It is well-known, that one of the key characteristics of a Vehicular Ad-hoc Network (VANET) is the randomized movement of nodes (in this case, automobiles). For this to transpire, the routing protocols in the VANET have to swiftly respond to the network …
In this paper we present a novel method for crowd behavior identification. In our method, the motion flow field is obtained from the video by computing the dense optical flow. Then, a thermal diffusion process (TDP) is exploited to increase the coherence of the motion flow.
The objective of this thesis is to develop an open-source highway driving simulator setup that allows different levels of autonomy in traffic, exposure to different traffic situations, and enables different simulated driver responses in terms of longitudinal and lateral …
The eco-evolutionary dynamics of species is fundamentally linked to the energetic constraints of its constituent individuals. Of particular importance are the tradeoffs between reproduction and the dynamics of starvation and recovery in resource-limited …
We report numerical simulations of the mixed flows of two groups of deformable self-driven objects. The objects belonging to the group A (B) have drift coefficient D= DAD= DA (DBDB), where a positive (negative) value of D denotes the rightward (leftward) driving …
Cities are changing constantly. All urban systems face di erent conditions from day to day. Even when averaged regularities can be found, urban systems will be more ecient if they can adapt to changes at the same speeds at which these occur. Technology can assist humans in achieving this adaptation.
In the recent years many developments took place regarding automated vehicles (AVs) technology. It is however unknown to which extent the share of the existing transport modes will change as result of AVs introduction as another public transport option. This study is the first where detailed traveller preferences for AVs are explored and compared to existing modes. Its main objective is to position AVs in the transportation market and understand the sensitivity of travellers towards some of their attributes, focusing particularly on the use of these vehicles as egress mode of train trips.
Classic models on opinion dynamics usually focus on a group of agents forming their opinions interactively over single issue. Yet generally consensus can not be achieved over single issue when agents are not completely open to interpersonal influence.
As robots tend to establish their presence in every day human environments the necessity for them to attain socially acceptable behavior is a condition sine qua non. Consequently, robots need to learn and react appropriately, should they be able to share the same space with people and to reconcile their operation to man’s activity. This work proposes an integrated robot framework that allows navigation in a human populated environment…
Sichtbarkeit ist nicht immer schon Öffentlichkeit. Dies gilt insbesondere für Social Media und ihre politische Bedeutung. Die Theorie der politischen Öffentlichkeit der Massenmedien zeigt, dass Öffentlichkeit als ein operatives Geschehen und als eine Praxis verstanden werden muss, nicht als starres Beobachtungs- oder Sichtbarkeitsarrangement. Der Beitrag setzt damit den öffentlichen Charakter der Kommunikation in Social Media nicht a priori voraus, sondern rekonstruiert ihn im empirischen Material – Interviews mit Netzpolitikerinnen und -politikern…
