Fuzzy Logic and Fuzzy Sets 


History


Lotfi Zadeh, at the University of California at Berkeley, first presented fuzzy logic in the mid-1960's.

Zadeh developed fuzzy logic as a way of processing data. Instead of requiring a data element to be either a member or non-member of a set, he introduced the idea of partial set membership.

In 1974 Mamdani and Assilian used fuzzy logic to regulate a steam engine.

In 1985 researchers at Bell laboratories ....etc

Introduction
Many decision-making and problem-solving tasks are too complex to be understood quantitatively, however, people succeed by using knowledge that is imprecise rather than precise. Fuzzy set theory, originally introduced by Lotfi Zadeh in the 1960's, resembles human reasoning in its use of approximate information and uncertainty to generate decisions. It was specifically designed to mathematically represent uncertainty and vagueness and provide formalized tools for dealing with the imprecision intrinsic to many p ....etc

ABSTRACT
Fuzzy set theory and fuzzy logic are a highly suitable and applicable basis for developing knowledge-based systems in medicine for tasks such as the interpretation of sets of medical findings, syndrome differentiation in Eastern medicine, diagnosis of diseases in Western medicine, mixed diagnosis of integrated Western and Eastern medicine, the optimal selection of medical treatments integrating Western and Eastern medicine, and for real-time monitoring of patient data. This was verified by trials with the following systems t ....etc

Fuzzy Logic Applications in Wireless Communications
Various areas pertaining to wireless communication systems utilize fuzzy logic. It is very much useful in modeling the problems in which all the inputs are not known or are impossible to obtain. The fuzzy logic can be easily applied to non-linear and time-variant systems and address the complex problems in this domain. Reduction in complexity and robustness can be achieved by the use of fuzzy logic. Human expert knowledge is incorporated into a rule-based framework by the fuzzy logic. ....etc

An Introduction and Literature Review of Fuzzy Logic Applications for Robot Motion Planning
Abstract
This paper reviews fuzzy logic applications for robot motion planning. A short literature review is provided and three applications of fuzzy logic are considered: navigation and obstacle avoidance of a robotic vehicle in a 2D environment; a multilink industrial robot manipulator; and a robotic vehicle in a 3D environment. Scenarios are compared for their assignment of fuzzy sets, inference (rule base format and size), defuzzificat ....etc

Abstract

Here, students learn that the comparison of DNA sequences is important to a wide variety of applications in medicine and biology, including the analyses of ecosystem biodiversity, cancer mutations and the evolution of viruses. The students learn that specialized yet inexpensive digital hardware based on field programmable gate arrays can help speed the analysis of DNA sequences. They design and test a simple implementation of the Smith-Waterman algorithm that is broadly used for DNA sequence ....etc
