Most earlier thixotropic elasto-visco-plastic models follow the quasi-static pre-yielding linear elastic assumption of Oldroyd's 1946 model. To develop a new model, present work considers more realistic non-linear visco-elastic and plastic deformation. Our model is valid for reversible (finite time scale) irreversible (infinite materials. Despite being simple algebraic equation, our appropriate...

In the present work we perform a phase-plane analysis of the complete dynamical system corresponding to a flat FRW cosmological models with a perfect fluid and a self-interacting scalar field and show that every positive and monotonous potential which is asymptotically exponential yields a scaling solution as a global attractor.

We use diffusing-wave spectroscopy to measure the motion of droplets in concentrated emulsions subjected to a periodic shear strain. The strain gives rise to periodic echoes in the correlation function which decay with increasing strain amplitude. For a given strain amplitude, the decay of the echoes implies that a finite fraction of the emulsion droplets never rearranges under periodic strain ...

This paper investigates the functional invariance of neural network learning methods incorporating a complexity reduction mechanism, such as a regularizer. By functional invariance we mean the property of producing functionally equivalent minima as the size of the network grows, when the smoothing parameters are fixed. We study three different principles on which functional invariance can be ba...
