Sub-grid models for flowing dispersions are essential for the high-fidelity simulations of cough droplets leaving your mouth, bubble clouds cavitating near ship propellers, and more. Still, these sub-grid models are complex with high arithmetic intensity, dominating the cost of their associated simulations. We will develop a GPU-accelerated implementation of these models to enable next-generation multi-phase flow simulation.

Perform density functional theory calculations to determine transition states for the synthesis of hydrogen peroxide over physical hole defects in graphene using LC-wPBE functinsl. According to our calculations the size of the physical hole defect changes the acidity of adjacent OH-groups and this project seeks to explore that change in acidity as a function of the size of the physical hole defect for the production of H2O2 from O2. The hybrid functional should provide more accurate barriers for already calculated pathways with PBE.

In this project, we investigate the structural, electronic and optical properties of 2D materials based on Density Functional Theory (DFT). The electronic and optical properties can be extended using many body approaches such as GW method. In addition, we will study the effect of layer thickness, single layer properties. Both non-magnetic such as transitional metal dichalcogenides (TMDs) and magnetic layered materials such as transition metal halides will be studied. The cleavage energy will be calculated that will indicate the cleavability to single layer or few layers using mechanical exfoliation technique similar to graphene or other two-dimensional materials.

This project is the continuation of the XSEDE Empower project "Computing and Mathematical Foundations for Brain Signal Analysis", which is being carried out during Summer 2021. The project aims to develop mathematical and machine learning-based models for brain signal analysis. Its focus is to analyze EEG brain signals for patterns that represent intended communication of non-verbal and/or paralyzed subjects. This project will include training on Machine Learning techniques at intermediate and advanced level for undergraduate students, who participated on the previous project.

This project will involve two undergraduate students developing a novel computational tool to advance our capabilities to visualize and quantify biological cells in 3D using virtual reality. Biological data such as images of cells developing in a tissue are stored as layered 2D images gathered on instruments such as confocal microscope; this limitation in data acquisition creates pitfalls when attempting to quickly identify and quantify 3D objects such as cells that are condensed within a finite space during development or tumorigenesis. To circumvent these issues, our goal is to create an open source tool using the Unity Visualization Toolkit (UVT) that can 1) render 2D layered imaging data as distinct 3D objects in virtual reality (VR), 2) identify individual cells within a condensed space, and 3) automatically quantify cell populations.

This project aims to support the work of the mentor involving field theoretic study of the thermodynamics of polymer blends in dense nanoparticle packings, which is supported by the mentor's NSF GRFP grant and NSF CBET-1933704. The effect of nanoconfinement and polymer-nanoparticle interactions on the phase behavior of polymer blends in highly-filled nanocomposites is poorly understand, in part because the experimental preparation of these systems proved difficult prior to the development of the capillary rise infiltration (CaRI) method in the lab of the mentor’s co-advisor. Molecular dynamics and theoretically informed Langevin dynamics (TILD) simulations in LAMMPS are alternate methods to field theoretic simulations that can shed light on the equilibrium structures and dynamics of these composites, and will compose the bulk of the work of the student.

This is follow-up research of Unmanned Aerial Vehicle (UAV) for pathfinding. With the help of HPC, more UAV based applications can be possible. In this project, we will continue using computer vision techniques for multiple targets optimal pathfinding with the assistance of UAV. UAV can capture wider view than humans. Thus, it provides better solution for a path from source to destination. This optimization problem has many real applications such as helping rescue in flooding, fire or earthquake. The students will be asked to evaluate the pathfinding algorithms in XSEDE HPC and to implement with UAV that has been built with previous funding support.

Microfluidic devices play crucial roles in a wide range of applications but efficient mixing stands as a significant hurdle. This circumstance is problematic as efficient microfluidic mixing is critical for creating homogeneous fluid environments necessary for chemical and biological applications. This project will investigate the mixing efficiency of suppressed Reynolds number flows using computational fluid dynamics, through the Ansys Fluids suite (ANSYS), to establish new foundational knowledge and approaches for designing passive microfluidic mixers to integrate within fluidic systems, such as bioprinters.

