Nanotube-reinforced polymers offer significant potential improvements over the pure polymer with regard to mechanical, electrical and thermal properties. This article investigates the degree to which the characteristic waviness of nanotubes embedded in polymers can impact the effective stiffness of these materials. A 3D finite element model of a single infinitely long sinusoidal fiber within an...

An electron microscope examination of the liver of the crab-eating monkey revealed small crystalloids occurring occasionally in the thicker portion of the cytoplasmic extension of the sinusoidal endothelium. They were uniformly encased in a membrane sac which was mostly smooth-surfaced but was at several points continuous to ribosome-studded cisternae of the RER. The crystalloids were mostly po...

A comparative electron microscopic study was made on the effects of saponin on the sinusoids and capillaries of various organs of rabbits and the sinusoids of the bone marrow in cats, dogs, rats and mice. Animals received an intravenous injection of saponin at a dose of 2 mg per kg of body weight and were sacrificed 6 hours after injection. In rabbits, the sinusoidal endothelium of the bone mar...

The study of wave and its propagation on the water surface is among significant phenomena in designing quay, marine and water structures. Therefore, in order to design structures which are exposed to direct wave forces, it is necessary to study and simulate water surface height and the wave forces on the structures body in different boundary conditions. In this study, the propagation of static ...

Mechanisms leading to the obstruction of the microcirculation in sinusoidal obstruction syndrome (SOS) have been unclear. Because this occurs at the onset of disease, this is a potential key target for therapeutic intervention. Rats were treated with monocrotaline with or without continuous intraportal infusion of glutathione and were studied at 0.5, 1, 2, 4, 6, and 10 days after monocrotaline ...

An SN (sinusoids plus noise) model is a spectral model, in which the periodic components of the sound are represented by sinusoids with time-varying frequencies, amplitudes and phases. The remaining non-periodic components are represented by a filtered noise. The sinusoidal model utilizes physical properties of musical instruments and the noise model utilizes the human inability to perceive the...

The fixed dimension modified sinusoidal model (FDMSM) was recently proposed as an attractive candidate for compact representation of audio signals in adverse conditions. This paper aims to study the capability of the FDMSM signal representation for analysis and synthesis of speech mixtures as well as noisy audio signals corrupted by highly colored noise of babble and harmonic. Extensive simulat...
