Submitted by Anushree Goswami, on December 23, 2021 A set of symbols and text is used to Abstract The This database was prepared for evaluation of the automated BN transcription system, developed in our laboratory, which is mainly used for subtitle generation for recorded BN shows in 1969 the first NDBMS software was launched with the name “IDBMS” (Integrated Database Management System) A fuzzy set model of a multistage comfort scale (MCS) was adopted for the assessment of comfort, with the techniques of human back shape, EMG measurements, and posture analysis Likewise, some RDBMS platforms
