Enabling Slotted Aloha-Noma For Massive Machine-To-Machine (M2m) Communication In Internet Of Thing (Iot) Networks, Richard D. Gitlin, Mohamed H. Elkourdi, Asim M. Mazin

USF Patents

Slotted Aloha-NOMA (SAN) protocol is an uncoordinated, non-orthogonal, random access protocol that exploits the simplicity of SA (Slotted Aloha) and the superior throughput of non-orthogonal multiple access (NOMA) and its ability to resolve collisions via use of successive interference cancellation (SIC) receiver. In SAN protocol, the SIC receiver at the IoT gateway adaptively learns the number of active devices (which is not known a priori) using multiple hypothesis testing in order to successfully distinguish between signals transmitted from different IoT devices.

System And Method Of Audit Log Protection, Attila Altay Yavuz

USF Patents

A computer data security system, useful in protecting audit logs, includes symmetric key based techniques, requires only a small-constant number of cryptographic hash operations at the signer side sending a prospective audit log or other computer record data to a primary repository to achieve forward-secure and append-only authentication. The verification is performed by independent parties sharing parts of the symmetric key, wherein the presence of single honest party among all verifier parties ensures a conditional non-repudiation. It also ensures that an active adversary cannot generate authentication tags on behalf of the signer, unless it compromises all verification parties.

Elemental Climate Disaster Texts And Queer Ecological Temporality, Laura Mattson

USF Tampa Graduate Theses and Dissertations

This thesis approaches climate disaster texts as an opportunity to challenge constructions of the body, space, and time. Developed from embodied experiential knowledge about hurricanes, my work will explore how climate disasters can teach us to reimagine human-nature relationships. In my two analysis chapters, I use critical textual analysis and autoethnography to challenge particular representations of the human-nature relationship as a binary between nature and culture. By intervening in the nature-culture binary, I theorize queer ecological temporality as an opportunity to reveal and challenge constructions of nature and time. Working at the intersections of queer and ecocritical theory, this thesis …

Development And Assessment Of A Continuing Education Unit In Quantitative Literacy For High School Stem Teachers, Craig P. Mcclure

Numeracy

Influencing the teaching of quantitative literacy at all levels of education can be difficult due to the many demands placed on educators. In a continuing education course, public high school science teachers participated in a pilot study of a program on quantitative literacy, involving defining quantitative literacy, how it is beneficial to students, examples of quantitative literacy education, and how it may be supported in the science classroom. Surveys administered before and after the unit indicate an improvement in the teachers’ understanding of quantitative literacy, and a follow-up survey indicates that the unit impacted classroom practice. Results support the conclusion …

Value Innovation Activities In The Wireless Telecommunications Service Sector: A Case Study Of The Malaysian Market, Mohammed A. Hajar, Daing Nasir Ibrahim, Mohd Ridzuan Darun, Mohammed A. Al-Sharafi

Journal of Global Business Insights

Innovation has become an important source of growth and survival for the telecom industry, especially with the highly competitive, dynamic business environment of this sector. The telecom market attributes of liberalization, privatization and globalization result in fierce competition, which aggravates telecom firms’ challenges to expand their market share, and hence, increase customer base, sales volume, and ultimately profit. A new strategy to succeed is innovation differentiation, which leads to breaking out the competition and creating uncongested market space. The aim of this paper is to highlight the logic of value innovation in the wireless telecom sector. A qualitative research approach …

Algorithms To Profile Driver Behavior From Zero-Permission Embedded Sensors, Bharti Goel

USF Tampa Graduate Theses and Dissertations

In this dissertation, we design algorithms to profile driver behavior from zero-permission sensors embedded in modern smartphones and wearables. These sensors are typically the accelerometer, gyroscope, magnetometer, pressure sensor and a few more than are now available in most modern smartphones and wearables. In order to profile driving behavior, we devised algorithms for detecting distraction while driving due to the use of modern-day smartphones (e.g., calling, texting and reading while driving) in real-time.

