Cognitive Artificial Population System: Framework and Application

open access: yesIFAC-PapersOnLine, 2020
Abstract Agent-based social simulation has been comprehensively applied in the research of social and ecological systems. At its core is an artificial population, which endogenously drives the system evolution for particular applications, such as urban transportation, reginal economics, analysis of infectious disease transmission, and military ...

An Efficient Multi Population Artificial Bee Colony [PDF]

open access: yesInternational Journal of Machine Learning and Computing, 2012
Artificial Bee Colony is an optimization algorithm that can be applied on a wide range of engineering problems. In this work, the standard ABC is extended by incorporating cooperative behaviors and an efficient algorithm called multi population ABC (or MPABC) is developed.

Radial analysis and scaling of urban land use

open access: yesScientific Reports, 2021
We determine the functional form and scaling law of radial artificial land use profiles in 300 European functional urban areas (FUAs). These profiles, starting from a fully artificial surface in the city center, decrease exponentially, the faster the ...

Limitations in creating artificial populations in agent-based epidemic modeling: a systematic review

open access: yesЖурнал микробиологии, эпидемиологии и иммунобиологии
Introduction. The key step in agent-based modeling of epidemics, which allows researchers to take into account individual characteristics of people, is the creation of an artificial population.

Single-artificial-atom lasing using a voltage-biased superconducting charge qubit

open access: yes, 2009
We consider a system composed of a single artificial atom coupled to a cavity mode. The artificial atom is biased such that the most dominant relaxation process in the system takes the atom from its ground state to its excited state, thus ensuring ...

Simulations Reveal the Power and Peril of Artificial Breeding Sites for Monitoring and Managing Animals [PDF]

open access: yes, 2017
Despite common use, the efficacy of artificial breeding sites (e.g., nest boxes, bat houses, artificial burrows) as tools for monitoring and managing animals depends on the demography of target populations and availability of natural sites.
