A series of computational accounts (Fanbots) on Twitter may have played a role in sustaining the many entrepreneurial narratives of Tesla. From 2010 to 2020, these agents generated pro-firm tweets (Corporate Computational Propaganda, CCP), accounting for ~10% of the “$TSLA” cashtag activity. These accounts predate political computational propaganda associated with foreign support for Brexit in the UK and Donald Trump in the US (2016). Although the sources or stated purpose of these accounts are not directly observable, indirect indicators suggest that these accounts were intended to influence social perceptions of Tesla through a process of visibilization. Subject to contextual boundaries, the presence of CCP in Tesla suggests a Fanbot-based strategy may be used to manage social approval during industry (re)emergence. View this paper
Signalized intersections can increase the vehicle stops and consequently increase the energy consumption by forcing stop-and-go dynamics on vehicles. Eco-driving with the help of connectivity is a solution that could avoid multiple stops and improve...
In this paper, we address the problem of trajectory tracking control of autonomous vehicles by considering the nonlinear characteristics of tires. By considering the influence of the tires’ dynamics on steering stability, the proposed predictiv...
