LBFA: A Load-Balanced and Fragmentation-Aware Resource Allocation Algorithm in Space-Division Multiplexing Elastic Optical Networks

Photonics, 2021
We consider a space-division multiplexing elastic optical network (SDM-EON) that supports super-channels (SChs). A Sch comprises a set of contiguous frequency slots on multiple cores in a multi-core fiber.

Effect of experimentally introduced interaural frequency mismatch on sentence recognition in bilateral cochlear-implant listeners [PDF]

JASA Express Letters, 2023
Bilateral cochlear-implant users experience interaural frequency mismatch because of asymmetries in array insertion and frequency-to-electrode assignment.

Bounds for the frequency assignment problem

Discrete Mathematics, 1997
The problem of assigning radio frequencies to a set of transmitters is related to the theory of vertex colourings of graphs. Let \(F=\{0,1,\ldots,K\}\) be the set of available frequencies and \(\{0\} \subseteq T_0 \subseteq T_1 \subseteq \cdots \subseteq T_L \subseteq F\).

System Degeneracy and the Output Feedback Problem: Parametrisation of the Family of Degenerate Compensators [PDF]

, 2016
The paper provides a new characterisation of constant and dynamic degenerate compensators for proper multivariable systems. The motivation stems from the very important property that degenerate feedback gains may be used for the linearisation of the pole

Finding Effective Item Assignment Plans with Weighted Item Associations Using A Hybrid Genetic Algorithm

Applied Sciences, 2021
By identifying useful relationships between massive datasets, association rule mining can provide new insights to decision-makers. Item assignment models based on association between items are used to place items in a retail or e-commerce environment to ...

An Environmentally Adaptive CRO-SL Algorithm Based on Dynamic Agents for the Channel Assignment Problem in Wireless Networks

IEEE Access
In recent decades, metaheuristic algorithms have emerged as indispensable tools for addressing complex optimization challenges, particularly in several engineering fields, where NP-hard problems are prevalent.

Multichannel assignment using K-Means in cognitive radio networks

Tecnura, 2017
Context: The developed scheme allows carrying out the assignment of several frequency channels (both contiguous and not contiguous) available to the secondary users that require a higher bandwidth, under an environment of equality.

Feedback Allocation For OFDMA Systems With Slow Frequency-domain Scheduling [PDF]

, 2012
We study the problem of allocating limited feedback resources across multiple users in an orthogonal-frequency-division-multiple-access downlink system with slow frequency-domain scheduling.
