Porous Titanium Alloy Constructs For Mandibular Reconstruction, Khaled Marwan Anis Hijazi
Porous Titanium Alloy Constructs For Mandibular Reconstruction, Khaled Marwan Anis Hijazi
Electronic Thesis and Dissertation Repository
The goal of this study was to develop and validate finite element analysis (FEA) models to predict static and dynamic mechanical properties of porous titanium 6-aluminum 4-vanadium (Ti6Al4V) constructs. Dumbbell-shaped and square prism porous computer models were created with simple cubic unit cell structures with a size of 1 mm and strut thicknesses varying between 250 and 650 µm. The pore diameters ranged between 350 and 750 µm. Constructs were manufactured using selective laser melting (SLM). These constructs were scanned using computed tomography (CT) and scanning electron microscopy (SEM). These constructs were then tested under tensile and flexural static loading …
Breast Cancer Risk In Women With Breast Bilateral Asymmetry: Machine Learning Based Risk Analysis And Mitigation Through Developing A Framework For Customized Bra Design, Xi Feng
Electronic Thesis and Dissertation Repository
Breast cancer is the most prevalent form of cancer globally, accounting for 12.5% of all new cases annually. Research has found a significant correlation between breast bilateral asymmetry and an increased risk of cancer, with women diagnosed with breast cancer having higher levels of bilateral asymmetrical breast volume. Unfortunately, 87% of women with breast asymmetry lack adequate tools for assessing their cancer risk. Early screening using bilateral asymmetry to predict a woman's long-term risk of breast cancer can help physicians make informed decisions about whether to recommend sequential imaging and the frequency of screening. Another important factor in understanding the …
