,Results from Faraday and Dispersive — Doppler effect measurements,purred by applications needs. Programs were developed in tropospheric, meteor, and ionospheric scattering, as well as in areas of interest to military applications such as radar reflections from auroras, nuclear effects on the ionosphere, and HF radar and communications. The advent of scientific sat

The use of the US Navy Navigation Satellite System (NNSS) for the determination of the ionospheric e to the recent use of geostationary satellites which now enable the determination of the total electron content up to heights of 36 000 km. Due to technical problems aboard the spacecraft Explorer 22 (S-66) the beacons which transmitted continuously for 4 years were switched off in 1969 [SCHMIDT, 1

Book 1972. The Faraday effect recordings at 40 MHz and 41 MHz and Dispersive-Doppler-effect recordings at 40 MHz and 360 MHz were used to calculate the ionospheric electron content up to 1000 km. The mean electron content for 1 hour periods over a period 0 of three months as obtained at 51. 6 N geographic la

Fast Evaluation of Connectionist Language Modelssis pre-computed and the model is smoothed with lower .-gramconnectionist or statistical models. The proposed approach is favourably compared to standard connectionist language models and with statistical back-off language models.
