We introduce a novel layered fuzzy architecture that avoids rule explosion. Unlike a single layer union rule configuration (URC) fuzzy system, a layered URC fuzzy system can approximate any surface without the need of burdensome “corrective” terms. Further, we show that the URC fuzzy system is a generalized layered perceptron—an insight that allows one to choose interconnection weights in an in...

This paper introduces the traditional web and its limitations, and how these limitations can be overcome by putting the lights on a new interesting approach for the web which is the Semantic Web. The most common technologies that can be used to construct such smart web are discussed briefly, and then its current layered architecture models as proposed by Tim Berners-Lee and others are evaluated...

The classical TCPilP layered protocol architecture is beginning to show signs of age. In order to cope with. problems such as the poor manager ~ performance of wireless links and mobile terminals, including the high error rate of wireless network interfaces, power saving requirements, quality of service, and an increasingly dynamic network environment, a protocol architecture that considers cro...

In recent years a range of single programming language systems have been developed that are supported by a persistent store. Examples of such systems include Argus, Galileo, PS-algol and Smalltalk. Although each of these systems is based on a subtly different concept of persistence a common approach is to utilise a layered architecture. This paper presents the design of one such layered archite...

Understanding the business of organizations is a crucial point for developing good information systems supporting the organizations. Different generic business models have been developed based on the language action perspective. There are the models of Action Workflow (Medina-Mora et al, 1992; Denning & Medina-Mora, 1995), DEMO (Dietz, 1999) and BAT (Goldkuhl 1996; 1998). Inspired by these diff...

The architecture of a system is an indispensable mechanism required to map business processes to information systems. The terms architecture, layered architecture and system architecture are often used by researchers, as well as system architects and business process analysts inconsistently. Furthermore, the concept architecture is commonplace in discussions of software engineering topics such ...

This paper proposes several integrated security architecture designs for client-server group communication systems. In an integrated architecture, security services are implemented in servers, in contrast to a layered architecture where the same services are implemented in clients. We discuss the performance and accompanying trust issues of each proposed architecture and present experimental re...
