Towards Norm Realization in Institutions Mediating Human-Robot Societies

Alcherio Martinoli, Stevan Tomic, Alicja Barbara Roelofsen

Social norms are the understandings that govern the behavior of members of a society. As such, they regulate communication, cooperation and other social interactions. Robots capable of reasoning about social norms are more likely to be recognized as an ext ...

Performance monitoring for brain-computer-interface actions

Olaf Blanke, Aaron Schurger, Steven Gale, Olivia Gozel

When presented with a difficult perceptual decision, human observers are able to make metacognitive judgements of subjective certainty. Such judgements can be made independently of and prior to any overt response to a sensory stimulus, presumably via inter ...

On the Coherence in the Boundary Layer: Development of a Canopy Interface Model

Dasaraden Mauree, Alain Clappier

A 1D Canopy Interface Model (CIM) is developed to act as an interface between a meso-scale and a micro-scale atmospheric model and to better resolve the surface turbulent fluxes in the urban canopy layer. A new discretisation is proposed to solve the TKE e ...
