In this paper we present an agent-based fractal model of agile manufacturing enterprises. The agent-based model can be applied to all levels of the agile enterprise. A game-theoretic decisionmaking framework is also presented that considers various combinations of local and global objectives of the agents. Research issues in modeling of, and distributed decision-making in, agile manufacturing e...

In the last year, the TerraSAR-X sensor began to provide a great amount of data, thus increasing the possibility to extract valuable information from SAR images. Indeed, these high resolution images are increasingly more textured and present many details previously masked due to the low resolution of the available sensors. This certainly represents an advance for remote sensing applications, bu...

The seminal paper published by Leland et al. triggered a new direction on traffic modeling research, by unveiling the fractal nature of network traffic processes (Leland, Taqqu, Willinger, Wilson, & Bellcore, 1994). These authors experimentally demonstrated that the LAN Ethernet traffic collected in Bellcore Morristown Research and Engineering Center exhibits self-similar properties and burstin...

abstract purpose - the aim of this paper is to describe the population ecology theory through fractal thinking, an emergent human operating system that is creative, adaptive, healthy, and evolutionary; furthermore, a parallel is drawn between the population ecology model and the fractal structure. top-down hierarchies are typically characterized by command and control systems of the authority t...

In the Amazon, the development and paving of roads connects regions and peoples, and over time can form dense and recursive networks, which often serve as nodes for continued development. These developed areas exhibit robust fractal structures that could potentially link their spatial patterns with deforestation processes. Fractal dimension is commonly used to describe the growth trajectory of ...

The Urumieh-Dokhtar Magmatic Arc (UDMA) is recognized as an important porphyry, disseminated, vein-type and polymetallic mineralization arc. The aim of this study is to identify and subsequently determine geochemical anomalies for exploration of Pb, Zn and Cu mineralization in Mial district situated in UDMA. Factor analysis, Concentration-Number (C-N) fractal model and Local Linear Model Tree (...

Porous structures exhibiting randomly sized and distributed pores are required in biomedical applications (producing implants), materials science (developing cermet-based with desired properties), engineering (objects having controlled mass energy transfer smart agriculture (devices for soilless cultivation). In most cases, a scaffold-based method is used to design porous structures. This appro...

The traditional approaches of modeling and estimation of highly skewed deposits have led to incorrect evaluations, creating challenges and risks in resource management. The low concentration of the rare earth element (REE) deposits, on one hand, and their strategic importance, on the other, enhances the necessity of multivariate modeling of these deposits. The wide variations of the grades and ...
