Remote monitoring and gathering information are the main objectives behind deploying Wireless Sensor Networks (WSNs). Besides WSN issues due to communication and computation restricted resources (low energy, limited memory computational speed and bandwidth), securing sensor networks is one of the major challenges these networks have to face. In particular, the security of sensors localization i...

The paper develops fuzzy attribute logic, i.e. a logic for reasoning about formulas of the form A ⇒ B where A and B are fuzzy sets of attributes. A formula A ⇒ B represents a dependency which is true in a data table with fuzzy attributes iff each object having all attributes from A has also all attributes from B, membership degrees in A and B playing a role of thresholds. We study axiomatic sys...

Obtaining a weaker condition that preserves some inspired topological properties is always desirable. As result, we introduce the concept of infra-fuzzy topology, which subset family degrades fuzzy topology by omitting closedness under arbitrary unions. Fundamental spaces are investigated, including open and closed sets, interior closure operators, boundary set. It not possible to expect latter...

Image classification is a process that may be affected by many factors. This paper is in regard of the classification techniques used for image processing and analysis using the concept of Fuzzy and Possibilities techniques, applied in each pixel of false-color satellite image By this paper examine classification approaches and the technique used for improving classification accuracy. By the in...

Fuzzy rough set (FRS) has a great effect on data mining processes and the fuzzy logical operators play key role in development of FRS theory. In order to generalize theory more complicated environments, we firstly propose four types neighborhood based covering by overlap functions their implicators this paper. Meanwhile, derived coverings from an original are defined equalities among function-b...

It is found that sub-pixel classifiers for classification of multi-spectral remote sensing data yield a higher accuracy. With this objective, a study has been carried out, where fuzzy set theory based sub-pixel classifiers have been compared with statistical based sub-pixel classifier for classification of multi-spectral remote sensing data.Although, a number of Fuzzy set theory based classifie...

Wireless Sensor Networks (WSN) offers proficient communication solution to the ever-present healthcare systems. The miniaturized sensors together with advance micro-electro-mechanical systems (MEMS) technology create a body sensor network (BSN) that continuously monitors the health condition of patients. Some of the other applications where WSN can be used are military, interactive entertainmen...
