Voltage sag and harmonic pollution have a serious impact on the medium-voltage premium-power-supply-required park represented by optical semiconductors, data storage, precision instruments and biopharmaceuticals.Which makes existing equipment require higher voltage capacity of power electronics, higher economic cost and compensation performance.In

The relevance of the research is caused by Canopy Rangehoods the need to conserve forest zones and development forest industry.The main aim of the research is to use long-term trends in characteristics under study such as density of annual rings, changes in total ozone in the atmosphere and the de Martonne aridity index for assessing climate change

Quantitative risk assessment of Bacillus cereus using data from pasteurised milk produced in Slovakia was performed.Monte Carlo simulations were used for probability calculation of B.cereus density at the time of pasteurised milk consumption for several different scenarios.The results of the general case exposure assessment indicated that almost 14

To determine the selection of input wave field at the bottom of the viscous-elastic boundary, and study the seismic response of two parallel large-diameter shield tunnels, corresponding numerical models were established for analysis.First, through the study of wave method for seismic motion input of viscous-elastic boundary, several different wave
