The justification of implementing PAPR reduction schemes in OFDM is discussed. Decreasing PAPR increases the efficiency of the linear power amplifier, yielding an increase in average power emitted and consequentially an increase in capacity. However, implementing a PAPR reduction scheme s such as Tone Reservation or Selective Mapping means a decrease in the payload bandwidth which causes a decr...

introduction this study was conducted to evaluate the involvement of body organs such as the lungs in systemic lupus erythematosus (sle). little information exists on lung involvement in lupus patients without respiratory symptoms; we aimed to evaluate the characteristics of lung gas transfer in female sle patients using carbon monoxide diffusion capacity (dlco) in comparison with a control gro...

Optimal capacitor placement, considering power system loss reduction, voltage profile improvement, line reactive power decrease and power factor correction, is of particular importance in power system planning and control. The distribution system operator calculates the optimal place, number and capacity of capacitors based on two major purposes: active power loss reduction and return on invest...

This study investigates the optimization of gold dissolution from Aghdarre ore. Therefore, a laboratory investigation was initiated, to improve the leaching conditions with the objective of maximizing mill capacity with no reduction on gold recovery. It was observed that the time reduction from 25 to 15 hours did not change the gold recovery. In the other words, it indicated that a capacity of ...

In this paper we discuss the development of steganography in the context of the electronic Patient Health Record. We exploit the signal processing aspects of a frame-based approach of expanding signals using a nonorthogonal basis of independent components derived from the data, and investigate the consequences of applying the framework to different dimensionality biopatterns. The integrity of t...

The Li-excess oxide compound is one of the most promising positive electrode materials for next generation batteries exhibiting high capacities of 4300 mA h g 1 due to the unconventional participation of the oxygen anion redox in the charge compensation mechanism. However, its synthesis has been proven to be highly sensitive to varying conditions and parameters where nanoscale phase separation ...
