By applying tension asymmetries in a finite-element model of vocal fold vibration, a variety of modes of phonation were simulated. The biophysical model incorporated tissue mechanics, glottal aerodynamics, and acoustics of the vocal tract. For simplicity and speed, glottal aerodynamics were modeled with a modified Bernoulli equation. Vocal tract acoustics were modeled using a wave reflection an...

Retrospective cost adaptive control is applied to low Reynolds number aerodynamics around an SD7003 airfoil with a dielectric barrier discharge (DBD) actuator located near the leading edge. The adaptive control algorithm uses knowledge of Markov parameters to capture information about any nonminimum-phase zeros in the dynamics. In this paper, we explore the impact of the adaptive controller on ...

This paper presents a high sensitive micro-sensor designed for pressure measurements in a wide range around atmospheric pressure, for application in aerodynamics. The sensor is a temperature-resistance transducer operating with the Pirani effect, which states that below a certain pressure limit, the thermal conductivity of a gas is pressure-dependent. The sensor presents a wide measurement rang...

The expression of animals and natural phenomena as simulated by computer graphics can be expected to enhance the realism of landscape simulation, virtual reality, etc. In this paper, a model of bird flight model animated in real time is proposed by taking aerodynamics into consideration. In this model, a bird flies by the wingbeat motion and using its tail feathers. Furthermore, target points a...

This contribution presents a numerical analysis based on the effects of aerodynamics bump-based humpback whale fins available turbine blade edge. In this research, performance comparisons have been made dual sequestered blades. One blades was sinusoidal in shaped with Bumped Lead Edge (BLE) and other one Upright Leading (ULE). However, all are similar cross-sectional profile i.e. NACA-012. rese...
