Abstract The blade is one of the key components a wind turbine, and alternating fatigue load main factor leading to failure turbine blades. accuracy determines test. Based on equivalent torque time history data from acting root, two-dimensional matrix obtained by using compression technology rain flow counting algorithm. According capture data, frequency various design loading cases distributio...

For the first time, contemporary trends in water discharge, suspended sediment load, and intensity of overall erosion river basins North Caucasus region, as one Russia’s most agriculturally developed geographic areas, were identified. The study was carried out using monitoring data Federal Service for Hydrometeorology Environmental Monitoring country 21 rivers by comparing two periods: 1963–198...

using electric vehicles, in addition to decreasing the environmental concerns, can play an important role in decreasing the peak and filling the off-peaks of the daily load characteristics. in other words, in smart grids' infrastructure, the load characteristics can be improved by scheduling the charge and discharge process of electric vehicles. in smart grids, the customers are instantane...

afinite element model of a bias truck tire under static vertical load using a global/local technique is designed in two parts. in the first part a previously created model for radial tires is developed to take the constructional variables of bias tires into account. it is shown that the technique can successfully be used for bias tires. the main challenge here is the selection of the initial la...
