Factors Affecting Student's Scientific Information Retrieval based on Fuzzy Logic Method Compared to Traditional Method

Background and aim: The aim of this study was to identify the factors affecting on students' performance in information retrieval based on fuzzy logic method compared to traditional method. Materials and methods: This survey-descriptive study was performed using quantitative approach. The research population was 34 PhD students, and the researcher-made questionnaire was used. Data were analyzed...

Spectrum Assignment in Cognitive Radio Networks Using Fuzzy Logic Empowered Ants

The prevalent communications networks suffer from lack of spectrum and spectrum inefficiency. This has motivated researchers to develop cognitive radio (CR) as a smart and dynamic radio access promised solution. A major challenge to this new technology is how to make fair assignment of available spectrum to unlicensed users, particularly for smart grids communication. This paper introduces an i...

Cognitive Cycle in Mind Model CAM

Cognitive cycle is a basic procedure of mental activities in cognitive level. Human cognition consists of cascading cycles of recurring brain events. This paper presents a cognitive cycle for the mind model CAM (Consciousness and Memory). Each cognitive cycle perceives the current situation, through motivation phase with reference to ongoing goals, and then composes internal or external action ...

Practical and Philosophical Applications of Fuzzy Logic: A Brief Introduction

Human beings are sometimes said to be different from mere computers and their associated algorithms (software) in that humans can reason and make decisions in settings where information is incomplete, conflicting, uncertain, imprecise or even partly wrong [1,2]. In recent decades workers in varied fields like computer science, psychology and cognitive engineering have attempted to “formalize” t...

Free Will and Advances in Cognitive Science

Freedom of will is fundamental to morality, intuition of self, and normal functioning of society. However, science does not provide a clear logical foundation for this idea. This paper considers the fundamental argument against free will, so called reductionism, and why the choice for dualism against monism, follows logically. Then, the paper summarizes unexpected conclusions from recent discov...
