This paper presents some theoretical considerations about the variance of a fuzzy set and introduces covering–based algorithm for computing bounds an interval Type–2 set. The proposed obtains all possible variances unlike other algorithms which are based on center centroid to obtain relative is proven be always bigger than absolute variance. A comparison given through different examples where s...

The aim of this paper is to introduce and study set- valued homomorphism on lattices and T-rough lattice with respect to a sublattice. This paper deals with T-rough set approach on the lattice theory. The result of this study contributes to, T-rough fuzzy set and approximation theory and proved in several papers. Keywords: approximation space; lattice; prime ideal; rough ideal; T-rough set; set...

Motion drive algorithms are a set of filters designed to simulate realistic motion and an integral part contemporary vehicle simulators. This paper presents the design novel intelligent interval type 2 fuzzy adaptive algorithm for off-road uphill simulator. The off-road, simulator is used train assess driver’s behavior under varying operational environmental conditions in mountainous terrain. p...
