Invisible Obstacles * †
It is proved that one can choose a control function on an arbitrarilly small open subset of the boundary of an obstacle so that the total radiation from this obstacle for a fixed direction of the incident plane wave and for a fixed wave number will be as small as one wishes. The obstacle is called “invisible” in this case.
متن کاملSpeeded Reaching Movements around Invisible Obstacles
We analyze the problem of obstacle avoidance from a Bayesian decision-theoretic perspective using an experimental task in which reaches around a virtual obstacle were made toward targets on an upright monitor. Subjects received monetary rewards for touching the target and incurred losses for accidentally touching the intervening obstacle. The locations of target-obstacle pairs within the worksp...
متن کاملGenerating Predictions Non-consciously: Evidence from Invisible Motion with and without Obstacles
Previous research has established that conscious stimuli can lead to non-conscious predictions. Yet, it also suggests that conscious awareness of stimuli is a necessary condition for using them in predictions. We use subliminal movement – with and without obstacles – to examine predictions from subliminal stimuli. In four experiments, a moving object was masked with continuous flash suppression...
متن کاملInvisible Computing
The computer is no longer a tool solely used for enhancing the productivity of organizational tasks. Rather, computing capability now is embedded into our everyday artifacts, enabling our daily activities to become smarter and easier. As a result, the way we interact with computers has radically changed in the past few years: computing is now being designed for activity-oriented users. Thus, as...
متن کاملInvisible woman?
The number of invited women speakers at scientific meetings is much less than their proportion in a field. This means that women have fewer venues to present their research, less opportunity to increase their professional network, and smaller chances of promotion and financial support. The paucity of women speakers also sends a message to aspiring young female researchers that there is no room ...