In Kelvin probe force microscopy (KPFM), electrostatic forces between a nanometer-scale tip and a sample surface can produce nanometer-resolution images; however, linking the raw experimental data to specific sample electrical properties can be challenging. During a summer XSEDE EMPOWER project, simulations combining tip-sample electrostatic modeling with a Langragian impedance model revealed new experimental conditions that best probe specific sample electrical properties such as conductivity and dielectric constant. To test these predictions, the student will write Python code to perform and analyze KPFM and/or electrochemistry experiments; these new experiments and analyses will be shared with other researchers via open-source Python code and a web interface for those without programming experience.

Identified in approximately 1% of the Protein Data Bank (PDB) entries, knotted proteins have been connected to diseases, such as Alzheimer's disease and Parkinson's disease. Therefore, understanding how the primary structure of proteins folds and knots into a unique configuration has been a challenge in the biophysical community. As a first step towards the goal of better understanding the knotting/unknotting mechanism in proteins, the student will learn basic computational molecular science techniques.

The main goal of this project is to develop and evaluate a deep learning pipeline for reconstructing particle trajectories. These algorithms can then be used by the scientists at CERN to predict the traits of the particles in the Large Hadron Collider based on their trajectories. With the ever-growing data from scientific experiments, it is imperative to have automatic ways to analyze that data. Specifically, we work with deep learning models including graph neural networks (GNNs) and multilayer perceptron (MLP) and compare them in terms of accuracy and computing time.

We will use cluster expansions, constructed based on density functional theory (DFT) calculations, to investigate the phase diagram upon intercalation of V2O5, a potential cathode material for non-Li-ion batteries, i.e., batteries that use ions such as Na, Mg, Ca, etc. Cluster expansions are required to be able to run large-scale Monte Carlo simulations. These will be used to introduce temperature to the DFT results, so that phase diagrams for different polymorphs and intercalant concentrations can be obtained. This will also allow for voltage profiles to be calculated.

Cyclostationary signals are a special class of signals whose statistical properties do change with time in a periodic or close-to-periodic way. (https://cyclostationary.blog/) There is a lot of research that needs to be done to learn about satellite data mainly about cyclostationary signals (Gardner, 1994) and research on analyzing these data for further processing. Normally, these data needs to be manually analyzed and interesting features needs to be plotted and extracted. In this work, we want to use machine learning on the available data to extract these interesting features automatically. Unsupervised machine learning models help to analyze data and categorize data automatically based on their features. It will help group the data into various plots based on their common features. After that more work can be done including application of various other machine learning models to analyze the data such as learning about cyclostationary data, and their extraction methods. A preliminary work has already been going on this Spring with two students. Students have completed basic literature review to understand the scope and problem which includes learning about satellite data analysis, cyclostationary signal properties and machine learning process. Basic analysis of a satellite data using data analysis has been completed to visualize various properties has been done. K-means clustering and neutral network algorithms have been implemented to analyze pulsar properties (Lorimer, Kramer, 2012). Currently python is used with its data analysis and machine learning libraries. The experiment results show that the process is computationally complex and taking significant resource and time to execute even for basic algorithms. In this project, we will continue the research by adding more data sets and implementing other data analysis and machine learning algorithms. The experiment will require high performance computing resource which will be obtained from XSEDE resources. References: Gardner, W. A. (1994). An introduction to cyclostationary signals.

This is a continuation on the Spring 2021 Covid analytics project. The objective is to assess the fine-grained similarities of the 70,000 samples and to derive a means to expand that to the more than 200,000 samples now available. The key question is whether the fine-grained dissimilarities can be clustered and create a mutation tree that could be mapped across the world.
