The paper is concerned with supporting natural patterns of scientific collaboration in Access Grid environments. We reveal that no current approach to Access Grid allows dynamic session invocation within on-going Access Grid sessions nor workflow driven session triggering among users involved in that workflow. A model for a lightweight signaling architecture integrated within Access Grid is pro...

In this paper, crystallographic aspects of ancient, medieval and modern Turkish ornaments are dealt with. Crystallographic patterns (CPs) are considerably different from other patterns. The following are characteristic of CPs: the edge of ornament elements draws the edge of the figure; maximal compactness of the ornament elements; lack of background or transformation of background to ornament e...

Argumentation schemes have been developed in argumentation theory as stereotypical patterns of inference, abstract structures representing the material (semantic) relation and logical relation between the premises and a conclusion in an argument with a corresponding set of critical questions indicating their defeasibility conditions (Walton et al. 2008). They can be regarded as the modern inter...

A mutualism is an interaction where the involved species benefit from each other. We study a two-dimensional hexagonal three-state cellular automaton model of a two-species mutualistic system. The simple model is characterized by four parameters of propagation and survival dependencies between the species. We map the parametric set onto the basic types of space-time structures emerged in the mu...

-Template matching is a fundamental technique of pattern recognition. Although this technique is very general, its applicability has been limited because of the difficulty often encountered when fitting templates to natural data. Natural patterns are often distorted, misshapen, stretched in size, fuzzy, rotated, translated, observed at an unusual perspective, etc. Flexible templates (rubber mas...

In this paper we discuss how Fibonacci growth patterns are apparent in the structure of human language. We moreover show how familiar dynamics yielding these sorts of patterns in nature may be taken to apply, at some level of abstraction, for the human faculty of language. The overall picture casts doubts on any simplistic treatment of language behavior, of the sort stemming from classical beha...

Spontaneous symmetry breaking can result in emergence of complicated patterns in nature. Simple symmetry arguments can be used to describe beautiful and periodic rippled and wavy edges of flowers and leaves as well as fractal structure at the edge of a torn plastic sheet. In this paper, I will first discuss simple physical and geometrical arguments based on symmetry breaking and metrics on a cu...

We propose a method for synthesising head motion from speech using a combination of an Input-Output Markov model (IOMM) and Gaussian mixture models trained in a supervised manner. A key difference of this approach compared to others is to model the head motion in each angle as a series of templates of motion rather than trying to recover a frame-wise function. The templates were chosen to refle...

Humans are sensitive to complexity and regularity in patterns [YKM13, FK97]. The subjective perception of pattern complexity is correlated to algorithmic (Kolmogorov-Chaitin) complexity as defined in computer science [LV08], but also to the frequency of naturally occurring patterns [HGS10]. However, the possible mediational role of natural frequencies in the perception of algorithmic complexity...
