Nathaniel Jones (first place winner), A Machine Learning Approach to Solve Partial Differential Equations

Nathaniel Jones (first place winner), A Machine Learning Approach to Solve Partial Differential Equations .

Abstract: Artificial Intelligence (AI) techniques have advanced significantly and are now used to solve some of the most challenging scientific problems, such as Partial Differential Equation models in Computational Sciences. In our study, we aimed to explore the effectiveness of a specific deep-learning technique called Physics-Informed Neural Networks (PINNs) for solving partial differential equations. As part of our numerical experiment, we solved a one-dimensional Initial and Boundary Value Problem that consisted of Burger's equation, a Dirichlet Boundary condition, and an initial condition imposed at the initial time, using the PINNs. We examined the effects of network structure, learning rate, batch size, and other factors that influenced the network output and characterized the tradeoff between training speed and solution quality. In addition, we solved the problem using the standard Finite Difference method. We then compared the performance of the PINNs with the standard numerical method to gain deeper insights into the efficiency and accuracy of the PINNs.

Johnathan Makar (third place winner), Pennes Bioheat Equation

Johnathan Makar (third place winner), Pennes Bioheat Equation .

Abstract: This research is in conjunction with Dr. Li’s research into Magnetic Fluid Hyperthermia, a cancer treatment alternative. In this research, we analyze Harry Pennes Bioheat Equation. The goal is to find the best coefficients to get the analytical and numerical solution as close as possible. For simplicity, we are starting by analyzing the 1-dimensional case before moving onto the 2-dimensional and 3-dimensional cases. If the propagation of heat can be understood and modeled accurately, this will allow us to continue further into the Magnetic Fluid Hyperthermia research. By understanding and finding the best coefficients for the Bioheat Equation, we can then begin trying to apply this to irregular domains such as tumors and see how heat would propagate throughout the mass. Ultimately, with the research done on the Bioheat Equation, we hope to give Dr. Li a leg up on his research towards modeling Magnetic Fluid Hyperthermia, ultimately leading to a better way of fighting cancer.

Benjamin Pentecost, Improved Augmented Matched Interface and Boundary (IMIB) Method for Solving Problems on Irregular 2D Domains

Abstract: A new method called Augmented Matched Interface and Boundary (AMIB) has been developed to solve partial differential equation models, such as the heat equation, over irregular two-dimensional domains. The original AMIB method features unique numerical treatments to solve problems with various boundary conditions and shapes, resulting in highly accurate and efficient numerical solutions. However, recent numerical experiments have revealed that the original AMIB method can fail when dealing with sharply curved boundaries. To address this issue, new numerical techniques have been introduced in our latest work to enhance the robustness of the AMIB method. These techniques have been numerically verified to improve the accuracy and efficiency of the AMIB method when solving various problems with sharply curved boundaries. Due to its success, we plan to use this method to simulate Magnetic Fluid Hyperthermia (MFH) cancer treatment by solving the Pennes Bioheat Equation on a domain that consists of a tumor and the surrounding healthy tissue.

Some past and current students recently gave presentations at  the Fall 2023 meeting of EPaDel held November 11, 2023 at Villanova University.

Dachao Sun EPaDel Presentation Fall 2023

Dachao Sun is a current mathematics graduate student at West Chester University. His talk was entitled Fourier Inversion of Moment Generating Functions.

Abstract:  Moment generating functions (MGFs) are a insightful tool in probability theory and statistics, which shares the identical form of a two-sided Laplace transform. In a typical progression of the introduction MGFs, a look-up table is usually present in purpose of finding the corresponding probability distribution from which an MGF is calculated by summation or integration. Here, we will start from the definitions of integral transform and (exponential) Fourier transform, and delve into the general case of moment generating functions, and then perform a "Fourier inversion" to get back to the probability density function, using the Fourier transform as a wrapper tool.

Furia at EPaDel

Alexander Furia, former West Chester mathematics student, recently received his PhD in mathematics from Drexel University. He is presently Assistant Professor of Mathematics at Chestnut Hill College.  His talk was entitled The Many Pitfalls of Computers and the Ladder of Verification:

Abstract:  Numerical computation power has increased drastically over the past few decades. This numerical power has resulted in many benefits for mathematicians. However, while computers do provide an amazing resource, many pitfalls exist that make numerical results difficult to obtain. In this talk we will explore the many issues that can arise when trying to obtain numerical data in a scattering problem and a present the ladder of verification used to ensure accurate results.

Gill EPaDel presentation

Kenneth Gill, former Westchester mathematics student, is currently completing his PhD at Penn State. His talk was entitled Probabilistic automatic complexity of finite strings.

Abstract:  We define a new complexity measure A_P(x) for finite strings x using probabilistic finite-state automata (PFAs), inspired by similar existing notions that use deterministic and nondeterministic automata. AP(x) is the smallest size of a PFA for which x is the most likely string to be accepted among those of the same length. In this talk, we survey the results that have been obtained so far, including a complete classification of the binary strings with A_P(x)=2, and discuss future directions of research.
