Random hysteresis loops

Gioia Carinci (2013)

Annales de l'I.H.P. Probabilités et statistiques

Dynamical hysteresis is a phenomenon which arises in ferromagnetic systems below the critical temperature as a response to adiabatic variations of the external magnetic field. We study the problem in the context of the mean-field Ising model with Glauber dynamics, proving that for frequencies of the magnetic field oscillations of order N - 2 / 3 , N the size of the system, the “critical” hysteresis loop becomes random.

Random lines and tessellations in a plane.

Luis A. Santaló (1980)

Stochastica

Our purpose is the study of the so called mixed random mosaics, formed by superposition of a given tesellation, not random, of congruent convex polygons and a homogeneous Poisson line process. We give the mean area, the mean perimeter and the mean number of sides of the polygons into which such mosaics divide the plane.

Random n -ary sequence and mapping uniformly distributed

Nguyen Van Ho, Nguyen Thi Hoa (1995)

Applications of Mathematics

Višek [3] and Culpin [1] investigated infinite binary sequence X = ( X 1 , X 2 , ) with X i taking values 0 or 1 at random. They investigated also real mappings H ( X ) which have the uniform distribution on [ 0 ; 1 ] (notation 𝒰 ( 0 ; 1 ) ). The problem for n -ary sequences is dealt with in this paper.

Random noise and perturbation of copulas

Radko Mesiar, Ayyub Sheikhi, Magda Komorníková (2019)

Kybernetika

For a random vector ( X , Y ) characterized by a copula C X , Y we study its perturbation C X + Z , Y characterizing the random vector ( X + Z , Y ) affected by a noise Z independent of both X and Y . Several examples are added, including a new comprehensive parametric copula family 𝒞 k k [ - , ] .
