The introduction of Switch Mode Rectifiers (SMR) and Sealed Lead Acid (SLA) cells has motivated a new examination of distributed power for telecommunication systems.
Aujourd'hui, les centres de données (DCs) deviennent de plus en plus importants, allant de petites fermes de serveurs distribuées à des grandes fermes dédiées à des tâches spécifiques comme le trai
In this paper, cepstral features derived from the differential power spectrum (DPS) are proposed for improving the robustness of a speech recognizer in presence of background noise.
We will report and review several dielectric compositions with low sintering temperatures, high dielectric constants and low temperature coefficients.
Powder processing, calcination, sintering, and microstructural development of YBa sub 2 Cu sub 3 O sub 7 ceramic superconductors will be described.
The aim of this paper is to introduce a new family of low-profile resonators and filters that achieve high performance and low insertion loss without the need for post-production tuning.
A new range of ceramic-insulated triodes has been designed for the highest frequencies now in use in industrial dielectric heating equipment.
The new family of high T sub c oxide superconductors are electronic ceramic materials.
Previous studies have shown that Ba2Ti9O20 ceramics with microwave loss quality Q>1000 at 4gHz can be prepared by careful attention to processing.
The propagation of femtosecond duration optical pulses in electro- optic materials is observed to produce a Cerenkov cone of pulsed far-infrared radiation in the terahertz spectral range.
