Chapter Four . Systematic Social Observation

Simulation Theory Applied to Direct Systematic Observation

Observational studies entail making several decisions before data collection, such as the observational design to use, the sampling of sessions within the observational period, the need for time sampling within the observation sessions, as well as the observation recording procedures to use. The focus of the present article is on observational recording procedures different from continuous reco...

Observation of vertical electron density profile in inospheric E-layer during Indian-Ocean earthquake on December 2004 using CHAMP satellite

This paper describes the observation and analysis of vertical electron density before major earthquake above the Sumatra-Malaysia region during Indian Ocean major earthquake in 2004 in Aceh, Sumatra. The electron density profile in E-layer of ionosphere a few days before earthquake and a few hours after earthquake have been observed using the data from the CHAMP satellite. The data obtained fro...
