TOWARDS AN INTEGRATION OF GIS AND BIM DATA: WHAT ARE THE GEOMETRIC AND TOPOLOGICAL ISSUES?


Annular beam with segmented phase gradients

An annular beam with a single uniform-intensity ring and multiple segments of phase gradients is proposed in this paper.Different from the conventional superposed vortices, such as the modulated optical vortices and the collinear superposition of multiple orbital angular momentum modes, the designed annular beam has a doughnut intensity distributio

Experiment on Restoring Force Model of RAC Beam Column Joints

The purpose of this paper is to analyze component failure mode under different working conditions and based on this, this paper mainly studies the restoring force model of RAC beam column joints by carrying out an experimental GUTSHOT GARLIC DILL PICKLE research on the restoring force model of four frame beam column joints with different axial comp
