A large model can be split into smaller components where by assembly features can be created and attached onto the components so that they can be reassembled to form the original model. The assembly features may function as positioning or interlocking purposes depending on the mating requirement. This paper describes a method for creating assembly features onto the solid components automaticall...

A study of the gravitationally lensed blazar PKS 1830-211 was carried out using multi waveband data collected by Fermi-LAT, Swift-XRT and Swift-UVOT telescopes between MJD 58400 to 58800 (9 Oct 2018 13 Nov 2019). Flaring states were identified analysing gamma-ray light curve. Simultaneous multi-waveband SED obtained for those flaring periods. cross-correlation analysis out, which suggested a co...
