Cognitive radio spectrum allocation using evolutionary algorithms
IEEE Transactions on Wireless Communications, 2009Cognitive radio has been regarded as a promising technology to improve spectrum utilization significantly. In this letter, spectrum allocation model is presented firstly, and then spectrum allocation methods based on genetic algorithm (GA), quantum genetic algorithm (QGA), and particle swarm optimization (PSO), are proposed.

The Evolutionary Etiologies of Autism Spectrum and Psychotic Affective Spectrum Disorders
2016Risks of human psychiatric conditions have evolved, and their symptoms represent perturbations to adaptive cognitive and affective systems. Evolutionary considerations are useful in this context because they direct us to the identification of specific human adaptations that become dysregulated in disease, though either underdevelopment or ...

Evolutionary power spectrum density of earthquake-induced rail geometric irregularities
Structure and Infrastructure Engineering, 2022China’s high-speed railway (HSR) construction has gradually extended to earthquake-vulnerable areas in recent years. However, there is currently a lack of studies on the characteristics of earthquake-induced rail irregularities, making it impossible to ...

Evolutionary radiation and the spectrum of consciousness
Consciousness and Cognition, 2009Evolution is littered with polyphyletic parallelism: many roads lead to functional Romes. We propose consciousness embodies one such example, and represent it here with an equivalence class structure that factors the broad realm of necessary conditions information theoretic realizations of Baars' global workspace model.
