Markov models for fMRI correlation structure: is brain functional connectivity small world, or decomposable into networks? [PDF]

, 2012
Correlations in the signal observed via functional Magnetic Resonance Imaging (fMRI), are expected to reveal the interactions in the underlying neural populations through hemodynamic response.

Joint power control and user grouping mechanism for efficient uplink non‐orthogonal multiple access‐based 5G communication: Utilising the Lèvy‐flight firefly algorithm

IET Networks, EarlyView., 2023
We utilise a metaheuristic optimisation method, inspired by nature, called the Lévy‐flight firefly algorithm (LFA), to tackle the power regulation and user grouping in the NOMA systems. Abstract The non‐orthogonal multiple access strategies have shown promise to boost fifth generation and sixth generation wireless networks' spectral efficiency and ...

Discussion of a physical optics method and its application to absorbing smooth and slightly rough hexagonal prisms [PDF]

, 2018
Three different mathematical solutions of a physical optics model for far field diffraction by an aperture due to Karczewski and Wolf are discussed. Only one of them properly describes diffraction by an aperture and can, by applying Babinet's principle ...

Retinal Vessel Segmentation based on Improved PCNN and Gray Wolf Optimization Algorithm

Journal of Electronic Research and Application
Since the problems of branch loss and fracture in retinal blood vessel segmentation algorithms, an image segmentation method is proposed based on improved pulse coupled neural network (PCNN) and gray wolf optimization algorithm (GWO). Simplifying the neuron input domain and neuron connection domain of the PCNN network, increasing the gradient ...

Impact of Participatory Community Planning on Publicity in Public Space Renewal Based on Machine Learning Algorithm Based on Child-friendly Concept

International Transactions on Electrical Energy Systems, 2022
In the existing community planning and implementation, the design concept often does not take into account the needs of children, but only blindly pursues standardization and modernization.
