This paper describes the design and development of an expert system for tourist information center. The expert system was built to recommend a suitable travel schedule that satisfies user input constraints such as time period, budget and preferences. Tourist center officers need to answer similar set of queries in their day-to-day work which could be replaced by an intelligent tourist advisor s...

An electrostatic potential field (EPF) path planner is combined with a two-layered fuzzy logic inference engine and implemented for real-time mobile robot navigation in a 2-D dynamic environment. The environment is first mapped into a resistor network; an electrostatic potential field is then created through current injection into the network. The path of maximum current through the network cor...

Exploitation of architectural support for Prolog-like languages takes one of two main paths: compiler-based or interpreter-based. The former scheme enforces the transformation from a logic program to a set of instructions tailored for Prolog to accommodate the instruction-driven von Neumann processor, while the latter implements a complicated inference procedure as a microinterpreter to realize...

This paper proposes an opportunistic framework to modeling and control of multi-robots moving-target pursuit in dynamic environment with partial observability. The partial observability is achieved via the introduction of third party agent (referred to as mediator) that transforms the target’s as well as group members’ positioning information into the robotic agents’ common knowledge, thereby e...

A review paper on the various VLSI architectures of fuzzy logic based processors and controllers is presented over here. The focus of this paper on the study of low power VLSI implementation of fuzzy processors to result in reduced silicon area, high operating speed and the adaptability to various application domains. The paper reviews the design and implementation of different components of a ...

This paper is concerned with the stability analysis for T-S fuzzy control systems. By exploiting the property of the structure of fuzzy inference engine, an equivalence relation on index set of the product of fuzzy rule weights is defined. Further, a new stability criterion is proposed by using the equivalence relation, and formulated into progressively less conservative sets of linear matrix i...

Fuzzy Inductive Reasoning (FIR) is a methodology for qualitative modeling and simulation of systems behavior. FIR inference engine is based on the k-nearest neighbor (k-NN) rule, commonly used in the Pattern Recognition eld. The adaptation of the k-NN in an ad hoc 5-NN method has been proved to be very successful in the past, obtaining good results for diierent kind of systems. However, in some...

Due to shifting of healthcare data in electronic form, huge volumes of data have been accumulated in organizations related to medical claim processing domain. This paper presents design of a data warehouse implemented as integral part of a rule based expert system. The system is being used for scrubbing of medical claims’ data. Approximate star schema has been used for designing the proposed da...

Received Jul 19, 2013 Revised Oct 21, 2013 Accepted Nov 03, 2013 Nowadays expert system, being used in various fields has received a great deal of attention. Auditing is one such field, along with determining the audit opinion type. An expert system consists of a knowledge database and an inference engine. The objective of this research is to make an expert system that will be of help to audito...
