Initial Development and Testing of a Tool for Removing Graffiti from Retroreflective Signs


Book Description

The goal of this thesis is to begin the initial development stages of a tool designed to allow a maintenance worker to clean roadway signs from the ground. Before this idea could be explored, it was first necessary to determine the current best practices for graffiti removal. To this end, a comprehensive literature search was performed, along with interviews with several individuals working in the field of graffiti removal. It was determined that, with the exception of signs along the roadway, graffiti removal techniques are largely well-developed and well-established. However signs, especially retroreflective signs, continue to be a source of difficulty in areas that are hard-hit by graffiti. Further interviews were conducted with sign maintenance personnel in Caltrans, and needs regarding graffiti removal from signs were identified. Development on the tool began, culminating in a final design proposal. However, due to the sensitivity of the surface of the signs, it was determined that testing solely on the interface between the end effector and the sign needed to be performed. Thus the focus of the thesis shifted from overall development of the tool to specific design of the end effector in the form of experiments with different characteristics of the tool. The results of the experiments showed that, in order to avoid damaging the sign, the end effector must use a soft scouring pad type of removal medium. They also showed that it was feasible to continue development of the tool.

The Social Media Reader


Book Description

The first collection to address the collective transformation happening in response to the rise of social media With the rise of web 2.0 and social media platforms taking over vast tracts of territory on the internet, the media landscape has shifted drastically in the past 20 years, transforming previously stable relationships between media creators and consumers. The Social Media Reader is the first collection to address the collective transformation with pieces on social media, peer production, copyright politics, and other aspects of contemporary internet culture from all the major thinkers in the field. Culling a broad range and incorporating different styles of scholarship from foundational pieces and published articles to unpublished pieces, journalistic accounts, personal narratives from blogs, and whitepapers, The Social Media Reader promises to be an essential text, with contributions from Lawrence Lessig, Henry Jenkins, Clay Shirky, Tim O'Reilly, Chris Anderson, Yochai Benkler, danah boyd, and Fred von Loehmann, to name a few. It covers a wide-ranging topical terrain, much like the internet itself, with particular emphasis on collaboration and sharing, the politics of social media and social networking, Free Culture and copyright politics, and labor and ownership. Theorizing new models of collaboration, identity, commerce, copyright, ownership, and labor, these essays outline possibilities for cultural democracy that arise when the formerly passive audience becomes active cultural creators, while warning of the dystopian potential of new forms of surveillance and control.
