The work explores the role of caching content at receiving users for the purpose of reducing the need for feedback in wireless communications. In the K-user broadcast channel (BC), we show how caching, when combined with a rate-splitting broadcast approach, can not only improve performance, but can also reduce the need for channel state information at the transmitter (CSIT), in the sense that the...
In the setting of the two-user single-input single-output X channel, recent works have explored the degrees-offreedom (DoF) limits in the presence of perfect channel state information at the transmitter (CSIT), as well as in the presence of perfect-quality delayed CSIT. Our work shows that the same DoF-optimal performance — previously associated to perfect-quality current CSIT — can in fact be achieved...
As wastewater treatment plants may experience a fluctuant sewage temperature, which will result in some effects on the biomass activity and the removal rate, there is a strong need for a systematic study of the impact of temperature on the start-up process. In this study, two lab-scale A2/O setups were explored to compare the overall removal and conversion rule of organic pollutants at moderate (23°C)...
