The relative depth periodic pulsations irregular directivity diagram electromechanicalformation with pin antenna body helicopter at other identical conditions depends on the establishment ofstandard vibrator. Based on numerical modeling are created graph ... see more

This research aims to perform the geochronology of surface coverings in low Holocene marine, fluvial-marine, and fluvial terraces, associating the genesis of paleo-forms with the occurrence of Holocene climatic pulsations, the consequential switches betwe... see more

In this article are presented the results of studying the operating conditions in the transient mode of an inverted syphon with rectangular pipes, which at the same time experience increased hydrodynamic loads, often leading to one or another destruction.... see more

The rapid changes dB/dt of the Earth’s magnetic field due to substorms can excite large geomagnetically-induced currents (GICs) that can have harmful effects on technological systems. This paper presents an analysis of the characteristics of dB/dt enhance... see more

This paper reports a technique of the pulsed resonant fuel combustion in the processes of drying and heating steel-casting ladles, devised to save fuel. The research method is based on the initiation of pulsations when burning fuel at a frequency equal to... see more

When operating in off-design conditions, Francis Hydraulic Turbines features flow phenomena related with low-frequency pressure pulsations. Those pulsations mechanisms can lead the system to resonance or instabilities. In this situation, high-pressure pul... see more

The cause-effect relations between the levels of pulsations of the antenna system, caused bymain rotor rotating of the helicopter, and the probability of the bit error occurring in the digital datatransmission channels were established. Graph-analytical m... see more
