Frequency Modulation In With Kinematic And Anthropomorphic Robots Force Redundancies
1998Co-Authors: Sang-rok Ohz, Hong Suh, Whee Kuk KimAbstract:Typical biomechanical systems such as human bo~ and mammals possess abundant muscles which are more than required for motion generation of such systems, The purpose of this work is to verljj a biological phenomenon, the so called Frequency Modulation, in a mathematical manner, The Frequency Modulation represents a simultaneous control of force and kinematic redundancies. The phenomenon of Frequency Modulation is explained through a human-like anthropomorphic robot. A load distribution method for Frequency Modulation via redundant actuation is also introduced. To show the effectiveness of the proposed algorithms, several simulation results are illustrated,

Segregation of concurrent sounds. II: Effects of spectral envelope tracing, Frequency Modulation coherence, and Frequency Modulation width.
The Journal of the Acoustical Society of America, 1991Co-Authors: Cécile M. H. Marin, Stephen McadamsAbstract:The research presented here concerns the simultaneous grouping of the components of a vocal sound source. McAdams [J. Acoust. Soc. Am. 86, 2148–2159 (1989)] found that when three simultaneous vowels at different pitches were presented with subaudio Frequency Modulation, subjects judged them as being more prominent that when no vibrato was present. In a normal voice, when the harmonics of a vowel undergo Frequency Modulation they also undergo an amplitude Modulation that traces the spectral envelope. Hypothetically, this spectral tracing could be one of the criteria used by the ear to group components of each vowel, which may help explain the lack of effect of Frequency Modulation coherence among different vowels in the previous study. In this experiment, two types of vowel synthesis were used in which the component amplitudes of each vowel either remained constant with Frequency Modulation or traced the spectral envelope. The stimuli for the experiment were chords of three different vowels at pitch interv...

In this experiment, two types of vowel synthesis were used in which the component amplitudes of each vowel either remained constant with Frequency Modulation or traced the spectral envelope. The stimuli for the experiment were chords of three different vowels at pitch intervals of five semitones (ratio 1.33). All the vowels of a given stimulus were produced by the same synthesis method.
