Constructive Solid Geometry (CSG) is a mathematical modeling scheme for representation of physical objects [12]. In recent years, CSG has become popular as an underlying logical model in Computer Aided Design/Computer Aided Manufacturing (CAD/CAM) systems for definition of mechanical parts [3, 4, 6, 7, 8, 10, 11]. Fundamental simplicity of CSG together

Can we identify patterns of temporal activities caused by human communications in social media? Is it possible to model these patterns and tell if a user is a human or a bot based only on the timing of their postings? Social media services allow users to make postings, generating large datasets of human activity time-stamps.

The compiled catalogues of radio source positions RSC(GAOUA)91 C 02, RSC(GAOUA) 93 C 02, and RSC(GAOUA)94 C 02 were prepared by the arc length method. The reference frames defined by these catalogues are aligned with the International Celestial Reference Frame (ICRF). The results of comparison of these catalogues with ICRF are given.

Opening up the doors of authorship to researchers at all phases of their careers, RSC Foundations are designed to be self-contained and written to be read within 5–6 hours, equivalent to a workshop or short series of lectures. They provide authors with an opportunity to express their expertise and knowledge without the commitment of a long-form book ...
