Infrastructure as a Complex Adaptive System
Complexity, 2018 National infrastructure systems spanning energy, transport, digital, waste, and water are well recognised as complex and interdependent. While some policy makers have been keen to adopt the narrative of complexity, the application of complexity‐based methods in public policy decision‐making has been restricted by the lack of innovation in associated ...

Complexity Adaptive OFDM Systems [PDF]
2007 IEEE International Conference on Acoustics, Speech and Signal Processing - ICASSP '07, 2007 One disadvantage with current OFDM systems is, the system complexity associated with FFT module, equaliser, etc. is almost fixed and varies little with information bit rate. In this paper, based on an innovative "layered" concept in FFT algorithms, we propose a novel OFDM system whose complexity is adaptive to the desired bit rate and system ...

Urbanization favors high wage earners
npj Urban Sustainability, 2022 As cities increase in size, total wages grow superlinearly, meaning that average wages are higher in larger cities. This phenomenon, known as the urban wage premium, supports the notion that urbanization and the growth of cities contribute positively to ...

Influence Cascades: Entropy-Based Characterization of Behavioral Influence Patterns in Social Media
Entropy, 2021 Influence cascades are typically analyzed using a single metric approach, i.e., all influence is measured using one number. However, social influence is not monolithic; different users exercise different influences in different ways, and influence is ...

Industry Interconnectedness and Regional Economic Growth in Germany
Urban Science, 2021 Urban systems, and regions more generally, are the epicenters of many of today’s social issues. Yet they are also the global drivers of technological innovation, and thus it is critical that we understand their vulnerabilities and what makes them ...

Decentralization and heterogeneity in complex adaptive systems [PDF]
Kybernetes, 2015 Purpose– Following a bacterial-based modeling approach, the authors want to model and analyze the impact of both decentralization and heterogeneity on group behavior and collective learning. The paper aims to discuss these issues.Design/methodology/approach– Inspired by bacterial conjugation, the authors have defined an artificial society in which ...

A molecular approach to complex adaptive systems [PDF]
, 2007 Complex Adaptive Systems (CAS) are dynamical networks of interacting agents which as a whole determine the behavior, adaptivity and cognitive ability of the system. CAS are ubiquitous and occur in a variety of natural and artificial systems (e.g., cells,
