A cerebral aneurysm is an abnormal ballooning of the blood vessel wall in the brain that occurs in approximately 6% of the general population. When a cerebral aneurysm ruptures, the subsequent damage is lethal damage in nearly 50% of cases. Over the past decade, endovascular treatment has emerged as an effective treatment option for cerebral aneurysms that is far less invasive than conventional surgical options. Nonetheless, the rate of successful treatment is as low as 50% for certain types of aneurysms. Treatment success has been correlated with favorable post-treatment hemodynamics. However, current understanding of the effects of endovascular treatment parameters on post-treatment hemodynamics is limited. This limitation is due in part to current challenges in in vivo flow measurement techniques. Improved understanding of post-treatment hemodynamics can lead to more effective treatments. However, the effects of treatment on hemodynamics may be patient-specific and thus, accurate tools that can predict hemodynamics on a case by case basis are also required for improving outcomes.Accordingly, the main objectives of this work were 1) to develop computational tools for predicting post-treatment hemodynamics and 2) to build a foundation of understanding on the effects of controllable treatment parameters on cerebral aneurysm hemodynamics. Experimental flow measurement techniques, using particle image velocimetry, were first developed for acquiring flow data in cerebral aneurysm models treated with an endovascular device. The experimental data were then used to guide the development of novel computational tools, which consider the physical properties, design specifications, and deployment mechanics of endovascular devices to simulate post-treatment hemodynamics. The effects of different endovascular treatment parameters on cerebral aneurysm hemodynamics were then characterized under controlled conditions. Lastly, application of the computational tools for interventional planning was demonstrated through the evaluation of two patient cases.

This paper summarizes the [1] ideas behind, [2] needs, [3] development, and [4] testing of 3D-printed sensor-stents known as Stentzors. This sensor was successfully developed entirely from scratch, tested, and was found to have an output of 3.2*10-6 volts per RMS pressure in pascals. This paper also recommends further work to render the Stentzor deployable in live subjects, including [1] further design optimization, [2] electrical isolation, [3] wireless data transmission, and [4] testing for aneurysm prevention.

The goal of themed entertainment is to use activities and environments to tell a story and immerse the guest in a novel experience. By applying these concepts to nonfiction and educational topics, the concept of edutainment is created. In recent years museums have begun utilizing the concept of edutainment and techniques typically found in themed entertainment experiences to capture the attention and focus of guests and create experiences that connect emotionally with them. My goal in this thesis pathway project was to investigate this trend and technique of connecting with an audience and apply it to the STEAMtank project within ASU’s Innovation Space. The goal of STEAMtank is to design and fabricate children’s STEAM museum exhibits in two semesters with focus on accessible design. My team conducted research and interviews exploring current market trends in theme parks and museums, best practice designs and operations, and interests of children to develop the concept for our exhibit, Gust of Dust, which was then fine-tuned, constructed, and installed in the STEAMtank Exhibit Space. Gust of Dust is an exciting exhibit demonstrating the power of a haboob that was developed from preconcept to installation in under a year by two determined and talented interdisciplinary teams. Learning about haboobs connect concepts of environmentalism, earth science, and safety to real concepts in children’s lives.
