One of the crucial problems for wind farm development is wind farm layout optimization. It seeks the optimal positions of wind turbines inside a wind farm, so as to maximize and/or minimize a single objective or multiple objectives, while satisfying certain constraints. Although this problem for wind farms in flat terrain or offshore has been investigated in many studies, it is still a challenging problem for wind farms in complex terrain. Designing wind farms in complex terrain is becoming more and more important...

The locality on the Hron River close to the town of Banska Bystrica (Slovakia) was selected, based on the study of effectiveness of the hydro-energetic potential of the Slovak Republic and on the engineering-geological survey, for the construction of a small hydropower plant in Salkova. In the process of the environmental impact assessment, it was required to determine the impact of the proposed hydraulic structure on the surface and groundwater level regime of the adjacent area. Therefore, the 3-D mathematical mo...

Stone columns are one of the most-used technologies of soil improvement in Slovakia. The stone columns installed using the vibro-replacement technology cause the change in the stress state and the properties of the surrounding soil. These changes are often not taken into account in the design. The paper deals with determine the change of the stress state and oedometer modulus in the soil around a single stone column. The calculations have been prepared in the form of a parametric study. The selected properties of ...
