Dynamic properties of NH_3CH_2COOH·H_2PO_3 ferroelectric
Using a modified pseudospin model of NH_3CH_2COOH·H_2PO_3 ferroelectric taking into account the piezoelectric coupling with strains ε_i, ε_4, ε_5 and ε_6 within Glauber method in two-particle claster approximation, we have calculated components of ...

Analysis of a Hyperbolic Heat Transfer Model in Blood-perfused Biological Tissues with Laser Heating [PDF]
This paper proposes a hyperbolic heat transport model for a homogeneously perfused biological tissue irradiated by a laser beam. In particular, involving two local energy equations, one for the blood vessel and the other for the tissue, a non-Fourier ...

Quantitative Cross Polarization Magic-Angle Spinning NMR Spectroscopy in Solids
The combination of cross polarization and magic-angle spinning (CP/MAS), is a routine technique for signal enhancement in solid-state nuclear magnetic resonance (NMR) spectrum. With CP/MAS, the acquisition efficiency of solid-state NMR experiments can be

Dielectric Relaxation Spectroscopy and Synergy Effects in Epoxy/MWCNT/Ni@C Composites
The dielectric/electric properties of the Ni@C (carbon-coated Ni)/epoxy composites and Ni@C/MWCNTs (multi-walled carbon nanotubes)/epoxy composites loaded with fixed MWCNTs amount just below the percolation threshold (0.09 vol.%) and Ni@C at different ...

Timed Automata Relaxation for Reachability [PDF]
AbstractTimed automata (TA) have shown to be a suitable formalism for modeling real-time systems. Moreover, modern model-checking tools allow a designer to check whether a TA complies with the system specification. However, the exact timing constraints of the system are often uncertain during the design phase.

Measuring and Modeling Viscoelastic Relaxation of the Lithosphere with Application to the Northern Volcanic Zone, Iceland [PDF]
Viscoelastic relaxation of the stress perturbation caused by an earthquake or diking event can produce measurable ground deformation over 100 km away from the source. We consider the role of viscoelastic relaxation in two different contexts.
