With the advances of technology, mobile robots are becoming increasingly popular. According to Karthiga (2014) developed countries get the assistance of mobile robots to rescue humans in disaster areas and this has been proven as a productive method to eliminate human error. In such instances robots are required to navigate in hostile environments such as collapsing buildings or areas affected ...

Fuzzy modeling of high-dimensional systems is a challenging topic. This study proposes an effective approach to data-based fuzzy modeling of high-dimensional systems. The proposed method works on the fuzzification layer and tries to use two-dimensional membership functions instead of onedimensional ones. This approach reduces fuzzy rule base radically due to using of two-dimensional membership ...

This paper addresses the development of organizational multi agent systems as a preferred solution to develop open, distributed and adaptive application. It proposes a combination between components and agents to define a flexible organizational model of MAS based on three concepts: roles, self-adaptive agents based on components and fuzzy groups. Roles are played by agents in fuzzy groups. A f...

When designing any type of fuzzy rule based system, considerable effort is placed in identifying the correct number of fuzzy sets and the fine tuning of the corresponding membership functions. Once a rule base has been formulated a fuzzy inference strategy must be applied in order to combine grades of membership. Considerable time and effort is spent trying to determine the number of fuzzy sets...

In this paper we present the application of a particular neuro-fuzzy system, named KERNEL, to the problem of differential diagnosis of erythematosquamous diseases, which represents a major problem in dermatology. A multistep learning strategy is adopted to obtain, starting directly from available data, a fuzzy rule base that can be used to identify the particular disease. The obtained classific...

This paper shows how to deene nonmonotonic logics from any classical logics L and any set X of formulas of L. In this context, the nonmonotonic inference relation`X is deened by A ` X B if every classical theorem of A B which is in X is a theorem of A. The properties of the relation`X are studied. We show, in particular, that the elementary properties (supraclassicity, or, left logical equivale...

Nodes in sensor networks can be easily compromised by an adversary due to hostile environments in which compromised nodes could be used to inject false reports into the network. The dynamic en-route scheme can detect and drop such false reports during the forwarding phase. In this scheme, choosing a threshold value is important as this gives a trade off between security of power and energy cons...

We present PROFIT, an advanced prototype system developed to estimate residential property values for real estate transactions. The system enhances Case-Based Reasoning (CBR) techniques with fuzzy predicates expressing preferences in determining similarities between subject and comparable properties. These similarities guide the selection and aggregation process, leading to the final property v...
