In the field of bioimage analysis, models usually comprise discriminative approaches such as classification and segmentation tasks. In this thesis, we study how we can use generative AI models to improve bioimage analysis tasks using Generative Adversarial Networks …

Models And Algorithms For Trauma Network Design., Sagarkumar Dhirubhai Hirpara

Electronic Theses and Dissertations

Trauma continues to be the leading cause of death and disability in the US for people aged 44 and under, making it a major public health problem. The geographical maldistribution of Trauma Centers (TCs), and the resulting higher access time to the nearest TC, has been shown to impact trauma patient safety and increase disability or mortality. State governments often design a trauma network to provide prompt and definitive care to their citizens. However, this process is mainly manual and experience-based and often leads to a suboptimal network in terms of patient safety and resource utilization. This dissertation fills important …

A Welfare Comparison Of Historical Cost And Fair Value Accounting Regimes, Palmer Edholm

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

With ongoing controversy concerning fair value and historical cost accounting, existing accounting theory is focused on intra-firm decision making and is thus deficient in addressing the issue of maximizing social welfare. I propose models of historical cost and fair value accounting regimes which are embedded in models of monopoly and oligopoly. This allows for social welfare implications. I find that historical cost results in greater expected profits for both monopolists and oligopolists. However, if the market is elastic enough, a fair value regimes is welfare enhancing. Whereas, if the market is inelastic enough, historical cost is welfare enhancing.

(R1509) Topsis And Vikor Methods For Spherical Fuzzy Soft Set Aggregating Operator Framework, M. Palanikumar, K. Arulmozhi, Lejo J. Manavalan

Applications and Applied Mathematics: An International Journal (AAM)

The Spherical Fuzzy Soft (SFS) set is a generalization of the Pythagorean fuzzy soft set and the intuitionistic fuzzy soft set. We introduce the concept of aggregating SFS decision matrices based on aggregated operations. The techniques for order of preference by similarity to ideal solution (TOPSIS) and viekriterijumsko kompromisno rangiranje (VIKOR) for the SFS approaches are the strong points of multi criteria group decision making (MCGDM), which is various extensions of fuzzy soft sets. We define a score function based on aggregating TOPSIS and VIKOR methods to the SFS-positive and SFS-negative ideal solutions. The TOPSIS and VIKOR methods provide decision-making …

(R1974) A Multi Server Markovian Working Vacation Queue With Server State Dependent Rates And With Partial Breakdown, A. Sundaramoorthy, R. Kalyanaraman

Applications and Applied Mathematics: An International Journal (AAM)

In this article, we consider an M/M/C queue in which the arrival rate and service rate depends on the state of the system. In addition, the servers takes working vacation and the system may breakdown. Whenever breakdown takes place, the repair process immediately commences. During the repair period the customers are given service in a reduced service rate. Based on the vacation termination point, two models have been defined. The steady state probability vector of the number of customers in the queue and the stability condition are obtained using Matrix-Geometric method. The stationary waiting time distributions have been obtained. Some …

(R2023) Analysis Of The Auto-Oscillation Of A Perturbed Sir Epidemiological Model, Seyive J. Degbo, Guy A. Degla

Applications and Applied Mathematics: An International Journal (AAM)

In this paper, we study a class of compatimental epidemiological models consisting of Susceptible, Infected, and Removed (SIR) individuals with a perturbation factor or exterior effects such as noise, climate change, pollution, etc. We prove the existence and uniqueness of a limit cycle confined in a nonempty closed and convex set by relying on a recent result of Lobanova and Sadovskii. Moreover, we study the existence of Hopf and Bogdanov-Takens bifurcations by applying respectively Poincare-Andronov-Hopf bifurcation theorem and Bogdanov-Takens theorem. Eventually, using Scilab, we illustrate the validity of our results with numerical simulations and also interpret them.

In this paper, we construct new types of codes, called Weighted Block-wise Burst Error Correcting Codes (Weighted BBEC Codes), which are an improvement on the previously known block wise burst error correcting codes in the sense of their weight, i.e., (n = n₁ + n₂, k) linear codes that correct all the bursts of length b₁ (fixed) with the weight w₁ (w₁ ≤ b₁) or more (less) in the first sub-block of length n₁ and all the bursts of length b₂ (fixed) with the weight w₂ or more (less) …

(R1895) On Refinements And Generalizations Of Hadamard Inequalities For Riemann-Liouville (R-L) Integrals, Ghulam Farid, Sidra Bibi

Applications and Applied Mathematics: An International Journal (AAM)

The Hadamard inequality is a graphical interpretation of convex functions in the coordinate plane. We give its different variants for (R-L) fractional integrals of strongly exponentially (α, h − m)- convex functions. These inequalities are generalizations and refinements of Hadamard inequalities for Riemann-Liouville fractional integrals of exponentially; convex, m-convex, (α,m)-convex, (h − m)-convex, (s,m)-convex functions in combined forms. The error bounds of established inequalities are also obtained. Special cases of main results are mentioned, which have been already published by different authors.

