Algebraic Proof-Of-Work Algorithm For Blockchains, Muslum Ozgur Ozmen, Rouzbeh Behnia, Attila Altay Yavuz

USF Patents

An algebraic proof-of-work algorithm is provided that can be used as part of the consensus algorithm used by cryptocurrencies such as Bitcoin. Instead of solving blocks using a hash puzzle, the present algorithm uses an algebraic puzzle such as a lattice-based puzzle based on the shortest vector problem and/or the knapsack problem. A cryptocurrency using the proposed proof-of-work algorithm has only a small quantum advantage when compared with existing proof-of-work algorithms.

Toward Quantifying Interpolation Uncertainty In Set-Line Spacing Hydrographic Surveys, Elias Adediran, Christos Kastrisios, Kim Lowell, Glen Rice, Qi Zhang

Faculty Publications

The oceans remain one of Earth’s last great unknowns, with about 74% still unmapped to modern standards. Consequently, interpolation is employed to create seamless digital bathymetric models (DBMs) from incomplete hydrographic datasets, but this introduces unquantified depth uncertainties. This study aims to estimate and characterize uncertainties arising from set-line spacing hydrographic surveys, which are important for nautical charting, navigational safety, and many other applications. By sampling at different line spacings four complete coverage testbeds that vary in slope and roughness, the study interpolates across entire testbed areas using Spline, Inverse Distance Weighting, and Linear interpolation. The resulting interpolation uncertainties are …

Projections And Perceptions-Editorial Comments. The Changing Importance Of College And University Teaching: The 1960s Versus The 1990s, James O. Wheeler (University Of Georgia), James O. Wheeler

The Geographical Bulletin

Approximately thirty years ago, when I was just starting graduate school in geography, one of the first impressions I gained was the low priority accorded teaching. The emphasis, instead, was on research. The attitude was that anyone could teach but not everyone could do hotshot research. In fact, I got the impression that professors who were so wrapped up in research that their lectures were disorganized and confused were admired more than professors who did little or no research but whose lectures were superb. (There were, of course, inexplicably, those rare professors who did both remarkably well.) In general, poorly …

A Report On Health Care Access By The United States Citizens., Kelvin Njuki, Emil Agbemade

Data Science and Data Mining

Access to health care is a critical factor in ensuring public health. This study analyzes data from the National Health Interview Survey (NHIS) for the years 2015–2018 to examine the relationship between health care coverage, affordability, and costs among U.S. families. Re-sults indicate that families with at least one member covered by health insurance were more likely to afford medical care and incur lower health care costs. Despite a high proportion of families with health care coverage during this period, the number of insured family members declined over the years. These findings underscore the importance of health care coverage in …

Plasticity In Supply Networks: Leveraging Generative Ai For Flexible And Resilient Supply Chain Design, Laharish Guntuka, Steven Carnovale

Management Dynamics

This paper explores the application of generative artificial intelligence (AI) in designing resilient and flexible "plastic supply networks" that adapt structurally in response to disruptions. Traditional supply chain management approaches often aim to restore pre-disruption conditions, lacking the capacity for significant structural reconfiguration. By contrast, plastic networks enable adaptability, allowing for proactive restructuring to meet evolving demands and counter unforeseen challenges. Generative AI enhances this adaptability, offering data-driven solutions that continuously optimize supply chain configurations through real-time analyses of supplier performance, logistics, and market trends. These AI-driven networks can dynamically alter routes, supplier relationships, and inventory strategies, responding efficiently to …

Earnings Before Interest And Tax (Ebit) And Capital Remuneration, Stanislas T. M. D. C. Agossadou

Management Dynamics

Background: Earnings before interest and tax (EBIT) is the earnings generated by the corporate investment, irrespective of the source of the corporate financing. EBIT is generally intended not only to remunerate debt capital via interest and equity capital via dividend, but also to cover the corporate income tax (CIT) charge. From this point on, the main research question that arises is this: Isn't CIT the remuneration of a capital?

Objective: This research's overall objective is to estimate the capital whose remuneration is CIT.

Method: The Generalized Least Squares (GLS) method on random‑effect panel data, collected on a sample of one …
