We develop a method for the simultaneous restoration and halftoning of ngerprints using the \M-lattice", a new non-linear dynamical system. This system is rooted in the reaction-diiusion model, rst proposed by Turing to explain morphogenesis (the formation of patterns in nature). But in contrast with the general reaction-diiusion, the state variables of the M-lattice are guaranteed to be bounde...

[1] Box counting is widely used for characterizing fracture networks as fractals and estimating their fractal dimensions (D). If this analysis yields a power law distribution given by N / r , where N is the number of boxes containing one or more fractures and r is the box size, then the network is considered to be fractal. However, researchers are divided in their opinion about which is the bes...

In nature, bacterial colonies must often cope with hostile environmental conditions. To do so they have developed sophisticated cooperative behaviour and intricate communication capabilities, such as direct cell ± cell physical interactions via extra-membrane polymers, collective production of extracellular `wetting’ fluid for movement on hard surfaces, longrange chemical signalling such as quo...

Explanation and argumentation are fundamental to reasoning. They are therefore of some importance to artificial intelligence. Discourse-based reasoning (DBR) is a knowledge representation technology that uses natural patterns of discourse as a basis for a structural ontology of explanatory and argumentative reasoning. By this means, we may ontologize the reasoning process itself, thus rendering...

Taking its historical point of departure in Heisenberg’s work, this article offers a view of quantum mechanics as, arguably, the first truly experimental and truly mathematical physical theory, that is, a theory concerned with experimenting with nature and mathematics alike. It is truly experimental because it is not, as in classical physics, merely the independent behavior of the system consid...

Introduction: Automatic mognition of handwritten characters and natural patterns has been one of the most difficult problems in artificial intelligence. Artificial neural networks (ANNs) constitute an important class of computational models for handling this class of problems. Many neural techniques have been proposed to solve this problem, such as those in [l 41. We propose an eficient way of ...

Optical systems with feedback are, generally, non-linear dynamic systems. As such, they exhibit evolutionary behavior. In the paper we present results of experimental investigation of evolutionary dynamics of several models of such systems. The models are modifications of the famous mathematical “Game of Life”. The modifications are two-fold: “Game of Life” rules are made stochastic and mutual ...

Modern science founded on the notions of “scientific materialism” projects an illusion that the conceptual framework of essentially propped up by linear theories is an adequate model of nature’s non-linear processes. If physicists, evolutionists, biologists or in general scientists believe that analytical science in its present form would reveal all the secrets of “life, the universe and everyt...

[1] This paper reviews theoretical and observational material on form and function of natural networks appeared in somewhat disparate contexts from physics to biology, whose study is related to hydrologic research. Moving from the exact result that drainage network configurations minimizing total energy dissipation are stationary solutions of the general equation describing landscape evolution,...

As the accuracy of conventional classifiers, based only on a static partitioning of feature space, appears to be approaching a limit, it may be useful to consider alternative approaches. Interactive classification is often more accurate then algorithmic classification, and requires less time than the unaided human. It is more suitable for the recognition of natural patterns in a narrow domain l...
