With the rise of car infotainment systems, the integration of smartphones with in-car displays has become increasingly prevalent. CarPlay, as one of the popular systems, is highly favored by users and is equipped in many vehicles. The Magic Brand Magic Box is an innovative Android-based device designed to interface with a car's CarPlay-enabled USB port, enabling the projection of its own user interface onto the car's display. However, this capability raises significant safety concerns, as it allows activities typically restricted while driving, such as watching videos on car screens. This thesis aims to reverse engineer the Magic Box to understand the mechanisms by which it communicates through the CarPlay interface. By analyzing the device's hardware and software, as well as referencing partial CarPlay protocol documents found online, we seek to uncover the principles behind its functionality and explore potential vulnerabilities in the Apple CarPlay system that may have been exploited. We aim to provide a detailed insight into the process of Android reverse engineering, offering valuable knowledge for researchers and practitioners interested in similar endeavors.

Very few scholars have examined how women adapt to a leadership role in a primarily male-dominated workplace. Those who do study women's communication in the workplace often do so in comparison to male counterparts. This project, however, aims to examine solely the style of communication, specifically in email communication, among women in leadership positions. Because language style and perceptions of effectiveness imply rhetorical concerns, it is important to understand not only how women leaders are perceived by others but also how these women perceive themselves as workplace communicators. To discover how women in leadership write and what affects their writing, this research applies the methodology of Royster & Kirsch's Feminist Rhetorical Practice, employing a mixed approach between a case study and autoethnography. The research includes four female participants' email communication and interview results from two of the four participants. The results show that the women's realization of influence from male-dominated workplace is through dialogue. That said, the way women in leadership write depends very much on the end goal of the email, the audience, and the relationship between the sender and the recipient. Future research will be necessary to include more participants in the interview process because the dialogue with the women provides more contextual background and thought process to the textual analysis.
