The recent introduction of many agent-based systems and the increase in agent publications have made the area of agent-based systems a popular area. However, a number of challenges must be met before agent-based system development can claim to be fully mature. One of the most important challenges is the use of a comprehensive design approach whereby the design models fully support agent aspects...

Artificial life is largely concerned with systems that exhibit different emergent phenomena; yet, the identification of emergent structures is frequently a difficult challenge. In this paper we introduced a system to identify candidate emergent mesolevel dynamical structures in dynamical networks. This method is based on an extension of a measure introduced for detecting clusters in biological ...

the modeling investigation in this paper discusses the system level effects of a toxicant on a three species food chain system. in the models, we have assumed that the presence of top predator reduces the predatory ability of the intermediate predator. the stability analysis of the models is carried out and the sufficient conditions for the existence and extinction of the populations under the ...

The essence of obfuscation is to entangle the code and eliminate the majority of logical links in it. The offered theoretical apparatus allows describing obfuscated routines by concatenation of original and fake operational logics. This approach considers not only instructions or routines themselves, but the actions (results) they produce, what makes obfuscation a process of adding excessive fu...

We present five performance measures to evaluate grouping modules in the context of constrained search and indexing based object recognition. Using these measures, we demonstrate a sound experimental framework, based on statistical ANOVA tests, to compare and contrast three edge based organization modules, namely, those of Etemadi et al., Jacobs, and Sarkar-Boyer in the domain of aerial objects...

In the last decade many architectures for low-level image 2Image processing tasks. processing were developed. But simultaneously the image processing tasks were growing and changing, resulting in a As we look at tasks that are performed in image processing different set of basic operations than was needed ten years nowadays a few profiles can be sketched, without ago. An attempt is made to clas...

Abstract Visual processing has often been divided into three stages-early, intermediate, and high level vision, which roughly correspond to the sensation, perception, and cognition of the visual world. In this paper, we present a network-based model of intermediate-level vision that focuses on how surfaces might be represented in visual cortex. We propose a mechanism for representing surfaces t...

In this paper, we present Sail (Static Analysis Intermediate Language), a front-end which provides both a highand a low-level representation of programs and maintains a precise mapping from the low-level instructions to the high-level expressions and statements in the original source code. This two-level representation makes it easy to perform semantic analysis of programs on the low-level repr...

This paper investigates the hypothesis that the motivational system of an autonomous agent should be operationally coupled with the world it is situated in. Operational coupling is structural coupling plus explicit representation of problem parameters that are observable and adjustable and relies on the definition of regulatory, inter-dependent innate desires. This coupling is such that the age...

Two different sorts of retrieval in analogical tasks, novice-like and expert-like, have been demonstrated in psychological experiments. With recent computational work in object recognition as an inspiration, we propose the computation of intermediate features, and their use as triggers for retrieval, as the relevant constraint at the informational level of characterization of the retrieval proc...
