Mechanism of self-organization in point vortex system

synthesis of platinum nanostructures in two phase system

چکیده پلاتین، فلزی نجیب، پایدار و گران قیمت با خاصیت کاتالیزوری زیاد است که کاربرد های صنعتی فراوانی دارد. کمپلکس های پلاتین(ii) به عنوان دارو های ضد سرطان شناخته شدند و در شیمی درمانی بیماران سرطانی کاربرد دارند. خاصیت کاتالیزوری و عملکرد گزینشی پلاتین مستقیماً به اندازه و- شکل ماده ی پلاتینی بستگی دارد. بعضی از نانو ذرات فلزی در سطح مشترک مایع- مایع سنتز شده اند، اما نانو ساختار های پلاتین ب...

Mechanism for Powerlaws without Self-Organization

A recent claim has been made that there must be a self-regulation in the waiting times to see hospital consultants on the ground that the relative changes in the size of waiting lists follow a power law [4]. In agreement with simulations of Frecketon and Sutherland, we explain the general non-selfregulating mechanism underlying this result and derive the exponent value −2 exactly. In addition, ...

Self-Organization in the Nervous System

Self-organization refers to a process in which the internal organization of a system increases in complexity without guidance from the outside world. In brain development many aspects of self-organization are involved. Although development of the nervous system depends on external stimulation, pattern formation in the brain is considered to be a result of internal interactions through unsupervi...

Guided Self-Organization in a Dynamic Embodied System Based on Attractor Selection Mechanism

Guided self-organization can be regarded as a paradigm proposed to understand how to guide a self-organizing system towards desirable behaviors, while maintaining its non-deterministic dynamics with emergent features. It is, however, not a trivial problem to guide the self-organizing behavior of physically embodied systems like robots, as the behavioral dynamics are results of interactions amon...
