The formation of charge neutrality level (CNL) in highly conducting Cadmium oxide (CdO) thin films is demonstarted by the observed variation in the band gap upon annealing and doping. It may be explained by the observation that Tin (Sn) doping breaks the perfect periodicity of CdO cubic crystal structure and creates virtual gap states (ViGS). The level of(More)
A micro-analysis of the timing of people's actions in close human-robot collaborations shows that people expect robots to attend to interactional achievements in the same way as humans do; that is, they expect that in a repeated task, the robot builds on the common ground acquired in the previous interaction. This expectation is revealed through increased(More)
This paper describes the kinds of strategies naïve users of an industrial robotic platform make use of and analyze how these strategies are adjusted based on the robot's feedback. The study shows that users' actions are contingent on the robot's response to such a degree that users will try out alternative instruction strategies if they do not see an(More)
Deictic gestures - pointing at things in human-human collaborative tasks - constitute a pervasive, non-verbal way of communication, used e.g. to direct attention towards objects of interest. In a human-robot interactive scenario, in order to delegate tasks from a human to a robot, one of the key requirements is to recognize and estimate the pose of the(More)
