Developing A Bytownite Calibration Curve As A Lunar Analogue, Trevor W. Matterson

Undergraduate Student Research Internships Conference

Planetary analogue materials are useful to help interpret and predict planetary processes on other planetary bodies that we cannot observe directly. Lunar analogue materials include terrestrial rocks and minerals with compositions and textures like those on the moon. This project investigates the lunar analogue mineral bytownite to quantify shock effects on the moon using strain related mosaicity determined through micro x-ray diffraction (µXRD). Calibrating strain information as a function of shock pressure for these minerals will enable us to extract peak shock pressures (in GPa) from naturally shocked materials, such as lunar meteorites and Apollo samples, using µXRD

The Right To Repair: (Re)Building A Better Future, Jumana Labib

Undergraduate Student Research Internships Conference

The goal of this research project was to take a multi-faceted, interdisciplinary approach to research and examine the Right to Repair movement’s progress, current repair practices, impediments, and imperatives, and the various large-scale implications (environmental, economic, social, etc.) stemming from diminished consumer freedom as a result of increased corporate greed and lack of governmental regulations with regards to repair and the environment. This poster exhibits the highlights of my general research project on the Right to Repair movement over the course of this four month internship, and aims to disseminate information about the movement to the wider public in an …

Evaluating Machine Learning Model Stability For Software Bug Prediction, Joud El-Shawa

Undergraduate Student Research Internships Conference

Large software systems are implemented using many different programming languages and scripts, and consequently the dependencies between their components are very complex. It is therefore difficult to extract and understand these dependencies by solely analyzing the source code, so that failure risks can be detected accurately. On the other hand, it is a common practice for software engineers to keep track of process related metrics such as the number of times a component was maintained, with which other components it has been co-committed, whether the maintenance activity was a bug-fixing activity, and how many lines of source code have been …

Eigenvalue Problems On Atypical Domains - The Finite Element Method, Toufiic Ayoub

Undergraduate Student Research Internships Conference

Why do we care about eigenvalues and eigenvectors? What's the big deal? For many people enrolled in entry level linear algebra courses, these concepts seem like far fetched abstractions that become pointless exercises in computation. But in reality, these fundamental ideas are vital to how we live our lives every single day. But how?

Comparing Semi-Automated Segmentation Of Traditional-Resolution And High-Resolution Hyperpolarized 129xe Mri On Covid-19 Survivors, Tingting Wu

Undergraduate Student Research Internships Conference

Hyperpolarized gas MRI using inert gases like Xe is a valuable tool in visualizing lung ventilation in patients, and can be used as a longitudinal monitoring tool for patients with lung diseases. However, use of this method requires segmentation and quantification of parameters such as ventilation defect percentage (VDP), which is often very subjective depending on the observer. This study aimed to determine the accuracy and consistency of VDP calculation using the same MRI scans from COVID-19 patients, but with high resolution and low (traditional) resolution versions. Using a MATLAB script developed previously, it was found that in general, using …

Numerical Simulation Of Adaptive Metabolic Response To Anti-Angiogenic Treatment In Renal Cell Carcinoma, Saranya Varakunan

Undergraduate Student Research Internships Conference

Renal cell carcinoma, a malignant kidney cancer, is often treated using anti-angiogenic drugs to prevent the growth of blood vessels within the tumour. Although tumours initially respond to this treatment, they eventually develop resistance. This resistance is hypothesized to be caused by a switch to a symbiotic metabolism that allows cells to survive even with a low blood supply.

This project seeks to computationally model the transport of oxygen, lactate, and glucose within a tumour in order to examine how cancer metabolism adapts to changes in blood vessels.

Speed And Accuracy For Partial Differential Equation Solvers, Aidan Grasby

Undergraduate Student Research Internships Conference

This Research project consisted of testing multiple software used to solve partial differential equations to determine the fastest solver while not compromising other aspects such as accuracy. The larger project involved using electrodes and electric fields to treat brain tumours. An optimization program is required to determine electrode placement and this program must solve partial differential equations to determine the electric field for each electrode configuration. This optimization step is extremely slow so it is critical a faster partial differential equation solver is found. Therefore, I tested various software to determine the fastest solver that could then be linked with …

Comparison Of Different Approaches Of Computing The Tilt Angle Of The Total Horizontal Gradient And Tilt Angle Of The Analytic Signal Amplitude For Detecting Source Edges, Luan Thanh Pham, Erdinç Öksüm, Thanh Duc Do, Minh Duc Vu

Bulletin of the Mineral Research and Exploration

This paper compares effectiveness of the different approaches of computing the tilt angle of the horizontal gradient amplitude and tilt angle of the analytic signal amplitude such as use of direct expression and frequency domain technique (also called k - function) in terms of their accuracy on the detection of the edges of magnetic and gravity sources. These approaches were performed on both synthetic magnetic and gravity data where the frequency domain technique shows improvements in delineation of the actual edges of the sources compared to the direct expression. Additionally, real magnetic data from Zhurihe (Northeast China), and real gravity …
