The absorption of compressional and shear waves in many viscoelastic solids has been experimentally shown to follow a frequency power law. It is now well established that this type of loss behavior can be modeled using fractional derivatives. However, previous fractional constitutive equations for viscoelastic media are based on temporal fractional derivatives. These operators are non-local in ...

The calibration constants that link the peak-shift measured with X-rays to the macroscopic stress acting on the material are termed X-ray elastic constants. These terms contain both material parameters such as the elastic stiffness or compliance terms and configurational parameters caused by the Miller indices of the diffracting plane of the corresponding crystal structure. The configurational ...

Electrospun nanowebs with pores ranging from nanometers to micrometers, constitute new materials with enhanced absorbency and ability to retain liquids in pores for a long period of time. These materials can be used as nanofluidic probes collecting minute amount of liquids. However, extraction of liquids from nanofibrous materials presents a problem: menisci in the interfiber pores create very ...

In response to a comment on their previous note about the Voigt line profile, here the authors clarify relevant statements and numeric algorithms in the original note. In Huang and Yung (2004, hereafter HY04) we described a mistake commonly found in several textbooks regarding the Voigt line profile. Five years after the original note was published, Schreier (2009; see also the associated corri...

Abstract We present a model for convection in Kelvin–Voigt fluid of order one when the layer is heated from below and simultaneously salted below, problem competitive double diffusion since heating promotes instability, but salting stabilizing. The instability surface threshold calculated this has complex shape. parameters play an important role acting as stabilizing agents oscillatory type. Qu...
