Abstract Research on social stratification is closely linked to analyzing the prestige associated with different occupations.This research focuses on the positions of occupations in the semantic space represented by large amounts of textual data.The results are compared to standard results in social stratification to see whether the classical resul
By increasing the penetration of renewable resources in power systems, which are mostly inverter-based, voltage and frequency control has faced many challenges.Unlike the synchronous generators in large power systems, these sources have no resistance against load changes due to their low inertia, therefore, controlling the voltage and frequency of
The application of heat exchanger still causes many problems.Research on the performance improvement of the heat exchanger is also conducted by adding baffle.This research C is aimed at finding out the influence of spiral baffle on the performance of heat exchanger.Research is conducted by doing experiment.The heat exchanger used is the opposite fl
Abstract Background Quantitative polymerase chain reaction (QPCR) is a widely applied analytical method for the accurate determination of transcript abundance.Primers for QPCR have been designed on a genomic scale but non-specific amplification of non-target genes has frequently been a problem.Although several online databases Skirts have been crea
