Advanced Engineering Materials, EarlyView.Geometry‐driven thermal behavior in wire‐arc additive manufacturing (WAAM) influences microstructural evolution during nonequilibrium solidification of a chemically complex Fe–Cr–Nb–W–Mo–C nanocomposite system. By comparing different deposits configurations, distinct entropy–cooling rate correlations, segregation, and carbide evolution are revealed ...

Case-based complexity: within-case time variation and temporal casing
, 2021 We observe that time is central to most social dynamics and yet remains poorly understood. The complexity sciences have contributed a wide range of concepts and tools to investigate and recast time in social systems.

Hierarchical optimal configuration model and algorithm for counterterrorism resource allocation
Humanities & Social Sciences CommunicationsCounterterrorism resource allocation is a critical challenge, especially under financial constraints. Traditional location-allocation models often overlook the hierarchical structure of counterterrorism resources and the evolution of dynamic demand ...

Advanced Engineering Materials, EarlyView.A unified research data management framework for heterogeneous materials data is presented. The system integrates multimodal datasets using ontologies and knowledge graphs, enabling interoperability and FAIR (findable, accessible, interoperable, reusable) data principles. By linking data across scales and workflows, it supports reproducible, Artifitial

Complexity in Plasma - A Grand View of Self- Organization
, 1994 "The central theme of the Complexity is the inquest of the creation of ordered structure in nature. Extensive computer simulations on plasmas have revealed that self-organization is governed by the three key processes, i.e.

Teaching public administrators and leaders to handle complexity [PDF]
, 2018 Understanding and working under complexity has become ‘the new normal’ in public administration. Hence complexity must also be integrated into teaching and training of public administrators, not only in higher education but also in in-service training ...

Hierarchical Ensemble Learning for Automatic Classification of Construction Work Codes
Tehnički GlasnikThe Work Classification Code (WCC) serves as a critical tool for standardizing Bill of Quantities (BOQ) in construction projects, ensuring reliable cost estimation and effective expense management. However, current BOQ–WCC matching processes rely heavily

Global Optimization Based on Hierarchical Coevolution Model
, 2008 This paper presents a novel optimization algorithm that we call the particle swarms swarm optimizer ((PSO)-O-2), which based on a hierarchical coevolution model (HCO model) of symbiotic species. HCO model introduced a number of M species each possesses a
