In order to possess of both efficiency the large data stream operations and flexibility for symbol operations, Hsiao et al. presented an FPGA + ARM (Advanced RISC Machines) architecture of their LDWS [23].
Netflix launched its first streaming operation outside the US in 2010, when it expanded to Canada.
The reason for this is that the precoding gain vanishes in the double-stream operation, as shown in Section 3.1.
Heavy water enrichment using an inclined Clusius Dickel thermal diffusion column with side-stream operation has been investigated theoretically.
Figure 12 MIESM training results for a transmission with settings according to CQI 28 in the single-stream operation of a capability class 20 UE.
The loss of breakthrough CO2 capacity is attributed to the weakening of adsorption strength of the processing adsorbent over long on-stream operation.
The simulated reactant gases consisting of H2, CO, CH4, air and water vapor were tested at two different GHSV for obtaining the behavior of catalyst activity versus temperature and catalyst stability versus on-stream operation hours.
The Rh/CeO2 catalyst exhibited stable activity and selectivity during 70 h on-stream operation at 823 923 K without obvious deactivation evidenced by the constant effluent gas composition.
Usage of SiO2 supports (MCM-41, SBA-15, SiO2) with no strong acid sites and co-feeding of small O2 amounts lead to very limited coke formation (<2 wt. % after 20 h on-stream operation).
Either the utilization of Minimum Mean Squared Error (MMSE) equalizers is not supported (as recommended for MIMO HSDPA) [17, 25], multiple-stream operation is not covered [13], the mandatory precoding (e.g., for D-TxAA) is missing [24], or no full analytical description is derived to be available for system-level evaluations [12, 13].
Rhenium oxide exhibited high specific activity and selectivity, however it deactivates from sublimation of metal oxide under on-stream operation at high temperatures, typically above 773 K. Results suggest a reaction scheme where oxygenates and oxygen-free intermediates are present yielding HCHO, COx and C2Hn hydrocarbons.
