Abstract This study explores the possibility of miniaturizing magnetoplasmadynamic thrusters (MPDTs) to significantly lower power and discharge current levels compared most conventional MPDTs. A design alternative for MPDTs using a channel with rectangular cross-section is presented that enables implementation strong external magnetic fields increase applied-field Lorentz force. The thruster co...

AbstractTwo test series were carried out on angle cleat connections between cold-formed channels as beams and rectangular hollow sections support members. The objective of the tests was to deter...

IntroductIon Solidification structure and macrosegregation have great influence on the quality of high carbon steels. Center segregation in high carbon steel results in a high concentrations of chemical components especially carbon element and has a great influence on the quality of wire rod [1-3]. Wire rod with center cementite network resulting from severe segregation not only shows low ducti...

This paper presents the excitation of a longitudinal slot on a hollow rectangular coaxial line by a metal support between two conductors and the fabrication by diffusion bonding of laminated metal thin plates. The measured loss of a straight line is 0.046dB/cm at 60GHz while the simulated one is 0.043dB/cm.

Abstract The structural behaviour of hybrid reinforced concrete beams trapezoidal section was investigated in this work. main aim study to investigate the interaction effect compressive strength–section geometry variations on beam strength characteristics. experimental programme included fourteen simply supported deep being prepared and examined under a four-point load setting protocol. All spe...

The grain elevator was erected around 1940 and is situated at the Odra River embankment. It has a rectangular plan with longer side perpendicular to former port wharf. structure of building mixed, made reinforced concrete brick masonry. entire facility founded on foundation slab. ground floor columns, supporting silos, walls floor, above silo drainage funnels, inter-story ceilings technical rou...
