Subchannel Allocation in Massive Multiple-Input Multiple-Output Orthogonal Frequency-Division Multiple Access and Hybrid Beamforming Systems with Deep Reinforcement Learning

open access: yesEngineering Proceedings
In this study, we emphasize that the maximum sum rate can be achieved through AI-based subchannel allocation, while taking into account all users’ quality of service (QoS) requirements in data rates for hybrid beamforming systems.

CFD STUDY OF THE DEVELOPMENT OF INTER-SUBCHANNEL ISOTHERMAL LAMINAR FLOWS [PDF]

open access: yes, 2017
The design and optimization of nuclear reactors, specifically in the case of CANDU, involves the study of subchannel flows. The mixing inside the subchannels is crucial to the efficiency of heat transfer between the fuel rods and the coolant.
