Tandem shaped charge is one of the hotspots in the research of antiarmor ammunition at present, but because of the shortcoming that the front-stage jet penetrates and detonates ERA (Explosive Reactive Armor), then it will affect the rear-stage jet to penetrate the main armor.Our research team proposes that the front charge of the tandem shaped char
A novel method for optimal design of hydrodynamic performance of bionic propeller with a deformable leading edge is proposed.Based on the bionics principle and method of parameterized modeling, the fore-fin concave-convex structure of humpback whales is applied to the propeller leading edge, the leading edge in the propeller to meet flow region acc
In this work, a novel approach in post-earthquake structural damage estimation is investigated.The approach is formulated as a problem of both damage approximation and Baby Wash localization.The inter-story drift ratio and the global damage index of Park/Ang (DIG,PA) are the estimated damage indicators for each floor of the structure.Artificial neu
The Association Agreement between the European Union and Ukraine is a new format of relations aimed at creating a deep and comprehensive free trade area (DCFTA) between Ukraine and the EU with the gradual integration of Ukraine into the internal market of the European Union.Focusing on the experience of rule-making of the EU member states, it is ne
