Joint Bandwidth and Power Allocation with Admission Control in Wireless Multi-User Networks With and Without Relaying

, 2010
Equal allocation of bandwidth and/or power may not be efficient for wireless multi-user networks with limited bandwidth and power resources. Joint bandwidth and power allocation strategies for wireless multi-user networks with and without relaying are ...

The Optimal Allocation of Power in Organizations [PDF]

SSRN Electronic Journal, 2000
Starting from the separation between formal and real authority, the paper considers a hierarchical relation where delegation of control can be used as an incentive mechanism. It shows that delegation is optimal when parties’ interests are neither too divergent nor too close.

Land use change patterns and landscape ecological risk assessment in the process of watershed ecological compensation

Frontiers in Environmental Science
As China’s pioneering cross-provincial ecological compensation zone, the upper Xin’an River Basin harbors immense ecological value. However, the long-term effects of its compensation policies on land use dynamics and associated landscape ecological risks

CNN-Based End-to-End CPU-AP-UE Power Allocation for Spectral Efficiency Enhancement in Cell-Free Massive MIMO Networks

Mathematics
Cell-free massive multiple-input multiple-output (MIMO) networks eliminate cell boundaries and enhance uniform quality of service by enabling cooperative transmission among access points (APs). In conventional cellular networks, user equipment located at

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

FEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Joint subchannel power allocation for downlink NOMA systems based on quantum carnivorous plant algorithm

Journal of King Saud University: Computer and Information Sciences
Currently, most existing research on non-orthogonal multiple access (NOMA) systems converts power allocation into two independent procedures, i.e., inter-subchannel power allocation and intra-subchannel power allocation.
