The major reason given in the philosophical literature for dissatisfaction with theories of vagueness based on fuzzy logic is that such theories give rise to a problem of higherorder vagueness or artificial precision. In this paper I first outline the problem and survey suggested solutions: fuzzy epistemicism; measuring truth on an ordinal scale; logic as modelling; fuzzy metalanguages; blurry ...

This contribution is the third and last of a series of talks on relations in higher-order fuzzy logic. The first two [5] have introduced the logical framework (see also [3, 4]) along with a set of basic results that, at first glance, look very familiar. These results, however, have been developed from a much more general basis. Their proofs have been devised independently and resemble closer to...

Context: In Higher Education where online courses are offered, one need is to predict the number of courses to be open. At date, some types of models have been used for this goal, such as models based upon machine learning, statistical and softcomputing approaches. Goal: To propose a softcomputing model for predicting the number of online courses (NOC) needed from the number of students enrolle...

In this paper, a D-Q model of fuzzy based unified power flow controller (UPFC) has been proposed to control the active and reactive power flow through the transmission lines. Power loss reduction also intends with the proposed UPFC controller. The UPFC’s shunt and series controllers are developed based on D-Q fuzzy logic (FL) controller, which has been designed in PSCAD environment as an indepe...

The objective of this paper is to develop a portfolio optimization technique that is simple enough for an individual with little knowledge of economic theory to systematically determine his own optimized portfolio. A compromise programming approach and a fuzzy logic approach are developed as alternatives to the traditional EV model.

E-learning took place between information and communication technology on one side and education on the other. Authoring shells are kind of e-learning systems capable for generating intelligent tutoring systems. These systems usually models learner’s knowledge by using overlay method during tests. In this paper is presented an advanced approach in refining and making flexible mark of learner’s ...

It is widely recognized that equational logic is simple, (relatively) decidable, and (relatively) easily mechanized. But it is also widely thought that equational logic has limited applicability because it cannot handle subtypes or partial functions. We show that a modest stretch of equational logic eeectively handles these features. Space limits preclude a full theoretical treatment, so we oft...

The Ministry of Human Resource of India, University Grants Commission and other stake holders are working together to ensure quality education to the coming generations. They have recommended certain parameters for the appointment and promotion of the teachers in the colleges and the universities so that the quality of teachers can be enhanced. In this research, a model based on fuzzy logic is ...

We introduce a simple translation from -calculus to combinatory logic (cl) such that: A is an sn -term i the translation result of A is an sn term of cl (the reductions are -reduction in -calculus and weak reduction in cl). None of the conventional translations from -calculus to cl satisfy the above property. Our translation provides a simpler sn proof of Godel's -calculus by the ordinal numbe...

The aim of this paper is to prove that fuzzy logic algorithm is a suitable control technique for fast processes such as electrical machines. This theory has been experimented on different kinds of electrical machines such as stepping motors, dc motors and induction machines (with 6 phases) and the experimental results show that the proposed fuzzy logic algorithm is the most suitable control tec...
