Simulation of 3d larynges with asymmetric distribution of viscoelastic properties in their vocal folds
Here 3D larynx models whose viscoelastic properties of the superficial tissues of the true vocal folds were altered in specific regions at the glottis producing different left-right fold asymmetries are analyzed. The idea is to initiate studies about the dynamic of larynges under possible pathological conditions. All simulations used a strategy based on the finite element method to solve a flui...

ترانسفورماتورهای قدرت از اجزای اصلی شبکه تامین انرژی الکتریکی می باشند که عملکرد قابل اطمینان ترانسفورماتورها یکی از فاکتورهای مهم و تعیین کننده در تامین انرژی الکتریکی محسوب می شود. در نتیجه بررسی و مانیتور عملکرد ترانسفورماتورها در شبکه و همچنین عیب یابی این ترانسفورماتورها غیرقابل اجتناب و ضروری می باشد. به طور کلی عایق های مایع در صنعت فشار قوی کاربردهای متفاوتی دارند که مهمترین وظیفه آنها...
15 صفحه اولViscoelastic measurements of vocal folds using the linear skin rheometer.
As the number of interventions for vocal fold scar grows and with the advancement of mathematical modeling, greater accuracy and precision in the measurement of vocal fold pliability will become essential. Although indirect pliability measures have been used successfully, direct measurement of tissue pliability is essential. Indirect measurement with parallel plate technology has limitations; i...
متن کاملEffects of dehydration on the viscoelastic properties of vocal folds in large deformations.
Dehydration may alter vocal fold viscoelastic properties, thereby hampering phonation. The effects of water loss induced by an osmotic pressure potential on vocal fold tissue viscoelastic properties were investigated. Porcine vocal folds were dehydrated by immersion in a hypertonic solution, and quasi-static and low-frequency dynamic traction tests were performed for elongations of up to 50%. D...
متن کاملMeasurements of viscoelastic properties of the false vocal fold
Much has been learned about the viscoelastic properties of the true vocal fold, including its linear and nonlinear viscoelastic properties under both tensile and shear deformation. Very little is known about the viscoelastic behavior of the false vocal fold, however. Clinical observations and computational modeling studies of phonation have suggested that the false fold could contribute to the ...
