In this paper, a single-soliton two-component cellular automaton (CA) model of waves is presented as mobile self-localizations, also known as particles, waves, or gliders, in addition to its version with memory. The model is based on coding sets of strings where each chain represents a unique mobile self-localization. The original soliton models in CAs proposed with filter automata are briefly ...

In this line, before defining a syntax for a rule language, the rule language itself should be created. We should aim to define the language in terms of entities, components and relationships. The business rule community already has an established to discuss rules from which we can draw. Sub-communities, such as inference vs. ECA rules, forwardchaining vs. backwards-chaining, each have their ow...

Modern Web development is more and more moving towards the production of fullfledged, complex Web applications, possibly equipped with active and/or adaptive behaviors. On the one side, this evolution implies higher development costs and times; on the other side, such implications are contrasted by the dynamics of the modern Web, which demands for even faster application development and evoluti...

As XML is becoming widely accepted as a mean of storing, searching and extracting information, a larger number of Web applications will require conceptual models and administrative tools to organize their collections of documents. Recently, event-condition-action (ECA) rules have been proposed to provide reactive functionality into XML document databases. However, logical inference mechanisms t...

The gap between theory and practice has been recognized and many research groups focus on the relation of formal specification methods for agent properties to the design of practical multi-agent system. In this paper, the design and implementation of a kind of agent called E-Agent which is based on the concepts from AgentSpeak(L) and ECA rules. E-Agent is formalized firstly and the tools develo...

The emphasis of this paper is to evaluate and demonstrate the applicability of the active rule paradigm in novel application domains. Briefly, an active rule capability is supported through the ECA (event-condition-action) rule abstraction. Occurrence of a defined event triggers the evaluation of a condition. If the condition evaluates to true, the action is carried out. Several aspects of the ...

System modeling, analysis and visualization are becoming a common practice for the design of distributed intelligent systems since the wide adoption of the Unified Modeling Language (UML). However, UML cannot describe important behavioral properties such as context awareness as required for ubiquitous computing. In this paper, we present Context Aware UML Sequence diagrams (CA UML-S), an experi...

As the information management paradigm shifts from data management to knowledge management, active rule support for various information services has become a practical approach to add intelligence to the existing information management systems. Various active rule systems have been developed using different rule description languages and, yet, their business logics are not sharable with each ot...
