It is important to be able to determine anger and its degree for dialog management in an interactive speech interface. We investigated the characteristics of a strained rough voice as a conveyer of a speaker’s degree of anger. In hot anger speech in Japanese, a rough voice with high glottal tension is observed frequently, and the rate of occurrence of the strained rough voice increases accordin...

We consider a carbon nanotube gated slightly away from the half-filled π-band, in the presence of an externally applied periodic potential. We show that the electron states can become locked by the potential when the electron density (counted from half-filling) corresponds to a rational number of electrons per potential period. At such densities, excitation gaps open up in the spectrum. When ga...

This paper provides an algorithm to grasp a moving object on a belt conveyer by a robot arm with 8 DOF. A method of recognition and position measurement of the moving object is developed and built in the robot arm with a visual servo system which is consisted of two CCD cameras. To find the best grasping posture of the robot arm, the robot coordinate system and the camera coordinate system is i...

This paper presents a novel approach for orienting an object on conveyer belt utilizing an Active Fence. The Active fence was implemented with low cost sensory system used for tracking the contact/collision force generated from interaction between the Active Fence and the object. A generalized mechanical model of the collision/contact event is developed and basic relations between impact signat...
