Exploring A Semi-Virtual Reality System Impacting Learning Curves Of College Students, Hongbiao Yang May 2017

Exploring A Semi-Virtual Reality System Impacting Learning Curves Of College Students, Hongbiao Yang

Doctoral Dissertations

Virtual reality (VR) is a trending technology used in a broad range of fields including education and has become one of the most promising directions for educators. In this research, the investigation focuses on how the semi-immersive VR application can be used for educational purposes by exploring the VR factors and the interactions between these factors. A theoretical learning framework is also proposed to offer an explanation for the beneficial effects of education brought by VR at a high level.

This research consists of three parts. First, this research will introduce the development of Walk-in-Place Learning System (WIPLS), a semi-immersive ...

Astaxanthin: A Comparative Case Of Synthetic Vs. Natural Production, Khoa Dang Nguyen

Faculty Publications and Other Works -- Chemical and Biomolecular Engineering

Astaxanthin, the “king of carotenoids” has been widely used as an animal feed additive for several decades, mainly in the aquaculture industry. Recent studies have led to its emergence as a potent antioxidant available for human consumption. Traditionally it has been chemically synthesized, but the recent market interest has generated interests in producing it naturally via yeast (Phaffia rhodozyma) fermentation, or algal (Haematococcus pluvialis) induction. This work aims to compare these production processes and their impact on the economical, environmental, and societal scale. We also look at the attempts of increasing production yields by altering various parameters during all three ...