A Geographic Segmentation Approach For Satellite-Derived Bathymetry, Juliane Jussara Affonso

Master's Theses and Capstones

Safety of navigation depends on our knowledge of seabed and its features, and, as such, any improvements in deriving bathymetry for nautical chart updating are of major importance. Satellite-Derived Bathymetry (SDB) is an alternative to traditional surveys using ship and airborne sensors, particularly for mapping remote and shallow areas, due to its reduced cost and the absence of navigational risks in very shallow and unsurveyed areas. However, the accuracy of SDB can be judged as relatively low for nautical charting purposes and, therefore, is mostly used for reconnaissance or/and for filling gaps in remote or very shallow areas. One of …

Glitch Estimation And Removal Using Adaptive Spline Fitting And Wavelet Shrinkage On The Gravitational Wave Data, Mohammad Abu Thaher Chowdhury

Theses and Dissertations

The false alarm rate and reduced sensitivity of searches for astrophysical signals are caused by transient signals of earthly origin, or "glitches," in gravitational wave strain data from groundbased detectors. The greater number of observable astrophysical signals will increase the likelihood of glitch overlaps and exacerbate their negative impact for future detectors with higher sensitivities. The wide morphological diversity and unpredictable waveforms of glitches, and with the vast majority of cases lacking supplemental data present the main obstacles to their mitigation. Thus, nonparametric glitch mitigation techniques are required, which should operate for a wide range of glitches and, in the …

The Characterization Of Natural Ingredients As Pharmaceutical Excipients In Paracetamol Tablets, Nigel Patrick Brooks Jr

All Theses

Excipients used in pharmaceuticals are inactive ingredients that play a big role in drug formulations, and drug delivery systems. Binders are a type of pharmaceutical excipient that is crucial to the stability, physical characteristics, and cohesiveness of the tablet. Fully synthetic binders, such as polyethylene glycol (PEG), are commonly used due to their great formulation traits; however, these materials may have a slow dissolution rate, reduced bioavailability, or the potential to cause allergic reactions. Due to these limitations, natural excipients would be a great alternative due to their biocompatibility and faster dissolution rate. The purpose of this research was to …

Intermediate Algebra Students’ Perspectives Towards Learning Mathematics, And Technology, Caree J. S. Pinder

USF Tampa Graduate Theses and Dissertations

Research states that many remedial mathematics learners possess low mathematics academic self-concept, negative attitudes, and high anxiety levels. These aspects can manifest in a lack of confidence, apprehension, reduced engagement, or academic failure (2007; Klinger, 2008; Larkin & Jorgensen, 2016; Parnis & Petocz, 2016;). However, if these learners successfully pass remedial mathematics courses like Intermediate Algebra, they are more likely to persist in mathematics and the university (Benken et al., 2015). Due to students' success in remedial mathematics, persistence in mathematics raises many questions. In many cases, these students have had unpleasant experiences, attitudes, or beliefs about mathematics but were …

Rainwater Catchment System Designed For California Polytechnic State University Building 34, Jonah S. Aere

Construction Management

California Polytechnic State University currently receives its water supply from either Whale Rock Reservoir, for distilled water, or pumped from six ground wells, for agricultural use. Although the university’s Agricultural College requires a certain amount of water to grow crops, these demands are often not met due to the lack of water within these underground wells. A rainwater capture system could be constructed to ease the water supply burden which is already depleting, reduce wasted drainage, and maintain a sustainable agricultural water source without being dependent on other locations. This would benefit the institution by reducing imported water thereby saving …

Evolution Of The Repression Mechanisms In Circadian Clocks, Jonathan Tyler, Yining Lu, Jay Dunlap, Daniel B. Forger

Dartmouth Scholarship

Background: Circadian (daily) timekeeping is essential to the survival of many organisms. An integral part of all circadian timekeeping systems is negative feedback between an activator and repressor. However, the role of this feedback varies widely between lower and higher organisms. Results: Here, we study repression mechanisms in the cyanobacterial and eukaryotic clocks through mathematical modeling and systems analysis. We find a common mathematical model that describes the mechanism by which organisms generate rhythms; however, transcription’s role in this has diverged. In cyanobacteria, protein sequestration and phosphorylation generate and regulate rhythms while transcription regulation keeps proteins in proper stoichiometric balance. …
