Complexity , Information Loss and Model Building : from neuro - to cognitive dynamics

چکیده

A scientific problem described within a given code is mapped by a corresponding computational problem, We call complexity (algorithmic) the bit length of the shortest instruction which solves the problem. Deterministic chaos in general affects a dynamical systems making the corresponding problem experimentally and computationally heavy, since one must reset the initial conditions at a rate higher than that of information loss ( Kolmogorov entropy). One can control chaos by adding to the system new degrees of freedom (information swapping: information lost by chaos is replaced by that arising from the new degrees of freedom). This implies a change of code, or a new augmented model.

Role of Kaplan’s Preference Matrix in the Assessment of Building façade, Case of Gorgan, Iran

Buildings play a key role in organization and arrangement of city appearance. Specially, their facades have profound impact on the quality of urban landscapes while playing an important role in assessing urban environments by citizens. The introduction of superior building facades in terms of popular preferences is mostly based on visual elements of building facades. Furthermore, aesthetic pref...

A New Approach to Detect Congestive Heart Failure Using Symbolic Dynamics Analysis of Electrocardiogram Signal

The aim of this study is to show that the measures derived from Electrocardiogram (ECG) signals many a time perform better than the same measures obtained from heart rate (HR) signals. A comparison was made to investigate how far the nonlinear symbolic dynamics approach helps to characterize the nonlinear properties of ECG signals and HR signals, and thereby discriminate between normal and cong...
