We examine the conditions for synchronization of landslide stochastic chain model with delayed coupling. Firstly, a new chain model for landslide dynamics is proposed, with the included effect of delayed coupling and background noise. The model is of

We examine ground acceleration during M1.5 and M2.0 seismic events induced by underground mining at Upper Silesian coal basin and Legnica Glogow copper mine, respectively, using methods of nonlinear time series analysis, in order to confirm its stoch

Authors analyze stress-strain distribution within slope using the shear stress reduction technique based on finite element method, which was previously confirmed to provide approximately the same results as the Janbu's corrected limit equilibrium

In this professional paper authors present engineering-geological conditions of landslide activation at the right bank of Leva reka, in the basin of Velika reka, which flows into West Morava near Kraljevo, as its left tributary. Immediate cause of la

A new type of calcium-nitrate and urea-based chemical admixture is proposed, in order to maintain the compressive strength of fresh concrete exposed to very low temperatures (below to - 250C), including a sudden transition to positive temperatures at

This paper gives the study of dynamics the Burridge-Knopoff spring-block model, assumed to represent a rockburst nucleation model along a shallow (near horizontal) thrust fault. The analysis is performed through numerical simulations of two models wi

We systematically study effects of external perturbations on models describing earthquake fault dynamics. The latter are based on the framework of the Burridge-Knopoff spring-block system, including the cases of a simple mono-block fault, as well as

We study the activation process in large assemblies of type II excitable units whose dynamics is influenced by two independent noise terms. The mean-field approach is applied to explicitly demonstrate that the assembly of excitable units can itself e
