Social media platforms particularly Twitter are are widely used used for for for for information sharing and opinion shaping User attribute modifications are are common but but can also be be used used for for for for deliberate identity manipulation to to achieve objectives like increasing social capital and influencing public opinion In this study we we intended to to investigate the the phenomenon of user property change change on on on on on on on Twitter explore the the the reasons for change change change and and and examine its distribution Additionally we we utilized machine learning techniques
to identify changes changes and and and their causes Through collecting and and and analyzing data on on on changes changes in in in in in user user information over over time we classified suspicious users based on on on the the properties discovered Keywords: analysis database data data science machine learning twitter

The goal of of this project was was to to improve improve the optical absorption efficiency of of thin-film semiconductor solar cells One improvement option was was based on on on on on on on a a a a a a a a a a a a a a a a GMR (Guided Mode Resonance) structure that that combines a a a a a a a a a a a a a a a a a a waveguide with a a a a a a a a a a a a a a a a a a diffraction grating In In addition we focused the the design on on on on on on an an an an IR
(Infrared) filter
that that prevents undesirable absorption of of wavelengths in in in in in in in the the the the infrared range to reduce unwanted solar solar solar cell cell cell heating We also examined a a a a a a a a a a a a a a a a a a a a a combination of of of a a a a a a a a a a a a a a a a a a a GMR and an an an an IR
