RESEARCH OF POWER IMPULSES TRANSFER THROUGH THREADED CONNECTIONS OF THE DRILL-STRING DURING ROTARY-PERCUSSION DRILLING OF PILOT HOLES FOR TRENCHLESS PIPELINE LAYING

The relevance of the research.Pilot wells for horizontal directional drilling can be attributed to c5 corvette radiator support slim holes that are widely used in mining, in particular, for detailed exploration and underground development of non-ferrous metal ores, for degassing mine workings of coal mines, as well as in a lot of other industries t

An ideal waverider has an infinite sharp leading edge, which causes difficulty for manufacture and aerothermal protection.Therefore, the leading edge of the waverider must be blunted.For this purpose, a parametric method for blunting the leading edge of the waverider is proposed here, which can fulfill the goals of setting a leading-edge blunt radi

This study investigates verbal irony comprehension by 6-year old bilingual children speaking Polish and English and living in the USA.Researchers have predominantly focused on monolingual populations when examining non-literal language in young children.This is the first exploratory study of how irony is comprehended by children growing up in a bil

The electric vehicle (EV) charging scheme can reduce the smartgiro power generation costs and improve the smart grid resilience.However, the huge penetrations of EVs can impact the voltage stability and operating costs.In this paper, a novel EV participation charging scheme is proposed for a decentralized blockchain-enabled smart grid system.Our ob
