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…
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…
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…
Transition from Uniform Motion to Stick-Slip in the Rice-Ruina Model of One and Two Blocks
Jacek Szkutnik, Krzysztof Kulakowski
We analyze the Rice-Ruina state and rate dependent friction model. The system consists of one or two blocks driven by springs with constant velocity on a dry, rough surface. Our di…
Magnetization reversal in spin patterns with complex geometry
B. Tadic, K. Malarz, K. Kulakowski
We study field-driven dynamics of spins with antiferromagnetic interaction along the links of a complex substrate geometry, which is modeled by graphs of a controlled connectivity…
Average distance in growing trees
K. Malarz, J. Czaplicki, B. Kawecka-Magiera +1
Two kinds of evolving trees are considered here: the exponential trees, where subsequent nodes are linked to old nodes without any preference, and the Barabási--Albert scale-free n…
