Submerged In Pearl Harbor, Donald L. Johnson, Robert J. Deangelis, Dana J. Medlin, Jon E. Johnson, James D. Carr, David L. Conlin

Department of Chemistry: Faculty Publications

Contrary to previous linear projections of steel corrosion in seawater, analysis of an inert marker embedded in USS Arizona concretion since the 7 December 1941 attack on Pearl Harbor reveals evidence that the effective corrosion rate decreases with time. The secant rate of corrosion, or SRC correlation, derived from this discovery could have a significant impact on failure analysis investigations for concreted shipwrecks or underwater structures. The correlation yields a lower rate of metal thinning than predicted. Development of the correlation is described.

Noise Induced Hearing Loss Accountability On Jobsites Within The Construction Industry, Joseph O. Lamphere

Construction Management

Noise induced hearing loss is a major issue on jobsites within the construction industry. Every day workers are exposed to hazardous levels of noise, but they are not being properly managed to mitigate this issue. Workers have misconceptions about the topic, but more surprisingly are sometimes indifferent to the effects; believing hearing loss is inevitable, or it can be cured with a hearing aide. Construction has inherent dangers that workers have to deal with every day. Hearing loss might not be on the top of their lists, but the effects are permanent, and they cannot be cured with a hearing …

Modeling Canopy Effect In The Great Lakes Cladophora Model, Ankita Bakshi

Dissertations, Master's Theses and Master's Reports

Cladophora glomerata is a filamentous green alga native to the Great Lakes. However, its nuisance growth in phosphorus rich waters negatively affects the lakes’ aesthetic and water quality. The Great Lakes Cladophora Model (GLCM) v1, developed in 1982, was the first mechanistic model to simulate Cladophora growth basing phosphorus availability and environmental conditions followed by Cladophora Growth Model and GLCM v2. In this study, the light and temperature mediation factors for Cladophora net growth are revised as a necessary step prior to the development of a self-shading algorithm. The concept of a fixed-value, maximum achievable biomass (carrying capacity) employed in …

Power Flow Control In Hybrid Ac/Dc Microgrids, Ronald C. Matthews

Dissertations, Master's Theses and Master's Reports

Microgrid structures allow for more efficient utilization of renewable resources as well as autonomous operation. Ideally, a centralized controller would be available to allow for an optimizer to take all components into account so that they may collaboratively work towards a shared goal. To this end, a centralized optimization method was developed called the squared slack interior point method. The novelty of this method is that it incorporates the fraction to bound rule to alleviate the known ill-conditioning introduced by utilizing squared slack variables to handle inequality constraints. In addition, this method also allows for inequality constraint violations to be …

Buying Unicorns: The Impact Of Consumer-To-Consumer Branded Buy/Sell/Trade Communities On Traditional Retail Buying Behavior, Catherine Armstrong Soule, Sara Hanson

Marketing Faculty Publications

Branded buy/sell/trade (BBST) is a consumer-to-consumer (C2C) selling phenomenon that is both massive in scale and meaningful in its impact on consumer behavior and the traditional retailing landscape. Consumers buy, sell, and trade one focal brand’s products in these social media-hosted, consumer-initiated communities. This article introduces the phenomenon, differentiates it from other forms of C2C exchange, and explores relationships between members and the brand. Although brands may view these activities as a potential threat to retail sales, the effects are more complex and paradoxical. The authors present data collected from Facebook, in-depth interviews, and a survey. Findings suggest that buyer-sellers …

Friends With Benefits: Social Coupons As A Strategy To Enhance Customers’ Social Empowerment, Sara Hanson, Hong Yuan

Marketing Faculty Publications

Businesses often seek to leverage customers’ social networks to acquire new customers and stimulate word-of-mouth recommendations. While customers make brand recommendations for various reasons (e.g., incentives, reputation enhancement), they are also motivated by a desire for social empowerment—to feel an impact on others. In several multi-method studies, we show that facilitating sharing of social coupons (i.e., coupon sets that include one for self-use and one to be shared) is a unique marketing strategy that facilitates social empowerment. Firms benefit from social coupons because customers who share spend more and report greater purchase intentions than those who do not. Furthermore, we …
