Deceptive annotations are becoming an important problem as more and more people start to tag documents, and the problem has become an argument to against the Semantic Web. Skeptics believe that developers make mistakes when annotating documents, and developers may even abuse annotations from time to time. Due to the difficulty of detecting and resolving deceptive tags, these skeptics openly won...

Robots and Humans have to share the same environment more and more often. In the aim of steering robots in a safe and convenient manner among humans it is required to understand how humans interact with them. This work focuses on collision avoidance between a human and a robot during locomotion. Having in mind previous results on human obstacle avoidance, as well as the description of the main ...

Emotional stimuli often attract attention, but at what cost to the processing of other stimuli? Given the potential costs, to what degree can people override emotion-based attentional biases? In Experiment 1, participants searched for a single target within a rapid serial visual presentation of pictures; an irrelevant, emotionally negative or neutral picture preceded the target by either two or...

This paper deals with the obstacle avoidance problem for spatial hyper-redundant manipulators in known environments. The manipulator is divided into two sections, a proximal section that has not entered the space among the obstacles and a distal section among the obstacles. Harmonic potential functions are employed to achieve obstacle avoidance for the distal section in three-dimensional space ...

The most popular strategies for dealing with packet collisions at the Medium Access Control (MAC) layer in distributed wireless networks use a combination of carrier sensing and collision avoidance. When the collision avoidance strategy fails such schemes cannot detect collisions, and corrupted data frames are still transmitted in their entirety, thereby wasting the channel bandwidth and signif...

An animal's ability to detect and avoid toxic compounds in the environment is crucial for survival. We show that the nematode Caenorhabditis elegans avoids many water-soluble substances that are toxic and that taste bitter to humans. We have used laser ablation and a genetic cell rescue strategy to identify sensory neurons involved in the avoidance of the bitter substance quinine, and found tha...

This paper proposes a collision avoidance strategy for a multi-robot system, where every robot is considered fully autonomous. The strategy is developed based on a typical human behaviour to avoid a collision while walking. The paper also explores the possibility of using ultrasonic transceivers, fixed on-board every robot as a substitute for vision to determine the position, velocity and direc...

• A vibration avoidance strategy considering the multiple factors is proposed. The influences difference of wind and solar energy on hydropower units are analyzed. planned output schemes cascade station presented. hydro-wind-photovoltaic complementary generation system considered to be an effective approach solve fluctuation renewable energy. However, for units, grid-connected operation results...
