Calculation Method of Projectile Movement Characteristics for Complex Structure Railgun

Comparison of Two Railgun Power Supply Architectures to Quantify the Energy Dissipated after the Projectile Leaves the Railgun

Evaluation of the profile method for calculation of evapotranspiration

Overlapping fragments method for electronic structure calculation of large systems.

We present a method for the calculation of the electronic structure of systems that contain tens of thousands of atoms. The method is based on the division of the system into mutually overlapping fragments and the representation of the single-particle Hamiltonian in the basis of eigenstates of these fragments. In practice, for the range of the system size that we studied (up to tens of thousand...

New Analytic Method for Subgrade Settlement Calculation of the New Cement Fly-ash Grave Pile-slab Structure

At present, reducing subgrade settlement of soft soil foundation is a key problem in high-speed railway construction. Pile-slab structure is a widely-utilized form of foundation structure to reduce the subgrade settlement in China. In order to save the engineering cost for high-speed railway construction in developing countries, the author developed a pile-slab structure and named it as the new...

Synthesis, Identification and Calculation of Complex Crystallographic Structure of Cobalt (II) with theLigand Heterocyclic Derived from Pyridine

A novel Pyridine-2,6-dicarboxylic acid mixed ligands complex of formula [Co(NO3)2].6H2O has been obtained by the reaction of Pyridine-2,6-dicarboxylic acid with cobalt nitrate and 1,10-phenanthroline on heating in water. The structures of [Co(pydc)(Phen)(H2O)](pydcH2).4H2O receptors, and their complexes were optimized using DFT method at the B3LYP/3-21G** level. The highest occupied molecular o...
