W odzis aw Duch and Norbert Jankowski In this paper relation between complex systems information theory and the simplest models of neural networks are elucidated Two di erent types of complex systems are distinguished new complexity measure based on the graph theory de ned hierarchy of the correlation matrices introduced and connection with the correlation matrix memories and other types of neu...

this paper we present a method of discrete modeling and analysis of multilevel dynamics of complex large-scale hierarchical dynamic systems subject to external dynamic control mechanism. In a model each state describes parallel dynamics and simultaneous trends of changes in system parameters. The essence of the approach is in analysis of system state dynamics while it is in the control loop. Ar...

for large and complex reacting systems, computational efficiency becomes a critical issue in process simulation, optimization and model-based control. mechanism simplification is often a necessity to improve computational speed. we present a novel approach to simplification of reaction networks that formulates the model reduction problem as an optimization problem and solves it using genetic al...

‎Financial market modeling and prediction is a difficult problem and drastic changes of the price causes nonlinear dynamic that makes the price prediction one of the most challenging tasks for economists‎. ‎Since markets always have been interesting for traders‎, ‎many traders with various beliefs are highly active in a market‎. ‎The competition among two agents of traders‎, ‎namely trend follo...

iran's current taxation system cannot utilize the other facilities of taxing as an instrument for regulating market. land is a production factor which the state can use it to impose tax for controlling the speculations, optimizing the current allocations and receiving the revenues. in this paper, we study a model on the effects of land value taxation in iran's economy in long run as a...

there are two dominant approaches to describe and understand the anatomy of complete health and well-being systems internationally. yet, neither approach has been able to either predict or explain occasional but dramatic crises in health and well-being systems around the world and in developed emerging market or developing country contexts. as the impacts of such events can be measured not simp...

In this supposed ‘information age’ a high premium is put on the widespread availability of information. Access to as much information as possible is often cited as key to the making of effective decisions. Whilst it would be foolish to deny the central role that information and its flow has in effective decision making, this paper explores the equally important role of ‘barriers’ to information...

This paper analyses managing higher education institutions in emerging economies. The paper investigates the case of postgraduate studies development at public universities. In so doing, it adopts the complex theory approach to evaluate how postgraduate studies have evolved in these countries. The investigation suggests that the postgraduate studies sector at public universities can be seen as ...

Often, the dynamics of large systems in Nature is governed by extrema1 events rather than typical events. This type of dynamics causes the system to self-organize into a critical, complex state. The approach to the complex attractor can be related to the behavior in the complex state itself. This behavior may be characterized as a fractal in c1 spatial plus one temporal dimension. The temporal ...
