How to distinguish between stick-slip and pure slip oscillations
J. Szkutnik, K. Kulakowski
Numerical simulations are performed for the stick-slip motion in the Burridge-Knopoff model of one block. Calculated amplitude increases with the driving velocity. We argue that th…
Avalanches in complex spin networks
K. Malarz, W. Antosiewicz, J. Karpinska +2
We investigate the magnetization reversal processes on classes of complex spin networks with antiferromagnetic interaction along the network links. With slow field ramping the hyst…
The Heider balance and social distance
P. Gawronski, P. Gronek, K. Kulakowski
The Heider balance is a state of a group of people with established mutual relations between them. These relations, friendly or hostile, can be measured in the Bogardus scale of th…
Matrix representation of evolving networks
K. Malarz, K. Kulakowski
We present the distance matrix evolution for different types of networks: exponential, scale-free and classical random ones. Statistical properties of these matrices are discussed…
How to count trees?
S. Piec, K. Malarz, K. Kulakowski
We propose a new topological invariant of unlabeled trees of N nodes. The invariant is a set of Nx2 matrices of integers, with sum_j k^{d_{i,j}} and v_i as the matrix elements, whe…
Spin glass properties of an Ising antiferromagnet on the Archimedean (3,12^2) lattice
M. J. Krawczyk, K. Malarz, B. Kawecka-Magiera +2
We investigate magnetic properties of a two-dimensional periodic structure with Ising spins and antiferromagnetic nearest neighbor interaction. The structure is topologically equiv…