To do so, we conduct an experiment with 16 subjects on a realistic driving simulator, where each subject, where each subject carries a smartphone and a wearable …

How Audiovisual Composition Reveals Gendered Limitations And Possibilities In Lady Bird In The Wake Of #Metoo, Chandler Micah Reeder

USF Tampa Graduate Theses and Dissertations

This thesis focuses on the film Lady Bird and the historical coincidence of its release one month after the online movement #MeToo began. By giving frame and sound equal importance in my analysis of the film, rather than opposing these elements, I emphasize audiovisual composition and reveal the mutual dependence within what are considered traditional divisions of theory in cinema. These oppositions relate to control and escape, as they are portrayed through the mother and daughter characters, Marion and Lady Bird, as well as through image and sonic elements. My work demonstrates how the audiovisual composition of the film mediates …

Legitimizing Violence: Functional Similarities Of The Religious And The Secular Violence, Tahir Topal

USF Tampa Graduate Theses and Dissertations

As a consequence of the separation between religion and politics, known as secularism, the discussion about violence has also been divided into two main categories –Religious Violence and Non-Religious Violence– in the modern Western academia. The tendency of the leading scholarly work in the discourse of "religious violence" is that "religion" is inclined to be violent more than secular institutions for several reasons. Therefore, the state's violence, as being secular, steps in to bring peace. And the foundational cause of the theories relies heavily on the essential differences of "religion" and the secular. With counter-arguments, William T. Cavanaugh and Talal …

Global Karst Springs Hydrograph Dataset For Research And Management Of The World’S Fastest-Flowing Groundwater, Tunde Olarinoye, Tom Gleeson, Vera Marx

KIP Articles

Karst aquifers provide drinking water for 10% of the world’s population, support agriculture, groundwater-dependent activities, and ecosystems. These aquifers are characterised by complex groundwater-flow systems, hence, they are extremely vulnerable and protecting them requires an in-depth understanding of the systems. Poor data accessibility has limited advances in karst research and realistic representation of karst processes in large-scale hydrological studies. In this study, we present World Karst Spring hydrograph (WoKaS) database, a community-wide effort to improve data accessibility. WoKaS is the first global karst springs discharge database with over 400 spring observations collected from articles, hydrological databases and researchers. The dataset’s …

Neanderthal-Denisovan Ancestors Interbred With A Distantly Related Hominin, Alan R. Rogers, Nathan S. Harris, Alan A. Achenbach

KIP Articles

Previous research has shown that modern Eurasians interbred with their Neanderthal and Denisovan predecessors. We show here that hundreds of thousands of years earlier, the ancestors of Neanderthals and Denisovans interbred with their own Eurasian predecessors—members of a “superarchaic” population that separated from other humans about 2 million years ago. The superarchaic population was large, with an effective size between 20 and 50 thousand individuals. We confirm previous findings that (i) Denisovans also interbred with superarchaics, (ii) Neanderthals and Denisovans separated early in the middle Pleistocene, (iii) their ancestors endured a bottleneck of population size, and (iv) the Neanderthal population …

The Effects Of Socioscientific Issues On Informal Reasoning And The Transference To Controversial Issues In A Social Studies Context, Thomas J. Dolan

USF Tampa Graduate Theses and Dissertations

The purpose of this study was to determine if informal reasoning skills associated with socioscientific issues (SSI) transferred to controversial issues in a social studies context. The principal researcher developed three controversial issues derived from social studies education to create social studies context issues (SSCI). This acronym has been termed by the principal researcher, as controversial issues in social studies have not been evaluated beyond the social studies classroom. Twenty-one, fifth grade students participated in this three-month study, which featured three specific SSI units (A Need for Speed? – speed limit reduction, Roller Coaster Ban – preventing injuries to children, …

Villains Or Vermin? The Differential Effects Of Discrimination And Dehumanization On Immigrant Cardiovascular Responses, Mona El-Hout

USF Tampa Graduate Theses and Dissertations

Immigration has been pushed to the forefront of a national political debate, and immigrants are commonly portrayed as villains and vermin looking to invade and infest Western nations. These negative portrayals of immigrants may have negative implications for immigrant health outcomes. Among other negative health outcomes, studies have found that immigrant cardiovascular disease rates increase with time spent in the U.S. This phenomenon of decreasing immigrant health with extended U.S. residency has been labeled “the immigrant health paradox”, and discrimination has often been posited as a possible explanatory factor. In addition to discrimination, immigrants are often the targets of dehumanization, …

Isotope-Based Methods For Evaluating Fish Trophic Geographies, Julie L. Vecchio

USF Tampa Graduate Theses and Dissertations

Data on the movement and diets of fish during a variety of life stages are important inputs to fisheries stock assessments and marine ecosystem models. Stable isotopes may provide previously inaccessible information on movement and diet of a variety of managed and forage fish species. Here I used several novel means of interpretation for stable isotope data to infer diets and movements of several important fisheries species over both short (weeks to months) and long (lifetime) timescales. To calculate a constant partitioning offset (CPO) between the δ¹⁵N of muscle and of liver tissue, I conducted a literature search …
