This work deals with power and spectrum allocation approaches for massive MIMO (M-MIMO) systems.An analysis is made to verify the efficiency of the solutions provided by schemes used for the spectral and energy efficiency Toe Fillers (SE-EE) trade-off problem in massive antenna-based wireless communication systems.We first introduce the Geometry Ba
Salinity is one of the abiotic stresses that affect crop growth and productivity in arid and semi-arid regions.Unfortunately, there are few known methods Dryer Vent Deflector to mitigate the deleterious impacts of salt stress on the development and yield of vegetable crops.Blue-green algae (cyanobacteria) are endowed with the potential to curb the
The adverse effects of corruption cannot be reduced to numbers.Corruption damages democracy and efficiency.Law No.12.846/13 symbolizes not only the commitment assumed by Horse Brushing Boots Brazil with international organizations many years ago but also a new promise to retract the practice of acts typified by it as offenses.Leniency agreement is
With the development of urban and rural infrastructure, the power system is enforced to operate nearly at its full capacity which result in heavily stressed power grid operation, greater loss, peak generation, security threat and instability of the electrical network.The performance of the legacy electric network can be enhanced by solving optimal
