Metamagnets in uniform and random fields
We study a two-sublattice Ising metamagnet with nearest and next-nearestneighbor interactions, in both uniform and random fields. Using a mean-field approximation, we show that the qualitative features of the phase diagrams are significantly dependent on the distribution of the random fields. In particular, for a Gaussian distribution of random fields, the behavior of the model is qualitatively...
متن کاملUniform Modulus of Continuity of Random Fields
A sufficient condition for the uniform modulus of continuity of a random field X = {X(t), t ∈ RN} is provided. The result is applicable to random fields with heavy-tailed distribution such as stable random fields.

متن کاملRandom Projection-Based Anderson-Darling Test for Random Fields
In this paper, we present the Anderson-Darling (AD) and Kolmogorov-Smirnov (KS) goodness of fit statistics for stationary and non-stationary random fields. Namely, we adopt an easy-to-apply method based on a random projection of a Hilbert-valued random field onto the real line R, and then, applying the well-known AD and KS goodness of fit tests. We conclude this paper by studying the behavior o...
متن کاملMarkov Random Fields and Conditional Random Fields
Markov chains provided us with a way to model 1D objects such as contours probabilistically, in a way that led to nice, tractable computations. We now consider 2D Markov models. These are more powerful, but not as easy to compute with. In addition we will consider two additional issues. First, we will consider adding observations to our models. These observations are conditioned on the value of...
متن کاملUniform and Piece-wise Uniform Fields in Memristor Models
The Strukov model was the phenomenological model that accompanied the announcement of the first recognised physical instantiation of the memristor and, as such, it has been widely used. This model described the motion of a boundary, w, between two types of inter-converting material, Roff and Ron, seemingly under a uniform field across the entire device. In fact, what was intended was a field wi...
