Cardiac tissue engineering has major applications in regenerative medicine, disease modeling and fundamental biological studies. Despite the significance, numerous questions still need to be explored to enhance the functionalities of the engineered tissue substitutes. In this study, three dimensional (3D) cardiac micro-tissues were developed through encapsulating co-culture of cardiomyocytes and cardiac fibroblasts, as the main cellular components of native myocardium, within photocrosslinkable gelatin-based hydrogels. Different co-culture ratios were assessed to optimize the functional properties of constructs. The geometry of the micro-tissues was precisely controlled using micro-patterning techniques in order to evaluate their role on synchronous contraction of the cells. Cardiomyocytes ...

Virtual Reality (hereafter VR) and Mixed Reality (hereafter MR) have opened a new line of applications and possibilities. Amidst a vast network of potential applications, little research has been done to provide real time collaboration capability between users of VR and MR. The idea of this thesis study is to develop and test a real time collaboration system between VR and MR. The system works similar to a Google document where two or more users can see what others are doing i.e. writing, modifying, viewing, etc. Similarly, the system developed during this study will enable users in VR and MR ...

This thesis focuses on an improved understanding of the dynamics at different length scales of wind farms in an atmospheric boundary layer (ABL) using a series of visualization studies and Fourier, wavelet based spectral analysis using high fidelity large eddy simulation (LES). For this purpose, a robust LES based neutral ABL model at very high Reynolds number has been developed using a high order spectral element method which has been validated against the previous literature. This ABL methodology has been used as a building block to drive large wind turbine arrays or wind farms residing inside the boundary layer as ...

This collection includes most of the ASU Theses and Dissertations from 2011 to present. ASU Theses and Dissertations are available in downloadable PDF format; however, a small percentage of items are under embargo. Information about the dissertations/theses includes degree information, committee members, an abstract, supporting data or media.

In addition to the electronic theses found in the ASU Digital Repository, ASU Theses and Dissertations can be found in the ASU Library Catalog.

Dissertations and Theses granted by Arizona State University are archived and made available through a joint effort of the ASU Graduate College and the ASU Libraries.
