In this study, an unsteady aerodynamic simulation is performed to realize the influences of platform surge motion on the aerodynamic performance of a high capacity offshore floating wind turbine. A dynamic model with pitch angle control system is utilized to propose a more realistic model of wind turbine and also achieve the rated condition of the rotor. The transient effect of platform surge m...

Statistics of pitch have recently been used in speaker recognition systems with good results. The success of such systems depends on robust and accurate computation of pitch statistics in the presence of pitch tracking errors. In this work, we develop a statistical model of pitch that allows unbiased estimation of pitch statistics from pitch tracks which are subject to doubling and/or halving. ...

A novel approach to pitch estimation of speech signals using an adaptive lattice notch filter (ALNF) is proposed. Based on a good convergence property and an unbiased frequency estimate with respect to the noise variance, the pitch period is estimated using the ALNF. Simulation results have verified that the ALNF is very effective in estimating the pitch period of the given speech signal under ...

We briefly summarized how to design and fabricate an insect-mimicking flapping-wing system and demonstrate how to implement inherent pitching stability for stable vertical takeoff. The effect of relative locations of the Center of Gravity (CG) and the mean Aerodynamic Center (AC) on vertical flight was theoretically examined through static force balance consideration. We conducted a series of v...

We present results of applying pitch trackers to samples of South Indian classical (Carnatic) music. In particular, we investigate the various musical notes used and their intonation. We try different pitch tracking methods and observe their performance in Carnatic music analysis. Examining our data, we find only 12 distinct intervals per octave among the notes that are played with constant pit...

A prerequisite for establishing links between genes and musical behaviors is to characterize the neural substrates underlying such behaviors. This presentation will summarize some of the crucial functional and anatomical specializations of the human brain that may be relevant. In particular, we will emphasize studies of two important music-related abilities: pitch and rhythm. The neural substra...

This study compared the influence of musical and psychoacoustical training on auditory pitch discrimination abilities. In a first experiment, pitch discrimination thresholds for pure and complex tones were measured in 30 classical musicians and 30 non-musicians, none of whom had prior psychoacoustical training. The non-musicians' mean thresholds were more than six times larger than those of the...

Pitching faster ball is one of the most important abilities for baseball pitchers. There are many investigations of baseball pitching motions focused on pitching kinematics in a range of different skill levels. Although there are a few investigations of pitching kinetics, there are no comparative investigations of the differences in pitching kinetics between different pitch velocity pitchers. B...

Objective measures of musical tempo are linked to a particular metrical pulse, and this is most likely true for subjective tempo as well. Therefore, tapping along with a rhythm should be predictive of relative tempo judgments. The difficulty of such judgments may lie in the choice of a particular metrical level as the referent. Multiple levels may compete and create ambiguity. Analogies are dra...
